When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please combine Figures 1 to 5 As shown, a tumbling firework 100 provided in one embodiment of the utility model comprises a square box body 10 and a firework tube fixed in the box body, and a firework outlet 11 corresponding to the firework tube is opened on the box body 10;

[0032] The fireworks tube includes at least one first fireworks tube 21 arranged vertically, and at least one second fireworks tube 22 arranged horizontally; the second lead 221 of the second fireworks tube 22 is connected to the first lead 211 or the flame outlet of the first fireworks tube 21;

[0033] The tumbling firework 100 further includes a bouncing structure 301 and a bouncing fuse 302 . The bouncing structure 301 includes a sleeve 31 , a spring 32 , and an inner core 33 .

[0034] The sleeve 31 is fixed in the box body 10 along the vertical direction. The sleeve 31 is in the shape of a hollow rod. The sleeve 31 includes a first opening 311 and a second opening 312 that are arranged opposite to each other. An ejection outlet 111 is provided on the bottom surface of the box body 10. The second opening 312 is arranged corresponding to the ejection outlet 111. A retaining wall 313 is arranged on the inner wall of the first opening 311 of the sleeve 31.

[0035] A blocking ring 333 is arranged on the outer wall of the middle part of the inner core 33. The inner core 33 comprises a top end 331 and a bottom end 332 which are arranged opposite to each other. A threading hole 334 is provided on the top end 331. The distance between the top end 331 of the inner core 33 and the blocking ring 333 is smaller than the natural length of the spring 32. The top end 331 of the inner core 33 passes through the spring 32 and extends into the sleeve 31 from the second opening 312 and extends from the first opening 311. The spring 32 is held between the blocking wall 313 and the blocking ring 333 and is in a compressed state. The length of the inner core 33 corresponds to the length of the sleeve 31.

[0036] One end of the bounce fuse 302 is connected to the first fuse 211 or the flame outlet of the first firework tube 21, and the other end passes through the threading port 334. The bounce fuse 302 clamps the top end 331 of the inner core 33 to prevent the inner core 33 from popping out from the second opening 312 under the action of the spring 32. After the bounce fuse 302 is ignited and burns to the threading port 334, the inner core 33 pops out from the second opening 312 under the action of the spring 32.

[0037] Specifically, in one embodiment, the opening diameter of the first opening 311 is smaller than the spring, and the outer wall of the sleeve body at the first opening 311 of the sleeve body 31 naturally forms the blocking wall 313. Optionally, in other embodiments, a protrusion may be specially provided on the inner wall at the first opening 311 of the sleeve body 31 to form the blocking wall 313.

[0038] Specifically, the length of the inner core 33 can be the same as the length of the sleeve 31, or slightly longer than the length of the sleeve 31. Generally speaking, as long as the inner core 33 is burned after the spring fuse 302 is burned, the bottom 332 of the inner core 33 contacts the ground under the force of the spring 32, and the spring 32 is still in a compressed state, which will give a reverse force to the sleeve 31 (that is, the box body 10 connected together), so that the box body 10 can be turned over.

[0039] In the tumbling fireworks 100 of the present invention, after the first fuse 211 of the first fireworks tube 21 is ignited, the first fireworks tube 21 is ignited first; because the second fuse 221 of the second fireworks tube 22 is connected to the first fuse 211 or the flame outlet of the first fireworks tube 21, the second fuse 221 of the second fireworks tube 22 will also be ignited. After the burning is completed, the second fireworks tube 22 will start to be ignited after the first fireworks tube 21 has been ignited for a certain period of time; at the same time, one end of the bouncing fuse 302 is connected to the first fuse 211 or the flame outlet of the first fireworks tube 21, and the bouncing fuse 302 also starts to be ignited at the same time. After the bouncing fuse 302 is burned, the inner core 33, under the force of the spring 32, gives a reverse force to the sleeve 31 (that is, the box body 10 connected together), so that the box body 10 will flip over. The combination of multiple actions increases the fun of ignition. In addition, by controlling the lengths of the first lead 211 , the second lead 221 and the bounce lead 302 , the firing time of the second firework tube 22 and the turning time of the box body 10 can be adjusted.

[0040] Preferably, a third firework tube 23 capable of emitting sound is further disposed in the box body 10 , and a third lead 231 of the third firework tube 23 is connected to the flame outlet or the gunpowder core of the first firework tube 21 .

[0041] Preferably, the third fuse 231 of the third firework tube 23 is connected to the flame outlet of the first firework tube 21, and the length of the third fuse 231 of the third firework tube 23 is the same as the length of the bounce fuse 302, or the burning time is the same. Specifically, the time when the bounce fuse 302 burns to the threading port 334 and the burning time of the third firework tube 23 can be made close by adjusting the length and setting position of the third fuse 231, so as to produce an explosion effect before and after the flip.

[0042] Preferably, the box body 10 is further provided with a through hole 112, and the through hole 112 is covered with a transparent plastic film. When the third firework tube 23 explodes, the film can be broken through to produce a smoke effect.

[0043] Preferably, paper scraps or sequins are also contained in the box body 10. When the third firework tube 23 explodes, it can break through the film, produce smoke effects and spray out paper scraps. Special paper scraps can be colorful shredded paper, which can produce beautiful explosion effects.

[0044] Preferably, a counterweight 40 is bonded to the inner bottom surface of the box body 10 .

[0045] Preferably, the counterweight 40 is disposed at the bottom of the first fireworks tube 21 .

[0046] Preferably, the box body 10 is square.

[0047] Preferably, the firing time of the first firework tube 21 is greater than the firing time of the second firework tube 22, the length of the second fuse 221 of the second firework tube 22 is the same as the length of the bouncing fuse 302, or the burning time of the second fuse 221 of the second firework tube 22 is the same as the burning time of the bouncing fuse 302. Thus, the flipping effect of the second firework tube 22 is produced almost at the same time. It can be understood that here, by adjusting the fuse length, the firing rhythm can be adjusted, which does not mean that it must be completely consistent, as long as the error is within the allowable range.

[0048] Preferably, the diameter of the bounce fuse 302 is greater than half of the difference between the inner diameter of the first opening 311 and the outer diameter of the top 331. That is, the thickness of the two folded bounce fuses 302 plus the diameter of the top 331 can already hold the inner core 33, so that the inner core 33 will not fall out of the sleeve 31; a thicker rubber-impregnated cotton fuse rope wrapped with gunpowder can also be used. Such a fuse rope has a higher hardness and is not easy to bend, so that the bounce fuse 302 can hold the inner core 33. Those skilled in the art can design it according to needs.

[0049] Preferably, the sleeve body 31 and the inner core 33 can be made of plastic material.

[0050] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the protection scope of the present invention.
