[0029] like Figures 1 to 4 As shown, in this embodiment, one end of the middle box 20 is rotatably connected to one end of the bottom box 10, and the middle box 20 is used to cover the bottom box 10. One end of the cover plate 30 is rotatably connected to the middle box 20, and the cover plate 30 is used to cover the middle box 20. Optionally, the bottom of the middle box 20 is provided with a receiving cavity 201 to receive the edge of the bottom box 10. Further, the middle box 20 is also provided with a groove (not shown in the figure).
[0030] Please check again. Figures 1 to 4 The cover plate 30 includes a panel 31 and a protruding edge 32. The panel 31 is recessed and has a groove 311. The protruding edge 32 is arranged along the periphery of the panel 31 and has a relief groove 321. The protruding edge 32 facilitates the flipping of the cover plate 30. The cover plate 30 also includes a mounting base 33 for connecting the panel 31.
[0031] like Figure 1As shown, the locking assembly 40 includes a fixing block 41, a flipping block 42, and a roller 43. The fixing block 41 is installed on one side of the base box 10. One end of the flipping block 42 is rotatably connected to the fixing block 41, and the roller 43 is rotatably connected to the end of the flipping block 42 away from the fixing block 41. The roller 43 is used to engage the cover plate 30. Optionally, a slot 311 is used to accommodate the roller 43; a clearance slot 321 is used to accommodate the flipping block 42. Further, the flipping block 42 includes a first horizontal bar portion 421, a first vertical bar portion 422, a first connecting rod portion 423, a second horizontal bar portion 424, a second connecting rod portion 425, and a second vertical bar portion 426 connected end to end in sequence. The first horizontal bar portion 421 is rotatably connected to the fixing block 41, and the roller 43 is rotatably connected to the second horizontal bar portion 424. Furthermore, the first vertical rod portion 422 and the second vertical rod portion 426 have the same height, and the height of the first vertical rod portion 422 is greater than the sum of the heights of the middle box 20 and the cover plate 30.
[0032] like Figure 2 As shown, the multi-layer storage box 100 also includes a hinge 50, one end of which is installed on the side of the bottom box 10 away from the fixing block 41, and the other end is installed on the side of the middle box 20; the hinge 50 is used to cover or open the bottom box 10.
[0033] like Figure 4 As shown, the multi-layer storage iron box 100 also includes a rotating shaft 60, which passes through the mounting base 33; a groove is used to accommodate the rotating shaft 60; the cover plate 30 rotates around the rotating shaft 60 to close or open the middle box 20.

[0035] In one embodiment, the bottom box 10, the middle box 20, and the cover plate 30 are all made of iron, and the structure is sturdy.
[0036] When the multi-layer storage box 100 needs to be closed, flip the middle box 20 so that it covers the bottom box 10, with the edge of the bottom box 10 abutting the bottom of the middle box 20. At this time, the edge of the bottom box 10 is accommodated in the receiving cavity 201, so that the middle box 20 is stacked flat on the bottom box 10. Next, flip the cover plate 30 so that it covers the middle box 20 until the fastening part 322 engages with the limiting block 70. Finally, rotate the flipping block 42 around the fixing block 41 so that the roller 43 engages with the cover plate 30. At this time, the roller 43 is accommodated in the slot 311, and the first vertical rod part 422 and the second vertical rod part 426 are accommodated in the relief slot 321. The bottom box 10, the middle box 20 and the cover plate 30 are fixed by the cooperation of the roller 43 and the flipping block 42, which is convenient to use.
[0037] When it needs to be opened, rotate the flipping block 42 around the fixed block 41 to disengage the roller 43 from the slot 311, and then flip the middle box 20 to open the bottom box 10. At this time, the cover plate 30 is still closed to the middle box 20. When it needs to be opened, flip the cover plate 30 until the fastening part 322 disengages from the limiting block 70, so that the cover plate 30 is disengaged from the middle box 20.
[0038] The multi-layer storage iron box 100 of this utility model is rotatably connected to one end of the bottom box 10 via a middle box 20, and one end of the cover plate 30 is rotatably connected to the middle box 20. A fixing block 41 is installed on the bottom box 10, and one end of the flipping block 42 is rotatably connected to the fixing block 41. A roller 43 is rotatably connected to the flipping block 42. The roller 43 is used to engage the cover plate 30. By simply rotating the flipping block 42, the roller 43 can engage the cover plate 30, thus closing the bottom box 10, the middle box 20, and the cover plate 30, making it convenient to use.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
