Example Embodiment

[0023] The specific implementation of the present invention will be described below with reference to the drawings and embodiments:

[0024] Figure 1 to Figure 5 A specific embodiment of the present invention is shown, wherein figure 1 , figure 2 with image 3 Three embodiments, the basic structure is the same, figure 2 Compared with the first embodiment, the shown embodiment 2 only has more upper-layer connectors; image 3 Compared with the embodiment 1, the embodiment 3 shown only has a plurality of spare holes 6 on the horizontal extension wall of the C-shaped steel;

[0025] Such as figure 1 As shown, the present invention includes two C-shaped steels 1 with two openings facing each other. The C-shaped steel 1 includes vertical side walls and two horizontally extending walls at the upper and lower ends of the side walls; the side walls of the C-shaped steel 1 are opened along the length of the C-shaped steel. Connecting groove 3, the side wall of C-shaped steel 1 is provided with a plurality of weight reduction holes 4 at intervals along the height direction of the C-shaped steel;

[0026] The present invention also includes a plurality of connecting pieces for connecting two C-shaped steels 1, the plurality of connecting pieces are arranged along the length of the C-shaped steel, and each connecting piece includes a hollow connecting steel pipe 5, and the connecting steel pipes 5 are arranged in two Between the two C-shaped steels, connecting blocks 7 are made at the inner ends of the connecting steel pipe 5, and a through hole is formed on the connecting block 7 along the length of the connecting steel pipe; the connecting piece also includes a through hole that passes through the connecting block 7 and a connecting The groove 3 will connect the steel pipe 5 and the C-shaped steel to fasten the connection fastener.

[0027] In order to increase the assembly form of the present invention and to further reduce the weight of the entire cable tray, the connecting grooves 3 on the side wall of the C-shaped steel 1 are two connecting grooves 3 opened in parallel along the height direction of the side wall of the C-shaped steel 1.

[0028] Figure 4 A structure of the above-mentioned fastener is shown. Specifically, the fastener is the bolt 2, the through hole on the connecting block 7 is a threaded hole, and the screw 8 of the bolt 2 passes through the connecting groove 3 and then engages and rotates. Into the threaded hole of the connecting block 7.

[0029] Figure 5 Another structure of the above-mentioned fastener is shown. Specifically, the fastener is a double-ended stud 11 and a nut 10. Both ends of the double-ended stud 11 pass through the through hole of the connecting block 7 and connect at the same time. Slot 3, a nut 10 and a washer 9 are installed at the end of the stud 11.

[0030] Preferably, the above-mentioned spacers 9 are two, one is a flat spacer and the other is a spring spacer.

[0031] In order to meet the needs of some specific occasions, such as the need to limit the cable above the C-shaped steel, the above-mentioned connecting pieces are arranged at equal intervals between two C-shaped steels, and the connecting pieces are arranged below the C-shaped steel length direction. One row or the upper and lower rows arranged along the length of the C-shaped steel, which are respectively connected by the lower connecting groove of the C-shaped steel or at the same time by the upper and lower connecting grooves of the C-shaped steel; this structure is arranged above the cable tray The structure of the cover obviously reduces more weight.

[0032] Such as Figure 5 As shown, the horizontally extending wall of the C-shaped steel is provided with a plurality of spare holes 6 at intervals. On the one hand, the spare hole can facilitate the assembly of multiple cable trays, or the assembly of the cable tray with other connectors, and on the other hand, it can further reduce the weight of the entire cable tray.

[0033] Preferably, the weight reduction hole is a square hole or an oval hole, and the spare space 6 is a circular hole.

[0034] Preferably, the above-mentioned connecting steel pipe 5 is a square pipe.
