Description

Dual anti-theft lock

Technical field

The utility model relates to a kind of lockset, especially a kind of dual anti-theft lock.

Background technology

Antitheft sylinder commercially available at present and that people use all is the pellet shot from a slingshot holes that are in vertical distribution by lock housing, lock core, lock core piece, interior lock bolt and many groups and lock core center line, be provided with main pellet shot from a slingshot in the pellet shot from a slingshot hole, secondary pellet shot from a slingshot and spring, the key that needs only when unblanking the first wife inserts lock core hole, by key bit, main pellet shot from a slingshot is pressed down, make slit and lock core between major and minor pellet shot from a slingshot become parallel lines with slit between lock housing, get final product rotational lock core, lock is opened.Because the lock of this structure is very easily opened by master key, by annotating press pump, screw rod, nut, ultrathin high tenacity rubber case, draw pin and key piece and form the master key of one, by drawing pin rubber case is delivered in the lock core, injected high pressure gas or liquid, pellet shot from a slingshot all is pressed in the lock housing pellet shot from a slingshot hole, cause lock core free to rotate, and lock is opened, thereby said structure lock theftproof performance is poor, safety factor is little.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of theftproof performance good, safe dual anti-theft lock.The purpose of this utility model realizes by following technical proposals, the utility model comprises lock housing, lock core, the lock core piece, the lock housing pellet shot from a slingshot hole that interior lock bolt and many groups and lock core center line are in vertical distribution, lock core marble hole, be provided with main pellet shot from a slingshot in the pellet shot from a slingshot hole, secondary pellet shot from a slingshot and spring, in the end one group of pellet shot from a slingshot hole side is set up the lock pellet shot from a slingshot hole vertical with the pellet shot from a slingshot hole, the lock pellet shot from a slingshot is provided with the main pellet shot from a slingshot of lock in the hole, lock secondary pellet shot from a slingshot and lock spring, and the lock collar of setting up a band pellet shot from a slingshot hole, lock collar is fixedlyed connected with lock core and lock core piece, and last is arranged secondary pellet shot from a slingshot and is provided with a groove that matches with lock main pellet shot from a slingshot end.

Compared with prior art, the utility model theftproof performance is good, because when inserting original key to lock core, main pellet shot from a slingshot is subjected to the extruding of original key upper raised teeth, main pellet shot from a slingshot retreats on lock core and the lock housing slit, secondary pellet shot from a slingshot retreats under lock core and the lock housing slit, the gap that reaches between main pellet shot from a slingshot and the secondary pellet shot from a slingshot becomes parallel lines with slit between lock core and the lock housing, last groove of arranging on the secondary pellet shot from a slingshot is just aimed at the main pellet shot from a slingshot of lock, lock the elastic force that main pellet shot from a slingshot is subjected to locking spring, lock the groove that main pellet shot from a slingshot salient point enters secondary pellet shot from a slingshot, gap between main pellet shot from a slingshot of lock and the secondary pellet shot from a slingshot of lock is remained on the same parallel lines with slit between lock housing and lock collar, rotational lock core, lock collar is through the lock housing slit, also rotate in the gap of locking between main pellet shot from a slingshot and the secondary pellet shot from a slingshot of lock, and rotate drive internal lock bolt mechanism by the lock core piece and open lock body.When master key injects lock core, ultrathin rubber case is subjected to annotating the strong or hydraulic pressure of air pressure of press pump injection, expand in the four sides, every group of master's pellet shot from a slingshot and secondary pellet shot from a slingshot push in lock housing, every group of major and minor pellet shot from a slingshot all is depressed in the lock housing, there is not pellet shot from a slingshot in the lock core, last groove of arranging secondary pellet shot from a slingshot will surmount the main pellet shot from a slingshot of lock, the gap of locking between main pellet shot from a slingshot and the secondary pellet shot from a slingshot of lock will misplace with lock collar, lock main pellet shot from a slingshot and will block the lock collar hole, can not rotate to reach lock collar, lock core, lock core piece, and the purpose that prevents to open latch mechanism.

Owing to adopt such scheme, can prevent that the robber from using master key to open lock and stealing crime, lock a door in the theftproof lock and adopt the structure that lock is arranged in the lock, simple in structure, be fit to each model spring type lock repacking.
