A kind of polyurethane resin cable tray and its manufacturing method

Abstract

The invention discloses a polyurethane resin cable tray and a manufacturing method thereof, relates to the technical field of cable trays, and solves the problems of cable arrangement and fixing methods. A polyurethane resin cable tray and its manufacturing method, comprising a shell structure, a dust-proof structure is installed on the upper end surface of the shell structure, an adapter is installed at one end of the shell structure, and the two sides of the dust-proof structure are arranged There is a dust-proof net, fixed grooves are arranged on both sides of the inner wall of the dust-proof structure, and a fixed structure is installed on one side of the upper end surface of the dust-proof structure. , partition, support spring and limit plate, the inner side of the housing is provided with an inner groove, the upper end surface of the inner groove is equipped with a classification plate, the upper end surface of the classification plate is provided with two partitions, the inner groove Connecting pins are installed on both sides of the inner wall. The invention enables the device to realize ventilation and heat dissipation, tidy internal wiring, and a structure that is convenient for fixing.

Description

technical field [0001] The invention relates to the technical field of cable trays, in particular to a polyurethane resin cable tray and a manufacturing method thereof. Background technique [0002] The cable tray is divided into trough type, tray type, ladder frame type, grid type and other structures. It is composed of brackets, brackets and installation accessories. The bridge frame in the building can be erected independently or laid on various buildings (structures). And the bracket of the pipe gallery should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed on the bridge outside the building. [0003] However, the existing cable trays are cumbersome to install and fix, lack ventilation and heat dissipation structures, and the wiring of the internal cables is messy and lacks a wiring structure; therefore, it does not meet the existing needs, and we propo...
