It can be seen from the above description of the present invention, compared to the prior art, the present invention has the following advantages. The present invention has a novel structure and a clever design. When in use, the first rotating rod and the second rotating rod in the folded state rotate upward. While the first rotating rod and the second rotating rod are rotating upward, the first left rotating portion and the first right rotating portion are driven to rotate by the second left rotating portion and the second right rotating portion respectively. Accordingly, the first support rod and the second support rod are driven to unfold leftward and rightward respectively. When the second left rotating portion, the first left rotating portion, the second right rotating portion, and the first right rotating portion rotate in position, the second left rotating portion and the first left rotating portion snap in the left snap-in portion. Also, the second right rotating portion and the first right rotating portion snap in the right snap-in portion. Accordingly, the first rotating rod, the second rotating rod, the first support rod, and the second support rod are unfolded and fixed to form a bed frame. Then, the bedrail made of cloth can be installed, such that a baby bed is ready for use. When the bed frame is to be stored up, the left snap-in portion and the right snap-in portion are drawn back, such that the first left rotating portion and the second left rotating portion are separated from the left snap-in portion. Also, the first right rotating portion and the second right rotating portion are separated from the right snap-in portion. At this point, the first rotating rod and the second rotating rod can rotate to be folded downward. At the same time, the first left rotating portion and the first rotating portion is driven to rotate by the second left rotating portion and the second rotating portion, such that the first support rod and the second support rod close up. The present invention can realize the rapid unfolding and folding of the baby bed frame. The present invention is easy to use and operate. After purchase, it is unnecessary to assemble the baby bed frame by the user. Moreover, the present invention is easy to carry and move.
