Description

A kind of lock core mechanism

Technical field

The utility model relates to a kind of lock core mechanism.

Background technology

Traditional lock core mechanism; Generally all adopt upper and lower pellet shot from a slingshot or blade as Cipher mechanism, the structure design of simple upper and lower pellet shot from a slingshot is simpler and cruder, theftproof performance a little less than; And the employing blade is as the lock core of Cipher mechanism; All be to lock through the blade of difference arrangement and the groove fit of lock core shaft's overcoat, its structure design is also more common, and theftproof performance is not strong yet; And in use, the key of insertion swings easily, and the feel of operation is not good, and comparatively speaking, fault rate is also higher.

Summary of the invention

In order to overcome the simplicity of design of the Cipher mechanism of common lock core mechanism in the prior art; Theftproof performance is weak, the not good problem of feel of operation; The utility model provides a kind of lock core mechanism, and the unlock operation of this lock core mechanism is convenient, antitheft is anti-dials that performance is strong, fault rate is low, good reliability.

The utility model solves the technical scheme that its technical problem adopted: comprise lock core shaft's overcoat and the lock core shaft that is actively socketed in lock core shaft's overcoat; In lock core shaft, in the lock core shaft of key hole axis sidepiece the pellet shot from a slingshot blind hole is set; One side of pellet shot from a slingshot blind hole is communicated with key hole; Assembling spring and pellet shot from a slingshot in the pellet shot from a slingshot blind hole, a side of pellet shot from a slingshot forms projection and gives prominence in key hole, on the inwall of the opposite side of pellet shot from a slingshot and relative lock core shaft's overcoat cunning is set respectively and pushes away groove, groove; Offer elongated slot with sliding pushing away in the relative lock core shaft of groove, groove; The sliding lockweight that pushes away groove and groove of installing contact in the elongated slot, the lockweight two ends are provided with back-moving spring, between the inwall of back-moving spring and lock core shaft's overcoat the lockweight retainer ring are set.

The annulus of lockweight retainer ring for not sealing, its end form gib head and are fixed in the lock core shaft through gib head.

Sliding and pushing away groove is skewed slot or arc groove, and lockweight is inclined-plane or arc surface with the sliding opposite face that pushes away groove.

In lock core shaft's overcoat and lock core shaft, offer pellet shot from a slingshot hole, center relatively, installing center pellet shot from a slingshot, central spring in the pellet shot from a slingshot hole, center, the bilateral symmetry setting in lockweight, pellet shot from a slingshot blind hole pellet shot from a slingshot hole at the center.

Pellet shot from a slingshot blind hole and the dislocation of pellet shot from a slingshot hole, center are arranged.

The utility model is through above-mentioned concrete design, and the double code mode of employing pellet shot from a slingshot and common spring has also improved the theftproof performance of lock core greatly, has and prevents that group performance is strong, fault rate is low, the advantage of good reliability.

The specific embodiment

As shown in the figure; The utility model comprises lock core shaft's overcoat 1 and the lock core shaft 2 that is actively socketed in lock core shaft's overcoat 1; In lock core shaft 2, in the lock core shaft 2 of key hole 3 axis sidepieces pellet shot from a slingshot blind hole 4 is set, a side of pellet shot from a slingshot blind hole 4 is communicated with key hole 3, assembling spring 5 and pellet shot from a slingshot 6 in the pellet shot from a slingshot blind hole 4; One side of pellet shot from a slingshot 6 forms projection 7 and gives prominence in key hole 3; Sliding push away groove 8, groove 9 are set respectively on the inwall of the opposite side of pellet shot from a slingshot 6 and relative lock core shaft's overcoat 1, offer elongated slot 10, the sliding lockweight 11 that pushes away groove 8 and groove 9 of installing contact in the elongated slot 10 with sliding pushing away in the relative lock core shaft 2 of groove 8, groove 9; Lockweight 11 two ends are provided with back-moving spring 15, between the inwall of back-moving spring 15 and lock core shaft's overcoat 1 lockweight retainer ring 16 are set.The annulus of lockweight retainer ring 16 for not sealing, its end form gib head 17 and are fixed in the lock core shaft 2 through gib head 17.The sliding groove 8 that pushes away is skewed slot or arc groove, and lockweight 11 is inclined-plane or arc surface with the sliding opposite face that pushes away groove 8.In lock core shaft's overcoat 1 and lock core shaft 2, offer pellet shot from a slingshot hole, center 12 relatively, installing center pellet shot from a slingshot 13, central spring 14 in the pellet shot from a slingshot hole, center 12, the bilateral symmetry setting in lockweight 11, pellet shot from a slingshot blind hole 4 pellet shot from a slingshot hole 12 at the center.Pellet shot from a slingshot blind hole 4 is arranged with 12 dislocation of pellet shot from a slingshot hole, center, and above-mentioned dislocation arrangement design can increase the permutations of code number.Insert key when unblanking; Key upwards promotes center pellet shot from a slingshot 13; The mating face that the mating face that makes 13 of upper and lower center pellets shot from a slingshot and lock core shaft 2, lock core shaft's overcoat are 1 flushes; The resistance that groove 18 on the key two side blocks the projection 7 of pellet shot from a slingshot 6 one sides simultaneously and overcomes spring 5 slides each pellet shot from a slingshot 6; The cunning of pellet shot from a slingshot 6 opposite sides push away groove 8 relatively with lockweight 11 and lock core shaft's overcoat 1 inwall on groove 9 slippages align, lockweight 11 under the effect of back-moving spring 15 with lock core shaft overcoat 1 inwall on groove 9 separate, key can drive lock core shaft 2 and lockweight 11, lockweight retainer ring 16 rotates unlatching together.When the backward rotation key puts in place; The groove 9 that cunning on pellet shot from a slingshot 6 sidewalls pushes away on groove 8 and lock core shaft's overcoat 1 inwall is relative, and after extracting key, spring 5 slides each pellet shot from a slingshot 6; Pushing away groove 8 promotion lockweights 11 through the cunning on the pellet shot from a slingshot 6 moves; The resistance that lockweight 11 overcomes back-moving spring 15 gets into groove groove 9, and upper and lower center pellet shot from a slingshot 13 is slippage dislocation up and down also, the lock core locking.Above-described embodiment describes the preferred implementation of a kind of lock core of the utility model mechanism; Be not that design and scope to utility model limits; Under the prerequisite that does not break away from the utility model scheme; Various external form modification and improvement that those skilled in the art make the technical scheme of the utility model all should fall into the protection domain of a kind of lock core of the utility model mechanism.
