Abstract

The utility model relates to a door lock cylinder capable of being opened from both sides. The door lock cylinder comprises a left lock cylinder body and a right lock cylinder body which are butted through a connecting rod, wherein a left lock cylinder shaft and a right lock cylinder shaft are oppositely inserted in the left lock cylinder body and the right lock cylinder body; an unlocking cam is arranged between the left lock cylinder body and the right lock cylinder body; one side of a left slide block with a flange and one side of a right slide block with a flange are mounted in the left lock cylinder shaft and the right lock cylinder shaft in an axially sliding manner, and are driven by the lock cylinder shafts through the flanges; the other sides of the left slide block and the right slide block are arranged in the unlocking cam in an axially sliding manner, and drive the unlocking cam through the flanges; springs opposite to the lock cylinder shafts are axially arranged in the left slide block and the right slide block; and the left slide block and the right slide block are movably connected through a pin shaft in the axial direction. Through the design, the door lock cylinder can be successfully opened when keys are inserted from both sides, and has the advantages of simple and compact structural design, wide application range and high reliability.

Description

Can two-sided unlatching door lock core

Technical field

The utility model relate to a kind of can two-sided unlatching door lock core.

Background technology

Common door lock core has inserted in a side under the situation of key, inserts key from the other end again and can't open, and therefore, has a lot of inconvenience in actual application.

Summary of the invention

For overcome under common door lock pin in the prior art inserted key in a side the situation again from the other end insert that key promptly can't open problem, the utility model provide a kind of can two-sided unlatching door lock core, the structure design that this can two-sided unlatching door lock core is simple compactly, two-sided inserts simultaneously that key all can be opened freely, good reliability.

The technical scheme that its technical problem that solves the utility model adopts is: comprise left lock core body and right lock core body by the extension bar butt joint, left side lock core body, the relative left lock core shaft of pegging graft in the right lock core body, right lock core shaft, be provided with the cam of unblanking between left side lock core body and the right lock core body, the left slider that has flange, right slide block one side can be installed in left lock core shaft axially slidably, drive by lock core shaft in the right lock core shaft and by flange, left slider, the opposite side of right slide block can be arranged in the cam of unblanking by flange axially slidably with the driving cam of unblanking, the spring relative with lock core shaft all axially is set in left slider and right slide block, on axis direction, flexibly connects between left slider and the right slide block by bearing pin.

In lock core shaft, be provided with the driving groove that matches with flange, on the cam of unblanking, be provided with the interlock groove that matches with flange.

Flange on the slide block becomes stepped.

The spring that axially is provided with in left slider and the right slide block is two.

The utility model is by above-mentioned specific design, can be implemented in both sides and inserts smooth unlatching under the key situation simultaneously, has that structure design is simple compact, applied widely, the advantage of good reliability.

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

Fig. 1 is the structural representation of the utility model when not inserting key.

Fig. 2 is the A-A sectional view of Fig. 1.

Structural representation when Fig. 3 is the utility model one side insertion key.

Fig. 4 is the B-B sectional view of Fig. 3.

Fig. 5 is the structural representations of the utility model both sides when all inserting key.

The specific embodiment

As shown in the figure, the utility model comprises left lock core body 2 and the right lock core body 3 by extension bar 1 butt joint, left side lock core body 2, the relative left lock core shaft 4 of pegging graft in the right lock core body 3, right lock core shaft 5, be provided with the cam 6 of unblanking between left side lock core body 2 and the right lock core body 3, the left slider 8 that has flange 7, right slide block 9 one sides can be installed in left lock core shaft 4 axially slidably, drive by lock core shaft in the right lock core shaft 5 and by flange 7, left slider 8, the opposite side of right slide block 9 can be arranged in the cam 6 of unblanking by flange 7 axially slidably with the driving cam 6 of unblanking, in lock core shaft, be provided with the driving groove 12 that matches with flange 7, on the cam 6 of unblanking, be provided with the interlock groove 13 that matches with flange 7,7 one-tenth of flanges on the slide block are stepped, to guarantee the reliability of interlock.The spring 10 relative with lock core shaft all axially is set in left slider 8 and right slide block 9, in left slider 8 and the right slide block 9 axially the spring 10 of setting be two, to guarantee the balance of pressure at both sides.On axis direction, flexibly connect between left slider 8 and the right slide block 9 by bearing pin 11.Under user mode, when left side key inserts, key pushes a side spring 10, under the effect of spring force, left slider 8 moves to right, flange on the left slider 87 keep with the cam 6 of unblanking on the cooperating of interlock groove 13, and the flange 7 on the right slide block 9 separates with interlock groove 13 on the cam 6 of unblanking, left slider 8 drove the cam 6 of unblanking and rotates unlatching when key drove 4 rotations of left lock core shaft, and at this moment, right slide block 9 keeps not changeing.When the right key inserts simultaneously, both sides spring 10 is simultaneously stressed, and reach balance gradually, make left slider 8 and right slide block 9 move to the centre position, flange 7 on it simultaneously with the cam 6 of unblanking on the cooperating of interlock groove 13, rotate and unblank thereby make the key on both sides and drive the cam 6 of unblanking by lock core shaft's interlock left slider 8 and 9 rotations of right slide block.Above-described embodiment is described a kind of preferred implementation that can two-sided unlatching door lock core of the utility model; 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 a kind of protection domain that can two-sided unlatching door lock core of the utility model.
