Description

Technical Field

[0001] The present invention relates to the technical field of airdrop boxes, and in particular to a rotationally molded airdrop box. Background Art

[0002] An airdrop box is a container specifically designed for high-altitude delivery. Its primary function is to ensure the safe and intact delivery of its contents to its destination in complex and volatile delivery environments. It is widely used in military operations, emergency rescue, outdoor adventures, and commercial logistics. It is a high-strength, weather-resistant transport vehicle commonly used in airdrop operations, long-distance resupply, and disaster relief scenarios. The airdrop box's collision resistance is a core element of its design, requiring it to withstand the immense impact of a fall to prevent damage to its contents. Therefore, its collision resistance directly impacts the success rate and safety of material delivery.

[0003] Currently, airdrop boxes are generally equipped with anti-collision structures such as cone frames, reinforcing protrusions, and airbag layers to disperse gravity. Patent document CN117963313A discloses a parachute-free airdrop box for drones. The box comprises a hollow elastic component, a protective cover mounted on the box via a first locking component, a limiting protrusion provided between the box and the cover, an inner box body mounted within the box and mating with the box, a hollow elastic component provided between the inner box and the cover, an inner box cover mounted on the box and mating with the box, an inner box sealing ring provided between the inner box and the cover, a removable connection between the inner box and the cover via a second locking component, and a hollow elastic component provided between the protective cover and the cover. The box and cover serve as an outer protective layer, while the inner box and cover serve as an inner protective layer. A hollow elastic component is provided between the outer and inner protective layers to provide shock absorption and protect the items.

[0004] However, this solution still has the following problems: although the items are placed between the inner and outer protective layers, collisions may occur between the items, and the items may still be damaged. Other existing technologies place items by customizing the partition space according to the size of the items, but after the partition space is customized, only designated items can be placed, which is very limited. Some existing technologies also separate items by placing foam partitions in the box, but the sizes of the items are different, and the space separated by the foam partitions is not convenient for placing items of different sizes, resulting in gaps between some items and the foam partitions, which increases the shaking of the items. At the same time, the space inside the box cannot be fully utilized, and the items are prone to damage. Summary of the Invention

[0005] The present invention provides a rotationally molded airdrop box, which aims to solve the problem in the related art that items may shake or items in the box may be damaged due to collision.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 11 As shown, the roto-molded airdrop box of the present invention includes a box body 1, a placement cavity 2 is provided in the box body 1, and the placement cavity 2 is used to place items 01. The airdrop box in this embodiment is a roto-molded airdrop box, and a mounting groove 3 is provided in the box body 1, and the mounting groove 3 is connected to the placement cavity 2. A partition component 4 and a reeling component 5 are provided in the box body 1, the partition component 4 is provided in the placement cavity 2, and the reeling component 5 is provided in the mounting groove 3. The partition component 4 is connected to the reeling component 5 through the connection between the placement cavity 2 and the mounting groove 3. When placing items 01, the items 01 are placed in the placement cavity 2 in sequence, and then the reeling component 5 cooperates with the partition component 4 to separate the items 01, and at the same time protects the items 01 to reduce the phenomenon of items 01 colliding with each other in the box body 1.

[0038] Reference Figure 3 A communication port 11 is opened in the box body 1 , and the placement cavity 2 and the installation groove 3 are communicated through the communication port 11 .

[0039] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The partition assembly 4 includes a partition strip 41 and an insertion rod 42. One end of the partition strip 41 is connected to the inner wall of the placement chamber 2, and the other end extends through the communication port 11 into the mounting slot 3 to connect to the reel assembly 5. The reel assembly 5 is used to reel the partition strip 41. The line connecting the communication port 11 and the end of the partition strip 41 facing away from the reel assembly 5 is parallel to the inner wall of the placement chamber 2. In other words, when no item 01 is placed, the portion of the partition strip 41 located within the placement chamber 2 is parallel to one of the side walls of the placement chamber 2. The insertion rod 42 is located on the side of the partition strip 41 closest to the inner wall of the placement chamber 2. Multiple insertion rods 42 are provided.

[0040] Reference Figure 10A slot 21 is provided on the bottom wall of the placement cavity 2 , and a plurality of slots 21 are provided, and the plurality of slots 21 are evenly distributed throughout the placement cavity 2 .

[0041] The winding assembly 5 winds up the separating tape 41 and tensions the separating tape 41 so that when no object 01 is placed, the separating tape 41 can be close to the inner wall of the placement cavity 2 so that the object 01 can be placed in the placement cavity 2.

[0042] For ease of understanding, it is defined here that the sides of the object 01 that are not in contact with the inner wall of the placement chamber 2 and the dividing strip 41 are all exposed sides.

[0043] Reference Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 After placing the item 01 in the placement chamber 2, first place the item 01 close to the inner wall of the placement chamber 2 and the dividing strip 41, then manually hold the insertion rod 42 and move the insertion rod 42. As the insertion rod 42 moves, the corresponding part of the dividing strip 41 is pulled to move accordingly. The winding component 5 maintains the pulling force on the dividing strip 41 while releasing the dividing strip 41, and moves the insertion rod 42 to pass through the exposed side of the item 01 in turn. At the same time, the dividing strip 41 is unfolded and abuts against the exposed side of the item 01. Then, the insertion rod 42 is buckled into the corresponding slot 21 and fixed there, so that the dividing strip 41 and the item 01 remain in abutment.

[0044] Reference Figure 6 、 Figure 7 When continuing to place items 01, arrange them in sequence, and prioritize placing item 01 close to the inner wall of the placement chamber 2, and then place item 01 close to the dividing strip 41, ensuring that at least one side of each item 01 placed is in contact with the inner wall of the placement chamber 2 or the dividing strip 41. Then repeat the above operation, move the remaining insertion rods 42, and drive the dividing strip 41 to expand and abut the exposed side of the subsequently placed items 01. Move the corresponding insertion rod 42 each time an item 01 is placed. After the items 01 are completely placed, there is a dividing strip 41 between every two items 01. The dividing strip 41 blocks the items 01, reduces direct contact between the items 01, and thereby reduces damage to the items 01 due to collision, thereby protecting the items 01.

[0045] Reference Figure 2 The winding assembly 5 and the dividing assembly 4 are provided in two groups. The dividing strips 41 in the two groups of winding assemblies 5 are respectively provided on the two opposite side walls of the placement chamber 2. That is, when no object 01 is placed, the dividing strips 41 in the two groups of dividing assemblies 4 are parallel to each other in the placement chamber 2. In this way, the dividing strips 41 can separate any two adjacent objects 01.

[0046] Reference Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 The winding assembly 5 includes a winding rod 51 and a torsion spring (the torsion spring is not shown in the figure). The winding rod 51 is rotatably arranged in the mounting groove 3. The end of the dividing strip 41 facing away from the placement cavity 2 is connected to the side of the winding rod 51. One end of the torsion spring is connected to the inner wall of the mounting groove 3, and the other end is connected to the winding rod 51. The torsion spring is used to drive the winding rod 51 to rotate, thereby winding the dividing strip 41.

[0047] Reference Figure 9 When the dividing strip 41 separates the items 01, the dividing strip 41 unfolds and pulls the reeling rod 51 to rotate. After the insertion rod 42 is separated from the slot 21, the torsion spring can drive the dividing strip 41 to reel to its initial state through the reeling rod 51.

[0048] Reference Figure 4 、 Figure 8 Guide rod 1 6 , guide rod 2 7 , and guide frame 8 are disposed within mounting slot 3 . Guide rod 1 6 is rotatably mounted within mounting slot 3 , and guide frame 8 slides toward the center of take-up rod 51 . Guide rod 2 7 is mounted on the side of guide frame 8 near take-up rod 51 , and they rotate in conjunction with guide frame 8 . A spring 31 is disposed within mounting slot 3 . Spring 31 is configured as a spring and is connected to the inner wall of mounting slot 3 and guide frame 8 , respectively. Spring 31 is used to drive guide frame 8 toward take-up rod 51 .

[0049] The dividing strip 41 passes through the guide rod 1 6 and the guide rod 2 7 in sequence and is then wound on the winding rod 51. When the winding rod 51 winds up the dividing strip 41, the elastic member 31 drives the guide rod to always be in contact with the dividing strip 41 wound on the winding rod 51, and as the thickness of the wound dividing strip 41 gradually increases, the guide frame 8 also moves accordingly to improve the quality of the dividing strip 41 when it is wound up.

[0050] Reference Figure 8 Two extrusion plates 9 are provided on the guide frame 8. The two extrusion plates 9 are respectively arranged on both sides of the dividing strip 41. An extrusion surface 91 is provided on the side of the two extrusion plates 9 close to each other. The extrusion surface 91 is arranged on the side of the extrusion plate 9 away from the winding rod 51, so that the distance between the two extrusion plates 9 gradually decreases in the direction toward the winding rod 51.

[0051] When the winding rod 51 winds up the dividing tape 41 , the extrusion surface 91 squeezes the sponge portion 412 in the dividing tape 41 to reduce the thickness of the dividing tape 41 when it is wound around the winding rod 51 , thereby improving the stability of the dividing tape 41 when it is wound up.

[0052] Reference Figure 9The dividing strip 41 includes a covering portion 411 and a sponge portion 412. The sponge portion 412 is disposed within the covering portion 411. Multiple sponge portions 412 are sequentially arranged along the length of the dividing strip 41. After the dividing strip 41 separates the items 01, the sponge portions 412 within the dividing strip 41 buffer and absorb external vibrations, reducing the shaking of the items 01 and thus protecting the items 01.

[0053] Reference Figure 10 、 Figure 11 A clearance groove 421 is provided at the lower end of the insertion rod 42, and the clearance groove 421 is provided on the side of the insertion rod 42. A spring piece 422 is provided in the clearance groove 421. The spring piece 422 is arranged in an arc shape, that is, the spring piece 422 has a convex portion, and the convex portion of the spring piece 422 is located outside the clearance groove 421. After the insertion rod 42 is inserted into the slot 21, the spring piece 422 undergoes elastic deformation and abuts against the inner wall of the clearance groove 421 to improve the stability of the insertion rod 42 and the slot 21.

[0054] Reference Figure 11 A slide rod 423 is provided at the upper end of the insertion rod 42 for sliding up and down, and a clamping sleeve 424 is provided on the slide rod 423. The end of the clamping sleeve 424 facing away from the slide rod 423 is bent downward. There is a gap between the bent portion of the clamping sleeve 424 and the insertion rod 42, and the gap is smaller than the thickness of the dividing strip 41. A guide slope 425 is provided at the lower end of the clamping sleeve 424, and the guide slope 425 is provided on the bent portion of the clamping sleeve 424.

[0055] After the insertion rod 42 is engaged with the slot 21, the slide bar 423 is moved downward, and the slide bar 423 drives the card sleeve 424 to move downward. The bent portion of the card sleeve 424 moves to the side of the dividing strip 41 through the guide slope 425, and at the same time clamps the dividing strip 41, and then fixes the dividing strip 41, so that the dividing strip 41 and the object 01 remain in contact, thereby improving the stability of the fit between the dividing strip 41 and the object 01.

[0056] The implementation principle of the present invention is as follows: a dividing strip 41 and an insertion rod 42 are set in the placement chamber 2, and the dividing strip 41 is connected to the winding rod 51. When placing the item 01, the corresponding insertion rod 42 is moved so that the dividing strip 41 abuts against the exposed side of the item 01. After the item 01 is placed, a dividing strip 41 is evenly spaced between every two adjacent items 01 to avoid direct contact between the two items 01. At the same time, a sponge part 412 is provided in the dividing strip 41 to absorb and buffer external vibrations, thereby protecting the item 01 and reducing damage to the item 01.

[0057] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
