Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Cable tray is a metal or non-metal structure used to support and protect cables. It is usually composed of brackets, cross arms, corner pieces and connectors, etc. It can be installed on the wall, ceiling or ground to fix the cables so that they will not collide with other equipment or structures or be damaged.

[0024] However, most of the existing bridges are of an integrated structure or a split structure installed by fasteners. The integrated structure bridge is not only inconvenient to transport and carry, but also difficult to adjust the length, resulting in certain limitations in installation. The split structure installed by fasteners is mostly spliced ​​by bolts and connectors, and during the splicing process, the two bridges need to be manually supported when fixing them to ensure the stability of the two spliced ​​bridges, which is time-consuming and labor-intensive.

[0025] Based on the limitations of the existing technology in the installation of the integrated bridge and the technical problems of the inconvenience caused by the current bolt splicing on the split structure bridge, please refer to Figure 1-Figure 3The utility model provides a lightweight polymer alloy cable bridge, which utilizes the closely distributed limiting mechanism 3 and connecting mechanism 4 when two adjacent bridge bottom grooves 1 are connected to each other, to achieve the effect of positioning first and then fixing, and completes the straight sequential connection of multiple bridge bottom grooves 1 on the same plane, meets the support of cables of multiple lengths, and can improve the practicality of the equipment. The cable bridge is composed of a bridge bottom groove 1 and a cover plate 2 combined and enclosed on the upper part of the bridge bottom groove 1, and the cover plate 2 is connected to the open sliding combination on the upper part of the bridge bottom groove 1. The two sides of the cover plate 2 are penetrated by the corresponding ends on the bridge bottom groove 1 to form corresponding connecting openings, and the combined connecting plate 9 is inserted in the opening. The cover plate 2 is closed at the top of the bridge bottom groove 1 by the connecting plate 9 inserted in the opening, which can be quickly assembled, and the exposed open assembly fixed cable on the upper part of the bridge bottom groove 1.

[0026] In order to quickly connect and combine two or more adjacent bridge bottom grooves 1, the open ends on both sides of the bridge bottom groove 1 in the technical solution are respectively installed with a limiting mechanism 3 and a connecting mechanism 4 for connecting two adjacent bridge bottom grooves 1 and cooperating with each other;

[0027] Furthermore, grooves are provided on the side and two end surfaces of the bridge bottom groove 1 near the limit mechanism 3, and the limit mechanism 3 is arranged in the groove. The specific structure is composed of a first mounting plate 31 assembled at the bottom of the groove, the first mounting plate 31 is fixed in the groove by screws, and the first mounting plate 31 is pulled and fixedly connected to the slider 32 by a traction spring 34, and the slider 32 is horizontally guided and connected at the upper and lower ends in the groove, and the end surface of the support plate integrally formed on the slider 32 is threaded and rotated to match the connecting screw rod 33, and the inner end surface of the slider 32 is vertically integrally formed with a baffle plate 35, and by rotating the screw rod 33, the slider 32 integrally formed on the support plate with the thread rotationally matched thereon moves horizontally under the limit of the upper and lower ends in the groove, moving outward in the positive direction and moving inward in the reverse direction, and the elastic pulling effect of the traction spring 34 provides a fixed support effect of the slider 32 in the groove;

[0028] Furthermore, a slot 5 is provided on the side opening of the baffle 35 near the bridge bottom groove 1 by turning, and in order to cooperate with the slot 5 for connection, a slot is opened on the other end of the bridge bottom groove 1 in the technical solution to assemble the connecting mechanism 4, and its specific structure is composed of an insert block 41 and a second mounting plate 43. The insert block 41 is arranged on the other side of the bridge bottom groove 1 relative to the limiting mechanism 3, and the shape of the insert block 41 is compatible with the inner groove of the slot 5. The open end of the side of the insert block 41 near the bridge bottom groove 1 is connected to the damping shock absorber 42 by a method including but not limited to bolt fixing. With the cooperation of the damping shock absorber 42 and the traction spring 34, the stability of the connection position is achieved. The end of the damping shock absorber 42 away from the insert block 41 is also connected to the end face of the second mounting plate 43 by a method including but not limited to bolt fixing. The outside of the second mounting plate 43 and the corresponding end face of the opening on the bridge bottom groove 1 are turned. A fixing groove is processed and the second mounting plate 43 is fixed to the bottom surface of the fixing groove with screws. Two or more bridge bottom grooves 1 are taken out, and the limiting mechanisms 3 and connecting mechanisms 4 at the proximal ends of the bridge bottom grooves 1 that are adjacent to each other are connected. First, the screw rod 33 in the limiting mechanism 3 is rotated to rotate the slider 32 in the outward groove, and then the plug 41 connected to the damping and shock absorbing component 42 is inserted into the slot 5 processed by turning to achieve the positioning between the two adjacent bridge bottom grooves 1. Then, the screw rod 33 is rotated again to move the slider 32 horizontally in the inner groove in the opposite direction, so that the baffle 35 integrally formed on the slider 32 is limited and closed at the external opening of the slot 5, thereby completing the sequential connection of the two adjacent bridge bottom grooves 1. In addition, when combining multiple bridge bottom grooves 1 to form an integral cable bridge of a certain length, the limiting mechanisms 3 or connecting mechanisms 4 at the corresponding ends are not fixed with screws.

The structural design of the groove 6 reduces the overall mass. At the same time, the inside and outside of the groove 6 are connected, so that the cables fixed in the cable tray have sufficient ventilation space to avoid fire or damage caused by overheating.

[0030] Among them, in order to facilitate cable management and effectively avoid the chaotic and disordered stacking of multiple cables fixed in the cable tray, a plurality of partition bars 7 are fixed at the same distance on the bottom surface of the inner cavity of the bridge bottom trough 1 in the technical solution, including but not limited to welding. The cable fixing area separated by the partition bars 7 on the bottom surface of the inner cavity of the bridge bottom trough 1 can be placed in an orderly manner. A plurality of elastic ropes 8 connected across are horizontally installed in the inner cavity of the bridge bottom trough 1. The elastic ropes 8 can be used to fix and limit the cables, prevent the cables from shifting, and effectively avoid the chaotic and disordered stacking of multiple cables.
