Abstract

A mechanical coded lock with the messy code detection function comprises a lock shell, a code dial plate, a mandrel, a drive wheel, a spring bolt, an unlocking connection rod, a drive transmission pin, a driven transmission pin, a rotary wheel set and a microswitch, wherein the rotary wheel set comprises three or four rotary wheels. An arc protrusion is arranged at the outer edge of the rotary wheel nearest to the code dial plate, the microswitch is correspondingly installed on the outer side of the rotary wheel nearest to the code dial plate, a button of the microswitch makes contact with the arc protrusion of the rotary wheel nearest to the code dial plate, and the microswtich is connected with an indicator light in series. Whether the mechanical coded lock is completely disturbed or not can be detected out, and the safety state of the mechanical coded lock can be conveniently displayed at the outer side of a door.

Description

There is the mechanical code lock of mess code measuring ability

Technical field

The utility model relates to mechanical code lock field, particularly relates to the mechanical code lock with mess code measuring ability.

Background technology

At present, known mechanical code lock is made up of lock housing body, driving wheel, runner group, the pin of unblanking, dead bolt, password dial, axle.The core part of coded lock is by three or four wheels that runner forms, though the wheels outward appearance of each producer design is different, but their principles are identical, while pressing correct way to upper password by password dial, in wheels, the recess of all runners forms gap in assigned address alignment, the pin of unblanking enters this gap under self gravitation or spring-force driven dual, and at this moment, to assigned direction rotation password dial, coded lock is opened; More than enclosing to more than unlatching rightabout rotation four circles (three runners) or five (four runners), make a slice runner recess nearest with password dial leave assigned address, be that password is upset completely, at this moment coded lock is in the highest safe condition, and again opening need be again to upper whole password.But whether these mechanical code locks can not be upset by recognition code completely, cause password at closing time not upset completely even and can not be found in opening, there is potential safety hazard.

Utility model content

The purpose of this utility model is to provide the mechanical code lock with mess code measuring ability, and whether this mechanical code lock can not only be measured mechanical code lock and upset completely, and can be easily at the safe condition that shows outdoors this mechanical code lock.

The technical scheme adopting is:

Have the mechanical code lock of mess code measuring ability, comprise lock housing body, password dial, axle, driving wheel, dead bolt, the connecting rod of unblanking, active trundle, passive trundle, runner group, microswitch, wherein runner group comprises three or four runners; Its technical essential is: be provided with arc convex apart from the outer rim of the nearest a slice runner of password dial, at a microswitch of this corresponding installation in runner outside, in the time that this runner rotates, the button of microswitch can touch mutually with the arc convex of this runner, the indicator lamp of connecting on microswitch.

Its operating principle is: when going to assigned address apart from the recess of the nearest a slice runner of password dial, arc convex on this runner compresses the button of microswitch, and microswitch is communicated with or disconnects, and indicator lamp is bright or go out, and represents that password is not upset completely; In the time leaving assigned address apart from the recess of the nearest a slice runner of password dial, the arc convex on this runner discharges the button of microswitch, and switch disconnects or is communicated with, and indicator lamp goes out or be bright, represents that password is upset completely; Reach effective identification mechanical code lock and whether upset the object of state in password completely.

Compared with prior art, its advantage is whether completely to be upset to come by detecting password the safe condition of feedback cipher lock, easily corresponding signal is transferred out simultaneously, adopts runner and microswitch touching mode with arc convex, simple in structure, survey reliable.

Detailed description of the invention

There is the mechanical code lock of mess code measuring ability, comprise lock housing body 1, password dial 2, axle 3, driving wheel 4, dead bolt 5, the pin 6 of unblanking, active trundle 7, passive trundle 8, the first runner 9, the second runner 10, the 3rd runner 11, microswitch 12, microswitch adopts closed type.

The outer rim of the 3rd runner 11 is provided with arc convex 13, corresponding in the 3rd runner 11 outsides a microswitch 12 is installed, and the button 14 of microswitch 12 and the arc convex 13 of the 3rd runner 11 touch, microswitch 12 indicator lamp 15 of connecting;

When the recess 16 of the 3rd runner 11 goes to assigned address, the arc convex 13 on the 3rd runner 11 compresses the button 14 of microswitch 12, and microswitch 12 disconnects, and indicator lamp 15 extinguishes, and represents that password is not upset completely; In the time that the 3rd runner 11 recesses leave assigned address, the arc convex 13 on the 3rd runner 11 discharges the button 14 of microswitch 12, and switch recovers to be communicated with, and indicator lamp 15 lights, and represents that password is upset completely; Reach effective identification mechanical code lock and whether upset the object of state in password completely.

Claims

1. there is the mechanical code lock of mess code measuring ability, comprise lock housing body, password dial, axle, driving wheel, dead bolt, the connecting rod of unblanking, active trundle, passive trundle, runner group, microswitch, wherein runner group comprises three or four runners, it is characterized in that:

Be provided with arc convex apart from the outer rim of the nearest a slice runner of password dial, at a microswitch of this corresponding installation in runner outside, in the time that this runner rotates, the button of microswitch can touch mutually with the arc convex of this runner.

2. the mechanical code lock with mess code measuring ability according to claim 1, is characterized in that being in series with on microswitch indicator lamp.
