It includes a lower folding plate 1, a first connecting shaft 100 protruding from one side of the top of the lower folding plate 1, the top of the lower folding plate 1 is movably connected to the upper folding plate 2, the bottom two ends of the lower folding plate 1 are provided with first connecting holes 101, the top two ends of the upper folding plate 2 are provided with second connecting holes 201, the lower folding plate 1 and the upper folding plate 2 are movably connected between the bottom plate 4 and the mounting frame 5 through a fixed shaft 400, the bottom of the upper folding plate 2 is fixedly connected with a connecting piece 200, the top of the upper folding plate 2 is provided with a mounting frame 5, the two ends of the mounting frame 5 are provided with third connecting holes 600, and the inside of the third connecting hole 600 is movably connected to the side plate 3 The bottom of the side panel 3 is provided with a sliding groove 301, and the second connecting shaft 300 is raised on both sides of the top of the side panel 3. The third connecting shaft 302 is fixedly connected to the inner side of the sliding groove 301, and the outer side of the third connecting shaft 302 is sleeved with an extrusion plate 8. A groove is provided on the side of the sliding groove 301, and a buckle 7 is slidably connected inside. The buckle 7 is used to be clamped to the inside of the fixed shaft 400 when the side panel 3 is unfolded. The extrusion plate 8 is used to rotate downward under the fixed action of the third connecting shaft 302, and rest against the top of the buckle 7 to prevent the buckle 7 from detaching from the inside of the fixed shaft 400. The side panel 3 is used to support the unfolding of the lower folding panel 1 and the upper folding panel 2 after unfolding.

[0020] See also Figure 1-4 The bottom of the lower folding plate 1 and the side plate 3 are sleeved with a bottom plate 4, and the inner walls of the bottom plate 4 and the mounting frame 5 are protruding with a fixed shaft 400. The fixed shaft 400 is used to fix the lower folding plate 1 and the upper folding plate 2. Slots 401 are provided at both ends of the bottom of the bottom plate 4. The fixed shaft 400 is embedded in the first connecting hole 101 and the second connecting hole 201, and the second connecting shaft 300 is embedded in the third connecting hole 600, so that the side plate 3 can rotate around the side plate 3 for easy storage or unfolding. The top side of the mounting frame 5 is rotatably connected to the top cover 6. The lower folding plate 1 and the upper folding plate 2 are connected by a connecting piece 200 sleeved on the outside of the first connecting shaft 100. The bottom of the extrusion plate 8 protrudes to both ends and presses against the top of the buckle 7, and the buckle 7 is vertically embedded in the inside of the slot 401.

[0021] When in use, through the sliding groove 301 opened at the bottom of the side panel 3, when the side panel 3 is against the bottom of the inner cavity of the bottom panel 4, the buckle 7 is downwardly embedded into the inside of the fixed shaft 400 to fix the side panel 3. Since the extrusion plate 8 arranged above the buckle 7 can be flipped down around the third connecting shaft 302 and press against the top of the buckle 7, it prevents the buckle 7 from being separated from the inside of the fixed shaft 400, the side of the turnover box can be fixed when unfolded, making the structure of the box more stable. Due to the connection structure of the lower folding plate 1 and the upper folding plate 2, when the side panel 3 is flipped to the bottom of the mounting frame 5 for storage, the lower folding plate 1 and the upper folding plate 2 are folded to a parallel state around the first connecting shaft 100 and the connecting piece 200 connected to the top and bottom as the center of the circle, the storage box can be compressed, which can save the space occupied when the box is empty.
