The upper frame 41 and the lower frame 42 can be folded in half through a rotating connection part 5. On the inner side walls of the left and right frames 3 and the lower frame 42, there are placement parts 7. The placement parts 7 can be used to install the shelf 6. On the shelf 6, there are raised parts 61. At least the two sides of the raised parts 61 prop against the inner side of the rotating connection part 5 to limit the upper frame 41 and the lower frame 42 from folding inwards when the cabinet body is unfolded. In this technical solution, between the top frame 1 and the bottom frame 2, there are connected with the left and right frames 3 and the front and rear frames 4 to enclose the surrounding space of the cabinet body. The lower bottoms of the left and right frames 3 and the front and rear frames 4 are all hinged to the bottom frame 2 and can be stored. On this basis, the front and rear frames 4 themselves are also divided into an upper frame 41 and a lower frame 42, and there is a rotating connection part 5 in the middle. When folding, refer to the specification Figure 3 , the upper frame 41 and the lower frame 42 can be rotated inwards through the rotating connection part 5 for storage.
