【考案の詳細な説明】
この考案は農園に薬液類を散布するための散布竿の改良
に係り、その目的とするところは散布竿におけるアルミ

可撓性ホースの接続部におけるホース部の切損なき噴霧
竿を提供しようとするものである。[Detailed explanation of the invention] This invention relates to the improvement of a spraying rod for spraying chemical liquids on farms.The purpose of this invention is to improve the joint fittings at both ends of a hard pipe such as aluminum in the spraying rod, and the flexible parts inside the pipe. It is an object of the present invention to provide a spray rod that does not cause breakage of the hose portion at the connection portion of the flexible hose.
以下この考案の実施例を添付図面に基いて説明する。Embodiments of this invention will be described below with reference to the accompanying drawings.
第１図は噴霧竿Ａの１例の全体を示し、第２図は同上の
一部切欠拡大、第３図は同上の一端の更に拡大した断面
であり、１はアルミパイプ、２ａ、２ｂはパイプ両端の
ジヨイント金具である。Figure 1 shows the whole of one example of spray rod A, Figure 2 is an enlarged partial notch of the same, and Figure 3 is a further enlarged cross section of one end of the same. 1 is an aluminum pipe, 2a and 2b are These are joint fittings on both ends of the pipe.
そしてジヨイント金具２ａは雄型、ジヨイント金具２ｂ
は雌型である。The joint metal fitting 2a is male type, and the joint metal fitting 2b is a male type.
is female.

ス凹条７を施しである。A polyethylene hose 3 is connected to both the joint fittings 2 a and 2 b inside the pipe 1, and the small diameter portion 4 at the inner end of the joint fittings has a ridge-shaped protrusion 5 formed on its outer circumferential surface. The small diameter portion is press-fitted into the end of the hose, and a plastic metal tube 6 is externally fitted to the end of the hose, and discontinuous press grooves 7 are provided on the entire circumferential surface of the tube.
両ジヨイント金具とホースの接続は、予め一方のジヨイ
ント金具をホースの一端に取付け、次にホースをパイプ
内に通しパイプ他端に僅かに突出させると共にホースの
伸縮弾性を利用して所要長さ引張り出した状態で他端に
他方のジヨイント金具を取付ける。To connect both joint fittings and a hose, attach one joint fitting to one end of the hose in advance, then pass the hose through the pipe and slightly protrude from the other end of the pipe, and use the elasticity of the hose to pull it to the required length. With it extended, attach the other joint fitting to the other end.
両ジヨイント金具をパイプ端に固定した状態ではホース
がパイプ内で若干たるむが何等支障がないのみならず切
損防止に反って好都合である。When both joint fittings are fixed to the ends of the pipe, the hose will sag slightly inside the pipe, but this is not only a problem but also convenient for preventing breakage.
図中８はジヨイント金具２ａ、２ｂをパイプ１に固定す
るビスである。In the figure, 8 is a screw that fixes the joint fittings 2a, 2b to the pipe 1.
又図示のジヨイント金具はプラスチックの成形前とし、

る。Also, the joint fittings shown are before plastic molding,
Only the threaded portions 9a and 9b are made of metal and inserted during molding.

損事故を防止できるという効果がある。This device has the above-mentioned structure, and this device forms a ridge-shaped protrusion on the small diameter portion of the base end of the joint fitting, press-fits the hose end into this small diameter portion, and further attaches a flexible metal tube to the hose end. Since the hose is fitted externally and discontinuous press grooves are applied to the entire circumference of the metal cylinder, the hose partially enters the recess formed by the harpoon-shaped protrusion of the joint fitting, which makes it a strong stop for the hose to come out. Since the intrusion is not large enough to cause a cut in the hose, it has the effect of preventing breakage accidents at the connection part of the hose with the joint fitting over a long period of time.
