Description

TECHNICAL FIELD

[0001] The utility model relates to a cable product, especially a cable capable of emitting warning light. BACKGROUND

[0002] When carrying out outdoor public area construction work, in order to prevent personnel from entering the construction area and causing safety hazards, a warning device needs to be set up around the construction area. This warning device is usually composed of a warning tape that encloses the construction area and warning lights that are set up at intervals. A two-core twisted pair wire (also known as a lamp head wire or a flower wire) that is twisted from two polyvinyl chloride insulated soft wires is used to connect multiple warning lights. Since the two-core twisted pair wire in the prior art does not have light-emitting capability, in low-visibility environments such as at night or in thick fog, haze, dust, and flying sand, the naked eye can only see the warning light and cannot see the warning tape enclosure or the wire connecting the warning lights, which poses a safety hazard of personnel bumping into the warning tape or the wire. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a safety warning cable that can not only connect and power warning lights but also emit a strip-shaped warning light to prevent personnel from bumping into the warning tape or the wire connecting the warning lights and can conveniently adjust the color of the warning light according to environmental needs, has the advantages of simple structure and convenient use.

[0004] The technical solution adopted to solve the technical problem is a safety warning cable, which comprises two polyvinyl chloride insulated soft wires of the same specification. The safety warning cable further comprises a light-emitting cable, which is composed of a red electroluminescent wire that emits red light and a yellow electroluminescent wire that emits yellow light. The safety warning cable is composed of the light-emitting cable and the two polyvinyl chloride insulated soft wires.

[0005] As a further improvement of the utility model, the light-emitting cable and the polyvinyl chloride insulated soft wires are wrapped in a soft transparent plastic sheath.

[0006] As a further improvement of the utility model, the outer diameter of the light-emitting cable is the same as the diameter of the polyvinyl chloride insulated soft wire.

[0007] As a further improvement of the utility model, the red electroluminescent wire and the yellow electroluminescent wire have the same outer diameter.

[0008] As a further improvement of the utility model, the red electroluminescent wire and the yellow electroluminescent wire are respectively composed of an electroluminescent wire core and a red fluorescent plastic sleeve and a yellow fluorescent plastic sleeve that are wrapped around the electroluminescent wire core.

[0009] As a further improved scheme of the present application, the outer surface of the soft transparent plastic sheath is a frosted surface.

[0010] Beneficial effects: the safety warning cable of the present application, due to the technical feature that the safety warning cable is composed of one light-emitting cable and two PVC insulated soft wires, can emit strip-shaped warning light according to the need while connecting the warning light and supplying power to the warning light, preventing the danger caused by the collision of personnel with the warning tape or the electric wire in the night or other low-visibility environment. Due to the technical feature that the light-emitting cable is composed of one red electroluminescent wire emitting red light and one yellow electroluminescent wire emitting yellow light, the red electroluminescent wire and the yellow electroluminescent wire can emit light alone or simultaneously according to the need, and the brightness of each of the red electroluminescent wire and the yellow electroluminescent wire can be adjusted according to the environmental characteristics when the two wires emit light in combination, so that the warning light with better penetration and more attention can be combined in the current environment. Due to the technical feature that the safety warning cable further comprises a soft transparent plastic sheath in which the light-emitting cable and the PVC insulated soft wire are bundled together, the surface of the safety warning cable is smooth and columnar by setting the soft transparent plastic sheath, which can overcome the disadvantage of the poor stability of the bundled structure caused by the bundling of the red electroluminescent wire and the yellow electroluminescent wire and the two PVC insulated soft wires, and can prevent the mud or other impurities from directly adhering to the gap of the bundled light-emitting cable, which is difficult to clean and blocks the warning light. Due to the technical feature that the outer diameter of the light-emitting cable is the same as the diameter of the PVC insulated soft wire, the disadvantage of the unstable bundled structure caused by the diameter difference between the electroluminescent wire and the PVC insulated soft wire is further overcome. Due to the technical feature that the outer diameters of the red electroluminescent wire and the yellow electroluminescent wire are the same, the red electroluminescent wire and the yellow electroluminescent wire are easier to bundle, and the stretching and tightness of the two electroluminescent wires are consistent when the two wires are bundled with the PVC insulated soft wire. Due to the technical feature that the red electroluminescent wire and the yellow electroluminescent wire are respectively composed of the electroluminescent wire core and the red fluorescent plastic sleeve and the yellow fluorescent plastic sleeve covering the electroluminescent wire core, the softness and toughness of the red electroluminescent wire and the yellow electroluminescent wire are better, and the two wires are easier to bundle. BRIEF DESCRIPTION OF DRAWINGS

[0011] The safety warning cable of the present application will be further described in detail below with reference to the accompanying drawings.

[0012] Figure 1 is a schematic diagram of the safety warning cable of the present application. DETAILED DESCRIPTION

[0013] As Figure 1As shown, the safety warning cable is composed of one light-emitting cable and two polyvinyl chloride insulated flexible wires 2 of the same specification, the light-emitting cable is composed of a red electroluminescent wire 3 emitting red light and a yellow electroluminescent wire 4 emitting yellow light.

[0014] Preferably, the outer diameter of the light-emitting cable is the same as the diameter of the polyvinyl chloride insulated flexible wire, and the outer diameters of the red electroluminescent wire and the yellow electroluminescent wire are the same. The red electroluminescent wire is composed of an electroluminescent wire core 32 and a red fluorescent plastic sleeve 31 covering the outside of the electroluminescent wire core, and the yellow electroluminescent wire is composed of an electroluminescent wire core 42 and a yellow fluorescent plastic sleeve 41 covering the outside of the electroluminescent wire core.

[0015] Preferably, a soft transparent plastic sheath 1 is sleeved or extruded on the light-emitting cable and the polyvinyl chloride insulated flexible wire after being twisted together.

[0016] Preferably, the outer surface of the soft transparent plastic sheath is a frosted surface. The soft transparent plastic sheath with a frosted surface makes the light emitted by the light-emitting cable more soft after scattering through the frosted surface, and the visible angle is larger and more eye-catching.

[0017] The safety warning cable of the utility model needs to use two special AC frequency modulation power supplies to supply power to the red electroluminescent wire and the yellow electroluminescent wire respectively, and the brightness of the red electroluminescent wire and the yellow electroluminescent wire is adjusted through the AC frequency modulation power supply, so as to combine warning lights of different colors. When it is a fine weather night, the red electroluminescent wire can work alone to emit red warning light, and when it is a thick fog weather, the red electroluminescent wire and the yellow electroluminescent wire can work together to emit orange light with better penetration effect in thick fog, and the brightness of the red electroluminescent wire and the yellow electroluminescent wire can also be adjusted alone according to the background of the construction site to combine more eye-catching warning light, so as to emit strip-shaped warning light while connecting and powering the warning light, and the construction area is surrounded by the warning light to prevent personnel from colliding or entering the construction area and causing safety hazards.
