[0037] The realization of the purpose, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0039] First, for the packaging of fragile and vulnerable products, existing packaging boxes mainly include an outer box body and a foam cushion. The foam cushion is arranged inside the outer box body and wraps around the fragile and vulnerable product, thereby forming a buffer for the fragile and vulnerable product to avoid breakage or damage due to collision during transportation. However, the foam cushion is relatively large in size, resulting in high storage and transportation costs for the packaging box. Moreover, the foam cushion is prone to shedding of foam particles, leading to a poor consumer experience.

[0040] To solve the above technical problems, the present application proposes a packaging box 100, as Figure 1 shown. The packaging box 100 mainly includes an outer box body 10 and a peripheral sheath 20, and the outer box body 10 and the peripheral sheath 20 are respectively made of cardboard.

[0041] Among them, as Figure 1 shown, the outer box body 10 is provided with an installation cavity 11. The installation cavity 11 has an opposite cavity bottom (not shown) and a cavity opening 111, and the cavity bottom is provided with a first buffer structure 40. Specifically, in this embodiment, the outer box body 10 is made of cardboard. For example, the outer box body 10 can be folded from a single cardboard or spliced by multiple cardboards. The outer shape of the outer box body 10 is a cuboid structure, and the internal installation cavity 11 is also a rectangular cavity for packaging a product with a cuboid shape.

[0042] Of course, in other embodiments, according to the actual shape of the product to be packaged 200, the outer box body 10 can also be designed into other shapes. For example, when the outer shape of the product to be packaged 200 is cylindrical, the outer box body 10 can also be set as cylindrical, or when the product to be packaged 200 is other multi-prismatic shapes (such as triangular prism, pentagonal prism, hexagonal prism, octagonal prism, etc.), the outer box body 10 can be set as the corresponding multi-prismatic shape to adapt to packaging the product to be packaged 200 with the corresponding shape.

[0043] An installation cavity 11 for placing the product to be packaged 200 is provided inside the outer box body 10. The volume of the installation cavity 11 is larger than the volume of the product to be packaged 200. Specifically, taking the installation cavity 11 as a cuboid shape as an example, the length, width, and depth of the installation cavity 11 are respectively greater than the length, width, and height of the product to be packaged 200. In this way, the product to be packaged 200 can be completely wrapped, and a buffer structure can be arranged between the outer surface of the product to be packaged 200 and the inner surface of the installation cavity 11.

[0044] The installation cavity 11 has a cavity bottom and a cavity opening 111 that are opposite to each other along its depth direction. During packaging, the product 200 to be packaged is placed into the installation cavity 11 through the cavity opening 111, and the bottom surface of the product 200 to be packaged abuts against the cavity bottom. In this embodiment, a first buffer structure 40 is provided on the cavity bottom. The first buffer structure 40 is used to buffer the bottom surface of the product 200 to be packaged. In this way, when the bottom surface of the packaging box 100 collides with an external object, the first buffer structure 40 can buffer the bottom surface of the product 200 to be packaged, avoiding the situation where the external object directly impacts the product 200 to be packaged and causes the product 200 to be packaged to break or be damaged.

[0045] It should be noted here that the first buffer structure 40 can be a cushion plate, cushion block, cushion strip, buffer bump, etc. made of cardboard. In addition, the first buffer structure 40 can be integrally formed with the outer box body 10 or can be independent of the outer box body 10.

[0046] For example, the first buffer structure 40 can be a cushion plate folded from cardboard into multiple layers. The surface area of the cushion plate is larger than the area of the bottom surface of the product 200 to be packaged. Furthermore, it can buffer any position on the bottom surface of the product 200 to be packaged, and the cushion plate can be integrally formed with the outer box body 10. For example, the cushion plate is folded from a part of the plate body of the outer box body 10; or, the cushion plate can also be folded from cardboard independent of the outer box body 10. When packaging the product 200 to be packaged, first place the cushion plate into the cavity bottom of the installation cavity 11 through the cavity opening 111, and then place the product 200 to be packaged so that the bottom surface of the product 200 to be packaged is supported on the cushion plate.

[0047] For another example, the first buffer structure 40 can be multiple cushion strips, cushion blocks or buffer bumps formed by the protrusion of the cavity bottom part. The multiple cushion strips, cushion blocks or buffer bumps jointly support the bottom surface of the product 200 to be packaged, so as to buffer the bottom surface of the product 200 to be packaged.

[0048] For the buffering of the outer peripheral surface of the product 200 to be packaged, the packaging box 100 of the present application is further provided with a circumferential side sheath 20. The circumferential side sheath 20 is also made of cardboard. For example, the circumferential side sheath 20 can be folded from a single cardboard or spliced from multiple cardboards. When in use, the circumferential side sheath 20 is arranged in the installation cavity 11 and is used to cover the outer periphery of the product 200 to be packaged, and the circumferential side sheath 20 is convexly provided with buffer protrusions 21 on its outer peripheral surface.

[0049] Specifically, in this embodiment, as Figure 1 shown, the circumferential side sheath 20 is used to cover the outside of the product 200 to be packaged with a cuboid shape. Therefore, the circumferential side sheath 20 is set to be a cuboid annular column. Of course, in other embodiments, when the product 200 to be packaged is designed in other shapes, the circumferential side sheath 20 can also be adaptively set to other shapes.

[0050] For example, when the product 200 to be packaged is cylindrical, the circumferential sheath 20 can be set as a cylindrical shape with a hollow interior, so that it can better fit over the product 200 to be packaged. Another example is that when the product 200 to be packaged is a multi-prismatic shape (such as a triangular prism, pentagonal prism, hexagonal prism, octagonal prism, etc.), the circumferential sheath 20 can be set as the corresponding multi-prismatic shape to better fit over the product 200 to be packaged.

[0051] Crucially, in this embodiment, as Figure 1 or Figure 2 shown, buffer protrusions 21 are also convexly provided on the outer peripheral surface of the circumferential sheath 20. During packaging, the circumferential sheath 20 is fitted over the outer periphery of the product 200 to be packaged and is placed together with the product 200 to be packaged into the installation cavity 11 of the outer box body 10. At this time, the buffer protrusions 21 on the circumferential sheath 20 are located between the outer peripheral surface of the circumferential sheath 20 and the inner peripheral surface of the installation cavity 11. Thus, a buffer space is formed between the outer peripheral surface of the circumferential sheath 20 and the inner peripheral surface of the installation cavity 11, that is, a layer of buffer space surrounds the outer periphery of the product 200 to be packaged. In this way, when the outer peripheral surface of the outer box body 10 is impacted by an external object, the external object will not directly impact the outer peripheral surface of the product 200 to be packaged, avoiding the situation where the product 200 to be packaged is collided and broken or damaged.

[0052] It should be noted here that the buffer protrusions 21 can be convex flakes, convex blocks or convex strips, and the specific positions of the buffer protrusions 21 on the outer peripheral surface of the circumferential sheath 20 can be flexibly selected according to needs, as long as the buffer protrusions 21 can form a buffer space between the outer peripheral surface of the circumferential sheath 20 and the inner peripheral surface of the installation cavity 11.

[0053] For example, when the circumferential sheath 20 is cylindrical, the buffer protrusions 21 can be convex blocks, and there are multiple buffer protrusions 21, which are arranged at intervals along the circumferential direction of the circumferential sheath 20. Or, when the circumferential sheath 20 is multi-prismatic, the buffer protrusions 21 can be at the side edges 22, or on the side walls 23, or there are buffer protrusions 21 on both the side edges 22 and the side walls 23.

[0054] In summary, the first buffer structure 40 buffers the bottom surface of the product 200 to be packaged, the circumferential sheath 20 buffers the outer peripheral surface of the product 200 to be packaged, and for the buffering of the top surface of the product 200 to be packaged, in this application, as Figure 1 shown, the circumferential sheath 20 and / or the outer box body 10 are also provided with a second buffer structure 50 at the cavity opening 111, and the second buffer structure 50 is used to buffer the top surface of the product.

[0055] Specifically, in this embodiment, the second buffer structure 50 can be formed in various ways. For example, the second buffer structure 50 can be formed on the peripheral sheath 20. The second buffer structure 50 is located at one end of the peripheral sheath 20 close to the cavity opening 111, and the second buffer structure 50 can be a buffer convex plate 25. The buffer convex plate 25 protrudes relative to the top surface of the product to be packaged 200, so that a buffer space can be formed between the top surface of the product to be packaged 200 and the top surface of the outer box 10, avoiding direct impact of external objects on the top surface of the product to be packaged 200.

[0056] Alternatively, the second buffer structure 50 can also be formed on the outer box 10 at its cavity opening 111. For example, a backing plate, a cushion block, etc. are provided on the outer box 10 at its cavity opening 111, and the provided backing plate or cushion block forms the second buffer structure 50. And the second buffer structure 50 can be flipped like the cover plate of the outer box 10 (including the inner cover 15 and the outer cover 14), or the second buffer structure 50 is connected to the cover plate and flipped together with the cover plate. Before the peripheral sheath 20 and the product to be packaged 200 are put into the installation cavity 11 together, the second buffer structure 50 is flipped outside the cavity opening 111 to avoid hindering the peripheral sheath 20 and the product to be packaged 200 from being put into the installation cavity 11. After the peripheral sheath 20 and the product to be packaged 200 are put into the installation cavity 11, the second buffer structure 50 is then flipped above the product to be packaged 200, so that the top surface of the product to be packaged 200 can be protected and buffered.

[0057] Or, it can also be that a second buffer structure 50 is formed on the peripheral sheath 20, and another buffer structure is formed on the outer box 10. That is, the above two introduced schemes are combined. In this way, the top surface of the product to be packaged 200 can be buffered by the second buffer structure 50 on the peripheral sheath 20, and the top surface of the product to be packaged 200 can also be buffered by the second buffer structure 50 on the outer box 10, achieving multiple protections, and thus the buffering effect is better.

[0058] In summary, it can be understood that since the bottom of the installation cavity 11 is provided with the first buffer structure 40, the cavity opening 111 is provided with the second buffer structure 50, and the peripheral sheath 20 is provided with the second buffer structure 50 on its outer periphery, the two end faces and the outer peripheral face of the product can be buffered, that is, any surface of the product can be buffered and protected, avoiding the product from being broken or damaged due to collision during transportation.

[0059] It can also be understood that since both the outer box body 10 and the peripheral side sheath 20 in the packaging box 100 of the present application are made of cardboard, before packaging the product, the outer box body 10 and the cardboard can be folded and then stored and transported. In this way, the volume of the packaging box 100 during storage and transportation can be reduced, thereby reducing costs. Moreover, compared with the solution of "using a foam cushion as a buffer structure", the packaging box 100 of the present application will not have the situation of "foam particles falling off" that affects the user experience.

[0060] Optionally, in one embodiment, as Figure 2 shown, the peripheral side sheath 20 is in the shape of an annular column with a hollow interior, and the peripheral side sheath 20 has a plurality of side edges 22 and a plurality of side walls 23. A buffer protrusion 21 is provided at each side edge 22, and the buffer protrusion 21 is formed by a part of the edge of the side wall 23 protruding relative to the adjacent side wall 23.

[0061] Specifically, in the Figure 2 shown structural solution, the peripheral side sheath 20 is in the shape of a quadrangular prism. Therefore, the peripheral side sheath 20 has four side edges 22 and four side walls 23. Among them, a buffer protrusion 21 is provided on each side edge 22, and the buffer protrusion 21 on each side edge 22 is formed by a part of the edge of one side wall 23 protruding relative to another side wall 23.

[0062] For example, as Figure 2 shown, the buffer protrusions 21 on each side edge 22 can be divided into a first protrusion 211 and a second protrusion 212 according to different protrusion directions. The two side walls 23 adjacent to the same side edge 22 are respectively a first side wall 231 and a second side wall 232. The first protrusion 211 is located at the edge of the first side wall 231 and is integrally formed with the first side wall 231, and the first protrusion 211 protrudes relative to the surface of the second side wall 232. In this way, a buffer space can be formed at an interval between the second side wall 232 and the inner wall of the installation cavity 11. The second protrusion 212 is located at the edge of the second side wall 232 and is integrally formed with the second side wall 232, and the second protrusion 212 protrudes relative to the surface of the first side wall 231. In this way, a buffer space can be formed at an interval between the first side wall 231 and the inner wall of the installation cavity 11. The buffer protrusions 21 at other side edges 22 can be designed with reference to the above description and will not be introduced in detail here.

[0063] It can be understood that in this embodiment, by making the peripheral sheath 20 in an annular column shape, the user can directly take out the product from the outer box body 10 without having to take out the peripheral sheath 20 first. Further, by arranging the buffer protrusions 21 at the side edges 22, and the buffer protrusions 21 are formed by partial edges on one side wall 23 protruding relative to the other side wall 23, the formation method of the buffer protrusions 21 is relatively simple. When folding the cardboard into the peripheral sheath 20, the buffer protrusions 21 will also be formed naturally. This is not only simple and convenient, but also can ensure that a buffer space is formed at intervals between the outer peripheral surface of the peripheral sheath 20 and the inner peripheral surface of the installation cavity 11.

[0064] It should be noted here that the buffer protrusions 21 on each side edge 22 can protrude relative to the same side wall 23 in one direction, or can protrude relative to different side walls 23 in different directions.

[0065] For example, optionally, in one embodiment, as Figure 3 shown, the peripheral sheath 20 is a hollow quadrangular prism and includes a first side wall 231, a second side wall 232, a third side wall 233, a fourth side wall 234, a first side edge 221, a second side edge 222, a third side edge 223, and a fourth side edge 224. The first side wall 231, the second side wall 232, the third side wall 233, and the fourth side wall 234 are sequentially connected along the circumferential direction of the peripheral sheath 20. The first side edge 221 is located between the first side wall 231 and the second side wall 232. The second side edge 222 is located between the second side wall 232 and the third side wall 233. The third side edge 223 is located between the third side wall 233 and the fourth side wall 234. The fourth side edge 224 is located between the fourth side wall 234 and the first side wall 231.

[0066] Among them, a plurality of buffer protrusions 21 on the first side edge 221 are integrally formed with the first side wall 231 and all protrude relative to the second side wall 232. A plurality of buffer protrusions 21 on the second side edge 222 are integrally formed with the second side wall 232 and all protrude relative to the third side wall 233. A plurality of buffer protrusions 21 on the third side edge 223 are integrally formed with the third side wall 233 and all protrude relative to the fourth side wall 234. A plurality of buffer protrusions 21 on the fourth side edge 224 are integrally formed with the fourth side wall 234 and all protrude relative to the fourth side wall 234. In this way, the four sides of the peripheral sheath 20 all have buffer protrusions 21 arranged in a protruding manner, and thus can buffer the outer peripheral surface of the product 200 to be packaged.

[0067] Another example is, optionally, in one embodiment, as Figure 2 or Figure 4As shown in the figure, there are multiple buffer protrusions 21 at each side edge 22. The multiple buffer protrusions 21 located on the same side edge 22 include multiple first protrusions 211 and multiple second protrusions 212. The multiple first protrusions 211 are connected to one side wall 23 adjacent to the side edge 22, and the multiple second protrusions 212 are connected to the other side wall 23 adjacent to the side edge 22. Moreover, the multiple first protrusions 211 and the multiple second protrusions 212 are alternately arranged along the height direction of the circumferential side sheath 20.

[0068] Specifically, in this embodiment, the multiple buffer protrusions 21 on each side edge 22 protrude from different side walls 23 in different directions respectively. And the multiple buffer protrusions 21 on each side edge 22 can be divided into first protrusions 211 and second protrusions 212 according to the different protruding directions. The first protrusions 211 are integrally formed with one of the side walls 23 and protrude from the other side wall 23. The second protrusions 212 are integrally formed with the other side wall 23 and protrude from the side wall 23 where the first protrusions 211 are located. In this way, buffer protrusions 21 can be provided on both sides of each side wall 23, thereby improving the buffering effect of the circumferential side sheath 20.

[0069] Furthermore, in this embodiment, as Figure 2 shown, the multiple first protrusions 211 and the multiple second protrusions 212 are alternately arranged along the height direction of the circumferential side sheath 20. That is to say, the first protrusions 211 are located between two adjacent second protrusions 212, or the second protrusions 212 are located between two adjacent second protrusions 212. It can be understood that such an arrangement can make the buffering effect of each side wall 23 of the circumferential side sheath 20 more uniform in its height direction, avoiding the situation that the buffer protrusions 21 are concentrated on the upper side resulting in poor buffering effect at the lower side position, or the buffer protrusions 21 are concentrated on the lower side resulting in poor buffering effect at the upper side position, and improving the overall buffering effect.

[0070] Optionally, in an embodiment, please refer to Figure 5 、 Figure 6 and Figure 7 , the circumferential side sheath 20 is formed by folding a first cardboard 24, that is, the circumferential side sheath 20 is formed by folding a single cardboard. In this way, before packaging, the circumferential side sheath 20 can be unfolded into a single cardboard, thereby saving storage and transportation space and reducing costs. In addition, the first cardboard 24 can be a corrugated cardboard, which can further improve the buffering effect of the circumferential side sheath 20.

[0071] Specifically, in this embodiment, the first cardboard 24 includes a plurality of first plate bodies 241 connected in sequence along a straight line direction. A crease portion 242 is formed between two adjacent first plate bodies 241. When folding, the first cardboard 24 is folded along the crease portion 242. After folding, the plurality of first plate bodies 241 respectively form a plurality of side walls 23. Among them, a breaking area 244 is provided at the crease portion 242, and the breaking area 244 extends in a semi-surrounding manner, so that a buffer protrusion 21 can be formed at the side edge 22 of the circumferential sheath 20 after the first cardboard 24 is folded, making the formation of the buffer protrusion 21 simple and convenient.

[0072] Further, in order to make the structure of the first cardboard 24 more stable after being folded into the circumferential sheath 20, a fixing plate body 243 is also provided at one end in the length direction of the first cardboard 24. A crease portion 242 is also provided between the fixing plate body 243 and the first plate body 241 adjacent thereto, and the fixing plate body 243 is used for adhesively fixing with the first plate body 241 at the other end of the first cardboard 24. As Figure 7 shown, after folding, the fixing plate body 243 is parallel to one of the first plate bodies 241, and the fixing plate body 243 and the first plate body 241 corresponding to it in parallel are adhesively fixed, so that the structure of the circumferential sheath 20 can be made more stable and avoid the situation that the circumferential sheath 20 automatically unfolds during use.

[0073] Optionally, in an embodiment, as Figure 7 shown, a buffer convex plate 25 also protrudes from one end of the circumferential sheath 20 close to the cavity opening 111, and the buffer convex plate 25 forms a second buffer structure 50. Specifically, in this embodiment, there are two buffer convex plates 25, and the two buffer convex plates 25 are spaced opposite to each other along the width direction of the circumferential sheath 20, and the buffer convex plate 25 is centrally arranged in the length direction of the circumferential sheath 20. When the circumferential sheath 20 is sleeved outside the product 200 to be packaged, the buffer convex plate 25 protrudes relative to the top surface of the product 200 to be packaged, so that the buffer convex plate 25 can form a buffer for the top surface of the product 200 to be packaged.

[0074] Optionally, in an embodiment, as Figure 7 shown, a picking groove 251 is provided on the buffer convex plate 25, and the picking groove 251 is used for a finger to extend in and pick up the packaged product. Specifically, in this embodiment, a picking groove 251 is recessed on each buffer convex plate 25, the picking groove 251 is a U-shaped groove, and when the circumferential sheath 20 is sleeved outside the product 200 to be packaged, the bottom of the picking groove 251 is lower than the top surface of the product 200 to be packaged, so that it is convenient for the user's hand to extend into the picking groove 251 and pinch the product 200 to be packaged, and then take out the product, without the need for the user to take out the product after taking out the circumferential sheath 20, making it more convenient to take out the product from the packing box 100.

[0075] Optionally, in an embodiment, asFigure 8 , Figure 9 and Figure 10 As shown in Figure 10 , the outer box body 10 is formed by folding the second cardboard 12, that is, the outer box body 10 is formed by folding a single cardboard. In this way, before packaging, the outer box body 10 can be unfolded into a single cardboard, thereby saving storage and transportation space and reducing costs. In addition, the second cardboard 12 can be corrugated cardboard, which can further improve the buffering effect of the outer box body 10.

[0076] Specifically, in this embodiment, the second cardboard 12 includes four peripheral side plate bodies 121, four bottom side plate bodies 122, one outer cover plate body 123, one inner cover plate body 124, and two cushion plate bodies 125 that are sequentially connected along a straight line direction. Please refer to Figure 8 and Figure 10 . After folding, the four peripheral side plate bodies 121 respectively form the four side walls 23 of the outer box body 10. The four bottom side plate bodies 122 are connected to the four peripheral side plate bodies 121 one by one, and after folding, the four bottom plate bodies form the bottom wall of the outer box body 10. The outer cover plate body 123 forms the outer cover 14 of the outer box body 10 after folding, and the inner cover plate body 124 forms the inner cover 15 of the outer box body 10 after folding.

[0077] Please refer to Figure 8 , Figure 9 and Figure 10 . After folding, the two cushion plate bodies 125 respectively form two buffer cushions 13. The two buffer cushions 13 are located on both sides in the length direction of the cavity opening 111. Before the peripheral sheath 20 and the product to be packaged 200 are placed in the installation cavity 11, the buffer cushions 13 are flipped to the outside of the cavity opening 111. After the peripheral sheath 20 and the product to be packaged 200 are placed in the installation cavity 11, the buffer cushions 13 can be flipped into the cavity opening 111 and located above the product to be packaged 200. In this way, the buffer cushions 13 can buffer the top surface of the product, improving the buffering effect.

[0078] Among them, in order to ensure the structural stability of the cushion plate body 125 after being folded into the buffer cushion 13, in this embodiment, as Figure 9 shown, the cushion plate body 125 includes a second plate body 1251 and a third plate body 1252 that are connected to each other. And after being folded into the buffer cushion 13, please refer to Figure 10 . The second plate body 1251 and the third plate body 1252 are spaced relatively. The second plate body 1251 is provided with a first buckle 1253, and the first buckle 1253 is formed by bending a part of the body of the second plate body 1251. The third plate body 1252 is provided with a first card hole 1254, and the first buckle 1253 is clamped in the first card hole 1254 to relatively fix the second plate body 1251 and the third plate body 1252. In this way, it can avoid the situation that the buffer cushion 13 automatically unfolds during use and ensure the structural stability of the buffer cushion 13.

[0079] Optionally, in one embodiment, as Figure 9 shown, on the side of the third plate body 1252 away from the second plate body 1251, a first reinforcing plate body 1255 is further connected. As Figure 10 shown, after the cushion plate body 125 is folded into the buffer cushion 13, the first reinforcing plate body 1255 abuts against the second plate body 1251 and is spaced opposite to the third plate body 1252. It can be understood that by providing the first reinforcing plate body 1255, the number of plate layers included in the buffer cushion 13 can be increased, thereby improving the structural strength and buffering effect of the buffer cushion 13.

[0080] Optionally, in one embodiment, as Figure 1 shown, the packing box 100 further includes a bottom cushion 30. The bottom cushion 30 is arranged at the bottom of the installation cavity 11 and forms a first buffering structure 40. That is to say, the first buffering structure 40 exists independently of the outer box body 10. During packaging, the bottom cushion 30 can be first placed at the bottom of the installation cavity 11, and then the peripheral sheath 20 and the product to be packaged 200 sleeved in the peripheral sheath 20 are placed into the installation cavity 11, so that the peripheral sheath 20 and the product to be packaged 200 are supported on the bottom cushion 30. In this way, the bottom cushion 30 can buffer the bottom surface of the bagged product.

[0081] Specifically, in this embodiment, please refer to Figures 11 to 13 , the bottom cushion 30 is folded from a third cardboard 31. The third cardboard 31 is a corrugated cardboard, and the third cardboard 31 includes a support plate body 311 and cushion table plate bodies 312 connected to both ends of the support plate body 311. The support plate body 311 is used to abut against the bottom of the product to be packaged 200. The cushion table plate bodies 312 are folded relative to the support plate body 311 and are parallel and opposite to the support plate body 311. In this way, the thickness of the bottom cushion 30 at the cushion table plate bodies 312 can be increased, and thus a better buffering effect can be achieved.

[0082] Among them, as Figure 12 shown, a second buckle 3111 is provided on the support plate body 311. As Figure 13 shown, after folding, the cushion table plate bodies 312 are arranged opposite to the support plate body 311, and second card holes 3121 are provided on the cushion table plate bodies 312. The second buckle 3111 is clamped in the second card holes 3121. In this way, the cushion table plate bodies 312 and the support plate body 311 can be relatively fixed, avoiding the situation that the cushion table plate bodies 312 automatically unfold relative to the support plate body 311 during use.

[0083] Optionally, in one embodiment, as Figure 12 shown, on the side of the cushion table plate body 312 away from the support plate body 311, a second reinforcing plate body 313 is further connected. As Figure 13As shown, after the third cardboard 31 is folded, the second reinforcing plate body 313 abuts against the support plate body 311 and is spaced relatively from the cushion table plate body 312. It can be understood that by providing the second reinforcing plate body 313, the number of plate layers of the buffer cushion table at the cushion table plate body 312 can be increased, thereby improving the structural strength and buffer effect of the buffer cushion table.
