The utility model solves the technical scheme that its technical problem adopts: lock core appearance design is become T-shaped, and marble hole is around keyhole longitudinal arrangement.The key perforation that the front end of lock core marble hole is less with diameter communicates, and rear end and the lock marble hole corresponded communicate.A pellet is all respectively had in lock core marble hole and lock marble hole.Under the action of the spring, lock spring puts in lock core and makes it to block and can not rotate, and lock is just lockable.When unblanking, with one, the key of band key bit is injected keyhole, now, the key bit be looped around on the key also injects in key perforation corresponding separately all simultaneously, is back into together in lock body by the lock spring putting in lock core, then rotates key and just can unblank.Because the lock spring length putting in lock core is different, be responsible for they being back into the key bit length of going in lock body also different.It is 5mm that such as certain lock spring puts in the length of lock core, the length of that root key bit corresponded i.e. 5mm.According to this feature, the utility model can compile and edit password according to this key key bit length.Such as the length of first key bit in the key left side of certain lock is 6mm, successively the length of each rooted tooth be 2,5,4,1,3,6mm, so password of this lock is exactly 6254136.But this password is not used for directly unblanking, but anti-standby user is once lose key, can go separately to buy a key billet, and according to the key bit of this password by same length original on base, being cut into required length respectively can unblank.

In order to improve anti-performance of unblanking further, lock spring of the present utility model there is one diameter be greater than the shaft shoulder of lock core marble hole, to guarantee that it can not be taken out from lock by people.Meanwhile, because the spring after pellet is pressed on this road shaft shoulder, when pellet be subject to external force thrust time, spring can be protected from excessive compression.

After rotating in lock to allow key, must forward original position of inserting again to could extract from lock, and the utility model is provided with the pellet in 90 ° with keyhole and the spring of one group of transverse direction in addition, avoids its accidental in rotation to block key.

The utility model, under the state of unblanking, can take lock core and lock body apart, after the length changing some pellets, just can change password, and user can select the numeral of oneself memory applicable to compile and edit password.

The beneficial effects of the utility model are, overcome existing cylinder lock and to prevent unblanking the shortcoming of performance deficiency, also solve existing cylinder lock after key loss simultaneously, and user has to a difficult problem of asking locksmith to unblank.

Accompanying drawing illustrates that the utility model is described in further detail below in conjunction with drawings and Examples.
