Abstract

A lock cylinder comprises a lock shell, a lock body, a lock cylinder, an anti-drilling piece, a lock body spring, a marble, a tack, a locating pin, a locating pin spring, a locating piece, a locating piece spring, a steel ball, a key slot, a locating piece spring hole, a locating piece sliding slot, a key and curved teeth, the utility model has the beneficial effects that a convex semi-circle slot is adopted to combine with a curved slot, mechanical spring balls with two different structures are used and the locking function of card steel balls is used. The lock cylinder plays the functions of preventing locks from being pulled out and being opened by technique, and greatly improves the safety performance and the reliability of a lock.

Description

A kind of lock core
Technical field
The utility model relates to a kind of lock core, belongs to the anti-theft safety device technical field.
Background technology
The lock core of existing lockset is made of single lock cylinder, by several groups of pellets shot from a slingshot of just arranging, is withstood by spring in the pellet shot from a slingshot hole of lock core, and when key inserted lock core, key tooth top that extracts can rotate lock core, thereby opens lock.When extracting key, resilience in spring top resets pellet shot from a slingshot, stops lock core to rotate.This lock core is opened simple, and key is easily joined, and is stolen easily.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of lock core.The technical scheme that its technical problem that solves the utility model adopts is: comprise lock housing, lock body, lock gall, anti-drilling sheet, the lock body spring, pellet shot from a slingshot, tack, alignment pin, locating pin spring, spacer, the spacer spring, steel ball, key, the spacer spring eye, the spacer chute, key, bent tooth, be provided with lock gall in the lock body, lock gall is provided with key along connecting on its axis direction, be provided with the lock body spring in lock body and the lock gall, pellet shot from a slingshot, tack, lock body is with lock housing outward, lock body is equipped with anti-drilling sheet with outer inner room, key has adopted convex half slot and curved groove to combine, be provided with the spacer chute in the lock gall above or below equidirectional with key, spacer chute two ends are provided with the spacer spring eye, the centre is provided with steel ball hole, be provided with spacer in the spacer chute, be provided with the spacer spring in the spacer spring eye, spacer spring one end withstands on the lock gall, the other end withstands on the spacer both sides, be provided with steel ball in the steel ball hole, spacer is provided with the groove that meets the steel ball size, steel ball is pressed on the spacer, the both sides of key are provided with the location cotter way, are provided with locating pin spring and alignment pin in the cotter way of location.
Lock core is shaped on and the corresponding key of key, and described key is compound, in the above or below be provided with the card pellet shot from a slingshot on the corresponding curved tooth flower of card pellet shot from a slingshot head.
Benefit of the present utility model is to adopt convex half slot and curved groove to combine, and uses the mechanical hoodle and the card steel ball locking function of two kinds of different structures.Played anti-effect of dialling anti-technical unlocking.The safety and the reliability of lock have been improved greatly.

Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the utility model exploded perspective view;
Fig. 2 is the utility model lock gall elevation;
Fig. 3 is the utility model key upward view;
Fig. 4 is the utility model key elevation;
Fig. 5 is the utility model key rear elevation.
The specific embodiment
Embodiment 1: as shown in Figure 1, comprise lock housing 1, lock body 2, lock gall 3, anti-drilling sheet 4, lock body spring 5, pellet shot from a slingshot 6, tack 7, alignment pin 8, locating pin spring 9, spacer 10, spacer spring 11, steel ball 12, key 13, spacer spring eye 14, spacer chute 15, key 16, bent tooth 17, limiting the rotation of lock gall 3 between the contact surface of lock gall 3 and lock body 2 by several groups of pellets shot from a slingshot 6, pellet shot from a slingshot 6 is withstood by lock body spring 5, spacer 10 is housed in the lock gall 3 can exert pressure to pellet shot from a slingshot 6, the pellet shot from a slingshot 6 that is under pressure can be withdrawn in the lock body 2, spacer 10 is contained in the spacer chute 15 in the lock gall 3, can slide up and down, under key 16 tooth pressures during spacer 10 each pellet shot from a slingshot 6 just be withdrawn in the lock body 2 simultaneously, this moment, lock gall 3 can rotate, thereby lock is opened; When a key 16 was extracted lock core, pellet shot from a slingshot 6 returned to the origin-location under the promotion of lock body spring 5, hinder lock gall 3 and rotate in lock body 2, thereby lock can not be opened.
Embodiment 2: lock core is shaped on and the corresponding key of key shown in Fig. 2,3,4,5, and described key is compound, in the above or below be provided with the card pellet shot from a slingshot on the corresponding curved tooth flower of card pellet shot from a slingshot head.
