Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] In this embodiment, if Figure 1-2 As shown, the utility model provides a foldable turnover box, including a base frame 1, a bottom plate 11 is provided on the top of the base frame, shafts 12 are provided at both ends of the bottom plate, a flap 2 is connected to the bottom plate through the shafts, corner posts 3 are provided on the four corners of the bottom plate, slots 31 are provided on the tops of the corner posts, a slide groove 32 is provided in the middle of the corner posts, and the tops of the corner posts are connected to the folding frame 4;

[0027] The folding frame includes an outer vertical rod 41, a horizontal rod 42 and an inner vertical rod 43. The bottom of the outer vertical rod is connected with a bolt 411, which is installed on the slide groove. The lower part of the outer vertical rod is provided with a protrusion 412, and the lower end of the protrusion matches the slot. When the lower end of the protrusion is in contact with the slot, the folding frame cannot be folded.

[0028] In this embodiment, it is further configured that the outer diameter of the bolt head is larger than the width of the slide slot, the bolt head is located outside the slide slot, the outer diameter of the bolt tail is slightly smaller than the width of the slide slot, the bolt tail passes through the slide slot and is connected to the outer vertical rod, the bolt can move in the slide slot along the vertical direction, and because the outer diameter of the bolt head is larger than the width of the slide slot, the outer vertical rod and the corner column will not separate.

[0029] In this embodiment, a locking block 413 is provided in the middle of the outer vertical rod, a top seat 414 is provided at the top of the outer vertical rod, and a chamfer is provided at the top of the top seat to avoid scratches. The top seat can be made of metal or rubber, and can be used as a buffer when folded to avoid damage.

[0030] In this embodiment, it is further configured that a reinforcing rib 21 is provided on the back side of the flap.

[0031] In this embodiment, a latch component 22 is further arranged on both sides of the back of the flap away from the bottom plate, and the latch component cooperates with the locking block for locking. There are at least four sets of latch components and locking blocks. If the locking function needs to be strengthened, another latch component can be arranged on both sides of the back of the flap close to the bottom plate, and correspondingly, the outer vertical rod is provided with a locking block.

[0032] In this embodiment, a handle hole 23 is further arranged in the middle of one end of the flap away from the bottom plate, and the handle hole is convenient for pulling the flap.

[0033] In this embodiment, it is further configured that the crossbars are provided with connecting pieces 421 at the same intervals, and the connecting pieces corresponding to the two folding frames are connected to the two ends of the dividing rod to separate the gas cylinders to avoid collision of the gas cylinders.

[0034] In this embodiment, when the road condition is poor and bumps are likely to occur, causing the gas cylinders to collide, it is necessary to install a partition bar. The specific process is to first install the middle partition bar, and the two ends of the partition bar are connected to the cross bars on the two folding frames by bolts. The operator moves one gas cylinder into the turnover box, and then installs the outer layer of partition bars. The operator moves another gas cylinder into the turnover box, and then installs the outer layer of partition bars to fix it.

[0035] In this embodiment, a base 33 is further provided at the bottom of the corner column, and a square groove is provided at the bottom of the base, and the size of the square groove is consistent with the cross-section of the top of the corner column.

[0036] Embodiment 2:

[0037] In this embodiment, if Figure 1-3 As shown, a base is provided at the bottom of the corner column, and a square groove is provided at the bottom of the base, and the size of the square groove is consistent with the cross-section of the top of the corner column. When stacking is required, the four corner bases of a folded turnover box are stacked on the top of the corner column below, and stacked in sequence, which can save a lot of space and prevent the bottom of the turnover box from contacting rain in bad weather.

[0038] The operating principle of the foldable turnover box is as follows: when in use, the folded turnover box is transferred to the designated location on the bottom frame by the forklift fork, the two folding frames are folded so that the folding frames are set vertically, the folding frames are pressed down, the bolts move downward in the slide slots until the lower ends of the protrusions match and lock with the corner column slots, at which time the folding frames cannot be folded, the two flaps are folded through the handle holes so that the ends of the flaps contact with the bottom surface to form a slope, the operator moves the gas cylinders into the turnover box from both ends of the flaps, and after the gas cylinders are moved, the flaps are flipped up and the latch components on the back of the flaps are engaged with the locking blocks, and the turnover box is transferred to the transport vehicle by the forklift.

[0039] The folding process of the foldable turnover box is to first fold the two side flaps to the upper part of the bottom plate, then lift the folding frame vertically upward so that the protrusions are separated from the slots and cannot be locked, and then fold the folding frame. When stacking is required, the four corner bases of a folded turnover box are stacked correspondingly on the top of the corner columns below, and stacked in sequence.
