Abstract

The utility model relates to a key, wherein a guide locating slot is arranged on the left plugging surface and the right plugging surface of a key main body, a password sprocket hole is arranged on an upper plugging surface of the key main body, a residual side which is on the same level with the plane of the upper plugging surface is left on the password sprocket hole in the thickness direction of the key main body, one side of the guide locating slot is further provided with a special-shaped unlocking groove which is a continuous asymmetrical curved groove, the opening end of the special-shaped unlocking groove is a bellmouth, and the width of the opening end is bigger than the inner side. The key overcomes the shortcomings of rough cooperation, little password composition, weak anti-theft property and bad unlocking hand feeling of a traditional key in the prior art, and with the design, the whole inner surface of the password sprocket hole is cooperated with the contact surface of a marble in a lock core, and the key greatly improves the stability, greatly increases the variation of password composition of the key under the premise without increasing the production cost of the key almost, and has the advantages of compact cooperation with the lock core and strong anti-theft property.

Description

Key

Affiliated technical field

The utility model relates to a kind of key.

Background technology

Traditional key, on its side, be the continuous sheet close tooth of unblanking of projection, design has a guide-localization groove on the plug surface of both sides, when key inserts lock core, one group of password pellet shot from a slingshot in the lockset only is complementary with on the key the close tooth of unblanking, its cooperation is comparatively coarse, and the guide-localization groove only plays location, guide effect.Therefore not only password combination is few for above-mentioned key, and a little less than the theftproof performance, and stability is not high, and the feel of unblanking is poor.

Summary of the invention

Cooperate coarsely in order to overcome in the prior art traditional key, password combination is few, theftproof performance a little less than, the problem of the feel of unblanking difference, the utility model provides a kind of key, the compactness that cooperates of this key and lock core, stability is high, and the variation of password combination is many, and theftproof performance is strong.

The technical scheme that its technical problem that solves the utility model adopts is: on the left and right plug surface of key body the guide-localization groove is set, be provided with the password perforation on plug surface on the key body, the password perforation leaves on the thickness direction of key body and mutually concordant surplus limit, last plug surface plane.

On the following plug surface of key body, be symmetrical arranged the password perforation.

One side of guide-localization groove also is provided with the abnormity groove of unblanking, and the abnormity groove of unblanking is continuous skew curve groove.

The unblank openend of groove of abnormity is a horn mouth, and open end width is greater than inboard width.

The utility model is by above-mentioned specific design, the contact surface of pellet shot from a slingshot matches in the total inner surface of password perforation and the lock core, has improved stability greatly, combines and has also greatly increased the variation of key cipher combination with the abnormity groove of unblanking, has the compactness that cooperates with lock core, the advantage that theftproof performance is strong.

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;

The vertical view of Fig. 2 Fig. 1;

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

The specific embodiment

As shown in the figure, on the left and right plug surface of the utility model key body 1 guide-localization groove 2 is set, 2 of guide-localization grooves play location, guide effect.On plug surface 3 on the key body 1, be provided with password perforation 4, also can be symmetrical arranged password perforation 4 on the following plug surface 7 of key body 1, password perforation 4 leaves on the thickness direction of key body 1 and mutually concordant surplus limit 5, last plug surface 3 planes, also be provided with the abnormity groove 6 of unblanking in a side of guide-localization groove 2, unblank groove 6 of abnormity is continuous skew curve groove, the unblank openend of groove 2 of abnormity is a horn mouth, and open end width is greater than inboard width.The contact surface of password pellet shot from a slingshot matches in the total inner surface of password perforation 4 and the lock core, has improved stability greatly, and abnormity is unblanked, and custom-designed special-shaped pellet shot from a slingshot is used in groove 2 and the lockset lock core shaft.Unblank groove 2 and password perforation 4 of abnormity makes up mutually, increased the permutations of code of key greatly, improves theftproof performance, and the manufacturing and designing of groove 2 and password perforation 4 of unblanking of above-mentioned abnormity compared with normal key and to be increased cost of production hardly.

Claims (4)

1, a kind of key, on the left and right plug surface of key body the guide-localization groove is set, it is characterized in that being provided with password perforation (4) on the last plug surface (3) of key body (1), password perforation (4) leaves on the thickness direction of key body (1) and mutually concordant surplus limit (5), last plug surface (3) plane.

2, key according to claim 1 is characterized in that being symmetrical arranged password perforation (4) on the following plug surface (7) of key body (1).

3, key according to claim 1 and 2, a side that it is characterized in that guide-localization groove (2) also are provided with the abnormity groove (6) of unblanking, and the abnormity groove (6) of unblanking is continuous skew curve groove.
