Abstract
The present invention discloses a centrifugal brake mechanism, including a wire reel; a brake ring assembly, arranged on one side of the wire reel; and a centrifugal brake assembly, including a centrifugal seat connected to the wire reel and at least two centrifugal arms, wherein the centrifugal arm is rotatably connected to the centrifugal seat and is capable of swinging vertically relative to the centrifugal seat; and at least one centrifugal bean having a polygonal cross-section is also rotatably connected to the centrifugal arm, so that a swing angle of the centrifugal arm relative to the centrifugal seat is automatically adjusted according to the rotation speed of the wire reel, thereby adjusting a contact area between the centrifugal bean and the brake ring assembly, and then the rotation speed of the wire reel may be automatically fine-tuned to maintain a dynamic balance with the brake forces.
