Abstract
A quick coupling (100) comprising a first element (50) and a second element (60) which may be separably coupled is described; the first element (50) mainly including an external sleeve (1) with hooking means (3), a connector (2) for user interface (25), and at least one valved coupling (16) for at least one pressure line (9, 10), the second element (60) mainly including hooking means (13, 15, 70), at least one valved coupling (17) for at least one pressure line (20, 21), and a connector (12) for user interface (122). Said second element (60) further comprises a safety ring nut (11) along the circumference of which safety pins (14) are provided, adapted to be pushed by said hooking means (15, 70) into seats (4) of the external sleeve (1).
Claims11
Quick coupling (100) comprising a first element (50) and a second element (60) that can be separably coupled,
- the first element (50) providing principally an external sleeve (1) with hooking means (3), a connector (2) for user interface (25), and at least a valved coupling (16) for at least one line in pressure (9, 10),
- the second element (60) providing principally hooking means (13, 15, 70), at least one valved coupling (17) for at least one line in pressure (20, 21), and a connector (12) for user interface (122),
- characterized in that
- said second element (60) comprises also a safety ring nut (11) along the circumference of which safety pins (14) are provided suitable to be pushed by said hooking means (15, 70) in seats (4) of the external sleeve (1).
Process for quick coupling of a first element (50) in a second element (60) comprising valved couplings (16, 17) for lines in pressure (9, 10, 20, 21), characterized in that it provides the rototraslatory engagement of hooking means (70, 13, 15) of the second element (60) in helicoidal grooves (3) of an external sleeve (1) of the first element (50), and simultaneously the engagement, by pushing of said hooking means (70, 13, 15), of safety pins (14) of a safety ring nut (11) of the second element (60) in seats (4) of the external sleeve (1), when the coupling is achieved the rotation of the hooking means (13) is prevented in respect of the external sleeve (1) except that the safety ring nut (11) is activated.
