[0002] Weaponry ammunition has high requirements on storage environment, and needs to ensure that long-term storage does not affect its combat performance, especially dangerous items such as missiles and shells. The packaging structure not only needs to provide protection for the stored items during transportation, but also needs to provide high protection during static storage to prevent ammunition from being affected by the environment, such as corrosion.

[0003] At present, some common packaging structures for ordinary ammunition include wooden packaging boxes, but for some high-precision ammunition, sealed packaging structures are usually used. Some use packaging cylinders, which are sealed by a sealing cover to avoid long-term contact of the ammunition with the external environment and corrosion.

[0038] The inside of the cartridge cover 2 is provided with a sealing ring, when the cartridge cover 2 is covered on the cartridge body 1, the sealing ring is pressed tightly on the opening edge of the cartridge body 1,

[0039] In this embodiment, the cartridge cover 2 is connected with the cartridge body 1 through the locking mechanism, compared with the traditional threaded connection mode, the disassembly of the cartridge cover 2 is more convenient and fast, and the sealing performance is easier to ensure.

[0040] Optionally, the handle 3 includes two side plates 31 arranged in parallel, and a top plate 32 connected with the two side plates 31, the side plates 31 and the top plate 32 are all long strip structures, in this embodiment, the two side plates 31 and the top plate 32 are an integral structure, which can be formed by bending a metal plate, or formed by injection molding with a plastic material. At the positions where the first connecting shaft and the second connecting shaft are arranged, the top plate 32 is not covered, so that a hollow part is formed between the two side plates 31 at the positions where the first connecting shaft and the second connecting shaft are arranged, which can provide a avoiding space for the rotation of the locking piece 4.

[0041] At the connecting end of the handle 3, the two side plates 31 form a bending part, the second connecting shaft is connected to the bending part, the two bending parts are bent towards one side, for example, bent at 90 degrees with the side plates 31, so that the main part (side plates 31) of the handle 3 can have a larger activity space, the connecting positions of the first connecting shaft and the two side plates 31 are located on the upper side of the bending part, and the arrangement of the bending part also provides an avoiding space for the movement of the locking piece 4.

[0042] As shown in Figure 4As shown, the outer end surface of the cylinder cover 2 is provided with a protective rib 21, which surrounds a receiving groove. When the locking mechanism is in the locked state, the handle 3 is embedded in the receiving groove. Optionally, two protective ribs 21 are provided in parallel with each other, and the receiving groove is formed between the two protective ribs 21. The height of the protective rib 21 is higher than the side plate 31 of the handle 3, so that the handle 3 can be embedded in the receiving groove, and the handle 3 is protected by the protective rib 21.

[0043] Optionally, the protective rib 21 is provided with a first lock hole 211, and the side plate 31 is provided with a second lock hole 311. When the handle 3 is located in the receiving groove, the first lock hole 211 and the second lock hole 311 are communicated. The locking mechanism further comprises a pin, which is inserted into the first lock hole 211 and the second lock hole 311 to limit the handle 3 in the receiving groove. When the handle 3 is embedded in the receiving groove, the locking piece 4 is in the clamping state with the clamping block 11 on the cylinder body 1. The pin inserted into the first lock hole 211 and the second lock hole 311 can prevent the handle 3 from automatically sliding out, thereby ensuring the reliability of the locking of the locking mechanism.

[0044] The end of the protective rib 21 forms a connecting bracket, that is, the connecting bracket is formed on the protective rib 21. The connecting bracket is provided with a second shaft hole 212, and a second connecting shaft is inserted into the second shaft hole 212. The second shaft can rotate in the second shaft hole 212, so that the handle 3 can complete the overturning action. Optionally, the free end of the handle 3 is formed with a pull tab 33, which is formed by extending from the top plate 32, for example, extending in the horizontal direction or the vertical direction of the top plate 32 at the same time, thereby increasing the area for grasping and facilitating grasping. Correspondingly, the protective rib 21 is formed with an avoiding opening 213, and the position of the avoiding opening 213 corresponds to the position where the pull tab 33 is formed. When the handle 3 is embedded in the receiving groove, a part of the pull tab 33 extends outside the receiving groove through the avoiding opening 213, thereby facilitating the grasping of the pull tab 33 outside the receiving groove.

[0045] In the embodiment, two handles 3 are provided, which are symmetrically arranged on both sides of the cylinder cover 2. The two handles 3 are located on the same straight line in the locked state, and the receiving groove is a straight line type through groove. The two handles 3 can be embedded in the receiving groove at the same time. Optionally, when the two handles 3 are located in the receiving groove, the pull tabs 33 on the two handles 3 overlap, that is, the pull tab 33 of one handle 3 is pressed on the upper side of the other handle 3. At this time, the position of only one handle 3 can be locked by the pin, that is, the position of the handle 3 with the pull tab 33 on the upper side is provided with the first lock hole 211, and the second lock hole 311 which is communicated with the first lock hole 211 is provided on the side plate 31. The position of the handle 3 on the upper side is locked by the pin, and the pull tab 33 on the handle 3 on the upper side presses the pull tab 33 on the handle 3 on the lower side, thereby fixing the position of the two handles 3 in the locked state.

[0046] Optionally, the adjusting valve 5 is arranged on the barrel cover 2, and when the barrel cover 2 is covered on the barrel body 1, the adjusting valve 5 is used for adjusting the air pressure in the barrel body 1. For example, inert gas can be filled into the barrel body 1 to protect the ammunition from corrosion, and the inert gas can be nitrogen or the like, and the adjusting valve 5 can be used to adjust the air pressure in the barrel body 1.

[0047] Further, the reinforcing ribs 22 are arranged on the outer end surface of the barrel cover 2, and the reinforcing ribs 22 are arranged on both sides of the accommodating groove formed by the protective ribs 21. Optionally, a grid structure is formed on the top wall of the barrel cover 2 to improve the structural strength of the barrel cover 2.

[0048] The present application can realize the quick connection and disassembly of the barrel body and the barrel cover, facilitate the ammunition packaging, and quickly take out the ammunition when used, so that the loading of the ammunition can be greatly shortened in time and the loading efficiency is improved. Moreover, the locking state position of the locking mechanism is relatively fixed, and the use of the sealing ring can ensure that the barrel cover and the barrel body form effective sealing contact, thereby better protecting the ammunition in the barrel body.

[0049] In addition, the present application has a relatively large space for the design and installation of the locking structure, and the present application integrates the locking mechanism in the narrow space of the barrel cover, solves the size requirements of the packaging barrel in the axial and radial directions, effectively saves the space, provides more space for the protection design of the contents in the packaging barrel, and improves the safety protection level of the packaging barrel. The locking mechanism also has a handle function, and the barrel cover can be removed by pulling the locking buckle when the locking buckle is opened. Moreover, the packaging barrel structure has better sealing performance and higher strength, and the locking type sealing structure is relatively difficult to realize sealing in harsh environments such as high temperature environment, low temperature environment, humid environment and impact resistance. The packaging barrel and the sealing joint can realize the sealing performance in all environments and have higher strength to provide better protection for the contents.
