Pyrotechnic launch tube structure

This creation relates to a pyrotechnic structure, and more particularly to a pyrotechnic launcher structure that can coat a gunpowder without scattering and achieve a stable launch.

According to the evolution of gunpowder in ancient China, the application of pyrotechnics has always been one of the highlights of domestic celebrations. It is common in the Spring Festival, Mid-Autumn Festival, temple fairs and other celebrations to enhance the lively atmosphere. After the fireworks are ignited, The splendour of the explosion in the moment is always able to attract people's voices, so it is widely welcomed by people, and often for the Chinese people to release at the festive banquet, and even almost every day will sound joy in a corner of Taiwan. Cannon.

Conventional pyrotechnics combines a plurality of barrels into one body. There is a firearm in the barrel. The bottom of the barrel of the pyrotechnic gun is filled with propellant powder and then filled with a red soil layer in the bottom port of the barrel. There is a small through hole for the passage of the fuse, so that the fuse can ignite the propellant gun one by one to launch the smoke gun from the barrel. Since the small through holes on the red soil layer need to be drilled one by one, and then the linear fuse line is worn, it is very time consuming, and the fuse wire does not penetrate the small through hole and is stuck in the passage of the small through hole, so that the fuse line fails. It is not ideal to ignite the propellant gunpowder. In order to solve this deficiency, the manufacturer changed the fuse to the granular gunpowder, so that one of the gunpowders filled in the small through hole could be connected with the propellant gunpowder in the barrel, and the gunpowder filled in the small through hole The other end can be connected with the fuse line outside the barrel. In order to ensure that the gunpowder filled in the small through hole can be connected with the fuse line outside the barrel and considering the factors such as rapid production and manufacturing, the fuse line outside the barrel is used. Made of granular gunpowder into a flat surface, so that The plate-shaped fuse will instantly ignite all the fireworks and lose the effectiveness of igniting the fireworks one by one. Furthermore, the plate-shaped fuse will fail to ignite all the fireworks due to cracks, broken or wet ground. not ideal.

In addition, the fireworks and guns will still be loose and swaying, and the fireworks and guns will be tilted, which will result in inconsistent and chaotic flight directions when the fireworks are fired, which not only reduces the ornamental value, but also increases the risk and even increases the risk. It can lead to accidental shots and hurt passers-by.

In addition, a firearm cannon is manufactured by filling a red soil layer and a gunpowder layer and a fuze inside the bottom end of the launching tube; and filling a hole above the gunpowder layer to prevent the gunpowder from leaking and positioning the gunpowder layer as a paper ball. As a seal (as shown in the first figure), there is also a 盖-shaped cover as a seal (as shown in the second figure), but it is easy to fall off regardless of whether the paper or 盖-type cover is a seal, and the gunpowder is scattered outside the launch tube. , thereby reducing the emission effect.

It can be seen that the above existing methods obviously have inconveniences and defects, and need to be improved. In order to solve the above problems, the relevant fields have not tried their best to find a solution, but for a long time, no suitable solution has been developed. Therefore, how to use the structure of the pyrotechnic launcher to achieve the safety of fireworks and to facilitate the stable launch is one of the current important research and development topics, and it has become an urgent target for improvement in related fields.

In view of this, the present invention is to provide a pyrotechnic launcher structure which provides a kind of firearm that can be coated with gunpowder without scattering, and achieves the stability of launch, which is its main purpose.

In order to achieve the above object, the pyrotechnic tube structure of the present invention comprises at least a plurality of gunpowder units, at least one barrel and at least one tube; wherein the barrel has a closed end and the other end is an open end, and Multiple gunpowder units are set at Inside the barrel, one end of the seat tube is closed by a filling layer, and the other end has an opening, and the barrel is sleeved in the seat tube to cover the powder medicine unit to be scattered, and the production efficiency is lowered. The cost, and the height of the opening and the closed end are between +3 mm and -3 mm, and the enthalpy reaches the stability of the fired fuel unit.

According to the above main structural features, the plurality of seat tubes are sleeved with a gun barrel of a powder medicine unit, and the plurality of seat tubes are arranged in a row.

According to the above main structural features, a buffer layer is disposed on the periphery of the plurality of seat tubes.

According to the above main structural features, the plurality of seat tubes are covered with an underlayer on the other side of the opening to be fixed.

According to the above main structural features, the buffer layer is covered with a coating layer.

According to the above main structural features, the plurality of seat tubes are attached with a film layer at the opening.

According to the above main structural features, the plurality of seat tubes are provided with partitions for arrangement.

According to the above main structural features, a lead wire is disposed between the plurality of seat tubes to connect the powder medicine unit.

The sixth picture is a schematic diagram of the combined structure of the creation.

The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples.

The first figure is a three-dimensional structure combination diagram of the creation, and the pyrotechnic tube structure of the present invention is composed of a plurality of gunpowder units 10, at least one barrel 20 and at least one tube 30; wherein the barrel 20 It is a hollow cylinder having a closed end 21 at one end and an open end 22 at the other end, and a plurality of gunpowder units 10 are placed in the barrel 20 through the open end 22, and the seat tube 30 is hollow. The tube body is provided with a filling layer 31 at one end for closing, and the other end has an opening 32, and the barrel 20 is sleeved in the seat tube 30 to cover the powder medicine unit 10, and the opening is not scattered. The height relative position of the closed end 21 is between +3 mm and -3 mm, and the enthalpy reaches the stability of the fired explosive unit 10.

Therefore, in the actual implementation, as shown in the second figure, the plurality of seat tubes 30 are sleeved with a barrel 20 having a powder medicine unit 10, and a plurality of lead wires 40 are disposed between the plurality of seat tubes 30 to connect the powder medicine unit 10. And the plurality of seat tubes 30 are arranged in a row, and the buffer layer 33 is disposed on the periphery of the plurality of seat tubes 30, and a buffer layer 34 is coated on the buffer layer 33 to make the whole seat tube 30 more stable. The plurality of seat tubes 30 are fixed on the other side with respect to the opening 32 to be fixed, and the plurality of seat tubes 30 are attached with a film layer 36 at the opening 32 to fix the barrel 20 from being shaken in the seat tube 30, thereby allowing The powder medicine unit 10 is scattered in the barrel 20.

Further, the plurality of seat tubes 30 are provided with a styrofoam forming the buffer layer 33. When the lead wire 40 is ignited, the explosive unit 10 generates an explosive force to drive the barrel 20 to slide upwardly when the seat tube 30 is slid upward, so that the seat tube 30 is easily generated. When the vibration or shaking is performed, the buffer layer 33 is used to absorb the shock, and the balance stability of the whole seat tube 30 is improved, so that the gunpowder unit 10 in each barrel 20 is continuously ignited by the lead wire 40, so that the barrels 20 can be avoided. It helps to maintain the uniform flight direction and achieve safety protection.

In addition, the plurality of seat tubes 30 are provided with partitions 37 to be arranged to bring the seat tubes 30 closer together, thereby increasing the overall stability.
