[0041] As shown in Figures 1-9 , the packaging box provided by the embodiments of the present application comprises a side plate 1, a bottom plate 4 and a fold edge connecting portion 2.

[0042] Among them, the side plate 1 is at least two, and is distributed along the circumference of the packaging box. All side plates 1 are connected with the bottom plate 4.

[0043] The side plate 1 has three side edges 12, two side edges 12 are connected with the adjacent side plate 1 through the corresponding fold edge connecting portion 2 respectively, and the other side edge 12 is connected with the bottom plate 4 through the corresponding fold edge connecting portion 2; the corresponding fold edge connecting portion 2 of at least two side edges 12 of at least one side plate 1 has a tearable portion 21, so that the above-mentioned at least two side edges 12 and the corresponding fold edge connecting portion 2 are separated.

[0044] As shown in Figure 4 , Figure 8 and Figure 9 , the three side edges 12 of the side plate 1 are respectively a first side edge 12a, a second side edge 12b and a third side edge 12c; wherein the first side edge 12a is located at one side of the side plate 1, the second side edge 12b is located at the other side of the side plate 1, and the third side edge 12c is located at the bottom end of the side plate 1. The fold edge connecting portion 2 corresponding to the first side edge 12a can be called the first fold edge connecting portion 2a, the fold edge connecting portion 2 corresponding to the second side edge 12b can also be called the first fold edge connecting portion 2a, and the fold edge connecting portion 2 corresponding to the third side edge 12c can be called the second fold edge connecting portion 2b. The first side edge 12a and the adjacent side plate 1 are connected through the first fold edge connecting portion 2a, the second side edge 12b and the adjacent side plate 1 are connected through the first fold edge connecting portion 2a, and the third side edge 12c and the bottom plate 4 are connected through the second fold edge connecting portion 2b.

[0045] The corresponding fold edge connecting portion 2 of at least two side edges 12 of at least one side plate 1 has a tearable portion 21, so that the above-mentioned at least two side edges 12 and the corresponding fold edge connecting portion 2 are separated, there are three structures, which will be described below with one side plate 1 as an example.

[0046] The first structure is shown in Figures 1-8As shown in the drawings, the at least two side edges 12 include two side edges 12 connected with the adjacent side panel 1. It can be understood that the at least two side edges 12 include a first side edge 12a and a second side edge 12b. In this case, the easy-tear portion 21 is a first easy-tear portion 21a, which is located at the first fold edge connecting portion 2a and extends from the top end of the side panel 1 to the bottom end of the side panel 1.

[0047] It should be noted that the top end and the bottom end of the side panel 1 are distributed along the height direction of the packaging box, and the height direction of the packaging box can be understood as the height direction of the side panel 1. The first easy-tear portion 21a extends from the top end of the side panel 1 to the bottom end of the side panel 1, which can be understood as that the length direction of the first easy-tear portion 21a is the height direction of the side panel 1, the top end of the first easy-tear portion 21a is flush with the top end of the side panel 1, and the bottom end of the first easy-tear portion 21a can be flush with or not flush with the bottom end of the side panel 1. In order to facilitate the removal of the packaging box and the taking out of the equipment, the bottom end of the first easy-tear portion 21a can be flush with the bottom end of the side panel 1, so that the bottom end of the first easy-tear portion 21a extends to the bottom end of the side panel 1.

[0048] By using the above first structure, the first side edge 12a and the second side edge 12b can be separated from the corresponding fold edge connecting portion 2, so that the side panel 1 can be separated from other side panels 1, and the separated side panel 1 can be turned over. The turned-over side panel 1 is parallel or approximately parallel to the bottom panel 4, so that the opening of the side panel 1 is completed; moreover, the side panel 1 can be separated from other side panels 1 by tearing along the first easy-tear portion 21a, which simplifies the operation.

[0049] The second structure is shown in the drawings. Figure 9 As shown in the drawings, the at least two side edges 12 include one side edge 12 connected with the adjacent side panel 1 and one side edge 12 connected with the bottom panel 4. It can be understood that the at least two side edges 12 include one of the first side edge 12a and the second side edge 12b and a third side edge 12c. In this case, the easy-tear portion 21 includes the first easy-tear portion 21a and the second easy-tear portion 21b, the first easy-tear portion 21a is located at the first fold edge connecting portion 2a, the second easy-tear portion 21b is located at the second fold edge connecting portion 2b, the first easy-tear portion 21a extends from the top end of the side panel 1 to the bottom end of the side panel 1, the second easy-tear portion 21b is connected with the bottom end of the first easy-tear portion 21a, and the second easy-tear portion 21b extends from the first easy-tear portion 21a in a direction away from the first easy-tear portion 21a. For example, the first easy-tear portion 21a is connected with the first side edge 12a, and then the second easy-tear portion 21b extends from the first side edge 12a to the second side edge 12b; or the first easy-tear portion 21a is connected with the second side edge 12b, and then the second easy-tear portion 21b extends from the second side edge 12b to the first side edge 12a.

[0050] With the second structure, the first side edge 12a or the second side edge 12b and the corresponding first fold edge connecting part 2a can be separated, and the third side edge 12c and the corresponding second fold edge connecting part 2b can be separated, so that the side plate 1 can be separated from the adjacent side plate 1 and the bottom plate 4, the separated side plate 1 is turned over, and the turned-over side plate 1 is parallel or approximately parallel to the other side plate 1, so that the opening of the side plate 1 is completed. The specific method for separating the side plate 1 is that the first easy-tear part 21a is pulled and torn, and then the second easy-tear part 21b is pulled and torn, so that the side plate 1 can be separated from the adjacent side plate 1 and the bottom plate 4.

[0051] The third structure is that the at least two side edges 12 include three side edges 12. It can be understood that the at least two side edges 12 include a first side edge 12a, a second side edge 12b and a third side edge 12c. In this case, the easy-tear part 21 includes a first easy-tear part 21a and a second easy-tear part 21b. The first easy-tear part 21a and the second easy-tear part 21b are described above.

[0052] With the third structure, the side plate 1 can be opened in the above two ways, and a third way of combining the above two ways is also provided. With the third way, the side plate 1 can be completely separated from other parts of the packaging box. Since the third structure has three ways of opening the side plate 1, the way of opening the side plate 1 can be selected according to actual conditions, and the flexibility of disassembling the packaging box is improved.

[0053] In actual conditions, the packaging box also includes a cover plate 3, the side plate 1 connects the cover plate 3 and the bottom plate 4, and the fold edge connecting part 2 also connects the cover plate 3 and the bottom plate 4. The top end of the side plate 1 is connected to the cover plate 3, and the bottom end of the side plate 1 is connected to the bottom plate 4; the top end of the first fold edge connecting part 2a is connected to the cover plate 3, and the bottom end of the first fold edge connecting part 2a is connected to the bottom plate 4.

[0054] The number of cover plates 3 and bottom plates 4 can be selected according to actual conditions. For example, in order to facilitate the formation of the packaging box, the cover plate 3 and the side plate 1 can be one-to-one, and the bottom plate 4 and the side plate 1 can be one-to-one. In this case, the cover plate 3 and the bottom plate 4 can be called a rocker cover. The third side edge 12c and the adjacent bottom plate 4 are connected by the second fold edge connecting part 2b.

[0055] The disassembly method of the packaging box is that the installer opens the cover plate 3 of the packaging box, tears along the easy-tear part 21, separates the side plate 1, turns over the separated side plate 1, opens the side plate 1, removes the restriction of the side plate 1 on the equipment (not shown in the figure), and pulls out the equipment inside the packaging box, thereby completing the disassembly of the packaging box.

[0056] As can be seen from the above disassembly method, compared with the existing violent disassembly, the packaging box does not need to be stepped on multiple times, and the efficiency of disassembling the packaging box is effectively improved.

[0057] From the above disassembly method, in the disassembly process, the touch to the internal equipment of the packaging box is reduced, thereby reducing the probability of scratching and damaging the equipment due to disassembly of the packaging box; the disassembly of the packaging box can optimize the operation of violent unpacking, facilitate the standardization of the disassembly of the packaging box, and also improve the installation experience of the installer.

[0058] In the packaging box, the restriction of the side plate 1 on the equipment can be removed, facilitating the pulling out of the equipment inside the packaging box, compared with lifting the equipment inside the packaging box from bottom to top, the equipment does not need to be lifted, effectively simplifying the taking out of the equipment, and correspondingly, improving the efficiency of disassembling the packaging box.

[0059] In the case that the product information (at least one of text and two-dimensional code) such as product parameters is marked on the side of the equipment, the side plate 1 corresponding to the product information can be separated (the side plate 1 is separated from the two adjacent side plates 1, or the side plate 1 is separated from the adjacent side plate 1 and the side plate is separated from the adjacent bottom plate 4), and then the side plate 1 corresponding to the product information is turned over, so that the product information is exposed, facilitating the installer to obtain the product information of the equipment.

[0060] In the packaging box, since the side plate 1 can be separated, the side plate 1 can be turned over to be parallel or approximately parallel to the bottom plate 4, or the side plate 1 can be turned over to be parallel or approximately parallel to another side plate 1, facilitating subsequent arrangement and storage of the packaging box.

[0061] The packaging box can package equipment with large volume and large weight, and can also package equipment with small volume and small weight. The packaging box can package power electronic equipment such as inverters, and can also package other equipment. The equipment packaged by the packaging box is not limited in the embodiments of the present application.

[0062] In the packaging box, the edge connection part 2 includes a connected edge 22 and a connection part 23, and the easy-to-tear part 21 is located on the side of the connection part 23 away from the edge 22. In this way, the easy-to-tear part 21 deviates from the edge 22, reducing the influence of the easy-to-tear part 21 on the strength of the edge 22, thereby reducing the influence of the easy-to-tear part 21 on the overall strength of the packaging box, and facilitating to ensure the overall strength of the packaging box. Figures 1-4 、 Figure 9 As shown in the figure, the connection part 23 is located on one side of the edge 22. In this case, the side plate 1 on one side of the edge connection part 2 is connected with the corresponding easy-to-tear part 21. In this way, the structure of the edge connection part 2 is simplified, thereby simplifying the structure of the entire packaging box and reducing the cost of the entire packaging box.

[0063] As shown in the figure, the connection part 23 is located on one side of the edge 22. In this case, the side plate 1 on one side of the edge connection part 2 is connected with the corresponding easy-to-tear part 21. In this way, the structure of the edge connection part 2 is simplified, thereby simplifying the structure of the entire packaging box and reducing the cost of the entire packaging box. Figures 6-8As shown, the connecting portion 23 is located on both sides of the folded edge 22, and the easy-tear portion 21 is located on the side of each connecting portion 23 away from the folded edge 22. In this case, the side panels 1 on both sides of the folded edge connecting portion 2 are connected to the corresponding easy-tear portion 21. This facilitates the separation of adjacent side panels 1 and improves the efficiency of unpacking the packaging box.

[0064] In practice, the folded edge connecting part 2 can also be other structures. For example, the folded edge connecting part 2 includes a folded edge 22, and the easy-tear part 21 is provided at the folded edge 22.

[0065] It should be noted that the first folded edge connecting part 2a can be the structure of the folded edge connecting part 2 described above, and the second folded edge connecting part 2b can also be the structure of the folded edge connecting part 2 described above.

[0066] To facilitate the movement of the packaging box, the packaging box can be equipped with a handle. To facilitate the formation of the handle, the side panel 1 is provided with a handle tear line 11. The handle can be obtained by tearing along the handle tear line 11. The handle is in the shape of a hole.

[0067] The structure of the easy-tear part 21 will be specifically described below through two embodiments.

[0068] Example 1 of this application

[0069] like Figures 1-4 As shown in Embodiment 1 of this application, the packaging box includes: a cover plate 3, a bottom plate 4, a side plate 1, and a first folded edge connecting part 2a.

[0070] For an explanation of the cover plate 3, bottom plate 4, side plate 1 and first folded edge connecting part 2a, please refer to the previous text.

[0071] The packaging box is rectangular in shape, with four side panels 1, and four cover panels 3 and four bottom panels 4. There are four first folded edge connecting parts 2a, so that each pair of adjacent side panels 1 is connected by a first folded edge connecting part 2a.

[0072] Of course, there can be two or three first folded edge connecting parts 2a. When there are two first folded edge connecting parts 2a, there are two side plates 1, each side plate 1 is L-shaped, or one side plate 1 is flat and the other side plate 1 is U-shaped.

[0073] In practice, the packaging box can also be of other shapes, and the number of the cover plate 3, bottom plate 4, side plate 1 and first folded edge connecting part 2a can also be other. This application does not limit this in Embodiment 1.

[0074] In the first folded edge connecting portion 2a, the connecting portion 23 is located on one side of the folded edge 22. Of course, the connecting portion 23 can also be located on both sides of the folded edge 22, and is not limited to this. Figures 1-4 The structure shown.

[0075] likeFigure 5 As shown, the side plate 1 can be a corrugated board 7, which includes a carton board 71 and a corrugated paper 72. The carton board 71 is at least two layers, and the corrugated paper 72 is at least one layer. The two adjacent layers of the carton board 71 have one layer of the corrugated paper 72. The corrugated paper 72 is curved, which can be understood as that the corrugated paper 72 has alternating protrusions and grooves.

[0076] In order to facilitate tearing, the protrusions and grooves of the corrugated paper 72 can be alternately distributed along the height direction of the side plate 1. In this way, the tearing from top to bottom is along the corrugated paper, which is more conducive to tearing and also helps to reduce the cost of the packaging box.

[0077] The first easy-tear part 21a of the first fold edge connecting part 2a will be described below.

[0078] Continuing to refer to Figures 1-4 , the first easy-tear part 21a is located on the inner side of the first fold edge connecting part 2a, and there is a set distance between the first easy-tear part 21a and the outer side of the first fold edge connecting part 2a. The inner side of the first fold edge connecting part 2a faces the cavity of the packaging box, and the outer side of the first fold edge connecting part 2a faces away from the cavity of the packaging box. In this way, the first easy-tear part 21a is prevented from being exposed on the outer surface of the packaging box, improving the appearance of the packaging box. The breaking resistance and tearing experience of the packaging box during tearing are also improved.

[0079] For example, the side plate 1 is an N-layer corrugated board, and the first easy-tear part 21a penetrates the n-layer structure of the side plate 1 from the inner side of the side plate 1. N > n, and N and n are positive integers. For example, N = 5 and n = 3. Of course, N can also be three, seven, eleven, etc., and the value of n is adaptively adjusted according to the value of N.

[0080] In the embodiment of the application, the first easy-tear part 21a includes an easy-tear strip 212, which extends from the top end of the side plate 1 to the bottom end of the side plate 1. The top end of the easy-tear strip 212 is flush with the top end of the side plate 1, and the bottom end of the easy-tear strip 212 can be flush with or not flush with the bottom end of the side plate 1. In order to facilitate separation of the side plate 1, the bottom end of the easy-tear strip 212 can be flush with the bottom end of the side plate 1.

[0081] During the process of disassembling the packaging box, tearing the easy-tear strip 212 can achieve separation of adjacent side plates 1, without the need to tear the side plate 1, thereby simplifying the tearing operation and thus simplifying the disassembly of the packaging box.

[0082] The above-mentioned easy-tear strip 212 is formed by two easy-tear lines 211, which can be score lines, broken-point die-cut lines or other types. For example, the easy-tear line 211 is a toothed cutter line or other types of broken-point die-cut line. The type of the easy-tear line 211 and the easy-tear strip 212 is not limited in the embodiment of the application.

[0083] In the above structure, in order to facilitate the tearing and simplify the structure of the packaging box, the connecting part 23 is located on one side of the folding edge 22 in the first folding edge connecting part 2a, and the easy-to-tear strip 212 and the connecting part 23 are located on the same side of the folding edge 22.

[0084] In order to facilitate the tearing and improve the strength of the easy-to-tear strip 212, the above-mentioned easy-to-tear strip 212 is fixed with a tearing strip 24. For example, the tearing strip 24 is bonded on the easy-to-tear strip 212, or the tearing strip 24 and the easy-to-tear strip 212 are fixedly connected through a clamping structure or a connecting nail structure.

[0085] The tearing strip 24 can be a fiber tearing strip, a plastic tearing strip or other types. Since the strength of the fiber tearing strip is better than that of the plastic tearing strip, in order to improve the strength of the tearing strip 24, the tearing strip 24 can be a fiber tearing strip, which reduces the probability of tearing the tearing strip 24 and reduces the probability of tearing the tearing strip 24.

[0086] The tearing strip 24 can be located inside the packaging box or outside the packaging box. In order to improve the appearance of the packaging box, the tearing strip 24 can be located inside the packaging box, which can be understood as: the tearing strip 24 is located on the inner side of the easy-to-tear strip 212, and the inner side of the easy-to-tear strip 212 faces the cavity of the packaging box.

[0087] The tearing strip 24 can be flush with the easy-to-tear strip 212, which can be understood as: the top end of the tearing strip 24 and the top end of the easy-to-tear strip 212 are flush, and the bottom end of the tearing strip 24 and the bottom end of the easy-to-tear strip 212 are flush.

[0088] Of course, the tearing strip 24 can also be arranged not flush with the easy-to-tear strip 212. For example, the top end of the tearing strip 24 and the top end of the easy-to-tear strip 212 are not flush, and / or the bottom end of the tearing strip 24 and the bottom end of the easy-to-tear strip 212 are not flush.

[0089] In order to effectively improve the strength of the easy-to-tear strip 212, the top end of the tearing strip 24 and the top end of the easy-to-tear strip 212 are flush, so that the top end of the tearing strip 24 is lower than the top end of the easy-to-tear strip 212, which facilitates the tearing of the above-mentioned tearing strip 24 and easy-to-tear strip 212, and can also avoid the situation of mistaken tearing.

[0090] In order to effectively improve the strength of the easy-to-tear strip 212, the tearing strip 24 can also extend to the bottom end of the easy-to-tear strip 212, which can be understood as: the bottom end of the tearing strip 24 and the bottom end of the easy-to-tear strip 212 are flush. The top end of the tearing strip 24 and the top end of the easy-to-tear strip 212 can be flush or not flush.

[0091] In order to facilitate the tearing, the top end of the tear strip 24 can extend to the cover plate 3. In this case, the top end of the tear strip 24 is more likely to be touched and the tearing by mistake is more likely to occur. In order to solve this problem, the cover plate 3 is provided with a cover plate easy tearing line 31, two adjacent edges of the cover plate 3 and the cover plate easy tearing line 31 form a cover plate easy tearing area 32, and the tear strip 24 extends to the cover plate easy tearing area 32.

[0092] The tear strip 24 can be fixed to the cover plate easy tearing area 32 or in the cover plate easy tearing area 32. In order to facilitate the tearing and hide the tear strip 24, the tear strip 24 can be fixed to the cover plate easy tearing area 32. The fixing mode of the tear strip 24 can refer to the fixing mode of the tear strip 24 to the easy tearing strip 212, which will not be described here.

[0093] The size and shape of the cover plate easy tearing area 32 and the size and shape of the cover plate easy tearing line 31 are designed according to the size and shape of the tear strip 24. For example, the cover plate easy tearing line 31 is L-shaped, and the cover plate easy tearing area 32 is quadrangular.

[0094] In order to facilitate the tearing, the cover plate easy tearing line 31 can extend from the inner side of the cover plate 3 to the outer side of the cover plate 3. It can be understood that the inner side of the cover plate 3 faces the cavity of the packaging box, and the outer side of the cover plate 3 faces away from the cavity of the packaging box. Of course, the cover plate easy tearing line 31 can also be located on the inner side of the cover plate 3 and not extend to the outer side of the cover plate 3, or the cover plate easy tearing line 31 can be located on the outer side of the cover plate 3 and not extend to the inner side of the cover plate 3.

[0095] The type of the cover plate easy tearing line 31 can refer to the easy tearing line 211, which will not be described here.

[0096] As shown in Figure 4 The method for removing the packaging box comprises the following steps:

[0097] Opening the cover plate 3 of the packaging box;

[0098] Tearing the cover plate easy tearing area 32 along the cover plate easy tearing line 31 and moving the tear strip 24 of the cover plate easy tearing area 32, tearing the easy tearing strip 212 through the tear strip 24, and tearing off the easy tearing strip 212; wherein, after tearing off the easy tearing strip 212, a first opening 5 is formed; after tearing off the cover plate easy tearing area 32, a second opening 6 is formed; and the two side plates 1 on both sides of the first opening 5 are separated;

[0099] Then, another cover plate easy tearing area 32 and another easy tearing strip 212 are torn according to the above steps, so that the two sides of the two side plates 1 are separated;

[0100] Turning over the two separated side plates 1, pulling out the equipment in the packaging box, and completing the removal of the packaging box.

[0101] In the above method for disassembling the packaging box, only one side plate 1 can be separated and turned over, or three side plates 1 can be separated, and it is not limited to Figure 4 two side plates 1 are separated and turned over.

[0102] In the above method for disassembling the packaging box, a paper holder or other protective member can be arranged between the device and the packaging box. In this case, after the separated side plate 1 is turned over, the protective member needs to be removed before the device is pulled out.

[0103] Embodiment two of the present application

[0104] As Figures 6-8 shown in the embodiment two of the present application, the packaging box comprises a cover plate 3, a bottom plate 4, a side plate 1 and a first fold edge connecting part 2a.

[0105] The cover plate 3, the bottom plate 4, the side plate 1 and the first fold edge connecting part 2a are described above.

[0106] The main difference between the packaging box provided by the embodiment two of the present application and the packaging box provided by the embodiment one of the present application is that the specific structure of the first tearable part 21a is different.

[0107] In the embodiment two of the present application, the first tearable part 21a comprises a tearable line 211, and the tearable line 211 extends from the top end of the side plate 1 to the bottom end of the side plate 1. The top end of the tearable line 211 is flush with the top end of the side plate 1, and the bottom end of the tearable line 211 can be flush with the bottom end of the side plate 1 or not flush with the bottom end of the side plate 1. In order to facilitate the separation of the side plate 1, the bottom end of the tearable line 211 can be flush with the bottom end of the side plate 1.

[0108] The type of the tearable line 211 can be referred to the above, which will not be described here.

[0109] In the above structure, in order to facilitate the tearing of the side plate 1, the connecting part 23 in the fold edge connecting part 2 is located on the same side of the fold edge 22, and the tearable strip 212 is also located on the same side of the fold edge 22.

[0110] In the process of disassembling the packaging box, the cover plate 3 or the side plate 1 needs to be acted on to tear the side plate 1 along the tearable line 211. Therefore, after the side plate 1 is torn, the side plate 1 can be directly turned over, which simplifies the operation steps and is conducive to improving the efficiency of disassembling the packaging box. At the same time, the structure of the first tearable part 21a is relatively simple, which also simplifies the structure of the entire packaging box and reduces the cost of the packaging box.

[0111] In the second embodiment of the present application, the connecting part 23 is two, which is distributed on both sides of the folding edge 22, and the first easy-to-tear part 21a is also two, which is distributed on both sides of the folding edge 22. Of course, the connecting part 23 can also be one, which is located on one side of the folding edge 22, and the easy-to-tear part 21 is also located on one side of the folding edge 22.

[0112] In the second embodiment of the present application, the packaging box is cuboid, the side plate 1 is four, the cover plate 3 and the bottom plate 4 are also four. The first folding edge connecting part 2a is four, so that the first folding edge connecting part 2a is connected between the two adjacent side plates 1. The two sides of each side plate 1 are directly connected with the easy-to-tear line 211, which facilitates tearing the side plate 1.

[0113] Of course, the first folding edge connecting part 2a can also be two or three. In the case of two first folding edge connecting parts 2a, the side plate 1 is two, and each side plate 1 is L-shaped, or one side plate 1 is flat and the other side plate 1 is U-shaped.

[0114] In actual situations, the packaging box can also have other shapes, and the number of cover plates 3, bottom plates 4, side plates 1 and folding edge connecting parts 2 can also be other, which are not limited in the first embodiment of the present application.

[0115] As shown in the first embodiment of the present application, the method for disassembling the packaging box comprises the following steps: Figure 8 Opening the cover plate 3 of the packaging box;

[0116] Tearing the side plate 1 with the cover plate 3 along the easy-to-tear line 211, so that the two sides of the side plate 1 are separated, and the side plate 1 is turned over;

[0117] Tearing the other side plate 1 with the cover plate 3 along the easy-to-tear line 211, so that the two sides of the side plate 1 are separated, and the side plate 1 is turned over;

[0118] Pulling out the equipment in the packaging box, and completing the disassembly of the packaging box.

[0119] In the above method for disassembling the packaging box, only one side plate 1 can be separated and turned over, or three side plates 1 can be separated and turned over, and it is not limited to the two side plates 1 being separated and turned over as shown in the first embodiment of the present application.

[0120] Figure 8 In the above method for disassembling the packaging box, a paper holder or other protective part can also be arranged between the equipment and the packaging box. In this case, after turning over the separated side plate 1, the protective part needs to be removed before pulling out the equipment.

[0121] In the above method for disassembling the packaging box, a paper holder or other protective part can also be arranged between the equipment and the packaging box. In this case, after turning over the separated side plate 1, the protective part needs to be removed before pulling out the equipment.

[0122] ​It should be noted that after the side panel 1 is separated and flipped, the folded edge connecting part 2 remains vertical. Since the folded edge connecting part 2 is small, it can also be bent to a horizontal or approximately horizontal position.

[0123] Example 3 of this application

[0124] like Figures 6-8 As shown in Embodiment 3 of this application, the packaging box includes: a cover plate 3, a bottom plate 4, a side plate 1, a first folded edge connecting part 2a, and a second folded edge connecting part 2b.
