Abstract

The invention discloses a mechanical lock core, which belongs to the field of a mechanical lock. The mechanical lock core comprises a square lock hole block, a lock core seat, an elastic sheet, a press sheet, a slide sheet, a rotating shaft and a clutch structure, wherein the clutch structure comprises a fixing block, a gear, a cam and a head end joint. The invention also discloses a lock adopting the mechanical lock core. A matched structure of the press sheet, the elastic sheet and the slide sheet is adopted, in addition, the whole solid-state lock core adopts the built-in sealed design for enabling a key not to rotate the lock core, the lock can only be unlocked through using a correct key, after the key is inserted into the lock hole, the lock can be unlocked through using a press handle pull handle matched with a lock body of the lock core without rotating the key, the existing traditional staggered unlocking and the lock picking can be avoided, and the safety is lock is greatly improved.

Description

A kind of mechanical lock and use the lock of this lock core

Technical field

The present invention relates to a kind of lockset, particularly a kind of mechanical lock and use the lock of this lock core.

Background technology

Mechanical lock refers to that generally lock body does not have electro-motor, is different from the electronic lock that motor is arranged in the lock, and as the lock of swiping the card in the hotel, mechanical lock all need insert key in lockhole, and rotates key and just can open.The lock core base that is provided with rotary lockhole axle in the lock core of this lock and can not rotates, side in the lockhole is provided with a row or multi-row pellet shot from a slingshot and other blade type shell fragment, there is lock the pellet shot from a slingshot back, there is spring on top, lock back, under locking state, lock is stuck under the elastic force effect of spring and is stuck between lock core base and the lockhole axle.After a key inserts lockhole, concavo-convex compressing pellet shot from a slingshot on the key, pellet shot from a slingshot promotes lock, the lock pressuring spring also is retracted in the lock core base fully, this moment, the lockhole axle can be with key turns, the lockhole axle rotates and drives the cam that is arranged on the axle, and cam rotates dead bolt is drawn back, and unblanks thereby finish normally.

The existing mechanical lock, because its fault of construction, especially the lockhole axle can rotate, its safety is relatively poor, usually can use prior art dislocation unlocking method to unblank, and does not namely need key to unblank.This method for unlocking of key that do not need is: skilled unlocking, utilize small pin for the case to scratch out following left or right compressing pellet shot from a slingshot or blade profile shell fragment at the iron with each shape of self-control exactly, because of the reason of while small pin for the case with some power, when all pellets shot from a slingshot or blade type shell fragment by iron collude when being urged to misalignment position with regard to this to so-called branch art a kind of utilize existing all utilize key to come a kind of dislocation unlocking method of defective of the power transmission shaft of drive lock in-core) wait or use other distinct methods to be a kind of unified address being to reach the purpose that misplaces and open lock.Usually use by " small pin for the case " and " hook ", insert in the lockhole with " small pin for the case " earlier, use " hook " that pellet shot from a slingshot is pushed up in lock then, and rotate small pin for the case simultaneously, because the lockhole axle is cylindric, and lock is not retracted in the lock core base fully, therefore the rotation meeting of lockhole axle pins lock, at this moment, use again " hook " with each pellet shot from a slingshot to will heading in the lock, thereby reach the purpose of finally unblanking.In addition, present picking lock is generally taked rotational lock core by force, and lock is fractureed, and rotational lock core is unblanked then.

Summary of the invention

One of goal of the invention of the present invention is: at the above-mentioned problem that does not adopt key or adopt wrong key and a kind of technology that misplaces also can unblank, provide a kind of lock core that must adopt correct key just can unblank.

The technical solution used in the present invention is such: a kind of mechanical lock, comprise lock core base, lock core piece, fixed block, turning cylinder, head end joint, slide plate, compressing tablet and shell fragment, cam and gear, wherein,

Offer chute and through hole A on the described lock core base, a side of described chute offers groove and connects with through hole A, and an end of lock core base offers post hole A portion, offers passage between described post hole A portion and the chute; Lock core base extends outward pedestal near an end of post hole A portion, and pedestal is provided with at least one fixing hole through hole A and is provided with spring B; Also comprise:
