Description

Novel coded lock

Technical field: the utility model belongs to lockset kind.It is specifically related to a kind of structure of novel coded lock.

Background technology: along with the progress of human civilization, the appearance that lock has just been arranged after personal property and the privacy has been arranged, the form of lock is a lot, the wide lock that ancient times is arranged, the digital phase-locking that various cylinder locks and electromagnetic type were arranged modern age, the lock of these forms all have key to accompany with it, do not have key just can not unblank.Meanwhile also have a kind of coded lock to occur, it does not have key but the password that must remember to be formed by movable lock collar elongated slot change in location, and it demonstrates very big superiority.

Summary of the invention: the purpose of this utility model is for overcoming special this programme---the novel coded lock that proposes of needs that aforesaid ordinary construction lock must be used the problem of making troubles with key and be applicable to bicycle and electronic lock car more, its lock bridge can separate with lock body just is more convenient for using, and also increases the safety that some concrete technical measures can improve coded lock.

By as above design, the novel coded lock that this programme proposed, it includes lock body, lock bridge, the fixed axis core, movable lock collar, fixing lock collar, the lock bridge and the lock body that it is characterized in that it are separable under unlocked conditions, its fixed axis core is cylindric and is fixed on the lock body, one radially elongated slot is arranged in its body, movable lock collar is to be enclosed within on the fixed axis core and with the fixed axis core to be in active relationship, its fixedly lock collar and movable lock collar are to be enclosed within spaced reciprocally on the fixed axis core, it is fixedly fixedlyed connected between lock collar and fixed axis core, in the fixing inboard of lock collar one elongated slot is arranged also, when fixedly connected fixedly lock collar, both elongated slots are aimed at mutually, have in the inboard of each movable lock collar one with the fixing identical rectangular channel of lock collar; Its lock bridge is a parallel and middle beam that connects an end opening for circular arc, under blocking, fixedly connected with lock body, lock bridge one end is inserted in the hole of lock body, other holds the plate in rectangular cross section to be inserted into the fixed axis core, fixedly in the groove of lock collar and movable lock collar, the thickness of this square-section part is slightly less than the fixed axis core, fixedly lock collar and movably the rectangle groove width of lock collar, on the part of the square-section of lock bridge, rectangular channel is arranged also, the quantity of groove is identical with the quantity of movable lock collar, the width of rectangular channel is slightly larger than the thickness of movable lock collar, interval between its groove is slightly less than the fixedly thickness of lock collar, and the degree of depth of groove can be allowed movable lock collar rotation.

In this programme, crouch in fixing lock collar at positioning bead, this spring positioning bead of being provided with the band spring between the end face of movable lock collar and fixing lock collar, movably having a plurality of and the corresponding nest of spring positioning bead on the lock collar.Indicate numeral 0～9 in each movable latch panel surface, 10 nests are then arranged on its end face.Its movable lock collar is of five storeys, its fixedly lock collar also be of five storeys.

Adopt this programme can embody following superiority: 1. can separate under the lock body of this programme and the lock bridge unlocking condition in use, bring convenience to the user; 2. fixedly formed by lock collar and 4 layers of movable lock collar by 4 layers for this novel cipher lock, on the movable lock collar of each layer 0～9 position is arranged, its repetition mutual opening rate of making is ten thousand/, the fixed-site of the rectangular channel on its movable lock collar, just password can not change, and brings convenience for user's memory; 3. this programme product is done heat-treatment quenching raising hardness to doing concrete protective measure on other part with this lock body and lock bridge, can not be destroyed by simple tool, further improves safety and reliability; 4. it has simple in structure, easy to operate, low, the safe characteristics of repetition mutual opening rate, is worth of widely use.
