Abstract
A simple connecting hose for fluid transportation pipe comprises a high pressure hose (1) and connecting heads (2,3) set on both ends of the high pressure hose. One of the connecting heads includes a first housing (31), a second housing (32) and a connecting sleeve (33), each one of which has an inner liquid passage. The two ends of the connecting plug are mounted inside the first and the second housing respectively and therefore all the liquid passages are communicated with each other. The axis of the first housing is in parallel with or coincides with that of the connecting plug and intersects the axis of the second housing. Sealing elements are provided between the exterior wall of the connecting plug and the corresponding liquid passages. At least one of the two housings can freely rotate along the circumference of the connecting plug. Because the high pressure hose does not rotate together with the other parts of the simple connecting hose during assembling, it is convenient for installation.
