Abstract

A mechanical coded lock with a messy code detection function comprises a lock shell, a code dialing plate, a mandrel, a drive wheel, a spring bolt, an unlocking connection rod, a driving transmission pin, a driven transmission pin, a rotary wheel set and a magnetic approach switch. The rotary wheel set comprises three or four rotary wheels. The mechanical coded lock is characterized in that a magnetic block is embedded into the outer edge of the rotary wheel nearest to the code dialing plate, and the outside of the rotary wheel is provided with the magnetic approach switch; the magnetic block can be a permanent magnetic block, and the magnetic approach switch matched with the permanent magnetic block is used for probing the permanent magnetic block; the magnetic block can be an iron block, a cobalt block or a nickel block, and the magnetic approach switch matched with the magnetic block can probe the iron block, the cobalt block or the nickel block; the magnetic approach switch is in serial connection with an indication lamp. Whether codes of the mechanical coded lock are totally messed can be detected, and the safety state of the mechanical coded lock can be displayed outside a door conveniently.

Description

A kind of mechanical code lock that function is detected with mess code

Technical field

The present invention relates to mechanical code lock field, more particularly to a kind of mechanical code lock that function is detected with mess code.

Background technology

At present, known mechanical code lock be by lock housing body, driving wheel, runner, unlocking pin, dead bolt, password dial, Heart axle is constituted.The core part of coded lock is the wheel group being made up of three or four runners, though the wheel group outward appearance of each producer design It is different, but their principles are identical, i.e., when pressing correct way to upper password by password dial, all runners in wheel group Recess aligns to form gap in specified location, unlocking pin under self gravitation or spring-force driven dual enter this gap, at this moment to Assigned direction rotates password dial, and coded lock is opened；More than to the circle of unlatching rightabout rotation four（Three runners）Or five It is more than circle（Four runners）, a piece of runner recess nearest with password dial is left specified location, i.e. password and beaten completely Disorderly, at this moment coded lock is in highest safe condition, and being again turned on need to again to upper whole passwords.But, these mechanical code locks It is unable to whether recognition code is upset completely, causes password at closing time not upset completely and can not be sent out even in opening It is existing, there is potential safety hazard.

The content of the invention

The purpose of the present invention, is to provide a kind of mechanical code lock with mess code detection function, and the mechanical code lock is not only Can measure whether mechanical code lock is upset completely, and easily can outdoors show the safe condition of the mechanical code lock.

The technical scheme of use is：

A kind of mechanical code lock that function is detected with mess code, including lock housing body, password dial, heart axle, driving wheel, lock Tongue, unlocking connecting rod, active trundle, passive trundle, light-emitting window, magnetic approach switch, wherein light-emitting window include three or four Individual runner, technical points are：In an embedded magnetic block in the nearest a piece of runner outer rim of password dial, at this Runner outside is installed by one magnetic approach switch；Above-mentioned magnetic block can be permanent magnet blocks, and the magnetic approach for matching therewith is opened Close to detect the magnetic approach switch of permanent magnet；Above-mentioned magnetic block can be iron, cobalt or nickel block, matching magnetic approach Switch as iron, cobalt or the magnetic approach switch of nickel block can be detected；One indicator lamp of series connection on magnetic approach switch.

Its operation principle is：When specified location is gone in the recess on the nearest a piece of runner of password dial, forever , close to magnetic approach switch, switch connection or disconnection, indicator lamp is bright or goes out, and represents that password is not complete for magnet or iron, cobalt, nickel block Upset entirely；When specified location is left in the recess away from the nearest a piece of runner of password dial, permanent magnet or iron, cobalt, nickel block Away from magnetic approach switch, switch off or connect, indicator lamp goes out or bright, represent that password is upset completely；Reach effectively Whether identification mechanical code lock upsets the purpose of state completely in password.

Compared with prior art, the advantage is that by detecting whether password is upset the safety locked come feedback cipher completely State, while easily transfer out corresponding signal, it is reliable using magnetic approach switch simple structure, detection.

Specific embodiment

A kind of mechanical code lock that function is detected with mess code, including lock housing body 1, password dial 2, heart axle 3, driving wheel 4th, dead bolt 5, unlocking connecting rod 6, active trundle 7, passive trundle 8, the first runner 9, the second runner 10, the 3rd runner 11, magnetic Property proximity switch 12.

An embedded permanent magnet 13 in the outer rim of 3rd runner 11, in the outside of the 3rd runner 11, correspondence installs a magnetic approach Switch 12, is in series with indicator lamp 14 on magnetic approach switch 12；

When the recess 15 on the 3rd runner 11 goes to specified location, permanent magnet 13 goes to close with magnetic approach switch 12 Position, magnetic approach switch 12 disconnects, and indicator lamp 14 extinguishes, and represents that password is not upset completely；When the recess of the 3rd runner 11 During away from specified location, away from magnetic approach switch 12, magnetic approach switch 12 resets and connects permanent magnet 13, and indicator lamp 14 is bright Rise, represent that password is upset completely；Reach the mesh whether effectively identification mechanical code lock upsets state completely in password 's.

Claims

1. a kind of mechanical code lock that function is detected with mess code, including lock housing body, password dial, heart axle, driving wheel, lock Tongue, unlocking connecting rod, active trundle, passive trundle, light-emitting window, magnetic approach switch, wherein light-emitting window include three or four Individual runner, it is characterised in that：In an embedded magnetic block in the nearest a piece of runner outer rim of password dial, in the runner Outside is installed by one magnetic approach switch；The magnetic block is permanent magnet blocks, and magnetic approach switch is the magnetic for detecting permanent magnet Property proximity switch.
