Abstract

(57) [Summary] [Purpose] Regarding the barrel of a rifle or a shotgun with a rifle, an object of the present invention is to provide a barrel of a rifle or a shotgun with a rifle that has significantly improved accuracy and durability of the barrel. [Structure] 1) A guide portion having a diameter larger than that of a bullet is provided at a tip portion of a rifle portion provided with a rifle in a barrel portion of a barrel. 2) It is characterized in that the ratio of the rifle part to which the life ring is applied to the barrel part of the barrel and the guide part is 3: 1 to 2. 3) The end of the life ring on the chopped side is tapered so that the diameter is reduced toward the life ring. [Effect] A rifle and a shotgun with a rifle that have very good accuracy because they eliminate the anxiety that it is difficult to aim due to the shortening of the barrel, and there is no drawback that the accuracy of hitting deteriorates due to vibration of the entire barrel. Can provide the barrel.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is directed to a rifle (a hunting gun having a rift ring-life ring in the cavities, in which the cavities have more than 1/2 of the length of the cavities ... With regard to the barrel of the gun, the aim is to provide a barrel of a rifle and a shotgun with a life ring, which has greatly improved accuracy and durability of the barrel.

[0002]

[Prior art]

 The conventional rifle has a structure as shown in FIG. That is, the rifle 13 is provided with a life ring 14 extending to the tip of the barrel portion 12 of the barrel 11. In the figure, 15 is a sight and 16 is a star.

[0003]

[Problems to be solved by the device]

 In a rifle with such a structure, it has been conventionally known that if the barrel is long, an explosion recoil and a shock wave are generated when a bullet is fired, and the entire barrel vibrates, resulting in poor accuracy.

Therefore, it has been attempted to thicken the barrel or shorten the barrel, but if the barrel is thick, it becomes heavy and difficult to handle, and if the barrel is shortened, the distance between the aim and the star is narrowed and the aim is reduced. There was a drawback that it was difficult to match.

[0007] Furthermore, the rifle has a drawback in that the accuracy of hitting the shot with a large number of shots gradually decreases, and during such use, wear and corrosion of the tip end of the rifle nicks occur. Is called erosion.

Further, the muzzle is processed into a cross-sectional shape as shown in FIGS. 4 (a) to 4 (e) in order to improve the accuracy of hitting. The reason why so many kinds of crowns are used is that a lot of strict conditions are required for the mechanism of the gun in order to improve the accuracy when hitting a single bullet. The most important of these is the shape of the muzzle cross section. In other words, the design of the crown determines the accuracy of the hit accuracy only at the final contact point where the bullet leaves the barrel. However, such processing is very troublesome, and it is very difficult to demonstrate how effective it is.

The present invention is intended to solve the above-mentioned drawbacks of the conventional example, eliminates the fear that it is difficult to aim due to the shortened barrel, and has a very good accuracy in hitting a rifle and a rifle. It aims to provide the barrel of a shotgun.

[0008]

[Means for Solving the Problems]

 That is, the barrel of the rifle and the shotgun with a rifle of the present invention is characterized in that a guide portion having a diameter larger than that of a bullet is provided at the tip of the rifle portion of the barrel that has a rifle in the cavity. It is what

Further, the present invention is also characterized in that the ratio of the rifle portion to which the life ring is applied to the barrel portion of the barrel and the guide portion is 3: 1 to 2.

Further, one of the characteristics is that the end of the life ring on the chopped side, that is, the tip of the actual-packaging loading is tapered so that the diameter is reduced toward the life ring.

[0011]

[Action]

 Since the barrel of the rifle and the shotgun with rifle of the present invention is configured as described above, it eliminates the anxiety that it is difficult to aim due to shortening the barrel, and the entire barrel vibrates, resulting in poor accuracy. Since it has no defects, it can provide a barrel of a rifle and a shotgun with a rifle that has very good accuracy.

Further, in order to improve the accuracy of hitting, it is not necessary to specially process the muzzle, and the cost can be greatly reduced.

Further, since the structure for preventing the occurrence of erosion is adopted, the durability can be dramatically improved.

[0014]

【Example】

 An embodiment of the barrel of a rifle and a shotgun with a rifle of the present invention will be described below with reference to the drawings.

FIG. 1 shows a barrel 1 of a rifle gun 10. A guide portion 4 having a diameter larger than that of a bullet 5 is provided at a tip portion of a rifle portion 3 having a rifle on a barrel portion 2 of the barrel 1. is there. The diameter of this guide portion 4 may be increased by 1 mm or less with respect to the rifle portion 3 as long as it does not touch the fired bullet, and there is no explosion recoil or shock wave, and the entire barrel is There is no possibility of vibrating and degrading accuracy.

FIG. 2 is a view for explaining what kind of problems the fired bullet travels in the barrel while including the problems. When the top 6 is rotated, by the time the stable rotation as shown in FIG. 2 (a) is reached, the rotation shaft 7 as shown in FIG. It shifts to the stationary rotation as shown in FIG.

Similarly, within the barrel 1 of the rifle 10, the bullet 5 flies while swinging as well as rotating by the life ring after the life ring is finished and when the bullet 5 is fired from the muzzle 8. Then, when it rotates stationary, since it has already landed on the arrival position of the bullet 5, it is impossible to obtain the accuracy of the hit.

The present invention is characterized in that this swinging rotation is prevented by the guide portion 4 in FIG. 1 so that a dramatically improved hit accuracy can be obtained. Even if the bullet 5 comes into contact with the guide portion 4 due to the swaying rotation, the rotation of the bullet 5 in the polished barrel 1 does not hinder the rotation or slow the rotation.

In addition, in order to improve the accuracy of hitting the muzzle 8 along with the function of preventing the wobbling rotation of the guide portion 4, the cross-sectional shape as shown in FIGS. It becomes unnecessary.

It is desirable that the ratio of the rifle portion 3 having the life ring of the barrel portion 2 of the barrel 1 to the guide portion 4 is 3: 1 to 2. When this ratio is less than 3: 1, the meaning of providing the guide section 4 is lost, and when it exceeds 3: 2, the rifle section 3 becomes short and the bullet cannot be reliably rotated. I will end up.

The cut-side end of the life ring, that is, the actual-packet loading front end is processed into a taper 9 so that the diameter thereof is reduced toward the life ring of the rifle portion 3. This is to prevent the erosion, which is caused by the wear and corrosion of the tip of the rifle when the rifle 10 is being used, absorbed and prevented in this part, and the accuracy of the rifle 10 that has shot a large number of bullets gradually increases. It eliminates the drawback of lowering.
