Plastic combined firework

Abstract

The invention relates to plastic combined firework. The plastic combined firework comprises a plurality of plastic transmitting pipes and plastic bases, wherein each plastic transmitting pipe is a hollow barrel body with a plastic bottom plate at one end; a connection hole is formed in the centre of each plastic bottom plate; and each plastic transmitting pipe is located above the corresponding plastic base, and the bottom end of the plastic transmitting pipe is installed on the corresponding plastic base. A connection device is arranged at the centre of each plastic base; and each connection device stretches into the connection hole in the centre of the corresponding plastic bottom plate, and forms clamping fit with the connection hole. According to the plastic combined firework disclosed by the invention, a lead wire is high in installation speed and not liable to be wetted, and high safety is achieved.

Description

technical field [0001] The invention relates to a combined fireworks, in particular to a plastic combined fireworks. Background technique [0002] Existing combination fireworks generally all adopt paper material to make, are combined by some launching tubes with yellow mud bottom, are bundled with fiber ropes, bonded with glue, and integrally pressed and formed with moulds. Due to the complex production process of paper fireworks: cutting paper, rolling paper tube, crushing soil, mixing primer, bottoming mud, cooling, bonding single tubes into a row, taper holes, connecting fuses, sticking fire paper, The rows are bonded together into a whole, and the whole is fastened with wire or tape. The process is cumbersome and complicated, and is greatly affected by the weather. In case of continuous rain, snow, severe winter and other weather, the paper tube and mud bottom cannot be dried in time, and the subsequent processes cannot be carried out. [0003] Therefore, someone has ...

AI Technical Summary

Problems solved by technology

[0004] However, the main body of this plastic combined firework has the disadvantages that the base is bulky and the combination of the base and the launch tube is not matched. In particular, the lead wire connection between the launch tube and the launch tube is inconvenient. It is connected and inserted into the fuse hole at the bottom of another adjacent launch tube, and the lead wire needs to be fixed on the bottom of the launch tube by gluing or other means, which requires a lot of labor and low work efficiency, and becomes a plastic combination A Production Bottleneck for Fireworks

In addition, the main body of this kind of plastic composite fireworks also has problems such as exposed leads, easy to be affected by moisture, poor safety, poor contact of propellant powder, easy to extinguish the flame, and easy to explode the tube.
