Description

A kind of double rows of teeth lock and key

Technical field

The utility model relates to a kind of cylinder lock, particularly a kind of double rows of teeth lock and key.

Background technology

Cylinder lock of the prior art, the hoodle of its lock core only are arranged on key concavo-convex mouthful, so led into by other object easily hoodle are risen, and reaching the purpose of unlatching, so anti-theft feature is poor.So be badly in need of developing strong cylinder lock of a kind of anti-theft feature and key.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned prior art, and a kind of double rows of teeth lock and key are provided

The technical scheme taked of the utility model is to achieve these goals: a kind of key, comprise handle portion and the open portion that stretches out and form by handle portion, the centre of the single side face that the open portion of described key and lock gall match is provided with groove, and the two edges of single side face respectively are provided with the convex and concave teeth hole of row's symmetry along its center line.

A kind of double rows of teeth lock, comprise inner lock gall and be located at its outer lock gall cover, described lock gall is provided with described key and convex and concave teeth and cheats corresponding key groove hole, also be provided with the hoodle hole of vertical perforation on the described lock gall with key groove hole, the hoodle hole is just in time dropped in the groove of described key hoodle placed within, and it is bigger that the diameter of hoodle is compared the spacing of the groove in the middle of the described key; The position of corresponding hoodle is provided with spring eye on the wall of corresponding described lock gall cover, is provided with spring in it, and the lock gall on the top of spring puts and is provided with mounting.

Hoodle in the lock gall described in the utility model is arranged in the groove of centre of described key, the separation that the diameter of described hoodle is compared in the middle of the described key is bigger, when opening, the convex and concave teeth of described key hole can be blocked hoodle simultaneously, upwards rises the purpose that just can reach unlatching.If when having other object to enter into key groove hole in the lock gall, will be separated, hoodle can not be risen, to reach the purpose that prevents technical unlocking by the key of front hole tongue and groove.

The beneficial effects of the utility model are: compared to existing technology, the utlity model has good theftproof performance.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

A kind of key 1 shown in Fig. 1-2, comprise handle portion and the open portion that stretches out and form by handle portion, the centre of the single side face that the open portion of described key 1 and lock gall 5 match is provided with groove, and the two edges of single side face respectively are provided with the convex and concave teeth hole 7 of row's symmetry along its center line.

A kind of double rows of teeth lock shown in Fig. 1-2, comprise inner lock gall 5 and be located at its outer lock gall cover 8, described lock gall 5 is provided with described key and convex and concave teeth and cheats 7 corresponding key groove holes 6, also be provided with hoodle hole on the described lock gall 5 with key groove hole 6 vertical perforations, the hoodle hole is just in time dropped in the groove of described key hoodle placed within 2, and it is bigger that the diameter of hoodle 2 is compared the spacing of the groove in the middle of the described key 1; The position of corresponding hoodle 2 is provided with spring eye on the wall of corresponding described lock gall cover 8, is provided with spring 3 in it, and the lock gall cover 8 on the top of spring 3 is provided with mounting 4.

As shown in Figure 3-4, hoodles 2 in the lock gall described in the utility model 5 are arranged in the groove of centre of described key 1, the separation that the diameter of described hoodle 2 is compared in the middle of the described key 1 is bigger, when opening, the convex and concave teeth hole 7 of described key 1 can be blocked hoodle 2 simultaneously, upwards rises the purpose that just can reach unlatching.If when having other object to enter into key groove hole 6 in the lock gall 5, will be separated by the key of front hole tongue and groove, hoodle 2 can not be risen, reach the purpose that prevents technical unlocking.

Therefore, the utlity model has good theftproof performance.

Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
