[0027] The heat dissipation hole 6 can be set up to heat dissipation cable, conveniently reduce its temperature, through the bolt 8 perforation 54 through hole 7, and the locking nut 9 is sleeved on bolt 8 and is tightened, thereby conveniently installing fixed frame 1 and movable frame 2, and vice versa, conveniently disassembling movable frame 2, so that it is convenient to assemble.

[0028] As Figures 3-4As shown, the fixing mechanism 3 comprises a support 31, the lower end of the support 31 is fixedly connected with the inner side of the fixing frame 1, and is equidistantly distributed, the upper end of the support 31 is fixedly connected with a limiting seat one 32, the upper end of the movable frame 2 is equidistantly distributed with a plurality of groups of rotatingly installed rotating rods 33 on both sides, the top of the rotating rod 33 is fixedly installed with a knob 34, the lower end of the rotating rod 33 is externally fixedly sleeved with a chain wheel one 35, the middle part of the movable frame 2 is rotatably installed with a plurality of groups of screw rods 36 on both sides, the top of the screw rod 36 is fixedly installed with a chain wheel two 37, the exterior of the chain wheel one 35 and the chain wheel two 37 is sleeved with a chain 38 which is engaged, the upper end of the movable frame 2 is fixedly installed with a plurality of groups of equidistantly distributed installation covers 39.

[0029] The two groups of chain wheels and the chain 38 are located inside the installation cover 39, the top of the rotating rod 33 extends out of the inside of the installation cover 39.

[0030] The lower end of the screw rod 36 is externally sleeved with a threaded sleeve 310 which is threadedly connected, the bottom of the threaded sleeve 310 is fixedly installed with an embedded seat 311, the bottom of the embedded seat 311 is fixedly installed with a limiting seat two 312, the top inner wall of the movable frame 2 is equidistantly distributed with a plurality of groups of fixedly installed guide rods 313, the exterior of the guide rod 313 is slidably sleeved with a limiting ring rod 314.

[0032] The limiting seat one 32 and the limiting seat two 312 facilitate the compression of the cable, so that it is not easy to loosen, and the arrangement is more regular. When the threaded sleeve 310 moves up and down, it drives the limiting ring rod 314 to slide along the guide rod 313. The component can limit the threaded sleeve 310 and also can promote its movement stability;

[0033] The cable can be segmented and compressed by the plurality of limiting seat one 32 and limiting seat, so that it can prevent the cable from gathering together, and also facilitate the later staff to quickly check it. The installation cover 39 can shield the chain wheel and the chain 38 inside, preventing them from being exposed and damaged.

[0034] As shown in the figure, Figure 5 The installation assembly 5 comprises a support rod 51, the lower end of the support rod 51 is fixedly connected with the top of the bottom frame 4 at both ends, a plurality of groups of equidistantly distributed screw holes 52 are formed in the support rod 51, the exterior of the support rod 51 is slidably sleeved with a positioning column 53, a through hole 54 is formed in the front side of the lower end of the positioning column 53, a locking rod 55 is movably inserted into the inside of the through hole 54, and an installation plate 56 is fixedly installed on the top of the positioning column 53.

[0035] The locking rod 55 is threadedly connected with the screw hole 52.

[0036] The working principle of this modular cable tray with a fixed structure will be explained in detail below.

[0037] like Figures 1-5 As shown, when using this modular cable tray with a fixed structure, the cables to be fixed are placed in the limiting seat 32, and then the movable frame 2 is installed on the fixed frame 1. At this time, the bolt 8 can be passed through the through hole 7, and the locking nut 9 can be put on it and tightened, thus completing the installation of the fixed frame 1 and the movable frame 2. Then, the knob 34 can be rotated, so that the knob 34 drives the rotating rod 33 to rotate. The rotating rod 33 drives the first sprocket 35 to rotate. At this time, the first sprocket 35 drives the second sprockets 37 on both sides to rotate through the meshing chain 38. The second sprockets 37 drive the screw 36 to rotate. The screw 36 drives the threaded cylinder 310 to move downward. The threaded cylinder 310 drives the second limiting seat 312 to move synchronously through the fitting seat 311, thereby clamping and fixing the cable, making the cable position more secure and the arrangement more regular. By loosening and removing the locking rod 55 from the screw hole 52, the positioning post 53 can be moved up and down to adjust the distance between the fixing frame 1 and the ground. After adjustment, the locking rod 55 can be inserted into the screw hole 52 again and tightened to fix the positioning post 53, which facilitates the laying of the cable.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
