Problems solved by technology

[0002] The traditional fireworks tube is a paper fireworks tube, and then the paper is connected as a whole through manual pasting. The most obvious feature of the artificially pasted fireworks tube is that the main material of the fireworks tube is hard paper, and it is produced during the manual pasting process. The efficiency is very low, the cartridge bottom plug of the existing firework tube is as large as the diameter of the firework tube, and the powder charge is very large, causing a lot of waste

Embodiment l

[0011] as attached figure 1 As shown, a firework tube with a concave cartridge bottom plug includes a cylindrical outer tube 1, an inner tank 2, and a bottom plug 5. The inner tank is provided with an upper cover 3 and a lower cover 4, and the bottom plug 5 is located on the lower cover 4. Below, there is a concave cartridge in the middle of the bottom plug 5. The concave cartridge is cylindrical in shape, and its bottom surface diameter is one-third of the bottom surface diameter of the outer cylinder. The bottom of the bottom plug 5 is also provided with a lead hole 6 to communicate with the concave cartridge. .

Embodiment 2

[0013] A one-time molding firework tube made of plant fiber, including a complete stamping part and a cartridge formed by stamping raw material powder derived from plant fiber, and a complete stamping part stamped from raw material powder derived from plant fiber. The upper side has a plurality of cartridges formed by inward depression, and the bottom plug 5 of each cartridge is provided with a concave cartridge. The concave cartridge is cylindrical, and its bottom surface diameter is one-third of the bottom surface diameter of the outer cylinder. The bottom of the bottom plug 5 is also provided with a lead hole 6 to communicate with the concave cartridge.

Abstract

The invention relates to a fireworks cylinder with a concave cartridge bottom plug. The fireworks cylinder comprises a cylindrical outer cylinder, an inner liner and a bottom plug, wherein the inner liner is provided with an upper cover and a lower cover; the bottom plug is positioned below the lower cover; the middle part of the bottom plug is provided with a concave cartridge which is cylindrical; the diameter of the bottom surface of the concave cartridge is one third of the diameter of the bottom surface of the outer cylinder; and the bottom part of the bottom plug is also provided with a leading wire hole which is communicated with the concave cartridge. According to the invention, the concave cartridge is arranged in the bottom plug, the volume of the concave cartridge is only one sixth to one fifth of the original cartridge, thus the explosive using amount is reduced greatly, and the same effect can be achieved.

Description

technical field [0001] The invention relates to a firework tube, especially a once-molded fireworks tube. Background technique [0002] The traditional fireworks tube is a paper fireworks tube, and then the paper is connected as a whole through manual pasting. The most obvious feature of the artificially pasted fireworks tube is that the main material of the fireworks tube is hard paper, and it is produced during the manual pasting process. Efficiency is very low, and the cartridge bottom plug of existing firework tube is as big as the diameter of the firework tube, and the powder charge is very large, causing great waste. Contents of the invention [0003] The object of the present invention is to provide a firework cartridge with a concave cartridge bottom plug. [0004] Technical scheme of the present invention is: [0005] A firework tube with a concave cartridge bottom plug, comprising a cylindrical outer tube, an inner tank, and a bottom plug. The inner tank is pro...
