Abstract

The utility model discloses a changeable non-handle cipher lock. The present cipher lock commonly can not change the cipher, has poor anti-theft performance, and is opened easily by the handle. The utility model provides a cipher lock which can change the cipher, and has the advantages of optionally changeable cipher, no shifting handle, strong anti-theft performance, simple structure and convenient operation. The cipher lock is composed of a lock body, a lock hook, a cipher mechanism and a locking mechanism. The cipher mechanism comprises a lock core, a cipher inner sheet and a cipher outer sheet, and the locking mechanism comprises a lock knob post and a positioning hook.

Description

Changable cipher lock without handle

The utility model relates to a kind of coded lock.

Existing coded lock generally can not be changed password, and theftproof performance is not opened with feel by force easily.

The purpose of this utility model is to provide a kind of coded lock of interchangeable password.

The conversion arbitrarily of the utility model unlocking cipher does not have and stirs feel, and theftproof performance is strong, and is simple in structure, easy to use.

Below in conjunction with accompanying drawing its structure is further described

Fig. 1 is structure master's cut-away view of the present utility model

Fig. 2 is a side cut-away view of the present utility model

Fig. 3 is the structural representation of sheet in password outer plate of the present utility model and the password

The utility model is by lock body 1, latch hook 2, Cipher mechanism 3, locking mechanism 4 forms, Cipher mechanism comprises lock core 5, sheet 6 and password outer plate 7 in the password, spring 8, location ball 9, retainer spring 10, have the polygon endoporus at password outer plate 7, the profile of sheet 6 is the polygon-shaped of with it correspondence and is stuck in the password outer plate 7 in the password, sheet 6 has breach in password, is provided with latch 14 in a side of lock core 5, and sheet 6 is contained on the lock core 5 in the password, password outer plate 7 surface, outer garden have concave convex groove, retainer spring 10 and location ball 9 are stuck in location in the groove, and locking mechanism 4 is by lock knob post 11, location hook 12, spring 13, front end at location hook 12 is provided with helical teeth, and the middle part is provided with groove, and spring 13 is equipped with at the rear portion, the front end of lock knob post 11 is provided with shifting block, the rear end is provided with handle, and the middle part is provided with blind hole, at lock core 5 spring 8 is housed, this spring also can be contained in the blind hole, can be inserted in when lock core 5 moves up in the blind hole, the front end shifting block of lock knob post 11 is stuck in the groove of location hook 12, and the front end of location hook 12 is stuck in the tooth of latch hook 2.

Using method of the present utility model is as follows, elder generation's rotational password outer plate 7, password outer plate 7 drives sheet 6 rotations in the password, when pushing the password that sets, can not block the latch 11 of lock core 5 when the notch alignment of sheet 6 is for straight line in a plurality of passwords again, lock core 5 is under the effect of spring 8, in blind hole, withdraw from, at this moment, rotate lock knob post 11 with hand, because the front end shifting block of lock knob post 11 is stuck in the groove of location hook 12, when lock knob post 11 rotated, location hook 12 was inwardly retracted, at this moment, latch hook 2 can be extracted out, be about to lock and open, in the time will locking, latch hook 2 is inserted, with hand lock core 5 is advanced in the lock body 1, dial random password and get final product. Be provided with a positioning tooth 15 at the password outer plate, be marked with 10 lockset position of coupler of 0-9 at lock body 1, difference according to the position of positioning tooth 15 is set code-locked, if transposing password, take out earlier lock core 5, take out again sheet 6 and password outer plate 7 in the password, the gap position of sheet in the rotational password, with sheet in the password and password outer plate, lock core installs and gets final product again.

Because lock is when cutting out, in the lock core 5 indentation lock bodies 1, the external force chip of can't directly checking the number is exerted pressure, so can't unblank with feel.

The utility model is adapted to door lock, padlock, bicycle lock, drawer-lock, chain lock.
