Firework plastic launching basin

Abstract

The invention provides a firework plastic launching basin comprising a base, blocking pieces and a launching main body buckled on the base. The launching main body comprises a plurality of launching cylinders arranged longitudinally and transversely; a ribbed plate is arranged between the two adjacent launching cylinders on the same longitudinal row; and the blocking pieces are arranged on the launching cylinders or abut against the launching cylinders of the adjacent transverse columns correspondingly. Each ribbed plate is arranged between the corresponding two adjacent launching cylinders on the longitudinal row, the launching cylinders on the transverse columns are not connected by limited through the blocking pieces, so that the relative angles between the launching cylinders on the different longitudinal rows, and the relative positions of the opening parts of the launching cylinders on the different longitudinal rows can be changed, accordingly different patterns can be obtained after fireworks are ejected without the need of re-manufacturing of launching cylinder moulds, and thus the cost is relatively low; and meanwhile, bottom plates connected integrally are arranged at the lower ends of the launching cylinders, so that gunpowder is filled without splicing and is not liable to be ejected out in use, and the production efficiency is relatively high, and safety is achieved.

Description

technical field [0001] The invention relates to a firework launching device, in particular to a plastic launching pot for fireworks. Background technique [0002] Traditional firework launching devices are usually formed by bonding paper tubes. It needs to go through multiple processes such as paper cutting, rolling, drying, cutting, pressing soil to cover the back, bonding, drilling and threading to obtain the product. Complicated and relatively low production efficiency. In addition, the paper tube is prone to moisture, and the gunpowder in the paper tube is prone to moisture failure, and the gunpowder is prone to spontaneous self-explosion after moisture and heat reach a certain temperature, which poses a certain safety hazard. [0003] The Chinese invention patent application with the publication number CN101776424A discloses a plastic launch basin for fireworks, which consists of a plurality of tubular cylinders, connecting plates between the walls of each cylinder and ...

AI Technical Summary

Problems solved by technology

The plastic launch pot for fireworks is molded by injection molding, which simplifies the production process in a certain length. Compared with the paper tube, the gunpowder in the tube is not easy to be affected by moisture. However, the barrels of the plastic launch pot for fireworks are completely fixedly connected. If it is necessary to change the spraying angle of the fireworks or the graphics produced after the fireworks are sprayed, it is necessary to re-make the cylinder mold, and the production cost is relatively high; It is necessary to set each base on the corresponding barrel to load gunpowder, the production efficiency is still relatively low, and the barrel may be ejected during use, posing a safety hazard
