Abstract
The utility model discloses a speed-adapting decelerating and braking mechanism for a baby carrier. The speed-adapting decelerating and braking mechanism comprises small centrifugal steel balls and a centrifugal conversion force-amplifier. According to the centrifugal conversion force-amplifier, centrifugal component force is converted into tensile force of a horizontal connecting rod after being increased through hinging of a slant rigid pull rod, a vertical rigid pull rod and a horizontal rigid connecting rod, so that horizontal movement of a brake hub is realized. Wear-resistant rubber is arranged at the left end of the brake hub; the brake hub horizontally moves leftwards to be attached to a brake block; the brake block is fixed to a casing on a frame in a way of being connected with the right end of the brake hub through a spline structure; a clamping groove is formed in the left end of the casing; one end of a spring is clamped in the clamping groove, and the other end of the spring is clamped at the right end of the brake hub. The casing rotates relative to a rear wheel axle through the bearing.
