Description

Technical Field

[0001] The present invention relates to the field of intelligent anti-theft locks, and in particular to a clutch device of an intelligent anti-theft lock body and a use method thereof. Background Art

[0002] Smart anti-theft locks are locks built with modern intelligent technology. Compared with traditional mechanical door locks, smart anti-theft locks have significantly improved security and convenience. Smart anti-theft locks can not only be unlocked by fingerprint, password, card swiping, etc., but also have functions such as remote monitoring and anti-theft alarm, so that users can enjoy high reliability and high security under various working conditions. In the process of using smart anti-theft locks, the internal clutch device plays a vital role.

[0003] However, the current clutch device of the smart anti-theft lock body and the method of using the same still have some shortcomings. The clutch device of the existing smart anti-theft lock body and the method of using the same have not yet fully considered the anti-theft structure. In the process of using the clutch device of the smart anti-theft lock body and the method of using the same, if the clutch device of the smart anti-theft lock body and the method of using the same have not fully considered the anti-theft structure, then when the door handle is pressed in the state of uncompleted intelligent recognition, the idling state cannot be generated, and the lock tongue may still be retracted, resulting in a poor anti-theft effect and inconvenience for the staff to use the smart anti-theft lock body.

[0004] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and shortcomings, and provides a clutch device of an intelligent anti-theft lock body and a method of using the same. Summary of the invention

[0026] The specific operation is as follows. When the door is unlocked later, the connecting block 12 drives the connecting rod 7 to move, so that the limit plate 6 welded at the end of the connecting rod 7 moves accordingly, thereby causing the lock tongue 5 welded on one side of the limit plate 6 to move and move to the inner side of the fixed frame 3 to avoid obstruction when the door is opened later. After the restriction on the connecting block 12 is ended, the return spring 11 squeezed between the limit plate 6 and the fixed block 10 gradually returns to its original state, thereby driving the limit plate 6 and the lock tongue 5 to gradually return to their original position. In addition, during the movement of the limit plate 6 and the lock tongue 5, the limit piece 8 welded on one side of the limit plate 6 engages and slides on the outer side of the fixed rod 9 to ensure stability during the movement, avoid movement deviation, ensure smooth unlocking, and facilitate the staff to use the intelligent anti-theft lock body.

By rotating the connecting square rod 15, the connecting piece 14 is rotated. After being recognized by the intelligent anti-theft lock, the driving mechanism 17 receives the instruction to drive the arc plate 18 to move, so that the engaging piece 16 contacted by one side of the arc plate 18 moves. With the movement of the engaging piece 16, the other end of the engaging piece 16 gradually engages with the clutch block 13. Therefore, with the rotation of the connecting square rod 15, the connecting piece 14 drives the clutch block 13 It rotates synchronously. As the clutch block 13 rotates, the guide piece 21 above the clutch block 13 which is limited by the limit rod 20 moves accordingly. One end of the guide piece 21 is engaged and connected between the fixed block 10 and the connecting block 12. Therefore, as the guide piece 21 moves, the connecting block 12 moves to unlock the door. In addition, the staff can use the key to unlock the door. By turning the key, the connecting plate 22 is turned, so that the guide piece 21 connected to the connecting plate 22 is directly rotated to unlock the door. The structure is simple, which is convenient for the staff to use the smart anti-theft lock.

The connecting piece 14 is rotated by rotating the connecting square rod 15. After being recognized by the intelligent anti-theft lock, the driving mechanism 17 receives the instruction to drive the arc plate 18 to move, so that the engaging piece 16 contacted by one side of the arc plate 18 moves. With the movement of the engaging piece 16, the other end of the engaging piece 16 gradually engages with the clutch block 13. Therefore, with the rotation of the connecting square rod 15, the connecting piece 14 drives the clutch block 13 to rotate synchronously. With the rotation of the clutch block 13, the guide piece 21 set on the upper side of the clutch block 13 by the limiting rod 20 follows the movement, and one end of the guide piece 21 is locked. The lock is then unlocked by turning the key 22 so that the guide plate 21 can be rotated to move the connecting plate 22 so that the guide plate 21 connected to the connecting plate 22 is rotated to unlock the lock. The lock is then unlocked by turning the key 22 so that the guide plate 21 connected to the connecting plate 22 is rotated to unlock the lock. The lock is then unlocked by turning the key 22 so that the guide plate 21 connected to the connecting plate 22 is rotated to unlock the lock. The lock is then unlocked by turning the key 22 so that the guide plate 21 connected to the connecting plate 22 is rotated to unlock the lock. The lock is then unlocked by turning the key 22 so that the guide plate 21 connected to the connecting plate 22 is rotated to unlock the lock. The lock is then unlocked. The lock is then unlocked.
