[0002] Cable trays are metal structures used to support and protect power and communication cables. They are widely used in various buildings and industrial facilities. They are mainly composed of brackets, supports, and mounting accessories. They can be divided into various structural forms such as trough, tray, and ladder. Cable trays need to be laid according to the distribution of cables, and T-shaped corners are often present. Existing trough-type cable trays are mostly bent at the T-shaped corners. The bends will form a relatively sharp corner line in the bridge trough. The contact between the corner line and the cable turning position does not match, which can easily increase the pressure at the contact point and damage the cable, posing a safety hazard.

[0020] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0021] As shown in the attached Figure 1-6 An inlaid bridge frame wire groove corner connection structure is shown, which includes three bridge frame main bodies 1 arranged in a "T" shape. The bridge frame main bodies 1 arranged in a "T" shape are spliced through a T-shaped transfer structure 13. The T-shaped transfer structure 13 includes an arc-shaped side plate 14, a bottom plate 15 and a straight-edge side plate 16. There are two arc-shaped side plates 14, which are respectively located on both sides of the vertical rod of the T-shaped transfer structure 13 and extend to one side of the cross rod of the T-shaped transfer structure 13 close to the vertical rod. The centers of the two arc-shaped side plates 14 are outside the T-shaped transfer structure 13. The straight-edge side plate 16 is located on the side of the cross rod of the T-shaped transfer structure 13 away from the vertical rod. A plurality of inwardly protruding rectangular protrusions 20 are arranged on the straight-edge side plate 16. Installation wings 17 extending inward are arranged at the top and bottom of the arc-shaped side plate 14 and the straight-edge side plate 16. The bottom plate 15 is fixedly riveted to the installation wings 17 at the bottom of the arc-shaped side plate 14 and the straight-edge side plate 16 through a plurality of rivets. Connection parts 18 matching and connecting with the bridge frame main body 1 are arranged at both ends of the arc-shaped side plate 14 and the straight-edge side plate 16. Bolt holes 19 for fixedly connecting with the bridge frame main body 1 are arranged on the connection parts 18.

[0022] 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 19 correspond one to one. After the end of the bridge main body 1 is embedded between the two corresponding connecting parts 18 of the T-shaped transition structure 13, bolts are used to match the mounting strip holes 2 and the bolt holes 19 to splice the bridge main body 1 and the T-shaped transition structure 13. The mounting strip holes 2 can realize fine-tuning of the bolt position, thereby improving the splicing capacity of the bridge main body 1. The bridge body 1 has a spherical structure reinforcement protrusion 3 protruding inward on the bottom surface, and a rectangular structure reinforcement protrusion 3 protruding inward is provided on the side walls on both sides. The side walls on each side are provided with an inward-protruding arc-shaped reinforcement rib 4 above and below the structure reinforcement protrusion 3. There are two arc-shaped reinforcement ribs 4 on each side. The entire bridge body 1 has four arc-shaped reinforcement ribs 4. The structural strength of the bridge body 1 is greatly improved by the arrangement of the structural reinforcement protrusion 3 and the reinforcement rib 4. The top of the side wall of the bridge body 1 is provided with The U-shaped reverse side structure 6 with an opening downward is formed by bending inward 90 degrees twice. The U-shaped reverse side structure 6 and the reinforcing 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 top inner side of the bridge body 1. 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 application, it is necessary to adjust the size of the hanger unit 8 according to the size of the bridge body 1. A suitable number of hanging units 8 are installed in each length. 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 portion 11 that matches the mounting slot 7. The two sides of the connecting seat 9 are slidably clamped with the two mounting slots 7 through the clamping portions 11, and the mounting slots 7 limit the movement of the clamping portion 11 in the non-axial direction; one end of the hanging bolt 10 is fixedly mounted on the connecting seat 9, and the other end extends upward and fixedly mounted to the floor slab. The bridge frame body 1 is hung and mounted below the floor slab through the hanger structure 5.

[0023] 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.

[0024] At the branch where the bridge structure needs to be branched, three sections of the bridge main body 1 are connected through the T-shaped transfer structure 13 to achieve the installation method of T-shaped setting. Due to the design of the arc-shaped side plate 14 being more consistent with the turning point of the cable, it can reduce the pressure on the cable and will not form a corner line, will not cause scratches to the cable skin, and reduce potential safety hazards.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
