[0028] The utility model discloses a magazine with a high-pressure inflation interface, comprising a magazine component, a deflation valve component and an inflation seat component. The magazine component is provided with an air outlet structure and a sealing structure. The air outlet structure is provided at the top of the magazine and fixed by a cylindrical pin, and the sealing structure is provided at the top of the expansion chamber on one side of the magazine. The deflation valve component is installed on the side of the magazine body and is sealed by a threaded connection. After the deflation valve component is struck by an external force, the air valve is opened to deflate once. After the external force is removed, the deflation valve component is reset and closed under the action of the high-pressure gas and the deflation valve spring. This deflation closing movement cycle occurs to complete the periodic energy supply and shooting. The inflation seat component is installed at the bottom of the magazine body and has a one-way gas inflow function. High-pressure gas can be inserted into the bottom of the inflation seat through the inflation nozzle, and the gas flow pushes open the check valve and is filled into the magazine body. Each time the gas is filled, the pneumatic pistol-type training gun can be shot 20 times.

[0029] Furthermore, the air outlet structure is arranged at the top of the magazine and fixed by a cylindrical pin. The air outlet glue and the air outlet glue seat are positioned in the positioning groove of the magazine body. The air outlet glue seat is flush with the top surface of the magazine body. The air intake and sealing effect are achieved by the air outlet glue and the air inlet being compressed and deformed.

[0030] Furthermore, the sealing structure is arranged at the top of the expansion chamber on one side of the magazine, and the expansion chamber is arranged on one side of the inner cavity of the magazine body. The upper plug is inserted into the threaded hole of the expansion chamber of the magazine body and is tightened and sealed by an O-ring to expand the magazine body.

[0031] Furthermore, the deflation valve component is mounted on the side of the magazine body and is sealed by a threaded connection. The deflation valve component opens the air valve after being struck by an external force, deflates air once, and after the external force is removed, it is reset and closed under the action of the high-pressure gas and the deflation valve spring. This deflation and closing movement cycle occurs to complete periodic energy supply and shooting.

[0032] Furthermore, the inflatable seat component is installed at the bottom of the magazine body and has a one-way gas inflow function. High-pressure gas can be inserted into the bottom of the inflatable seat through the inflating nozzle, and the gas flow pushes the check valve open and then fills into the magazine body. Each time the gas is filled, the pneumatic pistol training gun can be shot 20 times.
