Fireproof and explosion-proof combined fireworks

Abstract

The invention discloses fireproof and explosion-proof combined fireworks which comprise a transmitting seat body (1), transmitting holes (2) of the transmitting seat body (1) and a fireproof cover plate (11). The transmitting seat (1) is made of light fireproof materials, a lead wire (3) is embedded in the transmitting seat body (1), the bottoms of the transmitting holes (2) are communicated with one another by the lead wire (3), inner barrels (8) are arranged in the transmitting holes (2), a lead hiding hole (4) is formed in the transmitting seat body (1), an ignition portion of the lead wire (3) is hidden in the lead hiding hole (4), the fireproof cover plate (11) is made of light fireproof materials, fireproof plugs (6) for the transmitting holes and a fireproof plug (5) for the lead hiding hole are formed in the fireproof cover plate (11), the fireproof cover plate (11) covers the transmitting seat body (1), the fireproof plugs (6) for the transmitting holes are inserted into the transmitting holes (2), and the fireproof plug (5) for the lead hiding hole is inserted into the lead hiding hole (4). The fireproof and explosion-proof combined fireworks have the advantages that the fireproof and explosion-proof combined fireworks are high in transmission precision and low in transmission powder usage, the transmitting holes are short, the manufacturing cost can be saved, the safety coefficient can be increased, the fireworks can be prevented from being ignited by external fire sources, and accordingly sympathetic detonation accidents can be completely eradicated during production, transportation and storage.

Description

technical field [0001] The invention relates to a firework, in particular to a fireproof and explosion-proof combined firework. 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 to cover the gap between the la...
