Firework setting-off device

Abstract

The invention provides a firework setting-off device. The device comprises a plurality of firework launching pipes, a launching pipe angle fixing assembly and a support. The firework launching pipes are used for internally arranging firework products. The launching pipe angle fixing assembly comprises a first plate, a second plate and a bottom plate, the first plate, the second plate and the bottom plate are parallel to one another, are obliquely arranged relative to the horizontal plane and are arranged from top to bottom in sequence. The first plate and the second plate are provided with a plurality of through holes for inserting of the of firework launching pipes. The contact ends of the inserted firework launching pipes can make contact with the bottom plate, and after the firework launching pipes are inserted in the launching pipe angle fixing assembly, a pattern formed by the free ends, not in contact with the bottom plate, of the firework launching pipes is a similar pattern with the amplified size relative to a pattern formed by the contact ends of the firework launching pipes. The device is safe in setting off, accurate in pattern, easy and convenient to use and low in cost. Especially, the device has the accurate firework setting off positioning function, and the effect obtained after setting off is kept to be highly consistent with the expected pattern.
本发明提供一种烟花燃放装置,所述装置包括多根烟花发射管、发射管角度固定组件和支架;所述烟花发射管为其内用于设置烟花产品的管;所述发射管角度固定组件包括相互平行且均相对于水平面为倾斜设置和从上至下依次设置的第一板、第二板和底板,所述第一板和第二板上均开设有多个用于插放烟花发射管的通孔,且插放后的烟花发射管的接触端能与所述底板接触,多根烟花发射管插入所述发射管角度固定组件后,其不与底板接触的自由端构成的图案相对于其接触端构成的图案为尺寸放大的相似图案。本发明提供的装置燃放安全、图形准确、装置简便、成本低廉。尤其是该装置具有烟花燃放精确定向功能,燃放后的效果与预期的图案保持高度一致性。
