Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a gear-clutch self-spring-sensing detection lock body. Background Technology

[0002] The existing lock cylinders still have shortcomings. Specifically, when closing the door, the bolt of the existing mechanical lever lock cannot automatically and quickly extend, making it relatively easy for outsiders to push open the door, resulting in poor security.

[0003] Therefore, a gear-lock self-spring-sensing detection lock body is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a gear-clutch self-spring-sensing detection lock body to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gear-clutch self-spring-sensing detection lock body includes a lock shell, a lock body mechanism is provided on the outer wall of the lock shell, a guide plate is installed on the front of the lock shell, and a lock cover is installed on the outer wall of the lock shell;

[0007] The lock body mechanism includes a guide post fixedly connected to the outer wall of the lock case. A reversing torsion spring is installed on the outer wall of the lock case and on the back of the guide post. A reversing plate is provided on the outer wall of the reversing torsion spring. A lever is rotatably connected to the outer wall of the lock case and on the back of the reversing torsion spring. A sensing circuit board is fixedly connected to the outer wall of the lock case and on the back of the lever. An upper transmission gear is rotatably connected to the outer wall of the lock case near the sensing circuit board. A lower transmission gear is meshed with the outer wall of the upper transmission gear. A small lever is rotatably connected to the outer wall of the lock case near the lower transmission gear. A bolt head is installed above the small lever head. A stop plate is rotatably connected to the outer wall of the lock case near the bolt head. A contact tongue is slidably connected to the outer wall of the lock case above the stop plate. A beveled latch is slidably connected to the outer wall of the lock case near the contact tongue. A beveled latch is slidably connected to the outer wall of the lock case above the beveled latch.

[0008] As a preferred embodiment of this utility model, guide grooves are provided on the outer walls of both the lock shell and the lock cover.

[0009] As a preferred embodiment of this utility model, two sets of guide columns are provided, and the connection between the lower transmission gear and the lock housing is a rotatable connection.

[0010] In a preferred embodiment of this utility model, both the touch tongue and the oblique tongue penetrate and extend beyond the guide plate, and the touch tongue, the oblique tongue and the guide plate are connected by a sliding connection.

[0011] As a preferred embodiment of this utility model, both the touch tongue and the oblique tongue are trapezoidal in design, and the outer wall of the plug head is provided with a guide groove.

[0012] As a preferred embodiment of this utility model, the upper transmission gear is an irregularly shaped gear, and the dial shaft passes through and extends to the outside of the lock housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a gear-operated self-springing sensor lock body is designed. The lock body mechanism in this device is used to retract and extend the latch. After the door is closed, the latch and the bolt retract along the guide grooves on the lock shell and lock cover. After the latch contacts the latch sensor switch on the sensor circuit board, the sensor circuit board transmits a command to the fingerprint lock. The latch and the bolt continue to retract. After the latch contacts the stop plate, it moves the stop plate, causing the contact point of the stop plate on the bolt head to disengage, allowing the bolt head to automatically pop out. During the bolt head popping out, the small dial rotates counterclockwise along the guide groove that contacts the bolt head. During the counterclockwise rotation of the small dial, it drives the lower transmission gear to rotate. The rivet on the lower transmission gear disengages from the main bolt detection switch on the sensor circuit board, and the bolt pops out and resets, completing the door closing and locking. It can lock quickly after the door is closed without the need for manual locking by the user, improving security. It solves the problem that the bolt of the existing mechanical lever lock body cannot automatically and quickly extend when the door is closed, making it easier for outsiders to push open the door and resulting in poor security.
