Cable support with looseness warning function

Abstract

The invention discloses a cable support with a looseness warning function, which comprises a channel, a plurality of vertical plates are symmetrically arranged on the inner wall of the channel throughfixing bolts, each vertical plate is horizontally and fixedly connected with a placement plate for placing a cable, and a mounting groove is formed in one side, close to the inner wall of the channel, of each vertical plate; a movable plate is elastically connected into each mounting groove through a reset spring, and a plurality of ejector blocks corresponding to the mounting grooves are evenlyand fixedly connected to the inner wall of the channel. According to the invention, when the cable support is deformed or the bolt is loosened, the indication roller can be driven to rotate through the cooperation of the reset spring, the movable plate and the pull wire, so that the position of the indication mark on the indication roller is changed, and an inspector can directly judge whether thesupport is loosened or not through the indication mark on the indication roller; therefore, timely processing can be realized, one-by-one inspection is not needed, and the working efficiency of inspection personnel is further improved.

Description

technical field [0001] The invention relates to the technical field of cable supports, in particular to a cable support with a loosening warning function. Background technique [0002] The cable trench can reduce the occupation of the above-ground space of the cable duct, and can also effectively reduce the impact of people's daily life on the cable. Therefore, many cities use cable trenches to lay cables, and the cables in the cable trench play a role in supporting the cables. For convenience For cable placement and inspection, cable brackets are often installed on one or both sides of the cable trench, and a certain width channel is left between the brackets on both sides or between the bracket and the side wall of the cable trench (one-sided bracket). [0003] In actual use, according to the principle of leverage, the end of the cable bracket far away from the wall of the cable trench is subject to a large force. After a long time of use, the cable bracket is likely to be...

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art that the cable bracket in the traditional cable trench is easily deformed under pressure, the fixing bolts are easy to loosen and fall off, and there is no warning mechanism, which affects the normal use of the cable trench. A kind of cable bracket with loose warning function
