Abstract

The present invention provides a idling and tamper-resistant lock core structure, which includes a fixed bracket, and the fixed bracket includes a front circular column and a rear circular column fixed to each other, the front circular column and the rear circular column are coaxially arranged, and the front circular column A circular cylindrical outer ring is arranged inside the ring column, an annular groove is arranged on the inner peripheral surface of the outer ring, and an annular cylindrical inner ring is arranged inside the outer ring. The outer peripheral surface is provided with an annular protrusion surrounding the outer peripheral surface, the annular protrusion is placed in the annular groove, the inner peripheral surface of the inner ring member is provided with a locking tooth, and the front end of the outer ring member is provided with a square groove in the middle, The front end of the inner ring is located on the bottom of the square groove, and the rear end of the inner ring is closed and provided with a slider groove. The grooves of different keys in the present invention will make the angle of rotation between the inner ring and the outer ring different. , Only when the correct key is inserted, can the lock be unlocked. And when the wrong key is inserted, it can be turned but not unlocked.

Description

technical field [0001] The invention relates to the technical field of lock cylinders, in particular to an idling anti-prying lock cylinder structure. Background technique [0002] When the existing lock cylinder is in a normal state, the inner peripheral fixing part and the inner core body keep cooperating, the core body will not rotate idly, and the core body can be twisted and unlocked by inserting a correct key. Such a lock cylinder is easy to be inserted into the keyhole by a violent unlocking tool to forcibly twist the core body and then drive the outer ring to unlock. Not only the anti-theft performance is poor, but also the core body will be damaged. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an idling and tamper-resistant lock cylinder structure, which solves the problem that the lock cylinder will be damaged if twisted forcibly. [0004] The present invention is realized in the following way: an i...
