Example Embodiment

[0015] As shown in the figure, the present invention includes a left lock core body 1 and a right lock core body 2 connected by a connecting rod 3. The left lock core body 1 and the right lock core body 2 are respectively inserted into the opposite left lock core shaft 4 and right The lock core shaft 5, the unlocking dial 6 is arranged between the left lock core body 1 and the right lock core body 2, one side of the connecting rod 3 has a downward extension and forms a fixed block 7, which can be set on the left lock core Between the shaft 4 and the unlocking dial 6, it can also be set between the right lock spindle 5 and the unlocking dial 6, according to specific needs, or left or right is just a choice of direction, not limiting the scope of protection, unlocking dial 6 The left lock core shaft 4 and the left lock core shaft 4 are connected for transmission by the left transmission block 8 passing through the fixed block 7, and the unlocking dial 6 and the right lock core sha...

Abstract

The invention relates to an improved lock cylinder mechanism. The improved lock cylinder mechanism comprises a connecting rod, a left lock cylinder body, a right lock cylinder body, a left lock cylinder shaft, a right lock cylinder shaft and an unlocking shifting wheel. One side of the connecting rod is provided with a downward extension, a fixing block is formed and arranged between the left lock cylinder shaft and the unlocking shifting wheel, the unlocking shifting wheel and the left lock cylinder shaft are connected through a left transmission block in a transmission mode, the unlocking shifting wheel and the right lock cylinder shaft are connected through a right transmission block in a transmission mode, a compression spring and a lifting pin are arranged in the right lock cylinder shaft, a balance pin is arranged in the fixing block, a sliding locking pin is eccentrically arranged in the unlocking shifting wheel in the axial direction, one end of the sliding locking pin abuts against the lifting pin, the other end of the sliding locking pin is matched with the balance pin, two annular grooves are symmetrically formed in the periphery plane of the sliding locking pin, two locking grooves are vertically formed in the unlocking shifting wheel in the radial direction, locking springs and locking pins are assembled in the locking grooves, and the locking pins and the annular grooves are matched. By means of the design, when damaged by violence, the lock cylinder body on one side can actively limit rotating opening of the unlocking shifting wheel, and the improved lock cylinder mechanism has the advantages of being compact in structure, high in anti-theft performance, wide in application range and high in reliability.

Description

technical field [0001] The present invention relates to an improved lock cylinder 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 destroyed, the present invention provides an improved lock cylinder mechanism. When a certain degree of violent damage occurs, it can actively restrict 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 left lock core body and a right lock core body connect...
