Firework bomb structure with double explosion effect

Abstract

The invention discloses a firework bomb structure with a double explosion effect. The firework bomb structure comprises an outer tube integrally made of a glass fiber reinforced plastic material. An outer paper tube is sheathed in the outer tube, and an inner paper tube is sheathed in the upper end of the outer paper tube. The upper and lower ends of the outer paper tube and the inner paper tube are respectively provided with paper sheets as covers. The center of the inner paper tube is filled with explosives, and mud plugs are arranged on the upper and lower sides of the explosive. The lowerend of the outer paper tube is filled with the explosives, the mud plugs and propellant in order from top to bottom. The propellant of the outer paper tube is provided with two fuses. One fuse extendsthrough the wall of the outer paper tube, and the other fuse goes upward through the mud plugs to communicate with the explosives. The firework bomb structure uses the outer tube structure made of the glass fiber reinforced plastic to overcome the defect that danger exists in the prior art fireworks display, and combines a double layer structure of the outer paper tube and the inner paper tube inside the outer tube. The effects of the sound, light, color and fog of the double explosion of fireworks after the fireworks are lifted off. The firework bomb structure is widely used to support the production of fireworks.

Description

technical field [0001] The invention relates to the firework launch technology, in particular to a firework shell structure with double-explosion effect. Background technique [0002] my country is a big producer of fireworks and firecrackers, and the fireworks industry has become the pillar of economic development in some areas; the current structure of fireworks generally includes an outer tube and an inner tube, the inner tube is set in the outer tube, the pyrotechnic powder is filled in the inner tube, and the lead wire follows the outer tube. The inner wall of the barrel extends downwards and is plugged into the bottom of the inner tube. When the fuse is ignited, the inner tube is separated from the outer tube and flies out, and then explodes after being lifted into the air, producing light, sound, color, fog and other effects in the air, brilliant The sparkle of pink powder can enhance the lively and joyful atmosphere. [0003] The outer tube and inner tube of existing ...

AI Technical Summary

Problems solved by technology

[0003] The outer tube and inner tube of existing fireworks are generally all made of rolled paper. If the inner tube is installed in a wrong position or the propellant powder is installed in a wrong position, it is easy to cause the inner tube to explode in the outer tube without being lifted into the air, causing the mud plug and The pyrotechnic powder shoots around, so it is easy to accidentally injure the fireworks display operator, and the risk factor is relatively high; at the same time, as consumers, including the audience, have higher and higher requirements for fireworks, fireworks manufacturers must continue to innovate, including from the structure of fireworks. Innovate to meet the needs of users and audiences, to achieve the purpose of developing markets and improving competitiveness
