Lead-embedded firework launching base

Abstract

The invention discloses a lead-embedded firework launching base which comprises a launching base body (1) made of light materials and launching holes (2) of the launching base body (1). Leads (3) are embedded in the launching base body (1), the bottoms of the launching holes (2) are communicated through the leads (3), different connection modes are adopted by the leads (3) in the launching base body (1) according to different rules of firework launching, and the inner space of each launching hole (2) is an inverted cone with a small bottom and a large top. The lead-embedded firework launching base improves launching accuracy, reduces propellant dosage, lowers the height of the launching holes, saves manufacturing cost, improves a safety system, is rapid in setting-off rhythm, high in production efficiency, free of blaze phenomenon, environmentally friendly and various in launching form and saves energy.

Description

technical field [0001] The invention relates to a firework launcher, in particular to a lead wire pre-embedded fireworks launcher with various launching forms. 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...

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
