Abstract

The utility model discloses a plastic pipe, which comprises a circular pipe. Wherein, the circular pipe comprises an inner wall and an outer wall, the inner wall and the outer wall are tightly integrated, and the inner wall is a smooth circular pipe; The plastic pipe is characterized in that the outer wall is corrugated, the bulge of the corrugation of the outer wall is hollow-rectangle structured, and the concave of the corrugation of the out wall is the inner wall. The plastic pipe is a double-wall corrugated pipe, which has the function of the smooth circular pipe and the single wall corrugated pipe; the smooth and circular inner wall makes the water flow more unhindered, and the pipeline is unobstructed by avoiding the coemption and stagnation of the waste; the corrugated outer wall with the structure of hollow rectangle has the advantages of raw material saving, cost reducing, weight lightening, and better resistance of pressure and flexibility.

Description

A kind of plastic tube

Technical field

The utility model relates to a kind of plastic tube.

Background technique

Used plastic tube has two big classes at present, and the first kind is level and smooth pipe, and this plastic tube volume is heavy, and manufacture process Central Plains material consumption is very big, cost height, price height; Second class is a single-wall corrugated pipe, though this plastic tube is saved raw material, crushing resistance is relatively poor, and pliability is also relatively poor.

Summary of the invention

The waved plastic pipe that the utility model aims to provide and a kind ofly saves material, cost is low, price is low, compression resistance is good, pliability is good.

For achieving the above object, the utility model is taked following structure: it comprises pipe, pipe has inwall, outer wall, inwall and outer wall closely fuse, the inwall of pipe is level and smooth, it is characterized in that outer wall is undulatory, and the convex portion of the ripple of outer wall is a rectangle, the internal structure of rectangle is a hollow structure for the section of radially crossing axial plane along pipe, and the sunk part of the ripple of outer wall is exactly an inwall.

The utility model is a double-wall corrugated pipe, the function of level and smooth pipe and single-wall corrugated pipe of holding concurrently, and level and smooth circular inner wall makes current more smooth and easy, avoids waste to hoard stagnation, and pipeline is unblocked; The ripple outer wall of hollow, rectangular structure has not only been saved raw material, has reduced cost, and has alleviated weight, has better crushing resistance and better pliability.

Embodiment

Embodiment: Fig. 1, Fig. 2, shown in Figure 3, comprise pipe 0, pipe 0 has inwall 1, outer wall 2, inwall 1 closely links into an integrated entity with outer wall 2, inwall 1 is level and smooth pipe, and outer wall 2 is undulatory, and the convex portion 4 of the ripple of outer wall 2 is rectangles, the internal structure of rectangle is a hollow structure for the section of radially crossing axial plane along pipe 0, and the sunk part 3 of the ripple of outer wall 2 is exactly an inwall 1.

Claims

1, a kind of plastic tube, it comprises pipe, pipe has inner and outer wall, inwall and outer wall closely link into an integrated entity, and the inwall of pipe is level and smooth, it is characterized in that outer wall is undulatory, the convex portion of the ripple of outer wall is a rectangle, and the sunk part of the ripple of outer wall is exactly an inwall.

2, plastic tube as claimed in claim 1, the inside that it is characterized in that the rectangle of circular tube external wall projection are that the section of radially crossing axial plane along pipe is the hollow, rectangular structure.
