Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. The specific embodiment is as follows:

referring to fig. 2-4, a rotatable cable tray includes a plurality of tray units 1, hinges 2 and adjustable connector assemblies 3 connecting the tray units 1 together, and independent mating covers 4; the bridge unit 1 comprises a cable trough 101 and a separate trough cover 102 covering the cable trough 101; the hinges 2 are arranged on the bottom surfaces of the cable grooves 101 of two adjacent bridge units 1, so that the cable bridge is bent at different angles; the connecting assembly 3 is arranged on the side surface of the cable groove 101 of two adjacent bridge units 1, and plays a role in reinforcing connection and simultaneously does not influence bending of a cable bridge. In order to strengthen the connection of the bridge units 1, a plurality of hinges 2 are arranged between every two bridge units 1; and connecting components 3 are mounted on the two side walls of the cable trough 101. And the rotatable cable bridge can be flatly placed or folded by turning over the hinge, so that the storage and the transportation are facilitated.

In this embodiment, the hinge 2 includes a left half hinge 201 and a right half hinge 202 that can be turned over, and a hinge shaft 203 connecting the left half hinge 201 and the right half hinge 202; the cable bridge bracket arm is combined to be fixed at a required angle, so that the positioning effect is achieved.

In this embodiment, the connection assembly 3 includes a sliding frame 301 and a sliding rod 302, one end of the sliding frame 301 and one end of the sliding rod 302 are respectively and rotatably fixed on the side walls of two adjacent cable troughs 101, and the other end of the sliding rod 302 is clamped in the slide way of the sliding frame 301 through a clamping pulley 303. When the cable bridge is bent, the clamping pulley 303 on the sliding rod 302 slides on the inner sliding way of the sliding frame 301, and simultaneously, the sliding frame 301 and the sliding rod 302 rotate together, so that the bending of the cable bridge is not influenced.
