- FIGS. 3 and 4 are cross-sectional views of suction pipes in which the material composition of the large-diameter pipe and the small-diameter pipe is different.
- Figure 5 is a cross-sectional view of a suction pipe in which the small-diameter pipe is stabilized based on the structure and material composition of the large-diameter pipe and the small-diameter pipe.
- Reference numeral 1 denotes a large-diameter pipe having a convex portion 3 protruding inward near an end on the side where the end of the small-diameter pipe remains when used.
- Reference numeral 2 denotes a small-diameter pipe, which has a flange 4 protruding outward near an end on the side that remains in the large-diameter pipe when used similarly to a conventional two-stage pipe.
- the plunger 4 is inserted into the large-diameter pipe 1 so as to be stretchable so as to be in close contact with the inner surface of the large-diameter pipe 1.
- the flange 4 prevents air from being sucked or leaked.
- the flange 4 is provided near the end of the small-diameter pipe 2 as shown in the figure, because it is preferable to increase the length of the entire pipe.
- the pipe of this embodiment also has the convex portion 3 on the inner surface of the large-diameter pipe 1, the small-diameter pipe 2 is pulled out to increase the overall length of the pipe.
- the flange 4 of the small-diameter pipe 2 hits the convex portion 3 and cannot be stretched any further, so that the pipe 4 does not come off. That is, the projection 3 of the large-diameter pipe 1 also functions as a stopper.
- the small-diameter pipe 2 is distorted by the projection 3. Therefore, the flanges 4 cling to the inner surface of the large-diameter pipe 1 in a stable and intimate state. In addition, stable sliding operation can be performed.
- the large-diameter pipe 1 may be provided with a single convex portion 3, but a more stable sliding can be provided by providing a plurality of convex portions along the circumferential direction or an annular convex portion. It becomes possible.
- FIG. 2 shows a large-diameter pipe tip 5 having a smaller diameter than other parts as shown in FIG.
- the small-diameter distal end portion 5 of the large-diameter pipe ⁇ serves as a stopper for preventing the small-diameter pipe from coming off, and the small-diameter pipe does not move.
- stable sliding becomes possible.
- the projection 3 shown in FIG. 1 can be easily formed by pressing a matured edge of a matured knife on a required portion of the large-diameter pipe 1.
- the diameter of the tip 5 can be easily reduced by using a mold. Of course, such forming is done mechanically.
- the embodiment shown in FIGS. 3 and 4 is a suction pipe in which only the flange 4 is formed at the inner end of the small-diameter pipe 2 inserted into the large-diameter pipe. Even when the synthetic resin material forming the large-diameter pipe 1 and the small-diameter pipe 2 is changed, air suction and liquid leakage due to the generation of voids do not occur.
- the large-diameter pipe 1 has a melt flow index of 5 to 15 gf Z 10 min (JISK 6758). Formed on a resin composition consisting of 5-30% by weight of ethylene propylene elastomer and 70-95% by weight of ethylene copolymer block copolymer, having a small diameter

Together with the pipe 1, the inner surface of the pipe 2 and the inner end of the small-diameter pipe 2 are completely adhered.
- melt flow index of the resin composition in a large-diameter pipe was set to 5 to 15/10 min was because of the moldability and the close contact with the small-diameter pipe. Therefore, if the melt flow index is less than 53 ZIOB in, the productivity will decrease and the adhesion of large and small diameter pipes will be reduced. Is impaired. If the diameter exceeds 15 3/10 min, the dimensional accuracy is deteriorated, and the slip between the large and small diameter pipes is also poor.
- the ethylene propylene elastomer in the resin composition is mainly composed of ethylene and propylene, and further contains a diphenyl olefin, a cyclic gen hydrocarbon, and the like.
- the copolymer is more elastic when the ethylene content is 20 to 80% by weight. I like it.
- the ethylene concentration is not 10% by weight, the elasticity is low. They tend to be short, and on the other hand, exceeding 40 weight percent is not preferred because it is too elastic.
- the ethylene propylene elastomer is less than 5 parts by weight in the resin composition, the elasticity is insufficient, and when it exceeds 30 parts by weight, the molding stability is reduced and the dimensional accuracy is deteriorated. The shadows will come.
- the propylene homopolymer of a small-diameter pipe has a strong waist, and the flange 4 adheres to the inner surface of the large-diameter pipe.
- the index is 7? If it is less than 10 ni in, productivity will decrease and adhesion to large diameter pipes will be poor.If it exceeds lA gf ZIO min, dimensional accuracy will deteriorate. Slip between large and small diameter pipes becomes worse, and both are not preferred ⁇
