Microcircuit switch safety lock

Abstract

The invention discloses a microcircuit switch safety lock, and belongs to the technical field of electricity utilization safety. The microcircuit switch safety lock comprises an operating rod, a coded lock, a shell, a spring and a V-shaped support; the spring and the V-shaped support are arranged in the shell, the tip end of the V-shaped support is connected with the operating rod, two branch ends of the V-shaped support extend out of the shell, locking supporting feet are arranged at the branch ends, and the locking supporting feet can be inserted into holes in a microcircuit switch and lock the micro circuit switch; part of the operating rod extends into the shell, and the other part of the operating rod penetrates through the coded lock and can be locked by the coded lock; the spring is sleeved on the operating rod, one end of the spring is fixedly connected with the operating rod, and the other end of the spring is fixedly connected with the shell; and an information label is arranged on the coded lock. According to the microcircuit switch safety lock, the microcircuit switch can be reliably locked, misoperation is prevented, and the problems of matching and management of a large number of locks and keys are solved.

Description

technical field [0001] The invention belongs to the technical field of electricity safety, and in particular relates to a microcircuit switch safety lockset. Background technique [0002] When the power distribution cabinet is overhauled and debugged, it is necessary to prevent the circuit switch from being misoperated to cause damage or safety accidents to personnel or equipment. At present, according to the safety production regulations, the safety measures to prevent misoperation mainly include: hanging the "no closing, someone is working" signboard at the switchgear that is prohibited from operation or sealing the air switch that is prohibited from operation with red insulating tape (cover). Despite the requirements of safety regulations, in reality, there are always operators who violate the regulations or close the switches that should not be closed for other reasons, resulting in accidents or losses. Locking the switch is an effective way to prevent and limit misuse....

AI Technical Summary

Problems solved by technology

Although the above two types of safety locks can realize "locking" on the air switch, there are some disadvantages: 1) The lock does not really realize the locking function after installation (the lock can still be removed), and an additional padlock is required to prevent others from operate

2) A type of lock that uses a fixed air switch shaft is easy to fall off and cannot lock the switch reliably; 3) If there are multiple air switches that need to be locked on site, each air switch corresponds to a padlock. The key management of padlocks is also inconvenient; 4) When there are many locks used on site, it becomes a new problem to identify locks, keys, and people who have the right to unlock
