[0003] the operation of the vehicle. All kinds of parts of new energy vehicles need to be provided with electric energy by the storage battery to operate stably. Therefore, there will be a large number of wire harnesses on the vehicle.

[0004] The wire harness is an essential part of the vehicle. The wire harness is used to connect all electrical appliances, provide power supply, ground wire and signal transmission between electrical components. Therefore, the assembly of the wire harness on the vehicle, especially the fixation of the wire harness, is particularly important. If it is not fixed firmly, the wire harness will be worn, resulting in the failure of the electrical component function. Seriously, it will also cause the danger of vehicle combustion. At present, the wire harness is usually fixed with a protective tube. However, the existing wire harness tubes are all pipes with open ends at both ends. When in use, the wire harness needs to be passed through from one end to the other end, and when overhauling, the wire harness also needs to be pulled out from one end. At the same time, the pipe size cannot be flexibly adjusted according to the thickness of the wire harness, which is more inconvenient to use. Content of the Utility Model

DETAILED DESCRIPTION

[0022] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] As Figure 1 、 Figure 2 and Figure 3 shown, a wear-resistant tube proposed in an embodiment of the present utility model includes a tube body formed by spiral winding of a soft strip 1 and a tube head 2 arranged at the end of the tube body. The first connecting edge 101 integrally provided at one side edge portion of the soft strip 1 is spirally wound and overlapped on the second connecting edge 103 integrally provided at the other side edge portion, which is convenient for spirally winding the soft strip 1 together to form a stable tube body. During use, the two ends of the tube body are cut flat according to actual needs, and then the tube head 2 is installed to form a tube for protecting the automotive wiring harness. The automotive wiring harness is sleeved, and stable and effective protection is provided to ensure the stable use of the automotive wiring harness test piece. Moreover, wear-resistant layers 105 are provided on both sides of the soft strip 1, which is convenient for improving the overall wear resistance of the combined tube body, reducing wear during use, and extending the service life. In addition, the end of the tube body formed by spiral winding of the soft strip 1 is inserted into the tube head 2, and the tube head 2 is used to improve the stability of both ends of the combined tube body to ensure stable use. At the same time, it is also convenient to stably connect the end of the combined tube body to the components at the use position, improving the convenience of use.

[0025] As Figure 1 and Figure 2 shown, in some embodiments, a plugging convex strip 102 is integrally provided on the surface where the first connecting edge 101 and the second connecting edge 103 overlap. The plugging convex strip 102 is plugged into the plugging groove 104 opened at the corresponding position on the second connecting edge 103, which is convenient for stably connecting the first connecting edge 101 and the second connecting edge 103 together during the spiral winding process of the soft strip 1, so that the edge portions of the soft strip 1 are stably connected together to form a stable tube body for stable use. Among them, when needed, adhesive can be applied to the mutually overlapping surfaces of the first connecting edge 101 and the second connecting edge 103 to further enhance the connection stability between the two and ensure stable connection;

[0026] The thicknesses of both the first connecting edge 101 and the second connecting edge 103 are half of that of the soft strip 1, ensuring the flatness at the connection part after the two are overlapped and ensuring stable use.

[0027] As Figure 1 and Figure 3 shown, in some embodiments, a flange plate 202 is fixedly connected to the outer wall of the insertion pipe 201 of the pipe head 2. The insertion pipes 201 on both sides of the flange plate 202 are respectively set as a connection section and a plug-in section. The plug-in section is plugged into the end of the pipe body formed by the spiral winding of the soft strip 1, so as to facilitate the use of the flange plate 202 to form a limiting member on the insertion pipe 201, so that the end of the combined pipe body can be stably connected to the pipe head 2, ensuring stable cooperation between the two when used together. At the same time, the set connection section facilitates the stable connection of the pipe head 2 to other components of the vehicle body at the use position, so as to stably install the end of the combined pipe body and ensure stable use;

[0028] An elastic arc plate 203 is fixedly connected to one side of the plug-in section of the flange plate 202. The other end of the elastic arc plate 203 is bent towards the insertion pipe 201 to form a contact end 204. The elastic arc plates 203 are distributed in an annular array outside the insertion pipe 201. One end of the elastic arc plate 203 where the contact end 204 is located is tilted away from the insertion pipe 201, and one end of the elastic arc plate 203 where the contact end 204 is located is tilted. This facilitates the smooth plugging of the end of the combined pipe body onto the insertion pipe 201, realizing the rapid connection between the combined pipe body and the pipe head 2. At the same time, the elastic arc plates 203 form a clamping component on the outside of the insertion pipe 201 for clamping and fixing the end of the combined pipe, improving the stability of their connection and preventing the end of the combined pipe body from falling off the pipe head 2 during use. The contact end 204 is used to increase the contact surface between the end of the elastic arc plate 203 and the outer wall of the combined pipe body, enhancing the stability of clamping and fixing, and stably and effectively limiting and fixing the end of the combined pipe body;

[0029] A fastening ring 205 is slidably connected to the elastic arc plate 203. An integrally formed buckle 206 is provided on the fastening ring 205. The buckle 206 is arranged in cooperation with the contact end 204 at the end of the elastic arc plate 203. And the width of the buckle 206 is smaller than the width of the deformation groove provided between the elastic arc plates 203. After the end of the combined pipe body is inserted into the insertion pipe 201, the fastening ring 205 is pushed to slide on the elastic arc plate 203 towards the contact end 204, and the elastic arc plate 203 is pushed and resisted during the sliding process, so that the contact end 204 is tightly pressed against the outer wall of the combined pipe body to perform stable and effective clamping and fixing. At the same time, the buckle 206 is buckled on the contact end 204 to prevent the fastening ring 205 from sliding back, and the fastening ring 205 is limited to one end of the contact end 204 of the elastic arc plate 203. When it is necessary to reset the fastening ring 205, only need to rotate the fastening ring 205 on the elastic arc plate 203 to make the buckle 206 move to the position of the deformation groove, and then push the fastening ring 205 to slide back to its original position. Among them, the deformation grooves provided between the elastic arc plates 203 ensure that the elastic arc plates 203 can smoothly deform during the contact process of the fastening ring 205, so that the contact end 204 is tightly pressed against the outer wall of the combined pipe body.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
