[0002] A cable tray is a device used to carry and protect cables during the erection of power transmission lines. It consists of brackets, arms, and installation accessories, etc. The types are divided into trough type, tray type, ladder type, grid type, etc. It can be erected independently or laid on various building substrates.

[0003] In Chinese Patent CN202322305182.0, the utility model provides a cable tray. The utility model includes a mounting plate arranged between the two inner side surfaces of a cabinet. A plurality of second wire grooves are arranged along the length direction at the top of the mounting plate. A set of telescopic mechanisms are arranged at both ends of the mounting plate. The telescopic ends of the two sets of telescopic mechanisms are respectively fixedly connected to the tail end positions on the two inner sides of the cabinet. A plurality of groups of length adjustment mechanisms are arranged in an array on the outer side surface of the mounting plate. A U-shaped clamping seat parallel to the mounting plate is also fixedly installed on the outer side surface of the mounting plate. A plurality of first wire grooves are arranged along the length direction on the top surface of the U-shaped clamping seat. The front end of the cable passes through the U-shaped clamping seat, the length adjustment mechanism, and the second wire groove in sequence and then is connected to the port of the switch. Through the arrangement of the telescopic mechanism and the length adjustment mechanism, the distance between the mounting plate and the switch can be increased during wiring, providing sufficient operating space for the plugging and unplugging actions of the cable.

[0004] Although the existing cable trays can solve the problem that the distance between the cable tray and the switch port is fixed and short, making it necessary to bend the cable joint to align with the switch port during wiring, resulting in inconvenient plugging and unplugging actions of the cable joint, the overall cable may be heavier during multi-layer laying, which leads to the need for a stronger support structure and greater load-bearing capacity. Especially when operating in a limited space, it may be more difficult to maintain and adjust.

[0005] Therefore, an adjustable cable tray for multi-layer laying is proposed to solve the above problems. Content of the Utility Model
