Embodiment Construction

[0016] Referring to the accompanying drawings, reflecting a specific structure of the present invention, the special-shaped composite fireworks with double aerial modeling includes a single tube 1 filled with propellants and effect drugs. The right cylinder row is combined; each straight cylinder row is composed of a number of vertical single cylinders 1 glued side by side in a row, and each left cylinder row is composed of a number of leftward inclined single cylinders 1 glued in a row. Each right-hand cylinder row is composed of a number of right-inclining single cylinders 1 glued side by side; A combination of rows sandwiched in between constitutes the W-shaped combination.

[0017] In this example, the combined fireworks include a straight-up group A101 located in the front and a straight-up group B107 located in the rear. It consists of rows of straight cylinders that are adjacent to each other in the direction.

[0018] A W-shaped group is arranged between the straight...

Abstract

The invention discloses a dual-sky-model combined type special-shaped combined firework. The special-shaped combined firework is formed by combining a plurality of straight-upward cylinder rows, leftward cylinder rows and rightward cylinder rows; the straight-upward cylinder rows are sandwiched between the leftward cylinder rows and the rightward cylinder rows in the front-back direction divide soas to form a W-shaped combination; propellant powder of single cylinders of each cylinder row is connected in series through fire-transmitting leads, and the fire-transmitting leads among the cylinder rows are connected in series on the side surfaces of the cylinder rows through fire-passing leads; the fire-transmitting leads are connected to the fire-passing lead through connecting mechanisms; and each connecting mechanism comprises a fire-transmitting lead taper sleeve, a fire-passing lead sleeve and a time-delay quantitative inserting sheet. The special-shaped combined firework has teh advantages that the combined presentation of the sky effects of the straight-upward model and the W-shaped model can be realized, and the performance means of the combined firework can be innovated; andmeanwhile, a large amount of ignition harness joints of the large-scale combined firework can be connected conveniently, rapidly, efficiently, reliably and accurately through the connecting mechanisms, and therefore accurate control of the firework display rhythm can be guaranteed.

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 filled with propellant and effect drug (also called effect piece), and the single tube generally refers to a rolled paper bobbin. In the prior art, the aerial modeling scheme of combined fireworks display is monotonously repeated, and innovation mostly lies in the different collocations of colors and effects, which is difficult to meet the market demand of constantly improving taste. Contents of the invention [0003] In order to solve the above disadvantages, the technical problem to be solved by t...
