Abstract

The utility model relates to an improved lock cylinder mechanism of a door lock, which comprises a lock cylinder shaft sleeve and a lock cylinder shaft in the lock cylinder shaft sleeve. A marble hole is arranged on the lock cylinder shaft at the side part of the axis of a key jack in the lock cylinder shaft, and a spring and a marble are arranged in the marble hole. Side marble holes are oppositely arranged in the lock cylinder shaft sleeve and the lock cylinder shaft at the side parts of the axis of the key jack, the axes of the side marble holes form included angles with the axis of the key jack, side marbles and side springs are arranged in the side marble holes, and both the side marbles and the marble are matched with a key inserted in the key jack. The improved lock cylinder mechanism of the door lock overcomes the defects of the prior art that the lock cylinder mechanism of a common door lock has poor theft-prevention property and high failure rate in the use process. By adopting the design, the theft-prevention property of the lock cylinder is greatly improved by adopting the double password modes of the marble and the side marbles. The improved lock cylinder mechanism has the advantages of strong theft-prevention property, low failure rate and strong reliability.

Description

A kind of improved door lock core mechanism

Technical field

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

Background technology

Traditional door lock core mechanism, general upper and lower pellet shot from a slingshot or the blade of adopting of Cipher mechanism in the lock core, wherein 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, the theftproof performance of its structure design is not strong yet, and fault rate is higher in the use.

Summary of the invention

For the theftproof performance that overcomes common door lock pin mechanism in the prior art is weak, fault rate problem of higher in the use, the utility model provides a kind of improved door lock core mechanism, and the unlock operation of this improved 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 the lock core shaft in lock core shaft's overcoat and the 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 hole is set, one side in pellet shot from a slingshot hole is communicated with key hole, assembling spring and pellet shot from a slingshot in the pellet shot from a slingshot hole, one 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 groove A8 is set respectively, groove B9, with groove A8, offer through hole in the relative lock core shaft of groove B9, the sliding lock spare of installing contact groove A and groove B is provided with back-moving spring between sliding lock spare two ends and the lock core shaft in the through hole; The relative lateral pins hole of offering in lock core shaft's overcoat of key hole axis sidepiece and the lock core shaft, the axis in lateral pins hole becomes installing lateral pins and lateral springs in the angle design lateral pins hole with the axis of key hole, lateral pins and pellet shot from a slingshot all match with insertion key in the key hole.

All there is setting in pellet shot from a slingshot hole and lateral pins hole in the axis both sides of key hole.

Pellet shot from a slingshot hole and lateral pins hole are in the dislocation cross arrangement of the axis both sides of key hole.

The utility model is by above-mentioned specific design, and the double code mode of employing pellet shot from a slingshot and lateral pins has 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.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an assembling drawing of the present utility model;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the B-B sectional view of Fig. 2;

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 lock core shaft 2, in the lock core shaft 2 of key hole 3 axis sidepieces pellet shot from a slingshot hole 4 is set, one side in pellet shot from a slingshot 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 hole 4, one side of pellet shot from a slingshot 6 forms projection 7 and gives prominence in key hole 3, on the inwall of the opposite side of pellet shot from a slingshot 6 and relative lock core shaft's overcoat 1 groove A8 is set respectively, groove B9, with groove A8, offer through hole 10 in the relative lock core shaft 2 of groove B9, the sliding lock spare 11 of installing contact groove A8 and groove B9 is provided with back-moving spring 12 between sliding lock spare 11 two ends and the lock core shaft 2 in the through hole 10; The relative lateral pins hole 13 of offering in lock core shaft's overcoat 1 of key hole 3 axis sidepieces and the lock core shaft 2, the axis in lateral pins hole 13 becomes the angle design with the axis of key hole 3, installing lateral pins 14 and lateral springs 15 in the lateral pins hole 13, lateral pins 14 and pellet shot from a slingshot 6 all match with insertion key 16 in the key hole 3, all there is setting in pellet shot from a slingshot hole 4 and lateral pins hole 13 in the axis both sides of key hole 3, pellet shot from a slingshot hole 4 and lateral pins hole 13 are in the dislocation cross arrangement of the axis both sides of key hole 3, this design, can increase the permutations of code number greatly, reduce mutual opening rate.When unblanking, key 16 inserts key hole 3, when inserting key 16, key 16 is the moving lateral pins 14 of pushing tow upwards, lateral pins 14 engages with password perforation 17 on key 16 plug surfaces, make the mating face and the lock core shaft 2 of lateral pins 14 centres, the mating face that lock core shaft's overcoat is 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 up and down each pellet shot from a slingshot 6, the groove A8 of pellet shot from a slingshot 6 opposite sides relatively aligns with the groove B9 slippage on lock core shaft overcoat 1 inwall, when key 16 will drive lock core shaft 2 and rotates together, one end of the transition face roof pressure sliding lock spare 11 of groove B9 and compress sliding lock spare 11 and lock core shaft 2 between the back-moving spring 12 that is provided with, the other end of sliding lock spare 11 is pushed groove A8 on pellet shot from a slingshot 6 sidewalls, make 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, B9 on groove A8 on pellet shot from a slingshot 6 sidewalls and lock core shaft's overcoat 1 inwall is relative, back-moving spring 12 discharges the end release groove A8, the other end that reset sliding lock spare 11 and enters groove B9, after extracting key, lateral pins 14 and each pellet shot from a slingshot be the slippage dislocation about in the of 6, the lock core locking.Above-described embodiment only is that the preferred implementation to a kind of improved door lock core of the utility model mechanism is described; 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 solution of the utility model all should fall into the protection domain of a kind of improved door lock core of the utility model mechanism.
