Abstract

The utility model discloses a novel lock cylinder which comprises a lock cylinder casing, wherein a lock cylinder body is arranged in the lock cylinder casing. A longitudinal groove is arranged on the inner wall of the lock cylinder casing, a through hole is arranged on the circumference of the lock cylinder body, a control piece is arranged in the through hole, a long groove is arranged on the lock cylinder body, a blade and a partition piece are arranged in the lock cylinder body, and a protrusion of the partition piece is positioned in the long groove. A protrusion matched with a key is arranged in an inner hole of the partition piece, and the lock cylinder body and a transmission rod form an integrated structure. The novel lock cylinder has the advantages of being good in anti-theft performance, simple in structure and convenient to process.

Description

Lock core

Technical field

The utility model relates to a kind of lock core, particularly a kind of idle-run lock pin.

Background technology

Also occurred idle-run lock pin on the market, but existing idle-run lock pin adopts generally the mechanism of magnetic force or more complicated to realize, general the reducing along with magnetic of magnetic force, the theftproof performance of lock reduces, perhaps mechanism is complicated, processing difficulties, and perhaps theftproof performance is bad.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of lock core.

To achieve these goals, technical solution adopted in the utility model is:

Lock core comprises lock core shell, and lock core is arranged in the lock core shell, be provided with longitudinal fluting on the inwall of lock core shell, on the circumference of lock core through hole be set, control strip is arranged in the through hole, elongated slot is arranged on the lock core, blade and partition are arranged in the lock core, the projection of partition is positioned at long grain; The projection that cooperates with key is arranged in the endoporus of partition; Described lock core and drive link are structure as a whole.

The beneficial effects of the utility model: theftproof performance is good, and is simple in structure, is convenient to processing.

Fig. 4, Fig. 5 are respectively the schematic diagram of partition and blade.

The specific embodiment

See also its implementation process of description of drawings: lock core, comprise lock core shell 1, lock core 2 is arranged in the lock core shell 1, be provided with longitudinal fluting on the inwall of lock core shell 1, through hole 7 is set on the circumference of lock core 2, control strip 5 is arranged in the through hole 7, on the lock core 2 elongated slot is arranged, blade 3 and partition are arranged in the lock core 2, and the projection of partition is positioned at elongated slot; The projection that cooperates with key is arranged in the endoporus of partition; Described lock core 2 is structure as a whole with drive link 8.During use, key 6 is inserted in the keyhole 4, the recess 61 of key 6 is touched mutually with the pellet of lock core, when original key inserts, the breach of all blades 3 and partition all becomes a line, and control strip 5 is fallen in the breach, at this moment, during key turns, blade 3, partition rotate simultaneously with lock core 2.Lock core 2 is structure as a whole with drive link 8.So drive link 8 just can drive the tapered end motion.Only have the partition endoporus that one or two projection is arranged, also only have the partition outside that projection is arranged, so when not being first wife's key insertion, only can make the blade rotation of part, namely lamina idle-run.

Claims
