Technical Field

[0001] The utility model relates to the technical field of charging pile electric wires, in particular to an electric wire sheath for a charging pile. Background Art

[0002] There is a Chinese utility model patent with application number CN201720150684.2 and the name of "A protective sleeve for electric wires and cables", which discloses a protective sleeve for electric wires and cables, including a cable protective sleeve, the cross-section of the cable protective sleeve is hexagonal, a cable accommodating cavity is provided in the cable protective sleeve, and barbs are provided on the side walls of the cable accommodating cavity, wherein the cable protective sleeve is also provided with an opening connected to the cable accommodating cavity, the opening is arranged parallel to the two corresponding sets of side walls in the cable protective sleeve, and one end of the opening is located at one of the top corners in the cable protective sleeve, and the outer surface of the cable protective sleeve is also uniformly provided with stripes. The utility model can effectively protect the safety of the cable and prevent the cable from being damaged. However, the stripes of the protective sleeve are arranged on the outer wall, and the inner wall protection structure is relatively simple. The cable protective sleeve is made of rubber, and the rubber is prone to aging after a period of use, which affects the protection effect. Therefore, the structure of the protective sleeve needs to be further improved. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a wire sheath for a charging pile with a long service life and good protection effect in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: the wire sheath for the charging pile includes a bendable sheath, which is a tubular structure with openings at both ends, and is characterized in that grid-like protrusions are distributed on the inner wall of the sheath, and the sheath and the protrusions are an integral structure made of TPU material.

[0005] As an improvement, the arrangement direction of the grid grooves formed by the protrusions may preferably be parallel to the axial direction of the sleeve body.

[0006] As a further improvement, the top-view projection of the grid grooves formed by the protrusions may preferably be square.

[0007] As a further improvement, the bottom end of the protrusion may preferably be a smooth curved surface.

[0008] As an improvement, anti-skid particles may be preferably distributed on the outer surface of the sleeve.

[0009] As a further improvement, the anti-slip particles and the sleeve body may preferably be an integral structure made of TPU material.

[0010] As a further improvement, the anti-skid particles may preferably be conical, and the top surface of the anti-skid particles is a circular arc top.

[0011] As a further improvement, the height of the anti-slip particles may preferably be 0.04 to 0.13 of the thickness of the casing.

[0012] As an improvement, the thickness of the protrusion may preferably be 0.25 to 0.4 of the thickness of the sleeve body.

[0013] As an improvement, the radial cross section of the sleeve body may preferably be circular.

[0014] Compared with the prior art, the advantages of the utility model are: grid-like protrusions are distributed on the inner wall of the sleeve, the protrusions can increase the strength of the sleeve, and at the same time the sleeve can be better plugged into the wire, and the application effect is good; the sleeve and the protrusions are an integral structure made of TPU material, with high molding efficiency, TPU material is pressure-resistant and anti-aging, and effectively extends the service life of the wire sheath.
