Abstract

The utility model relates to a lock core, which comprises an outer jacket of a lock-core shaft and a lock-core shaft that is arranged inside the outer jacket, wherein, the outer jacket and the lock-core shaft are oppositely provided with a plurality of billiard holes; billiards and springs are arranged inside the billiard holes, a ring groove is arranged on the side wall of the billiards that is arranged inside the lock-core shaft, and a groove is arranged on the inner wall of the outer jacket corresponding to the opening position of the ring groove on the billiards, a through-hole groove is arranged on the lock-core shaft and is opposite to the groove, and a sliding locking part is arranged inside the through-hole groove. The utility model overcomes the weaknesses of the prior art that the structure design of the ordinary lock core is simple and the anti-theft performance is poor. With the design of the utility model, the anti-theft performance of the lock core can be greatly improved. The utility model has the advantages of compact structure, low malfunction rate, flexible opening/closing and high 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 only adopts all generally that pellet shot from a slingshot is as Cipher mechanism up and down, and its structure design is simpler and cruder, theftproof performance a little less than.

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 theftproof performance of this door lock core is strong, reliability is high.

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 of offering in lock core shaft's overcoat and the lock core shaft, installing pellet shot from a slingshot and spring in the pellet shot from a slingshot hole, offer annular groove on the sidewall of pellet shot from a slingshot in the lock core shaft, on the inwall of the relative lock core shaft's overcoat of open position, groove is set with the annular groove on the pellet shot from a slingshot, offer through-hole groove in the lock core shaft relative, installing sliding lock spare in the through-hole groove with groove.

The sliding lock spare of installing in the through-hole groove is a steel ball.

Outside lock core shaft, be provided with the ring set with its interlock, the setting through hole relative on the ring set with groove and through-hole groove.

Outside the pellet shot from a slingshot hole of lock core shaft's overcoat, be provided with gland.

The utility model has improved the theftproof performance of lock core greatly by above-mentioned specific design, has compact conformation, fault rate is low, switching is flexible, reliability is 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, the relative pellet shot from a slingshot hole 3 of offering in lock core shaft's overcoat 1 and the lock core shaft 2, installing pellet shot from a slingshot 4 and spring 12 in the pellet shot from a slingshot hole 3, offer annular groove 5 in the lock core shaft 2 on the sidewall of pellet shot from a slingshot 4, on the inwall of the relative lock core shaft's overcoat 1 of open position, groove 6 is set with the annular groove 5 on the pellet shot from a slingshot 4, offers through-hole groove 7 in the lock core shaft 2 relative, installing sliding lock spare in the through-hole groove 7 with groove 6.The sliding lock spare of installing is a steel ball 11 in the through-hole groove 7.Outside lock core shaft 2, be provided with the ring set 8 with its interlock, the through hole 9 relative with groove 6 and through-hole groove 7 is set on the ring set 8.Outside the pellet shot from a slingshot hole 3 of lock core shaft's overcoat 1, be provided with gland 10.When unblanking, insert key, key make progress pushing tow move the son 4, the mating face that makes 4 of upper and lower pellets shot from a slingshot and lock core shaft's overcoat 1 and lock core shaft 2, the mating face flush, pellet shot from a slingshot 4 aligns at the last through-hole groove 7 on its annular groove 5 and lock core shaft 2 in the journey, through hole 9 on the ring set 8 and the groove 6 on lock core shaft's overcoat 1 inwall of moving past, under the drive of key, lock core shaft 2, ring set 8 rotate together, one end of sliding lock spare steel ball 11 is brought into the annular groove 5 on the sidewall of through-hole groove 7 or through hole 9 and pellet shot from a slingshot 4, and, reach the purpose of unblanking along with lock core shaft 2 rotates together.When the backward rotation key puts in place, through-hole groove 7 in annular groove 5 on the pellet shot from a slingshot 4 and the lock core shaft 2, the through hole 9 on the ring set 8 and the groove 6 on lock core shaft's overcoat 1 inwall align again mutually, when extracting key, upper and lower pellet shot from a slingshot 4 is the slippage dislocation under the effect of spring 12, and an end of steel ball 11 pushed groove 6 on lock core shaft's overcoat 1 inwall, lock core double locking.
