A quick coupling comprises a male connector and a buckle. The coupling further comprises a female connector. The male connector is of a vertically-penetrating hollow structure and comprises a connecting pipe, a first hose connecting part, an outer stop ring and an inner clamp ring. The first hose connecting part is arranged at the upper end of the connecting pipe. The upper middle portion of the connecting pipe is sleeved with the outer stop ring. The inner clamp ring is located below the outer stop ring and arranged at the middle portion of the connecting pipe in a sleeving manner. The buckle comprises a pressing part, a clamping and connecting part and a connecting strip. The female connector is of a vertically-penetrating hollow structure and comprises an opening structure and a second hose connecting part. The opening structure is located above the second hose connecting part. A vertically-penetrating circular opening is formed in the middle portion of the opening structure. Each of the left side and the right side of the opening structure is provided with a left-right penetrating buckle installing opening. The quick coupling is simple in structure and convenient to use.
Description
technical field [0001] The invention belongs to the field of pipeline connection, in particular to a quick joint.
