Abstract

The invention relates to a gate lock mechanism, which comprises a left lock cylinder body and a right lock cylinder body, wherein the left lock cylinder body and the right lock cylinder body are connected mutually; a left lock cylinder shaft and a right lock cylinder shaft are in insertion connection in the left lock cylinder body and the right lock cylinder body, respectively; an unlocking poking wheel is arranged between the left lock cylinder body and the right lock cylinder body; the unlocking poking wheel and the left lock cylinder shaft are in transmission connection by a left transmission block; the unlocking poking wheel and the right lock cylinder shaft are in transmission connection by a right transmission block; a balance spring is arranged between the left lock cylinder shaft and the left transmission block and between the right lock cylinder shaft and the right transmission block respectively; a pushing spring is arranged between the adjacent left transmission block and the right transmission block in the unlocking poking wheel; a pin hole is formed both on the left transmission block and the right transmission block; a top spring and a lock pin are assembled in the pin hole; and lock holes matched with the opposite lock pins are formed on the left lock cylinder body and the right lock cylinder body. With such design, the unlocking poking wheel is restricted actively in rotational opening when the lock cylinder body at one side is damaged by violence; and the gate lock mechanism has the advantages of simple and compact structure design, strong anti-theft performance, wide application scope and high reliability.

Description

technical field [0001] The invention relates to a door lock mechanism. Background technique [0002] Existing common door lock, under the situation that one side lock core body is destroyed violently, the thief can open the door lock by stirring the unlocking dial, therefore, its anti-theft performance is not very perfect from a certain point of view. Contents of the invention [0003] In order to overcome the problem that the anti-theft performance of ordinary door locks in the prior art is not perfect when they are violently damaged, the present invention provides a door lock mechanism, which has a compact structure design and can withstand a certain degree of violence. When it is damaged, it can actively limit the rotation and opening of the unlocking dial, which enhances the anti-theft performance and high reliability. [0004] The technical solution adopted by the present invention to solve the technical problem is: comprising a connected left lock core body and a ri...
