Shielded weak power cable bridge stand

Abstract

The invention discloses a shielded weak power cable bridge stand and relates to the technical field of a cable bridge stand. The shielded weak power cable bridge stand includes a U-shaped substrate, acover plate and a support frame, wherein a fixed block is fixedly connected with a top portion of a left side of the U-shaped substrate, a rear surface of the fixed block is rotatably connected witha left side of a bottom portion of the cover plate by a connecting rod, and a first sliding rail is fixedly connected with a bottom portion of an inner wall of the U-shaped substrate. The shielded weak electric cable bridge stand is advantaged in that the U-shaped substrate and a shielding layer disposed in the cover plate can prevent a weak electric cable from being interfered by an external magnetic field, smooth and normal operation is achieved, reliability of the cable bridge stand is improved, a movable frame can separate the space inside the U-shaped substrate, cables are classified andplaced and are not easy to be entangled, workers are convenient to distinguish and find, a baffle is pulled outwards to disengage a limiting rod from an arc groove, the position of the support frame can be moved, and thereby the purpose of adjusting the height of a support plate is achieved, a space utilization rate is improved, and practicality is improved.

Description

technical field [0001] The invention relates to the technical field of cable trays, in particular to a shielded weak current cable tray. Background technique [0002] A cable refers to a wire that is made of one or more mutually insulated conductors and an outer insulating layer to transmit power or information from one place to another, or is composed of several or several groups of wires (each group is at least two wires) ) twisted cable similar to a rope, each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The cable has the characteristics of internal energization and external insulation. Cable bridges are often used in erection. Cable bridges are divided into trough type, tray type, ladder type, grid type and other structures. They are composed of brackets, brackets and installation accessories. On the supports of various buildings (structures) and pipe c...
