Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be considered as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model relates to a schematic diagram of environment-friendly PVC drain pipe embodiment, fig. 2 is the utility model relates to a schematic diagram of first through-hole embodiment in the environment-friendly PVC drain pipe, as shown in the figure, an environment-friendly PVC drain pipe, including the body, the body is integrated into one piece to establish the outer tube 2 in the 1 outside of inner tube including inner tube 1 and cover, inner tube 1 is circular with the outside of outer tube 2.

First through holes 3 are uniformly distributed in the pipe wall of the inner pipe 1, second through holes 4 are distributed in the pipe wall of the outer pipe 2, and the first through holes 3 and the second through holes 4 are both arranged in a spiral mode. First through-hole 3 is regular hexagon with second through-hole 4, and the high strength of inner tube 1, outer tube 2 can be guaranteed in the structure setting of first through-hole 3 and second through-hole 4. Be regular triangle distribution between first through-hole 3 and the adjacent second through-hole 4, effectively improve the bearing strength of inner tube 1 and outer tube 2, prevent that first through-hole 3, second through-hole 4 intercommunication from producing the condition that intensity weakens.

The inner wall of the inner tube 1 is provided with ribs 5 which are spirally distributed, and the number of the ribs 5 is 8 and is evenly distributed on the inner wall of the inner tube 1. The spiral directions of the convex ribs 5, the first through holes 3 and the second through holes 4 are the same, water flows along the direction of the convex ribs 5, great noise is generated, the suction area can be increased in the rotating direction of the first through holes 3 and the second through holes 4, and therefore noise generated by the water flows can be better absorbed. In addition, the convex ribs 5 are positioned between the adjacent first through holes 3, so that the bearing strength of the inner pipe 1 can be effectively improved. The most advanced inboard of bead 5 extends, and the lateral surface and the medial surface of bead 5 are smooth curved surface structure for rivers flow along the direction of rotation of bead 5, prevent the high strength noise that rivers direct current brought.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the present invention, and these modifications should also be construed as the protection scope of the present invention.
