Quick coupling ball-and-socket joint for pipes

Abstract

The joint comprises two components to be coupled together, namely a male component and a female component joined to respective pipes. These two components are coupled together by a third component which comprises: an annular element (21) which embraces the male component and engages it in a transverse plane, and at least two coupling means (30, 30′) for hooking the female component, each comprising two parallel hooking arms (31) in the form of plates which lie in planes parallel to the axial plane (P) passing through the longitudinal centre line of the coupling means (30, 30′). In addition there is provided a pair of flanges (41) for each coupling means (30, 30′) in the form of plates firmly joined to the annular element (21) and lying in planes parallel to the planes defined by the hooking arms (31), said pair carrying a transverse pin (42) for securing the hooking arms (31) in an axial direction. Means are also provided for applying axial traction to the coupling means (30, 30′) in order to firmly join the male and female components together. According to the invention, said flanges (41) are applied on the outside of the outer faces of the hooking arms (31). The ball-and-socket joint obtained in this manner, and in particular its third component, is able to better support the pressure, especially if relatively high, to which the pipe is subjected.
