Abstract

The utility model relates to a lock tool, which can commendably prevent other things except the suitable key of the lock from unlocking to rob and make an inserting channel of a lock hole and an inserting part of the key into non-plane circular arcs or elliptical arcs, thus making other things and the key are unable to insert completely, thereby avoiding being unlocked to rob.

Description

The circular arc passage prevents the pirate of the open lockset

Affiliated technical field

The utility model relates to a kind of novel lockset that can prevent pirate of the open.

Background technology

Now, the lockhole of all on the market locksets and key all directly extend.Such lock, the lawless person just is easy to stretch in the lockhole by stirring the pellet shot from a slingshot core of the inside with one or several slender bodies, thus the pirate of the open lockset.

Summary of the invention

Stretch into pirate of the open in the lockhole in order to overcome with slender body, the utility model can well reduce the pirate of the open phenomenon by changing the shape of lockhole and key.

The technical scheme that the utility model is taked is: the insertion portion of the passage of lockhole and key is made nonplanar circular arc or ellipse arc, the radius of curvature of different locksets is made different, cooperate groove on the key again.So, not only can not put in pirate of the open, even the key of different curvature radius can not stretch equally, so the phenomenon that can significantly reduce pirate of the open, open by mistake with slender body.

The beneficial effects of the utility model are: can prevent that other article beyond this lockset matched key from stretching in the lockhole, thereby reduce lockset greatly by pirate of the open, the probability that opens by mistake.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is a front view.

Fig. 3 is the vertical view of Fig. 2.

This product design main points only just can be expressed with three views, so omit other views.

Design main points of the present utility model are at the sweep of key and lockhole.

The sweep of lockhole shape of the present utility model and key is identical, so omit.

The specific embodiment

Among the figure, the insertion portion of key is an arc, also makes identical arc with its access opening of lock that key is supporting.To different locks, its amount of curvature is preferably made different, can also make the direction of bending left, two kinds inequality to the right.

Claims

1. the circular arc passage prevents the pirate of the open lockset, and lockhole passage and key insertion portion are made nonplanar circular arc or ellipse arc, it is characterized in that: the insertion passage of lockhole and the insertion portion of key are made the molded non-planar of same curvature.

2. lockset according to claim 1, it is characterized in that: the insertion portion of key can be made crooked left, also can make bending to the right, can also make different bending curvatures, corresponding lock is just made bending direction the same with key and curvature to lockhole.
