Abstract
The utility model relates to a rocket barrel firework which is composed of a top shell, a barrel body, a launching barrel, leading wires and leading wire sleeves. The utility model is characterized in that a spherical firework bullet is arranged in the barrel body; the external layer of the firework bullet is a spherical paper shell, the internal layer is provided with spherical exploding sounding powder, and the middle layer is provided with bright beads in various colors. As a result, a definite shape can be formed after a firework explodes and sounds in the air so that the setting-off effect is enhanced.
Description
The utility model is a kind of rocket launcher fireworks.
Existing rocket launcher fireworks are made up of top shell, cylindrical shell, launching tube, bright pearl, fuse cord, lead-in wire, lead-in wire cover, fill out in the cylindrical shell and put explosive, bright pearl of all kinds mixes with explosive fills up cylindrical shell, bright pearl to be distributed in cylindrical shell shapeless, make that explosive explodes after, bright pearl can't form the firework effect of definite shape aloft, and launching tube is paper products, and holding capacity is limited, and the bottom of launching tube is filled with bed mud, make that the emission dose that is pressed in the launching tube is few, the height of rise is low.
The purpose of this utility model is to provide the rocket launcher that a kind of firework display effect is good, range is high fireworks.
The utility model be achieved in that the rocket launcher fireworks by top shell, cylindrical shell, launching tube, lead-in wire, lead-in wire cover, form, the top valve jacket is connected on the cylindrical shell top, hydrargyrum oxydatum crudum is housed in the launching tube, launching tube is positioned at cylindrical shell, lead-in wire is socketed on the cylindrical shell bottom, it is characterized in that being equipped with in the cylindrical shell spherical display shell, the fuse cord of display shell stretches in the launching tube, and contacts with last hydrargyrum oxydatum crudum in the launching tube.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
The rocket launcher fireworks are by top shell 1, upper shell 2, lower shell 3, launching tube 4, lead-in wire 5, lead-in wire cover 6, form, cylindrical shell can be divided into upper shell 1 and lower shell 2, upper shell 2 is the paper shelly, taper top shell 1 is socketed in upper shell 2 tops, the bottom of upper shell 2 is connected with lower shell 3 sockets, launching tube 4 is positioned at the cylindrical cavity of lower shell 3, lead-in wire cover 6 is socketed on the bottom of lower shell 3, the outside of lower shell 3 is provided with bar shaped cavity 14, to insert vertical rod 7 in use, it is characterized in that being equipped with in the upper shell 2 spherical display shell, the skin of display shell is spherical paper shell 8, and internal layer is spherical explosive layer 9, and the intermediate layer is a bright pearl 10 of all kinds, the fuse cord 11 of display shell stretches in the launching tube 4, and contacts with last hydrargyrum oxydatum crudum 13 in the launching tube 4.For spacing, the display shell top is provided with papery baffle plate 15.
In order to make the higher of rocket launcher emission, also be filled with propellant powder 12 in the cylindrical shell cavity between launching tube 4 and display shell.
In order to solve the stressed low problem of launching tube made of paper, make hydrargyrum oxydatum crudum 13 more solid in launching tube, to set off effectively, launching tube 4 of the present utility model is a metal cylinder, and the bottom of metal cylinder has fairlead, and lead-in wire 5 stretches out from the fairlead of metal cylinder.
In order both to save material, make launching tube can hold certain pressure again, the wall thickness of metal cylinder is 0.6～2mm, the best is 0.8～1.1mm.Be weight reduction, metal cylinder is an aluminum barrel.
The utility model is owing to be provided with display shell in cylindrical shell, firework bright bead can aloft be shaped, and has strengthened firework display effect, and launching tube is a metal cylinder, and the dose in the tube is increased, and the medicine-feeding layer is solid, and the rocket lifting height increases.
