The utility model discloses an improved structure of
fireworks. Comprising a set-off effect part (1), a
deflagration part device structure (2) connected with an inner cavity in the lower portion of the set-off effect part in a sleeved mode, and an inner circle boss edge (104) located on the upper portion of the inner
cavity wall of the set-off effect part and used for positioning and placing an effect body partition plate A (105). The
deflagration part device structure further comprises an inner sleeve
straight tube body (203) and a
deflagration device threaded connection component (201) connected with the outer circle of the lower end of the inner sleeve
straight tube body, the upper opening end of the inner sleeve
straight tube body is connected with an ignition deflagration tube supporting plate (205), and the lower opening end of the inner sleeve straight tube body is of an
open structure. The setting-off effect part and the
detonation part device structure are connected into a whole through the
detonation device threaded connection component, so that the
detonation point of the ignition and detonation
pipe (206) is located in the middle of an inner cavity of the setting-off effect part for ignition and detonation. The utility model has the advantages of reasonable structural
layout, novel modeling design, good setting-off effect, safety, reliability and the like.
