Angle recognition type rotation operating force smooth constant damper

The utility model discloses an angle recognition type rotation operating force smooth constant damper which comprises a base, a rotating shaft and an end cover. A first damping cavity is formed in the base to serve as a shaft hole of the rotating shaft and used for the rotating shaft to rotate therein. A rotating core is arranged at one end of the rotating shaft, the interior of the first damping cavity is coated with a grease layer enabling smooth constant damping force to be generated between the rotating core and the base, and the rotating shaft is provided with a sealing ring. The base is connected with the end cover to form a box body of the damper, a sliding seat portion stretches outwards from the side wall of the box body in the direction perpendicular to the rotating shaft axis line, a flexible induction unit is arranged in the sliding seat portion in a flexible sliding mode, the other end of the rotating shaft stretches out of the box body and is fixedly sleeved with a touch induction unit which rotates along with the rotating shaft and used in cooperation with the flexible induction unit in a touch mode to induce the rotation angle of the rotating shaft. According to the angle recognition type rotation operating force smooth constant damper, smooth and constant damping is formed between the inner rotating matched components of the damper, and the angle recognition type rotation operating force smooth constant damper is simple in structure, convenient to mount and capable of recognizing the rotation angle of the rotating shaft.
