Referring to fig. 9, the plug 42 is a round rod and is rotatably engaged with the plug seat 41, and a limiting rod 46 is welded to a side wall of the plug 42. The limiting rod 46 is U-shaped, and is used in cooperation with the first limiting block 43, the second limiting block 44 and the third limiting block 45, and also serves as a handle.

Referring to fig. 9, the width of the limiting rod 46 is slightly smaller than the distance between the top of the second limiting block 44 and the first limiting block 43, and is also smaller than the distance between the top of the second limiting block 44 and the third limiting block 45.

When the bolt 42 is completely separated from the pin hole 24, the operator aligns one side of the stopper rod 46 with a gap between the first stopper 43 and the second stopper 44, and then pushes one side of the stopper rod 46 into the gap between the first stopper 43 and the second stopper 44 by using the characteristic that the second stopper 44 is elastically deformable, thereby locking the bolt 42 at the gap.

When the bolt 42 penetrates the pin hole 24, an operator aligns one side of the stopper rod 46 with a gap between the second stopper 44 and the third stopper 45, and then squeezes the one side of the stopper rod 46 into the gap between the second stopper 44 and the third stopper 45 by using the characteristic that the second stopper 44 is elastically deformable, so as to lock the bolt 42 at the gap.

The implementation principle of the foldable turnover box in the embodiment of the application is as follows:

after the goods are transported, the operator pulls the latch 42 out of the pin hole 24, and then locks the latch 42 by inserting one side of the stopper rod 46 between the first stopper 43 and the second stopper 44. The operator overturns the top cover 4 to be attached to the outer side wall of the second side plate 3, then lifts the second side plate 3 and the top cover 4 until the second clamping block 31 is separated from the second clamping groove 251, and the second side plate 3 is overturned towards the middle of the turnover box. The second side panel 3 is laid flat on the panel 12 and the top cover 4 is stacked on the second side panel 3.

An operator lifts one of the first side plates 2 to enable the first clamping block 23 to be completely separated from the first clamping groove 52 and to be higher than the supporting seat 5 by a distance, then the first side plate 2 is turned towards the middle of the turnover box, and finally the first side plate 2 is stacked on the top cover 4. Repeating the above operation, another first side plate 2 is stacked on the previous first side plate 2.

Finally, the turnover box is completely folded, the turnover box under the folded state can be stacked together, and the stacking feet 54 of the upper layer turnover box are embedded into the top end of the supporting seat 5 of the lower layer turnover box.

When the turnover box needs to be used, an operator turns the upper first side plate 2 to be close to vertical, and then appropriately lifts the first side plate 2, so that the first clamping block 23 moves to the position above the supporting seat 5. The first side plate 2 is continuously turned over to be completely upright, so that the first block 23 moves to a position right above the first slot 52. Finally, the first side plate 2 is lowered, so that the first clamping block 23 is clamped into the first clamping groove 52. The operation is repeated to erect the lower first side plate 2.

The operator turns the second side plate 3 to be approximately vertical, makes the second block 31 abut against the guiding inclined plane on the clamping seat 25, then lifts the second side plate 3 appropriately, and puts down the second side plate 3 after the second block 31 slides into the second clamping groove 251.

The operator turns the top cover 4 over to face the panel 12, takes the stopper rod 46 out of between the first stopper 43 and the second stopper 44, and slides the pin 42 to make the pin 42 penetrate the pin hole 24, thereby connecting the top cover 4 with the first side plate 2. The latch 42 is rotated so that one side of the stopper rod 46 is caught between the second stopper 44 and the third stopper 45, and the latch 42 is locked therein.

Finally, the turnover boxes are completely unfolded, the turnover boxes in the unfolded state can be stacked together, and the stacking feet 54 of the upper layer turnover boxes are embedded into the stacking sleeves 26 of the lower layer turnover boxes.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
