Embodiment Construction
[0017] 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, and the left lock core body 1 and the right lock core body 2 are respectively inserted into the opposite left unlocking handle 4 and the right lock core body. The mandrel 5, the unlocking dial 6 is arranged between the left lock core body 1 and the right lock core body 2, and one side of the connecting rod 3 has a downward extension and forms a fixed block 7, which is arranged on the right lock core shaft 5 and between the unlocking dial 6, and between the unlocking dial 6 and the left unlocking handle 4 are connected and driven by the left transmission block 8 passing through the unlocking dial 6. The front end of the left transmission block 8 forms a linkage chuck 8a, and the right lock cylinder The shaft 5 interlocks the right transmission block 9, and the front end of the right transmission block 9 forms an interlocking card slo...

The invention relates to an improved lock cylinder mechanism which comprises a left lock cylinder body and a right lock cylinder body which are connected with each other through a connecting rod. An unlocking push wheel is arranged between the left lock cylinder body and the right lock cylinder body, the unlocking push wheel is in transmission connection with a left unlocking handle through a left transmission block penetrating through the unlocking push wheel, and the front end of the left transmission block forms a linkage clamping head; a right lock cylinder shaft is in linkage with a right transmission block, and a linkage clamping slot is formed in the front end of the right transmission block and matched with the linkage clamping head; sliding locking pins are arranged in the unlocking push wheel up and down in the radial direction, one ends of the sliding locking pins are connected with compressed springs, the other ends of the sliding locking pins are matched with the right transmission block, and annular slots are formed in the circumferential faces of the sliding locking pins; two locking slots are formed in the unlocking push wheel up and down in the radial direction, locking springs and locking pins are assembled in the locking slots, and the locking pins are matched with the annular slots. In this way, rotation unlocking of the unlocking push wheel can be actively limited when the lock cylinder body of one side is broken violently, 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 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 connected by a ...
