Description

Refrigerator Packaging Structure Technical Field

[0001] This invention relates to the field of home appliance packaging technology, and more particularly to refrigerator packaging structure. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. During transportation, refrigerators are subject to uncontrollable factors, which may lead to damage and unnecessary waste. Therefore, refrigerators need to be properly packaged and secured before transportation to enhance their protection.

[0003] In relevant technologies, refrigerator packaging mostly uses cardboard boxes and EPS (Expandable Polystyrene) materials, with wooden frames and crates serving as cushioning. The refrigerator is placed in a cardboard box, with EPS material sandwiched between the top and bottom. However, EPS material is not only too expensive to produce, but if not properly recycled, it can damage the environment, hindering environmental protection. Furthermore, during actual transportation, refrigerator damage is mainly concentrated on the top and side edges; existing packaging structures that only sandwich EPS material between the top and bottom edges cannot effectively protect the side edges.

[0004] Therefore, there is an urgent need to invent a refrigerator packaging structure to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigerator packaging structure that uses paper materials to package the refrigerator and effectively protects the top and side edges of the refrigerator, with high structural strength.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The refrigerator packaging structure includes a container made of paper material, a top cushioning structure, a side cushioning structure, a bottom cushioning structure, a top reinforcement structure, and a side reinforcement structure.

[0008] The housing has a receiving cavity, in which the refrigerator, the top buffer structure, the side buffer structure, the bottom buffer structure, the top reinforcing structure, and the side reinforcing structure are all housed;

[0009] The top buffer structure is disposed above the refrigerator, and the top buffer structure can provide impact cushioning for the top of the refrigerator;

[0010] The side buffer structure is disposed outside the side edge of the refrigerator, and the side buffer structure can provide collision buffer for the side edge of the refrigerator.

[0011] The bottom buffer structure is located below the refrigerator, and the bottom buffer structure can support and position the refrigerator and provide collision buffer for the bottom of the refrigerator;

[0012] The top reinforcing structure is disposed above the top buffer structure, and the top reinforcing structure is configured to improve the structural strength of the top buffer structure.

[0013] The side reinforcement structure is disposed on the outside of the side buffer structure, and the side reinforcement structure is configured to improve the structural strength of the side buffer structure.

[0014] As an optional solution, the housing includes:

[0015] The main body of the cabinet contains a receiving cavity, and a second opening is provided at the lower end of the receiving cavity. The refrigerator, the top buffer structure, the side buffer structure, the bottom buffer structure, the top reinforcing structure, and the side reinforcing structure enter the receiving cavity through the second opening.

[0016] Cable ties are used to bind the outer periphery of the main body of the box around the vertical and horizontal axes respectively. The outer periphery wall of the main body of the box is provided with a tear structure, and the structural strength of the tear structure is lower than the structural strength of the rest of the main body of the box.

[0017] As an optional solution, the top buffer structure includes:

[0018] The first main body is positioned above the refrigerator; and

[0019] The first buffer portion is provided at both ends of the first main body, which are respectively disposed opposite to each other. The first buffer portion extends downward from the lower end of the first main body and abuts against the upper end of the refrigerator.

[0020] As an optional solution, the top buffer structure is formed by folding a first plate. The first plate includes a first bend, a second bend, a third bend, and a fourth bend. The two ends of the first bend are respectively provided with second bends. Each second bend is connected to a third bend that moves relative to the first bend. The end of each third bend that is opposite to the second bend is connected to the fourth bend.

[0021] The fourth bend, the third bend, and the second bend are folded in sequence to form the first buffer section, and the first bend section forms the first main body.

[0022] As an optional solution, the first plate body further includes:

[0023] The first fastener is disposed inside the first bending portion and can be folded relative to the first bending portion. The second bending portion has a first locking opening. When the fourth bending portion, the third bending portion, and the second bending portion are folded into the first buffer portion in sequence, the first fastener is locked and fixed with the first locking opening.

[0024] As an optional solution, the bottom buffer structure includes:

[0025] Positioning box;

[0026] The first buffer and the second buffer are provided. The positioning box has a positioning cavity with a first opening at the upper end of the positioning cavity. The second buffer, the first buffer, and the bottom of the refrigerator are sequentially arranged in the positioning cavity from bottom to top along the first opening. The first buffer can support and position the bottom of the refrigerator in the vertical direction and provide collision buffer for both ends of the bottom of the refrigerator in the first direction. The second buffer can provide collision buffer for both ends of the bottom of the refrigerator in the second direction. The first direction and the second direction are parallel to the horizontal plane and perpendicular to each other.

[0027] As an optional solution, the first buffer includes:

[0028] The second subject; and

[0029] The second buffer portion is disposed at both ends of the second main body along the first direction. The second buffer portion extends upward from the upper end surface of the second main body and abuts against the lower end surface of the refrigerator. The upper end surface of the second buffer portion is provided with a positioning hole, which is inserted and positioned with the support foot provided on the lower end surface of the refrigerator.

[0030] As an optional solution, the first buffer is formed by folding a second plate. The second plate includes a fifth bend, a sixth bend, a seventh bend, and an eighth bend. The sixth bend is connected to the two opposite ends of the fifth bend along the first direction. The seventh bend is connected to the end of each sixth bend away from the fifth bend along the first direction. The eighth bend is connected to the end of each seventh bend away from the sixth bend along the first direction.

[0031] The eighth bend, the seventh bend, and the sixth bend are folded in sequence to form the second buffer section, and the fifth bend forms the second main body;

[0032] The sixth bend, the seventh bend, and the eighth bend are all provided with positioning holes. When the eighth bend, the seventh bend, and the sixth bend are folded into the second buffer portion, the positioning holes in the sixth bend, the seventh bend, and the eighth bend are coaxially connected.

[0033] As an optional solution, the top reinforcement structure includes:

[0034] Two first reinforcing beams arranged opposite each other along a first direction, each of the first reinforcing beams extending along a second direction; and

[0035] Two second reinforcing beams are arranged opposite each other along the second direction. Each second reinforcing beam extends along the first direction. The cross-sections of the first and second reinforcing beams are both L-shaped. The first and second directions are perpendicular to each other in the horizontal plane. The first and second reinforcing beams form a rectangular structure and together cover the top buffer structure.

[0036] As an optional solution, the side buffer structure includes:

[0037] First buffer plate; and

[0038] The second buffer plate is fixed to the first buffer plate. Both the first and second buffer plates extend in the vertical direction. The cross-sections of the first and second buffer plates are L-shaped. The side edge of the refrigerator is accommodated in the space formed by the L-shaped first and second buffer plates.

[0039] The beneficial effects of this invention are:

[0040] The refrigerator packaging structure provided by this invention, by setting a receiving cavity inside the receiving box, houses the refrigerator, top buffer structure, side buffer structure, and bottom buffer structure within the receiving cavity. The top buffer structure is positioned above the refrigerator to provide impact cushioning for the top of the refrigerator; the side buffer structures are positioned on the side edges of the refrigerator to provide impact cushioning for the side edges; and the bottom buffer structure is positioned below the refrigerator to support and position it while providing impact cushioning for the bottom. This achieves cushioning packaging for the refrigerator. By placing the top reinforcement structure and the side reinforcement structure within the receiving cavity, with the top reinforcement structure positioned above the top buffer structure to enhance the structural strength of the top buffer structure, and the side reinforcement structure positioned outside the side buffer structure to enhance its structural strength, reinforced protection is achieved for the top and side edges of the refrigerator, further improving the protective effect on the refrigerator. Furthermore, since the housing, top cushioning structure, side cushioning structure, bottom cushioning structure, top reinforcement structure, and side reinforcement structure are all made of paper materials, it not only improves environmental protection but also enables the recycling of the refrigerator packaging structure, reducing the production cost of the refrigerator packaging structure.

[0062] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0063] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0064] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0065] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0066] To improve the protection of refrigerators during transportation, they need to be secured in packaging before transport. Current technologies typically use cardboard boxes and Expandable Polystyrene (EPS) materials for packaging, with wooden frames and crates serving as cushioning. The refrigerator is placed in a cardboard box, with EPS material sandwiched between the top and bottom. However, EPS material is not only expensive to produce, but if not properly recycled, it can damage the environment. Furthermore, in actual transportation, damage to refrigerators is mainly concentrated on the top and side edges; existing packaging structures that only sandwich EPS material between the top and bottom cannot effectively protect the side edges.

[0067] To address the aforementioned problems, as shown in Figure 1, this embodiment provides a refrigerator packaging structure. This refrigerator packaging structure includes a receiving box 600 made of paper material, a top cushioning structure 100, a side cushioning structure 200, a bottom cushioning structure 300, a top reinforcing structure 400, and a side reinforcing structure 500. The receiving box 600 has a receiving cavity, within which the refrigerator 2000, the top cushioning structure 100, the side cushioning structure 200, the bottom cushioning structure 300, the top reinforcing structure 400, and the side reinforcing structure 500 are all housed. The top cushioning structure 100 is positioned above the refrigerator 2000, providing impact cushioning for the top of the refrigerator 2000. The side cushioning structure 200... The side buffer structure 200 is located outside the side edge of the refrigerator 2000 and provides collision buffer for the side edge of the refrigerator 2000. The bottom buffer structure 300 is located below the refrigerator 2000 and can support and position the refrigerator 2000 and provide collision buffer for the bottom of the refrigerator 2000. The top reinforcement structure 400 is located above the top buffer structure 100 and is configured to improve the structural strength of the top buffer structure 100. The side reinforcement structure 500 is located outside the side buffer structure 200 and is configured to improve the structural strength of the side buffer structure 200.

[0068] The refrigerator packaging structure, by providing a receiving cavity within the receiving box 600, houses the refrigerator 2000, top buffer structure 100, side buffer structure 200, and bottom buffer structure 300 within the receiving cavity. The top buffer structure 100 is positioned above the refrigerator 2000 to provide impact cushioning for the top of the refrigerator 2000; the side buffer structures 200 are positioned along the side edges of the refrigerator 2000 to provide impact cushioning for the side edges; and the bottom buffer structure 300 is positioned below the refrigerator 2000 to support and position the refrigerator 2000. The bottom provides impact cushioning, achieving buffered packaging for the refrigerator 2000. By placing the top reinforcing structure 400 and the side reinforcing structure 500 within the receiving cavity, and positioning the top reinforcing structure 400 above the top cushioning structure 100, the structural strength of the top cushioning structure 100 is enhanced. Similarly, the side reinforcing structure 500 is positioned outside the side cushioning structure 200, further increasing its structural strength. This provides reinforced protection for the top and side edges of the refrigerator 2000, further improving its protective effect. Furthermore, since the receiving box 600, top cushioning structure 100, side cushioning structure 200, bottom cushioning structure 300, top reinforcing structure 400, and side reinforcing structure 500 are all made of paper, not only is environmental protection improved, but the refrigerator packaging structure can also be recycled, reducing production costs.

[0069] As an optional solution, as shown in Figure 2, the top buffer structure 100 includes a first main body 110 and a first buffer portion 120. The first main body 110 covers the refrigerator 2000, and the first buffer portion 120 is respectively provided at both opposite ends of the first main body 110. The first buffer portion 120 extends downward from the lower end of the first main body 110 and abuts against the upper end surface of the refrigerator 2000. By providing the first buffer portion 120 at both opposite ends of the first main body 110, so that the first main body 110 covers the refrigerator 2000 and the first buffer portion 120 extends downward and abuts against the upper end surface of the refrigerator 2000, the upper end surface of the refrigerator 2000 can be protected while the first buffer portion 120 provides collision buffering for the upper end surface of the refrigerator 2000.

[0070] Specifically, as shown in Figure 3, the top buffer structure 100 is formed by folding a first plate 1. The first plate 1 includes a first bent portion 11, a second bent portion 12, a third bent portion 13, and a fourth bent portion 14. The two ends of the first bent portion 11 are respectively provided with second bent portions 12. Each second bent portion 12 is connected to a third bent portion 13 that moves relative to the first bent portion 11. Each third bent portion 13 is connected to a fourth bent portion 14 at one end opposite to the second bent portion 12. The fourth bent portion 14, the third bent portion 13, and the second bent portion 12 are folded in sequence to form a first buffer portion 120. The first bent portion 11 forms the first main body 110. By centering on the first bending part 11, connecting the second bending part 12, the third bending part 13, and the fourth bending part 14 outward from the opposite ends of the first bending part 11, the two sets of fourth bending parts 14, third bending parts 13, and second bending parts 12 are folded in sequence to form the first buffer part 120, and the first bending part 11 is used as the first main body 110, thus realizing the flipping assembly of the top buffer structure 100. The structure is simple, the assembly is convenient, and the assembly efficiency is high.

[0071] To further improve the structural strength of the top buffer structure 100, the first plate 1 also includes a first fastener 15, wherein the first fastener 15 is disposed inside the first bending portion 11 and can be folded relative to the first bending portion 11. A first locking opening 16 is provided on the second bending portion 12. When the fourth bending portion 14, the third bending portion 13 and the second bending portion 12 are folded into the first buffer portion 120 in sequence, the first fastener 15 is locked and fixed with the first locking opening 16. By providing a first fastener 15 in the first bending portion 11 and a first locking opening 16 in the second bending portion 12, when the fourth bending portion 14, the third bending portion 13, and the second bending portion 12 are folded relative to the first bending portion 11 to form the first buffer portion 120, the first fastener 15 can be engaged and fixed with the first locking opening 16, thereby assembling and fixing the folded first buffer portion 120 with the first main body 110. This solves the problem that the first buffer portion 120 in the folding direction is restored to the second bending portion 12, the third bending portion 13, and the fourth bending portion 14 connected in sequence.

[0072] In addition, in other embodiments, in order to further improve the fixing effect between the first buffer part 120 and the first main body 110, the number of the first fasteners 15 can be adjusted according to actual needs. It is only necessary to ensure that each first fastener 15 is set with a corresponding first fastening port 16. This embodiment does not make specific limitations.

[0073] In an optional embodiment, as shown in Figures 1 and 4, the top reinforcing structure 400 includes two first reinforcing beams 410 arranged opposite each other along a first direction and two second reinforcing beams 420 arranged opposite each other along a second direction. Each first reinforcing beam 410 extends along the second direction, and each second reinforcing beam 420 extends along the first direction. The cross-sections of both the first reinforcing beams 410 and 420 are L-shaped. The first reinforcing beams 410 and 420 form a rectangular structure and together cover the top buffer structure 100. By using the two L-shaped first reinforcing beams 410 extending along the second direction and the two second reinforcing beams 420 extending along the first direction to form a rectangular structure, and covering the top buffer structure 100 with this rectangular structure, the top buffer structure 100 can be protected from its upper surface and side surface, especially for the upper corner of the top buffer structure 100. It should be noted that in this embodiment, the thickness of the first reinforcing beam 410 is 5mm, and the distance extending along the second direction is 520mm. The thickness of the second reinforcing beam 420 is 5mm, and the distance extending along the first direction is 450mm. Furthermore, the height and width of the L-shaped cross-section within both the first and second reinforcing beams 410 and 420 are 50mm. In other embodiments, the specific dimensions of the first and second reinforcing beams 410 and 420 can be adaptively adjusted according to the actual dimensions of the refrigerator 2000; this embodiment does not impose specific limitations.

[0074] As an optional solution, as shown in Figure 1, the bottom buffer structure 300 includes a positioning box 330, a first buffer member 310, and a second buffer member 320. The positioning box 330 has a positioning cavity with a first opening at the upper end. The second buffer member 320, the first buffer member 310, and the bottom end of the refrigerator 2000 are sequentially arranged in the positioning cavity from bottom to top along the first opening. The first buffer member 310 can support the bottom end of the refrigerator 2000 in the vertical direction and provide collision buffering for both ends of the bottom of the refrigerator 2000 along the first direction. The second buffer member 320 can provide collision buffering for both ends of the bottom of the refrigerator 2000 along the second direction. The first direction and the second direction are parallel to the horizontal plane and perpendicular to each other. By opening a first opening at the upper end of the positioning cavity inside the positioning box 330, the second buffer 320, the first buffer 310, and the bottom end of the refrigerator 2000 are sequentially arranged in the positioning cavity from bottom to top along the first opening. This achieves the assembly and positioning of the first buffer 310, the second buffer 320, and the lower end of the refrigerator 2000. By having the first buffer 310 provide collision buffering for both ends of the bottom of the refrigerator 2000 along the first direction, and the second buffer 320 provide collision buffering for both ends of the bottom of the refrigerator 2000 along the second direction, it is ensured that the first direction and the second direction are parallel to and perpendicular to the horizontal plane, providing stable and comprehensive collision buffering for the lower end surface of the refrigerator 2000, resulting in good protection for the refrigerator 2000.

[0075] Since the refrigerator is cubic in shape, to further improve the protection of the refrigerator 2000, the first direction is the length direction of the refrigerator 2000, and the second direction is the width direction of the refrigerator 2000. It should be noted that in this embodiment, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. In other embodiments, the first and second directions can be adjusted according to actual needs; this embodiment does not impose specific limitations.

[0076] Specifically, as shown in Figures 5 and 6, the first buffer member 310 includes a second main body 311 and a second buffer part 312. The second buffer part 312 is disposed at both ends of the second main body 311 along the first direction. The second buffer part 312 extends upward from the upper end surface of the second main body 311 and abuts against the lower end surface of the refrigerator 2000. The upper end surface of the second buffer part 312 is provided with a positioning hole 3121, which is inserted and positioned with the support foot 2100 provided on the lower end surface of the refrigerator 2000. By setting the first buffer 310 as the second main body 311 and the second buffer portions 312 respectively set at both ends of the second main body 311 along the first direction, the second buffer portions 312 extend upward from the upper end surface of the second main body 311 and abut against the lower end surface of the refrigerator 2000, thus achieving buffer support for the bottom of the refrigerator 2000. By setting the positioning hole 3121 on the upper end surface of the second buffer portion 312, and inserting the positioning hole 3121 into the support foot 2100 on the lower end surface of the refrigerator 2000 for positioning, not only can the buffering effect on the lower end surface of the refrigerator 2000 be improved, but the positioning accuracy between the first buffer 310 and the refrigerator 2000 can also be further improved, thus assembling and positioning the first buffer 310 and the refrigerator 2000 together. It should be noted that in this embodiment, the lower end face of the refrigerator 2000 is provided with four support feet 2100, and each of the two second buffer portions 312 is provided with two positioning holes 3121, so that each support foot 2100 is inserted and positioned with one positioning hole 3121. In other embodiments, the specific number of positioning holes 3121 can be adjusted according to the specific number of support feet 2100 on the refrigerator 2000, and this embodiment does not make a specific limitation.

[0077] In this embodiment, as shown in FIG7, the first buffer member 310 is formed by folding the second plate 2. The second plate 2 includes a fifth bend 21, a sixth bend 22, a seventh bend 23, and an eighth bend 24. The sixth bend 22 is connected to the two opposite ends of the fifth bend 21 along the first direction. The seventh bend 23 is connected to the end of each sixth bend 22 away from the fifth bend 21 along the first direction. The eighth bend 24 is connected to the end of each seventh bend 23 away from the sixth bend 22 along the first direction. 24. The eighth bend 24, the seventh bend 23, and the sixth bend 22 are folded in sequence to form the second buffer part 312. The fifth bend 21 forms the second main body 311. The sixth bend 22, the seventh bend 23, and the eighth bend 24 are all provided with positioning holes 3121. When the eighth bend 24, the seventh bend 23, and the sixth bend 22 are folded into the second buffer part 312, the positioning holes 3121 in the sixth bend 22, the seventh bend 23, and the eighth bend 24 are coaxially connected. By connecting the fifth bend 21 as the center, the sixth bend 22, the seventh bend 23, and the eighth bend 24 are sequentially connected outward from both ends of the fifth bend 21 along the first direction, so that the two sets of the sixth bend 22, the seventh bend 23, and the eighth bend 24 are folded together to form the second buffer part 312. Positioning holes 3121 are provided on the sixth bend 22, the seventh bend 23, and the eighth bend 24 respectively, to ensure that the positioning holes 3121 in the sixth bend 22, the seventh bend 23, and the eighth bend 24 are coaxially connected when the sixth bend 22, the seventh bend 23, and the eighth bend 24 are folded into the second buffer part 312. This increases the depth of the positioning holes 3121, so that the upper end face of the second buffer part 312 abuts against the lower end face of the refrigerator 2000 after the support foot 2100 is inserted and positioned with the positioning hole 3121. Similarly, the fifth bend 21 is provided with a second fastener 25, and the sixth bend 22 is provided with a second fastening opening 26. The specific structures of the second fastener 25 and the second fastening opening 26 are the same as those of the first fastener 15 and the first fastening opening 16, and will not be described again here.

[0078] It should be noted that the specific structure of the second buffer 320 is the same as that of the top buffer structure 100. To keep the text concise, the specific structure of the second buffer 320 will not be described in detail here.

[0079] The specific structure of the positioning box 330 is described with reference to Figure 8. The positioning box 330 is formed by folding the third plate 3. The third plate 3 includes a ninth bend 31, a tenth bend 32 located at both ends of the ninth bend 31 along a first direction, an eleventh bend 33 located at both ends of the ninth bend 31 along a second direction, and a twelfth bend 34 located at both ends of each tenth bend 32 along a second direction. The tenth bend 32 and the eleventh bend 33 together flip relative to the ninth bend 31 to form a frame structure. The twelfth bend 34 is provided with adhesive, and the twelfth bend 34 glues and fixes the frame structure to complete the assembly of the positioning box 330.

[0080] In some alternative solutions, as shown in Figure 9, the side buffer structure 200 includes a first buffer plate 210 and a second buffer plate 220. The second buffer plate 220 is fixed to the first buffer plate 210. Both the first buffer plate 210 and the second buffer plate 220 extend vertically, and their cross-sections are L-shaped. The side edges of the refrigerator 2000 are accommodated in the L-shaped space formed by the first buffer plate 210 and the second buffer plate 220. By combining the first buffer plate 210 and the second buffer plate 220 extending vertically into an L-shaped cross-section, the side edges of the refrigerator 2000 are accommodated in the L-shaped space, effectively protecting the side edges of the refrigerator 2000. It should be noted that in this embodiment, the refrigerator packaging structure has four side buffer structures 200, each corresponding to one of the four side edges of the refrigerator 2000. Furthermore, both the first buffer plate 210 and the second buffer plate 220 are made of honeycomb cardboard. Honeycomb panels have many advantages, including being lightweight, strong, stable, heat-insulating, and shock-resistant. In other embodiments, the first buffer plate 210 and the second buffer plate 220 can also be corrugated cardboard or other paperboard supported by pulp; this embodiment does not impose specific limitations.

[0081] Furthermore, in this embodiment, the distance between the first buffer plate 210 and the second buffer plate 220 extending in the vertical direction is 710mm, and the height of the L-shaped cross-section formed by the first buffer plate 210 and the second buffer plate 220 is 100mm, and the width is 80mm. In other embodiments, the dimensions of the first buffer plate 210 and the second buffer plate 220 can be adjusted according to actual needs; this embodiment does not impose specific limitations.

[0082] Furthermore, in this embodiment, the side reinforcement structure 500 includes a third reinforcing beam extending in the vertical direction. The third reinforcing beam has an L-shaped cross-section and is disposed on the outer periphery of the first buffer plate 210 and the second buffer plate 220. It should be noted that the specific structure of the third reinforcing beam is the same as that of the first reinforcing beam 410 and the second reinforcing beam 420, differing only in its dimensions. For the sake of brevity, the specific structure of the third reinforcing beam will not be described in detail here.

[0083] As an optional solution, the housing 600 includes a housing body and cable ties. The housing body has a housing cavity, and the lower end of the housing cavity has a second opening. The refrigerator 2000, the top buffer structure 100, the side buffer structure 200, the bottom buffer structure 300, the top reinforcing structure 400, and the side reinforcing structure 500 enter the housing cavity through the second opening. The cable ties are tied around the vertical axis and the horizontal axis respectively to the outer periphery of the housing body. The outer periphery wall of the housing body is provided with a tear structure. The structural strength of the tear structure is lower than the structural strength of the rest of the housing body. By opening a second opening at the lower end of the main body of the box, the refrigerator 2000, top buffer structure 100, side buffer structure 200, bottom buffer structure 300, top reinforcing structure 400, and side reinforcing structure 500 can enter the receiving cavity through the second opening. By using cable ties wrapped around the vertical and horizontal axes to tie the outer perimeter of the main body of the box, the second opening can be sealed to prevent the refrigerator 2000, top buffer structure 100, side buffer structure 200, bottom buffer structure 300, top reinforcing structure 400, and side reinforcing structure 500 from leaving the receiving cavity through the second opening, thus achieving stable packaging and fixation of the refrigerator 2000. By setting a tear structure in the main body of the box, when the refrigerator 2000 is subsequently removed from the refrigerator packaging structure, the refrigerator packaging structure can be disassembled by tearing the main body of the box along the tear structure, thereby improving the efficiency of subsequent disassembly of the refrigerator packaging structure.

[0084] Specifically, as shown in Figure 10, the main body of the box is formed by folding the fourth plate 4. The fourth plate 4 includes a thirteenth bend 41, a fourteenth bend 42, a fifteenth bend 43, a sixteenth bend 44, a seventeenth bend 45, an eighteenth bend 46, a nineteenth bend 47, and a twentieth bend 48. The thirteenth bend 41, the fourteenth bend 42, the fifteenth bend 43, and the sixteenth bend 44 are connected in sequence. The seventeenth bend 45 is connected to the thirteenth bend 41, the eighteenth bend 46 is connected to the fourteenth bend 42, the nineteenth bend 47 is connected to the fifteenth bend 43, and the twentieth bend 48 is connected to the sixteenth bend 44. The seventeenth bend 45, the eighteenth bend 46, the nineteenth bend 47, and the twentieth bend 48 are located on the same side. When assembling the main body of the box, first form a cylindrical structure by folding the thirteenth bend 41, the fourteenth bend 42, the fifteenth bend 43 and the sixteenth bend 44, and then fold the seventeenth bend 45, the eighteenth bend 46, the nineteenth bend 47 and the twentieth bend 48 in sequence to seal one end of the cylindrical structure.

[0085] Furthermore, the tear structure includes a transverse tear line 610 and a longitudinal tear line 620. The thirteenth bend 41, fourteenth bend 42, fifteenth bend 43, and sixteenth bend 44 are all provided with transverse tear lines 610, and the thirteenth bend 41 is provided with a longitudinal tear line 620, which intersects with the transverse tear line 610. When the thirteenth bend 41, fourteenth bend 42, fifteenth bend 43, and sixteenth bend 44 form a cylindrical structure, the transverse tear line 610 circumferentially surrounds the cylindrical structure, and the longitudinal tear line 620 extends vertically.

[0086] It should be noted that in this embodiment, the thickness of the fourth plate 4 is reduced to form the transverse tear line 610 and the longitudinal tear line 620. In other embodiments, the structural strength of the tear structure can also be reduced by punching holes at intervals along the extension direction of the transverse tear line 610 and the longitudinal tear line 620; this embodiment does not specifically limit this.

[0087] To facilitate understanding of the refrigerator packaging structure provided in this embodiment, the specific packaging steps of the refrigerator packaging structure will now be explained with reference to Figures 1 to 10:

[0088] 1) Place the second buffer 320 and the first buffer 310 into the positioning box 330 in sequence;

[0089] 2) Place the lower end of the refrigerator 2000 into the positioning box 330, and fix the support foot 2100 of the refrigerator 2000 into the positioning hole 3121.

[0090] 3) Place the top buffer structure 100 on top of the refrigerator 2000;

[0091] 4) Place the top reinforcing structure 400 on top of the top buffer structure 100;

[0092] 5) Place the side buffer structure 200 on the outside of the side edge of the refrigerator 2000;

[0093] 6) Place the side reinforcement structure 500 on the outside of the side buffer structure 200;

[0094] 7) The main body of the cabinet is placed on the outside of the refrigerator 2000, the top buffer structure 100, the side buffer structure 200, the bottom buffer structure 300, the top reinforcing structure 400, and the side reinforcing structure 500.

[0095] 8) Tie the cable ties around the horizontal and vertical axes to the outside of the main body of the box.

[0096] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
