Hose connecting structure |
摘要 |
A hard pipe has an annular stop projection formed about its portion press fitted in a flexible hose to make a hose connecting structure. The projection has a cross sectional contour including a gentle outward slope extending from the front end of the projection to a first corner, which makes the angle of the subsequent second corner gentle, and a rear face at the second corner extending inwardly toward the longitudinal axis of the pipe at right angles thereto. The hose connecting structure has high levels of pull-out strength and sealing properties without having the hose damaged by the projection on the pipe.
