Description

Lock core and the key matching with it

Technical field

The invention belongs to a kind of lockset, the key that especially relates to a kind of lock core and match with it.

Background technology

At present, on known key piece for the tooth groove of unblanking along lineal layout, and in lock core, in axial direction offer for inserting the straight line key of key, key matches with lock core after inserting, opened lock.Existing lock core comprises fixed body and rotary body, along the radial direction of the rotary body key of core, offers a series of hoodles hole, and the hoodle hole on the corresponding core rotor in hoodle hole on fixed body, is equipped with a pair of hoodle and a spring in corresponding hoodle hole.When key straight line inserts after the key of core, key is stirred the hoodle of core, makes in a hoodle in every pair of hoodle in the corresponding hole rotor in core, in the fixed body of another hoodle in core, thereby the rotor of core can be rotated, and lock is opened.But, because key linearly arranges, thereby easily by iron wire, tinfoil or master key or other, do not adopted the improper modes such as original key to open, safety factor is not high.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, the lock core that security performance is high and the key matching with it.

According to an aspect of the present invention, a kind of lock core is provided, comprise fixed body and be located at the rotary body in fixed body, rotary body comprises main shaft and is fixed on the pipe in main shaft outside, main shaft is provided with conveyor screw, on pipe, offer through hole, in fixed body, offer installing hole, the corresponding setting of spirochetal groove of through hole and installing hole and main shaft, in groove, be provided with cylinder, through hole, the second hoodle that is provided with the first hoodle in installing hole and spirochetal groove and matches with the first hoodle, the first hoodle is positioned at spirochetal groove and through hole, the second hoodle is positioned at through hole and installing hole, in installing hole, be provided with for compressing the spring of the second hoodle.

The invention has the beneficial effects as follows: because the rotary body of lock core comprises main shaft, main shaft is provided with conveyor screw, and the first hoodle and the second hoodle are arranged in the installing hole on spirochetal groove, through hole and fixed body.Therefore, when adopting iron wire or tinfoil etc. to unblank along the axis direction insertion of rotary body, the first hoodle is stopped by the conveyor screw bossing on main shaft, cannot normally insert, thereby the first hoodle and the second hoodle are locked rotary body, and cannot rotate, effectively avoided adopting illegal mode to unblank, improved the security performance of lockset.Meanwhile, in groove, be provided with cylinder, can prevent entering of the software unlocking tools such as tinfoil, prevent the suction to the first hoodle and the second hoodle such as tinfoil, strengthened the safety of lock core.

In some embodiments, lock core can also comprise case and cap, and case is located at the outside of fixed body, and cap is fixed on fixed body upper lock tongue place one side.Thus, be provided with case and cap, facilitate the fixing of this lock core and install, meanwhile, also further strengthened the soundness of lock core, improved safety.

In some embodiments, one end of cylinder is fixed on pipe, the bottom land of other end contact groove.Thus, facilitate the installation of cylinder, easy to use.

A kind of key matching with lock core is provided according to an aspect of the present invention, has comprised key piece, in the shape of a spiral, the conveyor screw on key piece and main shaft matches key piece, offers the gap matching with cylinder on key piece, and key piece is run through in gap.Thus, key of the present invention is when unblanking, the helical form of key piece matches with the conveyor screw on the main shaft of lock core, thereby, the first hoodle that key piece promotion is positioned at spirochetal groove and through hole moves to the second hoodle direction, drive again the second hoodle to move, removed the locking of the second hoodle to rotary body, the unlatching of convenient lock.Meanwhile, match with the cylinder on lock core in the gap on key piece, the unlatching of convenient lock.

In some embodiments, the dual-side of key piece all can be provided with stiffened edge.Thus, be provided with the steadiness that stiffened edge can strengthen key, increase the application life of key.

In some embodiments, the inner side of key piece can be provided with the teeth groove being arranged in order.Thus, the different depth of teeth groove assembles the first hoodle and second hoodle of the size that adapts, thereby, make the corresponding specifically key of specific lock; Meanwhile, improved the difficulty copying of key, avoided key when losing, other people carry out copying of key, have increased the safety of using.

In some embodiments, teeth groove can be deep-slotted chip breaker.Thus, improved the complexity of key in manufacture process, effectively prevented that other people from copying.

In some embodiments, teeth groove can be V-shaped groove.Thus, improved the complexity of key in manufacture process, effectively prevented that other people from copying.
