Bus duct jack box locking device

Abstract

The invention provides a bus duct jack box locking device which comprises a left locking hook and a right locking hook installed outside a box body, the left and right locking hooks are parallelly and vertically arranged outside the box body, and one ends of the left and right locking hooks extend to lower side of the box body; the left and right locking hooks are movably connected with the box body; restoring springs are arranged outside the box body, and the restoring springs are respectively located on outer surfaces of the left and right locking hooks; and two ends of the restoring springs are respectively fixedly connected with the box body and corresponding left and right locking hooks, by the elasticity of the restoring springs, the shrinkage of the left and right locking hooks is realized, and the left and right locking hooks hook a bus duct shell, thus a jack box of the bus duct is locked. By locking the bus duct with the locking device, the connection between the jack box and the bus duct is more firm, and the coordination is better, thus the use safety of the bus duct is greatly improved and the operation of the bus duct is ensured.

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] Low-voltage busway is an important product responsible for power transmission in the field of low-voltage power transmission and distribution. It has incomparable advantages for cables in high-current and industrial and mining sites. The most important and weakest link is the "plug-in unit". The key of the plug-in unit is the socket between the plug-in box and the busway body. In many places, because the pins of the plug-in box and the busbar of the busway socket are not tightly inserted, the fixing of the plug-in box and the busway is not firm, and the vibration during the operation of the busway causes poor contact between the pins and the busway, resulting in the burning of the entire busway , and even burn out a large number of electrical equipment, causing serious economic losses and potential safety hazards.

AI Technical Summary

Problems solved by technology

In many places, because the pins of the plug-in box and the busbar of the busway socket are not tightly inserted, the fixing of the plug-in box and the busway is not firm, and the vibration during the operation of the busway causes poor contact between the pins and the busway, resulting in the burning of the entire busway , and even burn out a large number of electrical equipment, causing serious economic losses and potential safety hazards

[0003] The locking device of the conventional plug-in box adopts ordinary bolts and nuts to be tightened up and down one by one. This method cannot determine whether the pins of the plug-in box and the busbar of the bus duct are inserted tightly, and whether the plug-in box and the bus duct are firmly fixed. It is difficult to guarantee the product running quality

[0004] When installing the product, due to the harsh installation environment and the skill level of the installation workers, it is easy to cause the bolts and nuts to not be tightened when installing a large number of plug-in boxes. The plug-in box and the bus duct are not firmly fixed. The busbar is loose, and the fixing bolts of the plug-in box are tightened one by one, which is not conducive to batch installation and affects the efficiency of installation
