Abstract

A fast hose connector comprises a guide tube and an arresting tube movably fitted over the guide tube. The arresting tube is provided in the inner wall thereof with two elastic retaining bodies capable of releasably arrest a tube that is inserted into the guide tube via the arresting tube. As the arresting tube is pressed to slide downward along the guide tube, the elastic retaining bodies become disengaged with the tube so as to enable the tube to be pulled out of the connector.

Claims

1. A fast hose connector comprising:

a guide tube provided in an outer wall thereof with an upper guide ring, a lower guide ring, a stop ring, two longitudinal guide slots extending from said upper guide ring to said stop ring, and two through holes located under said upper guide ring in said guide slots in such a manner that said two through holes are in communication with an interior of said guide tube, with each of said two through holes being provided in a top edge thereof and a bottom edge thereof with a slanted surface which is located in the outer wall of said guide tube and is provided with a pointed edge, said upper guide ring and said lower guide ring further provided with two protrusions opposite in location to each other; and

an arresting tube provided in an inner wall thereof with two elastic retaining bodies opposite in location to each other and extending from a bottom edge of the inner wall of said arresting tube, said two elastic retaining bodies being provided at a top end thereof with an enlarged portion having a retaining recess and a slanted stop surface, said arresting tube further provided in the inner wall thereof with two longitudinal locating slots opposite in location to each other whereby said arresting tube is movably fitted over said guide tube such that at least said enlarged portions of said elastic retaining bodies are received in said guide slots and said protrusions of said guide tube are located in said locating slots of said arresting tube, and that said enlarged portion of said elastic retaining bodies of as said arresting tube is movably fitted over said guide tube said arresting tube is received in said through hole of said guide tube, and further that said retaining recess of said enlarged portion of said elastic retaining bodies of said arresting tube retains said pointed edge of said slanted surface of said through holes of said guide tube, and further that said enlarged portions of said arresting tube are extended into said guide tube;

said enlarged portions of said elastic retaining bodies of said arresting tube being intended to arrest releasably a tube inserted into said guide tube via said arresting tube such that said enlarged portions of said elastic retaining bodies are retained in a recessed wall of the tube so as to locate the tube, and that said elastic retaining bodies slide along said slanted surfaces of said guide tube to cause said enlarged portions to move away from the recessed wall of the tube so as to enable the tube to be pulled out of said guide tube and said arresting tube at such time when said arresting tube is pressed by an external force to slide until said arresting tube is stopped by said stop ring of said guide tube, and further that said two elastic retaining bodies return to original positions thereof by virtue of elasticity thereof at such time when said arresting tube is relieved of the external force exerting thereon.
