Problems solved by technology

[0006] The technical problem to be solved by the embodiments of the present invention is that after the existing cylindrical firework paper launch tube is deformed by moisture, the paper cake and the paper tube cannot be sealed well, resulting in a decrease in the launch height of the effective medicine and a potential safety hazard. In order to solve this problem One embodiment of the present invention provides a combined firework structure inner cylinder that does not need to be covered with paper and sealed. Another embodiment of the present invention provides a combined firework structure launching tube that does not need to be covered with paper to seal.

Embodiment 1

[0066] In order to understand the improvement of the present invention more easily, this example firstly explains the launch tube of the existing cylindrical fireworks.

[0067] Such as figure 1 Shown is a single launching tube of the existing cylindrical fireworks, wherein the launching tube 10 is equipped with an inner cylinder body 30, the upper end of the inner cylinder body 30 is covered with a circular paper cake 20, and the lower end of the inner cylinder body 30 is cushioned with a lower cardboard 40, There is a lower cardboard ignition hole 41 in the center of the lower cardboard 40. The circular paper cake 20 forms a closed space between the inner cylinder 30 and the lower cardboard 40. The lower cardboard 40 is filled with a propellant layer 50. The medicine clay head seal layer 60, and the ignition lead wire 70 passes through the propellant powder layer 50 and is drawn out of the launch tube. After the propellant layer 50 is ignited by the ignition lead wire 70, t...

Embodiment 2

[0072] In order to solve the problems existing in the launch tube of the existing cylindrical fireworks in Example 1, the embodiment of the present invention provides a combined fireworks structure inner cylinder 30 that does not need to be covered with paper and sealed, such as Figure 4 As shown, the inner cylinder 30 has upper and lower ends, and a cylinder wall 33 connected to the upper and lower ends;

[0073] The upper end 31 of the inner cylinder is a closed structure, and the lower end 32 of the inner cylinder is an open structure;

[0074] The shape of the inner cylinder 30 is cylindrical or conical;

[0075] A supporting mechanism 34 is disposed on the cylinder wall 33 .

[0076] The material of the inner cylinder 30 is plastic material, preferably recycled plastic.

[0077] Adopt the combination firework of above-mentioned technical scheme to use inner cylinder 30, when filling, as Figure 5 As shown, the inner cylinder body 30 is first turned upside down, the in...

Embodiment 3

[0088] This example provides a kind of combined firework structure launching tube that does not need to be sealed with paper cakes, such as Figure 13 As shown, the launch tube includes

[0089] The inner cylinder 30 of Embodiment 2; and

[0090] The launch tube 10 matched with the inner cylinder 30;

[0091] The upper end of the launch tube 10 is an opening, and the bottom of the launch tube 10 is provided with an ignition hole 11 communicating with the inside and outside of the launch tube 10;

[0092] A firing chamber 80 filled with propellant is formed between the bottom of the firing cylinder 10 and the lower opening 32 of the inner cylinder;

[0093] When the inner cylinder 30 is pressed into the launch tube 10, the inner wall of the launch tube 10 is deformed under the action of the support mechanism 34, so that the inner cylinder 30 is blocked in the launch tube 10, and the outer diameter of the inner cylinder 30 0.2-3.0 mm smaller than the inner diameter of the lau...

Abstract

The embodiment of the invention provides a combined firework structure inner barrel body and launching barrel without covering a circular paper cover for sealing, the problems that the circular papercover cannot be connected with a paper barrel in a completely sealed mode after an existing cylindrical firework launching barrel is affected with damp and deformed, so that the emission height of effect powder is reduced, and potential safety hazards exist are solved. During operation, a supporting mechanism can increase the friction between the outer surface of the barrel wall of the inner barrel and the inner wall of the launching barrel, the supporting mechanism is in friction with the inner wall of the launching barrel so as to increase the resistance when the inner barrel is launched outward, the resistance enables the pressure generated by ignited propellant to be pressurized in the launching barrel, firepower of the propellant is fully released when the inner barrel is launched outof the launching barrel, so that the launching effect is better, compared with a launching barrel with the same size, the launching height is higher, or if the same launching height can be reached, the height of the required launching barrel and the amount of the propellant can be reduced by half or more.

Description

technical field [0001] The invention belongs to the technical field of fireworks and firecrackers, and in particular relates to a combined fireworks structure inner cylinder and launching cylinder that do not need to be covered with paper and sealed. Background technique [0002] Fireworks have a long history in our country and are deeply loved by people for their brilliance and variety. According to the national standard GB19593-2015 "Fireworks and Firecrackers Combination Fireworks", a combination of fireworks refers to a combination of two or more small fireworks, spray flowers, or beads of the same or different types of fireworks. According to the type of combination, it can be divided into two types: same combination fireworks and different types of combination fireworks. The combination of small fireworks can be divided into five types according to the structure, shape and launch form of the rising effect parts: cylindrical type, spherical type, drug column type, drug...
