Description

Technical Field

[0001] The utility model belongs to the technical field of protective pipes, and in particular relates to a wear-resistant enhanced HDPE winding pipe. Background Art

[0002] The winding tube is a spiral hose protective sleeve, usually made of polyethylene, polypropylene, and nylon. It has the function of binding and protecting internal products such as hydraulic hoses, wires, and cables, that is, it enhances the wear resistance, anti-static and UV resistance of internal products such as hydraulic hoses, wires, and cables, and plays a role in protecting internal products such as hydraulic hoses in various harsh environments. The winding tube is spiral-shaped and has good elasticity and tensile force, which can play a good binding role for internal products such as hydraulic hoses, wires, and cables. However, the existing winding tubes are mostly used to position the ends with other fasteners, or to position them by hand, which is very cumbersome. Sometimes, when the cable is thick, one person cannot operate it. Therefore, it is very important to obtain a wear-resistant enhanced HDPE winding tube that overcomes the above defects.

[0026] In order to enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, and the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of implementation of the present invention.

[0028] A spiral protection body 1;

[0029] At least one end of the protection body 1 is provided with a positioning component;

[0030] The protection body 1 includes an extension arm 204 disposed on at least one side, and at least a portion of the extension arm 204 overlaps after winding;

[0031] The positioning assembly includes a positioning protrusion 201 provided at an end corner of a first surface of the protection body 1 and a plurality of positioning grooves 202 provided on a second surface of the protection body 1, each of the positioning grooves 202 cooperates with the positioning protrusion 201;

[0032] The inner side wall of the protection body 1 is provided with a filling groove 203 which is parallel to the symmetry axis of the protection body 1 stretched into a plane.

[0033] Through the above technical solution, the utility model can adapt to cables 3 with a wider range of diameters through the cooperation of a positioning protrusion 201 and a plurality of positioning grooves 202, and can also adjust the overlapping range of the extension wall.

[0034] As a preferred embodiment of the above, the spiral protection body 1 is made of HDPE material.

[0035] Through the above technical solution, HDPE is a high-density polyethylene with an operating temperature of up to 100°C; its hardness, tensile strength and creep properties are better than those of low-density polyethylene; and its wear resistance, electrical insulation, toughness and cold resistance are better.

[0036] As a preferred embodiment of the above, the filling groove 203 is trapezoidal, and the length of the bottom of the filling groove 203 is greater than the length of the opening of the filling groove 203; or the filling groove 203 is greater than one-half of an ellipse or a circle.

[0037] Through the above technical solution, the filling groove 203 can be filled with plastic melt to further fix the cable 3 inside.
