Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and more specifically, to a quick and flexible installation structure for fire-resistant busbar connections. Background Technology

[0002] Fire-resistant busbar trunking is a key piece of equipment in power systems, primarily used for power transmission and distribution to ensure the safe operation of the power system under extreme conditions such as fires. Fire-resistant busbar trunking typically consists of conductive busbars, insulating materials, and a protective shell. It possesses excellent conductivity and fire resistance, effectively reducing energy loss and improving power transmission efficiency. Furthermore, the installation process of fire-resistant busbar trunking is relatively simple, reducing construction time and increasing work efficiency. Fire-resistant busbar trunking is widely used in various fields, including industrial sectors, commercial buildings, public facilities, and high-rise buildings. However, existing technologies have the following shortcomings in their application:

[0003] The existing busbar trunking has too few mounting bolt holes, resulting in insufficient connection and fastening points. After the cover plate is installed, it is prone to loosening and displacement under vibration or external impact, which may cause malfunctions and is not conducive to actual use.

[0004] Therefore, there is an urgent need for a quick and flexible installation structure for fire-resistant busbar connections to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing busbar trunking has too few screw holes, resulting in insufficient connection and fastening points. After the cover plate is installed, it is easy for it to loosen and shift under vibration or external impact, which may cause malfunctions and is not conducive to practical use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick and flexible installation structure for fire-resistant busbar connections is proposed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] A quick and flexible installation fire-resistant busbar connection structure includes a fire-resistant busbar trunking body. Conductive busbars are installed at both ends of the fire-resistant busbar trunking body. A first L-shaped plate and a second L-shaped plate are fixedly connected to opposite side surfaces of the fire-resistant busbar trunking body. The first L-shaped plate has two parallel first mounting screw holes near both ends, and the second L-shaped plate has two parallel second mounting screw holes near both ends. A connection mechanism is provided at both ends of the fire-resistant busbar trunking body, and one or more first mounting connection holes are provided on both side surfaces at both ends of the fire-resistant busbar trunking body.

[0010] As a preferred technical solution of this application, the connection mechanism includes two V-shaped mounting plates installed on one end face of the fire-resistant busbar trunking body. The V-shaped mounting plates have two third mounting screw holes and a second mounting connection hole located between the two third mounting screw holes.

[0011] As a preferred technical solution of this application, the first mounting screw hole and the second mounting screw hole have the same specifications.

[0012] As a preferred technical solution of this application, the two first L-shaped plates and the two second L-shaped plates are symmetrically arranged about the central axis of the fire-resistant busbar trunking body.

[0013] As a preferred technical solution of this application, the two V-shaped mounting plates on one side end face of the fire-resistant busbar trunking body are arranged opposite to each other, and the two third mounting screw holes are parallel.

[0014] As a preferred technical solution of this application, the first L-shaped plate and the second L-shaped plate are both integrally formed with the metal shell of the fire-resistant busbar trunking body.

[0015] As a preferred technical solution of this application, the conductive busbar is made of a metal conductive material.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting two first L-shaped plates and two second L-shaped plates, four first mounting screw holes are opened on each of the two first L-shaped plates, and four second mounting screw holes are opened on each of the two second L-shaped plates. This ensures that the main body of the fire-resistant busbar trunking has four first mounting screw holes and four second mounting screw holes on each side. This facilitates the subsequent installation and fixing of the two cover plates by using fastening bolts in conjunction with the first and second mounting screw holes. It can ensure the stability of the two cover plates after installation, effectively resist vibration and external impact, prevent the cover plates from shifting and falling off, and benefit practical use.

[0018] 2. The side plate can be easily installed and fixed by using the first mounting connection hole on the connecting support plate and tightening bolts and nuts. Attached Figure Description

[0029] Example:

[0030] like Figure 1-5As shown, this embodiment proposes a quick and flexible installation structure for fire-resistant busbar connections, including a fire-resistant busbar trunking body 1. Conductive busbars 2 are installed at both ends of the fire-resistant busbar trunking body 1. First L-shaped plates 3 and second L-shaped plates 4 are fixedly connected to opposite side surfaces of the fire-resistant busbar trunking body 1. The two first L-shaped plates 3 and two second L-shaped plates 4 are symmetrically arranged about the central axis of the fire-resistant busbar trunking body 1. The first L-shaped plates 3 and second L-shaped plates 4 are integrally formed with the metal shell of the fire-resistant busbar trunking body 1. A cover plate is fitted to the first L-shaped plates 3 and second L-shaped plates 4. Two parallel first mounting screw holes 5 are provided near both ends of the first L-shaped plates 3, and two parallel second mounting screw holes 6 are provided near both ends of the second L-shaped plates 4. The first mounting screw hole 5 and the second mounting screw hole 6 are of the same specification, so that the multiple first mounting connection holes on the cover plate correspond to the four first mounting screw holes 5 on the first L-shaped plate 3 and the four second mounting screw holes 6 on the second L-shaped plate 4 respectively. Both ends of the fire-resistant busbar trunking body 1 are provided with connection mechanisms. Then, by using the corresponding number of fastening bolts, one of the cover plates is installed and fixed by cooperating with the four first mounting screw holes 5 and the four second mounting screw holes 6. This can resist vibration and external impact, prevent the cover plate from shifting and falling off, and help ensure the stable operation of the fire-resistant busbar trunking body 1. The fire-resistant busbar trunking body 1 has one or more first mounting connection holes 9 on both sides of the two ends. With the fastening bolts and nuts, it is convenient to install and fix the side plates.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the connection mechanism includes two V-shaped mounting plates 7 installed on one side end face of the fire-resistant busbar trunking body 1. The V-shaped mounting plates 7 have two third mounting screw holes 8 and a second mounting connection hole 11 located between the two third mounting screw holes 8. The two V-shaped mounting plates 7 on one side end face of the fire-resistant busbar trunking body 1 are arranged opposite to each other, and the two third mounting screw holes 8 are parallel. Through the third mounting screw holes 8 opened on the V-shaped mounting plates 7, the connection and fixation of the conductive busbar 2 can be assisted, ensuring reliable electrical connection and stable current transmission.

[0032] like Figure 1 As shown, the conductive busbar 2 is made of a metal conductive material, which facilitates power transmission through the conductive busbar 2.

[0033] Specifically, when using this quick and flexible fire-resistant busbar connection structure: First, when installing two cover plates, attach one cover plate to the first L-shaped plate 3 and the second L-shaped plate 4, aligning the multiple first mounting connection holes on the cover plate with the four first mounting screw holes 5 on the first L-shaped plate 3 and the four second mounting screw holes 6 on the second L-shaped plate 4. Then, use the corresponding number of fastening bolts and nuts, engaging with the four first mounting screw holes 5 and the four second mounting screw holes 6, to secure one cover plate. Then, attach the other cover plate to another first L-shaped plate 3 and another second L-shaped plate 4, aligning the cover plate with the four first mounting screw holes 5 on the other first L-shaped plate 3. Corresponding to the four second mounting screw holes 6 on the second L-shaped plate 4, the corresponding number of fastening bolts and nuts are used again, in conjunction with the other four first mounting screw holes 5 and the other four second mounting screw holes 6, to achieve the installation and fixation of the other cover plate, so that the two cover plates are located on opposite sides of the fire-resistant busbar trunking body 1. Through the eight first mounting screw holes 5 and the eight second mounting screw holes 6, the connection points between the cover plate and the first L-shaped plate 3 and the second L-shaped plate 4 can be increased, which can better resist vibration and external impact, prevent the cover plate from shifting and falling off, help ensure the stable operation of the fire-resistant busbar trunking body 1, and improve the installation stability. The fixing effect is enhanced by the connection of multiple fastening bolts, which is beneficial to practical use.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
