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
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.
