[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Please also read Figure 1 , Figure 5 and Figure 6 , the packaging structure provided in the embodiment of the present application is now described. The packaging structure is mainly used to package the secondary protection screen cabinet 2000 so that the secondary protection screen cabinet 2000 can be effectively protected when transported in mountainous areas, plateaus and some forest areas. This embodiment is described by taking the packaging of the secondary protection screen cabinet 2000 as an example. It can be understood that in other embodiments of the present application, the above packaging structure can also be used to package and transport other products, such as electrical cabinets, refrigerators, washing machines and other equipment, which is not the only limitation here.

[0032] Please also read Figures 1 to 4 The packaging structure includes a pallet 100 and a packaging box 200; the pallet 100 includes a support plate 110 and a plurality of support legs 120 respectively supported under the pallet 110; the packaging box 200 is arranged above the pallet 110 and fixedly connected to the pallet 110, and the packaging box 200 is used to accommodate a secondary protection screen cabinet 2000 for packaging; the support legs 120 include at least two support blocks 121 spaced apart from top to bottom and a buffer block 122 sandwiched between two adjacent support blocks 121, and the buffer block 122 is an elastic structure that can be retracted and deformed after being subjected to force.

[0033] Among them, the packing box 200 is used to pack the secondary protection screen cabinet 2000, and to define and protect the secondary protection screen cabinet 2000. The pallet 110 is made of wood material, and the pallet 110 is in the shape of a flat plate. Each support leg 120 is arranged at intervals below the pallet 110, and each support leg 120 is used to support the pallet 110 to a certain height. A plug-in space is formed between the support legs 120, and the plug-in space is convenient for a forklift to insert to lift the pallet 110, the packing box 200 and the secondary protection screen cabinet 2000 as a whole, thereby realizing the position transfer of the secondary protection screen cabinet 2000.

[0034] The number of the support blocks 121 can be two, three or more, and the buffer block 122 is sandwiched between two adjacent support blocks 121. The buffer block 122 has buffering elasticity. When strong bumps occur during transportation, the buffer blocks 122 in each support leg 120 can buffer the bumps, thereby reducing the impact of the bumps on the secondary protection screen cabinet 2000.

[0035] The packaging structure in the embodiment of the present application, the support legs 120 of the pallet 100 include at least two support blocks 121 arranged in sequence from top to bottom and a buffer block 122 sandwiched between two adjacent support blocks 121. Specifically, the support legs 120 are arranged as a multi-layer structure, and a buffer block 122 with retractable deformation is arranged between adjacent support blocks 121, that is, a buffer block 122 with buffering capacity is arranged between adjacent support blocks 121, so that during transportation, if strong bumps occur, the buffer blocks 122 in each support leg 120 can buffer the bumps, thereby reducing the impact of the bumps on the secondary protection screen cabinet 2000, and then the secondary protection screen cabinet 2000 can be effectively protected, so that the secondary protection screen cabinet 2000 still has the initial performance after transportation.

[0036] In one embodiment, the buffer block 122 is made of EPP material. EPP is a polypropylene plastic foam material, which is a highly crystalline polymer material with excellent performance. With its unique and superior performance, it has become the fastest growing environmentally friendly new type of pressure-resistant buffer insulation material. EPP products have very excellent shock-absorbing performance and high recovery rate after deformation. In addition, they are light in weight and can greatly reduce the weight of items. After simulation and actual measurement, the use of EPP foamed 20 times has the best buffering effect. It can be understood that in other embodiments of the present application, the above-mentioned buffer block 122 can also be made of ordinary foam, pearl cotton, EVA, soft silicone or other materials with buffering effect. In addition, the buffer block 122 can also be composed of a plurality of springs, which is not the only limitation here.

[0037] In one embodiment, see Figure 4, the support foot 120 includes a first support block 121a, a buffer block 122 and a second support block 121b, the first support block 121a, the buffer block 122 and the second support block 121b are stacked in sequence from top to bottom, and the first support block 121a, the buffer block 122 and the second support block 121b are fixed in sequence from top to bottom, that is, the first support block 121a, the buffer block 122 and the second support block 121b are fixed together. In this embodiment, the support foot 120 includes two support blocks 121, that is, the support foot 120 has a three-layer structure, so that the support foot 120 can have a buffering function on the basis of a fewer-layer structure, thereby ensuring the structural stability of the support foot 120. It can be understood that in other embodiments of the present application, the support foot 120 may also include three, four or more support blocks 121, which is not limited here.

[0038] In one embodiment, the first support block 121a and the second support block 121b are respectively adhered and fixed to opposite sides of the buffer block 122. By adhering and fixing, opposite sides of the buffer block 122 can be supported and fixed by the first support block 121a and the second support block 121b, so that the buffer block 122 can return to its original flat state after the external force disappears.

[0039] In one embodiment, see Figure 4 A mounting hole 123 is formed on the tray 100, which passes through the first support block 121a, the buffer block 122 and the second support block 121b in sequence; the packaging structure also includes a fastener 124, a locking member 125 and a spring washer 126. The fastener 124 includes a rod 1241 and a head 1242 that are connected to each other. The rod 1241 passes through the mounting hole 123, and one end of the rod 1241 away from the head 1242 is fixedly connected to the locking member 125. The locking member 125 is fixedly connected to the second support block 121b, and the spring washer 126 elastically abuts between the first support block 121a and the head 1242. Among them, since the spring gasket 126 elastically abuts between the first support block 121a and the head 1242, the distance between the head 1242 and the first support block 121a is adjustable. When the buffer block 122 expands and contracts due to strong bumps, the spring gasket 126 can expand and contract to adapt to the expansion and contraction of the buffer block 122, thereby ensuring the structural stability of the entire tray 100 while ensuring that the first support block 121a, the buffer block 122 and the second support block 121b are locked in sequence.

[0040] In one embodiment, see Figure 4The locking member 125 is a four-claw nut, which is sleeved on the rod 1241 of the fastener 124 and threadedly locked with the rod 1241. The upper surface of the four-claw nut abuts against the lower side of the second support block 121b, and the four claws of the four-claw nut are respectively embedded in the second support block 121b, thereby realizing the fixed connection between the four-claw nut and the second support block 121b.

[0041] In one embodiment, see Figure 4 A receiving groove 1210b connected to the mounting hole 123 is formed on the lower side of the second supporting block 121b, and the four-claw nut is received in the receiving groove 1210b, so as to prevent the four-claw nut from protruding from the lower side of the second supporting block 121b and affecting the supporting stability of the entire tray 100.

[0042] In one embodiment, see Figure 4 The rod 1241 is also sleeved with a flat washer 127, which is in contact between the first support block 121a and the head 1242. The provision of the flat washer 127 can eliminate the damage to the surface of the first support block 121a caused by the spring washer 126 during disassembly.

[0043] In one embodiment, see Figure 4 The support plate 110 is provided with a receiving hole 111 in communication with the mounting hole 123 at a position corresponding to the mounting hole 123, and the head 1242 of the fastener 124 and the spring washer 126 are both received in the receiving hole 111. During assembly, the fastener 124, the flat washer 127 and the spring washer 126 can be assembled downward from the top side of the receiving hole 111.

[0044] In one embodiment, see Figure 2 A plurality of rows of support legs 120 spaced apart in sequence are provided under the pallet 110, and the support blocks 121 at the bottom of each row of support legs 120 are integrally connected, that is, a plate is used as the bottom support block 121 of each support leg 120. By so configuring, the bottom of each row of support legs 120 can be connected together, thereby improving the structural strength of each row of support legs 120 and the supporting stability for the packaging box 200.

[0045] For details, please refer to Figure 2 , three rows of support legs 120 are arranged in sequence along the first direction X, and each support leg 120 in each row is arranged in sequence along the second direction Y, and the three support legs 120 arranged in sequence along the second direction Y share the support block 121 below, and the first direction X and the second direction Y are perpendicular to each other. It can be understood that in other embodiments of the present application, the support legs 120 arranged in sequence along the first direction X can also be connected. In addition, the support legs 120 can be two rows, four rows, or more than four rows, and the number of support legs 120 in each row can also be two, four, or more than four.

[0046] In one embodiment, see Figure 1 The packaging box 200 includes a box body 210 fixed on the pallet 110 and a cover body 220 covering the box body 210. Both the box body 210 and the cover body 220 are made of honeycomb paperboard. Among them, the honeycomb paperboard has better impact resistance. After simulation and actual measurement, the honeycomb paperboard with a thickness of 15mm and an inner honeycomb hole inscribed circle of 6mm can achieve the best buffering performance at a lower cost. In this embodiment, by making the box body 210 and the cover body 220 both of the honeycomb paperboard with better impact resistance, the four sides and the top of the secondary protection screen cabinet 2000 can have a good buffering effect, and the bottom support foot 120 has a buffering effect, so that the secondary protection screen cabinet 2000 can be effectively protected.

[0047] In one embodiment, see Figure 1 and Figure 7 The packaging box 200 further includes a bottom bracket 230, which includes a bottom edge 231 that is fitted and fixed on the periphery of the pallet 110 and a surrounding plate 232 that is connected to the outer periphery of the bottom edge 231; the box body 210 includes a plurality of side panels 211 that are connected end to end in sequence, the bottom end of each side panel 211 is fixed on the bottom edge 231, and the outer side of each side panel 211 is fitted with the inner side of each surrounding plate 232. In this embodiment, by setting the bottom bracket 230, the bottom end of each side panel 211 in the box body 210 can be limited and supported to ensure the structural strength of the bottom of the box body 210. In addition, since the bottom of the bottom bracket 230 only has the bottom edge 231, a frame structure, and the center is empty, when the secondary protection screen cabinet 2000 is loaded into the packaging box 200, the bottom of the secondary protection screen cabinet 2000 can be directly supported on the pallet 110, so that the support foot 120 has a better buffering effect on the secondary protection screen cabinet 2000, and can also reduce material costs and reduce overall weight and overall volume. It can be understood that in other embodiments of the present application, the bottom bracket 230 can also include a bottom plate, the center of the bottom plate is a solid, and the secondary protection screen cabinet 2000 is supported on the bottom plate, which is not the only limitation here.

[0048] Optionally, the side panel 211 and the bottom edge 231 can be glued together or connected by nails, and the side panel 211 and the enclosure panel 232 can be glued together or connected by nails.

[0049] In one embodiment, see Figure 5 and Figure 6, the packaging box 200 is enclosed to form an installation cavity 240, and each side corner of the installation cavity 240 is fixed with a buffer pad 250. For example, when the packaging box 200 is in the shape of a rectangular parallelepiped, the installation cavity 240 has four sides and four side corners, and each side corner is provided with a buffer pad 250. Then, when the secondary protection screen cabinet 2000 is loaded into the installation cavity 240, the four side corners of the secondary protection screen cabinet 2000 are all abutted against the buffer pad 250, and the buffer pad 250 has a buffering effect, so that the side corners of the secondary protection screen cabinet 2000 can be protected. It can be understood that in other embodiments of the present application, when the cross-section of the packaging box 200 is a polygon such as a pentagon or a hexagon, the installation cavity 240 has five, six or more corners, and each corner is provided with a buffer pad 250.

[0050] In one embodiment, see Figure 6 The installation cavity 240 has four corners, and there are eight buffer pads 250. The eight buffer pads 250 are respectively arranged at the upper and lower positions of the four corners, that is, a buffer pad 250 is arranged at the upper and lower positions of each corner. When the secondary protection screen cabinet 2000 is installed in the installation cavity 240, the upper and lower positions of the four corners of the secondary protection screen cabinet 2000 can abut against the buffer pads 250. In this way, the material consumption of the buffer pads 250 can be reduced while ensuring the buffering effect on the secondary protection screen cabinet 2000. It can be understood that in other embodiments of the present application, the buffer pads 250 can also be padded on the entire corners of the installation cavity 240, which is not the only limitation here.

[0051] Optionally, the cushion pad 250 is made of EPE material, which is also called pearl cotton, and has good softness and cushioning properties, good cushioning performance, light weight, and environmental protection. It can be understood that in other embodiments of the present application, the cushion pad 250 can also be made of other materials, such as ordinary foam, EPP, EVA, soft silicone or other materials with cushioning effect.

[0052] In one embodiment, see Figure 5 The buffer pad 250 is L-shaped and includes two vertically connected buffer portions 251 . The two buffer portions 251 are respectively disposed in contact with two adjacent side panels 211 of the box body 210 .

[0053] Optionally, the buffer pad 250 may be adhered to the box body 210 , or may be fixed to the box body 210 by wrapping with a wrapping film.

[0054] In one embodiment, see Figure 1 and Figure 8A first paper corner protector 260 is fixed to the outer side and the inner side of each corner of the packaging box 200 , wherein the first paper corner protector 260 serves to enhance the structural strength of each corner and also increases the structural strength of the entire packaging box 200 .

[0055] Specifically, the packaging box 200 includes a box body 210 , which includes four side panels 211 . The inner and outer sides of the connection between two adjacent side panels 211 are both provided with first paper corner protectors 260 , and the height of the first paper corner protectors 260 is the same as that of the side panels 211 .

[0056] Optionally, the material of the first paper corner protector 260 can be ordinary cardboard, which mainly serves to enhance the structural strength. The first paper corner protector 260 can be pasted on the box body 210, or can be fixed on the box body 210 by wrapping film.

[0057] In one embodiment, see Fig. 9 The outer sides of the four corners of the cover 220 are provided with second paper corner protectors 270 to enhance the structural strength of the cover 220. The second paper corner protectors 270 can be pasted on the cover 220 or fixed on the cover 220 by wrapping film.

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
