Description

Adjustable up-spin device with guide groove

This creation is about an adjustable top-spin device with guide grooves, especially the main body contains concave-shaped protrusions and strip-shaped protrusions.

Press, a toy gun is a toy with the appearance of a firearm. Some use batteries as power and produce sound and light effects when the trigger is pulled down, while some can fire less lethal plastic bullets through compressed air or a little gunpowder. Taiwan is one of the regions with a booming toy gun industry, and has a market share of 50% in the toy gun market worldwide.

With the development of the times, toy guns have also evolved into shooting sports, "survival games", which is a semi-competitive modern shooting game similar to paintball. Survival games are mainly air guns, gas guns or electric guns that fire BB bullets. No matter what form of toy guns, the main purpose is to allow users to experience the thrill of shooting in a safe environment. Through toy guns Imitating the dimensions of real guns, allowing users to experience it all, thereby enhancing the overall entertainment effect.

The barrel of a toy gun is mainly used as a channel for inserting and ejecting bullets (commonly known as BB bullets). In view of cost and structural complexity considerations, there is no spiral (commonly known as rifling) that can guide the rotation of the bullet in the barrel. The structure, therefore, also causes the trajectory of non-directional rotation after the bullet of the toy gun is fired, which is difficult to control.

Moreover, bullets have different weights during production, and the round diameters of bullets produced by different manufacturers have slight tolerances, and bubbles are generated when the bullet is fired, so that it is not evenly placed in the center of the bullet.

Toy guns generally used for BB bullets, such as gas guns, air guns, electric guns, etc., are usually equipped with a top-spin ballistic device (HOP UP). The principle of the so-called top-spin ballistic device is to use the principle of rotation to use the shot BB bullets. The friction causes the BB to spin up when it ejects. The power of this topspin will offset the gravity effect of launching, so that the BB projectile can continue to fly in a straight line, and the topspin ballistic device is usually built on the barrel end of the toy gun. Therefore, the main purpose of the top-spin ballistic device is to increase the range, because the spherical BB bullet in the barrel is given a forward "rolling" force. In aerodynamics, the air velocity increases and the pressure decreases. The speed difference between the upper part of the rolling ball and the air increases, so an upward force is generated, which can generally extend the range by at least ten meters.

The conventional top-spin ballistic device uses a tubular rubber to cooperate with a presser (commonly known as a dog bone). When the trigger is pulled, the tubular rubber is pressed down by the presser to form proper friction with the BB bullet, so that the BB bullet Top spin to increase range. However, the conventional tubular rubber is designed with a single-point downward pressure structure, or it may not be accurately positioned during installation, or it may be easily deflected after a period of use, which will affect the effect of top-spin. It needs to be effectively improved.

The purpose of this creation is to provide an adjustable top-spin device with a guide groove for installation in a toy gun, including a main body, a protruding part, a concave-shaped protrusion and a strip-shaped protrusion, wherein the main body is a hollow cylinder , Is divided into an inner circumferential surface and an outer circumferential surface, the protruding part is located at the bottom of the outer circumferential surface of the main body, and the concave-shaped protrusions and the strip-shaped protrusions are all located on the inner circumferential surface of the main body.

The inner circumferential surface of the main body further includes a first inner ring and a second inner ring. The first inner ring and the second inner ring are formed by extending inwardly from the inner circumferential surface of the main body. The first inner ring serves as a concave convex and a strip-shaped protrusion The base, concave-shaped protrusions and strip-shaped protrusions all extend from the first inner ring to the top of the main body.

The top of the main body further has an outlet ring.

Preferably, the concave-shaped protrusions and the strip-shaped protrusions are located at corresponding positions, which are 180 degrees apart on the inner circumferential surface, and the concave-shaped protrusions have guide grooves.

Preferably, the concave-shaped bump extends from the first inner ring to the top without touching the outlet ring. At the same time, the thickness of the concave-shaped bump gradually decreases, and the width and depth of the guide groove are in the concave-shaped convex The block thickness remains unchanged while decreasing.

Preferably, the caliber of the first inner ring is smaller than that of the second inner ring, and there is a gap between the first inner ring and the second inner ring.
