Abstract: A quickly foldable crib frame relates to the field of cribs and includes a first U-shaped surrounding frame, a second U-shaped surrounding frame, upper vertical rods, and lower vertical rods. Both two free ends of the first U-shaped surrounding frame and two free ends of the second U-shaped surrounding frame are rotatably connected to first ends of the upper vertical rods. second ends of the upper vertical rods are slidably fitted in the lower vertical rods in length directions of the lower vertical rods. After the quickly foldable crib frame is folded, the quickly foldable crib frame takes up less space and is convenient to be moved.
