Abstract

A self-setting cipher lock, comprises lock body and lock pin. In the lock pin, a setting dynamic wheel and a wany edge disk are rigidly connected by a shaft, in the setting dynamic wheel, a wind spring is arranged, which is fixed to the shaft and setting dynamic wheel inner-casing by its inner end and outer end; the setting dynamic wheel is a pair of gear and rack, a rob shaped bolt is placed in the bolt socket which is arranged in the lock casing under the setting dynamic wheel, and an equidistant transversal groove is made on the wany edge disk fitting surface for movable fit with the bolt. on each side tooth of the setting dynamic wheel, a pressing-bolt is arranged which can lock the bolt. The invention has advantages as simple structure, low cost, freely-set cipher, and convenient use.

Description

From establishing coded lock

Technical field

The present invention relates to a kind of coded lock is the safety lock that user oneself is provided with password.

Background technology

It is prefabricated that the password of Current Password lock is producer, the user uses, and is therefore very dangerous, and user oneself can not arbitrarily change password, in case password is forgotten, lock then can not be opened, and has only and changes lock after its destruction dismantled, otherwise not have way, moreover also snatched password by the robber easily in using or take that barbarous means saws, cut, cut etc. will be locked destruction still can larceny, as automobile, safety cabinet is stolen happens occasionally, therefore, its theftproof is relatively poor.

Summary of the invention

Its purpose of the present invention is: provide a kind of and establish coded lock certainly, it is simple in structure, and it is lock cipher that the user can adopt oneself to like the data of seeing, thereby has improved the confidentiality and the security reliability of lock, the generation of also stopping thievery.

The present invention is achieved in that a kind of from establishing coded lock, comprises, lock body, lock core are provided with driving wheel and scarce limit disk by the affixed one of axle in its lock core, and described putting is provided with coil spring in the driving wheel, its inside and outside two ends respectively with axle with to put the driving wheel inner casing affixed; Putting driving wheel is toothed disc and tooth bar engagement, and dead bolt places in the interior dead bolt cave of driving wheel below lock housing, and its dead bolt is bar shaped, and itself and scarce limit disk fitting face are provided with equidistant horizontal groove with it movingly; The described runner disc both sides tooth of putting is respectively equipped with door and presses tongue, presses tongue that dead bolt is locked.Its door and pressure tongue are the triangle cone, and its bottom connects with its housing by return spring.It is corresponding that the slot pitch of glossal canal equals to put driving wheel one circle length on the described dead bolt.

The present invention is simple in structure, and is with low cost, but it is random strong, and password can be set arbitrarily, can being kept absolutely secret property, thus reach safe and secret i.e. purpose easily in using.

Elaborate its structure with accompanying drawing in conjunction with the embodiments.

The specific embodiment

Its structure of the present invention is as shown in Figure 1: a kind of from establishing coded lock, comprise that lock body, lock core are provided with driving wheel 1 and pass through axle 5 affixed one with scarce limit disk 2 in its lock core, described putting is provided with coil spring 7 in the driving wheel 1, its inside and outside two ends are respectively with axle 5 with to put the driving wheel inner casing affixed; Put driving wheel 1 and be toothed disc and tooth bar engagement, dead bolt places in the interior dead bolt cave of driving wheel below lock housing, and its dead bolt 4 is bar shaped, and itself and scarce limit disk 2 fitting faces are provided with equidistant horizontal groove 401 with it movingly; The described runner disc both sides tooth of putting is respectively equipped with door 6 and presses tongue 3, presses tongue with dead bolt 4 lockings.

Its door 6 and pressure tongue 3 are the triangle cone, and its bottom connects with its housing by return spring 601,301.

It is corresponding that the slot pitch of glossal canal 401 equals to put driving wheel one circle length on the described dead bolt 4.

Described dead bolt 4, put driving wheel 1, lack limit disk 2, adopt metal material, described coil spring 7 adopts the spring guiding principles, and described return spring 601,301 adopts the stage clip mode of occupation:

At first establish password:

With door 6 with press tongue 3 to push back in the cave, put driving wheel 1 and make and lack limit disk 2 and do not join with dead bolt 4, will forward to and lack limit 201 and be positioned at the i.e. coded lock open position herein in institute dead bolt groove 401 places that require, password setting finishes like this.

Mode of occupation:

Lock then to unclamp and put driving wheel 1 by the collision dead bolt, its return under coil spring 7 effects makes to be put driving wheel 1 and rotates, and lacks limit 201 and leaves groove 401 thereby make, and makes the lock locking and at door 6 with press dead bolt is firmly secured in its lock body in the lock tongue slot more.

Open the lock process:

As long as put several seated position that driving wheel turns to password setting, at this moment, can open lock, easy to use, safe and reliable.

Claims

1. establish coded lock certainly for one kind, comprise that lock body, lock core is characterized in that: driving wheel (1) is set in its lock core passes through axle (5) affixed one with scarce limit disk (2), described putting is provided with coil spring (7) in the driving wheel (1), its inside and outside two ends are respectively with axle (5) with to put the driving wheel inner casing affixed; Put driving wheel (1) and be toothed disc and tooth bar engagement, dead bolt places in the interior dead bolt cave of driving wheel below lock housing, and its dead bolt (4) is bar shaped, and itself and scarce limit disk (2) fitting face are provided with equidistant horizontal groove (401) with it movingly; The described runner disc both sides tooth of putting is respectively equipped with door (6) and presses tongue (3), presses tongue that dead bolt (4) is locked.
