Description

Pneumatic toy gun and top-spin rubber

The new model relates to a pneumatic toy gun, which is especially used for spinning rubber on the pneumatic toy gun.

In recent years, survival games that use safety firearms for combat have become more and more popular. The firearms used are mainly pneumatic toy guns, and the bullets used are mainly non-metallic spherical projectiles (non-metallic spherical projectile), or can Called BB bombs.

After a pneumatic toy gun fires a bullet, since the bullet will be affected by air resistance and gravity during flight, its flight trajectory will gradually deviate from a straight line after a certain distance. In view of this, the conventional technology proposes to add a hop-up bucking to the pneumatic toy gun, which contacts the BB bullet when the BB bullet is in the firing position, so that the BB bullet is ejected due to the top-up bucking rubber. The friction between the BB bomb and the BB bomb causes upward rotation (topspin or backspin). Based on Bernoulli's Principle, when the BB bomb flies in a spin mode, the air passing through the lower part of the BB bomb is due to the The same direction of rotation will result in a smaller flow rate. On the contrary, when the air passes through the upper part of the BB bomb, the flow rate will be larger because it is in the opposite direction of rotation. At this time, the air will produce a slight buoyancy on the BB bomb, which can greatly slow down the descent of the BB bomb. Speed increases range.

Regarding the structure of the conventional top-spin rubber, whether it is a triangular or pentagonal design, the main goal is to have sufficient contact area with the BB bullet to ensure that it can provide the friction force to the fired BB bullet to cause it to rotate upward.
