[0071] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] like Figure 1 and Figure 3 As shown, the aircraft packaging cart provided in this embodiment of the invention includes a frame 1 and multiple support seats 2.

[0073] The frame 1 includes a first frame 11 and a second frame 12 arranged at left and right intervals. The lower side of the first frame 11 has a first slide bar 111, and the lower side of the second frame 12 has a second slide bar 121.

[0074] Multiple support bases 2 are spaced apart along the length of the frame 1. Each support base 2 includes a first support portion 21 and a second support portion 22. The left and right sides of the first support portion 21 are connected to the first frame 11 and the second frame 12, respectively. Notches 211 are provided at the lower ends of both sides of the first support portion 21. A first sliding rod 111 and a second sliding rod 121 are located within the two notches 211, respectively. A first latch 212 is provided at the upper end of the first support portion 21. The second support portion 22 is detachably fixed to the first support portion 21 for convenient layering of items to be transported. A second latch 221 is provided at the upper end of the second support portion 22. A strap 23 is provided at at least one support base 2 at the second latch 221 for easy securing of items to be transported. Foldable casters 24 are provided on the lower side of each support base 2 for convenient use and storage.

[0075] During use, dismantle or partially dismantle (see reference). Figure 3 (As shown), by removing the second support 22, one item to be transported can be placed on the first support 21. Then, the second support 22 is connected to the first support 21, and another item to be transported is placed on the second support 22. Finally, the trolley is pushed into the packaging box 6 (see...). Figure 7 The straps 23 are used to secure the items to be transported, preventing them from shaking or moving during transport. During the pushing process, the casters 24 are folded up one by one. This trolley can better utilize the space inside the packaging box, simultaneously transporting multiple items, improving the space utilization rate of the packaging box, and is simple in structure and easy to operate.

[0076] It should be noted that the main function of caster 24 is to move the flying trailer when pushing it, and to fold it up for storage when placed in the packaging box 6. The specific structure can be achieved using existing technology, and will not be described in detail here.

[0077] It is worth noting that the shapes of the first bayonet 212 and the second bayonet 221 are matched with the shape of the item to be transported, and can accommodate or partially accommodate the item to be transported. For example, if the item to be transported is cylindrical, the first bayonet 212 and the second bayonet 221 are arc-shaped bayonet.

[0078] It is understandable that the main function of the frame 1, composed of the first frame 11 and the second frame 12, is to install the support base 2. The main structure of the first frame 11 and the second frame 12 can be a frame made of plates, a frame made of beams and rods, or a frame made of a combination of plates and rods; no limitation is made here. In one example, see... Figure 2As shown, the first frame 11 also includes a first long rod 112, which is spaced apart from the first sliding rod 111. The first long rod 112 and the first sliding rod 111 are connected by a plurality of first short rods 113. The second frame 12 also includes a second long rod 122, which is spaced apart from the second sliding rod 121. The second long rod 122 and the second sliding rod 121 are connected by a plurality of second short rods 123. This frame structure can minimize the overall mass while meeting the load-bearing requirements.

[0079] In this embodiment, the second support portion 22 and the first support portion 21 can be connected by common methods such as bolts, snap-fit, or quick-release latches, and no specific method is limited here.

[0080] In some embodiments, a desiccant box 3 is provided on the first frame 11 and / or the second frame 12. The desiccant box 3 has multiple through holes for placing desiccant inside to keep the air inside the packaging box dry.

[0081] In some implementations, see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limiting part 4 is provided on the first frame 11 and the second frame 12 respectively. The limiting part 4 includes a limiting frame 41, two first wedge blocks 42 and two second wedge blocks 43. The bottom plate of the limiting frame 41 has an opening 411 for the web plate 612 of the I-shaped track inside the packaging box to pass through. The two first wedge blocks 42 are set on the bottom plate of the limiting frame 41 and are located on both sides of the opening 411 respectively. The slope of the first wedge block 42 is inclined from high to low along the direction of the trolley entering the aircraft packaging box. See Figure 6 As shown, two second wedge blocks 43 are disposed on the lower side of the upper wing plate 611 of the I-shaped track 61, and are located on both sides of the web plate 612. The inclined surfaces of the second wedge blocks 43 slope from low to high along the direction in which the trolley enters the aircraft packaging box. The lower wing plate 613 of the I-shaped track 61 is located outside the limiting frame 41 and connected to the web plate 612. When the trolley enters the set position, the inclined surfaces of the first wedge block 42 and the second wedge block 43 cooperate to restrict the trolley's entry position, thus achieving a limiting effect.

[0082] In some embodiments, for pushing / pulling the trolley, handrails 13 are provided at the ends of the first frame 11 and the second frame 12. The handrails 13 can be crossbars connecting the first frame 11 and the second frame 12, or two curved bars respectively located at the ends of the first frame 11 and the second frame 12. In one example, the handrails 13 are integrally connected to the long bars of the frames (the first long bar and the second long bar).

[0083] In this embodiment, the number of support bases 2 can be set as needed, such as two, three, four, five, etc. Generally, three support bases 2 spaced apart are sufficient to achieve a good fixing effect on the items to be transported. It is worth noting that the straps 23 can be provided only at the first latch 212 and second latch 221 of some support bases 2 to assist in fixing the items to be transported; alternatively, the straps 23 can be provided at all the first latch 212 and second latch 221 of the support bases 2, and this is not limited here. Preferably, the straps 23 are adjustable to accommodate items of different sizes to be transported. Existing technology can be used for the straps 23, and further details will not be provided here.

[0084] In the existing technology, when packaging boxes are transported short distances within the site, they often need to be transferred using specialized packaging box trailers before the goods to be transported are packed into the boxes.

[0085] This embodiment provides an implementation method for transporting packaging boxes using a trolley inside the packaging box. Specifically, based on any of the aforementioned trolleys, at least two additional support platforms 5 are provided. See also... Figure 8 and Figure 9 As shown, the support platform 5 has a support plane and an installation interface 51 identical to that of the second support portion 22. For example, when bolted, the installation interface 51 is a through hole; when snap-fitted, the installation interface 51 is a slot; and when quickly-released, the installation interface 51 is a quick-release latch connector. For usage, please refer to... Figure 8 and Figure 12 As shown, the second support part 22 is removed, and the support platform 5 is installed on the first support part 21. The support plane is located above and can be used to support the packaging box 6, that is, it can carry the packaging box 6 and realize short-distance transfer. When it is transported to the packing site, the support platform 5 is removed again, and the first layer of items to be transported is installed on the first support part 21. Then the second support part 22 is installed on the first support part 21, and the second layer of items to be transported is installed on the second support part 22. The structure is simple and the operation is convenient.

[0086] In this embodiment, the cross-section of the support platform 5 is preferably U-shaped.

[0087] To further improve the limiting effect, in some implementation methods, see [link to implementation details]. Figure 9 As shown, the supporting plane is also provided with a limiting interface 52 for docking with the packaging box legs. See one example. Figure 10 and Figure 11 As shown, the support leg 63 of the packaging box 6 is a rectangular block that protrudes downwards, and the limiting interface 52 is a hole that matches the rectangular block (see...). Figure 9 As shown), it is used to accommodate the rectangular block and to limit the position of the packaging box 6.

[0088] This embodiment also provides an aircraft packaging box, see [link / reference] Figures 5-7 As shown, the device includes any of the aforementioned types of trolleys and an I-shaped track 61 installed inside the packaging box. Multiple rollers 62 are provided on the I-shaped track 61, spaced apart along the length of the track and rotatable relative to it, to rollably support the first slide bar 111 and the second slide bar 121. It should be noted that the use of an I-shaped track 61 inside the packaging box is prior art and will not be described further here.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution, and in the absence of conflict between solutions, the various technical features mentioned in each embodiment can be combined in any way to form other implementation methods that can be understood by those skilled in the art.

[0090] Furthermore, without departing from the scope of the present invention, modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, shall not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
