[0045] As shown in the accompanying drawings, the present application provides a combined fireworks stand, which comprises a connecting fuse 6, a pouring assembly and a plurality of fireworks stand units; the plurality of fireworks stand units are arranged in a line, and the connecting fuse 6 is connected to the plurality of fireworks stand units in sequence, the connecting fuse 6 connects the plurality of fireworks stand units in the same fuse burning circuit, when the connecting fuse 6 is ignited, all the fireworks in the combined fireworks stand can be ignited and fired, and all the pouring assemblies are automatically triggered; Figures 11-14 At least one of the fireworks stand units is provided with a pouring assembly, the pouring assembly comprises a control fuse 2 and an elastic member 3, the elastic member 3 is arranged at the bottom of the fireworks stand unit, one end of the control fuse 2 is connected to the upstream fuse of the fuse burning circuit in the combined fireworks stand, specifically, it can be connected to the connecting fuse 6 or the fireworks, and the other end makes the elastic member 3 in a compressed state, the elastic member 3 is released after the control fuse 2 burns, and the elastic member 3 resets to push the fireworks stand unit to pour, and the pouring direction is consistent with the linear arrangement direction;

[0046]

[0047] ​By setting the stacking distance between the linearly arranged fireworks rack units, a falling fireworks rack unit can push down an adjacent fireworks rack unit; alternatively, several fireworks rack units can be tilted sequentially using the tilting assembly. Specifically, with the connecting wire 6 in a stretched state, the stacking distance between the fireworks rack units can be controlled by adjusting the length of the connecting wire 6 between two adjacent fireworks rack units, facilitating the arrangement of the modular fireworks rack during actual use. The present invention does not require manual triggering of the dumping component. By setting a control lead 2, the triggering of the dumping component is cleverly integrated into the original firing steps of the fireworks. The fireworks rack units are connected by the connecting lead 6, and the distance between the fireworks rack units can be controlled by setting the length of the connecting lead 6 between two adjacent fireworks rack units, which is convenient for stacking and improves installation efficiency. During transportation, the fireworks rack units in the combined fireworks rack can be stacked, which takes up less space and saves transportation costs. When the combined fireworks rack of the present invention is used, during the firing of the fireworks cartridge, the combined fireworks rack will present a dumping effect similar to the domino effect, which increases the fun and viewing of the fireworks. Alternatively, the time of the fireworks rack unit dumping can be controlled by controlling the burning time of the lead 2, ensuring that the fireworks rack unit dumps after the fireworks cartridge has finished firing, thereby ensuring the safety of the fireworks.

[0048] It should be noted that when the dumping assembly is provided only at the bottom of the fireworks rack unit at one end of the linear arrangement, the dumping direction of the fireworks rack unit has adjacent fireworks rack units.

The cartridge's lead is connected to the connecting lead 6. A through hole 51 is provided at the top of the fireworks stand unit, connecting to the cartridge mounting tube 4. This allows the cartridge's lead to connect smoothly to the connecting lead 6 and allows the cartridges within the cartridge mounting tube 4 to be discharged from the top of the unit. Preferably, the fireworks stand unit is a rectangular parallelepiped, with each unit containing two cartridge mounting tubes 4. Two circular through holes 51 are provided at the top of the unit, connecting the two cartridge mounting tubes 4.

It should be noted that the cartridge mounting tubes 4 can be provided in other quantities and configurations, and the fireworks stand units can also have other shapes, depending on actual display needs. Preferably, the proportions of the rectangular units of the fireworks rack are further adjusted, with the height of the units being the same as the height of the units, and the edge perpendicular to the height and in the direction of tilting being the same as the length of the units, with a height:length ratio of 2:1. This makes the units resemble dominoes more closely, and when a unit to be tilted pushes down an adjacent unit, this ratio helps ensure a perfect tilting effect. Preferably, the outer surfaces of the rectangular units are further packaged to enhance the appearance.

[0058] Or, as attached Figure 13 and 14 As shown, the firework cartridge lead groove 52 includes a transverse lead groove 521 and a longitudinal lead groove 522 .

[0059] In a preferred embodiment, Figure 13 As shown, the top of the fireworks rack unit is provided with a transverse lead groove 521 and a longitudinal lead groove 522. The transverse lead groove 521 communicates with the through-hole 51 provided at the top of the fireworks rack, while the longitudinal lead groove 522 extends longitudinally through the top of the fireworks rack unit.

Preferably, the transverse lead groove 521 is located in the center of the top of the fireworks rack unit, and the longitudinal lead groove 522 is located in the center of the top of the fireworks rack unit. The connecting fuse 6 includes ignition fuses 62 disposed in several transverse lead grooves 521 and a main fuse 61, which sequentially connects the ignition fuses 62. The main fuse 61 is disposed in the longitudinal lead groove 522, forming a fishbone-shaped connection connecting the various fireworks rack units.

Figures 6-10 As shown, in order to facilitate processing, stable placement and better control of the pouring direction, a cuboid firework base 1 is adopted, the bottom of the firework base 1 is provided with a rectangular mounting groove 11, the width of the rectangular mounting groove 11 is greater than or equal to the width of the elastic member 3, a horizontal plate 14 is arranged in the mounting groove 11 near the edge of the bottom of the firework base 1, the two ends of the horizontal plate 14 are connected with the two side groove walls of the mounting groove 11 and are parallel to the groove bottom of the mounting groove 11, the distance between the horizontal plate 14 and the groove bottom of the mounting groove 11 is greater than or equal to the diameter of the connecting torsion arm 31 of the elastic member 3, and a square mounting hole 13 is formed between the horizontal plate 14 and the mounting groove 11; the connecting torsion arm 31 of the elastic member 3 passes through the mounting hole 13 and penetrates toward the edge of the bottom of the firework base 1, and the free torsion arm 32 can freely move outside the horizontal plate 14. One end of the first control lead groove 12 is vertically communicated with the mounting groove 11 and the other end penetrates out of the edge of the bottom of the firework base 1, and one end of the control lead 2 enters the mounting groove 11 from the first control lead groove 12. As shown in FIG. 3, the other end of the control lead 2 is wound on the elastic member 3. Figure 7 and 8 As shown, in the compressed state of the elastic member 3, the control lead 2 is wound around the outside of the free torsion arm 32 in the radial direction, is then wound around the connecting torsion arm 31, and finally penetrates between the connecting torsion arm 31 and the groove bottom of the mounting groove 11. The connecting torsion arm 31 applies a force to the control lead 2 to the groove bottom of the mounting groove 11, so that the control lead 2 is clamped and fixed between the connecting torsion arm 31 and the groove bottom of the mounting groove 11, thereby maintaining the compressed state of the elastic member 3. Preferably, the distance between the horizontal plate 14 and the groove bottom of the mounting groove 11 is equal to the diameter of the connecting torsion arm 31 of the elastic member 3, so that the connecting torsion arm 31 can be clamped in the mounting hole 13, and the elastic member 3 can better abut against the firework base 1 after being expanded. In order to compress the elastic member 3, the control lead 2 is in a taut state. As shown in FIG. 4, the other end of the control lead 2 is wound on the elastic member 3.
