Description

TRAINING GRENADE VISIBLE A FRAGMENT OF IT

The present invention relates to a training grenade, and more particularly, in order to produce the same environment as the actual grenade throwing in the grenade throwing training, a squeaking agent and a smoke agent are used. It is related to a training grenade without a conductive wire which can form a boundary layer so that an explosion does not occur even when the ignition agent and the smoke agent are incompletely filled, while the grenade throwing drill can ignite the smoke agent by the explosion of the grenade agent. .

In general, a grenade is a small bomb for melee combat in order to kill an enemy or destroy a weapon in close combat with an enemy. The grenade is made relatively light so that a person can pick it up by hand and the grenade contains a large explosive charge. It consists of a fuse for igniting the body and the explosives filled in the body.

The types of grenades are classified into subdivision grenades for personnel killing, attack grenades for weapon destruction, gas grenades for lowering enemy power, smoke grenades for signaling, and such grenades. It is necessary to learn enough usage and safety rules in advance as it can damage itself and allies by carelessness of the user.

Therefore, when training, not the actual combat situation, the explosive power is relatively small and trained with a training grenade that is manufactured separately so that there is no danger to the human body.

Training grenades are equipped with a retarder inside the fuse body with a working primer, and the lower part is equipped with a detonator that contains the explosive gunpowder.

However, in the related art, only the squeak effect according to the ignition of the squeak explosive when training using the grenade for training is required, so that the trainees need a visual effect in order to obtain a more realistic effect.

In order to solve this problem, trained grenade trainees can experience the auditory effect of the explosion and the visual effect of the smoke release, while creating a similar atmosphere to the actual combat situation. Grenades have been proposed to maximize the

As shown in Figure 1, the conventional training grenade 1, when the spring 3 in the adapter body 2 hits the ball 4 and hits the primer 5, the blown primer 5 is The smoke film was delayed for a certain time by the retardant 6, and then the smoker 7 was detonated, and the smoke film was released by the combustion of the smoke agent 8 together with the drink.

In the operation of the training grenade 1 according to the prior art, the grenade after detaching the safety pin ring and the safety clip while holding the safety handle while wrapping the body 9 with one hand when throwing the training grenade 1. When throwing (1), the ball (4) supported on the surface of the safety handle hits the primer (5) by the elastic force of the spring (3).

The primer 5 is triggered by the striking force exerted by the ball 4 leading to the ignition of the retardant 6. During this process, the detonating force of the primer 5 is transmitted to the detonating agent 7 not immediately by the detonating agent 6 but after a predetermined time, so that the detonating agent 7 explodes and the smoke agent 8 is burned. The smoke is released.

However, the conventional training grenade 1 as described above has a problem that a chemical aging reaction occurs due to the characteristics of the detonating agent 7 and the smoke agent 8 which are burned by the explosion of the primer 5.

In detail, the drunk is composed of a strong oxidizer and a metal powder, and the smokescreen is composed of a weak oxidizer and a non-metallic powder. Thus, an incomplete layer is formed at a portion where the drunk agent and the smoke agent are in contact with each other, which causes an ignition malfunction. As a result, a result of unexploded carbon was generated.

In order to solve this problem, a separate conductive wire for ignition of the smoke may be applied, but this has the disadvantage of increasing manufacturing cost and labor cost and increasing manufacturing time according to the conductive wire and the blocking film.

On the other hand, such training grenades vary widely in the training ground, and there is always a risk of loss after training due to other terrain or weeds, and if it remains unexploited and is not recovered, the body and fuse may leak out and be converted into a similar explosive. After the acquisition, if handled incorrectly, a problem occurs that causes an unexploded bomb to cause an accident.

The present invention is to solve the above problems, through the sound-absorbing agent and smoke screening agent to achieve the auditory and visual effects at the same time, while the incomplete layer is not formed between the sound-absorbing agent and the smoke screening The aim is to provide a training grenade without a fuse that allows the smoke screen to function normally.

Training grenade without a fuse according to the present invention for achieving the object as described above, the body; A fuse mounted to the body; And, there is filled with a detonating agent and smoke agent in the upper and lower parts therein and is provided in the interior of the body and includes a branch pipe cartridge which is ignited upon ignition of the fuse in conjunction with the fuse, the branch pipe cartridge of the detonating agent and smoke agent It is characterized in that it further comprises a smoke screening agent to induce the explosion of the smoke screen agent due to the explosion of the sound absorbing agent while partitioning between the sound absorbing agent and the smoke screening agent.

Preferably, the softening agent coating unit is made of a mixture of acetone solvent and nitrocellulose mixed in a gel state (a), potassium nitrate, sulfur and wood powder (b) mixed with 100% by weight.

According to the present invention, the grenade without a grenade according to the present invention can produce the same combat situation as the battle through the visual and auditory effects by using both a booze agent and a smoke agent, and the booze agent and the smoke agent are blocked without contact with each other. Thus, the ignition of the drooping agent is reliably transmitted to the combustion of the smoke screen without chemical change with time between the drooping agent and the smoke screen agent, thereby minimizing misfire.

In addition, there is an effect that can prevent in advance the safety accidents that occur when the general public learns the bomb.

As shown in FIG. 2, the training grenade without a conductive wire according to the present invention includes a grenade body 101, an adapter assembly 110, and a fuse assembly 120.

The adapter assembly 110 coupled to the grenade body 101 includes a ball 110b and a ball spring 110c, a safety ring 110d, a safety creep (not shown) and a safety handle 110e in the adapter 110a. In the assembly, the fuse assembly 120 is configured to couple with each other by a combination.

The fuse assembly 120 is configured by the fuse cartridge 121 and branch pipe cartridge 131 is coupled.

The fuse cartridge 121 is formed by crimping the primer 121b and the primer holder 121c onto the fuse 121a, and the auxiliary delay agent 121d, the retardant 121e, and the ignition agent 121f inside the fuse 121a. Is charged.

The branch pipe cartridge 131 has a lower portion of the fuse 121a in a state in which the bin 131b and the smoke 131c are filled up and down in the inner space of the branch pipe 131a having a space formed therein. As a structure that can be combined and disassembled, the fuse cartridge 121 and the fuse assembly 120 are configured.

In the branch pipe cartridge 131 of the present invention, the detonating agent 131b and the smoke agent 131c are partitioned into complete layers, for example, while preventing abnormal explosion due to the chemical reaction between the detonating agent 131b and the smoke agent 131c. The smoke screen 132 may be further included to induce an explosion of the smoke agent 131c only when the detonation agent 131b is exploded due to the throwing of the grenade 100.

The smoke agent coating part 132 may be formed of a binder (a) and a mixed powder (b) in a gel state.

The binder is a mixture of nitrocellulose and acetone solvent. Nitrocellulose is a liquid adhesive and the acetone solvent is used to dissolve nitrocellulose and bind the mixed powder.

Nitrocellulose and acetone solvents are mixed by 5 to 15% by weight, 85 to 95% by weight with respect to 100% by weight of the total binder.

This is because when the nitrocellulose is mixed at 5 wt% or less, no uniform binding is made, and when 15 wt% or more is mixed, the binding of the gunpowder is difficult and uniform binding is not performed.

This is because when the acetone solvent is mixed below 85% by weight, the viscosity of the nitrocellulose is too high, and the binding force is weak when 95% by weight or more is mixed without binding of the gunpowder.

The binder is mixed with 60 to 90% by weight relative to the total 100% by weight of the smoke screening unit 132 because the binder is too small of the gunpowder to cause misfire or excessive mixing of the gunpowder.

The mixed powder is made of 70 to 80% by weight of potassium nitrate, 12 to 18 weight% of sulfur and 8 to 12% by weight of wood powder, based on 100% by weight of the total powder. Gunpowder by potassium nitrate, sulfur, and wood powder can be easily implemented by those skilled in the art, so a detailed description thereof will be omitted.

When the mixed powder of this composition is less than 10% by weight, it is impossible to transfer the explosion of the drinking agent 131b to the combustion of the smoke agent 131c, and when it is mixed by more than 40% by weight, there is a difference in the combustion of the smoke agent 131c. Therefore, 10 to 40% by weight relative to the total 100% by weight of the smoke coating agent 132 is mixed.

If the smoke screen 132 is filled with the film 131c in the branch pipe 131a, and the thickness of the film 131c is greater than the predetermined thickness (the thickness of the drink 131b and the film 131c does not come into contact with each other). It will be possible to be formed as a layer of a specific value), and in detail, the softening agent dosing unit 132 is initially filled on the softening agent 131c inside the branch pipe 131a as a gel composition. The cured layer is formed by drying at room temperature for 1 hour to 1 hour 30 minutes. Since the cured film-curing portion 132 contains the same acetone solvent as the film-forming agent 131c, the film-forming agent 131c is chemical even when the film-forming agent 132 is in contact with the film-forming agent 131c. It does not cause a change and prevents the drinking agent 131b and the smoke agent 131c from contacting.

The action of the training grenade equipped with the fuse according to the present invention configured as described above is as follows.

When throwing the training grenade 100 according to the present invention, while holding the body 101 and the safety handle (110e) with one hand while holding the safety ring (110d) and the safety clip with the other hand after training grenade If the force applied to the safety handle (110e) is thrown when throwing (100) is the ball (110b) is the ball hit the primer (121b) in the fuse (121a) by the elastic force of the spring (110c).

When the primer 121b is ignited by the impact force applied from the ball 110b and ignited, this ignition leads to the ignition of the auxiliary delay agent 121d. During this process, the auxiliary delay agent 121d and the retarder 121e are not delivered to the detonating agent 131b of the branch cartridge 131 immediately after the explosion of the primer 121b. Therefore, the training grenade 100 ) By the throwing or throwing the training grenade 100 is not exploded in the place where the thrower can be injured, but will explode at a target location.

As a result, the insulative agent 131b and the smoke agent 131c are not normally in contact with each other by the smoke agent conductive part 132, so that an incomplete layer is not formed between the intoxicant agent 131b and the smoke agent 131b.

The explosion of the scavenging agent 131b is transmitted to the smoke screen 132, the smoke screen 132 explodes by the explosion of the scavenger 131b through the gunpowder component, and the smoke screen 132 is blasted. The smoke agent 131c is burned by the explosion.

At this time, the detonation effect by the detonating agent 131b causes the ignition agent 121f to ignite so that the ignition power is increased.

When the detonation agent 131b is delivered through the ignition guide hole 121g and the detonation agent 131b is detonated, an audible effect may be produced as if the grenade has exploded, thereby creating an atmosphere similar to an actual combat situation.

The smoke effect is that the fuse 132 is ignited by the detonation of the drink 131b, the smoke 131c is ignited by the ignition force of the fuse 132, and when the smoke 131c is burned, the smoke is discharged. In fact, the grenade explodes into a visual effect that creates an atmosphere similar to a real combat situation.

As described above, the training grenade 100 has explosion and smoke effects, and the explosive force caused by the explosion of the detonating agent 131b explodes the body 101 and the destroyed body 101 is scattered, falling to the ground, and the smoke effect. You can maximize even more.

The residue of the destroyed body 101 is used as an eco-friendly material does not have to perform a recovery operation and can be damaged in a natural state, thereby preventing environmental pollution.
