Description

Safety anti-theft lock

Technical field

The invention provides a kind of safety anti-theft lock, belong to the anti-theft locking technical field.

Background technology

Lockset is the indispensable safety precaution apparatus of department such as people's daily life and haulage vehicle, warehouse, finance security personnel.Lockset commonly used at present, its lock core is taked the cylinder type rotational structure more.For tightening security, reduce mutual opening rate, its technical measures generally concentrate on and adopt many ribs, multiple tooth key, and equipped mutually multi-faceted pellet shot from a slingshot aspect.Above-mentioned measure has obviously reduced the mutual opening rate of lockset, has stopped to pull out the possibility of pressing pellet shot from a slingshot to unblank, and has improved the theft-proof of lockset.But by anti-stealing technology measure sawed-off, that do not break, prize lock box, the drilled taking-up of lock core, because the limitation of the conventional construction form of lockset, improvement project is few at the lock bridge of lockset, and effect is very ineffective yet.The whole theft-proof of existing lockset is difficult to be improved always.

Summary of the invention

At the above-mentioned deficiency of existing lockset technology, the purpose of this invention is to provide and a kind ofly can prevent effectively that the lock bridge lock box from being prized, cut, its mutual opening rate obviously reduces, when the drilled taking-up of lock core, the also safe anti-stolen lock that can not unblank.

Above-mentioned purpose of the present invention, realize by following technical measures:

Safety anti-theft lock is made of the lock box of lock body and split, and wherein, lock body is provided with the cylinder type lock core of lock core finger by the top, has the lock entity of horizontal chamber; Be seated in the indoor lock bridge clamp that is provided with hole clipping and lock core pin-shifting hole of this transverse chambers; The lock bridge clamp contacts with the clamp back-moving spring; And the lock bridge column cap manhole appendix that leads to lock bridge clamp in the chamber on the lock entity is formed; Key can contact with the lock core finger after inserting the lock core pin-shifting hole; The lock box of split is two tuft shape box bodys that have the lock bridge column cap; Dissection type lock bridge column cap was formed a complete lock bridge column cap when split lock box closed up on two, and the lock bridge column cap coincide in the hole clipping of lock bridge clamp by lock bridge column cap manhole appendix.

The cross section of described lock bridge clamp is half elliptic.

Described lock bridge column cap is provided with two at least, is the axis equity dissection type along the lock bridge column cap.

Five kinds of orientation settings of the pellet shot from a slingshot of described lock core are the M shape, equipped M shape key with many ribs tooth post.

Two split lock boxes of safety anti-theft lock, be inlaid in door body respectively and the door limit correspondence position that is close on.When locking a door, lock body is inserted in the open cavity of two Lock with several separated loching head box-likes one-tenth.The lock bridge column cap that is provided with in the split lock box by the lock entity beam column head manhole appendix of locking, puts in the lock bridge clamp, and forces the compression displacement earlier of lock bridge clamp back-moving spring, and part resets and passes the lock bridge clamp and block the lock bridge column cap that puts in then, finishes the process of locking a door.

The structure of safety anti-theft lock can accomplish easily that lock body embeds in the cavity of split lock box, perhaps at least lock body and split lock box to expose side concordant, realize door lock and be on the plane by the doorframe of setting-in, a door limit.Do not have outstanding corner, corner angle, effectively avoided the sort of because of picking lock body, picking lock box, twist off or thievery that sawed-off lock bridge causes takes place.Take to bore lock core as for the sort of.Take out lock core, so pull out lock bridge, the gimmick of the theft of implementing to open the door because the lock bridge clamp is compressed the spring push-tight, non-lock core finger is difficult to implement DIP and moves, therefore, safety anti-theft lock has and prevents because of boring the function that lock core is unblanked.The mode of unblanking of safety anti-theft lock is the same with existing lockset, as long as key is inserted lock core hole, reverses lock core, and lock core top finger is pushed the lock bridge clamp open, it is withdrawed from block lock bridge column cap position, just can take out lock body, implements to unblank to open the door action.

The specific embodiment

Safety anti-theft lock is made of the lock box 1 of lock body 2 and split.Wherein, lock body 2 comprises cylinder type lock core 4, has the lock entity of horizontal chamber 9, is seated in the lock bridge clamp 3 in this horizontal chamber 9, leads to the lock bridge column cap manhole appendix 5 of lock bridge clamp 3 in the chamber on the back-moving spring 15 of clamp 3 and the lock entity.The lock box of split is tuft shape box body that two bottom sides have lock bridge column cap 6.

In the present embodiment, lock bridge clamp 3 is that two cross sections are the half elliptic clamp, and clamp 3 is provided with the hole clipping 16 of lock bridge column cap 6, and lock core pin-shifting hole 7.The clamp folding position in two half elliptic cross sections is by lock core finger 11 and 15 lockings of clamp back-moving spring.Five kinds of orientation settings of the pellet shot from a slingshot of lock core are the M shape, equipped M shape key 14 with many ribs tooth post.Be fitted to the different pit of the depth 13 with pellet shot from a slingshot on the key bit post.8 is marble spring, and 12 is M shape keyhole, and 10 is the lock box screw hole.

In the present embodiment, lock bridge column cap 6 is provided with two at least, and the axis equity dissection type for along the lock bridge column cap respectively is provided with half on two split lock boxes, and when two split lock boxes closed up, dissection type lock bridge column cap was formed a complete lock bridge column cap 6.
