CN2063155U - Cipher lock for bicycle - Google Patents

Abstract

The utility model relates to a cipher lock for a bicycle, which is formed by the combination of the mechanical spring lock of the bicycle and the cipher lock of a safe, and comprises a cover casing, a bottom casing, a tension spring, a lock ring, a pressure spring, a cipher wheel, a cipher wrench, a cipher fixed sheet, etc. The utility model has the advantages of novel structure, convenient operation and good safety performance.

Description

Cipher lock for bicycle

Bicycle is the walking-replacing tool that people widely use, and has several hundred million at home and abroad, so the safe storage of bicycle is the problem that people generally are concerned about, various bicycle locks arise at the historic moment for this reason.But the lock majority that present bicycle is installed and used is the mechanical lock of opening with key, this lock is that security insurance is little first, the key of usefulness is easy to by others imitated because unblank, second be that key often is not good at easily losing because of keeping, when causing lock to open or not, only smash lock, cause economic loss to the user like this, also cause unnecessary waste of raw materials to country.

The purpose of this utility model just provides a kind of new bicycle lock safe and reliable, easy to use--bicycle coded lock.

The purpose of this utility model realizes by following technology.The bicycle mechanical spring structure that widely uses is now rationally improved, the switch mechanism of code that utilizes safety cabinet to use, make the two pass through structural transformation rightly, closely combine, thereby produce a kind of bicycle coded lock of novel for bicycle, it promptly mainly is the lock housing of utilizing mechanical lock, extension spring, lock ring, and will change into the structure of key switch and use cipher wheel, the password stator, the cryptography architecture of password fixed cover and password handle switch.

The utility model is rational in infrastructure, and is sturdy and durable, easy to use, need not use key, and password can change as required at any time, high safety.

Below in conjunction with accompanying drawing the utility model structure is elaborated.

Fig. 1 covers the structure elevation of shell for the utility model removes.

Fig. 2 is a lateral view of the present utility model.

By Fig. 1,2 as can be known, the utility model is by constituting with lower member: rivet, cipher wheel 2, checks cipher spanner 3, rivet 4, extension spring fixed leg 5, extension spring 6, extension spring lock ring attachment pegs 7, lock ring 8, lid shell 9, drain pan 10, rivet 11, lock ring spanner 12, password stator 13, stage clip 14, password fixed cover 15.Extension spring fixed leg 5 and extension spring 6, lock ring 8 connects, extension spring 6 is fixedly connected by extension spring lock ring attachment pegs 7 with lock ring 8, extension spring fixed leg 5 is fixed on the drain pan 10, fixedly lock ring spanner 12 is arranged on the lock ring 8, and the lock ring breach arranged, stage clip 14, cipher wheel 2 is fixed on the checks cipher spanner 3 by the password fixed cover, and with fixed password sheet 13 fixed passwords wheel 2, cipher wheel has 3 at least, have password spanner plug breach on the cipher wheel, cryptography architecture is packed on the drain pan with rivet 11, and the shell 9 and press together with drain pan 10 usefulness flanging ways of closing the lid is used rivet 1 afterwards again, 4 rivetings are lived.

The utility model is very easy to use, the way of lock with routine is installed in after the bicycle rear place, at first select easily three numbers of note, such as number, phone number, the number number that birthday and other are convenient to remember, after choosing password according to any conversion of the wish of oneself, pull then the lock ring spanner, plug and lock ring indentation, there dieback by the checks cipher spanner so just will pin, and after locking password be dialled unrest, only have and oneself know password, other people do not know, therefore, remove me, all other men unblank, open when lock such as need, the password of own usefulness is pushed decide code position, pull the checks cipher spanner, by the pulling force of extension spring to lock ring, lock has just been opened. Code number can change arbitrarily as required, but the code number after changing will remember that can't forget, do not open otherwise lock, the birth of bicycle cipherd lock extremely people is welcome, and will open up more wide application prospect for bicycle lock.

Claims (3)

1, the bicycle coded lock of forming by lid shell, drain pan, extension spring, lock ring, lock ring spanner and construction of switch, it is characterized in that said construction of switch is with stage clip 14, cipher wheel 2 also is fixed on the checks cipher spanner 3 by the password fixed cover, password stator 13 fixed passwords wheel 2, have password spanner plug breach on it, this cryptography architecture is packed on the drain pan with rivet.

2, bicycle coded lock according to claim 1 is characterized in that said cipher wheel has 3 at least.

3, bicycle coded lock according to claim 1 is characterized in that the conversion arbitrarily of said password.
