Description

A kind of theftproof lock with the hiding lockhole of ring-type

Technical field

The utility model relates to a kind of theftproof lock, particularly relates to a kind of position by hiding lockhole and carries out the antitheft theftproof lock that ring-type is hidden lockhole that has.

Background technology

Theftproof lock in the middle of the prior art all is the material that utilizes intensity hardness higher basically, by the internal construction of lock core is adjusted design, prevent destroyed, on the one hand, outside lock core is directly exposed to, commit theft to the thief and to bring direct Action Target, comparing with the high property of existing destruction facility, its theftproof performance is lower, on the other hand, the theftproof lock that has has adopted the electronic anti-theft function, by some electron scannings or warning system, can remind at any time, but such theftproof lock cost height, and safety factor is not high, and application life is not long yet, maintenance trouble after going wrong.

The utility model content

The purpose of this utility model provides a kind of position that can well hide lockhole, and it is big to destroy difficulty, the theftproof lock with the hiding lockhole of ring-type simple in structure.

The purpose of this utility model realizes by following technical proposal: a kind of theftproof lock with the hiding lockhole of ring-type, comprise lock housing, lock core, key, in described lock core is wrapped in by lock housing, the strip that the front end of lock housing offers an annular snaps in through hole, strip snaps in one section hole of advancing that snaps in through hole for diameter greater than strip of through hole, the front end of key is the section of unblanking, the rear end of the section of unblanking is the columned snap section of diameter less than the section of unblanking thickness, the rear end of snap section connects the shank of the key, strip snaps in the diameter of the width of through hole greater than snap section, less than the thickness of the section of unblanking, when the snap section of key placed strip to snap in the through hole, the section of unblanking can be positioned in the lock core.

The length of described snap section is greater than the shift length after in the section of unblanking is positioned over lock core.

From architectural feature of the present utility model as can be seen, advantage of the present utility model is: simple in structure, well hidden the position at lock core place, and because tiny strip snaps in the setting of through hole, destroy the words of lock core if desired, be difficult to directly utilize instrument to destroy, afterwards can and must destroy outside lock housing, increased the difficulty of destroying, anti-theft effect is better, in addition, the strip of annular snaps in the setting of through hole, just can there be a variety of selections the position that lock core is arranged on lock housing inside, and disguised strong, safety factor is higher.
