Description

Technical Field

[0001] This utility model belongs to the technical field of bent busbar trunking, and specifically relates to a bent busbar trunking structure. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute a large amount of power to various components of a distributed system and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] In actual use, existing bent busbar trunking usually requires workers to measure the construction site in advance and customize the busbar trunking to meet the construction requirements based on the measurement results, so that the bent busbar trunking fits the corner of the building. This results in low work efficiency and makes it difficult to guarantee the ideal construction effect.

[0004] Therefore, a bend-type busbar trunking structure is proposed. Summary of the Invention

[0005] This utility model provides a bent busbar trunking structure, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a bent busbar trunking structure, including a busbar trunking body one and a busbar trunking body two; wherein, the busbar trunking body one includes: a straight outer shell one and an arc-shaped outer shell one disposed on one side of the straight outer shell one; a cover shell one fixed to the top of the arc-shaped outer shell one; a straight conductive sheet one disposed inside the straight outer shell one; an arc-shaped conductive sheet one disposed inside the arc-shaped outer shell one, the arc-shaped conductive sheet one and the straight conductive sheet one being electrically connected; wherein, the busbar trunking body two includes: a straight outer shell two and an arc-shaped outer shell two disposed on one side of the straight outer shell two; a cover shell two fixed to the bottom of the arc-shaped outer shell two; a straight conductive sheet two disposed inside the straight outer shell two; an arc-shaped conductive sheet two disposed inside the arc-shaped outer shell two, the arc-shaped conductive sheet two and the straight conductive sheet two being electrically connected; a bearing shaft disposed at the center of the bottom of the arc-shaped outer shell one, the bearing shaft and the arc-shaped outer shell two being rotatably connected; and an insulating pressure roller rotatably located at the bottom of the arc-shaped outer shell one near the outer side of the arc-shaped conductive sheet one.

[0007] Furthermore, a sealing platform is provided at the bottom of the inner side of the straight outer shell 1, and a mating piece 1 is embedded in one side of the outer wall of the sealing platform 1. The mating piece 1 and the straight conductive piece 1 are electrically connected. A sealing platform 2 is provided at the bottom of the inner side of the straight outer shell 2, and a mating piece 2 is embedded in one side of the outer wall of the sealing platform 2. The mating piece 2 and the conductive piece 2 are electrically connected.

[0008] Furthermore, a fastening plate is provided on one side of the outer wall of the arc-shaped outer shell II, and a fastening hole is provided on the outer side of the straight outer shell I. A screw is screwed into the inside of the fastening hole, and a through hole is provided on one side of the outer wall of the fastening plate for the screw to pass through.

[0009] By adopting the above technical solution, and using the fastening plate and the first arc-shaped outer shell to lock and fix them, it can be ensured that the first and second arc-shaped outer shells are fixed after being adjusted to the required angle, so that the busbar trunking has the flexibility to bend.

[0010] Furthermore, the outer sidewall of the first arc-shaped conductive sheet is tightly attached to the inner sidewall of the second arc-shaped conductive sheet, and the centers of the first and second arc-shaped conductive sheets are on the same center.

[0011] By adopting the above technical solution, it is ensured that when the second arc-shaped conductive sheet moves in a circle on the first arc-shaped conductive sheet, the first arc-shaped conductive sheet and the second arc-shaped conductive sheet are in close contact, thus ensuring the conductive transmission of electricity.

[0012] Furthermore, the first and second arc-shaped outer shells are circumferentially and axially slidably connected.

[0013] By adopting the above technical solution, the stability of the second arc-shaped outer shell rotating on the first arc-shaped outer shell is ensured by the sliding connection.

[0014] Furthermore, an insulating filling layer is provided between the first straight conductive sheet and between adjacent first circular arc conductive sheets, and an insulating filling layer is provided between adjacent second straight conductive sheets and between adjacent second circular arc conductive sheets.

[0015] By adopting the above technical solution, the insulating filling layer can provide insulation protection for adjacent straight conductive sheet 1, adjacent arc conductive sheet 1, adjacent straight conductive sheet 2, and adjacent arc conductive sheet 2, avoiding short circuits caused by contact.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes the close contact between two arc-shaped conductive plates during their relative circular motion. This ensures that the two conductive plates remain in a state of mutual conductivity and connection when the included angle of the busbar trunking is adjusted. This avoids the problem of reduced conductivity caused by the need for cable connections when the positions of the two conductive plates change, thus guaranteeing the conductivity of the bent busbar trunking. By adjusting the included angle of the busbar trunking on-site, it can adapt to the requirements of the construction site, eliminating the need for customization. It is easy to meet and fit the corners of buildings, improving work efficiency.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model embodiment proposes a bent busbar trunking structure, including a busbar trunking body 1 and a busbar trunking body 2, wherein the busbar trunking body 1 is located on one side of the busbar trunking body 2.

[0027] The busbar trough 1 is composed of a straight outer shell 11 and an arc-shaped outer shell 12 that are fixedly connected to each other. The top of the straight outer shell 11 is fixedly connected to a cover shell 13 by screws. The bottom of the inside of the straight outer shell 11 is provided with a straight conductive plate 14 and a sealing platform 16. The straight conductive plate 14 is located on one side of the sealing platform 16. The bottom of the inside of the arc-shaped outer shell 12 is provided with an arc-shaped conductive plate 15. A mating plate 17 is provided on the outer wall of the sealing platform 16 away from the straight conductive plate 14. Both the mating plate 17 and the arc-shaped conductive plate 15 are electrically connected to the straight conductive plate 14. The arc-shaped conductive plate 15 and the straight conductive plate 14 protrude from the top of the arc-shaped outer shell 12 and the straight outer shell 11, respectively. The protruding arc-shaped conductive plate 15 can contact the subsequent arc-shaped conductive plate 25, thereby achieving conductivity through contact. An insulating pressure roller 6 is rotatably connected to the bottom of the inside of the arc-shaped outer shell 12 near the outer side of the arc-shaped conductive plate 15.

[0028] Busbar trough 2 consists of a straight outer shell 21 and an arc-shaped outer shell 22 that are fixedly connected to each other. The arc-shaped outer shell 12 and the arc-shaped outer shell 22 are circumferentially and axially slidably connected. This sliding connection ensures the stability of the arc-shaped outer shell 22's rotation on the arc-shaped outer shell 12. The bottom of the straight outer shell 21 is fixedly connected to a cover shell 23 by screws. The top interior of the straight outer shell 21 is provided with a straight conductive plate 24 and a sealing platform 26. The straight conductive plate 24 is located on one side of the sealing platform 26. A mating piece 27 is provided on the outer wall of the sealing platform 26 on the side away from the straight conductive plate 24. The top interior of the arc-shaped outer shell 22 is provided with an arc-shaped conductive plate 25. An insulating filling layer is provided between the straight conductive plates 14 and between adjacent arc-shaped conductive plates 15. An insulating filling layer is provided between adjacent straight conductive plates 24 and between adjacent arc-shaped conductive plates 25. An insulating filling layer is provided to insulate and protect adjacent straight conductive sheet 14, adjacent arc conductive sheet 15, adjacent straight conductive sheet 24, and adjacent arc conductive sheet 25, preventing short circuits caused by contact. Both the mating sheet 27 and the arc conductive sheet 25 are electrically connected to the straight conductive sheet 24. The outer wall of the arc conductive sheet 15 is tightly attached to the inner wall of the arc conductive sheet 25, and the centers of the arc conductive sheet 15 and the arc conductive sheet 25 are on the same circle. This ensures that when the arc conductive sheet 25 moves in a circle on the arc conductive sheet 15, the arc conductive sheet 15 and the arc conductive sheet 25 are in close contact, ensuring the conductive transmission of electricity. The insulating pressure roller 6 applies pressure to the arc conductive sheet 25 and limits its movement, ensuring that the arc conductive sheet 25 is tightly attached to the arc conductive sheet 15.

[0029] A bearing shaft 3 is provided at the center of the bottom of the inner part of the arc-shaped outer shell 12. The top of the bearing shaft 3 is rotatably connected to the arc-shaped outer shell 22. Several fastening holes 5 are axially and evenly spaced on the outer wall of the arc-shaped outer shell 12. A fastening plate 4 is provided on the outer wall of the arc-shaped outer shell 22. A screw is screwed into the inside of the fastening hole 5. A through hole is provided on one side of the outer wall of the fastening plate 4 so that the screw can pass through. By using the fastening plate 4 and the arc-shaped outer shell 12 to lock and fix, it can be ensured that the arc-shaped outer shell 12 and the arc-shaped outer shell 22 are fixed after being adjusted to the required angle, so that the busbar trunking has the flexibility to bend.

[0030] The specific implementation method is as follows: In order to adapt to the installation requirements of corners on the construction site, the included angle between busbar trough body 1 and busbar trough body 2 in the bent busbar trough is adjusted. Specifically, the arc shell 12 and arc shell 22 are rotated through the bearing shaft 3. The arc shell 22 slides in a circle on the arc shell 12. As the arc shell 22 rotates, the included angle between busbar trough body 1 and busbar trough body 2 is adjusted. When the required angle is reached, the screw passes through the fastening plate 4 and is screwed into the fastening hole 5 to fix the relative position between the arc shell 12 and arc shell 22, thereby making the busbar trough bend and have bendability.

[0031] When the second arc-shaped outer shell 22 rotates on the first arc-shaped outer shell 12, the second arc-shaped conductive plate 25 moves in a circular motion along with the first arc-shaped conductive plate 15. Due to the special arc structure of the second arc-shaped conductive plate 25 and the first arc-shaped conductive plate 15, the second arc-shaped conductive plate 25 and the first arc-shaped conductive plate 15 are in continuous close contact, thereby achieving conductivity. This ensures that when the angle between the first busbar trough body 1 and the second busbar trough body 2 is adjusted, the first docking plate 17 and the second docking plate 27 are electrically connected, thereby achieving conductivity.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
