[0002] See Figure 1 Generally, existing bed frame devices, whether for online sales or user self-delivery, can be folded to reduce overall volume, which improves the convenience of transportation and reduces transportation costs. In addition, when transported to the place of use, the bed frame can be used immediately by unfolding it without complicated assembly and programming, which can also increase the user's willingness to buy. For example, the foldable bed frame disclosed in Chinese Utility Model Patent Publication No. CN213882572U has a pivot structure 11 including two sub-plates 111 disposed on the front bed frame and the rear bed frame, a main plate 112 pivotally connected to the sub-plates 111, and two limiting pins 113 disposed on the main plate 112.
