Abstract

The utility model relates to a lock core which comprises a lock core shaft housing and a lock core shaft in the lock core shaft housing, central marble holes are oppositely arranged in the lock core shaft housing and the lock core shaft, a central marble and a central spring are arranged in the central marble holes, a key hole is arranged in the lock core shaft, the central marble holes vertically intersect the key hole, side marble holes are oppositely arranged on the lock core shaft housing and the lock core shaft which have the same axes with the key hole, and a side marble and a side spring are arranged in the side marble holes. The utility model overcomes the shortcomings of the common lock core structure with simple design and weaker burglary prevention property in the prior art, greatly improves the burglary prevention property of the lock core by the design through adopting the dual code mode of the central marble and the side marble, and has the advantages of compact structure, low cross unlocking rate and strong reliability.

Description

A kind of lock core

Affiliated technical field

The utility model relates to a kind of lock core.

Background technology

Traditional lock core generally all only adopts upper and lower pellet shot from a slingshot as Cipher mechanism, and the structure design of upper and lower pellet shot from a slingshot is simpler and cruder, the mutual opening rate height, its pick-proof, anti-dial and the performance of anti-technical unlocking a little less than, theftproof performance is not strong.

Summary of the invention

Simple and crude in order to overcome in the prior art common lock core structure designs, the problem that theftproof performance is more weak, the utility model provides a kind of lock core, and compact conformation, the mutual opening rate of this lock core is low, theftproof performance is strong.

The technical scheme that its technical problem that solves the utility model adopts is: comprise the lock core shaft in lock core shaft's overcoat and the lock core shaft's overcoat, the relative pellet shot from a slingshot hole, center of offering in lock core shaft's overcoat and the lock core shaft, installing center pellet shot from a slingshot and central spring in the pellet shot from a slingshot hole, center, be provided with key hole in the lock core shaft, pellet shot from a slingshot hole, center and key hole intersect vertically, with lock core shaft's overcoat of the same axis of key hole and lock core shaft on the relative side pellet shot from a slingshot hole of offering, installing side pellet shot from a slingshot and side spring in the side pellet shot from a slingshot hole.

Put outside the lock core shaft of the same axis opposite side in side pellet shot from a slingshot hole and be provided with installing hole, installing hole is sealed by sealing.

The utility model is by above-mentioned specific design, adopts the double code mode of center pellet shot from a slingshot and side pellet shot from a slingshot to improve the theftproof performance of lock core greatly, has that compact conformation, mutual opening rate are low, the advantage of good reliability.

The specific embodiment

As shown in the figure, the utility model comprises the lock core shaft 2 in lock core shaft's overcoat 1 and the lock core shaft's overcoat 1, the relative pellet shot from a slingshot hole, center 3 of offering in lock core shaft's overcoat 1 and the lock core shaft 2, installing center pellet shot from a slingshot 4 and central spring 5 in the pellet shot from a slingshot hole, center 3, be provided with key hole 6 in the lock core shaft 2, pellet shot from a slingshot hole, center 3 intersects vertically with key hole 6, with lock core shaft's overcoat 1 of key hole 6 same axis and lock core shaft 2 on the relative side pellet shot from a slingshot hole 7 of offering, installing side pellet shot from a slingshot 8 and side spring 9 in the side pellet shot from a slingshot hole 7.Be provided with installing hole 10 on lock core shaft's overcoat 1 of side pellet shot from a slingshot hole 7 same axis opposite sides, installing hole 10 is by sealing 11 sealings.When unblanking, insert key, the key moving center of the pushing tow pellet shot from a slingshot 4 that makes progress, the mating face that the mating face that makes 4 of upper and lower center pellets shot from a slingshot and lock core shaft 2, lock core shaft's overcoat are 1 flushes, password groove on the key sidewall is the side pellet shot from a slingshot 8 in the pushing tow side pellet shot from a slingshot hole 7 simultaneously, and the mating face that makes 8 of side pellets shot from a slingshot also flushes with the mating face of 1 of lock core shaft 2, lock core shaft's overcoat, at this moment, key can drive lock core shaft 2 and rotate together, reaches the purpose of unblanking.After the backward rotation key put in place and extracts key, upper and lower center pellet shot from a slingshot 4 and side pellet shot from a slingshot body 8 be the slippage dislocation under spring action, the lock core locking.

Claims (2)

1, a kind of lock core, comprise the lock core shaft in lock core shaft's overcoat and the lock core shaft's overcoat, the relative pellet shot from a slingshot hole, center of offering in lock core shaft's overcoat and the lock core shaft, installing center pellet shot from a slingshot and central spring in the pellet shot from a slingshot hole, center, be provided with key hole in the lock core shaft, pellet shot from a slingshot hole, center and key hole intersect vertically, it is characterized in that with lock core shaft's overcoat (1) of the same axis of key hole (6) and lock core shaft (2) on the relative side pellet shot from a slingshot hole (7) of offering, installing side pellet shot from a slingshot (8) and side spring (9) in the side pellet shot from a slingshot hole (7).

2, a kind of lock core according to claim 1 is characterized in that being provided with installing hole (10) on lock core shaft's overcoat (1) of the same axis opposite side in side pellet shot from a slingshot hole (7), and installing hole (10) is sealed by sealing (11).
