Description
Technical field
The utility model relates to a kind of theftproof lock, particularly relates to the theftproof lock that a kind of open keyhole is the arc lockhole.
Background technology
Theftproof lock in the middle of the prior art all is directly to put in the open keyhole by key basically, the shape of mode of putting into or perhaps lockhole and key all is a rectilinear direction, unblank by screw key or other modes, and open keyhole is bigger, can unblank by little hard system article such as iron wires, the theft mode is simple and technology content that unblank is not high, is easy to reaching the purpose of committing theft, defectiveness on the anti-theft effect inside the time faster.
The utility model content
The purpose of this utility model provide a kind of open keyhole and key all be arc and also quantity can be one or more theftproof locks.
The purpose of this utility model realizes by following technical proposal: a kind of theftproof lock of arc lockhole, comprise lock, lockhole and key, and described lockhole is that arc enters the hole, key is the arc shape with the lockhole form fit.
The hole direction of advancing of described lockhole is vertical with the face of lock.
The hole direction of advancing of described lockhole is that the angle that the face with lock forms is acute angle or obtuse angle.
Described lockhole can be one, also can be a plurality of, and simultaneously the quantity with the key of lockhole coupling and lockhole is consistent.
From architectural feature of the present utility model as can be seen, advantage of the present utility model is: open keyhole can be done camber, have only the key of arc to unblank, and the shape of lockhole is random with advancing the hole direction, by direct observation is to know its inside structure of unblanking, and a plurality of lockholes can be set under special circumstances and be equipped with many keys, theftproof performance is better, commit theft molecule except destroying lock body, can't unblank with other article by lockhole, use safer reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Wherein Reference numeral 1 is that lock 2 is that key 3 is lockholes
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Preferred embodiment
The theftproof lock of a kind of arc lockhole as shown in Figure 1 comprises lock 1, lockhole 3 and key 2, and described lockhole 3 is for arc enters the hole, and key 2 is the arc shape with lockhole 3 form fit.
The hole direction of advancing of described lockhole 3 is vertical with the face of lock 1.
The hole direction of advancing of described lockhole 3 is that the angle that forms with lock 1 face is acute angle or obtuse angle.
Described lockhole 3 can be one, also can be a plurality of, and is consistent with the quantity of lockhole 3 with the key 2 of lockhole 3 couplings simultaneously.
