BOOSTE PIPE STRUCTURE OF HAND GRENADE}

The present invention relates to a training grenade, and more specifically, to the structure of the detonator pipe to prevent the occurrence of safety accidents while maximizing the training efficiency by changing the structure of the detonator pipe storing the detonation gunpowder in the fuse body. It is about.

In general, a grenade is a small bomb for melee combat for killing or destroying an enemy or weapon in close combat with an enemy, and is made relatively light so that a person can pick it up and throw it by hand.

The grenade is composed of a grenade body containing explosives and a fuse body for igniting the explosives charged in the main body, and the fuse body is composed of a safety ring, a safety creep, and a safety handle.

On the other hand, when the training is not the actual combat situation, the explosive force is relatively small, and trained using a training grenade that is manufactured separately so that there is no danger of death, and such a conventional training grenade has a retarder in the fuse body having a working primer. It is built in, and the lower part is equipped with a detonator tube for storing the explosive gunpowder.

However, in the related art, only the squeeze effect caused by the ignition of the squeak explosive appears when training with a grenade for practice, so that the trainees need a visual effect for a more practical effect.

In addition, in the case of an unexplosive grenade that is not ignited to the detonator tube, there is a problem that a safety accident occurs due to the explosion of explosive gun powder instantaneously in the state of being left on the ground because the collection process or the collection is not made.

The present invention is proposed to improve the above problems in the prior art, to maximize the training efficiency by allowing the trained soldiers to exhibit the auditory and simultaneous visual effects by using a hand grenade for military training In addition, it aims to increase the safety of use by eliminating the risk factors of grenade grenade.

The above object is provided with a detonation gunpowder storage space in which the detonation gunpowder is built in the upper part and a smoke agent storage space in which the smoke agent is embedded is provided in the lower part; A barrier layer having a multi-layer structure for partitioning the explosive charge storage space and the smoke storage space; The side wall of the detonator can be achieved through the detonator tube structure of the training grenade, characterized in that the through-hole discharge port is formed.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the overall configuration of the grenade for practice according to the present embodiment, as shown in Figures 1 and 2 fuse body 100 has a safety ring 111 and a safety creep 112 and the safety handle 113 is The upper housing 110 is composed of, the primer 121 and the primer holder 122 is composed of a lower cartridge 120 is loaded with a retardant (c) is contained therein, mutually corresponding parts Screw grooves 114 and 124 are formed in the cartridge to form a cartridge structure that can be assembled and disassembled with each other.

In addition, screw grooves 115 and 205 are also formed in the grenade body 200 and the upper housing 110 corresponding thereto so that the assembly body of the fuse body 100 can be assembled. The grenade body 200 is ground when throwing. It is preferable to use a mixture of minerals such as soil having a weak strength so that it can be easily broken even when the impact force falls.

On the other hand, the lower cartridge 120, the detonation tube 130, which is the core technology of the present invention is press-fitted to the lower end portion, the detonation explosive charge storage space (131) and the detonation gunpowder (a) is built in the detonation tube 130; , And a smoke screen storage space 132 in which a smoke screen agent (b) is built is provided at an upper and a lower sides thereof, and has a multilayer structure for partitioning the explosion-explosive storage space 131 and the smoke storage space 132. 133 is provided in the middle, and the through-hole discharge port 134 is formed in two places which are mutually symmetrical in the interruption side wall of the detonation tube 130. As shown in FIG.

In particular, the blocking film 133 is sequentially formed of a polyethylene (polyethylene) plate 133a, a steel mesh (133b), and a polyurethane (polyurethane) plate (133c) from the top layer. The lowermost layer, which is provided in a stack and contacts the smoke storage space 132, is provided with a conductive plate 133d formed by coating the black powder in a thin film on the paper to facilitate complexation.

In the PE plate 133a and the PU plate 133c, a minute through hole (h) having a diameter of about 1 mm is formed at the center to allow a small amount of heat and pressure to pass therethrough, so that heat transfer to the conductive plate 133d can be achieved. It was.

In addition, the blocking paper 135 to prevent the external exposure of the discharge port 134 is attached in a form surrounding the outer periphery of the detonator tube 130, the blocking paper 135 is not contained ash, such as ash. PVC coated on one surface of the porous filter paper 135b, which is not porous, to form the resin coating layer 135a, and when the blocking paper 135 is attached, the filter paper 135b is positioned inside the contacting detonator tube 130 and the resin coating layer ( 135a) is located outside.

In the figure, reference numeral 136 denotes a branch stopper blocking the lower portion of the detonator tube 130.

The working effect of the detonator tube of the present invention according to the use of the grenade constituting such a configuration will be described.

Training grenade according to an embodiment of the present invention has a conventional blow-type fuse structure in which the sinking not shown when throwing strikes the primer 121, the explosive pressure is generated in the blown primer 121 In addition, the retarding powder (c) is ignited to generate a combustion flame.

Then, the combustion flame generated from the delayed explosive powder (c) is gradually transferred to the lower part, and accordingly, the explosion and pressure are generated by igniting the explosive powder (a) charged in the detonation pipe 130.

At this time, if the blast pressure generated in the direction of the lower smoke screen agent, the smoke stopper (136) can be released while the stopper stopper (136) of the lower end of the stopper stopper 136, in the structure of the present invention, the detonation pipe 130 Since a plurality of discharge holes 134 are formed on the side wall of the side wall), most of the blast pressure is released to the outside of the detonation pipe 130 after separating the blocking paper 135 blocking the discharge hole 134 and the minimum pressure. Only (1.2kg / ㎠) will be delivered to the lower side.

Then, a small amount of heat and pressure transmitted due to the explosive explosion (a) ignition is dispersed in the wire mesh (133b) after passing through the central hole (h) of the PE plate 133a forming the uppermost layer of the barrier film 133, and then As it passes through the central through hole h of the PU plate 133c and is transferred to the conductive plate 4, it is ignited by the softening agent (b) that is in close contact with the lower portion, thereby generating a soft film.

Therefore, it can be seen that the operation of the detonator tube 130 according to the present invention can exhibit the auditory effect due to the binge action caused by the explosion of the explosives and at the same time visual effects due to the release of the smoke agent can be maximized the training efficiency. have.

On the other hand, the misfire may occur due to the abnormality of the internal parts during the throwing drill, in this case, due to the deformation force of the blocking paper 135 surrounding the detonator tube 130, dropping from the detonator tube 130 occurs, the ejection opening 134 is naturally open, and accordingly external discharge of the drunk a is stored therein.

That is, the moment the grenades contact the ground, the grenade body 200 is broken and the detonation tube 130 is exposed to touch the ground, the blocking paper 135 blocking the discharge port 134 is a filter paper that absorbs water well ( When the moisture absorbs moisture such as dew from the ground due to the characteristics of the filter paper, the adhesive force between the filter paper 135b and the detonator tube 130 is weakened and is separated. At this time, due to the difference in the expansion coefficient, the bending to the outer resin coating layer 135a side is caused. As a result, the blocking paper 135 is deformed to open the discharge hole 134, so that the detonating agent (a) inside the detonation pipe 130 naturally leaks to the outside or contains a large amount of water, thereby exploding its original function. It will lose the function of binge drinking.

Therefore, even after the grenade is thrown out, it is obscured by features such as grass and forests, and even if it cannot be collected, after a certain period of time, the external release of the detonating agent stored in the detonator proceeds to prevent any further explosive power. It shows the advantage of preventing accidents.

As described above, the detonator tube structure of the present invention enables the trained soldiers to use the grenade for exercise to show the auditory effect of the explosion and the visual effect of the smoke release. By creating a similar atmosphere, it is possible to maximize the training efficiency, and together with this, it is possible to increase the safety of use and handling by preventing the occurrence of a dangerous situation in case of an unexplained grenades.
