Description

Technical Field

[0001] This utility model relates to the field of pipe fitting structure technology, specifically to a polygonal anti-bend water pipe. Background Technology

[0002] Pipe fittings are extremely common in daily life and industrial production. After production, pipe fittings are usually coiled together in a loop before being packaged and sold. Currently, the most common pipe fittings are cylindrical in shape. When coiling or bending, indentations are easily formed at the bends, causing the inside of the pipe fitting to be squeezed and deformed. During use, the inner diameter of the pipe fitting is easily reduced, affecting the flow rate of the liquid inside the pipe fitting. Therefore, this utility model proposes a new type of polygonal anti-bending water pipe. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model proposes a polygonal anti-bend water pipe with a reasonable structural design.

[0004] The technical solution of this utility model is as follows:

[0005] A polygonal anti-bend water pipe includes a water pipe body, the inner hole of the water pipe body has a circular cross-section, and the outer edge of the water pipe body has a regular polygonal cross-section; the outer wall surface of the water pipe body has multiple stripes in the circumferential direction, and the stripes extend along the axial direction of the water pipe body, which can play a strong supporting role and prevent the water pipe from denting when bent.

[0006] Furthermore, the cross-section of the outer edge of the water pipe body is a regular triangular, regular quadrilateral, regular pentagon, regular hexagon, regular heptagon, or regular octagon.

[0007] Furthermore, the cross-section of the outer edge of the water pipe body is preferably a regular hexagon, and six stripes are formed on the circumferential direction of the outer wall surface of the water pipe body.

[0008] Furthermore, the adjacent stripes are planar structures, and the stripes are the intersection lines of adjacent planar structures.

[0009] Furthermore, the main body of the water pipe is formed in one piece using a mold; the mold includes a die and a core mold, the core mold is a conical structure, the die has a conical hole that matches the core mold, and the end face of the die has a hexagonal opening.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1) By changing the traditional cylindrical shape of the water pipe to a multi-deformable structure, a corresponding number of slats are formed on the outside of the water pipe, which can prevent the phenomenon of dents at the bend when the water pipe is coiled or bent.

[0012] 2) By setting up a one-time forming mold, the water pipe can be formed in one step, which greatly improves production efficiency.

[0013] 3) The polygonal structure of the water pipe has a certain resistance to compression, making it easy to transport in bulk. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a polygonal anti-bend water pipe includes a water pipe body 1. In this embodiment, the cross-section of the outer edge 102 of the water pipe body is a regular hexagon, and the cross-section of the inner hole 101 is circular.

[0021] The outer edge 102 of the water pipe body has a regular hexagonal cross-section. Six stripes are formed on the outer surface of the water pipe body 1, and the stripes extend along the axial direction of the water pipe body. The stripes are planar structures between adjacent stripes, and the stripes are the intersection lines of adjacent planar structures.

[0022] The purpose of the slats is to provide strong support and prevent dents from forming when the water pipe is bent. Figure 1 A cross-sectional view of a water pipe body 1 in a coiled state is shown. It can be seen from the cross-sectional view that the distance from the stripe to the inner wall is greater than the distance from the plane between the stripes to the inner wall. Therefore, the stripe is thicker and has better resistance to compression.

[0023] like Figure 2 As shown, the main body 1 of the water pipe is formed in one piece using a mold; the mold includes an orifice mold 3 and a core mold 2;

[0024] like Figure 4 As shown, core mold 2 has a conical structure;

[0025] like Figure 3As shown, the die 3 has a conical hole 301 that matches the core die, the core die 2 is installed in the conical hole 301, and there is a certain extrusion gap between the outer wall of the core die 2 and the inner wall of the conical hole 301.

[0026] The die 3 has a hexagonal orifice 302 on its end face. The end face of the core die 2 is flush with the end face of the die 3. The extruder discharges material from the extrusion gap through the end face of the die and core die. After cooling, it forms a polygonal anti-bend water pipe of this utility model.

[0027] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
