[0024] like Figures 1 to 4 As shown, through the above arrangement, the frame structure in this embodiment has a foldable function. The front frame 100 and the rear frame 200 of the frame structure can be horizontally unfolded or vertically folded by rotating and assembling. After the front frame 100 and the rear frame 200 are unfolded, the unfolding lock hook 300 is engaged with the unfolding lock column 600 to keep the frame stable after unfolding. The unfolding lock hook 300 is always engaged with the unfolding lock column 600 under the action of gravity. When the frame needs to be folded, the unfolding lock hook 300 is pulled upward, and at the same time, the connecting rod 500 is connected to the unfolding lock column 600. The folding lock hook 400 is opened synchronously by the action, and when the unfolding lock hook 300 is separated from the unfolding lock column 600, the front frame 100 and the rear frame 200 can be pulled up to achieve folding.
