Description

Technical Field

[0001] The utility model relates to the field of ammunition packaging, in particular to an ammunition metal packaging tube with an end cover structure. Background Art

[0002] Medium-sized ammunition is generally packaged in plastic tubes. Plastic materials have average moisture permeability. When stored in a high-humidity environment for a long time, water molecules can penetrate the plastic box and enter the internal space, affecting the long-term storage of ammunition. In addition, the tube body and tube cover structure of the plastic packaging tube are usually threaded and fastened, which has a large tightening force and causes high fatigue during service operation. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an ammunition metal packaging tube with an end cover structure that has a simple structure, good protection, and can be quickly disassembled and assembled.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A metal packaging tube for ammunition with an end cover structure comprises a tube cover assembly, a tube body assembly and a latch assembly; one end of the tube cover assembly extends into an opening of the tube body assembly, and the latch assembly is mounted on the other end, the latch assembly being connected to a locking pin on a side wall of the tube body assembly; a locking pin is provided between the tube cover assembly and the latch assembly, and the tube body assembly comprises a tube body, a bracket assembly at the end of the body and a support assembly in the middle of the body.

[0006] When in use, the projectile is placed in the cylinder, and its end is placed in the bracket assembly. The bracket assembly positions and fixes the end of the projectile. The support assembly in the middle of the projectile supports and protects the projectile and the inner wall of the cylinder. The cylinder cover assembly is pressed in, and the barrel cover assembly presses the tail of the projectile to ensure the stability of the projectile inside. The connection between the lock assembly and the cylinder is completed, and the locking pin is inserted to complete the packaging. When disassembling and assembling, the locking pin needs to be pulled out and the lock assembly opened to realize the separation of the cylinder cover assembly and the cylinder. The operation is convenient.

[0007] As an optimization, an "O"-shaped sealing ring is provided on the outer wall of one end of the cylinder cover assembly extending into the cylinder body, and a coaxially arranged shock-absorbing pad is bonded on the inner side.

[0008] In this way, it can be ensured that after the lock assembly is fastened, the shock-absorbing pad is compressed to a certain thickness, thereby pressing the elastic body in the axial direction to prevent the elastic body from loosening.

[0009] As an optimization, a quick-connect valve is provided on the cylinder cover assembly.

[0010] In this way, the pressure charging and exhaust joints can be quickly connected to achieve the functions of negative pressure extraction and nitrogen filling.

[0011] As an optimization, the bracket assembly includes a bracket body arranged at the bottom of the cylinder, a limiting ring is provided at the end of the bracket body, and a cylinder guard plate is installed on the inner wall of the limiting ring.

[0012] In this way, the end of the projectile is positioned and fixed to avoid shaking.

[0013] As an optimization, the support member consists of a main body and a rubber pad; the main body is a semicircular arc structure, the rubber pad is adhered to the inner wall of the main body, and the two main bodies are bound to the elastic body by straps.

[0014] In this way, the projectile is ensured to be firmly fixed in the radial direction in the packaging tube, so that the surface of the projectile will not contact the inner wall of the tube, and the projectile is effectively protected.

[0015] As an optimization, the arc-shaped section of the bullet tip of the projectile body is provided with a bullet lifting belt, and the lifting ring of the bullet lifting belt extends beyond the tail of the bullet.

[0016] In this way, the projectile can be easily pulled out of the barrel by lifting the bullet belt.

[0017] As an optimization, an adjustment pad is further provided in the cylinder, and the adjustment pad is movably placed between the tail of the projectile and the shock-absorbing pad.

[0018] In this way, different numbers of adjustment pads are selected for assembly to ensure that the elastic body is firmly fixed in the packaging tube.

[0019] To sum up, the axial cross-sections of the ammunition packaging tube, the tube cover and the tube body are all cylindrical, which is consistent with the circular structure of the projectile, so that the surface of the ammunition positioning part can fit well, with the advantages of uniform force and stable packaging; the tube cover and the tube body are locked by tightening the snap-fit lock, and there are two snap-fit points in total. After removing the lock, the tube cover can be directly pulled out; a lock pin is provided at the opening of the lock, which has an anti-loosening function; soft rubber pads are provided at the contact position between the inner side of the packaging tube and the projectile, and the limiting ring in the arc-shaped section bracket assembly of the projectile head adopts a contoured design, so that the projectile is stably placed radially and axially in the packaging tube and fits tightly. The main material of the packaging tube is aluminum alloy, which has good sealing performance and good permeability to water molecules and air, ensuring that the packaging tube has good sealing performance and adaptability to high humidity environments.
