Description

Technical Field

[0001] The utility model relates to a combined firework inner tube. Background Art

[0002] Combination fireworks are fireworks products composed of multiple outer tubes, and the inner tube is loaded into the inner cavity of the outer tube. The inner tube needs to be filled with two kinds of pyrotechnics, namely, bursting charge and effect charge. The bursting charge is ignited by the over-fire fuse and explodes after being launched to high altitude, causing the tube to break and ignite and throw out the effect charge; the effect charge displays a preset fireworks effect at high altitude. The effect charge (Pyrotechnic charge) is a pyrotechnic charge used to produce effects such as light, sound, color, shape, and smoke. The effect charge in the inner tube generally exists in the form of bright beads, charge columns, etc., and is also called effect parts in the industry. The bottom end of the inner tube is closed with a mud head layer formed by a mud and mud head layer pressing mold, and the upper end is closed with a solid priming agent or cardboard (paper baba).

[0003] In order to achieve the annular effect in the air through a single inner tube, combined fireworks usually use a cylindrical component added to the center of the inner tube in the prior art, such as the central cartridge in the "pyrotechnic powder positioning mechanism of a combined firework inner tube" disclosed in the Chinese invention patent document with the authorization announcement number CN 106895747 B; the central tube of the "firework structure with an annular effect in the air" disclosed in the Chinese invention patent document with the application publication number CN 111649627A; the central tube cavity of the "firework inner tube with a two-color annular effect" disclosed in the Chinese utility model patent document with the authorization announcement number CN 215725474 U, etc.

[0004] The disadvantage of the prior art is that a single inner tube can only achieve a single annular effect, resulting in a monotonous firing effect of the product. Utility Model Content

[0005] In order to solve the above-mentioned drawbacks, the technical problem to be solved by the present invention is to provide a combined firework inner cylinder that can realize the combination of annular effect and other effects. In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a combined firework inner cylinder that combines annular effect and other effects, including an inner cylinder with an inner cavity filled with bursting powder and effect parts, the inner cylinder is provided with an upper port sealing layer and a bottom port sealing layer, the bottom port sealing layer is installed with a pyrotechnic fuse, characterized in that the effect parts include annular effect parts and other effect parts, the annular effect parts are installed in a positioning ring, between the inner ring wall and the outer ring wall of the positioning ring is an annular groove for loading a plurality of annular effect parts, and the inner ring wall is a through hole structure; other effect parts are loaded in the inner cylinder above and / or below the annular effect parts.

[0006] The beneficial effects of the present utility model are that when the combined fireworks inner cylinder provided by the present utility model is ignited, a single inner cylinder can achieve the combination of a circular effect and other effects, and construct more types of aerial ignition shapes.

[0007] In one embodiment, the depth of the circular groove is set corresponding to the size of a single circular effect element, and a layer of circular effect elements is loaded in the circular groove. When ignited, the contrast between the circular effect presented by the effect elements and other effects is more obvious.

[0008] In one embodiment, the circular effect elements are embedded and fixed in the circular groove. This avoids the circular effect elements falling off from the circular groove during installation.

[0009] In one embodiment, the effect elements are buried in the blasting powder. This ensures that the blasting powder transfers fire to ignite each effect element.

[0010] In one embodiment, the other effect elements include a first effect element and a second effect element, and the first effect element and the second effect element are respectively located above or below the circular effect element.

[0011] Of course, when implementing any product of the present utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously.

[0023] See attached Figures 1-5 , reflecting a specific structure of the utility model. The inner tube of the combined fireworks with the annular effect and other effects comprises an inner tube 2 in which the inner cavity is filled with bursting charge 1 and effect parts. In the example, the effect parts are buried in the bursting charge 1, so as to ensure that the bursting charge 1 transmits fire to ignite each effect part. The inner tube 2 is provided with an upper port sealing layer 3 and a bottom port sealing layer 4, and the bottom port sealing layer 4 is provided with a pyrotechnic fuse 5.

[0024] In the example, the effect piece includes the annular effect piece 6 and other effect pieces, and the other effect pieces refer to effect pieces that are different from the firing effect of the annular effect piece 6. The firing effect includes two aspects: shape (such as willow, flash, wave, coconut, crown, etc.) and light color (such as gold, silver, red, green, etc.), and both aspects can be different, or only one aspect can be different. The other effect pieces in the example include the first effect piece 7 and the second effect piece 8.

[0025] The annular effect member 6 is installed in the positioning ring 9, and between the inner ring wall 901 and the outer ring wall 902 of the positioning ring 9 is an annular groove 903 for loading eleven annular effect members 6, and the inner ring wall 901 is a through hole 904. In the example, the depth of the annular groove 903 is set corresponding to the diameter of a single annular effect member 6, so that only one layer of annular effect members 6 can be loaded in the annular groove 903. When the fireworks are set off, the annular effect presented by the annular effect member 6 is more obvious in contrast to other effects.

[0026] During production, the annular effect member 6 is first installed in the positioning ring 9, and then the positioning ring 9 loaded with the annular effect member 6 is placed in the inner cylinder. In the example, the width of the annular groove 903 is set corresponding to the diameter of a single annular effect member 6, and the matching gap between the two is a tight fit. The annular effect member 6 is embedded and fixed in the annular groove 903. The annular effect member 6 is prevented from falling off from the annular groove 903 during installation. This is convenient for production.

[0027] In the example, the first effect member 7 is located above the annular effect member 6, and the second effect member 8 is located below the annular effect member 6. In other embodiments, only one other effect member may be provided, which may be located above or below the annular effect member 6.

[0028] When the inner cylinder of the combined fireworks provided by the present utility model is ignited, a single inner cylinder can achieve the combination of a circular effect and other effects. Compared with the single circular effect of the prior art, more types of aerial firing shapes can be constructed.

However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
