Description

Technical Field

[0001] This utility model relates to the field of fireworks display technology, specifically a suspended fireworks display tower. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, and firecrackers, were first put into practical use by the Chinese working people and are often used in grand ceremonies or performances. Currently, when setting off fireworks, due to the dense buildings in cities, the explosion height of aerial explosive fireworks is less than the height of the buildings, which can easily damage windows or cause fires. Secondly, fireworks have traditionally been set off from the ground, limiting their launch height and lacking visual appeal. To overcome these shortcomings, suspended fireworks towers have emerged, using drones to lift the towers to high altitudes for direct high-altitude fireworks launches, improving both safety and visual appeal. However, existing suspended fireworks towers often cannot be quickly disassembled from drones, making it inconvenient to repair or replace ammunition, thus hindering their use. Therefore, a new type of suspended fireworks tower is proposed. Utility Model Content

When it is necessary to repair the fireworks display tower body 6 or replace the ammunition, the pull ring 196 can be pulled to the left to move the pull rod 194, the slider 192 and the positioning block 193 to the left, so that the positioning block 193 can be moved out of the positioning groove 18, thereby releasing the position restriction on the rotating shaft 14. Then, the handwheel 17 can be turned to drive the rotating shaft 14 and the drive The moving bevel gear 15 rotates, which in turn drives the threaded rod 9 to rotate via the driven bevel gear 16. During the rotation of the threaded rod 9, the two fixed blocks 11 move relative to each other, causing the two fixed blocks 11 to move out of the two fixed slots 10 respectively, thereby releasing the fixation between the two connecting blocks 4 and the rectangular block 2. At this time, the two connecting blocks 4 can be pulled downward from the two connecting slots 3, and the fireworks display tower body 6 can be disassembled from the drone 1, which facilitates the fault inspection or ammunition replacement operation of the fireworks display tower body 6.

[0026] In summary, this suspended fireworks display tower, by pulling the pull ring 196 to the left, moves the pull rod 194, slider 192, and positioning block 193 to the left, causing the positioning block 193 to move out of the positioning groove 18, thereby releasing the position restriction on the rotating shaft 14. Then, the handwheel 17 can be turned to rotate the rotating shaft 14 and the drive bevel gear 15, which in turn drives the threaded rod 9 to rotate via the driven bevel gear 16. During the rotation of the threaded rod 9, the two fixed blocks 11 move relative to each other, causing the two fixed blocks 11 to move out of the two fixing grooves 10 respectively. By releasing the fixation between the two connecting blocks 4 and the rectangular block 2, and then pulling the two connecting blocks 4 downwards from the inside of the two connecting slots 3, the fireworks display tower body 6 can be disassembled from the drone 1. This achieves the purpose of easy disassembly, which facilitates the troubleshooting or ammunition replacement of the fireworks display tower body 6. It solves the problem that in the actual use of existing suspended fireworks display towers, the fireworks display tower and the drone are often unable to be quickly disassembled, making it inconvenient to troubleshoot or replace ammunition, thus hindering the use of the fireworks display tower.
