Four-layer composite effect dynamic circulation combination firework

Abstract

The invention discloses a four-layer composite effect dynamic circulation combination firework which comprises first single drums and second single drums, wherein the first single drums and the second single drums are consistent in inner diameter and height specification. The plurality of first single drums and the same number of second single drums are parallelly combined in a mode of one-by-one arrangement at intervals to form drum rows, and the adjacent first single drums and second single drums are connected through leads. A plurality of drum rows are laterally oppositely arranged to form a sector structure, the sector structure refers to the facts that the bottom of each drum row draws close, the tops of the drum rows are separated, and the drum rows are in series connection through the leads according to the setting-off sequence; joint effects of various means such as corresponding design of lead adjustment, drum bodies and a combination structure thereof and medicament dose matching and the like are combined, ever-changing dynamic pictures always maintain effect presentation of four layers in the whole firework setting-off process, the layers are clear in border and are combined harmoniously, and the pictures have high art sense of beauty.

Description

technical field [0001] The invention relates to a combined firework. Background technique [0002] According to the definitions of the national standards of the People's Republic of China GB10631-2004 "Safety and Quality of Fireworks and Firecrackers" and GB19593-2004 "Combined Fireworks of Fireworks and Firecrackers" and other normative documents, combined fireworks are fireworks products composed of multiple single tubes. A single barrel is called a shot. The single tube is the paper bobbin tube filled with propellant and effect parts. In the prior art, since each single tube can only stack three layers of different effect drugs at most, the combined fireworks can only display three levels of different effects in the air at the same time, resulting in monotonous means of expression and restricting the combination of fireworks. The innovation of the effect. The Chinese utility model patent document with the authorized announcement number 203605822U discloses "a combined ...

[0003] However, the display of different effects of the above four levels is only limited to a certain period of time, that is to say, in the whole process of setting off fireworks, only a specific aerial picture is the effect display of the four levels, and the display of the four levels of effects in other periods. There are still three layers in the aerial picture; moreover, in the aerial picture formed by the discharge, the boundaries between the various levels are not clear enough, and the picture is rather messy; making the effect of the aerial picture difficult to meet the requirements
