SUMMERY OF THE UTILITY MODEL

The main purpose of the present invention is to provide a lock core structure, which can effectively solve the disadvantages of the existing lock core in manufacturing and using.

The utility model relates to a lock core structure, which is mainly provided with a lock core seat, wherein the lock core seat is provided with a containing chamber, the wall surface of one end part of the lock core seat is provided with at least one pin hole penetrating through the containing chamber, a fixed pin is arranged in the pin hole, a lock core body is arranged in the containing chamber of the lock core seat, an anti-drilling part is arranged at one end of the lock core seat, the anti-drilling part is provided with a convex body, the convex body is arranged in the containing chamber of the lock core seat, the convex body is provided with a ring groove, the inner end part of the fixed pin is arranged in the ring groove of the anti-drilling part, and the anti-drilling part is provided with a key through hole.

The lock core structure of the utility model is characterized in that the anti-drilling component is made of steel.

The lock core structure of the utility model has the advantages that: the end of the lock core seat is provided with the anti-drilling component made of steel, so that a thief can form an idle state and cannot damage the lock core when the lock core is damaged by a drill bit by means of the anti-drilling component, the internal structure of the lock core can be made of cheaper metal materials such as zinc alloy and the like, the manufacturing cost of the lock core can be greatly reduced, and the optimal anti-theft effect can be achieved.
