Abstract

The invention discloses a quick connector, which comprises a connector body, a water outlet connector, and small and big detachable clamping rings mounted on the connector body and the water outlet connector respectively. The water outlet connector is inserted in the back end of the connector body by extruding an elastic side wing of the small clamping ring on the water outlet connector, and the elastic side wing of the small clamping ring is embedded in a hole on the back end of the connector body due to outwardly extended elasticity thereof, so that the water outlet connector is fixedly connected with the connector body in tight manner. An elastic side wing of the big clamping ring is pressed, and a pressing block on the elastic side wing of the big clamping ring is greater in thickness than the connector body, so that the elastic side wing of the small clamping ring will be pressed down to drag the water outlet connector so as to separate the connector body from the water outlet connector. Because the small and big clamping rings are both in C ring structures, the small and big clamping rings can be conveniently detached from the connector body and the water outlet connector so as to be conveniently repaired and replaced. The invention also discloses a connecting method using the quick connector.
