Abstract

The utility model relates to an improved lock cylinder mechanism which comprises an outer lock cylinder shaft sleeve, an inner lock cylinder shaft sleeve and a lock cylinder shaft, which are sleeved in sequence, the outer lock cylinder shaft sleeve and the inner lock cylinder shaft sleeve are assembled in a relatively fixed manner; the inner lock cylinder shaft sleeve and the lock cylinder shaft are oppositely provided with main password holes; each main password hole is internally provided with a main marble and a main spring, wherein the main marble is used for controlling the lock cylinder to perform unlocking or locking operation; the lock cylinder shaft is provided with a lock cylinder lug which is radially raised; the lock cylinder lug and the inner lock cylinder shaft sleeve are oppositely provided with auxiliary password holes; and each auxiliary password hole is provided with an auxiliary marble and an auxiliary spring. According to the improved lock cylinder mechanism, the defects of the common lock cylinder mechanism in the prior art, such poor anti-theft performance and high fault rate in use, are overcome. According to the above design, the anti-theft performance of the lock cylinder is greatly improved in a dual password mode of the main marbles and the auxiliary marbles, and the improved lock cylinder mechanism has the advantages of good anti-shifting performance, low fault rate and strong reliability.

Description

A kind of improved lock core mechanism
Technical field
The utility model relates to a kind of improved 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 through 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 lock core mechanism in the prior art is weak, fault rate problem of higher in the use; The utility model provides a kind of improved lock core mechanism, and the antitheft of this improved lock core mechanism 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 in the lock core shaft's overcoat, lock core shaft of sleeve successively and overlapping and lock core shaft; Cover relative fixed assembling in lock core shaft's overcoat and the lock core shaft; Offer main code hole relatively in cover and the lock core shaft in the lock core shaft; Be provided with main pellet shot from a slingshot, main spring that the control lock core is opened or locked in the main code hole; In lock core shaft, be provided with the cylinder cam of radial projection, put in cylinder cam and the lock core shaft and offer secondary code hole relatively, be provided with secondary pellet shot from a slingshot and auxiliary spring in the secondary code hole.
In lock core shaft, offer elongated slot, the bottom of cylinder cam is plugged in the elongated slot.
On cylinder cam, offer the locating notch relative with elongated slot, an end of fixture block passes elongated slot and gets in the locating notch, and it is fixing that lock core shaft is connected with cylinder cam.
Front end in cylinder cam is provided with anti-drilling projection, and the bottom of anti-drilling projection is plugged in the elongated slot.
The utility model is through above-mentioned concrete design, adopts the double code mode of main pellet shot from a slingshot and secondary pellet shot from a slingshot to improve the theftproof performance of lock core greatly, has anti-ly to dial that performance is strong, fault rate is low, the advantage of good reliability.

The specific embodiment
As shown in the figure; The utility model comprises cover 2 and lock core shaft 3 in the lock core shaft's overcoat 1, lock core shaft of sleeve successively; Cover 2 relative fixed assembling in lock core shaft's overcoat 1 and the lock core shaft; This relative fixed assembling can realize through the steady pin between the cover 2 in lock core shaft's overcoat 1 and the lock core shaft 15, and cover 2 also can become one structure in lock core shaft's overcoat 1 and the lock core shaft.Offer main code hole 4 relatively in cover 2 and the lock core shaft 3 in the lock core shaft; Be provided with main pellet shot from a slingshot 5, main spring 6 that the control lock core is opened or locked in the main code hole 4; In lock core shaft 3, be provided with the cylinder cam 7 of radial projection; Offer secondary code hole 8 relatively on the cover 2 in cylinder cam 7 and the lock core shaft, be provided with secondary pellet shot from a slingshot 9 and auxiliary spring 10 in the secondary code hole 8.Cylinder cam 7 can become one with lock core shaft 3 under the big condition of technology permission; Also can in lock core shaft 3, offer elongated slot 11; The bottom of cylinder cam 7 is plugged in the elongated slot 11 and direct relative fixed; The said fixing mode can also be on cylinder cam 7, to offer the locating notch 12 relative with elongated slot 11, and an end of fixture block 13 passes elongated slot 11 and gets in the locating notches 12, lock core shaft 3 is connected with cylinder cam 7 fixes.The design of cylinder cam 7 has reduced the movable space in the lock core shaft 3, has improved the anti-performance of dialling greatly.Front end in cylinder cam 7 is provided with anti-drilling projection 14, and the bottom of anti-drilling projection 13 is plugged in the elongated slot 11, and anti-drilling projection 14 is processed by high-strength alloy, and its design can significantly improve the anti-drilling performance of lock core.Main code hole 4 can be arranged many group dislocation designs more, can increase the permutations of code number greatly like this, reduces mutual opening rate.When unblanking, key 16 inserts lock core, and key 16 promotes main pellet shot from a slingshot 5 and secondary pellet shot from a slingshot 9; Make overlap 2 in mating face and the lock core shaft in the middle of the pellet shot from a slingshot, the mating face of 3 of lock core shafts flushes, key 16 can drive lock core shaft 3 and rotarily open together, extract key 16 after; Pellet shot from a slingshot slippage dislocation, the lock core locking.Above-described embodiment describes the preferred implementation of a kind of improved 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 improved lock core of the utility model mechanism.
