Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes a key according to an embodiment of the present invention with reference to fig. 1 to 5, including the key body 1, the rear end surface of the key body 1 is provided with the first positioning groove 101, the front end surface of the key body 1 is provided with at least one third inclined groove 104, the inner wall surface of the third inclined groove 104 is provided with the first concave position 1041, the rear end surface of the key body 1 is provided with at least one second inclined groove 102, and the inner wall surface of the second inclined groove 102 is provided with the second concave position 1021. This structure utilizes being equipped with third slant groove 104 and second slant groove 102 on the key body 1 to increase the preparation degree of difficulty, lets current system key equipment can't make this key body, promotes the theftproof and is difficult to imitate the effect.

The utility model discloses a, still be equipped with protruding position 103 on the key body 1. At least two inclined planes are arranged in the third inclined groove 104 and are connected through an arc surface, so that the manufacturing difficulty is improved, a master key cannot be opened, and the anti-theft effect is improved; the third oblique groove 104 and the second oblique groove 102 have an inclination of 45 degrees to 60 degrees, and the first positioning groove 101 has an inclination of 45 degrees to 60 degrees, so that the manufacturing difficulty is improved, the first positioning groove can be matched with the lock cylinder shell 2, and multiple anti-theft effects are achieved.

The utility model also discloses an anti-theft lock with supporting use of above-mentioned key, including lock core housing 2 and lock core 3, lock core 3 is arranged in lock core housing 2, and the one end of lock core 3 is connected with locking piece 4, is equipped with on the lock core 3 to stir slant groove 301, stirs the supporting above-mentioned technical scheme of installing in slant groove 301 the key, be equipped with at least one through-hole 201 on the lock core housing 2, through-hole 201 is equipped with first spring 202, and first spring 202 is connected with lock post 203, is equipped with in the lock core 3 and promotes post 302, promotes post 302 and lock post 203 and contacts, promotes post 302 and arranges second slant inslot 102 respectively in.

When the key is used, the key body 1 is arranged in the lock cylinder shell 2, when the second oblique groove 102 of the key body 1 corresponds to the poking oblique groove 301, the first spring 202 pushes the lock cylinder 203 to move, so that one end of the push cylinder 302 in the through hole 201 is arranged in the second oblique groove 102, the surface of the lock cylinder 3 at the other end of the push cylinder 302 is kept flat, and the lock cylinder 3 can rotate.

If the second inclined groove 102 does not correspond to the shifting inclined groove 301, one end of the pushing column 302 cannot be placed in the second inclined groove 102, so that the lock cylinder shell 2 is in a locked state, the lock cylinder 3 cannot rotate, and an effective anti-theft effect is achieved.

Wherein stir the oblique groove 301 and be located 3 interior nonlinear settings of lock core, can't observe the circumstances of stirring oblique groove 301 from the jack of lock core 3 in the external world, the current omnipotent key can't implement the lock core inflection and warp to implement simultaneously the adjustment in a plurality of stir oblique grooves 301 and promote post 302 positions, finally be difficult to open the lock core, distinguish lock core and key integrated configuration in the past, play effective theftproof effect.

Surface department of lock core 3 is equipped with lock core guide way 303, is equipped with second spring 205 in the lock core casing 2, and second spring 205 is connected with guide post 204, and guide post 204 is arranged in lock core guide way 303. The lock cylinder guide groove 303 exerts multiple anti-theft effects and needs to be

In addition, the convex portion 103 is disposed at the guide pillar 204. When the inclined groove is stirred to be matched with the guide column, the connection between the lock cylinder shell 2 and the lock cylinder 3 is increased, the situation that the lock is forcibly opened due to the fact that the lock is implemented by only relying on the pushing column 302 is avoided, and the integral rigidity is further improved.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
