Directly-inserted padlock for power facilities

Abstract

The invention provides a directly-inserted padlock for power facilities. The directly-inserted padlock for the power facilities integrates functions of preventing rusting, atmospheric pollutants and PM2.5 particles, is flexible in unlocking and locking and durable, and is very suitable to be used in modern power facilities. The directly-inserted padlock for the power facilities is characterized inthat lug bosses are arranged at positions, buckled with a lock beam, of a lock body; a protective sleeve is arranged outside the lock beam; concave tables matched with the lug bosses are arranged atthe two ends of the protective sleeve; a sealing ring is arranged on the upper end surface of a lock core assembly; the lock core assembly is fixed by a tightening screw, or a bidirectional lock catchis arranged on the lock core assembly; elastic devices comprising compression springs, or rebounding devices comprising ejector rods and the compression springs are arranged below two end surfaces ofthe lock beam in the lock body, or the elastic device is arranged below one end surface of the lock beam in the lock body; gaps in components in the lock body are filled grease, and the components inthe lock body are protected by the grease.

Description

technical field [0001] The invention relates to a padlock for electric power. Background technique [0002] Padlock is the oldest and largest family in the world of locks. It can be said that other locks are all derived from padlocks. The lock body of the padlock is equipped with a ring-shaped or straight-shaped metal stalk that can be buckled, that is, a "lock beam", so that the padlock is directly buckled with the lock body through the lock beam to form a closed lockset. [0003] During the construction of power facilities, the door keys of the power facilities are handed over to the construction personnel. For safety, the power department needs to replace the locks when taking over or in the future. Therefore, padlocks are the first choice for power facilities because they are the easiest to replace and the most convenient to use. locks. [0004] Power facilities are generally divided into indoor and outdoor, but whether it is an indoor power facility placed in a buildi...

AI Technical Summary

Problems solved by technology

[0005] The current stainless steel and copper electric padlocks have strong oxidation resistance and waterproof function, and are suitable for outdoor use. However, in addition to difficult processing and high cost, due to various harmful substances such as sulfur dioxide and hydrogen sulfide in air pollutants, And the PM2.5 particles transformed from sulfur and nitrogen oxides have been invaded for a long time. If the accumulation inside the lock body is too much, the internal parts of the lock body will be stuck, making it difficult to open, the elastic mechanism of the lock beam will fail, and the inside of the lock body will be blocked. The mechanism is stuck and cannot be unlocked

In addition, stainless steel and copper materials will also rust under harsh environmental conditions for a long time.

[0006] The problem of difficulty in unlocking power facilities has become increasingly prominent, especially for power facilities that have been installed for a long time. In an emergency, the door is often opened by destroying the lock. When the lock is scrapped, the door will also be damaged.
