PIPE CONNECTING STRUCTURE AND BLOWGUN WITH THIS STRUCTURE

PROBLEM TO BE SOLVED: To constitute a pipe connecting structure such as FRP of a connecting structure between pipes of equal inner diameters keeping an appropriate connecting force even if inner or outer diameter at the connected part shows a certain disturbance and its fixing or removal can be easily carried out without reducing the connecting force even under its use for a long period of time.SOLUTION: A disturbance of diameter at a connecting part is eliminated by arranging an elastic body at a connecting part between the pipes to hold a stable connecting force. Since it is possible to hold the stable connecting force for a long period of time by applying this connecting structure to a blowgun and the like, it does not require any repair due to wear at the connected part. In addition, it is possible to provide a blowgun that is compact in size, shows a superior carriage function and is light in weight.SELECTED DRAWING: Figure 1 【課題】内径の等しい管体間の継ぎ構造において、継合部の内外径にばらつきがあっても適度な継合力を保ち、また長期にわたる使用においても継合力を低下させることなく、着脱が容易に行えるFRPなどの管体の継ぎ構造を構成する。【解決手段】管体間の継合部に弾性体を設けることによって継合部の径のばらつきを吸収し、安定した継合力を保持する。この継ぎ構造を吹矢などに応用することにより、安定した継合力を長期間にわたって保持できるため、継合部の磨耗などによる補修が不要になる。また、コンパクトで持ち運び性に優れ、しかも軽量な吹矢を提供できる。【選択図】図１
