Description

Technical Field

[0001] The utility model relates to the technical field of wire trough brackets, in particular to a wire trough bracket structure. Background Art

[0002] The main function of the cable bracket is to support and fix the cables. The cable brackets on the market are usually split and composed of a large number of independent brackets. The on-site installation time is long, and multiple cable brackets are generally only equidistantly set at predetermined points of the cables and do not carry all the cables. Therefore, after a long period of use, the cable segment between two adjacent cable brackets is not carried and is prone to falling due to gravity, causing the cables to be out of a straight line, affecting the stability of their overall function. In addition, the cable sheath is not protected and is prone to wear, posing a safety hazard. Therefore, a cable trough bracket structure is urgently needed to solve the above problems.
