Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-8, the overlapped tighter plastic pipe comprises a plastic pipe body, and is characterized in that: the plastic pipe body comprises a first section 1, a second section 2 and a third section 3 from front to back, wherein the outer diameter of the first section is gradually increased from front to back; the outer diameter of the second section is constant from front to back; the third section comprises two parts, namely a third front section 31 and a third rear section 32, wherein the outer diameter of the third front section is gradually increased from front to back, and the outer diameter of the third rear section is constant from front to back; the outer diameter of the rear end 4 of the first section is less than or equal to the outer diameter of the second section; the interior of the plastic tube body is the lumen 5 which is divided into a first lumen 51 of constant diameter and a second lumen 52 of the same shape as the exterior of the front portion 6 of the plastic tube body from front to back.
The using method comprises the following steps: the utility model discloses a plastic tubing uses when using is a plurality of front and back overlap joints, because the shape of second lumen is the same with the front portion of plastic tubing body, and the shape that here can mean the second lumen is the same with the shape of first section, also can be that the shape of second lumen is the same with the shape of first section plus partial second section. When the plastic pipe is used, the outer side face of the first section of the next plastic pipe is coated with the adhesive glue and then is screwed into the second pipe cavity of the previous plastic pipe, so that the multiple plastic pipes are overlapped front and back, the shape of the second pipe cavity is the same as that of the front part of the plastic pipe body, the next plastic pipe and the previous plastic pipe can be completely matched, and the diameter of the first pipe cavity is constant, so that the pipe cavity of the plastic pipe is constant in diameter and free of steps, and liquid flow cannot be blocked.
