[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model proposes a lightweight, highly airtight storage and transportation box. The storage and transportation box includes a lower box body and a matching upper box body. The lower box body includes a first metal frame disposed inside a first buffer layer. The outer surface of the first buffer layer is provided with a first skin. The upper box body includes a second metal frame disposed inside a second buffer layer. The outer surface of the second buffer layer is provided with a second skin. The first metal frame includes two first longitudinal support ribs, and a plurality of first transverse support ribs are spaced apart between the two first longitudinal support ribs. The second metal frame includes two second longitudinal support ribs, and a plurality of second transverse support ribs are spaced apart between the two second longitudinal support ribs. Adjacent first transverse support ribs and adjacent second transverse support ribs are connected by short ribs.

[0006] Furthermore, there are four first transverse support ribs and four second transverse support ribs. The first metal frame is provided with two fork slots and lifting rings. The two fork slots are respectively welded to the two first transverse support ribs in the middle of the first metal frame. The second metal frame is provided with lifting rings.

[0007] Furthermore, the upper and lower boxes are sealed together by a sealing assembly, which provides the storage and transportation box with functions such as rain protection and airtightness. The sealing assembly includes a quick-opening latch and a sealing strip. The sealing strip is located on the upper surface of the lower box, and the upper and lower boxes are closed by the quick-opening latch.

[0008] Furthermore, a groove is provided along the circumferential direction on the upper surface of the lower housing, the sealing strip is a T-shaped sealing strip with the vertical strip embedded in the groove, the horizontal strip is in contact with the upper surface of the lower housing, and a through hole is provided in the center extension direction of the horizontal strip.

[0009] Furthermore, the storage and transportation box is also equipped with a conductive plate assembly, which includes a first conductive plate and a second conductive plate. The first conductive plate is disposed on a first metal frame, and the second conductive plate is disposed on a second metal frame. The first conductive plate and the second conductive plate are connected by a conductive spring to realize the conduction between the upper box and the lower box.

[0010] Furthermore, both the first and second buffer layers are PVC foam layers, and both the first and second skins are fiberglass skins.

[0011] Furthermore, corner protectors are provided at the four corners of the lower end of the lower housing.

[0012] Furthermore, the inner wall of the lower housing is provided with an ammunition adapter, and the upper end of the ammunition adapter is provided with a matching clamp assembly.

[0013] Furthermore, the storage and transportation box is also equipped with an inflation valve, an venting valve, a safety valve, and a grounding post, and a positioning sleeve is provided at the bottom of the lower box.

[0014] Furthermore, the storage and transportation box is equipped with stacking pins, which are disposed on the second metal frame; both the first metal frame and the second metal frame are welded from hollow square steel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The storage and transportation box of this utility model adopts a structure with a pre-embedded metal frame in the buffer layer, which improves the strength of the storage and transportation box while giving it lightweight characteristics, thus reducing the difficulty of transporting the storage and transportation box; the metal frame ensures that the storage and transportation box meets the strength requirements of complex mechanical environments and various working conditions; the buffer layer is lightweight and can significantly improve the impact resistance of the storage and transportation box during movement, ensuring the safety of the ammunition inside; the skin on the outer surface of the buffer layer serves as a protective layer, ensuring that the storage and transportation box can withstand the test of harsh natural environments such as marine environments with high salt and high humidity, thus improving the environmental adaptability of the storage and transportation box.

[0016] (2) The sealing component of the storage and transportation box of this utility model has a simple structure and excellent sealing performance.

The quick-opening buckle can dynamically adjust the pre-tightening force between the upper and lower boxes, ensuring the dynamic stability of the storage and transportation box and extending the box life. It is suitable for extreme environments under different conditions. The sealing strip is a T-shaped sealing strip and the center of the horizontal strip of the sealing strip is provided with a through hole, which can further ensure the sealing performance after the upper and lower boxes are closed. When the quick-opening buckle is tightened, the air inside the sealing strip can flow through the through hole, reducing deformation resistance and making the sealing strip fit the joint surface of the upper and lower boxes better. When the quick-opening buckle is loosened, the through hole can help the sealing strip quickly return to its original shape, avoiding "plastic deformation" caused by long-term compression, extending the service life of the sealing strip and ensuring its long-term effective sealing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] Example 1 refer to Figures 1 to 3 This embodiment proposes a lightweight, highly airtight storage and transportation box. The storage and transportation box includes a lower box body and a matching upper box body. The lower box body includes a first metal frame 1, which is embedded inside a first buffer layer 2. A first skin 3 is provided on the outer surface of the first buffer layer 2. The upper box body includes a second metal frame 4, which is embedded inside a second buffer layer 5. A second skin 6 is provided on the outer surface of the second buffer layer 5. The first metal frame 1 includes two first longitudinal support ribs 101, and a plurality of first transverse support ribs 102 are spaced apart between the two first longitudinal support ribs 101. The second metal frame 4 includes two second longitudinal support ribs 401, and a plurality of second transverse support ribs 402 are spaced apart between the two second longitudinal support ribs 401. Adjacent first transverse support ribs 102 and adjacent second transverse support ribs 402 are connected by short ribs 7. The first buffer layer 2 and the second buffer layer 5 are both PVC foam layers, and the first skin 3 and the second skin 6 are both fiberglass skins.

[0022] In this embodiment, the container is composed of a metal frame, a buffer layer, and a skin. The metal frame is embedded within the buffer layer, which can be made of lightweight PVC foam. This ensures the overall lightweight design of the container while significantly improving its impact resistance during movement, thus guaranteeing the safety of the ammunition inside. The metal frame design ensures the container's strength under complex mechanical environments such as vibration, tilting, swaying, and drop impacts. The skin on the outer surface of the buffer layer acts as a protective layer, ensuring the container can withstand harsh natural environments such as high salt, high humidity, and high temperature, improving its environmental adaptability. In this embodiment, the skin is made of fiberglass. Fiberglass has a low density, effectively reducing the overall weight of the container, and possesses excellent corrosion resistance, water resistance, mechanical strength, flame retardancy, and antistatic properties, ensuring the container meets the requirements of special scenarios. Therefore, the container proposed in this embodiment is lightweight while possessing excellent strength and impact resistance, and is suitable for various extreme environments.

[0023] refer to Figure 2 and Figure 3In the above embodiments, in order to meet the strength requirements of the storage and transportation box during the transfer process, the number and position distribution of the first transverse support rib 102 and the second transverse support rib 402 can be determined according to the design requirements. In this embodiment, the first transverse support rib 102 and the second transverse support rib 402 are both set to 4 groups. The first metal frame 1 is provided with two fork slots 8 and lifting rings 9, wherein the two fork slots 8 are respectively welded to the two first transverse support ribs 102 in the middle of the first metal frame 1. The second metal frame 4 is also provided with lifting rings 9. The lifting rings 9 on the first metal frame 1 are used to lift the upper body of the storage and transportation box, and the lifting rings 9 on the second metal frame 4 are used to lift the entire storage and transportation box. The number and position of the lifting rings 9 on the first metal frame 1 and the second metal frame 4 can be determined according to design requirements. Stability during the lifting process must be ensured. Those skilled in the art should understand that, in order to achieve the purpose of lifting the entire storage and transportation box, it is not limited to setting lifting rings 9 on the second metal frame 4. The lifting rings 9 on the first metal frame 1 can also be universal, that is, they can be used to lift both the upper body and the entire storage and transportation box. The fork slots 8 can be connected to the second metal frame 4 by welding for use when transporting with a forklift.

[0024] refer to Figure 2 and Figure 4 To ensure the airtightness of the storage and transportation box, the upper and lower boxes are sealed together by a sealing assembly 10. The sealing assembly 10 includes a quick-opening latch 1001 and a sealing strip 1002. The sealing strip 1002 is located on the upper surface of the lower box. The upper and lower boxes are detachably connected by the quick-opening latch 1001, which is preferably a threaded latch, such as the HFQ41-30 threaded latch manufactured by Qiaheda or other suitable latches on the market. The sealing strip 1002 is a T-shaped sealing strip. A groove 11 is provided circumferentially on the upper surface of the lower box. The vertical strip of the sealing strip 1002 is embedded in the groove 11, and the horizontal strip is fitted against the upper surface of the lower box. A through hole is provided in the center extension direction of the strip; the sealing component in this utility model has a simple structure and excellent sealing effect. The sealing strip 1002 and the quick-opening latch 1001 work together to ensure the sealing of the upper and lower boxes, ensure the dynamic stability of the storage and transportation box and extend the box life, and are suitable for extreme environments under different conditions; when the quick-opening latch 1001 is tightened, the air inside the sealing strip 1002 can flow through the through hole, reducing deformation resistance and making the sealing strip 1002 fit the joint surface of the upper and lower boxes better; when the quick-opening latch 1001 is loosened, the through hole can help the sealing strip 1002 quickly return to its original shape, avoid "plastic deformation" caused by long-term compression, extend the service life of the sealing strip 1002, and ensure its long-term effective sealing.

[0025] In the above embodiments, a conductive plate assembly is also provided inside the storage and transportation box. The conductive plate assembly includes a first conductive plate and a second conductive plate. The first conductive plate is welded to the first metal frame 1, and the second conductive plate is welded to the second metal frame 4. The first conductive plate and the second conductive plate are connected by a conductive spring. The conductive spring is detachably connected to the first conductive plate and the second conductive plate. The first conductive plate is conductive to the metal parts on the lower box body, and the second conductive plate is conductive to the metal parts on the upper box body. In this embodiment, the conductive assembly can ensure that the metal parts between the upper and lower boxes are conductive to each other.

[0026] refer to Figure 2 To ensure the stability of ammunition within the storage and transport container, a locking mechanism matching the shape of the ammunition can be installed inside the container. This mechanism includes an ammunition adapter 13 and a clamp assembly 14. The ammunition adapter 13 is located on the inner wall of the lower container and is reliably connected to a metal embedded part welded to the first metal frame 1 via a base. The base and the embedded part can be connected by bolts. The clamp assembly 14 is located at the upper end of the ammunition adapter 13 and is connected to the base of the ammunition adapter 13 via a quick-opening latch. The ammunition adapter 13 and the clamp assembly 14 work together to secure the ammunition, stabilizing its position, buffering external impacts, preventing damage from shaking and collisions within the container, and ensuring safe transport and storage.

[0027] Furthermore, corner protectors 12 are provided at the four corners of the lower end of the lower box to protect the four corners of the bottom of the storage and transportation box.

[0028] The storage and transportation container is also equipped with an inflation valve, an venting valve, a safety valve, a grounding post, a thermometer / hygrometer, and a pressure gauge. The inflation valve allows for the filling of the container with inert gas or other required gases. The safety valve's function is to release pressure when pressure changes occur due to chemical reactions within the container, preventing excessive pressure from causing an explosion or other hazards. It also balances the internal and external pressures, preventing the intrusion of harmful gases and moisture, thus protecting the stability and safety of the ammunition. The venting valve allows for the rapid expulsion of air from the container. The grounding post ensures rapid grounding of the container, promptly conducting static electricity generated during transportation and storage to the ground, preventing static electricity buildup that could lead to sparks and potentially cause explosions or combustion of the ammunition, thus ensuring the safety of the ammunition and related facilities. The thermometer / hygrometer monitors the real-time temperature and humidity inside the container, and the pressure gauge monitors the real-time pressure inside. The distribution and connection method of the inflation valve, deflation valve, safety valve, grounding post, temperature and humidity meter, and pressure gauge to the storage and transportation box can be determined as needed. Preferably, the inflation valve, deflation valve, safety valve, grounding post, temperature and humidity meter, and pressure gauge are connected to the second metal frame 4, and the grounding post is connected to the first metal frame 1. The bottom of the lower box is provided with a positioning sleeve 15 for quick connection with the transfer and supply equipment.

[0029] In order to guide the closing of the upper and lower housings, several mutually cooperating positioning pins can be set on the upper and lower housings, respectively installed at symmetrical positions on the long side of the upper and lower housings. In this embodiment, four positioning pins are set.

[0030] The storage and transportation box can also be equipped with a file box and a card slot. The file box can hold technical documents such as resumes, and the card slot can hold labels.

[0031] A handle can also be provided on the upper box for manually opening the upper box. In this embodiment, there are 4 handles, 4 of which are distributed on each side of the upper box.

[0032] To further ensure the sealing and waterproof performance of the storage and transportation box, a rain guard 17 can be provided on the inner side of the upper surface of the lower box. The rain guard 17 works in conjunction with the sealing component 10 to further ensure the sealing and waterproof performance of the storage and transportation box, and to further reduce the design difficulty of the sealing component 10.

[0033] To ensure safety during the stacking process of the storage and transportation boxes, stacking pins 16 can also be provided on the second metal frame 4 of the storage and transportation box. The number and distribution of the stacking pins 16 can be determined according to the design requirements. In this embodiment, there are two stacking pins 16, which are diagonally distributed on the upper surface of the storage and transportation box to ensure that the upper and lower boxes will not move along the contact surface when the storage and transportation boxes are stacked.

[0034] Both the first metal frame 1 and the second metal frame 4 are welded from hollow square steel. The square cross-section of the square steel ensures that the stress is relatively uniform in all directions, and it has good resistance to torsion and bending, which can ensure that the storage and transportation box maintains a stable shape and prevents it from twisting or collapsing under various conditions. At the same time, the hollow structure of the square steel can effectively reduce the overall weight of the storage and transportation box. The preferred material of the square steel is 304 or 316L.

[0035] In the above embodiments, all components do not protrude from the surface of the storage and transportation box, making them easy to stack and arrange. This effectively utilizes transportation space and storage area, improves transportation efficiency and storage density, and also reduces the possibility of damage to the packaging box or snagging between components during transportation.

[0036] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0037] It should be understood that this utility model is not limited to the content already described above, and modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
