An adjustable damping quick-acting hinge (1) comprises a first hinge quadrilateral (2) comprising: a coupling element (3) associable with a fixing element (100); a first portion (4a) of the first rod (4) and a third rod (5), associated in an articulated manner with the coupling element (3); and a first portion (6a) of a second rod (6) interposed between and hinged to the two rods; and the hinge further comprises a second hinge quadrilateral (11) comprising: a fixed element (12) associable with an element (200) movable relative to the fixed element (100); a second part (6b) of the second rod (6) and a fourth rod (13), which are associated in an articulated manner with the fixing element (12); and a second portion (4b) of the first rod (4) interposed between and hinged to the two rods. The hinge (1) is adapted to alternately assume an open configuration and a closed configuration, the rods (4, 5, 6, 13) rotating about respective hinge pivots (7, 8, 9, 10, 14, 15, 16) which are substantially parallel to one another, and the fixing element (12) changes its own arrangement by an aperture angle during movement between the open configuration and the closed configuration. The hinge (1) is further provided with first elastic compression means (17) associated with the first quadrilateral (2) and second elastic compression means (18) associated with the second quadrilateral (11). Either or both of the first and second elastic means (17, 18) are interposed between the coupling element (3) or the fixing element (12) and an abutment element (29) associated with at least one rod of the first or second quadrilateral (2, 11), and the hinge (1) comprises at least one assembly (30) for adjusting the preloading of the first or second elastic means (17, 18), the assembly comprises: a movable element (31) supporting an abutment element (29) and associated with at least one rod of the first or second quadrilateral (2, 11); and at least one pusher element (32) interposed between the third or fourth rod (5, 13) and the movable element (31), a change in position of the movable element (31) actuated via the pusher element (32) being adapted to change the preloading of the first or second elastic means (17, 18).
