Abstract

The utility model relates to an anti-theft lock which is theft-proofing by hiding the position of a lock hole; the utility model aims at providing an anti-theft lock which can well hide the position of the lock hole, and has high damaging difficulty and simple structure; the purposes of the utility model are realized by adopting the following technical proposal: the anti-theft lock comprises a lock case, a lock cylinder and a key; the front end of the key is an unlocking section, the rear end of the unlocking section is a clamping section of which the thickness is thinner than the unlocking section, and the rear end of the clamping section is connected with a key handle; the anti-theft lock is mainly applied to the anti-theft door lock and other devices which need the anti-theft lock.

Description

A kind of theftproof lock

Technical field

The utility model relates to a kind of lock, particularly relates to a kind of position by hiding lockhole and carries out antitheft theftproof lock.

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, destroys big, the simple in structure theftproof lock of difficulty.

The purpose of this utility model realizes by following technical proposal: a kind of theftproof lock, comprise lock housing, and lock core, key, the front end of key is the section of unblanking, and the rear end of the section of unblanking is the thickness snap section thinner than the section of unblanking, and the rear end of snap section connects the shank of the key.

In described lock core is wrapped in by lock housing, the front end of lock housing offers one and enters the hole, entering the hole offers a strip and snaps in through hole on the direction of lock core, strip snaps in the thickness of the width of through hole greater than snap section, thickness less than 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 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.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Preferred embodiment

A kind of theftproof lock as depicted in figs. 1 and 2 comprises lock housing 1, lock core 2, and key 3, the front end of key 3 is the section of unblanking 4, the rear end of the section of unblanking 4 the be thickness snap section 5 thinner than the section of unblanking 4, the rear end connection the shank of the key 6 of snap section 5.

In described lock core 2 is wrapped in by lock housing 1, the front end of lock housing 1 offers one and enters hole 7, entering hole 7 offers a strip and snaps in through hole 8 on the direction of lock core 2, strip snaps in the thickness of the width of through hole 8 greater than snap section 5, thickness less than the section of unblanking 4, when the snap section 5 of key 3 placed strip to snap in the through hole 8, the section of unblanking 4 can be positioned in the lock core 2.

The length of described snap section 5 is greater than the shift length after in the section of unblanking 4 is positioned over lock core 2.

Lock housing 1 of the present utility model is wrapped up lock core 2 fully, front end offer one be used to put into key 3 enter hole 7, and snap in through hole 8 by a tiny strip, be used for putting into of key 3, and be two parts with the shaped design of key 3, the section of unblanking of front end 4 is used to unblank, can be positioned in the lock core 2, the snap section 5 of rear end is set to the relatively thinner structure of thickness, just can snap in through hole 8 by strip and make the section of unblanking 4 arrive the position of lock cores 2 from entering hole 7, and the length of snap section 5 enough the section of unblanking 4 enter into lock core 2 inside and unblank.Can be undertaken better antitheft by higher lock housing 1 front end of design thickness.The utility model is simple in structure, the security performance height.
