Locking device for busway plugging box

Abstract

The invention provides a locking device for a busway plugging box. The locking device comprises two groups of locking mechanisms, four first positioning plates, four second positioning plates, four third positioning plates and four fourth positioning plates, wherein the two groups of locking mechanisms are respectively fixed on the side walls of a box body of the plugging box; the four first positioning plates are fixed at the outer edge of a cover plate of the plugging box; the four second positioning plates are fixed at the top of the box body of the plugging box; the four third positioningplates are fixed at the bottom of the box body of the plugging box; the four fourth positioning plates are fixed at the top of a busway; each group of locking mechanism comprises a first locking mechanism and a second locking mechanism which are symmetrically arranged. The locking device provided by the invention has the advantages of simplicity in mounting, good stability and good safety.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking device for a busway plug-in box. Background technique [0002] The busway system is a high-efficiency power distribution device for transmitting current, especially to meet the needs of increasingly taller buildings and large-scale factories for economical and reasonable wiring, so it is widely used in the connection between low-voltage power distribution panels and large and medium-sized loads , such as modern workshops, factory buildings and high-rise buildings, especially suitable for workshops with changing products and intensive equipment. [0003] The plug-in box is the most frequently used part in the busway system and the key part of branch current protection. It plays the role of distributing electric energy in the busway system. Therefore, the connection between the plug-in box and the busway is very important. The plug-in box and the busbar Whether the slot connection is ...

Problems solved by technology

In the prior art, some plug-in boxes are directly attached to the bus duct body by the fastening force of the pins, thereby connecting the plug-in box to the bus duct. In order to make the connection more reliable, iron wires are usually used to wrap the plug-in box and On the periphery of the busway body, the connection method of the plug-in box is very random, and the iron wire is easy to slip off during the working process, which makes the connection between the plug-in box and the busway body loose, thus affecting the operation performance of the busway system, and the installation process is cumbersome.
