Light-emitting cable convenient to construct and maintain

Abstract

The invention discloses a light-emitting cable convenient to construct and maintain. The light-emitting cable comprises a protection box, a plurality of connection devices are arranged on the periphery of the protection box, a containing cavity is formed in the protection box, a sealing cap is hinged to the side wall of one end of the containing cavity, the containing cavity is internally and rotationally connected with a rotary wheel, a crank is fixed to one side of the rotary wheel, fixed pipes are fixed to the two ends of the protection box, the middles of the fixed pipes are communicated with each other, one end of each fixed pipe is communicated with the containing cavity, the light-emitting cable is arranged on one fixed pipe in a penetrating mode, and one end of the light-emitting cable is wound on a fixed wheel and penetrates through the other fixed pipe. By combining the rotary wheel, the fixed pipes and the crank, stable collection and fixing of the cable are achieved; by combining T-type sliders, a T-type sliding groove and first connection blocks, the whole protection box is adjusted, cable arrangement time is reduced, the cable is protected, and the cable is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a light emitting optical cable which is convenient for construction and maintenance. Background technique [0002] Usually a step-type polymer optical fiber, the refractive index of the core material is higher than that of the skin material. The core material is mostly transparent polymer or transparent organic matter. Since the whole body light-emitting optical fiber is mostly used in lighting and decoration, in order to ensure its excellent mechanical properties and aging resistance, the leather is usually made of fluoroplastics, such as polytetrafluoroethylene. In order to prolong the service life of the whole-body luminescent optical fiber, a layer of transparent material with good anti-aging, anti-ultraviolet and weather resistance, such as transparent polyvinyl chloride, is usually coated on the outside of the whole-body luminescent optical fiber. In the process, i...

Problems solved by technology

In order to prolong the service life of the whole-body luminescent optical fiber, a layer of transparent material with good anti-aging, anti-ultraviolet and weather resistance, such as transparent polyvinyl chloride, is usually coated on the outside of the whole-body luminescent optical fiber. In the process, it is often a mess because the optical cable is too long or not arranged well, and it will take a lot of time to arrange it again, which is very inconvenient. Therefore, we propose a light-emitting optical cable that is convenient for construction and maintenance to solve the above problems
