[0038] As described in the background technology, a large part of the products in power materials are currently packaged in logistics turnover boxes. However, most of the existing logistics turnover boxes are packaging boxes, such as cardboard boxes, wooden boxes, iron boxes, storage cages, etc. The above ordinary packaging boxes cannot be compressed or folded. During use, the single unit occupies a large space, and it is not convenient to stack with a forklift. It is easy to overturn when moving with a forklift, which poses a great safety hazard, and cannot be recycled and reused, resulting in high logistics and transportation costs, inconvenience in use, and easy to generate a large amount of packaging waste, resulting in a large amount of resource waste, which is not conducive to actual use; even if some logistics turnover boxes can be folded, there are problems of complex structure and high processing cost, resulting in poor general performance and low safety performance.

[0039] To this end, the present application provides a logistics turnover box that is easy to fold and can be repeatedly recycled, which is used to package materials to facilitate the overall handling and turnover transportation of the materials.

[0040] The following uses a logistics turnover box used to pack power materials when transporting power materials as an example to illustrate the structure of the logistics turnover box in this application. It can be understood that in other embodiments, the logistics turnover box of this application is not limited to packing power materials, but can also be used to pack any other type of materials, which is not limited here.

[0041] Refer to Figures 1 and 2, which show schematic diagrams of a logistics turnover box 10 in an embodiment of the present application when it is in an unfolded state. The logistics turnover box 10 provided in an embodiment of the present application includes a main body 100 and an upper cover 200 that are connected to each other, wherein the main body 100 is a foldable structure. When materials need to be packaged, the main body 100 can be unfolded to form a receiving space 101 for accommodating materials, and the upper cover 200 can close the receiving space 101 to protect the materials; when the materials do not need to be packaged, the main body 100 can be folded and contracted to reduce the occupied space in the vertical direction, thereby facilitating transportation and recycling.

[0042] Specifically, see Figures 1 to Figure 3 In one embodiment, the main body 100 includes a base 110, a plurality of columns 120 and a drawstring 130, wherein the base 110 serves as a load-bearing platform for carrying materials, a plurality of columns 120 are arranged on the base 110 at intervals along the circumference of the base 110, and are rotatably connected to the base 110 so as to be able to stand upright relative to the base 110 or lie flat on the base 110, and the drawstring 130 is connected to one of the columns 120 and is made of a soft material (such as cloth or plastic film material), so that the drawstring 130 can be wrapped around all the columns 120 when the columns 120 are erected relative to the base 110, so that the drawstring 130, the base 110 and the columns 120 together form a storage space 101 for accommodating materials, thereby being able to act as a barrier for the materials when they are carried on the base 110, and preventing the materials from slipping during transportation. Figure 4 In the embodiment shown in , when viewed from above, the base 110 is a rectangular or square structure, and there are four columns 120. The four columns 120 are arranged at the four corners of the base 110 along the circumference of the base 110. There are two drawstrings 130, and the two drawstrings 130 are arranged at intervals in the vertical direction to form a high enclosure in the vertical direction, so as to accommodate more layers of materials or larger materials.

[0043] It is understandable that the shape of the base 110 is not limited, and can be circular or any polygonal shape when viewed from above. The number of the columns 120 is not limited, and can be three or more, depending on the shape of the accommodation space 101 to be enclosed. The number of the drawstrings 130 is also not limited, and can be one drawstring 130 with a wider width in the vertical direction, or multiple drawstrings 130 with a narrower width in the vertical direction, as long as they can effectively enclose the materials.

[0044] Please continue to refer to Figures 1 and 2. The base 110 includes a load-bearing plate 111 and a plurality of feet 112 arranged on the bottom side of the load-bearing plate 111. The material of the load-bearing plate 111 can be a plastic plate or a metal plate with strong load-bearing capacity. The plurality of feet 112 are distributed in a matrix on the bottom side of the load-bearing plate 111, so that the base 110 can be formed with a plurality of holes for forklift arms to insert when placed on a plane. When transporting materials, the forklift arms can be inserted into the above-mentioned holes, so that the materials can be transported more conveniently and quickly as a whole, thereby saving transportation time and manpower.

[0045] Similarly, the upper cover 200 is a plate-shaped structure that matches the shape of the base 110, and its material can also be a metal plate or plastic material with strong load-bearing capacity. Figure 5 , from a top view, the upper cover 200 is also in a quadrilateral shape, and preferably, a plurality of foot grooves 201 arranged in a matrix and corresponding to the arrangement of the foot 112 of the base 110 are opened on the upper side of the upper cover 200, and each foot groove 201 is used for inserting the foot 112 of another logistics turnover box 10, so that more than two logistics turnover boxes 10 can be stacked and fixed to each other to prevent tipping during transportation. More preferably, refer to Figure 6 A plurality of limiting holes 202 are provided on the lower side of the upper cover 200, and the number and positions of the limiting holes 202 correspond to the number and positions of the columns 120. In the present embodiment, there are four limiting holes 202, which are provided at the four corners of the lower side of the upper cover 200. The top end of each column 120 can be plugged into a corresponding limiting hole 202, so that the column 120 can be limited and the four columns 120 can be evenly stressed, so that the upper cover 200 can be fixedly connected to the column 120 and close the opening of the accommodating space 101.

[0046] It is worth noting that the logistics turnover box 10 provided in the present application may not be provided with an upper cover 200, but a hole may be opened on the bottom side of the foot 112. When multiple logistics turnover boxes 10 are stacked in the vertical direction, the end of the column 120 of one of the material turnover boxes away from the base 110 is inserted into the hole opened in the foot 112 of another material turnover box. This is not limited here, but it is obvious that providing an upper cover 200 can provide better protection for the materials, which is obviously the best embodiment.

[0047] For details on the connection structure between the column 120 and the base 110, see Figure 3 and Figure 4 The base 110 has a plurality of connection blocks 140 on one side (i.e., the upper side) of the base 110 for forming the accommodating space 101. Figure 3 and Figure 4 In the embodiment shown in FIG. 1 , the number of the connecting blocks 140 is four, and each column 120 is rotatably connected to the connecting block 140. Figure 7 Each connecting block 140 is provided with a U-shaped groove 140a, and one end of each column 120 away from the upper cover 200 is inserted into the U-shaped groove 140a of a corresponding connecting block 140. The side of each connecting block 140 is provided with an opening connected to the U-shaped groove 140a, and the opening is used to avoid the column 120 when the column 120 rotates relative to the connecting block 140, so that the column 120 can be placed flat on the base 110.

[0048] In one embodiment, the length of the column 120 is less than half the length of the side of the base 110, and Figure 4 In the X direction, the two spaced connection blocks 140 are open at the sides so that the columns 120 will not interfere with each other when they are flattened relative to the base 110. When the columns 120 are flattened relative to the base 110, the base 110 Figure 4 There are two columns 120 respectively placed flat on the two opposite edges in the middle Y direction; of course, in another embodiment, the opening direction of the connecting block 140 on the side can also be changed so that when the columns 120 are placed flat relative to the base 110, there is a column 120 placed flat on each of the four edges of the base 110, which is not limited here.

[0049] Further, see Figure 7 and Figure 8Each column 120 is connected to the connecting block 140 through an adjusting bolt 150, that is, the adjusting bolt 150 is simultaneously provided in the connecting block 140 and the column 120. By rotating the adjusting bolt 150, the tightness between the column 120 and the connecting block 140 can be adjusted so that the column 120 can be fixed to the connecting block 140 or can rotate relative to the connecting block 140. In this way, when it is necessary to package materials, tighten the adjusting bolt 150 so that the column 120 can stand upright relative to the base 110 without rotating at will; when the logistics turnover box 10 is idle, loosen the adjusting bolt 150 so that the column 120 can be laid flat on the base 110 to reduce the occupied space.

[0050] For further information, see Fig. 9 and Fig.10 In order to better store the drawstring 130 and make the logistics turnover box 10 look neat when idle, the column 120 connected to the drawstring 130 includes a column 121 and a reel 122. The column 121 is a hollow structure with a cavity 1221 inside, and the side of the column 121 is grooved. The reel 122 is arranged in the cavity 1221 and can rotate around its own central axis. The drawstring 130 can be retractably wound on the reel 122 so that it can pass through the groove on the side of the column 121 under the rotation of the reel 122 to be exposed in the cavity 1221 or recovered in the cavity 1221 in the form of a drawstring roll 130a.

[0051] As an optional embodiment, the reel 122 can also be fixedly set in the cavity 1221 of the column 121, and a sleeve is provided on the outer circumference of the reel 122. The sleeve is rotatably mounted on the reel 122 through a bearing, and the pull strap 130a is wound around the sleeve, that is, it is wound around the reel 122 through the sleeve, so that the pull strap 130 can be more smooth when extending and retracting, and it is more labor-saving when retracting the pull strap 130.

[0052] The drawstring 130 can be retracted by manually rotating the reel 122 or automatically rotating the reel 122. When the drawstring 130 is retracted by manually rotating the reel 122, refer to Figure 7 and Fig.10The upper end of the reel 122 is provided with a rotating handle 1222. When retracting the drawstring 130, the reel 122 can be conveniently rotated by holding the rotating handle 1222, so that the drawstring 130 can be conveniently rewound on the reel 122 to form a drawstring roll 130a and recovered in the cavity 1221 of the column 120; when the drawstring 130 is retracted by the automatic rotating reel 122, the reel 122 can be connected to a constant force spring roll. After the reel 122 rotates an angle around its own central axis to release the drawstring 130, it can automatically rotate in the opposite direction under the action of the elastic force generated by the constant force spring roll, so that the drawstring 130 is automatically rewound on the reel 122 to form a drawstring roll 130a.

[0053] It should be noted that when there are more than two drawstrings 130, all drawstrings 130 are similar to Fig.10 As shown in FIG. 1 , the two components are wound around the reel 122 at the same time and can be retracted together.

[0054] See also Figure 8 and Fig. 9 After the drawstring 130 is pulled out and wrapped around all the columns 120, in order to prevent the drawstring 130 from shifting, a drawstring limiting frame 160 is provided on the side of the column 120. The drawstring limiting frame 160 is provided with a drawstring limiting groove 161 running through the opposite sides of itself, so that the drawstring limiting frame 160 is roughly U-shaped. The drawstring limiting groove 161 is used for the drawstring 130 to pass through, so that the drawstring 130 can be limited when it is wrapped around the column 120 to prevent the drawstring 130 from shifting. Preferably, when there are multiple drawstrings 130, multiple drawstring limiting frames 160 may be provided on each column 120, and each drawstring limiting frame 160 is used for allowing a corresponding drawstring 130 to pass through so as to limit each drawstring 130. Of course, only one drawstring limiting frame 160 may be provided on each column 120, and multiple drawstrings 130 all pass through this one drawstring limiting frame 160, and there is no specific limitation.

[0055] On the basis of the above embodiment, in order to fix the drawstring 130 after it is wound around all the pillars 120, so that the drawstring 130 can always form a fence around the materials, refer to Figure 7 and Fig.11 A drawstring head 131 is provided at one end of the drawstring 130. The outer diameter of the drawstring head 131 is greater than the thickness of the drawstring 130 and greater than the width of the drawstring limiting groove 161. In this way, when the drawstring 130 is wrapped around all the columns 120, the drawstring head 131 can be clipped and fixed on the drawstring limiting frame 160 connected to the column 120, so as not to fall off the column 120.

[0056] It is understandable that a hook may be provided on the pull strap 130 and a buckle may be provided on the column 120. The pull strap 130 may be fixed to the column 120 by engaging the hook with the buckle of the column 120. There is no special limitation here.

[0057] In addition, in order to enable users to grasp detailed information about materials and to be able to move or use the materials in a timely manner, an electronic information device (not shown in the figure), a clock chip (not shown in the figure) and an alarm device (not shown in the figure) are provided on the base 110. The clock chip is electrically connected to the electronic information device, and the alarm device is electrically connected to the clock chip. The electronic information device is used to record information about the materials placed in the accommodating space 101, such as product name, packing quantity, production date, and expiration date, etc. The user can update the above information through a handheld device using NFC short-range communication technology. At the same time, the clock chip is used to monitor the expiration date of the materials, and the alarm device is used to prompt an alarm (such as flashing or sounding an alarm, etc.) when the expiration date of the materials is approaching, so as to remind the user to arrange for the products with approaching expiration dates to be put into use as soon as possible to avoid product scrapping due to expiration.

[0058] The following is combined with Figures 1 to Fig.11 , and then introduce the installation process of the logistics turnover box 10:

[0059] When it is necessary to package the materials, first, erect the column 120 relative to the base 110, tighten the adjusting bolt 150 to fix the column 120 relative to the connecting block 140; then pull out the drawstring 130, so that the drawstring 130 is wrapped around all the columns 120 and passes through the drawstring limiting groove 161 of the drawstring limiting frame 160; then, clamp and fix the drawstring head 131 on the drawstring limiting frame 160 connected to the column 120, thereby completing the installation of the logistics turnover box 10.

[0060] When the logistics turnover box 10 is idle, first retract the draw strap 130, so that the draw strap roll 130a is wound around the reel 122 and accommodated in the cavity 1221 of the column 120; then loosen the adjusting bolt 150 to allow the column 120 to rotate relative to the connecting block 140, and place the column 120 flat on the column 120, so that the logistics turnover box 10 can be easily received and stored, reducing the storage space occupied, and when the logistics turnover box 10 is recycled, a truck or container truck can transport more logistics turnover boxes 10 at a time.

[0061] It can be seen that the logistics turnover box provided in the present application, by being set as the above-mentioned foldable structure, is not only simple in structure and highly versatile, but also easy to install. Compared with traditional packaging boxes such as cardboard boxes, wooden boxes, iron boxes, and storage cages, it has the characteristics of high load-bearing capacity, foldability, waterproof and dustproof, and recyclability. It will not generate any packaging waste, greatly reducing the packaging cost of materials.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
