Problems solved by technology

However, these mechanical combination locks cannot identify whether the password is completely disrupted, resulting in that the password is not completely disrupted when the door is closed, and even in the open state, it cannot be found, which has potential safety hazards.

Embodiment Construction

[0015] A mechanical combination lock with garbled code detection function, comprising a lock housing 1, a combination dial 2, an arbor 3, a driving wheel 4, a lock bolt 5, an unlocking link 6, an active transmission pin 7, a passive transmission pin 8, a second A runner 9 , a second runner 10 , a third runner 11 , and a magnetic proximity switch 12 .

[0016] A permanent magnet 13 is embedded on the outer edge of the third runner 11, and a magnetic proximity switch 12 is correspondingly installed on the outside of the third runner 11, and an indicator light 14 is connected in series on the magnetic proximity switch 12;

[0017] When the notch 15 on the third rotating wheel 11 was turned to a designated position, the permanent magnet 13 turned to a position close to the magnetic proximity switch 12, the magnetic proximity switch 12 was disconnected, and the indicator light 14 was extinguished, indicating that the password was not completely disturbed; When the notch of the thir...

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

[0001] technical field [0002] The invention relates to the field of mechanical combination locks, in particular to a mechanical combination lock with the function of detecting garbled codes. Background technique [0003] At present, known mechanical combination lock is made up of lock housing, driving wheel, runner, unblanking stop lever, dead bolt, combination dial, mandrel. The core part of the combination lock is a wheel set composed of three or four wheels. Although the appearance of the wheel set designed by each manufacturer is different, their principle is the same. The notches of all the wheels in the group are aligned at the specified positions to form a gap, and the unlocking lever enters the gap under its own gravity or spring force. At this time, the combination dial is rotated in the specified direction, and the combination lock is opened; when it is turned in the opposite direction to open More than four turns (three wheels) or more than five turns (four whe...
