Abstract
The utility model discloses an infant wheelbarrow, which comprises a wheelbarrow frame and wheels. The wheelbarrow frame comprises a plurality of wheel supports and a brake mechanism is arranged between the wheel and the wheel support. The brake mechanism comprises a plurality of locking holes arranged on the wheel, a locking pin arranged on the wheel support and a control member slidably arranged along the linear direction on the wheel support. At least one of the control member and the locking pin is equipped with an inclined plane. A locking pin elastic member is arranged between the locking pin and the wheel support. A control member elastic member is arranged between the control member and the wheel support. The elastic force of the control member elastic member is greater than the elastic force of the locking pin elastic member. The wheelbarrow frame is equipped with a manual control mechanism for controlling the conversion of the brake mechanism from a brake position to a brake-releasing position. When the two hands of a user are separated from the wheelbarrow frame including the manual control mechanism, the control member is slid under the action of the control member elastic member so as to drive the brake mechanism to converting from the brake position to the brake-releasing position. The infant wheelbarrow is simple in structure and safe in usage.
