Brake mechanism of baby carriage

Abstract

The brake mechanism comprises a connecting pipe, a brake handle and a transmission mechanism, the brake mechanism further comprises a rotating piece which is arranged outside the connecting pipe in a sleeving mode and can rotate relative to the connecting pipe and a first reset piece used for enabling the brake handle to rotate and reset, the rotating piece is in a ratchet wheel shape, and a plurality of ratchet grooves are formed in the peripheral face of the rotating piece; the brake handle is rotationally connected with a pawl which is always pressed to the peripheral surface of the rotating piece, the brake handle can drive the rotating piece to do one-way intermittent motion, and the rotating piece rotates once along with the brake handle when the brake handle rotates once in the forward direction; the transmission mechanism comprises a linkage part which is arranged on the connecting pipe and can axially slide relative to the connecting pipe, and the linkage part can be driven to axially move outwards or inwards every time the rotating part rotates once, so that the braking part enters and is kept in a braking state or a braking releasing state; the brake operation and the brake release operation are both treading operation, so that the operation is more convenient and quicker.
