Embodiment Construction
[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 left lock core body 1 and the right lock core body 2 are provided with an unlocking dial wheel 6, between the unlocking dial wheel 6 and the left lock core shaft 4, the right lock core shaft 5 by the left transmission block 7, right The transmission block 8 is connected for transmission. One side of the left transmission block 7 and the right transmission block 8 forms a dial wheel convex connection 9, and the other side forms a lock cylinder convex connection 10. The lock cylinder convex connection 10 side can be axially slidably inserted into the lock The core shaft is driven to rotate by the lock core shaft, and the side of the pin 9 of the dial can be axially slidably ins...

The invention relates to a lock cylinder mechanism capable of preventing violent damage, which comprises left and right lock cylinder bodies, and the left and right lock cylinder bodies are respectively plugged with opposite left and right lock cylinder shafts, and an unlocking device is arranged between the left and right lock cylinder bodies. The dial, the unlocking dial and the left and right lock core shafts are respectively connected and driven by the left and right transmission blocks. One side of the left and right transmission blocks forms a protrusion for the dial and the other side forms a protrusion for the lock cylinder. The left lock Balance springs are provided between the mandrel and the left transmission block, between the right lock mandrel and the right transmission block, push springs are provided between the left and right transmission blocks, a sheath is provided in the left chamber of the unlock dial, and the left transmission The dial cam of the block passes through the opening on the sheath and is opposite to the dial cam of the right transmission block. The dial cam of the left transmission block is composed of a fixed part and a movable part, and the movable part is hinged on the left transmission block. The above-mentioned design can limit the rotation and opening of the unlocking dial when one side of the lock cylinder is violently damaged, and has the advantages of compact structure, strong anti-theft performance, wide application range and high reliability.
Description
Technical field [0001] The invention relates to a lock core mechanism capable of preventing violent damage. Background technique [0002] In the existing ordinary door lock, when one side of the lock core body is violently damaged, the thief can open the door lock by turning the unlocking dial wheel. Therefore, from a certain angle, its anti-theft performance is not very perfect. Summary 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 violent damage-proof lock cylinder mechanism. The structure design is compact, it can actively limit the rotation of the unlocking dial when encountering a certain degree of violent damage, strengthen the anti-theft performance, and have high reliability. [0004] The technical solution adopted by the present invention to solve its technical problem is: comprising a left lock core body and ...
