Description
Technical field
What the present invention relates to is a kind of device of mechanical lock technical field, specifically is lock core and key thereof that a kind of diplopore involves rotation push and block formula cylinder lock.
Background technology
The motion process of a most widely used letter lock of daily family is roughly key and inserts lockhole, utilize the profile of tooth of key will descend pellet shot from a slingshot (pellet shot from a slingshot partly is divided into two parts up and down) up to push up and make the upper end of inner 6 to 8 pellets shot from a slingshot to align simultaneously, no longer include pellet shot from a slingshot its external lock cover is carried out screens, thereby can realize the rotation of lock core, realize the overall process of unblanking at last.Yet its defective also is fairly obvious.Only rely on the difference and the agreeing with of shaped as key bit of pellet shot from a slingshot length size to realize cryptographic function, security performance is single.More common simple broken lock process: at first, one thin, little steel disc are stretched into lock core, itself and lock core are not relatively moved.Rotational lock core makes lock core that little moving be taken place gently.Then, stretch into another tiny rigid objects, stir hoodle.Hoodle can be moved, because the little of lock core moves at the beginning, hoodle can stop card at correct position.At last, after all hoodles were moved flat, lock core just can be opened.Can find clearly that single hole and single cryptographic function make its security performance very low.
Find that through retrieval the lockset industry is a field that product category is various always to prior art.As the utility of safe antitheft, must update technically, product is weeded out the old and bring forth the new, could resist the continual renovation of separating lock tool and other technical unlocking method.In the mechanical lock that the most generally uses, there are a letter lock, cross lock, double flute lock, two-sided flat core lock, cylindrical core steel marble lock, steel magnetic to mix shape cylinder lock, Lock with inside lock and lock external lock or the like.
Although but the contour structures difference is very big, the lock core internal construction also becomes increasingly complex, but use special instrument or take technical method can open equally, its reason is that the know-why of most mechanical locks there is no the difference of essence, just one by simply developing into loaded down with trivial details theory, mutual restriction ability between the pellet shot from a slingshot is low, thereby can't reach the effect that precautionary technology is unblanked.
Summary of the invention
The present invention is directed to the prior art above shortcomings, provide a kind of diplopore to involve the lock core and the key thereof of rotation push and block formula cylinder lock, simple in structure, easy to manufacture, volume is less, includes the defencive function of baffle plate, has improved the security performance of lockset greatly.
The present invention is achieved by the following technical solutions:
