Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a portable extension cable. Background Art

[0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating protective layer. It is laid underground, in the air, etc. Cables generally consist of three parts: conductor, insulation layer, and protective layer. There are usually two types of cables: power cables and control cables. Power cables are mainly used for the transmission and distribution of electric energy; control cables are mainly used for measurement, protection, control and other lines. The cables have the characteristics of internal power supply and external insulation.

[0003] When currently used for transportation, cables are usually rolled into a loop. However, after the cables are looped, the connections between the coiled cables are not stable, which can easily lead to tangling of the cables when carried. Therefore, we propose a portable extension cable to solve this problem. Utility Model Content

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3In the utility model, a portable extension cable includes a cable body 1. The outer surface of the cable body 1 is fixedly connected to a support plate 2. The left side of the support plate 2 is fixedly connected to a group of clamping rings 3. Each clamping ring 3 is clamped on the outer surface of the cable body 1. The clamping ring 3 can be used to form a preliminary positioning of the cable body 1, which is convenient for the subsequent stable arrangement of the cable.

[0020] A splint 4 is provided on the left side of the cable body 1, and an anti-wear pad 14 is fixedly connected to the right side of the splint 4. The right side of the anti-wear pad 14 is in contact with the outer surface of the cable body 1. The anti-wear pad 14 can further protect the cable body 1 to avoid wear and leakage of the cable body 1, thereby improving safety.

[0021] The right side of the support plate 2 is provided with two connecting grooves 11, and an L-shaped plate 5 is clamped inside each connecting groove 11. The right sides of the two L-shaped plates 5 are fixedly connected with a pull rod 6, and the pull rod 6 can be used to connect the L-shaped plates 5, so that the two L-shaped plates 5 can be pulled at the same time. The right side of each L-shaped plate 5 is provided with a sliding hole 8, and the inner wall of each sliding hole 8 is slidably connected with a sliding rod 7.
