A multi-layer cable tray is a multi-layered bridge-like structure made of metal or non-metallic materials, used to install and support cables. Not only can it carry a large number of cables, but its multi-layer design also allows for cable classification and zoning, improving the neatness of cable laying and maintenance efficiency. Multi-layer cable trays are widely used in buildings, industrial facilities, data centers, and other locations, and are an integral part of cable wiring systems. However, existing multi-layer cable trays cannot effectively position the cables within them, causing multiple cables to slip and tangle, resulting in poor stability. Utility Model Content

[0006] Preferably, the surfaces of the worms are meshed with worm wheels, the tops of the two worm wheels are rotatably mounted with second positioning frames, the bottoms of the two second positioning frames are fixedly connected to the top of the bridge body, the bottoms of the two worm wheels are fixedly mounted with second shafts, the surfaces of the two second shafts are rotatably mounted with second sleeves, and the two second sleeves are fixedly connected to the two sides of the bridge body through fixed heads.

[0007] Preferably, a threaded rod is fixedly installed at the bottom of the second shaft rod, and a positioning seat is rotatably installed at the bottom of the two threaded rods. One side of the two positioning seats is fixedly connected to the bridge body, and a threaded sleeve is threadedly connected to the surface of the threaded rod. Support rods are fixedly installed on both sides of the two threaded sleeves.

[0009] When the two worm gears rotate, they drive the two second shafts to rotate along the inside of the two second shaft sleeves. When the two second shafts rotate, they drive the two threaded rods to rotate along the two positioning seats. When the two threaded rods rotate, they both drive the threaded sleeves to move downward. When the threaded sleeves move downward, they both drive the slider to slide along the inside of the slide groove, which increases the stability of the two threaded sleeves when moving. When the two threaded sleeves move downward, the four supporting rods drive the four connecting strips to move downward.
