Novel jack box locking device and assembling method thereof

Abstract

The invention discloses a novel jack box locking device and an assembling method thereof. The novel jack box locking device comprises a jack box body, a locking assembly, a locking panel assembly and an oil injection lubricating assembly, wherein one side of the jack box body is detachably connected with a jack box door plate, an opening is formed in one side of the jack box body, the locking assembly is arranged in the opening, the locking panel assembly is arranged on one side of the locking assembly, and a second nut is arranged on one side, outside the jackbox body, of a lead screw to form a perfect installation position. Therefore, the maximum upward insertion distance of the lead screw is controlled, the danger that the lead screw is in contact with a conductive busbar in a bus due to the fact that the upward insertion distance is too large , and electric shock caused by misoperation is prevented through positioning, the locking assembly can be distributed and mounted, and an upper wear-resistant block is arranged on the surface of a plastic rotating handle, so that the holding usability of a user is improved, and the jack box locking device has a good quick locking device when being used.

Description

technical field [0001] The invention relates to the technical field of plug-in box equipment, in particular to a novel plug-in box locking device and an assembly method thereof. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the site installation and construction connection. As a new type of power distribution wire, the plug-in bus duct has emerged at the historic moment. Compared with the traditional cable, it fully demonstrates its superiority in the transmission of large currents. The contact resistance and temperature rise of the joints at both ends of the slot and the connection of the ...

AI Technical Summary

Problems solved by technology

[0004] However, there are some problems in the use of the existing roller-driven cleaning switchgear and its assembly method. 1. The current locking device for the plug-in box on the market lacks a good quick locking device and Most of the existing plug-in boxes are fixed by screws, and other tools are needed. Some of them are locked by plastic gear rotation, which will lead to inflexible operation, insufficient fastening, and aging after a long time, thereby reducing the cost. Overall usability, 2. The connection between the locking device of the plug-in box and the plug-in box on the market is relatively low, so that it may fall off, etc. 3. The locking device of the plug-in box currently on the market is being used for a long time When it is used, it is prone to dryness and rust, which increases the inconvenience of use, reduces the service life, and reduces the protection measures for the whole
