Description

A kind of novel anti-burglar lock and key thereof

Technical field

The utility model belongs to lock technology field, specifically, relates to a kind of novel anti-burglar lock and key thereof.

Background technology

Lock is the important burglary-resisting installation that people protect property in daily life, and its safe antitheft is primary.

The existing pellet class lock generally used, its structure is the object adopting the diverse location state of cylindrical billiard in marble hole of length different designs to reach locking and open.

At nominal conditions, when unblanking with original key, key inserts lock core pushing tow pellet, make the outer end face of pellet all equal with lock core cylindrical outer surface, the rotation of key just can make lock core in the lock core hole of shell, drive pellet to do left and right synchronous axial system, and stirs dead bolt opened lock by driver blade.

But more existing unlocking tools can easier stretch in the lockhole of this type of lockset lock core, by the lock pearl jack-up in core body to appropriate location, thus lock is opened, so the mechanical lock theftproof performance of prior art is poor by rotation core body.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of novel anti-burglar lock and key thereof, comprise shell, lock core, pellet and keyhole, described shell is provided with lock groove, the corresponding described lock groove of described lock core is provided with lock groove, lock is provided with in described lock groove, some pellets are also provided with in described lock core, the corresponding described lock in the side of described pellet is provided with groove away from the side of described lock groove, the corresponding described lock core inner surface of described lock is provided with breach, lock spring is provided with in described breach, the corresponding described lock core inner surface in upper end of described pellet is provided with marble spring, described lock core is provided with the keyhole of accommodating key in the lower end of described pellet, when theftproof lock is in locking state, the lower end of described pellet is all positioned at pellet stop surfaces, described pellet comprises common spring and contacts pellet, when theftproof lock be in lock or unlocking condition time, the lower end of described contact pellet is positioned at pellet stop surfaces all the time, the corresponding described contact pellet of described key is provided with through hole, when theftproof lock is in unlocking condition, the lower end of common spring is positioned at above described key, at least one common spring is provided with away from the side of the keyhole of described lock core at described contact pellet.

Further, described groove is v-depression.

Further, the lower end of described pellet is V-arrangement or semicircle.

Further, described lock is square, and the corresponding described lock of described lock groove is square groove.

Compared with prior art, the beneficial effects of the utility model are:

A kind of novel anti-burglar lock described in the utility model and key thereof, no matter lock core be in lock or unlocking condition time, the lower end of contact pellet is all in pellet stop surfaces, once moving contact pellet, contact pellet is just in locking state, thus makes whole lock core be in locking state.If press the direction of keyhole entrance to the inside for sequentially arranging, the design of contact pellet is being come position above, making to contacting after pellet also has some common spring.Utilizing picklock picking lock, when attempting to open contact pellet common spring below, picklock must first will contact pellet jack-up, makes lock move to the lock groove of lock core shell and enter lock groove, makes and be all in the state of locking to whole lock core.
