Anti-mistake electronic padlock

Abstract

The invention discloses an anti-error electronic padlock which comprises a lock body, a lock hook, an electronic blocking mechanism and an internal circuit, wherein the lock hook is moveably arranged on the lock body; the lock hook can move back and forth between an unlocking position and a locking position; a first limiting slot is formed on the lock hook; the electronic blocking mechanism is arranged in the lock body; the internal circuit is arranged in the lock body and is connected with the electronic blocking mechanism; the electronic blocking mechanism comprises a spring bolt mechanism and an electronic driving element; the spring bolt mechanism comprises a spring bolt capable of moving back and forth between a blocking position and a non-blocking position; the spring bolt is matched with the first limiting slot; the electronic driving element is connected with a driving signal output end of the internal circuit; the electronic driving element is provided with a stretchable limiting pin; when the limiting pin of the electronic driving element stretches out, the limiting pin limits the motion of the spring bolt; when the internal circuit controls the limiting pin of the electronic driving element to retract, the limiting to the spring bolt is released by the limiting pin. The anti-error electronic padlock provided by the invention has the advantages of simple structure and high reliability.

Description

technical field [0001] The invention relates to a lock, in particular to a misuse-preventing electronic padlock. Background technique [0002] In order to prevent human operation accidents, microcomputer anti-misoperation locking systems are commonly used in substations and power plants to lock operating equipment. The purpose of the locking devices used is to prevent human misoperation. However, traditional mechanical locks and unlocking devices usually adopt a contact connection structure, which has disadvantages such as low safety, high failure rate, and large functional limitations. [0003] With the development of power equipment, the traditional single locking method can no longer meet the needs, and there are more and more applications that require comprehensive locking methods, and locking devices with both mechanical and electrical locking functions are required. At the same time, traditional locking devices are gradually no longer suitable for new anti-misoperatio...

AI Technical Summary

Problems solved by technology

However, traditional mechanical locks and unlocking devices usually adopt a contact connection structure, which has disadvantages such as low safety, high failure rate, and large functional limitations.

[0003] With the development of power equipment, the traditional single locking method can no longer meet the needs, and there are more and more applications that require comprehensive locking methods, and locking devices with both mechanical and electrical locking functions are required

At the same time, traditional locking devices are gradually no longer suitable for new anti-mislocking occasions due to backward technology and limited precision.

[0004] Although the existing electronic padlocks meet the functions of electromechanical locking, the existing electronic padlocks all have the problems of complex structure and low reliability.
