A plurality of the lock boards need to be squeezed inwards through the teeth on a key; a plurality of lock boards need to be squeezed towards both sides first through the teeth on the key, and are returned then; a plurality of lock boards need to be squeezed towards both sides through the teeth on the key, and realize the disengaged locking of the lock core and the lock core seat when a theft-proof lock is unlocked. Finally, the theft-proof lock can be unlocked. The prizing-proof performance of a theft-proof lock which is provided with the lock core of the utility model is enhanced.

Description

A kind of lock core of theftproof lock

Technical field

The utility model relates to the technical field of theftproof lock, more particularly relates to a kind of lock core of theftproof lock.

Background technology

At present, the theftproof lock of selling on the market is various in style, function is also varied, the still cylinder lock that the lock core of its 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, number of patent application as the Chinese utility model patent of portion is 00228538, the applying date is on June 17th, 2000, and denomination of invention is a kind of cylinder of spring lock and key thereof, it include relatively turnable in, outer lock core, it is characterized in that lock core keyhole is the T type, internal cylinder is dispersed in the T of keyhole type and is distributed with the pellet shot from a slingshot hole on the direction, and the outer lock core correspondence has bullet groove, bullet groove, outer pellet shot from a slingshot is housed in the hole, internal layer pellet shot from a slingshot and spring; Internal cylinder is distributed with the pellet shot from a slingshot hole on the T of keyhole type end face, the outer lock core correspondence has bullet groove, and outer pellet shot from a slingshot, internal layer pellet shot from a slingshot and spring are housed in bullet groove, the hole.Its lock core also is a cylinder 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 with screwdriver or other flat partially plate instrument, thereby just can easily theftproof lock be opened, therefore, present cylinder of spring lock structure is firm inadequately, be easier to be prized, thereby make the pick-proof performance of the theftproof lock that cylinder of spring lock is installed not good.

The utility model content

The purpose of this utility model provides a kind of sound construction in order to solve above-mentioned deficiency exactly, has a kind of anti-theft lock core of good pick-proof performance.

The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:

A kind of anti-theft lock core, comprise lock core base, be 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, described lockhole and locked groove are cuboid, the paired jam plate that is provided with in above-mentioned lockhole that is cuboid and locked groove, spring are arranged between jam plate and the jam plate or between jam plate and the locked groove.

Described lockhole and the locked groove that is arranged in lock core and the lock core base has five to seven layers, is provided with jam plate and spring in every layer.

The cross section of described jam plate is " recessed " shape, and spring is positioned at two and is between the jam plate of " recessed " shape.

The cross section of described jam plate is " H " shape, and spring is between two jam plates that stagger relatively.

Described lockhole and the locked groove that is arranged in lock core and the lock core base has five layers, and first floor jam plate cross section is " recessed " shape, and spring is positioned at two and is between the jam plate of " recessed " shape; Second layer jam plate cross section is L-shaped, and spring is positioned at two and is " L " shape jam plate outside that is oppositely arranged; The 3rd layer jam plate structure is identical with the jam plate structure of first floor; The 4th layer of jam plate cross section is " H " shape, and spring is between two jam plates that stagger relatively; The jam plate structure of layer 5 is identical with the 4th layer jam plate structure.

The beneficial effect that the utility model adopts above-mentioned technical solution 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 theftproof lock could be opened, and the pick-proof performance of the theftproof lock that the utility model lock core has been installed is improved greatly.
