Abstract

A mechanical password lock and each password wheel thereof accordingly arranges a code control mechanism which provides limit marble hole on the lock body and marble hole on the lock rod. A block pin, a limit spring, a limit marble are arranged in the limit marble hole in order. The limit marble is closely attached to the inside of the password wheel which has concave hole. The lock body also has location marble hole inside of which a location spring and a location marble are arranged. On the password wheel, many notches are provided to match with the location marble. The code of this password lock is difficult to discover through turning the password wheel and you can change you password, which improves the safety performance.

Description

Mechanical code lock

Technical field

The utility model belongs to a kind of mechanical code lock.

Background technology

The existing machinery coded lock mostly is provided with cipher wheel and locking bar, and cipher wheel can limit the axially movable stroke of locking bar, and locking bar move axially the folding that can realize whole lockset.But this mechanical cipher is latched in following shortcoming: the people who is familiar with password structure can be by the method perception cipher wheel of rotational password wheel and the mated condition between the locking bar motion, thereby infers, judges password exactly, thereby security performance is lower.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of security performance higher mechanical code lock, and its password is difficult to utilize the method for rotational password wheel to infer, judge.

Its purpose can realize by following scheme: this mechanical code lock comprises lock body, locking bar and several cipher wheel, cipher wheel is installed in the lock body and can rotates, the cipher wheel outside is provided with a plurality of password signs, its main feature is, each cipher wheel correspondence is provided with one cipher control mechanism, each cipher control mechanism has the spacing hoodle hole that is located on the lock body, be located at the hoodle hole on the locking bar, align when coded lock is closed in opposite directions in lock body spacing hoodle hole and locking bar hoodle hole, in locking bar hoodle hole, be provided with spring and hoodle, in the spacing hoodle of lock body hole, be provided with bayonet lock successively, limit spring, spacing hoodle, the spacing hoodle of lock body is close to the inner face of cipher wheel, the inner face of cipher wheel is provided with shrinkage pool, and both are equal to the distance of cipher wheel central axis for spacing hoodle of lock body and cipher wheel shrinkage pool; Also be provided with hoodle hole, location on the lock body, be provided with retainer spring and location hoodle in the hoodle hole, location, cipher wheel is provided with recess a plurality of and location hoodle coupling, and the position of each recess is corresponding one by one with the password sign of cipher wheel outside.

Realization above-mentioned purpose scheme preferably is: the shrinkage pool periphery of cipher wheel inner face is provided with the recessed degree of depth overbank zone little than shrinkage pool.

Realize that the better scheme of above-mentioned purpose is: each cipher wheel comprises combination disk and the runner that split is provided with, combination disk is provided with connecting hole, the quantity of connecting hole is identical with the cipher wheel recess, the position of each connecting hole is corresponding one by one with the cipher wheel recess, be provided with the transmission locating piece between combination disk and the runner, the transmission locating piece is embedded in one of them connecting hole of combination disk.

Runner also can be provided with connecting hole, and described transmission locating piece can be pin, and an end of pin is embedded in the connecting hole of runner, and the other end of pin is embedded in one of them connecting hole of described combination disk.

Described transmission locating piece can be ball.

The utlity model has following advantage and effect:

When 1, the shrinkage pool that is in closure state and cipher wheel when whole lockset turns to the angle that staggers with the spacing hoodle of lock body, the spacing hoodle of lock body, limit spring are pressed into a part of length of bayonet lock in the hoodle hole of locking bar, thereby moving axially of restriction locking bar, thereby do not know that the people of password can not open lock; The people who only knows password turns to correct position when making the shrinkage pool of cipher wheel aim at the spacing hoodle of lock body with cipher wheel, just can make the spacing hoodle of lock body fall into the shrinkage pool of cipher wheel, bayonet lock withdraws from locking bar hoodle hole under the spring of locking bar and hoodle effect, locking bar is moved axially, thereby lockset is opened.

2, lock body location hoodle can constantly climb out of or fall into each recess in the cipher wheel rotation process, the action that climbs out of at every turn or fall into recess can produce vibrations and sound, and make the operator produce the dynamics sense, these dynamics senses, vibrations and sound can perturbation operation person to the judgement of spacing hoodle of lock body and cipher wheel shrinkage pool mated condition, and it is slighter that the overbank zone of cipher wheel shrinkage pool periphery can make the spacing hoodle of lock body fall into or climb out of the action of shrinkage pool, and the operator more is difficult to the armrest sense and judges password like this.

3, can change password.Only need the combination disk and the runner of cipher wheel are taken apart, and the transmission locating piece is inserted in another connecting hole of combination disk, just password can be changed.

4, each original password that is locked in when dispatching from the factory can be different, only need be equipped with the original cards of explanation original password when dispatching from the factory, even the user has forgotten password in the future, only need combination disk be reorientated by the explanation of original cards and can return to factory state.
