Fireproof and explosion-proof combined fireworks

Abstract

The invention discloses fireproof and explosion-proof combined fireworks which comprise a transmitting seat body (1), transmitting holes (2) of the transmitting seat body (1) and a fireproof cover plate (11). The transmitting seat (1) is made of light fireproof materials, a lead wire (3) is embedded in the transmitting seat body (1), the bottoms of the transmitting holes (2) are communicated with one another by the lead wire (3), inner barrels (8) are arranged in the transmitting holes (2), a lead hiding hole (4) is formed in the transmitting seat body (1), an ignition portion of the lead wire (3) is hidden in the lead hiding hole (4), the fireproof cover plate (11) is made of light fireproof materials, fireproof plugs (6) for the transmitting holes and a fireproof plug (5) for the lead hiding hole are formed in the fireproof cover plate (11), the fireproof cover plate (11) covers the transmitting seat body (1), the fireproof plugs (6) for the transmitting holes are inserted into the transmitting holes (2), and the fireproof plug (5) for the lead hiding hole is inserted into the lead hiding hole (4). The fireproof and explosion-proof combined fireworks have the advantages that the fireproof and explosion-proof combined fireworks are high in transmission precision and low in transmission powder usage, the transmitting holes are short, the manufacturing cost can be saved, the safety coefficient can be increased, the fireworks can be prevented from being ignited by external fire sources, and accordingly sympathetic detonation accidents can be completely eradicated during production, transportation and storage.

Description

technical field [0001] The invention relates to a firework, in particular to a fireproof and explosion-proof combined firework. Background technique [0002] Fireworks have a long history in our country and are deeply loved by people for their brilliance. At present, there is a kind of firework, its structure is that an inner tube is housed in the launching tube, the upper end of the inner tube is covered with an upper cardboard, the lower end is placed with a lower cardboard, propellant is housed between the lower cardboard and the bottom of the launching tube, and the lower cardboard is provided with The through hole is convenient for igniting the lead wire of the inner cylinder when the propellant is burning. When the propellant is burning, the inner cylinder is launched into the air, and the inner cylinder explodes and burns in the air to produce brilliant and colorful colors. The function of the upper cardboard and the lower cardboard is to cover the gap between the la...

AI Technical Summary

Problems solved by technology

But its disadvantage is that the manufacturing process is complicated. The manufacturing process is to first put the propellant on the inner bottom of the launch tube, then cover the upper and lower cardboard, then put it into the inner tube, and then cover the cardboard. These are all done manually. The time is long, which affects the production efficiency of fireworks, increases the cost of fireworks manufacturing, and the lower cardboard and upper cardboard are launched into the air, affecting environmental sanitation

[0003] Because the gap between the inner barrel of traditional fireworks and the launch hole is too large, in order to achieve the launch height, it is necessary to increase the amount of propellant, resulting in a large amount of propellant. The same launch height also requires a high launch tube height, thereby increasing The bulk of the fireworks, which increases storage and shipping costs

[0004] When installing the lower cardboard and the upper cardboard in traditional fireworks, the lower cardboard and the upper cardboard will be deformed, resulting in the lower cardboard and the upper cardboard being stuck in the launch tube, which is prone to the phenomenon of tube explosion

The gap between the inner cylinder and the launch tube is large, and it is difficult to ensure the launch accuracy

[0005] The traditional launching base is made of multiple single paper launching tubes bonded together with glue. The glue fails due to moisture. When firing, the multiple launching tubes become loose and fall to the ground. meters, endangering the safety of people's life and property

[0006] The traditional launching base is made of multiple single paper launching tubes bonded together with glue. During the manual assembly process, due to manual extrusion, or the paper tube is damp, the paper tube is easily deformed, resulting in the inner tube cannot be removed from the tube. Launched out of the deformed launch tube, which will cause the tube to explode and catch fire, which is prone to safety accidents

[0007] Traditional fireworks, because the ignition head of the fuse is exposed and the material is paper fiber, are prone to combustion and explosion during production, transportation and storage. External fire and combustion will cause the fireworks to explode as a whole, and major accidents often occur. National property, people's lives are endangered

[0008] While fireworks bring people laughter, there are also huge safety hazards. There are huge safety hazards in the production, transportation and storage of fireworks. When people see fireworks, they will think of explosions and fires. It causes great psychological pressure on people, and at the same time causes great losses to people's lives and property. This is the inevitable result of traditional fireworks.
