For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0021] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, a glue-free hot air welded corrugated pipe structure is described, wherein the structure of the glue-free hot air welded corrugated pipe structure is as follows: Figure 1 As shown, it includes a tube body 10, which has a first opening 101, a cavity 102, and a second opening 103. Both the first opening 101 and the second opening 103 are connected to the cavity 102, and both are also connected to the outside. The body is made of ribs drawn from EVA+PE material. After the inclined surface of one side of the ribs is heated by a hot air gun, the inclined surface is formed and welded by an upward threading method to form a shape as shown. Figure 2 The structure shown.

[0022] Among them, such as Figure 2The cross-sectional structure of the tube body 10 is such that one side of the tube body 10 is formed by bonding together a plurality of protrusions 11 arranged in parallel. Each of the protrusions 11 includes a first connecting part 111, a second connecting part 113 and a protrusion 112. The first connecting part 111 and the second connecting part 113 are located on both sides of the protrusion 112 and are connected to the protrusion 112.

[0023] It is worth mentioning that the first connecting portion 111 has a first inclined surface 1111 and a first plane 1112. The first inclined surface 1111 is located on the upper side of the first plane 1112 and is spaced apart by a predetermined distance. The second connecting portion 113 has a second inclined surface 1131 and a second plane 1132. The second inclined surface 1131 is located on the lower side of the second plane 1132 and is spaced apart by a predetermined distance.

[0024] Furthermore, the first inclined surface 1111 contacts and is bonded to the second inclined surface 1131, with the first inclined surface 1111 located below the second inclined surface 1131.

[0025] Furthermore, the protrusion 112 has an outwardly convex structure, and multiple protrusions 112 are spaced apart to form the outer surface of the tube body 10. Additionally, the inner side of the protrusion 112 has a groove 11201 with an opening, the opening of which communicates with the cavity 102. Those skilled in the art should understand that when the aforementioned ribs are threaded upwards, the protrusion 112 becomes an annular protrusion 112 and is tilted at a predetermined angle, while the groove 11201 becomes an annular groove 11201 and communicates with the cavity 102.

[0026] It should be noted that the length of the first connecting part 111 is greater than the length of the second connecting part 113, and the end of the first connecting part 111 that is away from the protrusion 112 is an arc surface.

[0027] In addition, the end of the second connecting portion 113 that is away from the protrusion 112 is also spaced at a predetermined distance from the surface of the adjacent protrusion 112, so that the end of the second connecting portion 113 will not be squeezed on the side wall of the protrusion 112 during the winding of the reinforcing rib.

[0028] In summary, the glue-free hot air welded corrugated pipe structure described in the embodiments of this application has been clarified, which provides advantages such as simple structure and no glue required for the glue-free hot air welded corrugated pipe structure.

[0029] It is worth mentioning that, in the embodiments of this application, the glue-free hot air welded corrugated pipe structure is simple, does not involve complex manufacturing processes or expensive materials, and has high economic efficiency.
