Background

The current popularity of intelligent door locks is high, and the requirements of people on the performance of lock bodies are gradually increased.

Intelligent door locks generally include two or more locking bolts that extend from the lock body and snap into a slot in the door frame to prevent the door from being opened. Compared with a telescopic bolt, the rotary bolt is generally used as a main bolt of a door lock due to high stability and wear resistance. The rotary lock tongue is driven to rotate by a driving piece and is rotated out of the lock body, so that the rotary lock tongue is inserted into a clamping groove in a door frame to finish locking the door.

The rotary lock body is used for a manual door lock, and the intelligent door lock is relatively less in application, so that on one hand, the lock tongue needs to be driven by a driving device, and the lock tongue also needs to be reversely moved by the driving device when being rotated out, and therefore, the rotary lock tongue is required to finish self-ejection when the door is closed, and the design is relatively complex. On the other hand, the existing driving device is mainly transversely arranged on a straight line with the lock tongue, the occupied transverse space is larger, and the general transverse width of the lock body is not too large due to the limitation of the door frame, so that the structure is very compact in design, and the precision requirement is high.
