Description

Technical Field

[0001] The utility model relates to the technical field of locks, and particularly relates to an electronic glass door lock. Background Art

[0002] An electronic glass door lock is a lock with multiple unlocking methods. Generally, it is connected to a glass door by clamping a front lock body and a rear lock body on opposite sides of the glass door. It can unlock by fingerprint recognition, face recognition, digital password, and cooperate with a motor to drive the lock core to rotate and drive the lock tongue to retract, and can also unlock by turning the lock core with a mechanical key to drive the lock tongue to retract, and can also unlock by turning the knob provided on the rear lock body to drive the lock core to rotate and drive the lock tongue to retract.

[0003] Among them, the non-drilling electronic glass door lock is more popular among users because it is easier and more convenient to install and does not damage the glass door. Since the non-drilling electronic glass door lock cannot directly insert a mechanical key into the rotating shaft that drives the lock tongue to rotate for locking and unlocking, it needs to realize the rotation of the rotating shaft and drive the movement of the lock tongue through the cooperation of gears and racks. In the prior art, an electronic glass door lock is disclosed, and the Chinese utility model application number is 202321671925X. It adopts a connecting transmission mechanism, and tooth plates are arranged at both ends of the connecting transmission mechanism. When the lock core is rotated by a key, the connecting transmission mechanism will drive the gear shaft connected to the lock tongue to rotate, so as to realize unlocking. The movement direction of the connecting transmission mechanism during unlocking is to move along the length direction of the clamping plate. In order to enable the connecting transmission mechanism to move smoothly, the installation space processed on the clamping plate is relatively large. The increase in the installation space of the connecting transmission mechanism will lead to a decrease in the clamping strength of the clamping plate. Summary of the Invention
