The cable tray with isolation grooves includes a cable tray shell. Multiple sliding plates are symmetrically fixedly installed on the inner walls of both sides of the cable tray shell. Sliders are slidably installed on the corresponding multiple sliding plates. Multiple groove plates are fixedly installed on the corresponding multiple sliders at one end close to each other.

[0004] Although it achieves the advantages of the cable tray with isolation groove provided by this utility model, such as easy and orderly placement of cables and convenience for subsequent maintenance and cable replacement;

[0005] However, this does not solve the problem that existing cable trays are not convenient for flexible adjustment and installation, nor are they conducive to fixing and isolating cables, thus affecting the flexibility of cable tray installation and the safety of cables during use. Utility Model Content

[0006] The purpose of this utility model is to provide a cable tray with an isolation groove to solve the problems mentioned in the background art, such as the inconvenience of cable trays in flexibly adjusting and installing cable trays, the difficulty in fixing and isolating cables, and the impact on the flexibility of cable tray installation and the safety of cables during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable tray with isolation grooves, comprising a tray body and a support frame. The tray body has multiple sets of support frames installed at equal intervals inside. Each support frame has multiple sets of grooves at equal intervals at its top end. Each groove has an arc-shaped block inside, and the arc-shaped block is slidably connected to the groove. Each support frame has multiple sets of arc-shaped grooves at equal intervals on its sidewalls. Each arc-shaped block has a sliding bolt on its sidewall, and the sliding bolt is slidably connected to the arc-shaped groove. The tray body has two sets of mounting frames outside. Each mounting frame has a support arm inside.

Each arc-shaped block 6 has a sliding bolt 5 installed on its side wall, which is slidably connected to the arc-shaped groove 4. Next, two sets of mounting brackets 15 are provided on the outside of the cable tray body 1. Each mounting bracket 15 is provided with a bearing arm 16 inside. A right linkage shaft 14 is installed at the end of the bearing arm 16 near the mounting bracket 15. The bearing arm 16 is movably connected to the mounting bracket 15 through the right linkage shaft 14. Each mounting bracket 15 below the bearing arm 16 is provided with a support arm 12 inside. A right movable shaft 13 is installed at the end of the support arm 12 near the mounting bracket 15. The support arm 12 is movably connected to the mounting bracket 15 through the right movable shaft 13.

[0026] First, install the mounting bracket 15 to the wall using expansion bolts. When it is necessary to adjust the installation height and angle of the cable tray body 1, first unscrew the locking pin 20 from the inside of the connecting block 19. Then, rotate the bearing arm 16. The bearing arm 16 rotates around the right linkage shaft 14, which drives the left linkage shaft 11 to slide inside the slide groove 17. The left linkage shaft 11 drives the support arm 12 to rotate around the right movable shaft 13. The support arm 12 drives the adjusting bracket 21 to move downward through the left movable shaft 10. The support arm 12 drives the connecting block 19 downward through the hinge shaft 18. After moving and adjusting to the corresponding height, reinsert the locking pin 20 into the interior of the adjusting bracket 21 and the connecting block 19, and tighten the locking pin 20 to fix the adjusting bracket 21 and the connecting block 19. Then loosen the locking bolt 8, rotate the connecting bracket 3, and the connecting bracket 3 rotates inside the U-shaped bracket 9 with the locking bolt 8 as the axis. After adjusting the connecting bracket 3 to the corresponding angle, tighten the locking bolt 8. Then install the cable tray body 1 onto the surface of the connecting bracket 3 to complete the installation of the cable tray. This achieves convenient and flexible adjustment and installation of the cable tray, and improves the flexibility of cable tray installation.

[0027] The exterior of the mounting bracket 15 is provided with an adjustment bracket 21, and the end of the bearing arm 16 near the adjustment bracket 21 is movably mounted with a left linkage shaft 11.

[0028] The side walls of the support arm 12 are all equipped with sliding grooves 17, and the left linkage shaft 11 is slidably connected to the sliding grooves 17.

[0029] Each end of the support arm 12 near the adjustment frame 21 is equipped with a left movable shaft 10, and the support arm 12 is movably connected to the adjustment frame 21 through the left movable shaft 10.

[0031] Locking bolts 8 are installed on the side walls of the U-shaped frame 9, and the locking bolts 8 pass through the U-shaped frame 9 and the connecting frame 3;

[0032] Multiple sets of cables are laid sequentially in the grooves 7 on the surface of the support frame 2. The grooves 7 isolate the cables. The sliding bolt 5 slides inside the arc-shaped groove 4, which drives the arc-shaped block 6 to slide inside the groove 7. The arc-shaped block 6 slides out from inside the groove 7 and contacts the top of the support frame 2. The arc-shaped block 6 and the grooves 7 on the surface of the support frame 2 form a closed loop, thereby limiting and fixing the cables to the support frame 2 to prevent them from loosening. This facilitates the fixing and isolation of the cables, prevents the cables from catching fire due to excessive distance, and improves the safety of the cables during use.
