The invention comprises an operating lever, a connecting shaft, a torsion spring, at least a pair of damping fins, an axle sleeve, a disk spring, a fixed casing body and an adjusting nut, one end of the connecting shaft is firmly arranged on the operating lever, the fixed casing body penetrates through the other end of the connecting shaft and an external thread is arranged on the fixed casing body, the torsion spring is suited on the connecting shaft and one end of the torsion spring is firmly connected with the operating lever, the axle sleeve interference is suited on the outer side of the torsion spring in a matching way, at least a chord cross section is arranged on the peripheral outer side wall of the axle sleeve, the disk spring is arranged on the right side edge of the axial direction of the axle sleeve, a plurality of positioning grooves are arranged onthe fixed casing body, the damping fin comprises a male damping fin and a female damping fin, the male damping fin is firmly connected with the axle sleeve, the female damping fin is firmly connectedwith the fixed casing body, the adjusting nut is arranged on the connecting shaft on the outer side of the fixed casing body.

Description

technical field [0001] The invention relates to a damping device for a rotating cover and a rotating door and window used for opening and closing by a hinge, in particular to a damping device for limiting one-way rotation speed. Background technique [0002] The Chinese patent CN1456826A disclosed on November 19, 2003 discloses a damping device, which is installed in a housing in which a raised spacer is formed radially on the inner wall of the cylinder, and is rotatably installed with a rotary blade with a check valve. Component, one end side of the housing forms an opening that can be inserted into the rotating component, and at the same time, a side wall portion is provided on the other end side, and a diameter smaller than the above-mentioned side wall is formed on the side wall for rotatable rotation of the rotating shaft of the rotating component. The small-diameter through hole of the opening part supported by the shaft, and the opening part of the housing is sealed b...
