The invention relates to an improved lock core mechanism, which comprises a lock mandrel outer sleeve, a lock mandrel, a flat-head marble and a sharp-head marble; a safety groove is arranged in the peripheral wall of the sharp-head marble; a sliding groove is arranged in the mandrel shaft; a safety sheet and a spring are mounted in the sliding groove; a long groove is arranged in the safety sheet; the long groove is provided with an expansion part matched with the sharp-head marble to vertically move and a contraction part matched with the safety groove; a passive pushing oblique plane is arranged at the end part of the safety sheet; a safety marble hole is arranged in the lock mandrel; a compression spring and a safety marble are arranged in the safety marble hole; the upper end part of the safety marble is matched with a reset groove arranged in the inner wall of the lock mandrel outer sleeve; and an active pushing oblique plane forming sliding-pushing fit with the passive pushing oblique plane is arranged on the side wall of the safety marble. By using the improved lock core mechanism, the defect that a conventional lock core mechanism is weaker in theft prevention performance is overcome; through the design, the theft prevention performance of a lock core is improved greatly by adopting the safety sheet and the safety marble which are matched with each other; and the improved lock core mechanism has the advantages of strong stirring prevention performance, convenience in unlocking operation and strong reliability.
Description
technical field [0001] The invention relates to an improved lock cylinder mechanism. Background technique [0002] In the traditional door lock cylinder mechanism, the password mechanism in the lock cylinder generally adopts upper and lower marbles or blades. The structure design of the upper and lower marbles is relatively simple, and the anti-theft performance is weak. It is locked by the cooperation of differently arranged blades and the groove of the lock core shaft outer cover. The anti-theft performance of its structural design is not strong, and the failure rate is relatively high during use. Contents of the invention [0003] In order to overcome the problems of weak anti-theft performance and high failure rate during use of ordinary door lock cylinder mechanisms in the prior art, the present invention provides an improved door lock cylinder mechanism, the improved door lock cylinder mechanism Strong anti-theft and anti-dial performance, easy to unlock and reliabl...
