Abstract

The invention belongs to the technical field of electrical equipment accessories, and relates to a cable bridge closed based on gravity extrusion. The cable bridge comprises a bottom frame, a fixed plate, wire slot frames, a movable frame, a tension spring, a sealing element, a sealing sheet, sliding rods and a pull ring, According to the cable bridge of the invention, a cable passes through the gap between the wire slot frames at two sides and is placed on the movable frame; under the gravity effect of the cable, the movable frame moves downwards, so that the sliding rods in the movable frame slide in sliding grooves, the sliding rods at two sides get close to each other, and the wire slot frames at two sides rotate inwards; and the wire slot frames on the two sides are clamped, so that a closed space is formed, the cable is wrapped, and corrosion to the cable is reduced; in the laying process, only the cable needs to be laid on the movable frame, and automatic closing of the cable bridge can be realized under the gravity action of the cable, so that steps in the cable erecting process are reduced, and the cable laying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment accessories, and in particular relates to a gravity extrusion-closed cable tray. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or laid on various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized If the bridge frame installed in the open air outside the building is near the sea or in a corrosion area, the material must have the physical characteristics of anti-corrosion, moisture resistance, good adhesion, and high impact resistance; in engineering design, the layout of the bridge frame should be According ...
