Background

In the electrical and automation system wiring engineering construction of industrial and civil buildings, cables need to be arranged in each section of pipeline in a penetrating mode, and for turning positions, 90-degree elbow joints are usually adopted to achieve connection between two sections of straight pipes. When the cable is threaded, the cable is often clamped when the cable is threaded through a 90-degree elbow joint, so that the difficulty of site construction is increased. Especially when the cable is thicker and the caliber of the 90-degree elbow joint is smaller, the clamping stagnation phenomenon is more frequent. Constructors can pass the cable through the 90-degree elbow joint by continuously bending the cable, so that the construction efficiency is low. In addition, the cable rubs at the bent pipe for many times, so that the electric wire insulating protective layer is easily damaged, the safety performance of the cable is reduced, and the maintenance operation of later-stage line changing and the like on the circuit is not facilitated.

In addition, still there is a cable threading structure to adopt the whole reel form plastic tubing of purchase, through expanding the back, encloses into circular arc transition structure's threading tubular construction along the overall arrangement of construction site, and the rethread card is arranged fixedly, and the drawback of this kind of structure is, and the threading pipe self that encloses into circular arc transition structure has great stress, when fixed insecure with the card row, can break away from in the card row, becomes straight tubulose, causes the threading of intraductal overall arrangement to take place the rupture, and there is the potential safety hazard in this kind of structure. Secondly, the whole coiled plastic pipe occupies a large space and is not beneficial to construction transportation and storage of a construction site.
