    Patent number: 11484116
    Abstract: A foldable cabinet framework includes two side frames, a first beam body, and a second beam body, where two opposite ends of each of the first and second beam bodies are respectively connected to the two side frames. The first beam body and the second beam body each include a hinged part, and when the first beam body and the second beam body are in a straight state, the first beam body and the second beam body are supported between the two side frames, so that the two side frames are spaced apart and symmetrically disposed. The first beam body and the second beam body enclose a framework of a three-dimensional structure. The first beam body and the second beam body are folded by using the hinged part; and after the first beam body and the second beam body are folded, the two side frames are superposed with each other.
