[0023] Example

[0024] refer to Figures 1-4A cable tray for easy cable fixing includes a tray body 1, which includes a tray base plate 11. Side tray plates 12 are symmetrically arranged on both sides of the tray base plate 11. A connecting plate 13, parallel to the tray base plate 11, is provided above the tray base plate 11. Connecting plates 14 are symmetrically arranged on both sides of the connecting plate 13. Support columns 15 are symmetrically arranged on both sides of the bottom of the connecting plate 14. A drive threaded hole 131 is provided through the connecting plate 13. A drive threaded rod 132 is screwed into the drive threaded hole 131. A rotatable support column 132 is provided on the drive threaded rod 132 located at the connecting plate 13. The pressure plate 16 below the plate 13 has sliding grooves 161 on both sides to accommodate the support column 15. Several partition grooves 162 are opened through the pressure plate 16. A partition plate 17 is detachably installed in the partition groove 162. By setting the partition plate 17, the staff can adjust the number and position of the partition plate 17 according to the laying requirements of the construction site, thereby adjusting the laying space inside the cable tray body 1, and separating cables of different specifications and quantities to avoid all the cables inside the cable tray body 1 from being gathered together and tangled.

[0025] The cable tray base plate 11 has multiple positioning threaded holes 111 on its top end face, and positioning rods 112 are screwed into the positioning threaded holes 111. The partition plate 17 has a positioning groove 171 on its bottom end face for the positioning rods 112 to be inserted. By screwing the positioning rods 112 into the positioning threaded holes 111 of the cable tray base plate 11, and then aligning the positioning groove 171 of the partition plate 17 with the positioning rods 112 and inserting them from top to bottom, the partition plate 17 and the cable tray base plate 11 are initially connected and installed, which improves the connection strength between the partition plate 17 and the cable tray base plate 11.

[0026] Furthermore, the support column 15 is provided with symmetrical guide grooves 151 on both sides, and the inner wall of the sliding groove 161 is provided with a guide block 163 that can move up and down in the guide groove 151. The arrangement of the guide block 163 and the guide groove 151 improves the stability of the pressure plate 16 in vertical displacement.

[0027] Furthermore, the outer side wall of the support column 15 is provided with an installation groove 152, and the inner side wall of the cable tray side plate 12 is provided with an installation plate 121 that can be inserted into the installation groove 152. Through the arrangement of the installation plate 121 and the installation groove 152, the support column 15 and the cable tray side plate 12 are initially connected and installed.

[0028] Furthermore, the connecting plate 14 has first fixing holes 141 at both ends for inserting fixing bolts 122, and the cable tray side plate 12 has second fixing holes 123 that communicate with the first fixing holes 141. By screwing the fixing bolts 122 into the second fixing holes 123 and the first fixing holes 141, the connecting plate 14 is fixedly installed between the two cable tray side plates 12.

[0029] Furthermore, the bottom end face of the connecting plate 14 is provided with a snap-fit ​​groove 142 that corresponds one-to-one with the partition groove 162 and can press the top of the partition plate 17. The partition plate 17 is further pressed and fixed by the snap-fit ​​groove 142.

[0030] Furthermore, multiple heat dissipation holes 164 are provided through the pressure plate 16 between the two partition grooves 162. The heat dissipation holes 164 can promote air circulation, thereby improving the heat dissipation effect of the cable.

[0031] Furthermore, a drive handwheel 133 is provided at the top of the drive threaded rod 132 to facilitate the operation of the drive threaded rod 132 by the operator.

[0032] The working principle of this utility model:

[0033] First, according to the laying requirements of the construction site, screw the positioning rod 112 into the positioning threaded hole 111 of the cable tray base plate 11. Then, align the positioning groove 171 of the partition plate 17 with the positioning rod 112 and insert it from top to bottom, so that the partition plate 17 and the cable tray base plate 11 are initially connected and installed. Then, align the mounting groove 152 of the support column 15 with the mounting plate 121 in the cable tray side plate 12 and insert it from top to bottom. At the same time as insertion, the partition plate 17 is inserted into the partition groove 162 of the pressure plate 16, and the top of the partition plate 17 is also snapped into the connecting plate 14. Inside the snap-fit ​​groove 142, the first fixing hole 141 of the connecting plate 14 is connected to the second fixing hole 123 of the cable tray side plate 12. The fixing bolt 122 is screwed into the second fixing hole 123 and the first fixing hole 141, thereby fixing the connecting plate 14 between the two cable tray side plates 12. At the same time, the partition plate 17 is further pressed and fixed. Finally, the drive handwheel 133 is rotated to drive the drive threaded rod 132 to rotate, so that the pressure plate 16 moves downward until the bottom end face of the pressure plate 16 contacts the cable, thereby limiting the cable.
