Multi-pattern combined type micro-smoke dynamic shelf firework

Abstract

The invention discloses a multi-pattern combined type micro-smoke dynamic shelf firework. The multi-pattern combined type micro-smoke dynamic shelf firework is characterized by further comprising a plurality of rotating mechanism assemblies, N rotating rods, firework effect components and jetting rotating devices, wherein the rotating mechanism assemblies are connected to the upper end and the lower end of a support and connected to N supporting rods respectively, the N rotating rods are connected between every two rotating mechanism assemblies, the firework effect components are connected with the N rotating rods, and the jetting rotating devices are symmetrically arranged at the two inner corners of the effect components. By the technical scheme, the rotating mechanism assemblies are driven to automatically rotate through the thrust of combustion jetting of a firework setting-off body during setting off, the newly-designed shelf firework can be provided with the multiple layers of firework effect components, the shape of the shelf firework can be changed in multiple modes, the effect component combined structure can be of a single-layer structure or a double-layer support combined structure, the shelf firework of the double-layer support combined structure can enable audiences to enjoy the firework in multiple directions on the front face and the rear face, and the audiences are not limited by the sight line or the geographic position any more.

Description

technical field [0001] The invention relates to a multi-pattern combined micro-smoke dynamic shelf fireworks, which belongs to the field of fireworks. Background technique [0002] After continuous development and changes, the shelf fireworks have developed from the most primitive electro-optical flower pattern to today's color pattern composed of colored smokeless or micro-smoke flame tubes, from smoky aluminum light waterfalls to titanium flower smokeless waterfalls, Special forms such as steamer wheels, flower trees, and Labo configurations have been derived. Every party is an indispensable main form of discharge, and the development momentum is very good. [0003] In the prior art, shelf fireworks are generally fixed on the display support, or a turntable is provided on the beam of the fixed support, or a rotating device is provided on the support. Multi-layer dynamic vision, such as the invention patent of "A Dynamic Firework Setting Apparatus in Blooming Shape" disclo...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. The motor is used as the power to stretch and drive the screw to rotate, and the structure is relatively complicated; 2. The cost of erecting the frame is high, the time is long, and it is inconvenient to install and disassemble

Another example is "A Five-Color Cross Rotating Colored Ring Firework" disclosed in the patent literature of the State Intellectual Property Office. Its patent publication number is: CN200996813Y. Uniformly distributed support rods are arranged between the devices; the bearing device and the supporting shaft are set, and the effect body is five intersecting metal rings with fireworks tubes, which are fixed on the shelf through the bearing device and the supporting shaft set to form an interlocking sleeve. The disadvantages of the structure are: 1. The rotating metal ring is fixed on the bearing device, and the direction of rotation is limited; 2. The fireworks drug tube on the metal ring is connected with the fireworks drug tube by wires, so it is not safe to set off; 3. The pattern Monotonous, difficult to disassemble after fixed connection, restricted by the site, inconvenient to transport
