Abstract

The invention relates to a lock cylinder anti-theft structure and belongs to the class of machinery. The lock cylinder anti-theft structure comprises a key, a lock body, a lock cylinder and a plurality of lock plates, wherein a plurality of grooves are formed in the key, at least one slot is formed in an inner wall of the lock body, the lock cylinder is contained in the lock body and a plurality of lock plate holes are formed in the periphery of the lock cylinder and the plurality of lock plates are respectively arranged in the lock plate holes in a sliding mode. A hole penetrated through by the key is formed in the lock cylinder, at least one block plate hole corresponding to the slot is formed in the lock cylinder, at least one lock column portion is formed on at least one side of each lock plate, a block plate is arranged on each block plate hole in a sliding mode and a lock column correspondingly clamped with the lock column portion is formed at one side of the block plate. Therefore, when the key is inserted in the lock cylinder, the lock plates are driven to move simultaneously. When the lock column of the block plate is combined with the lock column portion of each lock plate, the block plate is far from the slot of the lock body and therefore a user can obtain a rotary key capable of being forward turned and counter turned at 360 degrees and the practical aim of increasing unlocking difficulty is achieved.

Description

technical field [0001] The present invention provides an anti-theft lock core, especially a lock core anti-theft structure capable of forwarding and reversing a key 360 degrees and increasing the difficulty of unlocking. Background technique [0002] Existing cleat type lockset, with car crutch lock words, as attached figure 1 As shown, it is the original implementation schematic Figure 1 , is a hollow cylinder 1, and the cylinder 1 is provided with a round hole 2, and the cylinder 1 is pierced with a sleeve 3, and one end of the sleeve 3 is provided with an integrated hexagonal tube 4, and the sleeve 3 is pierced A lock rod 5 with a circular insertion groove 6 is arranged, and the cylinder 1 is equipped with a lock core 10 assembly. The structure of the lock core 10 includes a lock core body 11 and several lock pieces with grooves 17 , the locking piece group 16 that spacers are formed, the rotating cylinder 15 and the cover 114 are formed, wherein the locking piece grou...
