Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of door locks, and in particular relates to a driving mechanism for a door lock bolt. Background Art
[0002] Glass door locks are used to be installed on glass doors to lock the door to prevent others from opening the door. Glass door locks are equipped with a lock tongue. When the door needs to be opened, the lock tongue is retracted by operating the lock, and the door can be easily pushed open. After closing the door, the lock tongue will automatically extend or lock the door through simple operation.
[0003] In the existing glass door lock, when the lock tongue in the lock is driven by a key, the key is inserted and turned, the key rotates the lock core, the rotation of the lock core drives the transmission rod to move, the transmission rod then pushes the cam to rotate, and the special shape of the cam converts the rotational motion into linear motion, thereby pushing the lock tongue to extend or retract. Although the above can drive the lock tongue to move, since there are many parts driving the lock tongue to move, the contact between the many parts will produce more friction and resistance, which may affect the smoothness of the movement of the lock tongue after long-term use, making the unlocking and locking process less sensitive, bringing inconvenience to users, and the complex structure will also increase the difficulty and cost of production.

The lock shell is screwed and fixed to a threaded hole in the fixing seat by a first screw that penetrates the glass door. A lock core is rotatably connected in the fixing seat, and the lock core is connected to a lock tongue in the lock shell through a driving member. The key inserted in the lock core is turned and rotated, and the lock core is driven to rotate, so that the rotating lock core drives the lock tongue to extend out of the lock shell or retract into the lock shell through the driving member.
[0006] Preferably, the driving member is a lock core tail ruler, one end of which is connected to the lock core, and the other end of which passes through a first screw on the surface of the glass door and is connected to a rotating block in the lock housing.
