Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct that is easy to assemble. Background Art

[0002] The bus duct is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. The bus duct is relatively cumbersome in the installation process and has poor flexibility. It needs to be installed quickly to improve work efficiency. The bus duct described in Publication No. CN219643540U is easy to assemble. Its structure includes a bottom duct, a plurality of first clamps are symmetrically welded on the front end of the bottom duct cavity, and a plurality of second clamps are symmetrically welded on the rear end of the bottom duct cavity, and a first busbar is nested on the first clamp. The busbar seat and the second busbar seat nested on the second clamping seat are designed with a structural bending structure of the bottom groove, the two sets of clamping seats and the surface cover to simplify the structure. The first busbar seat, the second busbar seat and the embedded structure of each busbar are designed to facilitate rapid embedding between the bottom groove and the surface cover. The overall installation of the busbar duct is mostly achieved by embedding. Only screws or rivets are needed for rapid fixation at the end of the overall fixation. This installation method has high installation efficiency. The utility model has a reasonable structure and fast installation. It is expected to produce high social and economic benefits and should be widely promoted and used in the market. However, the existing technology still has defects:

[0003] 1. There is no heat dissipation mechanism in the existing technology. The bus duct will generate a lot of heat during the power transmission process, so heat dissipation is required to ensure its safe and stable operation.

[0004] 2. In the prior art, the installation is completed by fixing the third mounting plate on the bottom groove and the first mounting plate, and the fourth mounting plate on the second mounting plate with screws or rivets. Multiple screw fixations or rivet fixations are inconvenient for installation and disassembly. Utility Model Content

[0022] The front and rear upper and lower ends of both sides of the shell 1 are threadedly connected with bolts 10. The bolts 10 can use hexagonal bolts. The bolts 10 are threadedly connected to the mounting bracket 2. The mounting bracket 2 can be fixed to the shell 1 through the bolts 10, which is convenient for assembly and does not require too many fixing parts such as screws and nuts. Moreover, assembly and disassembly are very convenient.
