The utility model discloses a torsion spring rotating damper, which comprises a sleeve, an upper cover, a lower shell, a rotating shaft mechanism, a torsion spring and a tail pin. The rotating shaft mechanism comprises a flat position and a rotating shaft. The lower shell is provided with a capacitive cavity, the flat position is located above the lower shell, the rotating shaft is inserted into the capacitive cavity, the upper end of the lower shell is provided with an upper cover, the rotating shaft mechanism passes through the upper cover, and the torsion spring is installed. Installed on the outer surface of the lower shell, the upper end of the torsion spring is fixed on the flat position, and the lower end of the torsion spring is fixed on the outer surface of the lower shell; the rotating shaft of the rotating shaft mechanism is axially symmetrically equipped with two blades, the inner wall of the chamber is symmetrically equipped with two ribs, the blades and ribs are matched, and the buffer space of the chamber is filled with viscous fluid. The utility model has the advantage that the tail pin is fixed on the moving part because of the torsion spring. When the moving part rotates, the blade on the rotating shaft will block the flow of viscous fluid in the lower shell, and generate damping force. At the same time, the torsion spring also generates torsion force. Through the dual functions of the torsion spring and the blade, the moving part will play a slow role in the descending process. Descending effect.
