Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a child cart which is easy to assemble and disassemble. Background Art

[0002] A child stroller is a ride-on stroller for infants and young children. It can reduce the burden of holding or carrying the child when parents take the child out, and also provide better comfort and safety for the child. In order to further improve the comfort of the child in the stroller, the existing child stroller is provided with a larger storage space on the frame, and then the frame is enclosed by a cloth, and the child is placed in the storage space. The child can sit, lie down, or play with toys according to his or her preferences, and the parent can push the frame by cooperating with the handrails provided above the frame and the pulley assembly provided below the frame.
