Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and more specifically, to a vertically installed bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. In Guangzhou, Guangdong, my country, more than 90% of the main lines leading to the distribution rooms of buildings with more than 12 floors use bus ducts; bus ducts are used from 630KVA transformers to distribution cabinets.

[0003] For example, the authorization announcement number CN213693086U discloses a vertically mounted bus duct, in which the upper cover and the lower cover are connected by a first buckle and a second buckle, wherein the n-shaped portion of the second buckle can provide a certain pre-tightening force when the bolt is locked to prevent the bolt from loosening, replacing the role of the spring gasket in the traditional connection method. During on-site installation, the upper cover can be moved vertically downward to complete the installation and fixation of the upper cover and the lower cover.

[0004] During use of the above solution, workers are required to tighten multiple bolts between the upper cover and the lower cover to fix the upper cover and the lower cover. When the bus duct is installed vertically, the connecting parts between the two bus ducts need to be aligned and inserted into the connector, and a spring bracket needs to be installed on the bus duct, and then the bus duct and the spring bracket need to be fixed on the channel steel fixing frame. Only then can the two buckles be connected and the upper cover and the lower cover can be installed. In the process of tightening with bolts, the whole process takes a long time, the steps are cumbersome and there are certain safety hazards. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a vertically installed bus duct which is quicker to install.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A vertically installed bus duct comprises an upper cover and a lower cover connected to the upper cover, a copper bar is arranged between the upper cover and the lower cover, and slots for placing the copper bar are arranged in the upper cover and the lower cover, characterized in that: a connecting portion is arranged on the side of the upper cover, and a docking portion is arranged on the lower cover corresponding to the connecting portion,

[0008] The connection part includes a plurality of connection blocks evenly distributed on the side of the upper cover, a card slot is provided on one side wall of the connection block, and a shielding sheet is provided on the inner side of the upper cover.

[0009] The docking part includes a plurality of connection grooves and fixing members corresponding to the connection blocks. The connection blocks extend into the card slots. The side walls of the connection grooves are provided with docking grooves corresponding to the card slots. The docking grooves are connected with the connection grooves. The fixing members extend from the docking grooves into the card slots to fix the upper cover and the lower cover.

[0010] A waterproof gasket is provided on the side of the lower cover corresponding to the shielding piece.

[0011] The utility model is further configured as follows: the fixing member comprises a rod body and a convex block arranged on the rod body and used for extending into the clamping slot; the convex block and the rod body are integrally formed; and protrusions for clamping are arranged on both end surfaces of the rod body.

[0012] The utility model is further configured as follows: the two side lines of the protrusion are inclined, and the cross section of the protrusion is trapezoidal.

[0013] The utility model is further configured as follows: the convex block is hollow, and a friction sheet is arranged on the outer wall of the convex block.

[0014] The utility model is further configured as follows: the upper cover, the lower cover and the fixing piece are all made of rust-proof metal material.

[0015] Compared with the shortcomings of the prior art, the beneficial effects of the utility model are:

[0016] By adding connecting parts and docking parts, the upper cover, the lower cover and the fixing parts are connected by mortise and tenon joints, and the connection is more stable. Furthermore, the cross-section of the protrusion is trapezoidal and is provided with a friction plate, so that the clamping connection between the protrusion and the connecting block is tighter, thereby making the connection between the upper cover and the lower cover more stable. When disassembling, only the fixing parts need to be pulled out. The connection is more stable and the disassembly and assembly between the upper cover and the lower cover is more convenient.
