Description

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

Technical field

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

Background technology

Mechanical lock, generally refers to that lock body does not have electro-motor, is different from the electronic lock that has motor in lock, and as the lock of swiping the card in hotel, mechanical lock all need to 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, a side in lockhole is provided with a row or multi-row pellet and other blade type shell fragment, after pellet, there is lock, after lock, there is spring on top, under locking state, lock is stuck under the elastic force effect of spring and is stuck between lock core base and lockhole axle.When a key inserts after lockhole, recessed protrusions press pellet on the key, pellet promotes lock, lock pressuring spring is also retracted in lock core base completely, now lockhole axle can be with key turns, lockhole axle rotates to drive and is arranged on the cam on axle, and cam rotates dead bolt is pulled open, thereby complete normally, unblanks.

Existing mechanical lock, due to its fault of construction, especially lockhole axle can rotate, and its safety is poor, usually can use prior art dislocation unlocking method to unblank, and does not need key to unblank.This method for unlocking of key that do not need is: skilled unlocking, utilize exactly small pin for the case to scratch out up or down or left or right compressing pellet or blade profile shell fragment at the iron by each shape of self-control, because of the reason of while small pin for the case by some power, when all pellets or blade type shell fragment are hooked while being urged to misalignment position with regard to this and utilize now all a kind of dislocation unlocking methods that utilize the defect of the power transmission shaft that key carrys out drive lock in-core to so-called branch art a kind of by iron) etc. or with other distinct methods, be a kind of unified address being to reach the object that misplaces opened lock.Conventionally use by " small pin for the case " and " hook ", first use " small pin for the case " to insert in lockhole, then use " hook " that pellet is pushed up in lock, and rotate small pin for the case simultaneously, because lockhole axle is cylindric, and lock is not retracted in lock core base completely, therefore the rotation meeting of lockhole axle pins lock, now, then use " hook " by each pellet to heading in lock, thereby reach the object of finally unblanking.In addition, present picking lock is generally taked forced rotating lock core, and lock is fractureed, and then rotational lock core is unblanked.
