| 摘要 |
The present invention relates to a quick-fit coupling (1) for smooth or threaded fittings, which comprises a tubular body (3) which delimits internally a passage duct (11) for a fluid and which has a first end (6) configured to be connected to a circuit and a second end (7) configured to be removably connected to a fitting (2), at least one clamp (27) which is functionally engaged with the tubular body (3), said clamp (27) operating between at least one first position of disengagement from the fitting (2) in which it does not axially bind the fitting (2) and a second position of coupling to the fitting (2) in which it is tightened on, and axially binds the fitting (2) to, the tubular body (3), said at least one clamp (27) comprising a radially elastically deformable and/or flexible open annular element (28). The quick-fit coupling (1) further comprises a plurality of thrust pins (31) configured to determine the transition of the clamp (27) between the first position and the second position and an activation device (32) configured to operate on said plurality of thrust pins (31) so as to cause the transition of the clamp (27) between the first position and the second position. |
