Abstract

The utility model relates to an anti-theft lock, comprising a lock and a key. The lock is composed of a lock body with a lock core, and a lock handle, and the center of the lock core is a keyhole. The anti-theft lock is characterized in that an anti-drilled sheath is arranged on the upper side of the vertical lock core, and the shape of the anti-drilled sheath is in a * shape or in a round bucket shape. The key extends into the lock core, the opening end of the key is in a bend shape corresponding with a key handle, and the opening end and the key handle form an intersection angle of 70 DEG-150 DEG. The length that the height of the anti-drilled sheath of the upper side of the lock body is higher than the key opening end is 2-5 mm. Due to the fact that the anti-drilled sheath is arranged on the upper side of the lock core, and therefore, an electric drill or a steel wimble destroying the lock core through the keyhole can be efficiently prevented. The anti-theft lock has simple structure, convenient use, safety, firmness, and theft efficient preventing.

Description

Lock

Technical field

The utility model relates to a kind of lockset, particularly a kind of lock.

Background technology

At present, lock commonly used is made of lock body that has lock core and shank of the key usually, and lock core then is the weakest position of lockset anti-destructive, can make lock lose due function easily by destroying lock core.Existing a kind of anti-drill lock of protecting lock core adds a rotatable sheet metal on lock core keyhole, the hole that has on it is identical with keyhole; But perforate makes outside the keyhole of lock core is exposed to equally, thereby lock core and keyhole still subject to the destruction of electric drill or steel pricker, do not open lock even bore the picking lock core, also can because of keyhole and lock core is impaired causes a whole set of lockset to scrap.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point, effectively protects the key position lock core of lockset, for market provides a kind of safety firm lock.

The technical scheme that the utility model adopted is for achieving the above object: this lock comprises lock ﹠ key, and lock is made of lock body that has lock core and shank of the key, and the lock core center is a keyhole, it is characterized in that vertical lock core top is provided with anti-drilling sheath, and its shape is

Shape or to drum shape, key stretches into the relative the shank of the key of lock core opening end and is bending, both form angle is 70 °～150 °, the height of the anti-drilling sheath of lock body top is higher than the length 2～5mm of key operated end.

Described anti-drilling jacket thickness is 2～5mm.

Described anti-drilling sheath is made Shape, its link can adopt securing member to be directly fixed on the both sides of lock body upper surface lock core.

Described anti-drilling sheath is made Shape, its link also can be fixed in the shank of the key place of lock body soffit.

Described anti-drilling sheath is made to drum shape, and link can adopt securing member to be directly fixed on the lock body outside, is provided with perforate to anti-drilling sheath one side of drum shape.

The utility model has the advantages that: anti-drilling sheath is set above the lock core of lock body, can prevents that electric drill or steel pricker from destroying lock core by keyhole.This lock structure is simple, easy to use, safety firmly, effectively antitheft.
