QUICK-CONNECT COUPLING FOR ARTICULATING HOSE LINES

摘要

A quick-connect coupling for articulating hose lines includes a coupling body having a bore therein which receives a stem attached to a hose to be coupled to the body. A spline is positioned within the bore which receives a spline on the stem so that the stem does not rotate with respect to the bore and coupling body. A coll et is provided which has inwardly and outwardly projecting detents that simultaneously engage both a shoulder within the bore and a groove in the stem to prevent axial movement of the stem with respect to the bore. While the stem is thus retained w ithin the bore, an O-ring seals with the surface of the stem. In order to disconnect t he stem from the bore, a collet is pressed inwardly to disengage the detents and then th e stem is pulled axially away from the coupling member. By providing a quick-connect coupling in which a stem does not rotate with respect to a coupling member, the collet which is used to lock or latch the stem and coupling member axially to one anoth er is not worn and stressed by relative rotation between the stem and coupling member so as to threaten the integrity of the coupling.
