The purpose of the present invention is to provide a cable tray capable of improving strength while reducing time for assembling and installing a traditional cable tray. The cable tray according to the present invention comprises: multiple side rails; and an inner coupling part combined with the inner side of the side rails and an outer coupling part combined with the outer side of the side rails, as a means for connecting the side rails. The inner coupling part includes: an inner body; multiple connectors formed on the inner body to protrude; and a rotational shaft formed with a size to protrude after passing through a hole formed on the side rails. The outer coupling part includes: an outer coupling part body having a rotational shaft inserting hole into which the rotational shaft protruding after passing through the side rails can be inserted; and multiple coupling links bent at a predetermined angle while extending from the outer coupling body. Each of the coupling links is formed with a shape to be inserted into each of the connectors by the rotation of the outer coupling part. |
