[0021] As attached Figure 1 The utility model is shown as a through-ground cable bridge, including a plurality of troughs 1 connected along the cable laying direction, as shown in the attached Figure 2 As shown, the tank body 1 includes a bottom plate 11 and side plates 12 perpendicular to both sides of the bottom plate 11 and extending upward, and the top of the side plate 12 has a top plate 13 bent inward to improve the strength of the tank body 1. The bottom plate 11 is processed with a first mounting hole 111, and the side plate 12 is processed with a second mounting hole 122, which can be used to bundle and fix the cables placed in the tank body 1, and also facilitate the connection of the tank body 1 with the mounting bracket horizontally mounted on the wall, so that the tank body 1 is installed stably.

[0022] The two ends of the side plate 12 are respectively provided with a first mounting portion 14 and a second mounting portion 15 extending in the length direction. A front mounting hole 141 and a rear mounting hole 142 are processed on the first mounting portion 14. A center hole 151 and a plurality of side holes 152 surrounding the center hole 151 are processed on the second mounting portion 15. The center hole 151 is located at the center of the circle where the center of the side hole 152 is located. The distance between the front mounting hole 141 and the rear mounting hole 142 is equal to the distance between the center hole 151 and any side hole 152. The first mounting portion 14 and the second mounting portion 15 of the adjacent trough body 1 are connected. The front mounting hole 141 and the center hole 151 are connected by fasteners, and the rear mounting hole 142 and the side hole 152 are connected by fasteners. The same trough body 1 is used to extend the cable tray. As shown in the attached figure Figure 1 As shown, when the wiring is straight, the rear mounting hole 142 and the middle side hole 152 are aligned and installed so that the adjacent slots 1 are located on the same horizontal plane; Figure 4 As shown, when the height needs to be changed, it is only necessary to rotate the trough 1, align the rear mounting hole with the different side holes 152, rotate the trough 1 to a suitable angle, and then lock the fasteners to lay the cable bridge at a higher place. This structure uses a single trough 1 for installation, and does not require the use of multiple accessories of different specifications. It has high versatility, saves costs, has a simple structure, and is easy to install.

[0023] One of the first mounting portion 14 and the second mounting portion 15 has a stepped surface bent inward, and the front mounting hole 141, the rear mounting hole 142 or the center hole 151 and the side hole 152 are located on the stepped surface. In this embodiment, the first mounting portion 14 has a stepped surface, and the front mounting hole 141 and the rear mounting hole 142 are located on the stepped surface, so that when the adjacent trough bodies 1 are connected, the first mounting portion 14 is located on the inner side of the second mounting portion 15, so that the structure is more compatible and the installation is more appropriate.

[0024] The side holes 152 on the second mounting portion 15 are all located on the outside, and the angle formed by the line connecting the centers of any two side holes 152 and the center hole 151 on the same second mounting portion 15 is ≤180°, which facilitates the rotation and adjustment of the tank body 1 and avoids the generation of redundant invalid holes, making the structure more compact.

[0025] The utility model through-ground cable bridge also includes an optional crossbar 2, as shown in the attached Figure 3 As shown, both ends of the crossbar 2 have hanging mounting holes 21, and the inner sides of the hanging mounting holes 21 are respectively formed with plug plates 22 perpendicular to the crossbar 2. A plug hole 131 is processed on the top plate 13, and a through hole 121 is processed on the side plate 12. The crossbar 2 is passed through the through hole 121. The hanging mounting holes 21 at both ends of the crossbar 2 are connected to the suspension rod on the ceiling. When the crossbar 2 is subjected to an upward pulling force, the plug plates 22 are correspondingly inserted into the plug holes 131, making the overall structure more reliable and reducing the deformation of the trough body 1 when subjected to force. The use of the crossbar 2 can make the trough body adapt to different installation environments, with diversified installation methods and wide adaptability. The crossbar 2 is an integrally formed sheet metal part, which is stamped in one time, is easy to process, and saves materials.

[0026] The utility model has a simple structure and is easy to install and adjust. It does not require too many accessories for installation. It has good versatility and can adapt to different installation methods, making cable installation more convenient and reliable.
