Reference numeral 1 denotes a male duct in which a large-diameter cylindrical portion 2 and a frustoconical cylindrical portion 3 are continuously provided at the end, and a longitudinal rib 4 and a guide rib 5 which are crushed along the parting line of the male duct 1 are continuously formed. It is protruding. Reference numeral 6 denotes a female duct, which is provided with a truncated conical cylinder portion 7 inscribed by the truncated conical cylinder portion 3 and a large-diameter cylindrical portion 8 inscribed by the large-diameter cylindrical portion 2 which are connected to each other at the end of the female duct 6. As shown in FIG. 4, a vertically elongated rib 9 is provided along the parting line by a mold 12, and a bulge receiving portion 10 for fitting the guide rib 5 is formed at the tip of the mold 12 as shown in FIG. ing.
【０００６】 接続時は雄型ダクト１のガイドリブ５を雌型ダクト６の膨出受部１０に挿入し て位置決めし、雄型ダクト１の截頭円錐筒部３を雌型ダクト６の截頭円錐筒部７ 内面に当接する。この時、雄型ダクト１の大径円筒部２は雌型ダクト６の大径円 筒部８に嵌合しシ−ルされる。At the time of connection, the guide rib 5 of the male duct 1 is inserted into the bulge receiving portion 10 of the female duct 6 for positioning, and the frustoconical cylindrical portion 3 of the male duct 1 is truncated at the female duct 6. It contacts the inner surface of the conical cylinder 7. At this time, the large diameter cylindrical portion 2 of the male duct 1 is fitted into the large diameter cylindrical portion 8 of the female duct 6 and sealed.
【０００７】 図６は本考案の第２実施例で、雌型ダクト６に伸縮性蛇腹１１を設けシ−ル性 を向上させている。他の構造は第１実施例と同様である。FIG. 6 shows a second embodiment of the present invention in which a female duct 6 is provided with an elastic bellows 11 to improve the sealing property. The other structure is similar to that of the first embodiment.
【０００８】[0008]
本考案によると、雄型ダクトの端末に大径円筒部と截頭円錐筒部を連設し、該 雄型ダクトのパ−ティングラインに沿って縦長リブとガイドリブを連続して突設 し、雌型ダクトの端末に、前記截頭円錐筒部が内接する截頭円錐筒部と、前記大 径円筒部が内接する大径円筒部を連設し、該雌型ダクトのパ−ティングラインに 沿って縦長リブを突設し、その先端に前記ガイドリブを嵌合する膨出受部を形成 してあるので、接合部が截頭円錐筒状にしたことにより、成形時パリソンが截頭 円錐筒部に沿って風船玉のように膨らみ、それ以上引き伸ばされないので薄肉防 止、強度アップとなり、シ−ル材を用いないでシ−ル性を向上でき、膨出受部と ガイドリブにより位置決めを行い嵌合度を高めることができ、又、パ−ティング ラインよりなる潰し一体縦長リブの為にダクトの割れ防止となる。 According to the present invention, a large-diameter cylindrical portion and a truncated cone cylindrical portion are continuously provided at the end of the male duct, and vertically long ribs and guide ribs are continuously projected along the parting line of the male duct. At the end of the female duct, a frustoconical cylinder part inscribed by the frustoconical cylinder part and a large-diameter cylindrical part inscribed by the large-diameter cylindrical part are connected in series, and on the parting line of the female duct. A vertically long rib is provided along with a bulge receiving part that fits the guide rib at the tip of the rib.Therefore, the joint is shaped like a truncated cone so that the parison is shaped like a truncated cone. Since it bulges like a ball along the part and is not stretched anymore, it prevents thin wall thickness and improves strength.The sealability can be improved without using a sealing material, and positioning is performed by the bulge receiving part and the guide rib. It is possible to increase the degree of mating by using a parting line. And the crack prevention of the duct for the integrated longitudinal ribs.
