Compared with the prior art, the gas storage tube and gun barrel integrated structure has the advantages that the gas storage tube and gun barrel integrated structure can only be integrated on a cartridge receiver due to the fact that the gas storage tube and gun barrel integrated structure is too compact and is small relative to a constant-pressure gas chamber, the output power of the gas gun is limited, and more functions cannot be expanded, and in the technical scheme, compared with the traditional gas storage tube and gun barrel integrated structure, the gas storage tube and gun barrel integrated structure is simple in structure and convenient to use. According to the split structure, an expansion piece can be additionally arranged at any position of the air storage pipe, the length and the size of the constant-pressure air chamber can be reasonably adjusted, the built-in gun barrel can be well supported on the middle split structure, and the stability during shooting can be improved for a long rifle gun barrel.

Description

Technical fields:

[0001] This utility model relates to the field of air gun technology, specifically to an air gun with a separate barrel and an internal air tank. Background technology:

[0002] An air gun is a low-powered gun that uses compressed air to fire small metal bullets. It is a general term for firearms that use compressed air or gas to propel projectiles. There are three main types of power sources for air guns: spring-piston, pneumatic, and carbon dioxide. They are used in both air rifles and air pistols. In the current technology, air guns that use pneumatic power to provide a power source generally have a gas storage area on the gun body. When the air gun is fired, the power source in the gas storage area enters the barrel through the gas source pipe path, providing the power to fire the bullet located in the barrel. The traditional integrated gas storage tube and barrel structure is too compact and the constant pressure air chamber is relatively small, so it can only be integrated into the receiver. The output power of the air gun is also limited, and it is not possible to expand more functions. Summary of the Invention:

[0003] The purpose of this invention is to solve the existing problems by providing a separate structure for the air gun's gas storage tube and barrel.

[0004] The technical solution of this utility model is as follows:

[0005] An air gun with a built-in air tank and a separate barrel structure includes a stock module and a trigger assembly. The stock module contains a firing device connected to the trigger assembly, and the firing device is connected to the barrel. The barrel has a first high-pressure air chamber and a second high-pressure air chamber surrounding it. A tee connector is threaded onto the end of the barrel and screwed into the first high-pressure air chamber surrounding the barrel. A reducer connector is screwed onto the front end of the first high-pressure air chamber and threaded into a blast-proof base. An adapter is also connected to the other end of the blast-proof base and screwed into the second high-pressure air chamber surrounding the barrel. The first and second high-pressure air chambers are sealed to both ends of the blast-proof base via the reducer connector and the adapter. A constant pressure device is located below the blast-proof base, and an inflation plug is screwed onto the front end of the second high-pressure air chamber.

[0006] As a preferred technical solution, the constant pressure device includes a constant pressure system, a constant pressure chamber, a high pressure gauge, a constant pressure gauge, and an exhaust valve. The constant pressure system is located inside the lower end of the explosion-proof base. The constant pressure system is connected to the constant pressure chamber, and a high pressure gauge is installed at the connection point. The other end of the constant pressure chamber is connected to the constant pressure gauge and is connected to the firing device through the exhaust valve.

[0007] As a preferred technical solution, the constant pressure air chamber is a hollow tubular component with variable volume.

[0008] As a preferred technical solution, the explosion-proof base, trigger assembly, and stock module connected to the constant pressure gas chamber are all equipped with detachable expansion components, on which additional compatible gas cylinders can be installed.

[0009] As a preferred technical solution, expansion slots are formed on the explosion-proof base, trigger assembly, and stock module, and expansion components are connected through the expansion slots.

[0010] As a preferred technical solution, a sealing strip is provided at the connection between the inflation plug and the second high-pressure air chamber.

[0011] The beneficial effects of this utility model are as follows:

[0012] In the technical solution disclosed in this utility model, compared with the traditional integrated gas tube and barrel structure, the split structure allows for the addition of extension components at any position of the gas tube, and the length and size of the constant pressure gas chamber can be reasonably adjusted. Furthermore, the built-in barrel can obtain excellent support in the split structure, which can increase the stability during shooting for longer rifle barrels. The split structure allows for the additional installation of a compatible standard gas cylinder on the extension components to increase the number of shots. The split structure allows for more elaborate designs on the explosion-proof base connecting the high-pressure gas chamber, whereas the original integrated gas tube and barrel structure could not create an extension groove on the high-pressure gas chamber, which would affect its strength. The first and second high-pressure gas chambers are sealed and connected through a tee connector, a reducing connector, an adapter, and an explosion-proof base, avoiding the airtightness problems of the split structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-5 As shown, an air gun with a built-in air tank and a separate barrel structure includes a stock module 1 and a trigger assembly 2. The stock module 1 is equipped with a firing device 3 connected to the trigger assembly 2. The firing device 3 is connected to the barrel 4. The barrel 4 is surrounded by a first high-pressure air chamber 5 and a second high-pressure air chamber 6. A three-way connector 7 is threaded onto the end of the barrel 4 and screwed into the first high-pressure air chamber 5. A reducing connector 8 is screwed onto the front end of the first high-pressure air chamber 5 and threaded into a blast-proof seat 9. The other end of the blast-proof seat 9 is connected to an adapter 10, which is screwed into the second high-pressure air chamber 6. The first high-pressure air chamber 5 and the second high-pressure air chamber 6 are sealed to both ends of the blast-proof seat 9 through the reducing connector 8 and the adapter 10. A constant pressure device 11 is provided below the blast-proof seat 9. An inflation plug 12 is screwed onto the front end of the second high-pressure air chamber 6.

[0021] Furthermore, the constant pressure device 11 includes a constant pressure system 13, a constant pressure chamber 14, a high pressure gauge 15, a constant pressure gauge 16, and an exhaust valve 17. The constant pressure system 13 is located inside the lower end of the explosion-proof base 9. The constant pressure system 13 is connected to the constant pressure chamber 14, and a high pressure gauge 15 is installed at the connection point. The other end of the constant pressure chamber 14 is connected to the constant pressure gauge 16 and is connected to the firing device 3 through the exhaust valve 17. After being separated, an extension can be added at any position on the gas storage tube, and the length and size of the constant pressure chamber 14 can be reasonably adjusted. In addition, the built-in barrel can be well supported in the middle split structure, which can increase the stability during shooting for longer rifle barrels.

[0022] Furthermore, the constant pressure chamber 14 is a hollow tubular component with variable volume. The explosion-proof base 9, trigger assembly 2, and stock module 1 connected to the constant pressure chamber 14 are all equipped with detachable expansion components 18. An additional suitable gas cylinder 19 can be installed on the expansion component 18. The explosion-proof base 9, trigger assembly 2, and stock module 1 are all formed with expansion grooves, through which the expansion component 18 is connected. The split structure allows for the additional installation of a suitable standard gas cylinder 19 on the expansion component 18 to increase the number of shots. The split structure allows for more design work on the explosion-proof base 9 connected to the high-pressure chamber. The original integrated gas storage tube and barrel structure cannot have expansion grooves made on the high-pressure chamber, which would affect the strength. The first high-pressure chamber 5 and the second high-pressure chamber 6 are sealed and connected through the tee connector 7, reducer connector 8, adapter 10, and explosion-proof base 9, avoiding the airtightness problem of the split structure.

[0023] Furthermore, a sealing strip is provided at the connection between the inflation plug 12 and the second high-pressure air chamber 6.

[0024] Working principle: The inflation plug 12 is threaded to the front end of the second high-pressure air chamber 6. The end of the second high-pressure air chamber 6 is threaded to the adapter 10. The reducer 8 is inserted into the explosion-proof seat 9 and threaded to the adapter 10. The reducer 8 is threaded to the front end of the first high-pressure air chamber 5. The barrel is threaded to the tee connector 7. The tee connector 6 is then connected to the end of the first high-pressure air chamber 5. The constant pressure device 11 is inserted into the explosion-proof seat 9 and threaded to the constant pressure air chamber 14. The other end of the constant pressure air chamber 14 is connected to the outlet valve 17. Air is filled into the inflation plug 12, enters the high-pressure air chamber, and passes through the constant pressure device 11. The pressure is reduced to the constant pressure air chamber 14 and reaches the outlet valve to form an overall seal, thus entering the ready-to-fire state. Compared to the traditional integrated gas tank and barrel structure, the structure in this application is too compact and has a relatively small constant pressure gas chamber, which can only be integrated into the receiver. This limits the output power of the air gun and prevents the expansion of more functions. After being separated, an extension can be added at any position of the gas tank, and the length (i.e., size) of the constant pressure gas chamber can be reasonably adjusted. Furthermore, the internal barrel can be well supported in the middle of the split structure, which can increase the stability during shooting, especially for longer rifle barrels.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
