Problems solved by technology

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, etc.
[0003] In the prior art, fireworks with subtitle patterns belong to shelf fireworks, that is, a high platform is set up on the ground to hang and set off, as disclosed in patents such as the "firework effect tube with sideways fire spraying" disclosed in CN2718504 and the "combined structure of fireworks with subtitle patterns" disclosed in CN2903902. Content, although it can accurately and completely reflect complex patterns or Chinese subtitles, etc., it cannot be released in the air

Embodiment 1

[0013] Embodiment 1: see figure 1 , reflecting a specific structure of the present invention, the firework shell effect piece showing the subtitle pattern in the sky includes a rectangular fireproof cloth 101, and the two corners of the upper edge of the shorter side are respectively connected to the central vertical line 103 of two parachutes 102. In the state of unfolding in the air, the length of the fireproof cloth in the horizontal direction is smaller than the length in the vertical direction, which can prevent the fireproof cloth, especially the phenomenon that the lower part of the fireproof cloth is rolled sideways. Therefore select the shorter side of the rectangular fireproof cloth to connect the parachute.

[0014] Preferably, the fireproof cloth 101 is made of glass fiber cloth, which is relatively smooth and easy to open while being fireproof. Preferably, the central vertical line 103 of the parachute 102 is formed by a fireproof line. Such as cotton yarn, asbe...

Embodiment 2

[0018] Example 2: see image 3 , reflecting a specific structure of the present invention, the difference from Embodiment 1 is that the fireproof cloth 200 is provided with subtitle pattern fireworks on both sides, and the subtitle pattern fireworks are composed of fireworks effect tubes 201 . All the other are identical with embodiment 1.

Abstract

The invention discloses an aerial shell part for displaying caption patterns in the sky, which comprises a quadrilateral flameproof fabric, the two corners of the upper edge of the flameproof fabric are respectively connected with the central vertical lines of two parachutes, the four corners of the flameproof fabric are respectively provided with a pouring weight, and one or two surfaces of the flameproof fabric are provided with caption pattern fireworks assembled by pyrotechnic powder strips. Leads of the caption pattern fireworks are lighted, then the parachutes are opened in the sky, and the flameproof fabric hung below the parachutes is unfolded under the joint action of the pouring weights at the four corners of the flameproof fabric and the parachutes, and then the caption pattern fireworks distributed on the flameproof fabric are displayed in the sky; the formed caption pattern firework effect in the sky not only can accurately and integrally reflect complicated pattern or Chinese character captions, and the effect display time is long and can be adjusted in 6-60 seconds at will. The aerial shell part disclosed by the invention is simple in process equipment and low in setting-off cost.

Description

technical field [0001] The invention relates to a display shell effect piece. Especially the effect piece showing the over-the-air subtitle pattern. 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. The usual research direction 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 projectiles are launched into the air on the same plane and explode 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] In the prior art, fireworks with subtitle patterns belong to shelf fireworks, that is, a high platform is set up on the ground to hang and ...
