Protector of security door --- Snail Housekeeper · Smart Latch Trial Report

With the openness and transparency of unlocking technology, it is now easy to buy technologies and tools on the Internet. In addition, the corridor is full of advertisements for non-destructive unlocking, which has increasingly endangered the safety of our family property. The lock cylinder is also divided ABC Several levels, although the latest C Class A lock cylinder has the highest security, and it is difficult to unlock without damage. However, it is still possible to unlock without damage. Then, our family's property and safety will never be guaranteed. Is there any way to fundamentally prevent nondestructive unlocking? The answer is yes, that is to use snail housekeeper wisdom latch.

Snail Housekeeper · Smart Door Latch is an intelligent anti-theft product with full creativity and sense of technology, which can fundamentally prevent the thief from unlocking without damage, so that even if the thief can unlock without damage, or pick up the key, even if the lock cylinder can be turned from the anti-theft door, the anti-theft door can not be opened, and the thief can be refused. Is it amazing? Let's study this magic product with me.

1、 Unpacking

First of all, I would like to thank Lei Feng and the snail housekeeper for giving me the opportunity to try this time, so that I can experience the wisdom latch at the first time.

picture 01

After the package is received and opened, it can be seen that the outer package of the door lock is not very large. The environmental protection package of yellow kraft paper is covered with a red instruction label, which is very concise and eye-catching.

picture 02

After opening, you can see two pages of instructions, one is installation instructions, the other is app instructions. Below the explanation is our subject, the snail wisdom latch. The color of the samples sent this time is random, and I got the orange bolt.

picture 03

Take out the latch and fixing foam, and put four There are two snail bluetooth keys in the center and a steel plate stuck on the door lock to fix the latch.

  picture 04

All the accessories are here, and the steel sheet is fixed with 3M glue.

picture 05

The latch is a long strip with a simple front. There is only one large round button, and a circle is embedded around the button led There is a strip groove on the lamp and button to mark the position. This button can be rotated, and it is also the core part of the whole wisdom latch.

picture 06

There are two buttons on the side of the latch, which are used to remove the latch. Press and hold the buttons on both sides to remove it from the fixed steel sheet.

picture 07

When you turn it over, you can see a strip rotating groove, which is the core mystery. Insert the anti lock buckle into the groove, and the groove will rotate to drive the anti lock buckle, so that the smart latch can be used to control the ejection and withdrawal of the anti lock tongue, so as to achieve the function of internal anti lock.

picture 08

Here is a close-up of the core part of the anti lock, which is suitable for most oval and zigzag latches. The built-in rotating module of the door latch can be removed. It is estimated that the rotating module suitable for the anti latch can be easily replaced in the future due to the non-uniform appearance of the anti latch

picture 09

Below is the battery compartment cover, which needs four No. 5 batteries to work. There is a switch in the middle, which is used to adjust the clockwise and counterclockwise direction of the latch opening and closing. This will be mentioned later.

picture ten

The bottom is a height adjustable gasket, and the two sides are magnets. Considering that most of our anti-theft doors are steel, this magnet can be attached to the anti-theft door to play a fixed role. There is a knob at the tail, which can be used to adjust the height of the gasket. I will explain in detail in the later installation phase.

picture eleven

The whole latch and accessories are exquisite in workmanship, solid in materials, beautiful in appearance, and full of science and technology, giving a high-end and pleasing feeling.

2、 Principles

Many friends will wonder why this latch will 100% How about preventing nondestructive technology from unlocking? First of all, we should understand the update of anti-theft technology and the latest unlocking rules of anti-theft doors.

In fact, anti-theft door and anti-theft lock technology has also experienced several generations of updates and changes.

1. The original anti-theft door was an ordinary door. The inside of the door was fixed with an external lock to prevent theft.  

picture twelve

There was no door at that time N Point locking function, the door is the door, the lock is the lock, the anti-theft performance is almost zero . At that time, the unlocking rule was that the door could be opened with a key outside the door, and an extra turn after locking the door was an anti lock. After anti lock, the door could not be opened from inside. If the door is unlocked from the outside, the door can be opened from the inside. There is an anti lock bar on the inside of the lock, which means the door can be unlocked from the inside. At this time, the door cannot be opened from the outside. There is only one keyhole outside the door, which is used to open and lock the door

picture thirteen

Locking from the inside and outside are two independent functions. It makes it clear that external locking cannot be opened from the inside, and internal locking cannot be opened from the outside. After locking from the outside, once there is an emergency at home, people inside can't get out, and there is a great potential safety hazard. However, due to the underdeveloped technology of our country at that time, this kind of door lock even ruled our house thirty Years. I came from eight This kind of lock has been available since I was 18 years old. Until now, this kind of lock still appears in the world. This kind of lock was used in the old residential areas and doors.  

2. Later, the security door experienced a change and joined N Point locking function.

picture fourteen

so-called N Point locking means that when the key is turned to rotate the lock cylinder, the principle of mechanical lever is used to make the four frames of the anti-theft door protrude several expansion tongues, which is safer than the previous single point lock. Especially when the door is pried violently, the old single point lock is easy to be pried off, and the multi-point lock is not easy to be pried off. But for this multi-point locking door, the main door lock is still an independent anti-theft lock, and there are two key holes outside the door. One is the multi-point locking keyhole integrated on the iron door, and the other is the keyhole of an independent anti-theft lock.

picture fifteen

Exactly, these security doors are all used A Class I cross key, with the lowest anti-theft performance, is extremely easy to be unlocked without technical damage.

3、  The newly built residential areas in recent years are all the latest anti-theft doors. These anti-theft doors have only one fixed door handle and one keyhole outside the door. There is no obvious external anti-theft lock inside the door. The door locks are integrated into the anti-theft door.

picture sixteen

There is a rotary door handle inside the door, which can be opened by pressing down the door handle without locking. There is a key hole below the handle, and there is a turnable anti lock catch below the key hole. This kind of anti-theft door is suitable for our snail wisdom latch. The unlocking rule of this anti-theft door is: push the door to lock, and open the door indoors. After locking, the door outside rotates for one circle, and the main lock pops out N The security door will pop up at the same time N Click to lock the locking tab. At this time, the door cannot be opened through the door handle, but the door can be opened by inserting the door key into the key hole of the indoor door lock. When the anti lock latch is pulled from the interior to lock the door, the door lock will pop up an independent latch, which is only controlled by the anti lock latch inside the door, not by the key hole outside the door and inside the door. That is to say, the locking rule of this door is: push the door to lock, and press the handle to open the door indoors. The key outside the door can be turned to lock the door at multiple points, and the key inside the door can be turned to open the door. Similarly, after the key inside the door is locked, the key outside the door can also be used to open the door. However, when the inside of the door is turned to lock the door, the key cannot be used to open the door outdoors, and of course, the key cannot be used to open the door indoors. The door can only be opened after the independent anti lock tongue is retracted after the indoor anti lock buckle is rotated in the opposite direction. This is the rule formulated with full consideration of the priority of indoor personnel over outdoor personnel. So we thought, if there was an intelligent robot in the room after leaving the door, it would be safer and completely prevent the lock from being unlocked without damage if it could automatically screw on the back lock and open the back lock when it came back? Therefore, the Snail Housekeeper Smart Latch is an intelligent machine specially designed for this purpose. When leaving the house door, the machine will be started to automatically lock the latch inside, so that the key can not be used outside to open the door, let alone to unlock without damage. This is the principle of snail housekeeper.

  3、 Fixed Article

Snail Steward Smart Door Latch is the simplest and easiest door lock device I have ever seen. It doesn't need to disassemble or replace any equipment, just stick the fixed steel sheet to the door lock, three It can be done in minutes.

  picture seventeen

First, clean the interior door lock cover. In order to paste better and more firmly, use cleaning products such as alcohol or detergent in advance to clean the outside of the lock cover. In particular, there should be no oil stain, otherwise the paste effect will be affected. After cleaning, take out the tape 3M The adhesive stainless steel fixing piece, remove the sticker and aim at the anti lock buckle on the inside of the anti-theft door to paste and press for a period of time.

picture eighteen

  Be sure to align with the center, because if the center is not aligned, the rotation axis of the latch will not be consistent with the axis of the anti latch in the future, which will result in the fixed steel sheet and 3M The adhesive will be affected by the extra eccentric torque force, which will affect its firmness.  

picture nineteen

After pasting the fixed steel sheet, we adjust the angle of the reverse latch and the angle of the groove so that the groove of the latch can just buckle the reverse latch, and then the latch can be fixed on the fixed steel sheet. The rotation groove of the latch can be adjusted by inserting a one dollar coin and holding it, without fear of mechanical damage.

picture twenty

After installing the door lock, the door lock cover is higher than the surface of the anti-theft door. At this time, the bottom button can be rotated to extend the expansion gasket and adjust it to the vertical state of the latch. So far, the fixation is completed.

4、 Installation

At this time, remove the latch and open the battery compartment. Install four No. 5 batteries according to the electrode direction. After power on, the latch will have a voice welcome prompt, indicating that the latch has been powered on. The switch in the middle of the battery compartment is used to adjust the rotation direction of the lock door. When the switch is turned to the top, it rotates clockwise to unlock, and when the switch is turned to the bottom, it rotates counterclockwise to unlock. After switching the direction of the switch in the middle, it is necessary to pull the battery off and restart it, otherwise it will not work.

Press the large button on the front of the latch, the latch will rotate clockwise (counterclockwise 270° , and the green prompt light will flash, and the voice prompt will be reported after the stop: the unlocking is successful. After pressing the large button again, the latch will rotate counterclockwise (clockwise 270° , and the blue prompt light flashes. After stopping, the voice prompts that the locking is successful. Each press will cycle back and forth between unlocking and locking.

The actual rotation angle of our anti lock buckle is 160° Left and right, although the latch rotates 270° However, when encountering hard resistance, the latch will automatically stop.

5、 Matchmaking

Snail housekeeper uses Bluetooth four Standard, can low power standby. Bluetooth starts as soon as the battery is installed twenty-four Work hour after hour. Scan the QR code on the instructions with your mobile phone, and you can download the snail housekeeper APP . Open APP After that, you need to use your mobile phone number to register or log in.

picture twenty-one

After login, the current snail steward is displayed in the middle of the main interface one The status and continuous protection time of No. 1 door latch. If it is paired, opening will automatically search for the connected door latch. After the connection is successful, the current status will be displayed. Click the middle circle to activate the latch to unlock or close.

Click the small lock on the left to pop up one Operation menu of No. 1 latch.

1. After clicking to activate the latch, the software will search for the latch. When the latch is found, the mobile phone will prompt you to press the round button on the latch, and then the pairing will be successful. This can increase security and allow criminals outside the door to use the snail APP The latch is searched, but the button inside cannot be pressed to pair. The Bluetooth used for the snail latch is one hundred and twenty-eight It is encrypted at the military level. Don't worry about being cracked by others.

2. Switching latches is to switch other latches. According to official instructions, every mobile phone APP Can be bound and managed one hundred A wisdom latch, and each latch can be one hundred Phones APP Administration. Since we only have one product on hand, we cannot evaluate this function.

three Latch nicknames are used to distinguish multiple paired latches. They can be individually marked for easy management.

four If the voice prompt is turned off, there will be no voice prompt every time the lock is opened or closed. However, functions such as paired key and low battery prompt are not affected by this voice off.

five Automatic locking is after unlocking thirty It will automatically close the door in seconds to increase security and prevent us from forgetting to lock the door after closing the door,

Press the right avatar button, and my information interface pops up. This software is registered with a mobile phone number.

There are also options below to activate the latch and toggle the latch. Since we only have one latch, we can't test to activate the new latch and switch the latch, and we don't know whether the activation and switching functions of the left side and the right side are the same. So on the night of the Lantern Festival on the 15th day of the first lunar month, we tried QQ After communicating with the official staff in the group, they got a reply that the functions on the left side are the same. Because the first version of the software is used now, the users are afraid that they can't find the functions, so they keep these two functions on the left side and the right side. After being updated in the future, the functions on the left side will be removed. The password modification is used to modify the login password. The function description is equivalent to help. We don't need to say much about the version update function.  

The snail housekeeper not only considers that we young people are familiar with mobile phone pairing and remote control, but also considers that the elderly people who do not use smart phones are equipped with two snail smart Bluetooth keys. This key is more convenient and fast to use. Press and hold the original button of the latch until the voice prompt for pairing the key appears, and then press the Bluetooth key to pair the Bluetooth key. Repeat the operation once to pair both keys. If you want to clear all keys, press the button for a long time. Keep hearing the prompt of clearing all keys. Press the latch button once to cancel pairing with all keys. The Bluetooth key can be charged, and there is a light on it. When the light turns red, it needs to be charged. Standard micro usb Plug in the mobile phone charger to charge. The voice prompt of the latch is very user-friendly. When the key is low on power, or five When the battery is low, voice prompts will be given.

  6、 Several notes 。

one As mentioned earlier, snail latch can be one hundred individual app The end is bound at the same time, and each app You can bind at most one hundred Department latch. It's enough for us.

two The official customer service said that in the worst case, if you forget your mobile phone and keys and are locked by the door latch, you can borrow your neighbor's mobile phone and install the snail housekeeper app After logging in with your own account, you can successfully connect and switch the lock. After my test, it is true. For a mobile phone that has never been paired, install it APP After logging in with my account, you can directly connect to the latch without re pairing and activation. Looks like the bolt and app The binding strategy of is to verify the account, not Bluetooth mac Address and pairing key. But there can only be one at a time app It can be connected to the door latch. Other app You cannot connect until this is disconnected. Multiple mobile phones app , you can use one account to log in, and you can log in at the same time. This login will not occur, and another device account will be offline.

three , Mobile app After connecting with the door lock for a period of time, if there is no operation, it will automatically disconnect. After testing with different mobile phones, the disconnection time is random, which may be 10 seconds or several minutes later. The purpose of disconnection is to connect another phone when needed. Otherwise, after the first person unlocks the door and enters, if the door is unlocked and the phone of the person inside is automatically connected, the phone outside the door will never be connected.

four 、 APP The function of activating the latch is equivalent to binding the latch. However, the current software is a beta version, which only provides the function of activating the latch, not the function of deactivating the binding. After communication with the official staff, the future official version of the software will provide the unbind function.

five The standby power consumption of the latch is very low. The new four batteries can be used for static standby three In 2006, it was used for half a year at a normal frequency, and it was equipped with a low battery prompt and an extremely low battery automatic door lock opening function. There was no need to worry about the battery failure of the rear latch after a business trip and the door could not be opened. Machine Bluetooth is based on one hundred and twenty-eight Bit military level encryption, basically unable to crack. The machine is equipped with dual hardware support function. If the main hardware fails, you can also use the auxiliary hardware to unlock the door. The safety must be OK.

6. The use of snail housekeeper does not mean that the burglary prevention at home is indestructible. Don't forget that there are windows at home. If the windows are not well protected and you happen to live on the first floor or the top floor, thieves can easily steal from the windows. Therefore, the door bolt steward is not omnipotent. To do a good job in anti-theft, we should start from many aspects.

7、 Suggestions and comments

one . The steel sheet is fixed with 3M The adhesive is stuck inside the door lock. If the door lock is flat, the adhesive will be firm. If it is a curved outer surface, follow 3M The contact area of glue is relatively small, which always gives people a feeling of insecurity.  

two , based on the one Some suggestions. I hope to add a fixed steel sheet at the same time that is not glued, but can unscrew the screws of the door lock cover, press the fixed steel sheet with the door lock cover and tighten the screws. This will be more secure, so don't worry 3 M The adhesive has failed for a long time, causing the steel sheet and the latch to fall off.  

three , based on the one Point and two It is suggested that we should register the patent as soon as possible, promote the industry standard, take the size of the fixed buckle of the snail latch as the national unified standard, and persuade some anti-theft door and door lock manufacturers to directly integrate the fixed buckle on the surface when the door lock mold is opened. So you don't have to 3M It is fixed, and can also do a good product promotion. For example, when a developer of a community uses this integrated buckle anti-theft door, he or she can give a set of intelligent door latches as a gift when buying a house with a full price. The community can also make a high-profile publicity about the use of snail smart door latches, the anti-theft and anti unlocking performance of the community is the first in the country, and the win-win situation depends on the operation ability of the Marketing Department and the Marketing Department.  

four It is suggested to add angle self-learning function to the rotation angle of the rotating shaft. Each time, the rotating shaft must be screwed to the point where it cannot be screwed, and it will stop only after encountering the maximum resistance. First, it will consume electricity. Second, it will be forced to stop after encountering resistance, increasing mechanical wear. Third, it will also bring reaction force to the fixed base after encountering resistance. The base may not stick firmly after a long time. If self-learning function is added, after opening and locking the door for the first few times, remember the maximum angle of opening and closing the lock, and you can stop the rotation in advance, which has many advantages. If it is not safe, you can reset the angle calibration once a week or two. On the phone APP The automatic learning rotation angle switch and reset angle switch are properly added.  

five . The automatic locking function is used after unlocking thirty The lock will be automatically closed in seconds. The function is very creative, but once it is opened, there will be a lot of trouble. Because if we are at home all the time during the day and people often come in and out of the house, this function will cause unnecessary trouble. If we only bring the key to go out and go downstairs to get a express to buy a drink, but forget to bring the mobile phone and Bluetooth key, we will be locked out of the room when there is no one at home at this time. Refer to my weloop now classic As for the bracelet, you can customize the no disturbance period. In fact, this function can be modified. You can define the time for automatically closing the lock, such as every night eleven The lock will be automatically closed at o'clock in the morning eight Click to start automatic locking. Because at night eleven It's time for us to sleep and rest. It's time for us to lock the door. morning eight When we all go to work, if it is too late to unlock the door when we leave, the latch will automatically unlock if it is detected that it is not locked when the time comes. This will be very practical and convenient. Less times of switching locks, increased standby time, reduced mechanical running time and mechanical wear, and reduced 3M The torque times of the glue increase the service life and safety stability of the latch in a disguised way.

six For the elderly, the Bluetooth key is too convenient. In terms of operation complexity, connection time and success rate, the Bluetooth key is more convenient than the smart phone APP It is very convenient and fast. The Bluetooth key can be pressed three Second to activate the latch, compared with the mobile phone APP Minimum required ten Seconds of operation time and connection time. It is hoped that the official will equip more Bluetooth keys as standard and sell them separately as treasures after the keys are mass produced.  

seven . There is a rubber pad in the middle of the expansion pad at the bottom of the latch. According to the actual measurement, the rubber pad is higher than two magnetic iron blocks, which causes the bottom of the latch is always uneven when it is adsorbed with the anti-theft door.

  picture twenty-two

actually I don't think the rubber gasket is very useful. It's better to be all magnets.

picture twenty-three

Just do something violent, buckle down the rubber pad, and directly attach two magnets to the security door, which is much more stable. After communicating with the official staff, they said that the rubber pad of the first batch of trial models was a bit too thick, and it will be ready when the official mass production version is ready.

eight . After communicating with the official staff, app After connecting the latch for a period of time, it will automatically disconnect, so that another phone can connect at any time. But the disconnection time is random. A unified time standard should be established, such as one Automatically disconnect after minutes, or customize the disconnection time.

8、 About start-ups in the future

I used to participate in the Meigubang evaluation held by Meizu Technology, I was lucky to win several signatures. This is the first time to win the lottery on Lei Feng's probation. In the past, the winning bid of Meidaoban was basically to receive the product, study it and write a report. Since winning the lottery this time, Lei Feng has set up a temporary trial official for us qq Discussion group, pull us in twenty The winning users, and several snail official engineers who are always online, are ready to answer our questions and solve our problems. Since receiving the product trial, we twenty The discussion and research between the winning bidder and the official engineer has never stopped. Everyone will ask questions to the engineer whenever they encounter something they don't understand. The engineer will patiently answer at any time. The engineer will carefully record and feedback our opinions and suggestions. Where our report is written, we will ask where it is. The group always keeps hundreds of activities every day.

picture twenty-four

I was especially moved by the question I asked on the 15th day of the first month, and a few minutes later I got the reply from the official engineer. From this point, it can be seen that start-ups in the future attach great importance to Lei Feng's trial link and the trial and feedback of lottery winning users. This is a responsible company that pays attention to user experience. With this point, the company's products will certainly have a very good prospect in the future, and the products will also sell well.

  It can be said that the Snail Housekeeper Smart Door Latch is a very creative product. It can be easily installed without removing and changing the lock of the anti-theft door, which can instantly raise the anti-theft level of the anti-theft door to a height where it can not be cracked and the door can not be unlocked without damage. It can also be unlocked in a variety of ways, including smart phones, It is also considerate to equip the elderly with Bluetooth keys. twenty-four Hour standby, Bluetooth four Super power saving, four Can achieve three Annual standby and half a year of normal use. Double sets of hardware backup and low battery reminder ensure safety. Today, when various manufacturers are making great efforts to research complex fingerprint, password, iris, network unlocking and other multi-functional locks, which are often tens of thousands of locks, start-ups in the future can go against the tide and find another way to redesign smart door locks with the most basic principles, the simplest installation, the smallest changes and the lowest cost, and improve the security level of anti-theft doors, This shows that start-ups in the future attach great importance to scientific and technological innovation and R&D capabilities. In addition, the company and its employees have a responsible attitude and focus on user trials and experience, twenty-four The hours of non-stop Q&A made our first batch of trial workers very moved. Based on these points, I believe that the future belongs to the nascent future.
