Abstract

The utility model relates to a novel key which consists of a key handle and a key body. The two ends of the key body have symmetrical tooth matching with a lock core marble. The two sides of the key body have symmetrical convex parts, which form a whole with the key body and extend from the root of the key body to the front end of the key body. Due to the structural improvement of the key, the stability, conjugation and anti-theft property of the key are further improved.

Description

A kind of novel key

Technical field

The utility model relates to a kind of key, particularly relates to a kind of key with better steadiness, conformability and theftproof.

Background technology

At present, common employed key all is to have on key billet together or the twice groove, and this groove matches with lock core and carries out locking or unlatching.This traditional key has some shortcomings, for example because the key face that matches with lock core is provided with groove, makes the steadiness of key descend, and brings certain influence to conformability; In addition, this key only needs its key billet is just simply processed and can be obtained on general bitting machine, brings negative influence so also for the theftproof of key.

Summary of the invention

The purpose of this utility model overcomes the existing existing shortcoming of key exactly, and a kind of novel key is provided, and by improving the structure of key, thereby further improves steadiness, conformability and the theftproof of key.

The purpose of this utility model realizes by following technical proposals, key case spatula handle of the present utility model and key body two parts constitute, the profile of tooth that matches with lock core marble that symmetry is arranged on the both ends of the surface of key body, the protuberance of symmetry is arranged on the two sides of key body, and this protuberance and key body are one and the front end that always extends to the key body from the root of key body.

Because the symmetrical protuberance on the key body does not have groove, and is to form by punch process, has so just strengthened the steadiness and the theftproof of key integral body.The key structural reform that constitutes with this form has become the mode that cooperates with lock core and has made it possible to be convenient to be properly inserted in the lock core, thereby has improved the conformability of key.

The specific embodiment

Further describe structure of the present utility model below in conjunction with accompanying drawing, making has more deep understanding to the purpose of this utility model, structure and its advantage;

Referring to accompanying drawing 1 and Fig. 2, key case spatula handle 1 of the present utility model and key body 3 two parts constitute, the profile of tooth that matches with lock core marble (as shown in the figure) that symmetry is arranged on the both ends of the surface of key body 3, the protuberance 2 that symmetry is arranged on the two sides of key body, this protuberance 2 is one and the front end that always extends the key body from the root of key body 3 with key body 3.

Claims (1)

1, a kind of novel key, including the shank of the key (1) and key body (3) two parts constitutes, the profile of tooth that matches with lock core marble that symmetry is arranged on the both ends of the surface of key body (3), it is characterized in that having on the two sides of key body (3) protuberance (2) of symmetry, protuberance (2) and key body (3) are for one and extend to the front end of key body from the root of key body (3) always.
