Description

Technical fields:

[0001] This utility model relates to the field of air gun technology, specifically a thin-walled barrel structure for an air gun. Background technology:

[0002] The air gun barrel is the path a bullet must take when fired, serving functions such as silencing and keeping the bullet as level as possible. In existing technologies, air gun barrels are generally exposed, with conventional air gun barrels having an outer diameter greater than 12mm. Furthermore, the rifling used to keep the bullet level is complex to manufacture, requiring several steps including deep hole drilling, sprue finishing, extrusion finishing, and wire extrusion. Traditional integrated barrel and gas tank structures, or traditional separate barrel and gas tank structures, often result in excessive pressure on thin-walled barrels, exceeding 250 brane pressure, and the pressure continuously decreases after each shot. The air pressure acting on the thin-walled barrel varies with each shot, which is detrimental to accurate shooting. Chinese patent CN201520857454.0 discloses a thin-walled air gun barrel, but the patent only discloses the outer diameter range of the barrel body and does not provide an effective solution to the aforementioned problems. Summary of the Invention:

[0003] The purpose of this invention is to solve the existing problems by providing a thin-walled barrel structure for an air gun.

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

[0005] A thin-walled barrel structure for an air gun includes a thin-walled long barrel, a stock assembly, and a firing device. A constant-pressure air chamber is fixedly enclosed around the thin-walled long barrel. An air chamber plug is threaded to the front end of the constant-pressure air chamber, and a four-way connector is threaded to the rear end of the constant-pressure air chamber. The thin-walled long barrel is threaded to the middle of the four-way connector, and a constant-pressure system is sealed to the end of the four-way connector. The constant-pressure system is threaded to the firing device, and the constant-pressure system is connected to an air outlet valve and an air filling seat. The air filling seat can be connected to a gas cylinder with a standard interface diameter.

[0006] As a preferred technical solution, an extension block is provided at the connection between the thin-walled long barrel and the stock assembly, and an additional standard gas cylinder can be installed on the extension block.

[0007] As a preferred technical solution, the connection between the constant pressure air chamber and the air chamber plug is sealed by a sealing ring.

[0008] As a preferred technical solution, the stock assembly is fixed to the thin-walled long barrel by screws, including at least two screws, and all screws are symmetrically distributed at equal intervals along the central axis of the thin-walled long barrel.

[0009] As a preferred technical solution, the thin-walled long barrel is fixedly connected to the stock assembly through a constant pressure gas chamber. The outer diameter of the constant pressure gas chamber ranges from 9mm to 12mm, and the inner diameter ranges from 5.5mm to 7.5mm.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model patent uses a constant pressure air chamber to enclose the gun barrel. Compared with the traditional suspended gun barrel that is exposed, especially the thin-walled long gun barrel, which is deformed after collision during use due to its thinness in order to reduce weight, thus affecting shooting accuracy, this fixing method of enclosing the gun barrel with a constant pressure air chamber is very strong. After pressure is formed inside, it can evenly enclose the gun barrel and provide stable support.

[0012] 2. This utility model can effectively solve the problem of decreased accuracy after multiple shots by using a constant pressure internal fixing method. Within the effective number of shots, the pressure on the barrel is consistent and does not change, thereby improving the consistency of each shot.

[0013] 3. Compared with traditional external gas cylinder air guns, it has a significant advantage in gas capacity. It utilizes the space of the barrel to achieve highly accurate suspension and fixation, and it is stronger than traditional suspension and fixation. It also has a larger constant pressure gas chamber, thereby increasing the effective number of shots. Attached image description:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, a thin-walled barrel structure for an air gun includes a thin-walled long barrel 1, a stock assembly 2, and a firing device 3. A constant pressure air chamber 4 is fixedly wrapped around the thin-walled long barrel 1. An air chamber plug 5 is threaded to the front end of the constant pressure air chamber 4, and a four-way connector 6 is threaded to the rear end of the constant pressure air chamber 4. The thin-walled long barrel 1 is threaded to the middle of the four-way connector 6, and a constant pressure system 7 is sealed to the end of the four-way connector 6. The constant pressure system 7 is threaded to the firing device 3, and the constant pressure system is connected to an exhaust valve 8 and an inflation seat 9. The inflation seat 9 can be connected to a standard-diameter air cylinder 10.

[0021] Furthermore, an extension block 11 is provided at the connection between the thin-walled long barrel 1 and the stock assembly 2. An additional standard gas cylinder can be installed on the extension block 11 to increase the number of shots.

[0022] Furthermore, the connection between the constant pressure air chamber 4 and the air chamber plug 5 is sealed by a sealing ring 12. The fixing method of being wrapped by the constant pressure air chamber 4 is very firm. After pressure is formed inside, it can evenly wrap the barrel to provide stable support.

[0023] Furthermore, the stock assembly 2 is fixed to the thin-walled long barrel 1 by screws, including at least two screws, and all screws are symmetrically distributed at equal intervals along the central axis of the thin-walled long barrel 1.

[0024] Furthermore, the thin-walled long barrel 1 is fixedly connected to the stock assembly 2 via a constant pressure gas chamber 4. The outer diameter of the constant pressure gas chamber 4 ranges from 9mm to 12mm, and the inner diameter ranges from 5.5mm to 7.5mm.

[0025] Working principle: The thin-walled barrel structure of this utility model of an air gun has a constant pressure air chamber 4 wrapped around the outer surface of the thin-walled long barrel 1. The air pressure inside the constant pressure air chamber 4 is constant, and the thin-walled long barrel 1 is sealed and wrapped inside. After the pressure is formed inside, it can evenly wrap the barrel and provide stable support. This fixed method with constant pressure can effectively solve the problem that the pressure continuously drops after each shot in the traditional integrated barrel and air tank structure or the traditional separate barrel and air tank structure, and the change in air pressure leads to a decrease in shooting accuracy.

[0026] 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.
