Abstract
The utility model discloses a child cart. The structure of a cart frame is optimized. When the frame is transformed from an unfolding state to a folding state, only locking mechanisms need to be unlocked, sliding pieces are made to slide along rear fulcrum bars, and thus connecting rods and oblique stay bars move upwards and make rotation along with the sliding pieces and drive front fulcrum bars to be shortened relative to push rods at the same time. The push rods rotate around the rear fulcrum bars to achieve folding of the frame in the front-back direction, and bottom stay bars move upwards along with the connecting rods simultaneously to achieve folding of the frame in the left-right direction. The child cart is simple and compact in structure, the frame can be folded and unfolded conveniently, and the cart frame is small in standing space and small in occupied space after being folded.
