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 adopt upper and lower pellet shot from a slingshot or blade as Cipher mechanism, the structure design of 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 by 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

Simple and crude in order to overcome in the prior art common lock core structure designs, theftproof performance is weak, the not good problem of feel of operation, and the utility model provides a kind of lock core, the good reliability that compact conformation, the theftproof performance of this lock core is strong, fault rate is low, use.

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, in the lock core shaft of the key hole axis sidepiece of lock core shaft, special-shaped pellet shot from a slingshot hole is set, one side in abnormity pellet shot from a slingshot hole is communicated with key hole, assembling spring and special-shaped pellet shot from a slingshot in the abnormity pellet shot from a slingshot hole, one side of abnormity pellet shot from a slingshot forms projection and gives prominence at key hole, on the opposite side of abnormity pellet shot from a slingshot and the inwall of relative lock core shaft's overcoat groove is set respectively, offer through-hole groove in the lock core shaft relative with groove, the sliding lock spare of installing contact groove and groove in the through-hole groove, one end of each sliding lock spare is fused by lateral pin, is provided with back-moving spring between lateral pin and lock core shaft.

The relative pellet shot from a slingshot hole, center of offering in lock core shaft's overcoat and lock core shaft, installing center pellet shot from a slingshot, central spring in the pellet shot from a slingshot hole, center.

Abnormity pellet shot from a slingshot and the dislocation of center pellet shot from a slingshot are arranged.

The center pellet shot from a slingshot is arranged between two groups of abnormity pellets shot from a slingshot.

The utility model is by above-mentioned specific design, adopts the double code mode of special-shaped pellet shot from a slingshot and common spring to improve the theftproof performance of lock core greatly, has compact conformation, fault rate is low, switching is flexible, reliable high advantage.

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, in the lock core shaft 2 of the key hole 3 axis sidepieces of lock core shaft 2, special-shaped pellet shot from a slingshot hole 4 is set, one side in abnormity pellet shot from a slingshot hole 4 is communicated with key hole 3, assembling spring 5 and special-shaped pellet shot from a slingshot 6 in the abnormity pellet shot from a slingshot hole 4, one side of abnormity pellet shot from a slingshot 6 forms projection 7 and gives prominence in key hole 3, on the opposite side of abnormity pellet shot from a slingshot 6 and the inwall of relative lock core shaft's overcoat 1 groove 8 is set respectively, groove 9, with groove 8, offer through-hole groove 10 in the relative lock core shaft 2 of groove 9, the sliding lock spare 11 of installing contact groove 8 and groove 9 in the through-hole groove 10, one end of each sliding lock spare 11 is fused by lateral pin 16, between lateral pin 16 and lock core shaft 2, be provided with back-moving spring 15, the relative pellet shot from a slingshot hole, center 12 of offering in lock core shaft's overcoat 1 and the lock core shaft 2, installing center pellet shot from a slingshot 13 in the pellet shot from a slingshot hole, center 12, central spring 14.Abnormity pellet shot from a slingshot 6 can design two groups in lock core shaft 2, center pellet shot from a slingshot 13 is arranged between two groups of abnormity pellets shot from a slingshot 6, and special-shaped pellet shot from a slingshot 6 and the 13 formation dislocation arrangements of center pellet shot from a slingshot.In three groups of 16 pellets shot from a slingshot, the password number of above-mentioned arrangement can reach more than 40 hundred million.When unblanking, insert key, the key moving center of the pushing tow pellet shot from a slingshot 13 that makes progress, make, mating face that following center pellet shot from a slingshot is 13 and lock core shaft 2, the mating face that lock core shaft's overcoat is 1 flushes, the resistance that special-shaped groove on the key two side blocks the projection 7 of special-shaped pellet shot from a slingshot 6 one sides simultaneously and overcomes spring 5 slides up and down each special-shaped pellet shot from a slingshot 6, the groove 8 of abnormity pellet shot from a slingshot 6 opposite sides aligns with groove 9 slippages on lock core shaft overcoat 1 inwall, when key will drive lock core shaft 2 and rotates together, the transition face pushing tow lateral pin 16 and the compression reseting spring 15 of groove 9, one end of sliding lock spare 11 is pushed groove 8 on special-shaped pellet shot from a slingshot 6 sidewalls, make lateral pin 16 and sliding lock spare 11 along with lock core shaft 2 rotates together, reach the purpose of unblanking after key is rotated further and puts in place.When the backward rotation key puts in place, groove 8 and the groove 9 on lock core shaft's overcoat 1 inwall on abnormity pellet shot from a slingshot 6 sidewalls are relative, back-moving spring 15 discharges to reset the end release groove 8 of sliding lock spare 11, an end of lateral pin 16 is entered groove 9, after extracting key, upper and lower center pellet shot from a slingshot 13 and each special-shaped pellet shot from a slingshot be the slippage dislocation about in the of 6, the lock core locking.
