They primarily consist of brackets, supports, and mounting accessories, and are available in various structural styles, including trough, tray, and ladder. Existing trough-type cable trays often use corner bends at their upper and lower bends. This creates sharp corner lines within the cable tray trough, and the contact between the corner lines and the cable bends does not align, which can increase pressure at the contact point and damage the cables, posing a safety hazard.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-5The bridge structure shown is an arc-shaped bent structure, comprising two sections of bridge bodies 1 that are staggered up and down. The staggered bridge bodies 1 are spliced ​​by upper and lower transition structures 13. The upper and lower transition structures 13 include a transition base plate 14 and a side plate 15. The bending parts of the transition base plate 14 and the side plate 15 are both arc-shaped structures. The top and bottom of the side plate 15 are provided with inwardly extending mounting wings 16. The shape of the mounting wings 16 matches the shape of the transition base plate 14. The transition base plate 14 is fixed to the mounting wings 16 at the bottom of the side plate 15 by riveting with multiple rivets. Both ends of the side plate 15 are provided with connecting parts 17 that match the bridge body 1. The connecting part 17 is provided with four bolt holes 18 for fixed connection with the bridge body 1.

[0020] As a preferred embodiment, four mounting strip holes 2 are provided on both side walls of the ends of the bridge main body 1. The four mounting strip holes 2 are arranged in a quadrilateral and are respectively located at the four vertex corners of the quadrilateral. The mounting strip holes 2 and the bolt holes 18 correspond one to one and cooperate with the bolts to splice the bridge main body 1 and the upper and lower transfer structures 13. The mounting strip holes 2 can realize fine-tuning of the bolt position, thereby improving the fault tolerance and adaptability of the splicing of the bridge main body 1. The bottom surface of the bridge main body 1 is provided with a spherical structural reinforcement convex protruding inward. The side walls on both sides are provided with inwardly protruding rectangular structural reinforcement protrusions 3, and the side walls on each side are provided with an inwardly protruding arc-shaped reinforcement rib 4 above and below the structural reinforcement protrusion 3. There are two arc-shaped reinforcement ribs 4 on each side. The entire bridge body 1 has a total of four arc-shaped reinforcement ribs 4. The structural reinforcement protrusions 3 and reinforcement ribs 4 are greatly improved by the arrangement of the structural reinforcement protrusions 3 and reinforcement ribs 4. The top of the side wall of the bridge body 1 is provided with a U-shaped reverse edge knot with an opening downward formed by bending inward 90 degrees twice. Structure 6, the U-shaped reverse edge structure 6 and the reinforcement rib 4 at the top of the corresponding side cooperate to form a mounting slot 7, that is, two mounting slots 7 are provided on the inner side of the top of the bridge body 1, and the two mounting slots 7 are symmetrically arranged on the side walls of the bridge body 1. The top inner side of the bridge body 1 is equipped with a hanger structure 5 through the two mounting slots 7. In this embodiment, the hanger structure 5 includes two evenly distributed hanging units 8. In actual applications, it is necessary to install an appropriate number of hanging units 8 according to the length of the bridge body 1. The hanging unit 8 includes a connecting seat 9 and two hanging bolts 10. Both sides of the connecting seat 9 are provided with a clamping part 11 matching the mounting slot 7. Both sides of the connecting seat 9 are slidably clamped with the two mounting slots 7 through the clamping part 11, and the mounting slot 7 limits the movement of the clamping part 11 in the non-axial direction; one end of the hanging bolt 10 is fixedly installed on the connecting seat 9, and the other end extends upward and is fixedly installed to the floor slab. The bridge body 1 is hung and installed below the floor slab through the hanger structure 5.

[0021] When in use, the bridge structure provided in this embodiment is installed with a corresponding number of hanging units 8 according to actual needs. Based on design requirements, holes are drilled in the ceiling or structural beams using an impact drill and expansion bolt sleeves are inserted. A corresponding number of connecting blocks 9 are then clipped into the mounting slots 7 and slid to the corresponding positions. The hanging bolts 10 on the connecting blocks 9 are then tightened into the expansion bolt sleeves, thereby securing the bridge body 1 to the ceiling or below the structural beam. Because the hanging units 8 are installed inside the bridge body 1, when viewed from below, they are obscured by the bridge body 1, preventing the hanger structure 5 from being exposed, making the bridge structure more simple and beautiful in appearance.

[0022] At the place where the bridge structure needs to be bent and dislocated up and down, the two sections of the bridge body 1 are connected by the upper and lower adapter structures 13 to achieve the upper and lower dislocated installation. Since the bending part of the adapter base plate 14 is designed to be an arc structure, it is more consistent with the turning part of the cable, which can reduce the pressure on the cable and will not form a corner line, will not cause scratches on the cable surface, and reduce safety hazards.

[0023] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
