Embodiment 1

[0031] Embodiment 1: see figure 1 , reflecting the specific preferred structure of the bright bead positioning substrate of the present invention. The grid-shaped bright bead positioning substrate 2 is made of plastic molding. The bright bead positioning substrate 2 is composed of lines 4 forming the shape of the preset subtitle pattern "Happy", the lines 4 are set as a groove body, and the fireworks shell bright beads 3 are evenly arranged and fixed in the groove cavity. A method of gluing and covering a layer of gauze paper on the opening at the top of the cavity can be used. The width of the groove is corresponding to the diameter of the built-in fireworks shell bright beads 3, and the opening at the bottom of the groove is slightly smaller than the top opening to prevent the bright beads from falling off. Taking the center point "A" of the preset subtitle pattern shape "Xi" as the inside, the side wall of the tank body is slightly inclined outward. The positioning subst...

Embodiment 2

[0035] Example 2: see Figure 8 , the bright bead positioning substrate is also composed of groove body-shaped lines 21, the fireworks bright beads 23 are evenly arranged and fixed in the groove cavity, and a circular positioning frame 22 is provided, and the center point "B" of the preset pattern For the inside, the side walls of the tank body are slightly inclined outward. The difference is that the preset pattern is a flower shape. Embodiment 3: see Figure 9, the bright bead positioning substrate is composed of lines 31 forming the shape of the preset subtitle pattern, and the fireworks marbles 32 are evenly arranged and fixed on the lines 31 . The fixation can be in the form of adhesive fixation or gauze paper wrapping. Connecting reinforcing ribs 33 are provided between the lines 31 . In this example, no slot body and positioning frame are set, just put the bright bead face up and place it flat in the inner cavity of the shell.

Embodiment 4

[0036] Embodiment 4: see Figure 10 , the bright bead positioning substrate 44 is in the shape of a grid, and the fireworks marbles 42 are evenly distributed and fixed in the grid 43 of the bright bead positioning substrate 44 according to the preset subtitle pattern. The grid size of the bright bead positioning substrate 44 is corresponding to the size of the built-in fireworks bomb bright beads 42, the bottom opening of the grid 43 is slightly smaller than the top opening to prevent the fireworks bomb bright beads 42 from falling off, and the top opening of the grid is provided with a sealing layer Such as gauze paper adhesive cover layer. Taking the central point "X" of the preset subtitle pattern shape as the inside, the side walls of the grid 43 are slightly inclined outward. Guide the bright beads to fly in an orderly manner outside the center point. Please combine Figure 11 , the bright bead positioning substrate 44 is installed in the inner cavity of the fireworks ...

Abstract

The invention discloses a display shell with captions and patterns. An inner cavity of the display shell is provided with a positioning base plate; bright beads of the display shell are aligned uniformly according to the predetermined captions and patterns and fixed on the positioning base plate. The positioning base plate is made of a material which is easy to break under the explosive impact. Due to the arrangement of the positioning base plate, the reference location of the bright beads is exact and reliable, the flying path is orderly, and the burning bright beads can show the relatively complex patterns or sculpts of Chinese character captions in the air according to the predetermined captions and patterns.

Description

technical field [0001] The invention relates to a firework shell for displaying subtitle pattern shapes in the air. Background technique [0002] It has always been the dream of people in the fireworks industry to use fireworks to display the designed subtitle pattern effect in the sky. One is to use multiple fireworks shells to detonate at fixed points in the air at fixed times, and the combination of multiple explosive point effects forms preset subtitles or patterns. The powder pillars are launched into the air on the same plane and bloom at the same time, creating a "big footprint" pattern. Not only does it have high requirements for launch equipment, venues, materials, etc., but it also costs a lot, and it is difficult to form complex patterns or Chinese subtitles. [0003] Another method is to use a single shell to achieve it. Multiple bright beads are arranged in a preset pattern and embedded in the mixture of detonated gunpowder and filler in the inner cavity of th...
