[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figure 1-4 The present invention provides a trough-type cable bridge, comprising two bridge bodies 1, the two bridge bodies 1 are arranged in parallel, a plurality of transition bridges 2 with successively decreasing sizes are arranged between the two bridge bodies 1, two adjacent transition bridges 2 are slidably sleeved, and two transition bridges 2 located on the sides are fixedly connected to the bridge bodies 1; a plurality of bottom plates 3 are fixedly connected inside the bridge bodies 1, the plurality of bottom plates 3 are arranged in parallel, and a plurality of limiting components for limiting the position of cables are fixedly installed on the bottom plates 3; a plurality of connecting rods 4 are respectively fixedly connected to the opposite side walls of the bridge bodies 1, the plurality of connecting rods 4 are arranged in parallel up and down, the length of the connecting rods 4 decreases with the increase of their height, and the ends of the connecting rods 4 are rotatably connected with layered components; a cover body 5 is detachably connected to the top of the bridge bodies 1. By setting the limit assembly, the cables at the bottom of the bridge body 1 can be stabilized and stabilized in the specified position, and then the cables of the same color can be layered using the layering assembly so that they are located at different heights for easy identification; after the limit assembly limits the cables, the stability of the cables in the bridge body 1 can be increased; at the same time, the neat arrangement of the cables also facilitates later inspection and maintenance. In addition, by setting a number of transition bridges 2 between the two bridge bodies 1, the angles of the two bridge bodies 1 can be changed as needed, so that the angles can be adjusted according to the installation environment during installation.

[0018] Further optimization scheme, the limit assembly includes a limit seat 6 fixedly connected to the bottom plate 3, a limit slot 7 is provided in the limit seat 6, two limit blocks 8 are slidably connected in the limit slot 7, the two limit blocks 8 and the bottom wall of the limit slot 7 are respectively provided with arc grooves adapted to the cable, a compression spring 9 is fixedly connected between the limit block 8 and the side wall of the limit slot 7, and a control assembly for limiting the sliding of the limit block 8 is installed in the limit slot 7. The two limit blocks 8 are used to clamp and limit the cable under the action of the compression spring 9, so that it is stable in the bridge frame body 1, and the control assembly can ensure the limiting effect of the limit block 8 to prevent the limit failure.

[0019] Further optimization scheme, the control component includes two receiving grooves 10 opened on the bottom wall of the limit groove 7, the two receiving grooves 10 are arranged corresponding to the two limit blocks 8, the bottom of the limit block 8 is fixedly connected to the limit plate 11, the limit plate 11 is slidably located in the receiving groove 10, the side wall of the limit groove 7 is rotatably connected to the limit rod 12, the end of the limit rod 12 is slidably connected to the movement rod 13, the movement rod 13 is contacted with the limit plate 11, an extrusion spring 14 is fixedly connected between the limit rod 12 and the bottom wall of the receiving groove 10, and the side of the limit block 8 away from the arc groove is fixedly connected to the baffle 15, and the baffle 15 is arranged corresponding to the limit rod 12. When the cable moves downward, the limit block 8 will be squeezed first, and the limit block 8 will drive the limit plate 11 to push the movement rod 13 during the sliding process, so that the movement rod 13 moves into the limit rod 12, and then after the cable completely enters between the two limit blocks 8, the limit block 8 moves to the middle to clamp the cable. At the same time, since the limit plate 11 pushes the moving rod 13 into the limit rod 12, when the limit plate 11 is reset, the moving rod 13 no longer contacts the bottom of the limit block 8, and thus moves to the baffle 15 under the action of the extrusion spring 14, thereby limiting the limit block 8 and preventing it from loosening and affecting the limiting effect on the cable.

[0020] Further optimization scheme, the layered assembly includes a rotating rod 16 rotatably connected to the connecting rod 4, and the top and bottom surfaces of the rotating rod 16 are respectively provided with grooves 17, and the grooves 17 are arranged corresponding to the arc grooves on the bottom wall of the limiting grooves 7. The grooves 17 on the rotating rod 16 close to the bottom plate 3 and the arc grooves surround a circular groove adapted to the cable, and the bottom surfaces of the remaining rotating rods 16 are fixedly connected with pads 18, and the height of the pads 18 is equal to the distance between the two connecting rods 4. The inner wall of the cover body 5 is fixedly connected with a rubber strip 19, and the rubber strip 19 abuts against the rotating rod 16 on the top side. The grooves 17 between the two adjacent layers of rotating rods 16 can limit the cables, stabilize them in the bridge frame body 1, and arrange them neatly. The rubber strip 19 can apply pressure to the rotating rods 16 on the top layer after the cover body 5 is covered, thereby ensuring the stability of the cables.

[0021] The working process of the present invention is as follows: when in use, the cover 5 is first opened and the rotating rod 16 is erected, and then the bottom layer of cables is put in, and the cables are placed between the two limit blocks 8. When the cables move downward, the limit blocks 8 are first squeezed, and the limit blocks 8 drive the limit plate 11 to push the moving rod 13 during the sliding process, so that the moving rod 13 moves into the limit rod 12, and then after the cable completely enters between the two limit blocks 8, the limit block 8 moves toward the middle to clamp the cable. At the same time, because the limit plate 11 pushes the moving rod 13 into the limit rod 12, when the limit plate 11 is reset, the moving rod 13 no longer contacts the bottom of the limit block 8, and thus moves to the baffle 15 under the action of the extrusion spring 14, so that the limit block 8 can be limited to prevent its relaxation from affecting the limiting effect on the cable. Then, the rotating rods 16 are lowered in sequence, so that the grooves 17 on the two adjacent rotating rods 16 limit the cables and make them arranged neatly. Then, the cover body 5 is buckled, and the rotating rods 16 are pressed by the rubber strips 19, so that the cables are stabilized in the bridge body 1 through the rotating rods 16. Then, after adjusting the angles of the two bridge bodies 1, the cables are installed in the other bridge body 1.
