Firework structure

Abstract

The invention discloses a firework structure comprising an outer box in which ten rows of firework setoff barrels are arranged. A firework main ignition lead is arranged outside the outer box. Each firework setoff barrel consists of an outer barrel and an inner barrel arranged inside the outer barrel. The bottom of the outer barrels is provided with bottom mud, a black powder layer is arranged on the bottom mud, one end of the black powder layer is connected to and arranged at a setoff barrel ignition lead, and the other end is provided with a fire transfer lead. A perforated paper board is arranged on the black powder layer. The inner barrels are arranged on the perforated paper board. A tail powder layer is arranged at the bottom of the inner barrels and above the perforated paper board. A mud isolation layer is arranged on the tail powder layer. Exploding powder is arranged inside the inner barrels and above the mud isolation layer. Multiple bright beads are uniformly arranged in the exploding powder. A fire passing lead is vertically arranged inside each inner barrel, and the fire passing lead is connected with the exploding powder and the black powder layer. The firework structure has the advantages of safe setoff and reasonable arrangement.

Description

Technical field [0001] The invention relates to the field of fireworks, in particular to a firework structure. Background technique [0002] Although there are reports of personal injuries caused by the setting off of fireworks and firecrackers during the Spring Festival every year, a cultural act that has lasted for thousands of years is forcibly banned, and it is inevitable that some people will choke on food. The left hand is the tradition and the right hand is the reality. The ultimate goal in front of government policy makers and industry experts is to allow consumers to set off a safe "cannon". At present, for molded products with an inner diameter of 28 and a height of 175, the shape of the launch tube on the bottom of the launch tube on the main body is a circular flat bottom with a diameter of 26.5mm, and the amount of military spray is 2.2 grams per shot. In the prior art, when the bottom of the launch tube is inserted and lifted, and the bottom gasket is installed aft...

Problems solved by technology

For example, when the charge worker was talking to the person next to him during the charging process, he suddenly forgot that he had already filled the current outer barrel with propellant, so he installed it again, so that the barrel was filled with double the amount of military nitrate. When the deflagration pressure of double military industrial nitrate cannot be exceeded, a crack will be formed, and if the crack expands further, an explosion tube may appear
