[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please refer to Figure 1-5 A fireworks display device includes a turntable 1 and multiple fireworks tubes 15. The multiple fireworks tubes 15 are fixed to the turntable 1 by an array of hollow bolts. The hollow bolts ensure that the fireworks tubes are connected vertically. A connecting tube 16 is provided around the circumference of each fireworks tube 15. A rotating shaft 9 is provided at the center of the turntable 1. The rotating shaft is a hollow shaft, which facilitates the passage of wires inside. The upper and lower wires of the turntable are connected by a slip ring to prevent wire tangling. A bearing 10 and a swing rod 11 are fixed on the outer circumference of the rotating shaft 9. The swing rod 11 can rotate around the rotating shaft 9 through the bearing 10. A cylinder 12 is provided at the bottom of the swing rod 11. A conical trigger end 13 is provided at the output end of the cylinder 12. After the cylinder 12 is operated, the trigger end 13 extends into the surrounding connecting tube 16.

[0024] The interface between the connecting tube 16 and the firework tube 15 is provided with a reed switch magnetic control switch 161, and the end of the trigger head 13 is provided with a magnet that cooperates with the reed switch magnetic control switch 161.

[0025] When in use, the turntable 1 rotates at a low speed, and the firework tubes 15 rotate with the turntable 1. Each firework tube 15 is filled with colored paper. When the control button is pressed, the cylinder 12 runs and the trigger end 13 extends quickly. When the trigger end 13 is accurately inserted into the connecting tube 16, the reed switch magnetic control switch 161 is opened. After it is opened, the control valve opens the gas cylinder, causing the internal pressurized gas to be ejected, thereby spraying out the colored paper in the firework tube 15, achieving the effect of entertainment and creating an atmosphere.

[0026] In this embodiment, tension springs 14 are also connected to both sides of the swing rod 11. The tension springs 14 on both sides have two functions: first, to maintain the initial stability of the swing rod 11 by using the tension springs 14 on both sides; and second, when the conical trigger end 13 touches the side wall of the connecting cylinder 16, the swing rod 11 will swing slightly, thereby achieving length compensation on both sides.

[0027] In this embodiment, the top of the firework tube 15 is open, and the bottom end passes through the turntable 1 and is connected to the angle seat valve 18. The firework tube 15 is connected to the gas cylinder 17 through the angle seat valve 18. A flow limiting valve 19 is provided on one side of the port of the gas cylinder 17. External gas is injected into the gas cylinder 17 through the pipeline and the flow limiting valve 19. After the air enters the gas cylinder 17, it generates a certain pressure, which provides power for the subsequent spraying of colored paper.

[0028] Specifically, the angle seat valve 18 includes a valve cylinder 181, with a pneumatic port 182 on its circumference. The output end of the valve cylinder 181 extends into the valve cylinder 183. The operation of the valve cylinder 181 can control the opening and closing of the valve cylinder 183. The valve cylinder 183 has a first connection port 184 and a second connection port 185 at both ends. The first connection port 184 is connected to the fireworks tube 15, and the second connection port 185 is connected to the gas cylinder 17.

[0029] Please refer to Figure 6 Before use, the angle seat valve 18 is closed, at which time outside air enters the gas cylinder 17 through the pipeline and the flow limiting valve 19;

[0030] During play, cylinder 12 operates and causes trigger end 13 to extend rapidly. When trigger end 13 is not inserted into connecting cylinder 16, one stroke ends.

[0031] Please refer to Figure 7 When the trigger end 13 is inserted into the connecting cylinder 16, the magnet at the end of the trigger end 13 will trigger the reed switch magnetic control 161. The reed switch magnetic control 161 controls the operation of the valve cylinder 181 through the signal line. After the valve cylinder 181 is operated, the valve cylinder 183 opens. At this time, the pressurized gas in the gas cylinder 17 is sprayed out instantly, and the colored paper inside is sprayed out at the same time to meet the needs of entertainment and play.

[0032] After the spray is released, the trigger end 13 disengages from the connecting cylinder 16. At this time, the reed switch magnetic control 161 and the valve cylinder 181 close. Then, air is injected into the gas cylinder 17 through the pipeline and the flow limiting valve 19, and so on for repeated use.

[0033] The colored paper inside the firework tube 15 can be filled manually.

[0034] In this embodiment, the angle seat valve 18 is preferably a pneumatically controlled angle seat valve, and the reed switch magnetic control switch 161 is preferably a GPS-01 reed switch. It is understood that the angle seat valve 18 can also be replaced by a manual slide valve, which is controlled by a cylinder to open and close. Of course, other valves or control switches of the same type can also be used, as long as they can be used.

[0035] As a preferred embodiment, a connecting plate 2 is provided below the turntable 1. The connecting plate 2 is fixed to the turntable by a square tube and bolts. The connecting plate 2 is fixedly connected to the gear disk 5 by a main shaft 3. A base 4 is provided below the gear disk 5. A motor 7 is mounted on the base 4. The motor is preferably a servo motor. A drive gear 8 is fixed to the output end of the motor 7. The drive gear 8 meshes with the gear disk 5. Multiple support bearings 6 are fixed on opposite sides of the connecting plate 2 and the base 4. The circumference of the support bearings 6 is in contact with the upper and lower surfaces of the gear disk 5. When the gear disk 5 rotates, the surrounding support bearings 6 rotate accordingly, which can achieve a good rotation and support effect.

[0036] When in use, the motor 7 is started, and the drive gear 8 drives the turntable 1 to rotate. The rotation of the turntable 1 drives the surrounding firework tubes 15 to rotate. In conjunction with the trigger end 13, etc., colored paper can be sprayed, producing a good entertainment effect and atmosphere.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
