Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically relating to a busbar with flame-retardant function. 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] Busbar trunking is typically installed under each floor and between adjacent buildings. However, during installation, differences in the height of adjacent building floors and inconsistent installation heights of the supports for the busbar trunking can lead to a height difference between adjacent busbar trunking, making it difficult to precisely connect and fix the busbars together.

[0004] Therefore, a busbar trunking with flame-retardant function is proposed. Summary of the Invention

[0005] This utility model provides a busbar trunking with flame-retardant function, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a busbar trunking with flame-retardant function, including a busbar trunking body; a busbar trunking connector located on one side of the busbar trunking body; an outer conductive bar penetrating the outer wall of the busbar trunking connector; an inner conductive bar located inside the busbar trunking body; a contact conductive bar integrally formed on one side of the inner conductive bar, the contact conductive bar and the outer conductive bar being tightly fitted; an extrusion insulating roller rotating on the inner wall of the busbar trunking body near the outer side of the contact conductive bar and the outer conductive bar; an adjustment groove located at the center of one side of the busbar trunking body; a guide groove formed on the inner wall of the adjustment groove; a protective cover located on one side of the busbar trunking connector near the interior of the adjustment groove; a guide strip located on the outer wall of the protective cover; and two folded protective covers, one on the top and one on the bottom of the protective cover near the outer side of the outer conductive bar, respectively, the first folded protective cover being located on one side of the second folded protective cover, and one side of both the first and second folded protective covers being fixedly connected to the inner wall of the adjustment groove.

[0007] Furthermore, four fastening blocks are symmetrically arranged on the outer side walls of both the busbar trunking body and the busbar trunking connector, and through holes for bolts to pass through are provided on the outer side walls of the fastening blocks.

[0008] By adopting the above technical solution, it is easy to fix the busbar trunking body and the busbar trunking joint together, and it is easy to transport and store the busbar trunking.

[0009] Furthermore, a busbar trunking cover plate is provided on the top of the busbar trunking body, and the interior of the busbar trunking body is filled with a flame-retardant layer.

[0010] By adopting the above technical solution, the flame-retardant layer ensures the flame-retardant capability of the busbar trunking.

[0011] Furthermore, the inner conductive busbar and the contact conductive busbar form a T-shaped structure;

[0012] By adopting the above technical solution, the T-shaped structure can extend the contact surface of the contact busbar and the outer busbar, thereby ensuring full contact between the contact busbar and the outer busbar, so that the power transmission is stable when the busbar joint is adjusted in vertical height.

[0013] Furthermore, the guide bar is located inside the guide groove, and the guide bar and the guide groove are slidably connected;

[0014] By adopting the above technical solution, the busbar joint can move vertically on the busbar body through the cooperation of the guide bar and the guide groove, and the stability of the movement can be guaranteed.

[0015] Furthermore, the first and second folding protective covers are accordion covers;

[0016] By adopting the above technical solution and utilizing the folding capability of the bellows cover, one side of the busbar trunking body can be protected to prevent dust and moisture from entering the busbar trunking body.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model achieves height adjustment of the busbar trough connector by moving the busbar trough connector and the busbar trough body vertically and in a certain staggered state. This facilitates the connection of the busbar trough connector with the conductive busbar on the adjacent busbar trough. With the cooperation of the protective cover, the first folding protective cover and the second folding protective cover, one side of the busbar trough body is protected and sealed, preventing dust and moisture from entering the busbar trough body, preventing the spread of fire caused by spontaneous combustion of the busbar trough, and improving the flame retardant ability of the busbar trough itself.

[0027] Reference Figure 1-4 This utility model embodiment proposes a busbar trunking with flame-retardant function, including a busbar trunking body 1, a busbar trunking connector 2 provided on one side of the busbar trunking body 1, an outer conductive busbar 3 penetrating through the outer wall of the busbar trunking connector 2, one end of the outer conductive busbar 3 located inside the busbar trunking body 1, an inner conductive busbar 4 provided inside the busbar trunking body 1, and contact conductive busbars 5 integrally formed at both ends of the inner conductive busbar 4, the inner conductive busbar 4 and the contact conductive busbar 5 forming a T-shaped structure, the T-shaped structure can extend the contact surface of the contact conductive busbar 5 and the outer conductive busbar 3, so that the contact conductive busbar 5 and the outer conductive busbar 3 can fully contact each other, so that when the busbar trunking connector 2 is adjusted in vertical height, the power transmission is stable, the contact conductive busbar 5 and the outer conductive busbar 3 are tightly fitted, and the inner side wall of the busbar trunking body 1 is rotatably connected to both sides near the contact conductive busbar 5 and the outer conductive busbar 3, the pressure insulating roller 6 pressures the contact conductive busbar 5 and the outer conductive busbar 3 to make them contact and fit together, ensuring stable power transmission;

[0028] An adjustment groove 7 is provided on one side of the busbar trunking body 1. Two guide grooves 8 are symmetrically provided on the inner wall of the adjustment groove 7. A protective cover 9 is provided in the center of one side of the busbar trunking connector 2. Two guide bars 10 are symmetrically provided on the outer wall of the protective cover 9. The guide bars 10 are located inside the guide grooves 8, and the guide bars 10 and guide grooves 8 are slidably connected. Through the cooperation of the guide bars 10 and guide grooves 8, the busbar trunking connector 2 can move vertically on the busbar trunking body 1, ensuring the stability of the movement. Folded protective cover 11 and folded protective cover 2 12 are provided at the top and bottom of 9 near the outer side of the outer conductive busbar 3. Folded protective cover 11 is located on one side of folded protective cover 2 12, and the other side of folded protective cover 11 and folded protective cover 2 12 are fixed to the inner side wall of the regulating groove 7. Folded protective cover 11 and folded protective cover 2 12 are bellows covers. By utilizing the folding ability of the bellows cover, one side of the busbar trunking body 1 can be protected to prevent dust and moisture from entering the busbar trunking body 1.

[0029] Four fastening blocks 13 are symmetrically arranged on the outer side walls of both the busbar trunking body 1 and the busbar trunking connector 2. Through holes for bolts to pass through are opened on the outer side walls of the fastening blocks 13. A busbar trunking cover plate 14 is provided on the top of the busbar trunking body 1, and the interior of the busbar trunking body 1 is filled with a flame-retardant layer. The flame-retardant layer ensures the flame-retardant ability of the busbar trunking and prevents spontaneous combustion inside the busbar trunking from causing a fire.

[0030] The specific implementation method is as follows: When the adjacent busbar trunking bodies 1 are hoisted and installed and then connected, if there is a height misalignment at the connection point of the conductive busbars, the height of the busbar trunking connector 2 on one of the busbar trunkings can be adjusted. Specifically, the bolts of the fastening blocks 13 on the busbar trunking body 1 and the busbar trunking connector 2 are removed, and the busbar trunking body 1 and the busbar trunking connector 2 are in an active state.

[0031] Guided by the guide bar 10 sliding within the guide groove 8, the protective cover 9 can move vertically and linearly within the adjustment groove 7. The busbar joint 2 and the busbar body 1 are misaligned in the vertical direction, enabling the adjustment of the height of the busbar joint 2. This facilitates the connection of the busbar joint 2 with the conductive busbars on its adjacent busbars. When the protective cover 9 moves within the adjustment groove 7, the folding protective cover one 11 and the folding protective cover two 12 expand and contract adaptively, protecting one side of the busbar body 1 and preventing dust and moisture from entering the busbar body 1.
