Detailed implementation manners

[0023] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of the various structures described in the following implementation manners are merely examples, and the present utility model is not limited to the various structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Refer to Figures 1 - 5, the present utility model provides a folding turnover box, which includes a base 1. Two third side plates 4 are rotatably connected between the inner walls on both sides of the base 1, and the two third side plates 4 are symmetrically distributed. First side plates 2 are rotatably connected to both sides of the base 1. One ends of the two first side plates 2 are rotatably connected to a second side plate 3 through a shaft. The height of the first side plate 2 and the second side plate 3 after unfolding is flush with the height of the third side plate 4. Locking mechanisms for fixing the unfolded second side plate 3 and the third side plate 4 are provided at both ends of the two second side plates 3. Limiting mechanisms for limiting the angle between the unfolded first side plate 2 and the second side plate 3 are provided on one side of the two first side plates 2. Fixing components for resisting the folded second side plate 3 are provided on one side of the two third side plates 4. During use, unlock the fixing of the second side plate 3 by the fixing component, rotate the first side plate 2 and the second side plate 3 to make the first side plate 2 perpendicular to the base 1 and make the first side plate 2 and the second side plate 3 on the same horizontal line, and use the limiting mechanism to fix the first side plate 2 and the second side plate 3. Then rotate the third side plate 4 to make the third side plate 4 perpendicular to the base 1, and then use the locking mechanism to fix the unfolded third side plate 4 and the second side plate 3, thereby forming a box structure for placing items. The first side plate 2, the second side plate 3 and the third side plate 4 are not separated from the base 1. When transporting, fold the first side plate 2, the second side plate 3 and the third side plate 4, occupying less space, and there is no need to package them separately, reducing the packaging cost of transportation. Moreover, the structure is simple, the assembly is fast, and the requirement for the experience of assembly workers is low.

[0025] In the present utility model, the locking mechanism includes a rotating frame 14. One end of the rotating frame 14 is in the shape of a mushroom head, and the other end is in a ring shape. The rotating frame 14 is rotatably connected to one side of the second side plate 3. First card slots 13 are opened on the same side at both ends of the two third side plates 4. After the second side plate 3 and the third side plate 4 are unfolded and in contact, rotate the rotating frame 14 to make the mushroom head-shaped end of the rotating frame 14 snap into the first card slot 13 to fix the unfolded second side plate 3 and the third side plate 4, making the entire side plate of the turnover box stable, thereby improving the stability of the turnover box after unfolding.

[0026] Among them, the limiting mechanism includes two rotating grooves 8, both of which are opened on one side of the first side plate 2. The inner walls of one side of the two rotating grooves 8 are rotatably connected to clamping rods 11 through bolts. Two positioning grooves 12 are opened on one side of each of the two second side plates 3. Rubber blocks 9 are provided at both ends of the multiple clamping rods 11. After the first side plate 2 and the second side plate 3 are unfolded, rotate the clamping rods 11 to make one end of the clamping rods 11 snap into the positioning grooves 12, so that the first side plate 2 and the second side plate 3 do not rotate relative to each other, thereby keeping the first side plate 2 and the second side plate 3 on the same horizontal line. When one end of the clamping rod 11 snaps into the positioning groove 12, the fixing effect of the unfolded turnover box is improved. The rubber blocks 9 are also located in the positioning grooves 12 to assist in fixing the clamping rods 11, further improving the fixing stability between the first side plate 2 and the second side plate 3. When the first side plate 2 and the second side plate 3 are folded, the clamping rods 11 are completely located in the rotating grooves 8.

[0027] Among them, the fixing component includes a placement groove 6, which is opened on one side of the third side plate 4. A rotating block 7 is rotatably connected between the inner walls of both sides of the placement groove 6. Two symmetrically distributed mounting grooves 17 are opened at one end of the rotating block 7. A baffle 16 is rotatably connected in each of the two mounting grooves 17. A blocking component for fixing the position of the baffle 16 is provided at one end of the rotating block 7. After the turnover box is folded, rotate the rotating block 7 to take out one end of the rotating block 7 from the placement groove 6, and then rotate the two baffles 16 so that the two baffles 16 are respectively in contact with the second side plates 3 on both sides, and use the blocking component to fix the baffles 16, thereby completing the fixation of the folded second side plates 3, and further completing the fixation of all the parts of the folded turnover box. The blocking component is preferably a limiting plate 18, and the limiting plate 18 is rotatably connected to one end of the rotating block 7 through bolts, and the limiting plate 18 can be in contact with the baffle 16. Rotate the baffle 16 so that both ends of the baffle 16 are in contact with the baffle 16, thereby fixing the rotated baffle 16. When the turnover box is unfolded, the baffle 16 and the rotating block 7 are not in the placement groove 6.

[0028] Furthermore, second card slots 15 identical to the first card slots 13 are opened on both sides of the two first side plates 2. When the first side plate 2 and the second side plate 3 are folded, the rotating frame 14 snaps into the second card slots 15, thereby fixing the folded first side plate 2 and the second side plate 3, enabling the rotating frame 14 to have multiple functions, and further reducing the production cost of the turnover box.

[0029] Furthermore, pulling grooves 5 penetrating the third side plates 4 are opened on one side of each of the two third side plates 4. The turnover box can be easily lifted through the pulling grooves 5. Avoidance grooves 10 are opened on one side of each of the two first side plates 2, and the folded second side plates 3 are located in the avoidance grooves 10, making the folded second side plates 3 flush with the first side plates 2, thereby facilitating the stacking of the folded turnover boxes.

[0030] Working principle of the utility model: During use, rotate the limit plate 18 to disengage the two ends of the limit plate 18 from contact with the baffle 16. Then rotate the two baffles 16 to disengage the baffles 16 from contact with the second side plate 3, thereby releasing the fixation of the folding turnover box. Rotate the rotating block 7 so that the rotating block 7 and the two baffles 16 are both located in the placement groove 6. Rotate the first side plate 2 and the second side plate 3 so that the first side plate 2 is perpendicular to the base 1 and the first side plate 2 and the second side plate 3 are on the same horizontal line. Rotate the clamping rod 11 so that one end of the clamping rod 11 is inserted into the positioning groove 12, so that the first side plate 2 and the second side plate 3 no longer rotate relative to each other. Then rotate the third side plate 4 so that the third side plate 4 is perpendicular to the base 1. Rotate the rotating frame 14 so that the mushroom-shaped end of the rotating frame 14 is inserted into the first card slot 13 to fix the unfolded second side plate 3 and the third side plate 4, forming a box structure for placing items. The first side plate 2, the second side plate 3, and the third side plate 4 are not separated from the base 1. During transportation, the first side plate 2, the second side plate 3, and the third side plate 4 are folded, occupying less space and eliminating the need for separate packaging, reducing the packaging cost of transportation. Moreover, the structure is simple, the assembly is fast, and the requirements for the experience of assembly workers are low.
