All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the embodiments of the present invention, it should be further noted that the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, unless explicitly stated or limited otherwise; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases by those skilled in the art; the drawings in the embodiments are used for clearly and completely describing the technical scheme in the embodiments of the utility model, and obviously, the described embodiments are a part of the embodiments of the utility model, but not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

In this embodiment, as shown in fig. 1, fig. 2 and fig. 5, a three-wall reinforced PP skeleton winding pipe is specifically provided, which aims to improve the overall strength of the composite hollow winding pipe and improve the chemical and corrosion resistance thereof, thereby prolonging the service life of the hollow winding pipe, by optimizing the structure of the composite hollow winding pipe.

In practical application, the composite hollow winding pipe mainly comprises: the unit pipe wall, by the unit pipe wall is around the winding pipe body that same helix formed through the winding, and the main part of compound cavity winding pipe is regarded as to winding pipe body, the inside of unit pipe wall is equipped with integrated into one piece and is the bellows of cavity form, and after twining by the unit pipe wall, it is corresponding, then the bellows also can be followed same helix and twined and arrange to this forms a compound cavity winding pipe.
