Lighting bus duct mounting structure

Abstract

This utility model relates to an installation structure for a lighting busbar trunking, including a busbar trunking housing and a hoisting assembly. The bottom of the busbar trunking housing is provided with a mounting plate, and one side of the mounting plate has a protruding strip. The hoisting assembly includes a first support plate, a second support plate, and a clamping plate. The first and second support plates are respectively positioned opposite each other on the left and right sides of the busbar trunking housing. Both the first and second support plates have a support plate portion at their lower ends, with one end of the support plate portion fitting against the top of the protruding strip. The upper ends of the first and second support plates form a connecting portion, with one end of the first support plate connecting portion overlapping with one end of the second support plate connecting portion. The overlapping portions of the two connecting portions each have corresponding screw holes. The clamping plate is located at the bottom of the second support plate connecting portion, and has clamping grooves on both sides that engage with the middle of the two connecting portions. Bolts pass through the clamping plate, ensuring a tight fit between the clamping plate and the connecting portion. By embedding the support plate portion into the positioning groove and fitting against the bottom of the protruding strip, a limiting function is achieved, preventing the support plate portion from easily deforming.

Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to an installation structure for a lighting busbar. Background Technology

[0002] Traditional lighting busbar sling installation structure, such as Figure 1 As shown, a U-shaped lifting plate is fitted onto the outside of the busbar trunking, and the bent portions at both ends of the lifting plate support the bottom sides of the busbar trunking for fixation. While this installation method is simple and efficient, under long-term static loads, the bent portions at the bottom of the lifting plate are prone to plastic deformation, which could lead to the busbar trunking falling off. Furthermore, because the lifting plate is an integral structure, it must be fitted onto the busbar trunking from one end, making it impossible to add the lifting component after the busbar trunking is fixed, resulting in relatively cumbersome installation. Chinese patent document CN202322764215.8 discloses a lighting busbar trunking. In this application, the busbar trunking bracket, along with two threaded posts, effectively supports the busbar trunking. While this lifting method can prevent deformation of the sheet metal, it limits the functionality of the bottom of the busbar trunking, making it inconvenient to insert various electrical appliances. Therefore, those skilled in the art need to improve upon the existing methods to address these shortcomings. Utility Model Content

[0003] This utility model addresses the aforementioned problems by disclosing a lighting busbar installation structure, which solves the problem of deformation that easily occurs in traditional busbar hoisting structures due to long-term use; by adopting a prefabricated hoisting component structure, it meets the needs of adding hoisting components, thus facilitating installation and disassembly.

[0004] The specific technical solution is as follows:

[0005] A lighting busbar installation structure includes a busbar housing and a hoisting assembly. The busbar housing has two symmetrically aligned mounting plates integrally formed on both sides of its bottom opening. A horizontally protruding strip is provided on the side of the two mounting plates furthest from each other. The hoisting assembly includes a first support plate, a second support plate, a clamping plate, and a hoisting rod. The first and second support plates are respectively positioned opposite each other on the left and right sides of the busbar housing. The lower ends of both the first and second support plates are bent and have support plate portions for supporting the bottom sides of the busbar housing. One end of each support plate portion extends to the mounting plate and is fitted against the top of the protruding strip. The upper ends of the first and second support plates are Z-shaped bent and respectively form a... The connecting part, wherein the connecting part of the first support plate is higher than the connecting part of the second support plate, such that one end of the connecting part of the first support plate is attached to the top of one end of the connecting part of the second support plate and overlaps with it; the overlapping part of the two connecting parts is provided with corresponding screw holes; the clamping plate is located at the bottom of the connecting part of the second support plate, and the clamping plate is provided with clamping grooves on its left and right sides and respectively engages with the middle of the two connecting parts; the clamping plate is provided with through holes corresponding to the screw holes, and bolts are passed through the through holes and screw holes from bottom to top; a threaded connector is screwed to the upper end of the bolt, so that the clamping plate and the connecting part are tightly fitted; the upper end of the threaded connector is screwed to the hoisting rod, thereby connecting and fixing it to the wall.

[0006] Furthermore, the width of the card slot is adapted to the width of the two connecting parts, and the inner walls of the card slots on both sides of the card plate are respectively fitted to the middle of the first connecting part and the second connecting part.

[0007] Furthermore, the bottom end of the threaded connector is provided with a gasket, so that the threaded connector is pressed against the connecting part by the gasket.

[0008] Furthermore, the first support plate and the second support plate are respectively attached to both sides of the busbar trunking housing.

[0009] Furthermore, both the lower ends of the first and second support plates are provided with V-shaped reinforcing sections.

[0010] Furthermore, a positioning groove for positioning the support plate is formed between the convex strip and the bottom of the busbar housing, and the height of the positioning groove is adapted to the thickness of the support plate.

[0011] Furthermore, the convex strip is integrally formed with the busbar housing.

[0012] The beneficial effects of this utility model are reflected in:

[0013] (1) Compared with the traditional busbar trough hoisting structure, this application adopts an integrally formed protrusion on the side wall of the busbar trough mounting plate. By embedding the support plate into the positioning groove and fitting it with the bottom of the protrusion, it plays a limiting role. At the same time, in conjunction with the reinforcement at the bottom of the support plate, it can effectively avoid the problem of deformation of the support plate due to long-term use.

[0014] (2) This utility model adopts a prefabricated hoisting component structure. The first support plate and the second support plate are connected on the left and right sides, and then the clamping plate is installed and fasteners are used to fix them, which meets the needs of adding hoisting components and facilitates installation and disassembly.

[0015] (3) In this utility model, a clamping plate is used to clamp and limit the two support plates on the left and right sides, which can prevent the two support plates from rotating horizontally when the busbar is subjected to a straight force, thereby avoiding the problem of the support plates deviating from or detaching from the busbar and ensuring the reliability of the hoisting structure.
