Abstract
The utility model discloses a resistance-free flower drum for body-building equipment, essentially consisting of a revolving body, a flower drum body, a mono-directional rotor and a shaft center. The mono-directional rotor is positioned in the flower drum body. The revolving body matches with and penetrates through the mono-directional rotor. The shaft center passes through the revolving body and can rotate relatively to the revolving body. The flower drum body has a pressure regulating through hole. A pressure regulating block pressed against the revolving body is arranged at an opening at the interior end of the pressure regulating through hole, in which an elastic body is provided, with one end elastically pressing against the pressure regulating block and the other end elastically resting against a pressure regulator at an opening at the exterior end of the pressure regulating through hole. With the arrangement of the mono-directional rotor, when moving, the revolving body drives the flower drum body to rotate, and then the flower drum body drives a cast wheel to rotate; when stopping, the flower drum body revolves relatively to the revolving body with sharply reduced revolving force, the great inertia from the cast wheel can not be transferred to a chain wheel and the pedals can not impact and injure the heel knees of the exerciser. The flower drum has simple structure and reliable function.
