Description

Technical Field

[0001] This invention relates to the field of military equipment technology, specifically to a military 200kg-class cargo container. Background Technology

[0002] As is well known, in modern military operations, the efficient transportation and proper storage of supplies are crucial to ensuring the successful execution of missions. Military missions often involve a variety of complex scenarios, from terrain-challenged areas such as mountains and jungles to harsh environments such as oceans and deserts, all requiring reliable cargo transport equipment for the transfer and temporary storage of supplies. As a core piece of military equipment undertaking this important task, the performance of cargo containers directly affects the efficiency and success of military operations. The need for a cargo capacity of 200kg or more is common in military operations. For example, resupplying small combat units at the front lines requires transporting various critical supplies, including weapons and ammunition, medical supplies, and communication equipment, with a total weight typically around 200kg. However, existing containerized units designed for this cargo capacity have many problems that urgently need to be addressed. From a protective performance perspective, existing containerized shelters are ill-equipped to withstand the complex and ever-changing battlefield environment and numerous threats. During field transport, they may encounter scratches from branches, impacts from rocks, etc. Ordinary containerized shelter shell materials cannot effectively resist such damage, leading to shelter breakage and threatening the safety of internal supplies. Furthermore, under extreme weather conditions, such as heavy rain and sandstorms, if the shelter lacks adequate waterproofing and dustproofing, internal supplies are prone to moisture and dust ingress, affecting their normal use. In addition, existing containerized shelter protective structures are insufficient to provide reliable protection against potential ignition sources and corrosive substances, failing to meet the stringent requirements for supply safety in military operations. In terms of space utilization, the existing 200kg-class cargo container's internal structural design lacks rationality. On the one hand, fixed cargo storage areas cannot flexibly adapt to goods of different shapes and sizes, resulting in serious space waste and low loading efficiency. For example, when transporting irregularly shaped medical equipment or large communication equipment, the unreasonable layout of the container often prevents full utilization of the space, leaving some space idle, while the actual amount of materials that can be loaded is far lower than the container's theoretical carrying capacity. On the other hand, the lack of an effective cargo classification and storage design within the container leads to various materials being mixed together, which not only increases the difficulty of loading and unloading but also makes them prone to damage due to collisions during transportation. Transportation stability is also a major shortcoming of existing containerized transport units. In military transport, road conditions are often extremely harsh, with bumpy and undulating terrain being commonplace. Existing containerized transport units are severely inadequate in terms of shock absorption and securing measures, lacking effective shock absorption devices and failing to effectively buffer vibrations during transport. This causes frequent shaking and collisions of cargo within the unit, easily leading to damage. Furthermore, the securing methods between the containerized unit and the transport vehicle are unreliable during transport, making it prone to displacement during sudden braking, turns, etc., potentially causing the containerized unit to fall off the transport vehicle and resulting in serious safety accidents. Additionally, when lifting the containerized unit by air, the ropes deform under tension; if the tension is too great or applied too quickly, it may exceed the rope's elastic limit, causing it to break. Furthermore, the diversity of modern military operations demands that cargo containers be highly adaptable to various transport vehicles. However, existing containers perform poorly in this regard. Different types of transport vehicles, such as military trucks, transport aircraft, and helicopters, have different loading interfaces and securing methods, while existing containers often only accommodate one or a few types of transport vehicles, failing to flexibly meet the needs of rapid switching between transport modes in military operations. This limits the flexibility of material transport, and in emergencies, the inability to find suitable transport vehicles in a timely manner may delay the delivery of materials, affecting the execution of military missions. Therefore, existing 200kg-class cargo containers have many shortcomings in terms of protection, space utilization, transport stability, and adaptability to transport vehicles, and can no longer meet the growing needs of modern military operations. Thus, developing a new type of military 200kg-class cargo container with superior performance is of paramount importance and is urgently needed. Summary of the Invention

[0017] To make the technical means, inventive features, objectives and effects of the invention easier to understand, the invention will be further explained below with reference to specific illustrations.

[0018] like Figure 1-2 As shown, the present invention provides a military 200kg-class cargo container, comprising: a base plate 1 and a frame 2 mounted on the base plate 1, wherein the frame 2 includes: crossbars 3 and vertical tubes 4, each crossbar 3 mainly bears the lateral load transfer and support in the frame 2, and each vertical tube 4 mainly bears the vertical load transfer and support in the frame 2, the crossbars 3 and vertical tubes 4 are welded together, and the rigidity of the overall frame 2 is enhanced by the welding connection.

[0019] like Figure 3As shown, the vertical tube 4 has a hollow structure. A through-hole top cover 5 is located at the top of the vertical tube 4, and a through-hole bottom cover 6 is located at the bottom of the vertical tube 4. Either the through-hole top cover 5 or the through-hole bottom cover 6 is detachably connected to the vertical tube 4, so that when either the through-hole top cover 5 or the through-hole bottom cover 6 is detached from the vertical tube 4, the support rod 7 and its elastic component 9 can be installed inside the vertical tube 4. The support rod 7 is fixed inside the vertical tube 4 under the support of the elastic component 9. When both ends of the support rod are subjected to tension or thrust, the support rod 7 moves within the vertical tube 4. The extreme positions of the support rod 7's displacement within the vertical tube are constrained by the first retaining ring 16 and the second retaining ring 17, respectively.

[0020] Furthermore, a support rod retaining ring 8 is provided on the outer side of the support rod 7. The support rod retaining ring 8 is located in the hollow structure. Elastic components 9 are provided between the support rod retaining ring 8 and the through hole top cover 5 and the through hole bottom cover 6, respectively. The two elastic components 9 can abut against the support rod retaining ring 8, so that the support rod 7 can be reset after passive displacement.

[0021] like Figure 3 As shown, the top of the support rod 7, protruding from the through-hole cover 5, is equipped with a rope assembly 11, and the bottom of the support rod 7, protruding from the through-hole cover 6, is equipped with a support foot 10. When airlifting or transporting the container, the entire frame 2 can be lifted simply by inserting a hook into the rope assembly 11. Once the container is transported to the designated location, it can be lowered. After the support foot 10 lands, the support rod 7 moves upward within the vertical tube 4, while the elastic component 9 provides the initial buffer force. If the load inside the frame 2 is too heavy (exceeding 200 kg), the second retaining ring 17 presses tightly against the through-hole cover 6, limiting the upward displacement of the support rod 7 and thus eliminating the downward potential energy of the frame 2. The support rod 7 then resets within the vertical tube 4. In another embodiment, a hydraulic damping buffer (not shown in the figure) is installed between the first retaining ring 16 and the through-hole cover 5. The hydraulic damping buffer absorbs impact energy through a throttling effect, while allowing the hydraulic fluid to slowly return during reset, reducing the rebound speed and preventing severe vibration of the cargo inside the frame 2. Based on... Figure 3 The vertical tube 4 in the middle is to be replaced Figure 2 The internal vertical tube structure is 4.

[0022] The vertical tube 4, with its built-in support rod 7, is located on the side of the frame 2. This vertical tube 4 provides elastic support to the frame 2. When the frame 2 is lifted, the vertical tube 4 with its built-in support rod 7 cushions the lifting speed and protects the rope assembly 11. The initial acceleration of lifting the entire frame 2 by inserting the hook into the rope assembly 11 can reach 3-5 times the acceleration due to gravity. The support rod 7 moves upward a certain distance within the vertical tube 4, providing a certain amount of cushioning to the rope and preventing it from breaking.

[0023] like Figure 4-6In the specific embodiment of the present invention shown, the pull rope assembly 11 includes: a sliding sleeve 12 and a rope body 13. A spiral groove 14 is provided on the outer side of the portion of the support rod 7 protruding from the through-hole top cover 5. A spiral block 15 is provided inside the sliding sleeve 12, matching the spiral groove 14. Both ends of the rope body 13 are connected to the sliding sleeve 12. Here, as the sliding sleeve 12 is lifted by the rope body 13, it rotates along the trajectory of the spiral groove 14. At this time, the rope body 13 will wrap around the pull hook 32, thus stabilizing the frame 2 and preventing it from swaying.

[0024] In a specific embodiment of the present invention, a first retaining ring 16 is provided at the top of the support rod 7, and the first retaining ring 16 is located between the spiral groove 14 and the through hole top cover 5. A second retaining ring 17 is provided at the bottom of the support rod 7, and the second retaining ring 17 is located between the support foot 10 and the through hole bottom cover 6. Here, the first retaining ring 16 is used to limit the downward displacement space of the support rod 7 in the vertical tube 4, which not only prevents the elastic component 9 in the vertical tube 4 from being damaged due to excessive pressure, but also provides a hydraulic damping buffer between the first retaining ring 16 and the through hole top cover 5 to delay the reset time and improve the stability of the support rod 7 in the vertical tube 4. Here, the second retaining ring 17 is used to limit the upward displacement space of the support rod 7 in the vertical tube 4, which not only prevents the elastic component 9 in the vertical tube 4 from being damaged due to excessive pressure, but also supports the frame 2 when the second retaining ring 17 is in close contact with the through hole bottom cover 6.

[0025] Both the first retaining ring 16 facing the top cover 5 of the through hole and the second retaining ring 17 facing the bottom plate 1 of the through hole are provided with buffer pads 18.

[0026] In a specific embodiment of the present invention, the elastic component 9 includes: a pad 19 and a spring 20. The pad 19 and the spring 20 are sleeved on the outside of the support rod 7, and the pad 19 and the spring 20 are located in the upper space between the support rod retaining ring 8 and the through hole top cover 5. The pad 19 and the spring 20 are located in the lower space between the support rod retaining ring 8 and the through hole bottom cover 6; like Figure 6 As shown, there is one or more pads 19 in the upper space; there is one or more springs 20 in the upper space; there is one or more pads 19 in the lower space; and there is one or more springs 20 in the lower space. The function of the pads 19 is to shorten the length of the springs 20. In addition, the pads 19 can also guide the support rod 7, which moves elastically within the vertical tube 4.

[0027] In a specific embodiment of the present invention, the through-hole bottom cover 6 and the vertical tube 4 need to be rigidly connected. Therefore, the through-hole bottom cover 6 is welded to the vertical tube 4, and the through-hole bottom cover 6 will not be damaged after being impacted by the second retaining ring 17.

[0028] In a specific embodiment of the present invention, the support foot 10 includes: a first plate 21, a conical spring 31, and a top head 22. The first plate 21 has a circular hole in the middle. The large diameter end of the conical spring 31 is connected to the first plate 21, and the small diameter end of the conical spring 31 is connected to the top head 22. The bottom end of the support rod 7 passes through the circular hole and passes through the middle of the conical spring 31 to be fixedly connected to the top head 22. Its support foot 10 can provide secondary elastic buffer protection for the frame 2 after the second retaining ring 17 and the through hole bottom cover 6 are rigidly abutted.

[0029] The top part 22 is conical, with a rounded tip and an inwardly curved waist. Its unique structure allows it to be quickly inserted into the soil for positioning in soft soil.

[0030] In a specific embodiment of the present invention, the sum of the distance between the through hole bottom cover 6 and the first plate 21 and the distance between the retraction of the conical spring 31 is less than the distance between the retraction of the spring 20.

[0031] In a specific embodiment of the present invention, a large cover plate 23 is provided inside the top surface of the frame 2. The large cover plate 23 and the base plate 1 are made of lightweight magnesium alloy bulletproof armor. The outside of the frame 2 is covered with a waterproof cloth 24. The large cover plate 23 is connected to one side of the frame 2 by one or more hinges 25, and the large cover plate 23 is connected to the side of the frame 2 away from the hinges 25 by one or more latches 26. The edge of the large cover plate 23 is sealed with silicone foam (compression 30%). When the large cover plate 23 is placed on the frame 2, it has good sealing performance, a waterproof rating of IP68, and can withstand the pressure of 1m water for 72 hours.

[0032] In a specific embodiment of the present invention, three or more support feet 10 are evenly distributed on the lower side of the base plate 1.

[0033] In a specific embodiment of the present invention, two or more gravity sensors 27 are evenly distributed between the frame 2 and the base plate 1. The frame 2 is also equipped with a battery tank 29 and a positioning device 28 for signal transmission and reception. The positioning device 28 transmits signals to a mobile terminal or a fixed terminal 30 through a cloud service. The battery tank 29 provides power to the gravity sensors 27 and the positioning device 28, and can also serve as an emergency reserve point.
