Abstract
The utility model relates to a low noise fireworks, this fireworks have a fireworks section of thick bamboo, fireworks section of thick bamboo is with a paper board closing cap after loading the propellant powder on the sealing mud, place the cardboard closing cap on the inner tube reuse on the cardboard, inner tube for the inner tube sealing mud closing cap after loading the inner tube propellant powder on the inner tube sealing mud, load on the inner tube cardboard and use the cardboard closing cap on the inner tube after the effect powder, the propellant powder even has a fuse with the inner tube propellant powder, the propellant powder even has an ignition wire. The firework explosive has the beneficial effects that after the inner barrel is shot into the air, the firework explosive is dispersed by the inner barrel propellant powder filled in the inner barrel, larger explosion sound generated by the traditional explosive is avoided, and no strong noise meets the environmental protection requirement.
Description
Technical Field
The utility model relates to a low noise fireworks.
Background
The traditional inner tube type launching fireworks are characterized in that the inner tube is launched into the air by the launching powder at the bottom of the fireworks tube, the effect powder of the fireworks is exploded and scattered by the blasting powder in the inner tube, and the effect powder is burnt in the air to give out various setting-off effects. The firework blasting powder has high explosive force and can produce great explosion sound. With the enhancement of environmental protection requirements, the noise generated by the larger explosion sound is not in accordance with the environmental protection.
Disclosure of Invention
The utility model aims to solve the problem of designing a low-noise firework which meets new environmental protection requirements.
The design scheme of the utility model is, a low noise fireworks, this fireworks have a fireworks section of thick bamboo, fireworks section of thick bamboo is with the closure clay closing end, fill on the closure clay and use the cardboard closing cap after the propellant powder, place on the cardboard and go up the cardboard closing cap with the inner tube reuse, inner tube for the inner tube closing clay closing end, use inner tube cardboard closing cap after filling the inner tube propellant powder on the inner tube closure clay, fill on the inner tube cardboard and use the cardboard closing cap on the inner tube after the effect powder, the propellant powder even has a fuse with the inner tube propellant powder, the propellant powder even has an ignition wire.
The utility model relates to a low noise fireworks's beneficial effect is, the inner tube is penetrated aerial back, and fireworks effect medicine is dispersed by the inner tube propellant powder that loads in the inner tube, does not have the tradition and adopts the great explosive sound that the explosive produced, and no strong noise more accords with the environmental protection requirement.
Drawings
Fig. 1 is a schematic structural view of a low-noise firework of the present invention.
Labeled as: 1-ignition wire, 2-firework cylinder, 3-paperboard on the inner cylinder, 4-paperboard on the inner cylinder, 5-inner cylinder, 6-effect medicine, 7-paperboard on the inner cylinder, 8-propellant on the inner cylinder, 9-sealing mud on the inner cylinder, 10-paperboard, 11-fuse, 12-propellant and 13-sealing mud.
