Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a modular cable tray that can be quickly disassembled and assembled. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] Existing cable trays, due to the large number and weight of cables they carry, require more bolts for fixing in order to meet higher load requirements. This results in slow assembly and disassembly of the cable trays, affecting installation and disassembly efficiency.
