[0029] Specifically, the shell I 1 and the shell II 2 are assembled, the overall installation of the main shell is completed, then the valve needle 9 is loaded into the main shell, the valve needle 9 top end penetrates into the position of the gas hole 01, then the base 4 is loaded at the end of the shell II 2, and the valve needle 9 end is arranged in position with the movable through hole 02, during this period, the sealing ring 10 corresponding to the inner wall of the gas hole 01 and the movable through hole 02 at the connection of the shell II 2 and the base 4 is installed in position, after filling and loading, the bullet 8 is loaded into the cartridge 7, and then the cartridge 7 loaded with the bullet 8 is loaded into the upper receiving cavity, the sealing baffle 3 is filled and installed to seal the opening at the top of the main shell, and the overall shotshell is assembled;

[0030] As shown in Figures 5-9 , the valve needle 9 includes a needle rod 91, a lower connecting rod 92 fixedly arranged at the bottom of the needle rod 91, and an upper connecting rod 93 fixedly arranged at the top of the needle rod 91. A sealing cylinder 94 is fixedly arranged at the top end of the upper connecting rod 93. A gas collecting cavity 95 is arranged in the sealing cylinder 94. A gas passing hole 96 is arranged through the outer wall of the sealing cylinder 94 on one side. The outer diameter of the needle rod 91 is larger than the outer diameter of the lower connecting rod 92, and the outer diameter of the lower connecting rod 92 is equal to the inner diameter of the movable through hole 02. The outer diameters of the sealing cylinder 94 and the needle rod 91 are both larger than the outer diameter of the upper connecting rod 93. The outer diameter of the sealing cylinder 94 is equal to the inner diameter of the gas hole 01, and the outer diameter of the needle rod 91 is larger than the inner diameter of the gas hole 01.

[0031] As shown in Figure 4 , the sealing baffle 3 is clamped at the opening at the top of the shell I 1. The cartridge 7 includes a loading cylinder 71. The inner diameter of the loading cylinder 71 is larger than the outer diameter of the bullet 8. The concave spherical bottom plate 72 is fixedly arranged at the bottom of the loading cylinder 71.

[0032] The embodiment is specifically: through the three steps of the gas-filled shotshell from before filling gas to after launching and the position cooperation of the internal parts, mainly the influence of the movement of the valve needle 9 on the gas filling and discharging, the function is introduced:

[0033] Gas filling:

[0034] As shown in Figure 7 , after the shell assembly after loading the shell I 1, the shell II 2, the base 4 and the valve needle 9, the valve needle 9 is pulled down, during which the lower connecting rod 92 moves downward along the movable through hole 02, and the sealing cylinder 94 moves downward along the gas hole 01, to ensure that the valve needle 9 is pressed into position, so that the position of the gas passing hole 96 moves to the position of being in communication with the gas storage chamber 6. The gas storage chamber 6 is in communication with the upper receiving cavity through the gas passing hole 96 and the gas collecting cavity 95. The special gas filling tool is used to work at the position of the upper receiving cavity, so that the compressed gas is filled into the gas storage chamber 6 through the gas passing hole 96 and the gas collecting cavity 95. After a certain time of gas filling, the gas pressure display assembly of the gas filling tool reads the termination of the gas filling. The valve needle 9 is pushed up to move the end of the lower connecting rod 92 to the position of being flush with the end of the movable through hole 02 (as shown in Figure 8The middle arrow indicates the state, and the sealing ring 10 seals the gas storage chamber 6 in this state, and the inflation work is completed.

[0035] Loading the projectile:

[0036] The upper receiving cavity in the completed inflation shell is first loaded with the projectile holder 7, then the appropriate amount of projectile 8 is filled in the inner cavity of the projectile holder 7, and then the sealing baffle 3 is assembled, and the projectile loading is completed (as shown in Figure 8 The state), the inflatable shot can be fired;

[0037] Firing:

[0038] As Figure 9 shown, when the projectile-loaded inflatable shot is fired, the valve needle 9 in the middle of the base 4 is impacted, and the valve needle 9 moves to the position where the upper connecting rod 93 overlaps the dispersing hole 01 (the specific position is shown in Figure 9 ), because the dispersing hole 01 and the upper connecting rod 93 form an airflow channel, and the position of the movable hole 02 at the bottom is still sealed by the lower connecting rod 92 and the sealing ring 10, the compressed gas in the opening gap of the gas storage chamber 6 is discharged from the airflow channel at the position of the dispersing hole 01, and impacts on the concave spherical bottom plate 72. The concave spherical bottom plate 72 has a larger force area relative to the flush bottom surface, and the concave spherical bottom plate 72 of the spherical surface is uniformly impacted by the compressed gas, which ensures the stability of the gas release during the firing process, avoids premature or delayed deviation of the trajectory, and pushes the projectile holder 7 together with the projectile 8 to impact and high-speed launch the sealing baffle 3.

[0039] The above is the complete use process of the inflatable shot.

[0040] Through the structure of the inflatable shot, because there is no addition of gunpowder, the projectile holder 7 in the present scheme can be replaced by a non-metal material (such as an integrated low-pressure polyethylene structure) with a lighter mass instead of a traditional metal projectile holder. The gas pressure is used to achieve uniform distribution and stable separation of the projectile 8, solving the inconsistent separation problem of the split projectile holder. Light gas (such as compressed air or carbon dioxide) is used as the projectile holder medium to replace the traditional gunpowder, reducing the weight of the projectile body and production cost, and improving the portability;

[0041] Compared with the shot ammunition in the prior art, the inflatable shot can not only be particularly applied to air gun shooting sports, but also be used as non-lethal ammunition in riot dispersal operations. Because the structure of the inflatable shot has no primer, gunpowder, and other high-impact expansion and explosion characteristics, and the shell after use can continue to be used, only by repeating the inflation and projectile loading process and using the sealing baffle 3 to block, a new inflatable shot can be assembled, which can be reused. Combined with gas dynamics and lightweight design, it provides a more efficient and multi-purpose ammunition solution for military, police and other fields.

[0042] Finally should be explained a few points is: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broad, can be mechanical or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change;

[0043] Second: the utility model discloses the embodiment in the drawing, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, under the condition of not conflicting, the same embodiment and different embodiments of the utility model can be combined with each other;

[0044] Finally: the above only for the preferred embodiment of the utility model has, and does not for limiting the utility model, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
