Description

Electronic padlock with high security and protection performance

Technical Field

The utility model relates to the technical field of safety protection equipment, in particular to an electronic padlock with high safety protection performance.

Background

Padlocks are the oldest and most widely used class of locks, and it can be said that other locks are all the most diverse and derived from the padlock family. The lock body of the padlock is provided with a metal stem which can be buckled and connected in a ring shape or a straight shape, namely a 'lock beam', so that the padlock is directly buckled with the lock body through the lock beam to form a closed lock.

The electronic lock is an intelligent lock which is developed after human beings enter the electronic era and controls the closing of a mechanical switch through a control circuit or chip (access control system) so as to complete unlocking and locking tasks. The electronic lock with the anti-theft alarm function replaces the traditional mechanical lock, overcomes the defects of low safety performance and poor protective performance of the mechanical lock, and is widely applied to various fields of safety precaution.

However, the electronic lock is rarely applied to the field of the traditional padlock, because the traditional padlock is too small and exquisite, complex electronic components and mechanical components are difficult to install into the padlock, the application scene of the traditional padlock is too complex, the tightness of the padlock is difficult to guarantee, impurities or liquid substances are easy to permeate into the lock, and the electronic components or the mechanical components are damaged or rusted, so that the padlock cannot be normally opened, and troubles are caused to users. However, places such as an electric energy meter box and the like which relate to circuit safety need an electronic padlock with high security protection performance urgently, and because the traditional padlock is difficult to supervise and is not beneficial to ensuring the circuit safety, the user operation is difficult to standardize, and safety accidents are easy to cause.
