Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and more specifically, it relates to a cable tray that is easy to fix cables. Background Technology

[0002] Cable trays, as a key infrastructure in power engineering and building intelligent systems, play a vital role in supporting, fixing, and protecting cables. They come in various structural forms, including trough-type, tray-type, and ladder-type, and feature modular design, flexible installation, and convenient maintenance. They are widely used in industrial plants, data centers, commercial buildings, and other scenarios. Traditional cable trays primarily separate cables through physical space, but lack active fixing mechanisms. This makes cables prone to displacement due to vibration, external forces, or their own weight during long-term use, leading to the following problems:

[0003] 1. Cable wear and safety hazards: Friction between cables and the inner wall of the cable tray or between adjacent cables will accelerate the wear of the outer sheath, increasing the risk of short circuits and leakage, especially in environments with frequent vibrations;

[0004] 2. Insufficient heat dissipation: When cables are densely arranged, traditional cable trays lack effective heat dissipation structures. Heat accumulation may accelerate insulation aging and affect power supply stability.

[0005] Therefore, it is necessary to design a cable tray that can easily secure cables to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a cable tray that is easy to fix cables, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable tray for easy cable fixing, comprising a housing, with multiple movable seats slidably connected inside the housing, and multiple fixing mechanisms slidably connected to the surfaces of the movable seats. Each fixing mechanism includes an upper clamp and a lower clamp. A sliding groove is formed on the surface of the movable seat. A slider is fixedly connected to the bottom end of the lower clamp and slidably connected inside the sliding groove. Multiple springs are fixedly installed on the inner bottom surface of the lower clamp, and a lower clamp is fixedly connected to the top end of each spring. A screw hole is formed on the top surface of the upper clamp, and a screw is threadedly connected to the inner wall of the screw hole. The lower end of the screw is rotatably connected to the upper clamp.

[0008] Preferably, the top surface of the lower clamp is symmetrically fixedly connected with a plurality of fixing pins, the bottom surface of the upper clamp is symmetrically provided with a plurality of fixing holes for inserting the fixing pins, the outer wall of the fixing pin is sleeved with a heat dissipation plate, and the side of the heat dissipation plate is provided with a through hole for passing through the fixing pin.

[0009] Preferably, the inner wall of the outer shell is symmetrically fixed with two tenons, and both ends of the movable seat are provided with mortises for sliding connection of the tenons.

[0010] Preferably, the inner bottom surface of the housing has multiple heat dissipation holes, which are arranged in a rectangular array on the inner bottom surface of the housing.

[0011] Preferably, a top plate is snapped onto the top surface of the outer shell, and multiple buckles are symmetrically fixedly connected to the top surface of the outer shell. Multiple slots for snapping the buckles are symmetrically opened on the bottom surface of the top plate. A fixing plate is fixedly connected to both ends of the top plate, and mounting holes are opened on the surface of the fixing plate.

[0012] Preferably, both the upper clamp and the lower clamp are concave, and both the upper clamp and the lower clamp are arc-shaped.

[0013] This utility model provides a cable tray that facilitates cable fixing, and has the following beneficial effects:

[0014] This utility model, by setting an upper clamp and a lower clamp, has the lower clamp slidably connected to the surface of the movable base via a slider at its bottom end. The number of lower clamps can be increased or decreased according to the number of cables to be placed, improving the planning of cable placement. The cable is placed on the inner wall of the lower clamp, and a fixing pin is inserted into the fixing hole to connect the upper and lower clamps. Rotating the screw moves the upper clamp downwards, causing its inner wall to press against the outer wall of the cable. The lower clamp utilizes the elasticity of a spring at its bottom end to ensure its inner wall always presses against the outer wall of the cable, thus achieving a clamping and fixing effect and improving the stability of the cable.

[0015] 2. This utility model, by setting a heat dissipation plate and using through holes to pass through fixing pins, realizes the connection between multiple lower clamps, avoids the lower clamps sliding on the surface of the moving seat and causing shaking, which causes friction between cables, resulting in wear and safety hazards. In addition, the heat dissipation plate can dissipate the heat generated by the cables themselves in the clamp, thus improving heat dissipation. Attached Figure Description

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a cable tray for easy cable fixing, including a housing 1, with multiple movable seats 2 slidably connected inside the housing 1, and multiple fixing mechanisms slidably connected to the surface of the movable seats 2. The fixing mechanisms include an upper clamp 5 and a lower clamp 4. A sliding groove 3 is opened on the surface of the movable seat 2. A slider 401 is fixedly connected to the bottom end of the lower clamp 4. The slider 401 is slidably connected inside the sliding groove 3. Multiple springs 402 are fixedly installed on the bottom surface of the lower clamp 4. The springs 402 provide adaptive clamping through pre-compression force to adapt to different cable diameters. A lower clamp 403 is fixedly connected to the top end of the spring 402. A screw hole 501 is opened on the top surface of the upper clamp 5. A screw rod 502 is threadedly connected to the inner wall of the screw hole 501. The lower end of the screw rod 502 is rotatably connected to the upper clamp 503.

[0025] By setting an upper clamp 5 and a lower clamp 4, the lower clamp 4 is slidably connected to the surface of the movable seat 2 via a slider 401 at its bottom end. The number of lower clamps 4 can be increased or decreased according to the number of cables to be placed, thereby improving the planning of cable placement. The cable is placed on the inner wall of the lower clamp 403, and the upper clamp 5 and the lower clamp 4 are connected by inserting a fixing pin 404 into the fixing hole 504. By rotating the screw 502, the upper clamp 503 is moved downward, so that the inner wall of the upper clamp 503 abuts against the outer wall of the cable. The lower clamp 403 uses the elastic effect of the bottom spring 402 to keep the inner wall of the lower clamp 403 abutting against the outer wall of the cable, thereby achieving the effect of clamping and fixing, thus improving the stability of the cable.

[0026] The top surface of the lower clamp 4 is symmetrically fixedly connected with multiple fixing pins 404, and the bottom surface of the upper clamp 5 is symmetrically provided with multiple fixing holes 504 for inserting the fixing pins 404. The outer wall of the fixing pin 404 is sleeved with a heat sink 6, and the side of the heat sink 6 is provided with a through hole 601 for passing through the fixing pin 404.

[0027] By setting up a heat sink 6 and using through holes 601 to pass through fixing pins 404, the connection between multiple lower clamps 4 is realized, which avoids the lower clamps 4 sliding on the surface of the moving seat 2 and causing shaking, which would cause friction between the cables, resulting in wear and safety hazards. In addition, the heat sink 6 can dissipate the heat generated by the cables themselves in the clamp, thus improving heat dissipation.

[0028] Two tenons 7 are symmetrically fixed on the inner wall of the outer shell 1, and mortises 8 for sliding connection of the tenons 7 are opened at both ends of the movable seat 2.

[0029] By setting the tenon 7 and connecting the tenon 7 with the mortise 8, the movable seat 2 is slidably connected to the bottom surface inside the outer shell 1. Multiple movable seats 2 can be placed as needed, and the spacing between the multiple movable seats 2 can be adjusted by sliding to keep the cable in a straight state, avoiding damage caused by the cable rubbing against the bottom surface inside the outer shell 1, thus improving the safety and neatness of the cable.

[0030] Multiple heat dissipation holes 14 are provided on the inner bottom surface of the outer casing 1. The diameter of the heat dissipation holes 14 is 5-10mm and the spacing between the holes is 15-20mm. The multiple heat dissipation holes 14 are arranged in a rectangular array on the inner bottom surface of the outer casing 1.

[0031] The top surface of the outer shell 1 is snapped with a top plate 9. Multiple buckles 10 are symmetrically fixedly connected to the top surface of the outer shell 1. Multiple slots 11 for snapping with buckles 10 are symmetrically opened on the bottom surface of the top plate 9. A fixing plate 12 is fixedly connected to both ends of the top plate 9. Mounting holes 13 are opened on the surface of the fixing plate 12.

[0032] Both the upper clamp 5 and the lower clamp 4 are concave, and both the upper clamp 503 and the lower clamp 403 are arc-shaped.

[0033] The specific usage and function of this embodiment are as follows: By connecting the tenon 7 and the mortise 8, the movable seat 2 is slidably connected to the inner bottom surface of the outer casing 1. Multiple movable seats 2 are placed as needed, and the spacing between the multiple movable seats 2 is adjusted by sliding to keep the cable straight, preventing the cable from rubbing against the inner bottom surface of the outer casing 1 and causing damage. The through hole 601 passes through the fixing pin 404 to realize the connection between the multiple lower clamps 4, preventing the lower clamps 4 from sliding on the surface of the movable seat 2 and causing shaking, which would cause friction between the cables, resulting in wear and safety hazards. In addition, the heat dissipation plate 6 can dissipate the heat generated by the cable itself in the clamp. The lower clamps 4 are connected by... The slider 401 at the bottom is slidably connected to the surface of the movable seat 2, thereby increasing or decreasing the number of lower clamps 4 according to the number of cables to be placed, improving the planning of cable placement. The cable is placed on the inner wall of the lower clamp 403, and the fixing pin 404 is inserted into the fixing hole 504 to connect the upper clamp 5 and the lower clamp 4. By rotating the screw 502, the upper clamp 503 is moved downward, so that the inner wall of the upper clamp 503 abuts against the outer wall of the cable. The lower clamp 403 uses the elastic effect of the bottom spring 402 to keep the inner wall of the lower clamp 403 abutting against the outer wall of the cable, thereby achieving the effect of clamping and fixing, thus improving the stability of the cable.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
