[0002] Agricultural products are mainly loaded in plastic baskets or transfer boxes from the field to the retail consumption end. For most cold chain transportation links, most of the existing agricultural product logistics transfer boxes are integrated foam plastic boxes. On the one hand, the white foam boxes are not environmentally friendly. On the other hand, due to their large volume, they occupy a relatively large space, and are for single use, causing a large amount of waste and affecting sales.

[0003] In the prior art, there are also folding and reusable logistics transfer boxes for loading, and then the transfer boxes are folded and recycled. However, the existing folding transfer boxes generally arrange the box body and the box cover separately. For example, the patent with the Chinese publication number CN218259247U discloses "a foldable agricultural product logistics transfer box", which includes a bottom plate and side plates installed on the sides of the bottom plate. The side plates and the bottom plate form a box body, and a box cover is arranged on the top of the box body.

[0035] In view of the deficiencies of the prior art, this embodiment provides a reusable folding transfer box, which can be specifically referred to as follows:

[0036] As shown in the attached Figure 1 and attached Figure 4As shown in the figure, a reusable folding transfer box includes a bottom plate 1, two short plates 2, two long plates 3, a first cover plate 4, a second cover plate 5, and a double-rotating shaft connector 6. Short plates 2 are rotatably arranged at both lateral ends of the bottom plate 1. The two short plates 2 can rotate towards the center of the bottom plate 1, so that the side walls of the two short plates 2 are in contact with the surface of the bottom plate 1, being in a folded state. And a limiting device is arranged on the two short plates 2, so that when the two short plates 2 rotate in the opposite directions, they can only be in a state where the short plates 2 are perpendicular to the long plates 3; Long plates 3 are rotatably arranged at both longitudinal ends of the bottom plate 1. The two long plates 3 can also rotate towards the center of the bottom plate 1. When the two long plates 3 are in the open state, they are perpendicular to the surface of the bottom plate 1; The two short plates 2 and the two long plates 3 cooperate with the bottom plate 1 to enclose a cavity with an upward opening. The cavity is used to place agricultural products. And the rotation center of the short plates 2 is lower than the rotation center of the long plates 3. Thus, after the short plates 2 are folded, the long plates 3 can be folded and placed on the top of the short plates 2 to improve the folding efficiency. First cover plate 4 and second cover plate 5 are respectively rotatably arranged on the two long plates 3. A first rotation groove 33 is formed on the side of the long plate 3 away from the bottom plate 1. Second rotation grooves 7 are formed on the first cover plate 4 and the second cover plate 5. The first rotation groove 33 corresponds to the second rotation groove 7 and is connected by a double-rotating shaft connector 6, that is, one end of the double-rotating shaft connector 6 is connected to the first rotation groove 33, and the other end is connected to the second rotation groove 7. Thus, the first cover plate 4 and the second cover plate 5 can rotate around the top of the long plate 3 to cover and open the opening of the cavity, or be placed on one side of the long plate 3.

[0037] As shown in the attached Figure 6 figure, in the initial state, the transfer box is in a folded state. When in use, the first cover plate 4 and the second cover plate 5 can be lifted first. At the same time, the two long plates 3 are rotated and are perpendicular to the surface of the bottom plate 1. Then the two short plates 2 are rotated and are perpendicular to the surface of the bottom plate 1. At this time, the two short plates 2, the two long plates 3, and the bottom plate 1 enclose a cavity with an upward opening, which can be used to place agricultural products. And the first cover plate 4 and the second cover plate 5 can be placed on one side of the two long plates 3 and are parallel to the long plates 3 to prevent damage to the first cover plate 4 and the second cover plate 5 during the process of loading agricultural products; Through the above device, the first cover plate 4 and the second cover plate 5 can be respectively connected to the corresponding long plates 3. When loading or unloading goods, the first cover plate 4 and the second cover plate 5 do not need to be removed, thus preventing the loss of the first cover plate 4 and the second cover plate 5; At the same time, through the double-rotating shaft connector 6, the first cover plate 4 and the second cover plate 5 can be rotated to the side walls of the long plates 3, effectively preventing damage.

[0038] In this embodiment, as shown in the attached Figure 3As shown, the bottom inner side of the short board 2 is provided with a rounded corner to facilitate the short board 2 to rotate toward the center of the bottom board 1 and to provide shielding. The bottom outer side of the short board 2 is not provided with a rounded corner, so that when the short board 2 is rotated, it can only rotate 90 degrees, that is, the short board 2 and the surface of the bottom board 1 are in a vertical state; the bottom inner side of the long board 3 is provided with a rounded corner, and the bottom outer side of the long board 3 is not provided with a rounded corner, which also makes the long board 3 only able to rotate 90 degrees; the inner side of the part of the bottom board 1 that is rotatably connected to the short board 2 and the long board 3 Rounded corners are provided to facilitate the rotation of the long board 3 and the short board 2; the first cover plate 4 and the second cover plate 5 are provided with rounded corners at one end close to the long board 3 to facilitate the first cover plate 4 and the second cover plate 5 to rotate to the top of the long board 3 and be in a vertical state with the long board 3 to block the opening, and the first cover plate 4 and the second cover plate 5 are located on the outside of the long board 3 and are in a parallel state with the long board 3. The top of the long board 3 can be rounded as needed to cooperate with the rotation of the first cover plate 4 and the second cover plate 5.

[0039] In one embodiment of the present application, as shown in the attached Figure 5 As shown, both ends of the double rotating shaft connecting member 6 are arc-shaped to facilitate the cooperation with the first rotating groove 33 and the second rotating groove 7, and the width of the double rotating shaft connecting member 6 is the same as the sum of the heights of the first rotating groove 33 and the second rotating groove 7 to avoid the formation of gaps between the long plate 3 and the first cover plate 4 and the second cover plate 5, so as to fail to better cover the opening of the cavity.

[0040] In one embodiment of the present application, as shown in the attached Figure 1 As shown, a first card slot 41 is provided on the top of the first cover plate 4, and a first card block 51 is provided on the bottom of the second cover plate 5. When the first cover plate 4 and the second cover plate 5 are both in the opening of the shielding cavity, the two are in a parallel state. At this time, the first card block 51 cooperates with the first card slot 41, so as to cooperate with the first cover plate 4 and the second cover plate 5 and connect them, thereby improving the overall stability, airtightness and thermal insulation of the transfer box, and also facilitating the moving and transportation of the transfer box.

[0041] In this embodiment, the first card slot 41 is located at the top of the first cover plate 4 and is set upward. The first card block 51 is set at the top of the second cover plate 5. When the first cover plate 4 and the second cover plate 5 block the cavity opening, the first cover plate 4 abuts against the second cover plate 5, and the first card block 51 falls into the first card slot 41; a first magnet block is set in the first card slot 41, and a second magnet block is set inside the second card block 31. When the first card slot 41 cooperates with the first card block 51, the first magnet block and the second magnet block attract each other to prevent the first cover plate 4 and the second cover plate 5 from shaking, which causes the first card block 51 to detach from the first card slot 41.

[0042] In this embodiment, third magnet blocks may be provided on the opposite sides of the two long plates 3. When packing, the first cover plate 4 and the second cover plate 5 rotate to the opposite sides of the two long plates 3, and the first cover plate 4 and the second cover plate 5 can be abutted against the corresponding long plates 3 through the third magnet blocks, so as to prevent the first cover plate 4 and the second cover plate 5 from shaking or colliding when the transfer box moves, resulting in damage to the first cover plate 4 and the second cover plate 5.

[0043] In one embodiment of the present application, as shown in the attached Figure 3 and the attached Figure 4 As shown, second card slots 21 are provided at both ends of the opposite sides of the two short plates 2, and second card blocks 31 are provided at both ends of the opposite sides of the long plates 3. The second card blocks 31 cooperate with the second card slots 21 to connect the short plates 2 and the long plates 3, which can not only limit the rotation angle of the short plates 2, but also increase the overall stability of the transfer box.

[0044] In this embodiment, a T-shaped convex block 22 is provided on the side wall of the second card slot 21, and a T-shaped groove 32 is provided on the side wall of the second card block 31. The T-shaped groove 32 cooperates with the T-shaped convex block 22 to fix the short plate 2 and the long plate 3. Through the mortise and tenon structure of the T-shaped convex block 22 and the T-shaped groove 32, the stability between the short plate 2 and the long plate 3 can be further improved.

[0045] In one embodiment of the present application, as shown in the attached Figure 2 As shown, third rotation grooves 11 are provided on the transverse sides of the bottom plate 1, and the transverse sides of the bottom plate 1 are provided with rounded corners. The bottom wall of the third rotation groove 11 is flush with the surface of the bottom plate 1. A first rotation block 24 is provided at the bottom of the short plate 2, and a rounded corner is provided on the inner side of the bottom of the first rotation block 24. The first rotation block 24 is rotationally matched with the third rotation groove 11 to enable the short plate 2 to rotate with the bottom plate 1; at the same time, the bottom wall of the first rotation block 24 abuts against the surface of the bottom plate 1.

[0046] In this embodiment, the distance between the opposite sides of the two short plates 2 is less than the transverse length of the bottom plate 1, that is, there is a certain distance between the side wall of the short plate 2 and the side wall of the bottom plate 1, and the distance between the rotation axis of the first rotation block 24 and the surface of the bottom plate 1 is less than the distance between the rotation axis of the first rotation block 24 and the side wall of the bottom plate 1; through the distance between the side wall of the short plate 2 and the side wall of the bottom plate 1, and the distance misalignment difference after the first rotation block 24 rotates, there will be a certain distance between the opposite sides of the two short plates 2 and the side wall of the bottom plate 1 after the short plate 2 rotates. When the long plate 3 is folded, the second card block 31 on the long plate 3 can wrap the short plate 2 to protect the short plate 2; at the same time, the folding ratio of the transfer box can also be improved through the wrapped folding.

[0047] In one embodiment of the present application, as shown in the attached Figure 2As shown, a support block 12 is provided on the top of the bottom plate 1. A fourth rotation groove 13 is formed in the support block 12, and a rounded corner is provided on the inner side of the support block 12. A second rotation block 34 is provided at the bottom of the long plate 3, and a rounded corner is provided on the inner bottom side of the second rotation block 34. The second rotation block 34 is rotationally engaged with the fourth rotation groove 13. When the long plate 3 rotates, the bottom of the long plate 3 will abut against the inner side wall of the support block 12 to facilitate abutting against the long plate 3. The first cover plate 4 and the second cover plate 5 are folded and placed on the top of the long plate 3 through a double-rotation shaft connecting member 6.

The two buckle grooves 9 of the first cover plate 4 and the second cover plate 5 correspond one by one, and the corresponding two buckle grooves 9 are engaged with the buckles 8. The first cover plate 4, the second cover plate 5 and the short plates 2 can be fixed through the buckles 8 to improve the overall stability and prevent the first cover plate 4 and the second cover plate 5 from detaching from the opening of the cavity.

[0049] In this embodiment, as shown in the attached Figure 4 figure, two placement grooves 35 are provided on both sides of the two long plates 3 facing each other. The placement grooves 35 of the two long plates 3 correspond to each other, and the corresponding two placement grooves 35 are engaged with the buckles 8 for accommodating the buckles 8 to prevent the buckles 8 from abutting against the side wall of the long plate 3, resulting in the inability to fold the long plate 3.

[0050] In an embodiment of the present application, finger grooves 23 are provided on the opposite sides of the two short plates 2. The finger grooves 23 are located at the bottom of the buckles 8 to facilitate the staff to place their fingers for handling.
