Description

Technical Field

[0001] This utility model relates to a stabilizing structure for a musket, belonging to the field of air gun technology. Background Technology

[0002] Air guns fire by using a power source to power the bullets inside. As the demand for recreational use of air guns has increased, designs like the one disclosed in CN208688333U, which uses an arrow body instead of a cartridge case, have emerged. However, this type of air gun requires the arrow body to be installed inside the barrel. High-pressure gas is injected into the barrel to propel the arrow. To prevent air leakage from affecting the firing performance, the arrow body must be designed without tail fins. This affects the stability and accuracy of the arrow after firing. Therefore, designs with tail fins have been developed for firing arrows. The air gun structure includes a finned arrow body comprising a hollow shaft with an open rear end, an arrowhead at the front end, and fins on the outer wall of the shaft. The air gun includes an inner and outer tube, one end of which is connected to an air inlet sleeve. The outer wall of the air tube has a sealing element that mates with the inner wall of the arrow shaft. In use, the arrow body is fitted onto the air tube, positioned between the air tube and the outer tube. To ensure the arrow body is stably fitted onto the air tube, the air tube is relatively long. Since only one end of the air tube is fixed, it is prone to significant swaying when the arrow body is fired. The outer tube provides limited restraint for the arrow body, resulting in low stability after the arrow body is fired, which affects shooting accuracy. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a stable structure for arrows and lances, which can improve the stability and accuracy of arrow flight and overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a stable structure for a musket, used for firing an arrow with a tail fin. The arrow with a tail fin has a hollow shaft with one open end. The musket includes an inner and outer tube with an air pipe connected to an air inlet sleeve at one end. The outer wall of the air pipe is provided with a sealing element that seals against the inner wall of the arrow. The air inlet sleeve has an air inlet channel that communicates with the air pipe and is connected to a power air source. It also includes a support sleeve, which is installed between the air pipe and the outer tube. One end of the support sleeve is connected to the air inlet sleeve, and the other end is connected to the outer tube. The support sleeve has a through hole for inserting the arrow into which it is coaxially distributed with the air pipe. The through hole has a spline-shaped cross-section and provides fitting and limiting of the arrow shaft and tail fin of the arrow.

[0005] Further, it includes a support plate, one end of which is connected to the outer tube via the support plate. The support plate seals the space between the support sleeve and the outer tube. The air tube is shorter than the outer tube and the support sleeve. The side wall of the support sleeve has several air outlets that communicate with the through hole. The air outlets are close to the air outlet of the air tube. The outer tube has several exhaust holes.

[0006] Furthermore, the exhaust port is located away from the end of the support plate.

[0007] By implementing this utility model, a support sleeve for limiting the arrow body is set between the outer tube and the air tube. Since both ends of the support sleeve are connected, the support sleeve can stably limit the arrow body, thereby improving the stability and accuracy of the arrow body after firing.

[0014] Embodiments of this utility model: such as Figures 1 to 5 As shown, a stabilizing structure for a musket is provided for firing an arrow with a tail fin. The arrow with a tail fin has a hollow shaft with one open end. The musket includes an inner and outer tube 2 and an outer tube 3, both with one end connected to an air inlet sleeve 1. The outer wall of the air tube 2 is provided with a sealing element that seals against the inner wall of the arrow. The sealing element is a sealing ring 4 made of a material with a low coefficient of friction, such as PTFE, and is installed near the air outlet of the air tube 2 by a nut. The air inlet sleeve 1 has an air inlet 5 that communicates with the air tube 1 and is connected to a power air source. This application also includes a support sleeve 6, which is installed between the air tube 2 and the outer tube 3. One end is connected to the air inlet sleeve 1, and the other end is connected to the outer tube 3. The support sleeve 6 has a through hole 8 for inserting the arrow body and is coaxially distributed with the air tube 2. The through hole 8 has a spline-shaped cross section and cooperates to limit the arrow shaft 9 and tail fin 10 of the arrow body. When in use, the arrow body is sleeved outside the air tube 2, and the trigger is pulled once. The power air source releases a certain amount of high-pressure gas, which enters the air tube 1 through the air inlet 5 and fires the arrow body 1. The support sleeve 6 is located on the periphery of the arrow body and limits the arrow shaft 9 and tail fin 10. Since the support sleeve 6 is connected at both ends, it can stably limit the arrow body, thereby improving the stability and accuracy of the flight after the arrow body is fired.

[0015] As a preferred embodiment, the support sleeve 6 is connected to the outer tube 3 via the support plate 11. The support plate 11 seals the space between the support sleeve 6 and the outer tube 3. The air tube 2 is shorter than the outer tube 3 and the support sleeve 6. Several air outlets 12 communicating with the through holes 8 are provided on the side wall of the support sleeve 6. The air outlets 12 are close to the air outlets of the air tube 2. Several exhaust holes 13 are provided on the outer tube 3. When the arrow is fired and leaves the air tube 2, the high-pressure gas is discharged from the air outlet of the air tube 2, producing a loud noise. By providing air outlets 12 on the support sleeve 6, the high-pressure gas can diffuse rapidly after being discharged from the air outlet of the air tube 2. Since the support plate 11 blocks the front end of the outer tube, the gas diffuses in the outer tube 3 and is then discharged through the exhaust holes 13, thus achieving the effect of noise reduction.

[0016] As a preferred option, the exhaust port 13 is located away from the end where the support plate 11 is set, and the larger space is then discharged through the exhaust port 13, further improving the noise reduction effect.
