Description

Technical Field

[0001] This utility model relates to the field of cable tray structure technology, and in particular to a low-smoke, halogen-free, flame-retardant PP cable tray structure. Background Technology

[0002] Cable trays, also known as wiring ducts, distribution ducts, or cable management ducts (the names vary depending on the region), are electrical tools used to neatly organize and fix power cords, data cables, and other cables to walls or ceilings. Depending on the material, cable trays are classified into various types, commonly including environmentally friendly PVC cable trays, halogen-free PPO cable trays, halogen-free PC / ABS cable trays, and metal cable trays such as steel and aluminum.

[0003] A reinforced low-smoke halogen-free wiring trough, patent number CN202222001477.4, includes: a trough body, a cover, a fixing block, and a clamping mechanism. The cover is horizontally and detachably mounted on the top of the trough body. Side plates are vertically fixed to both sides of the upper surface of the trough body. The upper surfaces of the two side plates are partially recessed along the length of the trough body, forming multiple arc-shaped outlet slots adapted to the wires. This design solves the problem of poor strength in existing wiring trough structures. During subsequent wire repairs, whether targeting one or more wires, it is necessary to remove the cover from the frame opening, move the desired wire or wire upwards along the outlet holes, and pull it out from the frame opening, which is cumbersome and inconvenient for repairs.

[0004] However, the above-mentioned patent still has the following defects in actual operation: it uses the elastic force of the spring to clamp the cable, but the clamping of the spring is elastic clamping, and the clamping force it forms is not firm enough, which can easily lead to loosening.

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] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a low-smoke, halogen-free, flame-retardant PP cable tray structure, comprising: a tray body 1, which is U-shaped, with four fixing blocks 3 embedded and fixedly installed at the top of the tray body 1. The top of the four fixing blocks 3 is fixedly connected to a top cover 2, and a clamping assembly is provided at the bottom of the top cover 2. The clamping assembly includes multiple clamping blocks 13, which are located at the bottom of the top cover 2 near the front and rear sides. A round rod 11 is fixedly connected to the top of each clamping block 13. Multiple threaded grooves 9 are opened at the top of the tray body 1. A round hole 10 is opened at the bottom of the inner wall of each threaded groove 9. The top of the round rod 11 passes through the corresponding round hole 10 and is movably connected to a threaded block 16. The threaded block 16 is threadedly connected to the inner cavity of the threaded groove 9. A spring 12 is movably installed on the outside of the round rod 11. The two ends of the spring 12 are fixedly connected to the top of the clamping block 13 and the bottom of the top cover 2, respectively. Multiple sets of evenly distributed embedded grooves 8 are opened at the top of the tray body 1.

[0024] Specifically, first, pull the two corresponding threaded blocks 16 upwards, causing the threaded blocks 16 to move the corresponding round rod 11. The round rod 11 then moves the clamping block 13 upwards, while the clamping block 13 compresses the top spring 12. Next, pass the cable through the two corresponding embedded slots 8 in sequence, and release the threaded blocks 16, allowing them to reset under the elastic force of the spring 12. This allows the clamping block 13 to be positioned on the top surface of the cable. Then, screw the threaded blocks 16 into the threaded groove 9, achieving a threaded connection between the threaded blocks 16 and the inner wall of the threaded groove 9. This ensures that the round rod 11 remains stable and does not wobble, improving the stability of the cable clamping operation.

[0025] When the threaded block 16 is screwed into the threaded groove 9, it will continue to push the clamping block 13 downwards for a distance, so that the clamping block 13 can press the top of the cable surface and cooperate with the embedded groove 8 to achieve clamping and positioning of the cable.

[0026] In this embodiment, as Figure 4 As shown; the clamping assembly also includes multiple handwheels 17, which are respectively fixedly connected to the top of multiple threaded blocks 16.

[0027] Specifically, the multiple handwheels 17 facilitate the application of force to the threaded block 16, controlling its upward movement and rotation.

[0028] In this embodiment, as Figure 4 As shown, multiple handwheels 17 are cylindrical in shape, and multiple anti-slip textures 18 are provided on the outer wall of each handwheel 17.

[0029] Specifically, the use of multiple anti-slip textures 18 makes it easier to apply force to the handwheel 17, lifting it upwards or turning it.

[0030] In this embodiment, as Figure 4 As shown; a round shaft 15 is fixedly installed at the top of the round rod 11, and the top of the round shaft 15 passes through the threaded block 16 and is rotatably connected to the threaded block 16.

[0031] Specifically, the bottom of the threaded block 16 and the top of the round rod 11 are rotated using the round shaft 15, so that the threaded block 16 will not rotate synchronously with the round rod 11 when it rotates, thus avoiding the spring 12 from being synchronously twisted and compressed, and improving stability.

[0032] In this embodiment, as Figure 4 As shown, the bottom of the clamping block 13 is arc-shaped, and a protective pad 14 is fixedly installed on the inner wall of the arc surface of the clamping block 13.

[0033] Specifically, the protective pad 14 is used to protect the outer surface of the cable, and the protective pad 14 can deform during the clamping process to provide a travel distance for the threaded connection of the threaded block 16.

[0034] In this embodiment, as Figure 1 As shown; two docking rods 6 are fixedly connected to the left side of the tank body 1, and two docking holes 7 are opened on the right side of the tank body 1.

[0035] Specifically, when splicing two or more cable tray structures, the docking rod 6 on the outer wall of one tray 1 can be inserted into the docking hole 7 on the outer wall of another tray 1 to achieve the initial docking operation.

[0036] In this embodiment, as Figure 1 As shown; the top of the cover 2 has two splicing grooves 4, and splicing holes 5 are provided on the bottom of the inner wall of each of the two splicing grooves 4.

[0037] Specifically, after the initial docking of two or more cable tray structures is completed, the prepared splicing plate is embedded into the two splicing slots 4, and screws are driven into the splicing holes 5 on the splicing plate to fix the splicing plate to the splicing slots 4, thereby further fixing the two cable tray structures.

[0038] In this embodiment, as Figure 1 As shown; the central angle of the embedded slot 8 is set to 270°.

[0039] Specifically, this design prevents cables located inside the embedding slot 8 from being easily removed from above, thus improving the cable clamping effect.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
