Description

[Detailed description of the invention] The invention of the present application relates to a new pseudo-cannon smoke tube used for example in 11th practice shooting of rocket artillery, and in particular, makes shooting training more practical, and has a simple structure and is inexpensive. The aim is to provide products that can be produced in the future.

Conventional shooting training with rocket cannons, etc. is conducted by assuming that a rocket is actually fired, understanding the trajectory of the rocket, and imagining the impact that firing a rocket will have on the enemy. Or, rockets were actually fired to simulate actual combat.

However, the former, imaginary 11th training, is far from actual combat, and has the disadvantage that the training itself has little meaning; Although it is certainly significant as a target practice, it is also highly dangerous and requires a lot of money.

Therefore, in the past, attempts were made to develop a device that would make shooting training more realistic by emitting only the firing sound and smoke when operating a rocket cannon, but the weight of the rocket cannon itself changed significantly. The reality is that this has not yet been realized because it is difficult to determine trajectory and the equipment is expensive.

Therefore, the present invention provides a small, lightweight, and inexpensive rocket cannon that only emits firing sound and smoke when operated, and has a simple structure, thereby facilitating practical shooting training. The aim of the present invention is to provide a novel imitation gun smoke cylinder that can be used as an artificial cannon, and the front end side of the cylindrical shell is closed by airtightly covering the front end with a cap made of a conductive material. Appropriate buffer members were loaded on the rear end side and the explosive chamber formed between these two buffer members was filled with an appropriate smoke generator, and the inside of the smoke culvert was connected to a pair of wiring cords. The ignition bulb is buried, one end of the wiring cord is exposed outside the cap via an insulating member, and the other end is connected to the cap, details of which are shown in the accompanying drawings below. This will be explained based on specific examples.

1 shows an example of the implementation of the artificial gun smoke cylinder according to the present invention.

Reference numeral 2 denotes a cylindrical outer shell made of paper, and one end of the outer shell 2 is closed by a cap 3 made of a conductive material attached in an airtight manner.

Incidentally, this outer shell 2 may be specially manufactured for use in the present invention, but it is also possible to use a ready-made shotgun cartridge.

A fitting portion 4 recessed inward is formed approximately at the center of the cap 3, and a cord insertion hole 5 is formed in the fitting portion 4.

The front end side of the outer shell 2 thus formed, that is, the side on which the cap 3 is attached, is suitably stuffed with a buffer member 6 such as felt, and the buffer member 6 is secured to the outer shell 2 by a seat plate 7. It is pressed toward the front end.

The buffer member 6 and the seat plate 7 are provided with holes 8.9 that communicate with the cord insertion hole 5 formed in the cap 3.

On the other hand, a pressure plate 11. A packing 12 such as felt and a cover plate 13 are inserted in that order, and the edge of the ejection opening 10 of the outer shell 2 is folded inward to prevent them from coming off the outer shell 2. There is.

14 is a powder chamber formed between the seat plate 7 loaded on the front end side of the outer shell 2 and the pressure plate 11 loaded on the rear end side of the outer shell 2, and the chamber contains, for example, black powder. is filled with a smoke generator 15 mixed with a small amount of oil smoke, etc., and an ignition ball 17 connected to a pair of wiring cords 16 (g) and 16H is buried within the smoke generator 15.

Then, the wiring cord 16 (+
), 16H are passed through the holes 9 and 8.5 drilled in the seat plate 7, the buffer member 6, and the cap 3 in that order, and the positive end of the wiring cord 16 (+) is formed in the cap 3. The end of the negative cord 16 (-) is exposed through the hole 19 of the insulating member 18 formed to tightly fit into the fitting part 4 of the cap 3. 4 is formed so as to be pressed by the insulating member 18 and connected to the cap 3.

Therefore, the artificial cannon smoke cylinder according to the present invention is attached to a proper position of a rocket cannon (not shown) with the cap side facing forward, and is connected to the positive and negative sides of an ignition device (not shown) that is linked to the trigger of the rocket cannon. A positive side cord 16 (+) and a cap 3, that is, a negative side cord 16 (-) are connected to the terminals, respectively.

Then, when the rocket cannon is fired (assuming that the trigger is pulled), the ignition device is activated and current is applied to the ignition ball 17 via the positive and negative side cords 16 (+) and 16 (-). It ignites.

Then, the fire is transmitted from the ignition ball 17 to the smoke generator 15, and the smoke generator 15 burns at a pressure that expands to several tens to hundreds of times the volume of the space filled with it under normal temperature and normal pressure, and at the same time makes an ignition sound. , a pressure plate 11 loaded on the rear end side of the outer shell 2 with the pressure at that time. The gasket 12 and cover plate 13 are pushed out to open the ejection port 10 of the outer shell 2, and smoke is thereby ejected from the ejection port 10 toward the rear of the operator.

Therefore, the operator feels the tense atmosphere as if firing a rocket, except for the presence or absence of recoil, while the enemy trainer hears the firing sound (ignition sound) of the rocket (mock cannon). By checking the smoke, you can feel the tense atmosphere, and you can conduct exercises in a more realistic atmosphere.

As is clear from the above, the present invention is designed to emit the firing sound (ignition sound) and smoke at the same time as the rocket is fired (it does not actually fire the rocket). Training can be conducted more realistically.

Further, the present invention can be formed by simply packing several components into a roughly cylindrical outer shell, so the structure is very simple and can be manufactured at low cost.

Moreover, since the outer shell and most of the other components are made of relatively inexpensive paper or felt, the product price can be significantly reduced.

Furthermore, as explained in the main text, the outer shell can be made of, for example, a paper shot cartridge, so it can be made very small and lightweight, and there is no habituation that would adversely affect the weight distribution of the rocket cannon. There is also an advantage.
