Environmental protection and safety firecrackers

Abstract

An environmentally friendly and safe firecracker, comprising a shell and a lead wire, the shell is a U-shaped plastic molded part with an open end and a closed end, the inner cavity of the closed end is provided with a gunpowder part, and it is characterized in that: the shell It is a thin-walled shell, and also includes an end cover, the end cover is a plastic molded part, and the end cover is provided with lead through holes. One improvement is that the end cap is provided with a downwardly extending limiting foot. The invention has a simple structure, the shell and the end cover can be molded at one time, which is convenient for industrial production, has high safety factor in the production process, low cost of raw materials and processing, and the overall cost is reduced by more than 30%; the shell is closed, the moisture resistance is good, and the product reliability is high; Crisp, with echo effect, good burst loudness; burst rate of more than 95%, good safety performance; no paper scraps in discharge, discharge waste can be recycled, and the environmental protection benefits are remarkable.

Description

technical field [0001] The invention relates to a firecracker structure. Background technique [0002] Traditional firecrackers are mostly made by hand or with auxiliary machinery. They are made of paper rolled into a casing, filled with gunpowder, sealed at both ends with soil, and lead out from one end. String-shaped firecrackers are made of multiple firecrackers. Its production process is complicated, including multiple processes such as paper cutting, reeling, soil crushing, back sealing, drying, charging, upper leads, and weaving. There is a danger of explosion during its production and transportation. The paper shell is not moisture-proof, the processing efficiency is low, and the product quality is unstable. It not only wastes paper, pollutes the environment, but also easily causes fire. The Chinese patent No. 99230172.6 discloses a plastic tube type firecracker structure, the housing adopts a U-shaped molded part with an open end, and the open end is provided with a...

Problems solved by technology

Its production process is complex, including multiple processes such as paper cutting, reeling, soil crushing, back cover, drying, charging, upper leads, and weaving.

There is a risk of explosion during its production and transportation. The paper shell is not moisture-proof, the processing efficiency is low, and the product quality is unstable. It not only wastes paper, pollutes the environment, but also easily causes fires.

The Chinese patent No. 99230172.6 discloses a plastic tube type firecracker structure, the housing adopts a U-shaped molded part with an open end, and the open end is provided with a bayonet fixing lead wire. This structure simplifies the process, but because its housing is thick The wall-shaped shell, after being fired, the shell still maintains the original single shape. When the gunpowder detonates, the gas is ejected from the opening end, and the shell is ejected in the opposite direction. It is easy to hurt people and has poor safety, so it has not been widely used.
