Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, and more specifically to a double high-rib reinforced polyethylene HDPE winding pipe of a flexible inner-lined corrugated pipe. Background Art
[0002] High-density polyethylene (HDPE) is a white powder or granular product; it is non-toxic, odorless, has a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its hardness, tensile strength and creep are better than those of low-density polyethylene; it has good wear resistance, electrical insulation, toughness and cold resistance; it has good chemical stability, is insoluble in any organic solvent at room temperature, and is resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air and low water absorption; it has poor aging resistance and is not as resistant to environmental stress cracking as low-density polyethylene, especially thermal oxidation will cause its performance to deteriorate, so antioxidants and ultraviolet absorbers must be added to the resin to improve this aspect.
[0003] The winding tube, also known as the winding tube (a popular name, the winding tube covers a wider range), the rolled end tape (the professional name of the wiring industry such as Xi'an Jinai Nylon Products Co., Ltd.), is a spiral hose protective sleeve, commonly made of polyethylene, polypropylene, and nylon. It has the function of binding and protecting internal products such as hydraulic hoses, wires, and cables.
[0004] In actual use, the winding tube cannot be too tight but must play a restraining role on the cable and isolate the cable from friction. If necessary, it needs to be fully covered to prevent it from falling off. It can better prevent the cable skin from oxidizing. However, the cable will heat up during use, and ordinary winding tubes will be secondary plastic after compression under warm conditions, causing the cable to be exposed. Utility Model Content

[0007] The present utility model is further configured such that: one side of the clamping strip close to the inner side of the winding tube body is an arc edge, and one side of the clamping strip far from the outer side of the winding tube body is a right-angle edge.
[0008] The present utility model is further configured such that: a deformation layer is provided on the inner side of the winding tube body, and a lining layer is provided on one side of the deformation layer far from the winding tube body.
[0009] The present utility model is further configured such that: a lining slope is provided on one side of the lining layer far from the deformation layer and close to the fastening edge.

[0026] Preferably, two parallel reinforcing ribs 8 are arranged along the axial direction of the winding pipe body 1 to increase its mechanical compressive performance and prevent bending after softening.
[0027] Preferably, in order to better extend its mechanical properties and ensure that the edges are not tight enough between the edges after softening, reinforcing ribs 8 are arranged along the radial direction of the winding pipe body 1 in the buckle groove 10.
