[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 The present invention provides the following technical solution: an environmentally adaptable ammunition box, comprising a box body 1 and a box cover 3 sealed and assembled on the upper surface of the box body 1.

[0027] Example 1: As Figures 1-7 The technical solution shown is as follows: an environmentally adaptable ammunition box, comprising: a locking buckle 2, installed in a groove on the outer surface of the box body 1, and the locking buckles 2 are evenly arranged about the groove of the box body 1; a locking buckle 4 is installed on the upper side of the outer surface of the box cover 3, and the locking buckle 2 is connected to the box cover 3 through a tightness adjustment mechanism; the box body 1 is connected to the box cover 3 through a sealing support mechanism to control the safety of ammunition body placement; and a detection port 16 is assembled on the left side of the outer surface of the box body 1, and a detection port 22 is assembled on the right side of the outer surface of the box body 1.

[0028] In use, the locking buckle 2 installed on the box body 1 is used to lock the assembled box cover 3, and the locking buckle 4 installed on the box cover 3 is used to effectively engage the stacked boxes 1, improving the stability of the stacked assembly. In conjunction with the sealing support mechanism inside the box body 1, the stability of the ammunition body assembly is controlled. Furthermore, the tightness adjustment mechanism improves the stability of the assembly between the box body 1 and the box cover 3.

[0029] Example 2: Figures 1-4 The technical solution shown, based on Embodiment 1, further discloses an improvement in assembly stability during the assembly of the ammunition body inside the box 1, solving the problem of leakage at the connection between the box cover 3 and the box 1, which affects the dryness and humidity of the internal ammunition body. The specific details are as follows: The tension adjustment mechanism also includes a tensioning seat 7 rotatably connected to the outer surface of the locking buckle 2, and a tensioning rod 8 is threadedly connected to the inner surface of the tensioning seat 7. A fixing buckle 9 is engaged with the outer surface of the tensioning rod 8, and the fixing buckle 9 is installed on the outer surface of the box cover 3; Figure 3 As shown, the locking buckle 2 and the tensioning seat 7 form a rotating structure, and the tensioning seat 7 forms a threaded limiting structure with the tensioning rod 8 through the nut, and the tensioning rod 8 and the fixing buckle 9 form a limiting engagement structure, while the fixing buckle 9 and the box cover 3 form an integrated structure; as shown Figure 4 As shown, the sealing support mechanism also includes a nesting member 5 installed on the upper surface of the housing 1, and a sealing member 6 is attached to the upper surface of the nesting member 5, and the sealing member 6 is nested in the inner surface of the housing cover 3. Meanwhile, a reinforcing frame 10 is installed on the upper side of the inner surface of the housing 1, and a buffer assembly 11 is supported and connected to the upper surface of the reinforcing frame 10. A buffer assembly 12 is nested and connected to the upper surface of the buffer assembly 11, and a locking buckle 13 is rotatably connected to the upper surface of the buffer assembly 12. A desiccant 14 is supported and connected to the end of the upper surface of the reinforcing frame 10, and positioning interior blocks 15 are staggered on the inner surface of the housing 1. Figure 4 As shown, the box body 1 forms a nested sealing structure with the box cover 3 through the nesting part 5 and the sealing part 6, and the box body 1 and the reinforcing frame 10 form an integrated structure. The reinforcing frame 10, the buffer assembly 11 and the buffer assembly 2 12 form a limiting support structure. At the same time, the buffer assembly 11 and the buffer assembly 2 12 form a nested structure with the ammunition body, and the buffer assembly 2 12 forms a locking and engaging structure with the ammunition body through the locking buckle 3 13. The reinforcing frame 10 and the desiccant 14 form a moisture-absorbing structure. At the same time, the box body 1 forms a protective structure with the ammunition body through the positioning interior block 15.

[0030] In use, a reinforcing frame 10 is assembled inside the housing 1. The ammunition body is then assembled via a buffer assembly 11 mounted on the reinforcing frame 10. A second buffer assembly 12 is then assembled on top of the second buffer assembly 11, and another set of ammunition bodies is nested within it. A locking buckle 13, assembled with the second buffer assembly 12, enhances locking stability. After the ammunition body is assembled, positioning interior blocks 15 are attached to its rear end to control its internal safety. The housing cover 3 can then be assembled onto the housing 1, and the tensioning seat 7 and tensioning rod mounted on the locking buckle 12 are connected... The tension rod 8 is adjusted by thread 8 and limited by nut, thereby controlling the tension rod 8 to be assembled on the fixing buckle 9. This controls the stability of the assembly between the box body 1 and the box cover 3, preventing it from falling off. In conjunction with the use of the nesting part 5 and the sealing part 6, the airtightness is increased, which is used in conjunction with subsequent airtightness monitoring. When in use, it is used with desiccant 14, which is mainly used to absorb the moisture that seeps into the box during the long-term storage of missiles. In order to make the humidity of the missile environment inside the box more ideal and uniform, desiccant 14 is placed in four parts: the front, middle and rear of the box bottom and the side of the box to improve the moisture absorption effect.

[0031] Example 3: Figure 5 , Figure 6 and Figure 7 The technical solution shown, based on Embodiment 2, further discloses that the box 1, through external components, provides protection for the ammunition body under different conditions, adapting to various environments, improving environmental adaptability, increasing the safety of the ammunition body inside the ammunition box, and solving the problem of inconvenient monitoring of the internal environment of the ammunition box, which affects the timely assessment of the internal condition of the ammunition box upon opening. The specific details are as follows: A pressure regulating valve 17, a ventilation valve 18, and a humidity indicator 19 are installed on the lower left side of the outer surface of the box 1. A humidity card 20 is attached to the end of the outer surface of the humidity indicator 19, and a housing 21 is threadedly connected to the outer surface of the humidity indicator 19. The humidity card 20 is located between the housing 21 and the humidity indicator 19. Figure 7 As shown, an inflation valve 23, a grounding wire 24, and a QR code covering area 25 are installed on the lower right side of the outer surface of the box 1. The QR code covering area 25 is located in the middle section of the outer surface of the box 1, and a cable bag 26 is installed on the inner surface of the box 1.

[0032] To overcome the difficulty of opening the container due to pressure imbalance caused by changes in ambient temperature and altitude, the container 1 is equipped with a two-way pressure regulating valve 17. This valve 17 is sandproof and waterproof. The relative humidity of the missile's long-term storage environment should not exceed a certain threshold. Under these conditions, the missile body will not get damp or moldy, and the ammunition casing will not easily oxidize. To facilitate monitoring of changes in the missile's storage environment, a humidity indicator 19 is installed on the outside of the container 1. Before opening the container, press the pressure release button. A pressure regulating valve 17 is located above the handle on the side of the container 1. When the opening pressure of the pressure regulating valve 17 is less than a predetermined value, it automatically releases air when the positive pressure difference with the outside exceeds the design value, and automatically draws air when the internal negative pressure difference exceeds the design value, ensuring a balanced and controllable pressure inside the container 1. It also accommodates manual operation. The pressure inside chamber 1 is adjusted for easy opening. Additionally, a waterproof and breathable membrane is added for moisture protection, preventing moisture exchange between the inside and outside. This increases the negative pressure opening pressure, reducing the number of times the packaging box needs to be drawn in, ensuring the air inside the chamber remains dry. Chamber 1 is equipped with a ventilation valve 18 for replacing chamber 1 with dry nitrogen or for rapid pressure relief. It can also be used as an interface to check the airtightness of chamber 1. The pressure regulating valve 17 has a bidirectional pressure regulation function. Whether positive or negative pressure, when the pressure difference reaches the opening pressure of the pressure regulating valve 17, it opens to regulate the pressure, allowing gas to flow from the high-pressure area to the low-pressure area, reducing the pressure difference. When the pressure difference reaches the closing pressure of the pressure regulating valve 17, it closes, achieving a sealed chamber 1. Generally, changes in ambient temperature or altitude will cause the air inside chamber 1 to... When an external pressure difference is formed, if the internal pressure of chamber 1 is greater than the external pressure and exceeds a predetermined value, the pressure regulating valve 17 automatically opens to release air. When the pressure drops below the predetermined value, the pressure regulating valve 17 gradually closes. Similarly, if the internal pressure of chamber 1 is less than the external pressure and exceeds a predetermined value, the pressure regulating valve 17 automatically opens to draw in air. When the pressure drops below the predetermined value, the pressure regulating valve 17 gradually closes. A similar vacuum negative pressure situation applies; the pressure regulating valve 17 can also be opened and closed by pressing the center on / off button. Generally, this is operated before opening chamber 1 and is not required at other times. To facilitate real-time monitoring of environmental parameters such as humidity inside chamber 1, a humidity indicator 19 is designed on chamber 1. This indicator is airtight and equipped with a sealing ring for airtight sealing protection. Using mature box-type accessories, the humidity indicator 19 will change from blue to red when the humidity card 20 reaches the critical point. The process is reversible. The internal humidity card 20 can also be replaced outside the box 1 for easy maintenance. The humidity indicator 19 has a built-in humidity card 20, which makes it easy to observe the humidity environment inside the packaging box 1 and monitor the humidity inside the box 1. If the humidity inside the box 1 exceeds the set value, the humidity indicator 19 will give a clear indication. When the humidity value inside the box 1 exceeds the value marked on the color card, the circular mark of the humidity card 20 corresponding to the marked value will change from blue to pink. Under normal conditions, it will be displayed as blue. Once the humidity card 20 absorbs moisture and turns pink, it can no longer be used. It should be replaced after failure. The humidity card 20 should be checked every six months and replaced once a year. Pay attention when one side of the humidity card 20 turns pink.When the other side area turns pink, replace the desiccant 14. When the last area of ​​the humidity card 20 turns pink, check the humidity indicator window and the inflation valve 23. It can be used in conjunction with the ventilation valve 18 to replace the chamber 1 with dry air or nitrogen. Generally, open the ventilation valve 18, connect the air source to the inflation valve 23 to ventilate the chamber, and lock the ventilation valve 18 to pressurize the chamber 1 to the specified pressure to improve the missile storage environment. It is generally not needed unless the ambient humidity is too high, in which case it is used when resealing the missile after opening the box. Each end face of the chamber 1 is designed with two cable connection flanges, with numbers printed next to the flanges, corresponding to different missile positions. Test cables can be installed, connecting the inside and outside, allowing the missiles inside the chamber 1 to be tested without opening the box. The cable connection flanges are compatible with the external cable interfaces. The flanges and cables have a sealing effect after mating, meeting the needs of the chamber 1 for inflation and sealing testing. The grounding wire 24 is mainly for safety design. In strong electromagnetic environments, the packaging box grounding wire 24 must be grounded. The inflation valve 23 at one end of the chamber 1 has an inflation interface. The inflation interface is a quick-connect type, which is faster to install and has better sealing compared to threaded interfaces. The inflation interface is installed in the groove of the box 1, and does not protrude from the surface of the box 1. Sufficient space is left around it for insertion and removal operations. On the opposite side of the inflation interface, there is a ventilation valve 18. The ventilation valve 18 is normally closed. When the air inside the box needs to be replaced after the box is packed, this valve is opened. At the same time, the inflation valve 23 performs nitrogen filling operation. After the air inside the box is replaced, this valve is closed. The ventilation valve 18 can also act as a vent valve. When it is necessary to open the box, this valve is opened to quickly release the gas inside the box and ensure the safety of opening the box. The upper part of the box 1 is designed with missile cable detection port 16 and detection port 22. The middle area is a QR code covering area 25, which is used to attach QR codes with missile information. In addition, there is a cable bag 26 installed at each of the four corners inside the box 1. The cable bag 26 is designed with an elastic opening and is riveted to the vertical beam inside the box 1 for placing detection cables.
