Abstract

A quick-mounting pipe structure comprises a first tubular fitting, a coupling sleeve, and a hose assembly. The first tubular fitting includes a locking ball. The coupling sleeve is formed with an inner annular protrusion and internal threads at an inner surface thereof. The hose assembly includes a hose and a second tubular fitting. The second tubular fitting is formed with an annular raised portion, an annular recessed portion, and external threads on its outer surface. The second tubular fitting can be inserted into the first tubular fitting to allow the locking ball to be retained in the annular recessed portion of the second tubular fitting. Additionally, the coupling sleeve can be threadedly engaged with the second tubular fitting, thereby providing additional attachment between the first tubular fitting and the second tubular fitting to prevent the second tubular fitting from being pulled out of the first tubular fitting under excessive force.
