DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a closed cable tray that is easy to maintain.

[0031] Reference Figure 1The closed cable tray which is easy to maintain includes a tray body 1, a support plate 2 and a cover plate 3. The tray body 1 is U-shaped, and the inner wall of the tray body 1 is bent to form a plurality of partitions 11, and the plurality of partitions 11 are evenly distributed on the two opposite inner walls of the tray body 1; the support plate 2 is thin plate-shaped, and the two ends of each support plate 2 are respectively abutted against the upper sides of the two oppositely arranged partitions 11, and a plurality of support plates 2 are distributed along the opening direction of the tray body 1 to divide the tray body 1 into a multi-layer structure; the cover plate 3 covers the opening of the tray body 1.

[0032] Reference Figure 1 In the present application, due to the arrangement of multiple support plates 2, different types of cables can be arranged in layers, so subsequent maintenance and management are convenient. In addition, this design method can not only reduce the electromagnetic interference between different types of cables, but also allow the heat generated by the cables to diffuse more smoothly, thereby maintaining the stability and reliability of the cable system and improving the performance and service life of the cables.

[0033] Reference Figure 1 In order to further facilitate the maintenance of cables, the following settings are correspondingly arranged: the bridge body 1 is divided into multiple unit bridges 4 along the length direction, and one unit bridge 4 is divided into two unit half bridges 5. Each unit half bridge 5 is L-shaped, and the two unit half bridges 5 are hinged. The ends of the two unit half bridges 5 away from each other are detachably connected to the cover plate 3. Then, one of the unit half bridges 5 of one of the unit bridges 4 can be opened, so a certain area can be opened from the side along the length direction of the bridge body 1 to simultaneously perform maintenance work on cables at different heights in this area, thereby making the cable maintenance work simpler.

[0034] Reference Figure 1 and Figure 2 In order to realize the hinge connection between the two unit half-bridge frames 5 through a simpler structure, the following settings are correspondingly arranged: the unit half-bridge frames 5 are bent at one end close to each other to form a hinge tube 6, and a hinge shaft 61 is passed through the inner side of the hinge tube 6. One hinge shaft 61 passes through the hinge tube 6 of multiple unit bridge frames 4, and mounting rings 62 are threadedly sleeved at both ends of the hinge shaft 61. The side of the mounting ring 62 close to each other abuts against the end face of the hinge tube 6 to achieve the purpose of serially fixing multiple unit bridge frames 4. In addition, the unit bridge frame 4 can move along the axial direction of the hinge shaft 61, so the gap between two adjacent unit bridge frames 4 can also be opened for maintenance work, thereby further diversifying the practical operation method of the maintenance work and making it easier to perform maintenance work.

[0035] Reference Figure 1 and Figure 3In order to facilitate the release of the connection between the unit half-bridge frame 5 and the cover plate 3 and to achieve the purpose of quickly opening the internal space of the bridge frame body 1, the unit half-bridge frame 5 is magnetically connected to the cover plate 3. At the same time, in order to accurately connect multiple unit bridge frames 4 to the cover plate 3, the following settings are correspondingly provided. One of the long sides of the cover plate 3 is bent to form a limited flange 31. At the same time, the unit bridge frame 4 also has a corresponding special setting. For the convenience of description, the two unit half-bridge frames 5 in a unit bridge frame 4 are respectively provided as a fixed part 7 and an opening part 8, wherein the vertical outer surface of the fixed part 7 is magnetically connected to the limited flange 31 to locate the relative position between the cover plate 3 and the unit bridge frame 4, and the opening part 8 is bent at one end away from the fixed part 7 to form a connecting flange 81 parallel to the cover plate 3. The connecting flange 81 is magnetically connected to the surface of one side of the cover plate 3 close to the bridge frame body 1, so that the opening part 8 can be smoothly disconnected from the cover plate 3, thereby realizing stable installation of the bridge frame and convenient maintenance of subsequent cables.

[0036] Reference Figure 1 and Figure 2 Considering that multiple unit bridge frames 4 are connected in series only by a hinge shaft 61, in order to maintain the convenience of connection between the bridge frame body 1 and the cover plate 3, the following settings are correspondingly arranged: the portion of the fixing portion 7 close to the opening portion 8 is bent inward to form a stabilizing through groove 71, and the stabilizing through grooves 71 between multiple unit bridge frames 4 are connected, and a stabilizing rod 72 is passed through the stabilizing through groove 71. The cooperation between the stabilizing through groove 71 and the stabilizing rod 72 can be used to keep the multiple fixing portions 7 in a stable posture, so that the connection between the bridge frame body 1 and the cover plate 3 can be more convenient while facilitating the maintenance of the cables. In addition, the stabilizing rod 72 is a heat pipe structure, and the characteristics of the stabilizing rod 72 can be used to more fully dissipate the heat of the cables.

[0037] In addition, in this embodiment, in order to further promote the heat dissipation of the cables, the outer side of the partition 11 is in a gap structure to form a heat dissipation groove 12, and the heat dissipation groove 12 is filled with thermal conductive adhesive 13, so that the heat dissipation of each layer of cables can be promoted.

[0038] By adopting the above technical solution, the heat dissipation of the cables can be further enhanced while maintaining the bridge structure.

[0039] Reference Figure 1 and Figure 3When comprehensive maintenance work is required, the bridge frame body 1 needs to be completely opened, that is, all the opening parts 8 need to be opened. At this time, in order to continue to keep the support plate 2 in a layered structure, the following settings are correspondingly made. The end of the support plate 2 close to the partition 11 is magnetically structured so that it can be adsorbed by an external magnet and fixed on the inner surface of the fixed part 7. Therefore, when all the opening parts 8 are opened, multiple support plates 2 can still maintain layering. At the same time, in order to improve the layered stability of multiple support plates 2, the length of the partition 11 is one-quarter to one-third of the length of the support plate 2, so as to strengthen the stable layering of the support plate 2.

[0040] The implementation principle of the closed cable tray that is easy to maintain in the embodiment of the present application is: the setting of multiple support plates 2 allows different types of cables to be arranged in layers, so it is convenient for subsequent maintenance and management. In addition, this design method can not only reduce the electromagnetic interference between different types of cables, but also allow the heat generated by the cables to diffuse more smoothly, thereby maintaining the stability and reliability of the cable system and improving the performance and service life of the cables.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
