Piston type power mechanism of air gun

Abstract

The invention discloses a piston type power mechanism of an air gun. The piston type power mechanism comprises a gun barrel, wherein an air spring is arranged in the gun barrel and comprises an air cylinder, nitrogen and a piston are arranged in the air cylinder, the air spring is arranged in the gun barrel in the reverse direction, the air spring is arranged in the gun barrel in the reverse direction, and a piston rod of the piston abuts against an air spring base. According to air gun, the internal piston is driven by the piston rod to compress the internal nitrogen so that energy storage can be achieved; the piston rod and the air spring are strictly coaxial in appearance, and therefore the problem of shaking and the like does no exist in the working process, the stability of the air spring is far better than that of a steel wire spring, and vibration and noise of the air gun are greatly reduced. On the basis that the air spring serves as a power source, by taking the gravity center position of the air spring and the overall working condition into consideration, practical shooting test comparison is conducted on forward installation and backward installation of the air spring, finally, the air spring is arranged in the reverse direction through analysis and comparison, and therefore the initial shooting speed is slightly increased, and stability of the initial speed is greatly improved.

Description

technical field [0001] The invention relates to the field of firearms, in particular to a power mechanism of an air gun. Background technique [0002] Existing piston air guns in the market generally use steel wire springs as the power source, and rely on compressed steel wire springs to store energy. The energy of lead bullets. [0003] It has the following defects: [0004] 1. In the compressed state, the wire spring will produce shape changes: irregular axial bending and radial enlargement. During the release process, that is, the process in which the deformation returns to its original state in a short period of time. Since the spring returns to its original state quickly and in a short time, the spring must vibrate during the recovery process, causing the spring to collide with the inner wall of the gas cylinder, causing the firearm to vibrate. , and this kind of vibration occurs before the bullet leaves the gun. It is conceivable that the aiming point (aiming baseli...

During the release process, that is, the process in which the deformation returns to its original state in a short period of time. Since the spring returns to its original state quickly and in a short time, the spring must vibrate during the recovery process, causing the spring to collide with the inner wall of the gas cylinder, causing the firearm to vibrate. , and this kind of vibration occurs before the bullet leaves the gun. It is conceivable that the aiming point (aiming baseline) that was carefully searched for is destroyed or changed, and the impact point will be affected to varying degrees, which is what we call shooting accuracy. Difference

[0005] 2. The length of the steel wire spring, the number of effective turns and the diameter of the steel wire determine the initial velocity of the bullet. When different initial velocities are required, we need to use theoretical formulas to calculate the above spring parameters, and then use a standard speedometer to detect the initial velocity of the bullet through live ammunition shooting to determine the optimal velocity. Optimum parameter value, more cumbersome and complicated in actual production
