Fireworks group basin split plastic outer cylinder

Abstract

The invention discloses a split type plastic outer barrel of a firework assembly pot. The split type plastic outer barrel comprises a plurality of outer barrels and a plurality of bases, wherein an inner clamping slot is formed in the lower end of the inner wall of each outer barrel; an outer clamping slot is formed in the upper end of the outer wall of each base; each outer barrel is arranged on the corresponding base through each inner clamping slot and each outer clamping slot which are matched; two inverted-U-shaped leader slots which are staggered by an included angle of 30-90 degrees are further formed in the lower end of each outer barrel; two U-shaped leader slots which are matched with the two inverted-U-shaped leader slots are also formed in the upper end of each base; the inverted-U-shaped leader slots and the corresponding U-shaped leader slots form leader holes; and a gunpowder sunken part is further arranged on the upper part of each base. The split type plastic outer barrel is simpler and more convenient in penetrating and leading operation, and does not need punching, so that the processing processes are simplified, and the materials are saved; and adjacent leaders are effectively prevented from a fire mixing phenomenon, thereby improving the quality of the assembly pot fireworks.

Description

technical field [0001] The invention relates to the technical field of combined fireworks production, in particular to a split-type plastic outer cylinder of fireworks group pots. Background technique [0002] Due to the advantages of low cost, good strength, low moisture resistance, reusability, and high safety, the plastic outer cylinder of fireworks is gradually replacing the traditional paper outer cylinder of fireworks. When the plastic outer cylinder is inserting the lead wires, holes are first punched on both sides of the lead table of the plastic outer cylinder, and then manually penetrate from one through hole and pass out from the other through hole. Since the lead table of each plastic outer cylinder cannot be completely in a straight line, manual insertion is difficult, slow, and the insertion effect is poor; The distance of the deviation of the through holes is small, which will cause the phenomenon of crossfire between adjacent outer cylinders, which seriously...
