Abstract
The invention discloses a mechanical lock cylinder, and belongs to the field of mechanical locksets. The mechanical lock cylinder comprises a square lock hole block A, a lock cylinder block B, an elastic sheet, a pressing sheet, a slip sheet, a spring bolt clutch sheet and the like. The invention further discloses a lock including the mechanical lock cylinder. According to the lock including the mechanical lock cylinder, the structure that the pressing sheet, the elastic sheet and the slip sheet are matched with one another are adopted, the whole solid lock cylinder is of a built-in closed design, therefore, a key is guaranteed to be unable to turn the lock cylinder, and the lock can be unlocked only when a correct key is used. After the correct key is inserted into a lock hole, the lock is unlocked without the rotation of the key, the phenomena of traditional dislocation unlocking and lock-picking are avoided, and the safety of locks, especially U-shaped locks, is improved greatly.
Description
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 row's pellet shot from a slingshot, and there is lock the pellet shot from a slingshot back, and 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, protrusions press 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, and this moment, the lockhole axle can be with key turns, and the lockhole axle rotates and drives the cam that is arranged on the axle, 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 also can unblank, provide a kind of lock core that must adopt correct key just can unblank.
