Description

{CARTRIDGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bullet, and more particularly, to a bullet having a limited range after a trigger.

The bullets that are loaded into the guns and used for the purpose of killing basically can be used for practical situations as well as for training in special occupations such as police and soldiers. Recently, bullets such as clay target shooting .

Existing patents relating to bullets are generally bullets which are largely devoted to their original destruction purposes and which increase the effective range, such as the punctured warheads disclosed in the published patent application No. 10-2009-0087160, There is a case where the warhead is rotated in order to increase the lashing force, such as the self-rotating warhead disclosed in US-A-0032756, and a hollow shell in which a hole is formed in the warhead to increase the lashing force as in US2006 / 0144280 has been disclosed.

In FIG. 1, a basic bullet is shown, and the cartridge 10 includes a bullet 20 (or a warhead), a bullet 20, and other bullet 10 A propellant 40 containing a gunpowder acting as a propellant, a rim 50 covering the bottom of the bullet 10, and a charge 40, A primer 60 for igniting, and the like. When the firing pin of the gun fires the rim 50, the primer 60 is ignited and the charge 40 is ignited.

Generally, the maximum range that can be reached by gun fires is about 1500 m for a pistol and about 2500 m for a rifle. However, the effective range of bullets, that is, the maximum distance that a shooter can aim at a target of 50%, is about 50m for a pistol and about 600m for a rifle.

Therefore, the triggered bullet is meaningful only within the valid range, and it is very likely that the bullet will not be able to meet the target if it exceeds the effective range. If the triggered bullet fails to hit the target, it will strike a person or facility behind the target, resulting in unintended loss of life and property. Therefore, if the warhead fired from the gun gun is out of the effective range, bullets are required to reduce the energy of the bullet and limit the range.

The present invention provides a bullet which can limit the range of the bullet so that the bullet that does not meet the target can prevent an accident that damages human or property behind the target.

According to a preferred embodiment of the present invention, a cartridge triggered by a firing pin of a gun includes a cartridge having a propellant therein, case); A rim disposed at the bottom of the shell and struck by the ball; A priming primer extending from the rim to the charge and igniting the charge for the charge by the impact of the ball on the rim; And a through hole is formed in the hollow inside, and a reciprocating charge for reverse rotation is disposed inside the hollow, and a through hole is formed through the hollow to the tip opposite to the rim And includes a detonator including a detonating primer extending from the inner side of the shell to the hollow interior of the bull's eye. The reciprocating charge is ignited at a time difference by a detonator primer, and the bullet emitted from the shell discharges into the through hole The range of the range is limited by the explosive force of the charge for the reversal.

Basically, the range of the tanzai is most influenced by the explosive power of the trigger charge placed inside the shell. Therefore, it is possible to control the amount of the explosive charge or adjust the amount of the explosive charge of the explosive charge. However, in any case, it is irrelevant to the control of the range after the Tanzanite is triggered.

On the other hand, in the bullet of the present invention, the range of the bullet which has already been triggered can be adjusted as designed.

Specifically, the explosion time of the reversal charge is controlled to control the range of the already triggered tanzai. For example, by adjusting the length of the primer tip, you can control the time it takes to ignite the backbone charge, and by lowering or increasing the flammability of the primer tip, you can control the time it takes for the primer tip to ignite the reversible primer. .

That is, the reciprocating charge is ignited at a time difference by at least any one of the length, type, and difference in flammability of the detonating primer. When the charge for the reciprocating is ignited, the explosive force is discharged to the through hole. And the range is limited. Therefore, the inner diameter of the through-hole allows the explosive force of the dragged charge to be discharged to the through hole opposed to the trigger direction of the bullet. Here, the category may include the difference in the components used in the charge.

Further, a plurality of through holes may be provided, and the through holes may be provided in an oprilistic shape in which the inner diameter gradually decreases toward the tip of the bullet from the hollow inside of the shell.

As a reference, it is possible to control the range by controlling the composition and amount of the charge for the backbone, as well as the charge for the trigger.

According to another preferred embodiment of the present invention, there is provided a method of manufacturing an electric discharge lamp, comprising: a shell having a shell for placing a charge agent therein, a frame disposed at a lower portion of the shell and being struck by the shell, A detonating primer for igniting a charging charge and a bullet of a bullet which is coupled to the upper portion of the casing and includes a bullet fired from the casing by ignition of the charging charge. The bullet has a hollow body having a through hole formed through the hollow to the front end opposite to the rim; A reciprocating agent disposed in the hollow interior; And a reciprocating primer extending from the interior of the hollow of the tanzai to the inside of the shell. The reciprocating charge is ignited at a time difference by the primer for the reciprocating star. The explosive force of the reciprocating charge discharged from the shell to the through- Is limited.

The bullet according to the present invention can arrange the bullet charge in the inside of the bullet and restrict the range of the bullet emitted from the bullet by forming a through hole in the bullet for discharging the explosive force of the bullet for the inverted bullet opposite to the bullet direction of the bullet have.

In addition, by adjusting the time that detonator charges explode with a detonator primer, it is possible to limit the range of the tanzan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

FIG. 3 is a cross-sectional view of the bullet, FIG. 4 is a perspective view of the bullet, and FIG. 5 is a cross-sectional view of the bullet.

1 to 5, the bullet 100 includes a shell 110, a rim 120, a trigger primer 130, and a bullet 150.

The bullet 100 is triggered while the rim 120 is struck. In the inside of the shell 110, a charging charge 140 is disposed for triggering, and the range of the charger 150 is basically dependent on the explosive force of the charging charge 140.

The rim 120 is generally disposed in the lower portion of the shell and is integrally formed with the shell, and prevents the charge 140 from being lost below the shell 110.

The trigger 130 is disposed at the center of the rim 120 and is fired by a blow of the ball. The trigger 130 is provided with a shell 110, in which the charge 140 is disposed, So that the charge agent 140 can be ignited. When the trigger charge 140 is ignited, the shell 110 is discharged from the chamber of the gun, and the bullet 150 is blown in the trigger direction.

The tanzas 150 are generally fitted to the upper portion of the shell 110, and in this embodiment also, the tanzas 150 are joined to the upper portion of the shell 110.

Meanwhile, the bullet 150 of the present embodiment is made hollow with its interior being hollow, and the reversible charging reservoir 154 is disposed in the hollow interior 152. A through hole 158 is formed through the hollow interior 152 and the tips of the bulge 150. It also includes a detonating primer 156 extending from the inside of the shell 110 to the hollow interior 152 of the bullet 150.

Therefore, the turbo charger 150 that has already been triggered ignites the priming primer 156 at almost the same time as the priming charge 140 is ignited, and the primer primer 156 is charged in the reversible primer 150 154 may be ignited.

When the reciprocating charge 154 is ignited, the explosive force is discharged through the through hole 158 in a direction opposite to the triggering direction of the bull's-eye 150, so that the bullet 150 receives the opposite force and loses propulsion during flight.

At this time, the reversal charge reservoir 154 is ignited with a time difference by the primer for revolutions 156, and the time difference may correspond to the time when the primer detonator 156 is burned to the hollow inside the bull's-eye 150.

Therefore, it is possible to control the distance of the bullet 150 that has already been triggered by controlling the time taken for the ignition charge 154 to ignite, and more specifically, to adjust the length of the detonator primer to increase the time required to ignite the reciprocating charge And altering the type of primer tip, such as changing the composition of the primer tip to lower or raise flammability, to control the time it takes the primer tip to ignite the reversible primer.

In other words, the basic range of the bull's-eye 150 is determined by the charge charge 140, and it is possible to control or adjust the amount of the charge charge 140 to control the explosive force of the charge charge 140. In any case, 150) is not triggered after the trigger has been triggered. On the other hand, in the bullet 100 of the present invention, the range of the bullet 150 already in the triggered state can be adjusted as designed.

On the other hand, when the reversing drug charge 154 is ignited, the explosive force is discharged to the through hole 158, and the bullet is subjected to a force in the opposite direction of the shooting direction, and the range is limited.

In the present embodiment, one through-hole 158 is provided at the center of the bulge parallel to the triggering direction. However, within the range capable of discharging the explosive force of the reversing charge charge 154 in the triggering direction of the bullet, .

5, the through hole 158 is provided in an oprisy shape in which the inner diameter gradually decreases from the hollow portion 152 of the shell 110 toward the tip of the bullet 150. As shown in FIG. .

Although the present invention has been described with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that
