[0002] Smart locks are improved upon traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. Users can unlock the door using fingerprints, passwords, card swiping, facial recognition, mechanical keys, and other methods, and are no longer limited to mechanical keys. This can avoid the problem of being unable to open the door due to forgetting to bring the key when using traditional mechanical locks, bringing great convenience to users.

[0003] At present, in order to ensure that the room is safer and difficult to enter, an anti-locking device is generally set on the inner door lock of the smart lock. The anti-locking of the existing smart locks all adopts a mechanical anti-locking device. After the anti-locking, the outer door lock cannot be directly unlocked normally by password or fingerprint input, resulting in failure to meet the use requirements of some application occasions.

[0004] Therefore, there are electronic anti-locking devices on the market, which use micro switches to perform electronic anti-locking. After the door is locked, it can be unlocked by the administrator password and key from outside, which can solve the above problem well. The micro switch of the existing electronic anti-locking device needs to be manually operated after opening or closing the door, which causes the user to often forget to unlock the door after going out, so that others cannot unlock the door, which is inconvenient to use.

[0052] Please refer to Figures 1 to 20 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a housing 10, a micro switch 20, an anti-locking block 30, an anti-locking pin 40, a first spring 50 and a second spring 60.

[0053] The housing 10 has a housing cavity 101. Specifically, the housing 10 includes a base 11 and a cover 12. The base 11 has a concave cavity 111 with an opening facing backwards. The cover 12 is arranged on the rear side of the base 11 to cover the opening of the concave cavity 111. The cover 12 and the base 11 surround and form the aforementioned housing cavity 101. The front side of the base 11 is provided with a strip hole 102 extending horizontally to the left and right. The strip hole 102 is connected to the housing cavity 101. The top of the base 11 is provided with a through hole 103, which is connected to the housing cavity 101. The cover 12 is locked on the base 11 by screws 13, and the structure is simple and easy to assemble. The overall profile of the housing 10 is T-shaped, with a compact structure and a reasonable layout. In addition, the base 11 has two fixing parts 112 arranged symmetrically on the left and right, and both fixing parts 112 are provided with fixing holes 104 so as to be fixedly installed with the lock body 72 by fixing screws 71.

[0054] The micro switch 20 is arranged in the accommodating cavity 101; in the present embodiment, the micro switch 20 has a trigger spring 21, and the micro switch 20 is connected to a connecting wire 22, which extends out of the outer shell 10, and the tail end of the connecting wire 22 is connected to a connector 23 so as to be electrically connected to the control board 73 of the smart lock 70.

[0055] The anti-locking block 30 can be disposed in the accommodating cavity 101 so as to be movable back and forth laterally. The anti-locking block 30 is located on the side of the micro switch 20. The anti-locking block 30 has a boss 31 for triggering the micro switch 20, and the anti-locking block 30 has a lever 32, which extends outward from the housing 10. In this embodiment, the lever 32 is adapted to the strip hole 102 and passes through the strip hole 102 to extend forward from the base 11, and a positioning column 33 extends from one end of the anti-locking block 30.

[0056] The reverse locking pin 40 is disposed in the accommodating cavity 101 so as to be movable back and forth vertically. The active end 41 of the reverse locking pin 40 extends outward from the housing 10. In the locked state, the reverse locking pin 40 and the reverse locking block 30 are positioned by the groove 301 and the convex portion 401. In this embodiment, the active end 41 of the reverse locking pin 40 passes through the through hole 103 and extends upward from the base 11. In addition, a positioning groove 42 is concavely provided at the lower end of the reverse locking pin 40. In addition, the groove 301 is located on the reverse locking block 30, and correspondingly, the convex portion 401 is located on the reverse locking pin 40.

[0057] The first spring 50 is disposed in the accommodating cavity 101, and the first spring 50 forces the anti-locking block 30 to move in the unlocking direction. In this embodiment, one end of the first spring 50 abuts against the inner wall of the accommodating cavity 101, and the other end of the first spring 50 is sleeved on the positioning column 33 to achieve a stable installation.

[0058] The second spring 60 is disposed in the accommodating cavity 101, and the second spring 60 forces the anti-locking bolt 40 to move in the locking direction. In this embodiment, one end of the second spring 60 abuts against the inner wall of the accommodating cavity 101, and the other end of the second spring 60 is embedded in the positioning groove 42 to achieve a stable installation.

[0059] The method of using this embodiment is described in detail as follows:

[0060] In unlocked state, Figures 4 to 6 As shown, the anti-locking block 30 is kept in close contact with the left side of the base 11 by the force of the first spring 50 and does not loosen. At the same time, the anti-locking pin 40 is kept in close contact with the anti-locking block 30 by the force of the second spring 60 and does not loosen. At this time, the trigger spring 21 of the micro switch 10 is in a free state and will not trigger the button of the micro switch 20.

[0061] When locked, if Figures 7 to 11 As shown, by manually operating the lever 32, the anti-locking block 30 is moved to the right, and the boss 31 on the anti-locking block 30 presses the trigger spring 21 of the micro switch 20 to trigger the button of the micro switch 20 to transmit the locking signal, and at the same time, the groove 301 of the anti-locking block 30 is aligned with the convex part 401 of the anti-locking pin 40. Then, the anti-locking pin 40 moves upward under the force of the second spring 60, so that the convex part 401 is embedded in the groove 301 for positioning, and the anti-locking pin 40 is always close to the anti-locking block 30 under the force of the second spring 60, so that the anti-locking block 30 is fixed and cannot move to the left, and maintains the locked state.

[0062] When unlocking, Figures 12 to 16 As shown, combined with Figures 17 to 20 When the handle 74 is pressed down (door opening) to drive the limit block 75 to rotate, the protrusion on the limit block 75 will touch the action end 41 of the anti-lock bolt 40. At this time, the anti-lock bolt 40 is moved downward by the force, so that the protrusion 401 of the anti-lock bolt 40 is separated from the groove 301 on the anti-locking block 30. Then, the anti-locking block 30 is moved to the left by the force of the first spring 50 until it is close to the left wall of the base 11. At this time, the trigger spring 21 of the microswitch 20 loses the pressure of the protrusion 31 of the anti-locking block 30, returns to the free state, releases the button of the microswitch 20, transmits the unlocking signal, and the lever 32 will automatically bounce to the unlocking mark to complete the unlocking and maintain the unlocking state.

[0063] like Fig. 20As shown, the handle 74 cannot be lifted to unlock the door. The reason is that after the handle 74 is lifted, the protrusion on the limit block 75 does not touch the action end 41 of the anti-locking pin 40, and the anti-locking pin 40 is not subjected to the downward pressure and cannot move downward, thereby failing to unlock the electronic anti-lock.

[0064] The design focus of the utility model is that a micro switch, an anti-locking dial block, an anti-locking pin, a first spring and a second spring are arranged in the shell, and the anti-locking pin is linked with the handle. After the electronic anti-locking, when going out, you only need to press down the handle to automatically unlock the electronic anti-locking, so as to prevent others from being unable to unlock the door by forgetting to unlock it after going out. It is more convenient to use, and the door cannot be unlocked by lifting the handle, so as to prevent unlocking when the handle is lifted outside the door. At the same time, it is not affected by the left / right direction of the handle. After the direction of the handle is changed, no other operation is required and it can be used normally.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
