Description

A kind of novel anti-theft lock core

Technical field

The utility model relates to a kind of theftproof lock, particularly relates to a kind of novel anti-theft lock core.

Background technology

Since the reform and opening-up, the China's economic fast development, living standards of the people improve day by day, some social security problems also occurred simultaneously, and various pilferage situations happen occasionally, and have caused certain loss for the people's property.Therefore, various antitheft equipment arise at the historic moment, and the theftproof lock of selling on the market is various in style now, and function is also varied.The still cylinder lock that the lock core of existing theftproof lock generally uses, when opening, utilize the tooth that is provided with on the key that the pellet shot from a slingshot in the lock core is promoted in lock core base, when the pellet shot from a slingshot in the lock core is released fully, lock core just can freely rotate in lock core base, the dead bolt that rotation by lock core just can drive in the theftproof lock moves inward, thereby open theftproof lock, this cylinder of spring lock exists a common defective to be exactly: owing to only rely on less pellet shot from a slingshot and spring to lock their mutual rotation between lock core and lock core base, therefore its lock core is easy to the extraction by by force, as long as lock core is drawn out of, just can rotate the device of stirring that is positioned in the theftproof lock on the lock base, thereby can easily theftproof lock be opened with screwdriver or other flat partially plate instrument.

Therefore, present cylinder of spring lock structure is firm inadequately, is easier to be prized, and the pick-proof performance of theftproof lock that causes being equipped with cylinder of spring lock is not good.

Though the anti-theft lock core of various designs emerges in an endless stream, its structure setting all has certain limitation, can not satisfy the requirement of people to the latch fitting tamper-resistant function fully.

Prior art complex structure, cost height, the scope of application is little, the life-span is short, safety factor is not high.

Summary of the invention

The purpose of this utility model is for a kind of sound construction is provided, and protection is accurate, cost is low, applied widely, the life-span is long, a kind of novel anti-theft lock core with good pick-proof performance of vi have high safety.

Goal of the invention of the present utility model is achieved through the following technical solutions:

The utility model comprises lock core base, is positioned at lock core and spring that lock core base can rotate mutually, be provided with keyhole in the lock core, corresponding section on lock core and lock core base is respectively equipped with multilayer lockhole and locked groove, it is characterized in that: be provided with paired jam plate in described lockhole and the locked groove, be provided with spring between described jam plate and the jam plate or between jam plate and the locked groove, be equipped with jam plate and spring in every layer in described several layers of lockhole and the locked groove.

Lockhole and the locked groove that is arranged in lock core and the lock core base described in the utility model has six to eight layers, and described lockhole and locked groove are cuboid.

The cross section of jam plate described in the utility model is two staggered nestable two " recessed " shapes together that stretch, and spring is positioned between the jam plate of the rear end of first " recessed " shape and second " recessed " shape front end.

The cross section of jam plate described in the utility model roughly is " H " shape, and transverse presentation is divided upper and lower two ones in the middle of it, and the cross section, top is " protruding " shape, and lower section is " one " font, between the jam plate that described spring staggers relatively in bottom two.

The cross section of jam plate described in the utility model is " C " font, and described spring is positioned at " C " font jam plate outside.

Lockhole and the locked groove that is arranged in lock core and the lock core base described in the utility model has six layers, its textural association is: the cross section of described first floor jam plate is two staggered nestable two " recessed " shapes together that stretch, the cross section of described second layer jam plate is " C " font, and the cross section of described the 3rd layer of jam plate roughly is " H " shape.

Jam plate structure described in the utility model the 4th layer is identical with the jam plate structure of first floor; The jam plate structure of layer 5 is identical with the jam plate structure of the second layer; The jam plate structure of layer 6 is identical with the 3rd layer jam plate structure.

Jam plate structure described in the utility model setting can be made up arbitrarily as required, also can dispose separately, and its jam plate puts in order and also can replace mutually, and associated Key structure is meshed with the setting of jam plate structure.

The beneficial effect that the utility model adopts technique scheme to reach is:

Replace present pellet shot from a slingshot by jam plate, can improve the fastness of anti-theft lock core greatly, lockhole is arranged to different shapes with the jam plate in the locked groove, make it when unblanking, the tooth that the jam plate that has need be by on the key is with its inside extruding; The jam plate that has need be by on the key tooth with it earlier to the both sides extruding, allow its return then; The jam plate that has need push it by tooth on the key to both sides, realize that lock core and lock core base go out of lock, and finally could open theftproof lock.

It is reasonable, accurate that structure of the present utility model is provided with, external force is difficult for lock core is extracted out by force, can't rotate the device of stirring that is positioned in the theftproof lock on the lock base with screwdriver or other flat partially pull piece instrument, thereby the pick-proof performance of the theftproof lock that the utility model lock core has been installed is improved greatly, guarantee the safety of people's properties, reduced the pressure of people's public security.

The utility model design is ingenious, economical and practical, applied widely, can be installed on as required and anyly have on the article that need, and cost is low, long service life, have vast market prospect.
