DETAILED DESCRIPTION

[0016] In order to clearly illustrate the technical features of the scheme, the utility model is described in detail below through specific implementation modes and in combination with the accompanying drawings.

[0017] As Figs. 1-3As shown, a kind of folding turnover box, including square bottom plate 1, two short side frames 3 and two long side frames 4 are connected with the rotation shaft 2 of the four edges of square bottom plate 1 respectively, two short side frames 3 are supported between two long side frames 4, the position of square bottom plate 1 is provided with the limiting plate 5 for preventing the everted long side frame 4, the both sides of long side frame 4 are provided with the limiting plate 6 for preventing the everted short side frame 3, the movable plate 7 that can move up and down is installed in short side frame 3, movable plate 7 and short side frame 3 are elastically connected, the both ends of movable plate 7 are provided with the boss 8, the side of short side frame 3 is provided with the notch 9 corresponding the position of boss 8, the side of long side frame 4 is provided with the stop 10 corresponding the position of notch 9.

[0018] The height of rotation shaft 2 between long side frame 4 and square bottom plate 1 is higher than the height of rotation shaft 2 between short side frame 3 and square bottom plate 1, short side frame 3 is folded first when folding, then long side frame 4 is folded on short side frame 3.

[0019] Two hooks 11 are provided on short side frame 3, the position corresponding each hook 11 of movable plate 7 is provided with the elastic hanging plate 12 respectively, elastic hanging plate 12 is hung with hook 11, when staff exerts force to movable plate 7 downwards, movable plate 7 can move downwards, when releasing movable plate 7, movable plate 7 can automatically move upwards and reset under the action of elastic hanging plate 12.
