Abstract
The utility model discloses a passenger car air-condition with a hose capable of being conveniently assembled. The passenger car air-condition with the hose capable of being conveniently assembled comprises a hose clamp locating piece and an elastic hose clamp. A locating groove and an installation groove are arranged in the connecting end. A clamping groove is arranged in the locating groove. An O-shaped seal ring is sleeved in the clamping groove. The hose is sleeved with the locating groove in a fitting mode. The inner wall of the hose abuts against the O-shaped seal ring. The hose clamp locating piece comprises an installation end and a locating arm, wherein the installation end and the locating arm are integrated. The elastic hose clamp is in a circular ring shape. A reversed clamp and a reversed hook are arranged at the outer side of the circular ring, wherein the reversed clamp and the reversed hook are buckled in the fitting mode.
