In a specific embodiment, first, the first connecting member 51 on the second covering cloth 22 is connected to the first connecting member 51 on the third covering cloth 23, so that one side of the outer surface of the second covering cloth 22 is folded onto the third covering cloth 23; since the outer surface of the second covering cloth 22 is folded onto the third covering cloth 23, the inner surface of the second covering cloth 22 is turned over, and then the first connecting member 51 on the fourth covering cloth 24 is connected to the third connecting member 53 on the inner surface of the second covering cloth 22, so that one side of the outer surface of the fourth covering cloth 24 can be folded onto the inner surface side of the second covering cloth 22. Further, by adhesively connecting the first folding connecting member 54 and the second folding connecting member 55 at both ends of the fourth covering cloth 24 and the first covering cloth 21, the fourth covering cloth 24 and the first covering cloth 21 can be folded toward the top covering cloth 11 respectively. Further, when the remaining covering cloths have all been folded above the top covering cloth 11, the already folded covering cloth can be wound through the auxiliary winding strap 56 connected to the top covering cloth 11, and the packaging device can be fixed and tied through the auxiliary connecting member on the auxiliary winding strap 56. Through winding and storage, the space occupied by storing the covering cloth can be effectively reduced, the overall reuse rate of the packaging device can be effectively improved, and the environmental pollution caused by disposable packaging can be reduced.

[0068] In some specific embodiments, fixing members 57 are provided on the first covering cloth 21 and / or the third covering cloth 23. At least two multi-faceted fixing straps 58 extend from the second covering cloth 22 and / or the fourth covering cloth 24; when a receiving space for accommodating articles is formed between the covering cloths, a part of the multi-faceted fixing straps 58 extend from the second covering cloth 22 and / or the fourth covering cloth 24, pass through the bottom of the external tray corresponding to the corresponding top covering cloth 11, and are fixedly connected to the fixing members 57 on the first covering cloth 21. In a specific embodiment, since the multi-faceted fixing straps 58 need to be inclined for fixing between different surfaces, the installation direction of the fixing members 57 on the first covering cloth 21 and / or the third covering cloth 23 also forms an inclination angle with the side edge at the end away from the top covering cloth 11, so as to better cooperate with the extension angle of the multi-faceted fixing straps 58.

[0069] In practical applications, a storage connecting member is also provided on the second covering cloth 22 and / or the fourth covering cloth 24. This storage connecting member can be detachably connected to the multi-faceted fixing straps 58, so that when the multi-faceted fixing straps 58 are not in use, the multi-faceted fixing straps 58 can be connected to the storage connecting member for storage, to prevent the multi-faceted fixing straps 58 from being soiled by falling to the ground or being involved in an external mechanism or being entangled with an external object. Another part of the multi-faceted fixing straps 58 extend from the second covering cloth 22 and / or the fourth covering cloth 24 when a receiving space for accommodating articles is formed between the covering cloths, pass through the bottom of the external tray corresponding to the corresponding top covering cloth 11, and are fixedly connected to the fixing members 57 on the third covering cloth 23.

[0070] In some specific embodiments, the second covering cloth 22 and the fourth covering cloth 24 are symmetrically arranged relative to the third covering cloth 23, and the first connection structure 43 and the second connection mechanism have the same length. The area of the second covering cloth 22 and the area of the fourth covering cloth 24 may be the same.

[0071] In a specific embodiment, the second side 32 and the third side 33 of the second covering cloth 22 are arc-connected to form a rounded corner. The first covering cloth 21, the top covering cloth 11, and the third covering cloth 23 can form a whole.

[0072] In a specific embodiment, the top covering cloth 11, the first covering cloth 21, the second covering cloth 22, the third covering cloth 23, and the fourth covering cloth 24 are all rectangular. The area of the first covering cloth 21 is the same as that of the third covering cloth 23, and the area of the second covering cloth 22 is the same as that of the fourth covering cloth 24. Therefore, the accommodating space formed by the connection or detachable connection between the covering cloths is a space in the shape of a cube or approximately a cube structure.

[0073] In practical applications, goods are often packaged in boxes with the same cubic structure. When multiple boxes of goods need to be transported, the goods can be stacked to form one or more stacks of goods groups with a volume less than or equal to the volume of the accommodating space of a packaging device. The goods group is placed on an external tray. At this time, the packaging device can be used to cover and package the outer surface of the goods group, so that the top of the goods group corresponds to the top covering cloth 11, and each side of the goods group corresponds to the other covering cloths. Further, the goods group is placed in the accommodating space formed by each covering cloth, and by adjusting the lengths of the first adjusting member and the second adjusting member and setting the multi-sided fixing belt 58, the goods group is further fixed in the packaging device. As Figure 5 and Figure 6 shown, it is the case where the covering cloths are connected to form a three-dimensional structure and an accommodating space is formed inside.

[0074] In practical applications, the external tray is a rectangular tray, and one or more tray bottom columns are provided at the edge of the external tray. When the goods group is placed on the external tray for logistics transportation, the fixing member 57 includes a fixing ring buckle. The multi-sided fixing belt 58 extends from the second covering cloth 22 and / or the fourth covering cloth 24, passes through the tray bottom column at the bottom of the external tray from this side, and extends out from one side of the first covering cloth 11 and / or the third covering cloth 23, and passes through the fixing ring buckle of the fixing member 57 on the first covering cloth 11 and / or the third covering cloth 23 to be fixed on the side where the first covering cloth 11 and / or the third covering cloth 23 are located. The multi-sided fixing belt 58 is bound through three orientations of the packaging device, so that the corners of the three-dimensional structure formed after wrapping the goods group can have stronger stability.

[0075] It should be noted that as long as it can be realized that the entire packaging device is bound to the bottom of the external tray through the multi-sided fixing belt 58, the multi-sided fixing belt 58 and the fixing member 57 can be provided on any covering cloth except the top covering cloth 11. In practical applications, the multi-sided fixing belt 58 can be bound to one or more tray bottom columns in the external tray to enhance the stability of the binding of the multi-sided fixing belt 58 to the packaging device.

[0076] In practical applications, when the height of the goods group is lower than the height of the accommodation space formed between the covering cloths, it can be adjusted by one end being located on the third covering cloth 23, the other end being located on the first covering cloth 21, and passing through the vertical fastening belt on the top covering cloth 11. When the height of the goods group is relatively low, the vertical fastening belt can be tightened, so that the distance between the first covering cloth 21 and the third covering cloth 23 is reduced, and the top covering cloth 11 is retracted, so that the height of the accommodation space formed by the covering cloths can adapt to the goods group; when the width of the goods group is smaller than the width of the accommodation space formed between the covering cloths, it can be adjusted by the horizontal fastening belt located on the third covering cloth 23. When the goods group is relatively narrow, the horizontal fastening belt can be tightened, so that the distance between the second covering cloth 22 and the fourth covering cloth 24 is reduced, and the third covering cloth 23 is retracted, so that the width of the accommodation space formed by the covering cloths can adapt to the goods group.

[0077] In practical applications, through the process of folding and rolling up the covering cloths in various orders, the top covering cloth 11 can be used as the folding center and the rolling center. During the folding process, the second covering cloth 22, the third covering cloth 23 and the fourth covering cloth 24 are folded inward, and the multi-sided fixing belts 58, vertical fastening belts and horizontal fastening belts provided on the second covering cloth 22, the third covering cloth 23 and the fourth covering cloth 24 can be wrapped inside without being exposed, making the rolled-up covering cloth cleaner and easier to store. When covering the goods group, only the folded covering cloth needs to be placed on the top of the goods group, and the rest of the covering cloths can be unfolded with the top of the goods group, that is, the top covering cloth 11 as the base point. It can be realized that during the whole process of unfolding, the covering cloth can complete the packaging of the goods group without touching the ground, so that the environment where the packaging device is located can be kept hygienic and clean without being polluted by the ground.

[0078] This embodiment provides a packaging device. By setting a top covering cloth, a first covering cloth, a second covering cloth, a third covering cloth, and a fourth covering cloth, and making the covering cloths connected or detachably connected, it is unfolded from a plane to form a three-dimensional accommodating space that can be used to accommodate goods. Further, by setting a first distance adjustment member and a second distance adjustment member on each covering cloth to adjust the distance between different covering cloths, so that the user can make the accommodating space formed by the covering cloths more adaptable to the volume of the goods according to the actual situation. It can effectively collect and fix the goods, cover the goods in multiple directions, waterproof and dustproof, and can effectively realize the collective transportation of goods in various situations, improve the logistics transportation efficiency, and can be reused at the same time. On the premise of ensuring the safety of the goods, it takes into account functions such as waterproofing and dustproofing, greatly reduces the use of disposable plastic winding films, reduces costs, reduces plastic use and carbon emissions. Further, by setting connecting members, etc. to achieve the storage and folding between the covering cloths, the storage problem of the packaging device when not in use can be effectively solved. During the process of storing and unfolding the packaging device, it can not touch the ground and is not polluted by the ground.
