[0026] This utility model provides, for example Figures 1-6 The diagram shows an anti-electromagnetic interference aluminum alloy cable tray with a built-in shielding layer, including a fixed shell 1. A shielding layer body 15 is provided on the inner wall of the fixed shell 1. The shielding layer body 15 is provided to block electromagnetic radiation and interference. The shielding layer body 15 is made of metal or alloy, such as tin-plated copper or stainless steel. The fixed shell 1 is made of aluminum alloy, which has the characteristics of strong corrosion resistance.

[0027] In existing technologies, when using aluminum alloy cable trays, cables are typically placed directly inside the tray. This can lead to cable slippage and poor stability. To improve stability, a cover plate 2, shaped like an inverted U, is bolted to the top of the mounting housing 1. Multiple support blocks 3 are fixedly connected inside the mounting housing 1, evenly distributed along its length. Each support block 3 has a V-shaped groove 4 on its top, also evenly distributed along its length. Cables of different sizes can be placed inside the V-shaped grooves 4.

[0028] Considering that operators will pull the cable during installation, direct contact with the inner wall of the V-groove 4 would increase cable wear and require greater pulling force, increasing operator workload. To reduce wear, first square grooves 5 are provided on both inner walls of the V-groove 4. First guide posts 6 are rotatably connected inside the first square grooves 5, and the two first guide posts 6 are arranged in a V-shape. Specifically, when the cable is placed inside the V-groove 4, it rests on the two first guide posts 6. When the operator pulls the cable, it causes the first guide posts 6 to rotate inside the first square grooves 5, reducing cable wear and facilitating pulling.

[0029] To secure the cable, a clamp 9 is positioned above the V-shaped groove 4. The clamp 9 is inverted V-shaped, and second square grooves 10 are formed on the inner walls of both sides of the clamp 9. Second guide posts 11 are rotatably connected inside the second square grooves 10. A sliding plate 7 is slidably mounted inside the fixing shell 1. An elastic telescopic rod 8 is fixedly connected to the top of the clamp 9, and the top of the elastic telescopic rod 8 is fixedly connected to the sliding plate 7. The two second guide posts 11 are also inverted V-shaped distribution, and they abut against the top of the cable on both sides. When the operator pulls the cable, the second guide posts 11 will rotate inside the second square grooves 10, which can reduce cable wear and facilitate the operator's pulling.

[0030] By setting the first guide post 6 and the second guide post 11, cable wear is reduced, and the cable tray is easier for operators to pull, thus improving its practicality.

[0031] The top of the cover plate 2 has a circular groove, and a threaded rod 12 is rotatably connected inside the groove. The slide plate 7 has a threaded hole 13 that mates with the threaded rod 12. The top of the threaded rod 12 has a cross groove 14, which can be used with a screwdriver to rotate the threaded rod 12. The friction coefficient between the threaded rod 12 and the threaded hole 13 is suitable, preventing random rotation. In addition, a pin or other structure can be set to limit the threaded rod 12, improving the stability of use. This can be adjusted according to specific usage conditions.

[0032] After the cable placement is completed, cover plate 2 is placed on top of the fixed shell 1. Since cover plate 2 is inverted U-shaped, both ends of cover plate 2 abut against the outer walls of the top of the fixed shell 1, reinforcing and supporting the fixed shell 1 from the outside in. At the same time, slide plate 7 is inserted into the interior of the fixed shell 1, and both ends of slide plate 7 abut against the inner walls of the fixed shell 1, reinforcing and supporting the fixed shell 1 from the inside out. The cooperation of cover plate 2 and slide plate 7 improves the overall stability of the aluminum alloy cable tray structure.

[0033] After the cable adjustment is completed, rotate the threaded rod 12 so that the slide plate 7 slides downward inside the fixed shell 1. The elastic telescopic rod 8 retracts adaptively, and the clamp 9 is pressed against the top of the cable by the second guide post 11, so that the cable is positioned between the corresponding V-groove 4 and the clamp 9, thus completing the positioning of the cable and preventing the cable from sliding randomly.

[0034] Because the height of the clamp 9 is adjustable, it can fix cables of different sizes, improving the applicability of aluminum alloy cable trays.

[0035] Furthermore, with the cooperation of structures such as the V-groove 4 and the clamp 9, the multiple cables inside the fixed shell 1 are arranged in an orderly manner, avoiding accumulation, improving heat dissipation efficiency, and enhancing the safety of using aluminum alloy cable trays.
