Abstract

The utility model discloses a child pushing cart. The utility model comprises a pushing cart frame, a front wheel and a back wheel. The pushing cart frame comprises a base frame which is arranged at the bottom extending backwards and forwards, and a front support the lower end of which is in rotary connection with the front part of the base frame. The front wheel is arranged on the front lower part of the base frame, and the back wheel is arranged on the back lower part of the base frame. Two front supports are respectively arranged on both sides of the pushing cart. A locking device is arranged on the rotary connection position of the front supports and the base frame. The lower end of the front support is in rotary connection with the front part of the base frame, and the rotary connection position is provided with the locking device. That is the reason why the front support and the base frame are locked by the locking device when unfolded. The pushing cart frame has the advantage of relatively simple structure, with the quality of being folded and unfolded easily.
