Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention provides a fire-resistant cable tray, including a cable tray body 1, a bearing plate 3 installed on the bottom wall of the inner cavity of the cable tray body 1, two sets of placement holes 4 opened on the bearing plate 3, a top plate 5 installed at the upper middle part of the bearing plate 3, a limiting component 6 provided on the top plate 5, and a splicing component 2 provided on the cable tray body 1; by setting the splicing component 2, multiple cable tray bodies 1 can be quickly spliced ​​and installed, thereby ensuring the electrical connection and structural stability between the various parts of the cable tray, and the splicing is convenient and quick, enhancing flexibility; and when the cable is placed in the placement hole 4, the cable can be limited by the setting of the limiting component 6, thereby avoiding the cables from tangling and knotting, facilitating subsequent maintenance work;

[0025] The splicing assembly 2 includes a fixing block 23 installed at one end of the cable tray body 1. The fixing block 23 has insertion holes 24 at both the upper and lower ends. Two connecting blocks 21 are installed at the other end of the cable tray body 1. The ends of the two connecting blocks 21 are connected to an embedded plate 22. Two guide rods 25 are installed in the embedded plate 22. Two sliders 26 are slidably connected between the two guide rods 25. Inserts 27 are installed at the opposite ends of the two sliders 26. The inserts 27 are slidably connected to the embedded plate 22. Two sets of springs 28 are installed between the two sliders 26. During splicing, the two inserts 27 are pressed against each other. As the sliders 26 slide on the guide rods 25 and compress the springs 28, the inserts 27 slide into the embedded plate 22, thereby embedding the embedded plate 22 into the fixing block 23. Then, as the springs 28 return to their original position, the inserts 27 slide into the insertion holes 24, completing the splicing of the two cable tray bodies 1.

[0026] like Figure 2 As shown, in some embodiments, the insert 27 slides within the socket 24; this facilitates splicing.

[0027] like Figure 2 As shown, in some embodiments, the fixing block 23 has a U-shaped structure, and the embedding plate 22 is embedded in the fixing block 23; this facilitates guiding and splicing.

[0028] like Figure 4 As shown, in some embodiments, the limiting component 6 includes a groove 61 formed in the top plate 5. Two fixing rods 62 are installed in the groove 61, and a slide block 63 is slidably connected between the two fixing rods 62. Mounting plates 64 are installed at both ends of the slide block 63, and abutment plates 65 are installed at the bottom ends of the two mounting plates 64. A screw 66 is rotatably connected in the groove 61, and a rocker arm 67 is installed at the upper end of the screw 66. The screw 66 is threadedly connected to the slide block 63. By rotating the rocker arm 67, the screw 66 is rotated, causing the slide block 63 to slide up and down the fixing rods 62, and causing the abutment plate 65 to move down and approach the placement hole 4, thereby tightening and limiting the cable placed in the placement hole 4 to prevent entanglement.

[0029] like Figure 1 As shown, in some embodiments, the number of abutment plates 65 and placement holes 4 are the same and they are located in pairs in the same vertical direction; this facilitates the limiting of cable position.

[0030] like Figure 1 As shown, in some embodiments, the surface of the cable tray body 1 is uniformly coated with acrylic acid fire-retardant paint; the fire-retardant paint expands at high temperatures to form a dense char layer, isolating oxygen and preventing the spread of flames. This char layer can effectively prevent the fire from spreading to the inner cables, protecting the safety of the cable circuit.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
