Abstract

The utility model discloses a lift-off rocket firework capable of improving flight stability, which comprises a chimney, three secondary leads for simultaneously igniting are arranged below the chimney, and the bottoms of the secondary leads are connected with connecting leads; the supporting rod in the center of the bottom of the chimney is inserted into the hollow carrying rod of the carrying table, the multiple spirally-wound main leads are ignited, the three auxiliary leads are ignited through the connecting leads at the same time, the triangular arc-shaped chimney is driven to keep in the continuous upward direction in the carrying rod, and meanwhile the semicircular top shell reduces wind resistance till the chimney rises to the sky. The large dosage of gunpowder enables the rocket fireworks which rise off to stably keep the linear rising effect.

Description

Technical Field

[0001] This utility model relates to the field of fireworks technology, and in particular to a rocket firework that improves flight stability. Background Technology

[0002] Traditional rocket fireworks are often affected by various factors during launch, such as wind direction, wind speed, and the instability of gunpowder formula, making the rocket's flight trajectory unpredictable and causing the fireworks' trajectory to deviate. This not only affects the audience's viewing experience but may also pose a safety hazard to the surrounding environment. Therefore, a rocket fireworks design to improve flight stability is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides an aerial rocket firework that improves flight stability, comprising a smoke tube, three secondary fuses that ignite simultaneously below the smoke tube, and a ring-shaped connecting fuse at the bottom of each secondary fuse.

[0004] Furthermore, a spirally wound main lead is arranged in a circular array below the connecting lead, and a circular support rod is connected to the middle of the main lead.

[0005] Furthermore, a matching platform is provided at the bottom of the support rod, and a hollow support rod is provided at the top of the platform. The support rod is inserted into the hollow support rod.

[0006] Furthermore, the chimney is triangular in shape, with a gunpowder cartridge located at one corner of the triangle, and each cartridge containing the same type of gunpowder.

[0007] Beneficial effects: Inserting the support rod at the center of the bottom of the smoke tube into the hollow support rod of the platform ignites multiple spirally wound main fuses, causing three secondary fuses to be ignited simultaneously by the connecting fuses. This drives the triangular arc-shaped smoke tube to maintain a continuous upward direction within the support rod. At the same time, the semi-circular top shell reduces wind resistance until it ascends into the air. The high amount of gunpowder enables the rocket fireworks to maintain a stable, straight upward trajectory.

[0008] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0012] Please refer to Figures 1 to 2 ;

[0013] This embodiment provides a rocket firework for improving flight stability, including a smoke tube 1, three secondary fuses 102 that ignite simultaneously are arranged below the smoke tube 1, and a ring-shaped connecting fuse 103 is connected to the bottom of the secondary fuses 102; Reference Figure 1 and Figure 2 Below the connecting lead 103, there is also a spirally wound main lead 104 arranged in a circular array. A circular support rod 2 is connected to the middle of the main lead 104. A matching platform 3 is also provided at the bottom of the support rod 2. A hollow carrier rod 301 is provided at the top of the platform 3. The support rod 2 and the hollow carrier rod 301 are inserted into each other. The chimney 1 is triangular arc-shaped. A gunpowder cartridge is provided at one corner of the triangle of the chimney 1. Each gunpowder cartridge is filled with the same gunpowder.

[0014] In a specific embodiment, the support rod 2 at the center of the bottom of the chimney 1 is inserted into the hollow carrier rod 301 of the platform 3. The multiple spirally wound main fuses 104 are ignited, and the three secondary fuses 102 are simultaneously ignited by the connecting fuses 103. This causes the gunpowder cartridges in each corner of the triangular arc-shaped chimney 1 to be ignited by the secondary fuses 102 and to maintain a continuous upward direction within the carrier rod 301. At the same time, the semi-circular top shell 101 reduces wind resistance until the rocket takes off. With a large amount of gunpowder, the rocket fireworks can maintain a stable, straight upward trajectory.
