摘要： A quick coupling device comprises a main body (2) and an outer sleeve (17) arranged around the main body (2). The main body (2) comprises a first body (2A) and a second body (2B), which are shaped to removably engage with each other at a junction area. In an engaged configuration of the main body (2), the outer sleeve (17) is slidingly movable on said main body (2) between a retaining position, wherein it is located around the junction zone and prevents release of the first body (2A) from the second body (2B) along a direction transverse to an axial direction, and a release position, wherein the outer sleeve (17) is spaced apart from the junction area and allows release of the first body (2A) from the second body (2B) along said transversal direction.

摘要： The present invention relates to a quick coupling (1) for profiled or threaded terminals (2), comprising a substantially tubular main body (3) internally delimiting a passage conduit (4) for a fluid and extending along a main axis (X-X), and a jaw (14) engaged to the main body (3). The jaw (14) operates between a first unhooked position from the terminal (2), in which it does not constrain the terminal (2) to the quick coupling (1), and a second hooked position to the terminal (2) in which it constrains the terminal (2) to the quick coupling (1). The jaw (14) comprises a plurality of pins (10) housed in respective radial seats (9) defined at a first end (5) of the main body (3). The pins (10) are configured for sliding internally of said radial seats (9) and have a profiled or threaded radially internal end (11) that is configured for being coupled to the profiled or threaded terminal (2). In the second position of the jaw (14) the profiled or threaded radially internal end (11) of the pins (10) is engaged to the terminal (2) so as to retain the terminal (2) in engagement to the quick coupling (1). The quick coupling (1) further comprises at least an activating device (16, 17) that is operatively engaged with said at least a jaw (14) for determining the passage of the jaw (14) between the first and the second position and hooking/unhooking devices (15, 18, 21, 31) configured for operating on the auxiliary body (16) so as to regulate the relative axial position between the auxiliary body (16) and the main body (3).

摘要： The present invention relates to a quick coupling (1) for smooth terminals. The quick coupling (1) comprises a main body (2) defining a passage conduit (7) for a fluid destined to cross the quick coupling (1) and configured for being coupled to a circuit, a tubular body (3) engaged to the main body (2) and configured for being removably coupled to a smooth terminal (4) and a jaw (16) engaged to the tubular body (3). The jaw (16) is configured for operating between at least a first unhooked position from the terminal (4), in which it does not axially constrain the terminal (4), and a second hooked position to the terminal (4) in which it is locked onto, and axially constrains, the terminal (4) to the tubular body (3). The lever (27) is activatable about a fulcrum (28) borne by the tubular body (3), and operates on the main body (2) for axially displacing the main body (2) with respect to the tubular body (3). The activation of the lever (27) further determines an axial sliding of the jaw (16) with respect to the tubular body (3) and the passage of the jaw (16) from the first unhooked position to the second hooked position.

摘要： The present invention relates to a quick coupling comprising: a substantially tubular main body (3) internally delimiting a passage conduit (C) for a fluid, where the main body (3) has a first end (6) configured for removably connecting to a terminal (2) and a second end (7) opposite the first end (6) and configured for connecting with a circuit; a plurality of jaws (13) arranged about a main axis (X-X) of the passage conduit (C) and operatively engaged with the main body (3) at the first end (6), wherein each of the jaws (13) is radially mobile with respect to the main body (3) between a first unhooked position from the terminal (2) and a second hooked position to the terminal (2); activating devices (21 ) operatively engaged with the jaws (13) for determining passage between the first position and the second position. A guide ring (11) coaxial to the main body (3) has radial guides (12) engaged to the plurality of jaws (13) for radially guiding the jaws (13) during movement between the first and the second position.
