Description

Technical Field

[0001] This utility model relates to the field of air gun air spring installation technology, and in particular to an air spring used in air guns. Background Technology

[0002] As a shooting device that uses compressed gas to propel projectiles, the shooting accuracy, recoil control, and overall structural durability of an air gun are key performance indicators. During the operation of an air gun, especially at the moment of firing or when subjected to external impact, the internal moving parts will experience severe shocks and vibrations. This impact not only affects the stability and accuracy of shooting, but also, over time, leads to rapid wear and even damage to internal parts (such as pistons, cylinders, and connecting parts), seriously affecting the service life and reliability of the air gun.

[0003] While a single gas spring can provide some cushioning, its cushioning characteristics are linear, and the magnitude of the cushioning force is directly proportional to the compression distance. Under instantaneous, severe impacts, its cushioning effect may be insufficient, easily resulting in rigid impacts. Furthermore, gas springs rely primarily on air pressure; if a leak occurs or the system fails, the entire cushioning system will completely fail, making it unreliable. Mechanical springs also have relatively limited cushioning effects, and their spring stiffness (hardness) is fixed. To obtain sufficient cushioning force, a stiffer spring is often required, but this increases the damping of moving parts, affecting the smoothness of movement. Additionally, a single spring is prone to reaching its limit deformation under overload impacts, leading to permanent damage or breakage.

[0004] To address the above problems, it is necessary to design a gas spring for use in air guns to overcome these issues. Utility Model Content

[0005] The main objective of this invention is to provide a gas spring for use in air guns, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A gas spring for use in an air gun includes a cylinder, a limiting block, and a rounded corner limiting block. A gas spring is connected to the top of the rounded corner limiting block, and a limiting ring is connected to the top of the gas spring. A piston is connected to the top of the gas spring through the top of the limiting ring, and a piston rod is connected to the top of the piston. A connecting rod is connected to the bottom of the gas spring through the top of the rounded corner limiting block, and an elastic ball is connected to the bottom of the connecting rod. Telescopic rods are connected to both ends of the limiting ring. A first limiting spring is fitted onto the outer wall of each of the two telescopic rods. A rounded corner limiting plate is connected to the end of each telescopic rod near the limiting ring. An inclined block is connected to the inner side of each telescopic rod through the limiting ring.

[0008] As a preferred embodiment of this utility model, the end of the telescopic rod away from the limiting ring is connected to a limiting sleeve, the end of the two limiting sleeves away from the rounded corner limiting plate is connected to a rounded corner connecting plate, the inner side of the two rounded corner connecting plates away from the limiting sleeve is connected to a second limiting spring, and the end of the two second limiting springs away from the rounded corner connecting plate is connected to a fixing block.

[0009] In a preferred embodiment of this utility model, the gas spring passes through the top of the limiting ring and is fixedly connected to the piston, the piston is rotatably connected to the piston rod, and the limiting ring is fixedly connected to the gas spring.

[0010] In a preferred embodiment of this utility model, the gas spring is fixedly connected to the connecting rod, the connecting rod is fixedly connected to the elastic ball, and the outer wall of the elastic ball contacts the outer walls of the two inclined blocks.

[0014] Beneficial effects

[0016] This air spring, used in air guns, features a limiting effect when compressed by the downward force of the piston rod. An elastic ball, also subjected to downward force, applies pressure to two inclined blocks, which in turn apply pressure to both ends, compressing the first limiting spring on the outer wall of the telescopic rod for cushioning and protection. A rounded corner limiting plate limits the connection between the telescopic rod and the limiting ring. Two limiting sleeves limit the movement of the telescopic rod. Two second limiting springs are fixed to the ends of the fixed block and the rounded corner connecting plate, extending and retracting in sync with the first limiting spring. Therefore, when the air spring is impacted and subjected to pressure, the elastic ball applies pressure to the two inclined blocks, and the first and second limiting springs provide effective cushioning and limiting.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5As shown, a gas spring for an air gun includes a cylinder 1, a limiting block 2, and a rounded corner limiting block 3. A gas spring 4 is connected to the top of the rounded corner limiting block 3, a limiting ring 7 is connected to the top of the gas spring 4, a piston 5 is connected to the top of the limiting ring 7 through the top of the gas spring 4, a piston rod 6 is connected to the top of the piston 5, a connecting rod 12 is connected to the bottom of the gas spring 4 through the top of the rounded corner limiting block 3, an elastic ball 13 is connected to the bottom of the connecting rod 12, telescopic rods 8 are connected to both ends of the limiting ring 7, a first limiting spring 10 is sleeved on the outer wall of each of the two telescopic rods 8, a rounded corner limiting plate 9 is connected to the end of the outer wall of each of the two telescopic rods 8 near the limiting ring 7, and an inclined block 11 is connected to the inner side of each of the two telescopic rods 8 through the limiting ring 7.

[0025] Gas spring 4 passes through the top of limiting ring 7 and is fixedly connected to piston 5. Piston 5 is rotatably connected to piston rod 6. Limiting ring 7 is fixedly connected to gas spring 4. Gas spring 4 is fixedly connected to connecting rod 12. Connecting rod 12 is fixedly connected to elastic ball 13. The outer wall of elastic ball 13 contacts the outer wall of two inclined blocks 11. Two inclined blocks 11 are rotatably connected to telescopic rod 8. Two telescopic rod 8 are fixedly connected to the first limiting spring 10. Both ends of limiting ring 7 are sleeved on the outer wall of telescopic rod 8 near the rounded corner limiting plate 9. Rounded corner limiting plate 9 is sleeved on the outer wall of telescopic rod 8.

[0026] Specifically, the gas spring 4, as the main buffer element, absorbs the impact force through the compression of high-pressure nitrogen gas inside the piston rod 6 when it is squeezed by downward gravity, thus playing a preliminary limiting and buffering role. After the elastic ball 13 is subjected to downward gravity, it applies pressure to the two inclined blocks 11, causing the inclined blocks 11 to move to both ends and compress the first limiting spring 10, thereby dispersing and buffering the force. The inclined blocks 11 are rotatably connected to the telescopic rod 8 to ensure smooth and unobstructed force transmission. The first limiting spring 10 is sleeved on the outer wall of the telescopic rod 8, directly absorbing the impact transmitted by the inclined blocks 11. The second limiting spring 17 is fixed between the fixed block 16 and the rounded corner connecting plate 15, and moves synchronously with the extension and retraction of the first limiting spring 10, further enhancing the buffering effect. The rounded corner limiting plate 9 limits the connection between the telescopic rod 8 and the limiting ring 7 to prevent separation or misalignment. The limiting sleeve 14 is fitted onto the end of the telescopic rod 8 away from the limiting ring 7 to ensure the accurate movement trajectory of the telescopic rod 8 and avoid lateral swaying. Due to the pressure of the elastic ball 13, the two inclined blocks 11 slide outward and upward along their inclined surfaces. This action compresses the first limiting spring 10 fitted on the outer wall of the telescopic rod 8, putting it in a stable pre-compression state.

[0027] The end of the telescopic rod 8 away from the limiting ring 7 is connected to the limiting sleeve 14. The ends of the two limiting sleeves 14 away from the rounded corner limiting plate 9 are connected to the rounded corner connecting plate 15. The inner side of the two rounded corner connecting plates 15 away from the limiting sleeve 14 is connected to the second limiting spring 17. The ends of the two second limiting springs 17 away from the rounded corner connecting plate 15 are connected to the fixing block 16.

[0028] The ends of the two telescopic rods 8 away from the rounded corner limiting plate 9 are rotatably connected to the limiting sleeve 14, and the limiting sleeve 14 is fixedly connected to the rounded corner connecting plate 15; the rounded corner connecting plate 15 is fixedly connected to the second limiting spring 17, the fixing block 16 is fixedly connected to the second limiting spring 17, and the ends of the second limiting spring 17 away from the rounded corner connecting plate 15 are fixedly connected to the ends of the rounded corner limiting block 3 away from the telescopic rods 8 through the fixing block 16;

[0029] Specifically, the second limiting spring 17, which works in conjunction with the first limiting spring 10, has its two ends connected to the rounded corner connecting plate 15 and the fixing block 16, respectively. Since the rounded corner connecting plate 15 is connected to the telescopic rod 8, and the first limiting spring 10 has been pre-compressed, the second limiting spring 17 is also in a stable state of pre-tension or pre-compression. The rounded corner limiting plate 9 and the limiting sleeve 14 respectively restrict the relative positions of the telescopic rod 8, the limiting ring 7, and the end of the telescopic rod 8, ensuring that all components are in the correct designed position in the initial state without shaking.

[0030] It should be noted that this utility model is a gas spring applied to an air gun. When in use, when the air gun is fired or subjected to a downward impact, the huge impact force is transmitted to the entire system through the piston rod 6. The piston rod 6 is subjected to the downward impact force, moves downward and further compresses the gas spring 4. The gas inside the gas spring 4 is rapidly compressed, and its huge reaction force begins to absorb and convert most of the impact energy. This is the first and most important line of defense, which effectively reduces the peak of the impact. The limiting ring 7 transmits the downward force to the elastic ball 13, which makes it apply stronger pressure to the two inclined blocks 11. Under stronger pressure, the two inclined blocks 11 move outward and upward along their inclined surfaces, generating greater displacement. This action converts the vertically downward impact force into a horizontal thrust through the inclined plane principle, and at the same time realizes the amplification of the force. The outward and upward movement of the inclined blocks 11 will compress the first limiting spring 10 sleeved on the outer wall of the telescopic rod 8. The first limiting spring 10 begins to absorb and store the impact energy converted from the inclined blocks. This is the second level of buffer, which is mainly responsible for refining and absorbing the remaining impact.

[0031] The movement of the telescopic rod 8 causes the rounded corner connecting plate 15 to move, thereby stretching or compressing the second limiting spring 17. The second limiting spring 17 and the first limiting spring 10 work together to form a composite spring buffer system, which shares the impact load and absorbs more energy, making the buffering process smoother and more thorough, effectively preventing rigid impacts. Throughout the movement, the rounded corner limiting plate 9 ensures that the telescopic rod 8 and the limiting ring 7 will not separate or misalign; the limiting sleeve 14 ensures that the movement trajectory of the telescopic rod 8 is always accurate, preventing it from bending or lateral swaying, and ensuring the stability and reliability of the buffering process. After the impact force disappears, the entire system enters the reset phase. The compressed first limiting spring 10 and second limiting spring 17 begin to release their stored elastic potential energy, pushing their respective components to move in the opposite direction. The first limiting spring 10 pushes the telescopic rod 8 and the inclined block 11 to move inward and downward. The inclined block 11 is released from the strong pressure on the elastic ball 13. At the same time, the compressed gas spring 4 also begins to expand, pushing the piston rod 6 to move upward and restore its initial height. Under the guidance of the rounded corner limiting plate 9 and the limiting sleeve 14, all components finally return to the initial static state of the first step, and the entire system is ready to receive the next impact or firing.
