[0048] Embodiment one:

[0049] In the packaging structure of embodiment one, the end support module 20 is an integral component.

[0050] As shown in Figure 1 and Figure 2 , the packaging structure provided by embodiment one of the present application comprises a bottom support 10, an end support module 20, a first support part 41, a second support part 42, an outer box 50 and at least two connecting columns 30. The bottom support 10 is provided with a placing groove 11 matched with the bottom of the object to be packaged 100, the end support module 20 is used to limit the head of the object to be packaged 100, the at least two connecting columns 30 are distributed at intervals, the opposite ends of each connecting column 30 are respectively inserted into the bottom support 10 and the end support module 20, the first support part 41 is connected to at least one of the connecting columns 30, the first support part 41 is located between the bottom support 10 and the end support module 20, the second support part 42 is connected to the remaining connecting columns 30, the second support part 42 is located between the bottom support 10 and the end support module 20, and the first support part 41 and the second support part 42 are opposite to each other to sandwich the position between the head and the bottom of the object to be packaged 100.

[0051] The packaging structure is used for packaging the large to-be-packaged object 100, the inner packaging limits and positions the bottom and the head of the to-be-packaged object 100 through the bottom support 10 and the end support module 20 respectively, and the position between the bottom and the head of the to-be-packaged object 100 is clamped and positioned through the relative connection of the first support part 41 and the second support part 42, and the first support part 41 and the second support part 42 are connected with the bottom support 10 and the end support module 20 through the connecting column 30, so that the to-be-packaged object 100 is fully surrounded and packaged, and then the inner packaging and the to-be-packaged object 100 are integrally packaged in the outer box 50, so that the to-be-packaged object 100 cannot shake in the outer box 50 during the transportation of the to-be-packaged object 100, and is completely positioned in the outer box 50. The bottom, the head and the middle part of the to-be-packaged object 100 are positioned by the bottom support 10, the end support module 20, the first support part 41 and the second support part 42 respectively, which can better meet the precision requirements of shockproof and anti-collision of full-surrounding packaging, and the bottom support 10, the end support module 20, the first support part 41 and the second support part 42 are assembled with each other through the connecting column 30, instead of being bonded by glue, so that the packaging structure does not have the defect of cracking, and the staff can quickly complete the packaging of the to-be-packaged object 100, improving the work efficiency.

[0052] In the embodiment one of the application, the bottom support 10 abuts against one end inner wall of the outer box 50, the end support module 20 abuts against the other end inner wall of the outer box 50, and the circumferential side wall of the bottom support 10, the circumferential side wall of the end support module 20 and the circumferential side wall after the relative connection of the first support part 41 and the second support part 42 all abut against the circumferential inner wall of the outer box 50. In this way, the to-be-packaged object 100 can be completely limited and fixed, and the to-be-packaged object 100 cannot shake in the outer box 50 during the transportation of the to-be-packaged object 100.

[0053] As shown in Figure 2 The packaging structure further includes a first auxiliary part 43 and a second auxiliary part 44, the first auxiliary part 43 is connected to the connecting column 30 connected with the first support part 41, and the second auxiliary part 44 is connected to the connecting column 30 connected with the second support part 42. Specifically, the connecting column 30 connected with the first support part 41 passes through the first auxiliary part 43 and is then inserted on the bottom support 10; correspondingly, the connecting column 30 connected with the second support part 42 passes through the second auxiliary part 44 and is then inserted on the bottom support 10. In this way, the first auxiliary part 43 and the second auxiliary part 44 are connected to clamp and position the circumferential side wall close to the bottom of the to-be-packaged object 100, and the circumferential side wall after the relative connection of the first auxiliary part 43 and the second auxiliary part 44 abuts against the circumferential inner wall of the outer box 50, so that the first auxiliary part 43 and the second auxiliary part 44 are used to further position the bottom of the to-be-packaged object 100, so that the to-be-packaged object 100 is more stably positioned in the outer box 50.

[0054] In the first embodiment of the present application, the first auxiliary part 43 is arranged apart from the first support part 41, and the second auxiliary part 44 is arranged apart from the second support part 42, that is, the volume (height) of the first auxiliary part 43 and the second auxiliary part 44 does not need to be too large, and only needs to be able to clamp and position the circumferential side wall of the bottom of the to-be-packaged object 100. Alternatively, in other embodiments of the first embodiment of the present application, the first auxiliary part 43 can extend to the first support part 41 and be connected to the first support part 41, and the second auxiliary part 44 can extend to the second support part 42 and be connected to the second support part 42, so as to completely wrap the to-be-packaged object 100, and realize overall packaging protection.

[0055] As shown in Figure 2 In order to more effectively utilize the end support module 20 for packaging, the side of the end support module 20 away from the bottom support 10 is provided with a containing groove 23 for placing the adaptive accessory 101 of the to-be-packaged object 100. In this way, the effective packaging volume of the end support module 20 is effectively utilized, and more adaptive accessories 101 of the to-be-packaged object 100 can be packaged without increasing the space volume of the outer box 50.

[0056] In the packaging structure of the first embodiment of the present application, the number of connecting columns 30 is even, half of the connecting columns 30 are connected to the first support part 41, and the other half of the connecting columns 30 are connected to the second support part 42, so as to effectively improve the connection strength between the bottom support 10, the first support part 41 and the end support module 20, and effectively improve the connection strength between the bottom support 10, the second support part 42 and the end support module 20. Furthermore, the connecting columns 30 connected to the first support part 41 and the connecting columns 30 connected to the second support part 42 are symmetrically distributed with respect to the axis of the to-be-packaged object 100. Further, when the number of connecting columns 30 connected to the first support part 41 is greater than or equal to 3, the distance between adjacent two connecting columns 30 is equal; when the number of connecting columns 30 connected to the second support part 42 is greater than or equal to 3, the distance between adjacent two connecting columns 30 is equal. As shown in Figure 5 In the first embodiment of the present application, the number of connecting columns 30 is 4.

[0057] As shown in Figures 3 to 5As shown, each connecting column 30 is provided with a first stop portion 31 and a second stop portion 32, which are arranged along the axial direction of the connecting column 30. When the first support portion 41, the second support portion 42, the first auxiliary portion 43, the second auxiliary portion 44 and the end support module 20 are assembled to the connecting column 30, the end of the first stop portion 31 away from the second stop portion 32 abuts against the end support module 20, the end of the second stop portion 32 towards the first stop portion 31 abuts against the first support portion 41 or the second support portion 42, and the end of the second stop portion 32 away from the first stop portion 31 abuts against the first auxiliary portion 43 or the second auxiliary portion 44. In the first embodiment, a through hole is formed on the end support module 20 corresponding to each connecting column 30, and the end of each connecting column 30 is correspondingly inserted into the through hole. Therefore, when the connecting column 30 is in the vertical state, each first stop portion 31 can block the end support module 20 from sliding along the axial direction of the connecting column 30 towards the first support portion 41 or the second support portion 42. Correspondingly, each second stop portion 32 of the connecting column 30 connected with the first support portion 41 blocks the first support portion 41 from sliding towards the first auxiliary portion 43, and each second stop portion 32 of the connecting column 30 connected with the second support portion 42 blocks the second support portion 42 from sliding towards the second auxiliary portion 44.

[0058] As Figure 1As shown, each connecting column 30 is folded and formed by corrugated paperboard. The corrugated paperboard is provided with a first crease 301, a second crease 302, a third crease 303 and a fourth crease 304 in sequence along a direction perpendicular to an axis of the connecting column 30, the first crease 301 and the second crease 302 are parallel to the axis of the connecting column 30, a width of a region between the first crease 301 and the second crease 302 is greater than a width of a region between the third crease 303 and the fourth crease 304, a fifth crease 305 is provided between the first crease 301 and the second crease 302 and is parallel to the axis of the connecting column 30, and a first cut 306, a second cut 307, a third cut 308 and a fourth cut 309 are provided in sequence along the axis of the connecting column 30 in the region between the first crease 301 and the second crease 302. In the process of folding and forming the connecting column 30 by the corrugated paperboard, the corrugated paperboard is bent by the first crease 301, the second crease 302, the third crease 303 and the fourth crease 304 and connected at the head and tail, and at this time, the region between the first crease 301 and the second crease 302 is recessed along the fifth crease 305 towards the region between the third crease 303 and the fourth crease 304. Then, the region between the first cut 306 and the second cut 307 is protruded by the first crease 301, the second crease 302 and the fifth crease 305 towards a direction away from the region between the third crease 303 and the fourth crease 304 to form the first stop 31, the region between the third cut 308 and the fourth cut 309 is protruded by the first crease 301, the second crease 302 and the fifth crease 305 towards a direction away from the region between the third crease 303 and the fourth crease 304 to form the second stop 32, and the other regions between the first crease 301 and the second crease 302 are all recessed along the fifth crease 305 towards the region between the third crease 303 and the fourth crease 304, so that the folding and forming of the connecting column 30 is completed. In order to make the folding and forming of the connecting column 30 more stable and not loose, therefore, the region between one side of the corrugated paperboard along the axis of the connecting column 30 and the first crease 301 and the region between the other side of the corrugated paperboard along the axis of the connecting column 30 and the fourth crease 304 are overlapped with each other and fixed by adhesive (or by a buckle).

[0059] As shown in the figure, Figure 6 The outer box 50 includes a bottom cover 51, a surrounding wall 52 and a top cover 53, and the combined outer box 50 is convenient for workers to pack. The bottom cover 51 and the top cover 53 are respectively covered on both ends of the surrounding wall 52, the bottom support 10 abuts against the bottom cover 51, the end support module 20 abuts against the top cover 53, and the circumferential side wall of the bottom support 10, the circumferential side wall of the end support module 20, the circumferential side wall after the abutment of the first support part 41 and the second support part 42 all abut against the circumferential inner wall of the surrounding wall 52.

[0060] And, the bottom support 10, the first support part 41, the second support part 42, the first auxiliary part 43, the second auxiliary part 44 and the end support module 20 are all made of foam, pearl wool or other recyclable materials. In this way, the bottom support 10, the first support part 41, the second support part 42, the first auxiliary part 43, the second auxiliary part 44 and the end support module 20 are connected and assembled by the connecting columns 30 of corrugated paperboard. When the packaging structure needs to be disassembled, the two different materials can be classified and recycled conveniently and quickly by extracting the connecting columns 30.
