Abstract

The utility model relates to a lock core mechanism of door lock, which comprises a key, a lock core shaft outer sleeve and a lock core shaft in the lock core shaft outer sleeve, wherein center marble holes are oppositely opened in the lock core shaft outer sleeve and the lock core shaft, a special-shaped marble hole is arranged on the lock core shaft on the lateral portion of the shaft line of a key jack of the lock core shaft, and the center marble and the special-shaped marble are respectively engaged with special-shaped grooves on the left plugging surface and the right plugging surface of the key and password sprocket holes on an upper plugging surface and a lower plugging surface, and the password sprocket holes are left with residual sides which are on the same levels with the planes of the upper plugging surface and the lower plugging surfaces in the thickness direction of the key. The lock core mechanism of door lock overcomes the shortcomings in the prior art that a key must be firstly aligned to the direction before unlocking, the use is not very convenient, and the anti-theft property of a password mechanism is weaker, and the hand feeling for operation is bad. With the design, a lock can be unlocked after plugging the key in the positive and the negative directions in 180 degrees, and the use is very convenient, and the double-password mode further greatly improves the anti-theft property of a lock core. The lock core mechanism of door lock further has the advantages of strong anti-poking property, low failure rate and strong reliability.

Description

Door lock core mechanism

Affiliated technical field

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

Background technology

Traditional door lock core mechanism comprises key and lock core, and its key generally all adopts folk prescription to inserted mode, must aim at oppositely earlier before unlock operation, uses not very convenient; Cipher mechanism in the lock core adopts upper and lower pellet shot from a slingshot or blade, wherein the structure design of upper and lower pellet shot from a slingshot is simpler and cruder, theftproof performance a little less than, and adopt the lock core of blade as Cipher mechanism, all be that the blade arranged by difference and the groove fit of lock core shaft's overcoat lock, its structure design is also more common, theftproof performance is not strong yet, and in use the key of Cha Ruing swings easily, and the feel of operation is not good, comparatively speaking, fault rate is also higher.

Summary of the invention

In order to overcome the necessary first aligning direction before unlock operation of the key in the common door lock pin mechanism in the prior art, use not very convenient; The structure of Cipher mechanism is simple and crude, and theftproof performance is weak, the not good problem of feel of operation, and the utility model provides a kind of door lock core mechanism, and the unlock operation of this door lock core mechanism is convenient, antitheft anti-ly dials that performance is strong, fault rate is low, good reliability.

The technical scheme that its technical problem that solves the utility model adopts is: comprise key, lock core shaft in lock core shaft's overcoat and the lock core shaft's overcoat, the rotation of key interlock 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 in the pellet shot from a slingshot hole, center, central spring, 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 in 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 in the lock core shaft relative with groove, the sliding lock spare of installing contact groove in the through hole, between sliding lock spare two ends and the lock core shaft back-moving spring is set, the left side of key, right plug surface is provided with the special-shaped groove that matches with special-shaped pellet shot from a slingshot, on key, following plug surface is provided with the password perforation that matches with the center pellet shot from a slingshot, the password perforation leave on the thickness direction of key with on, the surplus limit that the plane of following plug surface is mutually concordant.

Special-shaped pellet shot from a slingshot in sliding lock spare, special-shaped pellet shot from a slingshot hole and the special-shaped pellet shot from a slingshot hole is in the bilateral symmetry setting in pellet shot from a slingshot hole, center.

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

The utility model is by above-mentioned specific design, inserting key on the direction of positive and negative 180 degree all can unblank, very easy to use, adopt the double code mode of special-shaped pellet shot from a slingshot and common spring also to improve the theftproof performance of lock core greatly, have and anti-ly dial that performance is strong, fault rate is low, the advantage of good reliability.
