A folding play crib structure comprising frame tubes, corner joints, middle joints, central bottom joint, U-shaped tubes, V-shaped pull rods, bottom cross tubes and leg joints. One end of the frame tube is pivotally connected with an insert seat which cooperates with the joints for controlling the locking and folding of the crib structure. The U-shaped tubes are pivotally connected at the central portion of the bottom cross tubes to enhance the supporting effect for the bottom of the crib structure. V-shaped pull levers are pivotally connected on one side of the U-shaped tube, whereby when folding the cross tubes, the U-shaped tubes are also folded to ensure safety and more reliably support the crib structure at multiple points of the bottom thereof.
