[0029] like Figure 1 As shown, a projectile packaging tube is cylindrical in shape, comprising a cap 1 and a body 2. The cap 1 fits snugly against the body 2, which holds the projectile. The cap 1 and body 2 are an embedded, end-opening structure. When the cap 1 is closed, it is pressed into the body 2, creating a sealed packaging space for the projectile. A locking assembly securely connects the cap 1 and body 2, preventing accidental opening during transport and storage and ensuring the safety of the projectile. The locking assembly consists of a spring steel strip, a pull tab (Q235 steel), a buckle plate (Q235 steel), and a connecting ring (Q235 steel). Heat treatment enhances the surface hardness of the steel strip and increases the locking strength, ensuring it does not deform under tension. A silicone O-ring seal 11 is provided between the inner wall of the cap 1 and the side wall of the cylinder 2. The design incorporates a reasonable compression amount to ensure convenient assembly and operation of the cap 1. The seal 11 has excellent sealing capabilities, filling the gap between the cap 1 and the cylinder 2 to prevent external moisture and dust from entering the packaging cylinder, ensuring a clean and dry storage environment for the pellets and improving the sealing performance of the packaging cylinder. After the cap 1 and cylinder 2 are closed, the cap 1 is secured to the cylinder 2 by a locking buckle, forming a closed structure and ensuring the overall sealing function of the packaging cylinder.

[0030] In the specific implementation of this application, the structures of the cylinder cover 1 and the cylinder body 2 are as follows:

[0031] The cap 1 is made of DC1 steel, which has high rigidity and strength, ensuring that the overall rigidity and strength of the packaging tube meet the requirements for pressurization and sealing. The cap 1 is formed by stamping and stretching, and then electroplated, with the outer surface painted. An integrated handle structure is welded to the outside, with a locking mounting groove on the outside of the handle. The locking mechanism is separate from the cap 1. The internal sealing surface of the cap 1 is machined and polished to ensure that the machining accuracy and roughness of the sealing surface meet the requirements, improving the sealing reliability of the packaging tube.

[0032] The cylinder body 2 is injection molded from high-strength engineering plastic material, with a cylindrical structure in appearance. The inner side mimics the cylindrical structure of ammunition, fitting well with the circular shape of the ammunition, resulting in uniform stress distribution and stable packaging. The outer side of the cylinder body 2 is equipped with a mesh reinforcement structure, ensuring stable positioning and uniform stress distribution after ammunition packaging. The overall rigidity and strength meet the requirements of 0.5 MPa pressurization without deformation. The packaging cylinder of this application is lighter than that made entirely of aluminum alloy or steel, exhibiting excellent lightweight design; while aluminum alloy or steel packaging cylinders also suffer from drawbacks such as high density, heavy weight, the need for local welding processes, and higher overall packaging costs.

[0033] To stably fix the projectile within the packaging tube, this application includes an adapter 3 at the bottom of the inner wall of the tube 2, and a shock-absorbing pad 4 and a buffer ring 5 inside the tube cover 1. One end of the adapter 3 is flush against the bottom of the inner wall of the tube 2, and the outer diameter of the adapter 3 is similar to the inner diameter of the tube 2, ensuring no axial movement of the adapter 3. The adapter 3 is a hollow cylindrical structure, and its hollow portion is adapted to the shape of the projectile head. The projectile head is inserted into the hollow portion of the adapter 3, achieving axial positioning and fixing of the projectile, preventing axial movement within the tube 2, and ensuring the stability of the projectile during transportation and storage. When the projectile tip collides with the packaging tube, the projectile remains firmly positioned and does not shift. The shock-absorbing pad 4 is located between the bottom of the inner wall of the tube 1 and the end face of the projectile tail, effectively absorbing the impact force transmitted to the projectile tail, providing cushioning and shock absorption, and protecting the projectile tail from damage. The shock-absorbing pad 4, in conjunction with the adapter 3, compresses the projectile, ensuring its stable axial fixation.

[0034] The buffer ring 5 is made of rubber and is formed by vulcanization. Rubber has good elasticity and flexibility, which allows it to tightly wrap around the tail of the projectile, effectively absorbing radial impact force while limiting its movement and protecting the projectile. The buffer ring 5 is glued to the inner wall of the cap 1. The tail of the projectile passes through the buffer ring 5. After the projectile is assembled, the inner side of the buffer ring 5 contacts the outer surface of the projectile tail, preventing the projectile from moving radially. Through the cooperation of the buffer ring 5 and the adapter 3, other areas of the projectile are kept in a suspended state, avoiding direct contact between the projectile and the packaging tube to prevent collision damage.

[0035] Through the above structural design and implementation method, the projectile packaging tube of this application has a reasonable structure, can effectively fix the projectile, provide all-round cushioning and shock absorption protection for the projectile, has good sealing performance, meets the needs of projectile transportation and storage, ensures the safety and integrity of the projectile during storage and transportation, and has high practical value.

[0036] In its specific implementation, the adapter 3 includes an adapter body 31 and a limiting ring 32. The adapter body 3 is injection molded from plastic material, and the adapter body 31 has a hollow structure, providing a certain space for the projectile head. The limiting ring 32 is embedded in the adapter body 31, and the inner wall of the limiting ring 32 is adapted to the shape of the projectile head, perfectly fitting the arc of the projectile head to achieve more precise and secure fixation of the projectile head. Simultaneously, the adapter 3 also includes a soft felt 33 bonded to the inner wall of the limiting ring 32. The felt 33 is located in the contact area between the inner wall of the limiting ring 32 and the projectile head, which, while fixing the projectile head, prevents hard wear and damage to the projectile head, ensuring good protective performance for the projectile surface.

[0037] In the specific implementation of this application, the shock-absorbing pad 4 consists of an injection-molded partition 41 and a buffer pad 42. The buffer pad 42 is made of EVA foam board and is disposed on both sides of the injection-molded partition 41. The partition 41 serves as a support and divider, and the buffer pads 42 on both sides can buffer and dampen the tail of the projectile from different directions, enhancing the shock absorption effect. This structural design ensures that the shock-absorbing pad 4 has high support strength and good cushioning and protection performance.

[0038] In the specific implementation of this application, a plug 21 with an external thread structure is provided at the bottom of the cylinder 2. A threaded hole is provided at the bottom of the cylinder 2 for assembling the plug 21, and the plug 21 is threadedly connected to the threaded hole of the cylinder 2. A silicone O-ring sealing ring 22 is also provided between the plug 21 and the cylinder 2. When the plug 21 is screwed to the cylinder 2, the sealing ring 22 is compressed to achieve a sealing function, further enhancing the sealing performance at the bottom of the cylinder 2. Strong adhesive is used to bond the threaded connection to ensure a firm connection of the plug 21, achieving a sealing function, preventing the plug 21 from loosening, and giving the packaging cylinder a high pressure-holding and sealing function, capable of maintaining +40KPa and -40KPa for 1 minute without leakage.

[0039] The plug 21 is equipped with a pressure regulating valve 23, which is an injection-molded circular disc structure with a bolt integrally injection-molded within it. The plug 21 is also an injection-molded circular structure with a nut integrally injection-molded within it. A sealing gasket 24, consisting of 24 silicone gaskets, is placed between the plug 21 and the pressure regulating valve 23 to prevent gas leakage between them. The bolt of the pressure regulating valve 23 is threadedly connected to the nut of the plug 21, compressing the sealing gasket 24 to achieve a seal. The opening degree of the pressure regulating valve 23 can be adjusted by rotating the bolt, thereby regulating the internal pressure of the packaging cylinder to adapt to different storage and transportation environments, maintaining stable air pressure inside the cylinder 2, and preventing pressure fluctuations from affecting the projectiles.
