[0032] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figures 1 to 3 The utility model provides a deployable rotating firework, which may specifically include a base 10, a rotating base 20 whose bottom end is rotatably mounted on the base 10, and a firework box 30 mounted on the rotating base 20 and used to accommodate a plurality of firework tubes (not shown). During assembly, the ejection port of the firework tube needs to be aligned with the corresponding ejection hole. Among them, a lateral ejection hole 33 is provided on the side of the firework box 30. When the firework tube aligned with the lateral ejection hole 33 is ejected and fired, the firework box 30 can rotate based on the axis of the rotating base 20. In a preferred embodiment, lateral ejection holes 33 are respectively provided on two opposite sides of the firework box 30, one of the lateral ejection holes 33 is specifically located on the left side of the front side of the firework box 30 (correspondingly, the lateral ejection direction F1 extends in the horizontal direction and does not intersect with the vertical axis rotation of the rotating base 20), and the other lateral ejection hole 33 is specifically located on the rear side of the firework box 30, and the front side view of the firework box 30 (see Figure 2 ) is identical to the rear side view of fireworks box 30.

[0037] When at least one of the fireworks tubes aimed at the side injection hole 33 is ejected, a reverse thrust can be generated to drive the fireworks box 30 to rotate around the axis of the rotating base 20. Moreover, when multiple fireworks tubes that can generate the same direction of rotational driving force are fired at the same time, the rotation speed of the fireworks box 30 can be accelerated, thereby producing a gorgeous firing effect. In addition, a top injection hole 34 is opened on the top of the fireworks box 30, and its injection directions F2 and F3 are shown in FIG. Figure 1 In actual use, it can be designed to ignite the top firework tube first, and then the side firework tube, or it can also be designed to ignite them in reverse or at the same time, thereby enriching the visual effect of the fireworks.

[0038] In this utility model, refer again to Figure 1 and Figure 2The fireworks box 30 includes an installation sub-box 31 and a plurality of splicing sub-boxes 32. The installation sub-box 31 is installed on the rotating seat 20. The plurality of splicing sub-boxes 32 are divided into at least one group. One of the splicing sub-boxes 32 in each group is connected to the installation sub-box 31 and all the splicing sub-boxes 32 in the same group are connected in sequence. The installation sub-box 31 and all the splicing sub-boxes 32 can be spliced ​​and assembled into the fireworks box 30. And, see Figure 5 The fireworks box 30 can be unfolded, and the unfolded installation sub-box 31 and the plurality of splicing sub-boxes 32 are connected in a row. Among them, at least one splicing sub-box 32 is provided with a post-expansion injection hole 35. When the splicing sub-box 32 is unfolded and the post-expansion injection hole 35 is exposed, the fireworks tube aimed at the post-expansion injection hole 35 can be ejected and ignited (see Figure 5 The spray directions F4, F5, F6 and F7 in the fireworks display are increased, thereby increasing the fireworks display effect and structural deformation to enhance the fun of fireworks display.

[0039] In a preferred embodiment, the plurality of splicing sub-boxes 32 are divided into two groups (preferably evenly divided), and a connection hole 36 ( Figure 5 When the installation sub-box 31 and all the splicing sub-boxes 32 are assembled into a fireworks box 30, the connection holes 36 on the two groups of splicing sub-boxes 32 can overlap with each other and can be connected and fastened by wires to keep the two groups of splicing sub-boxes 32 in a state of being connected. Figure 1 and Figure 2 The fuse here can be designed to be relatively long so as to play a delay role, and the fuse can be connected to the top firework tube or the side firework tube, so that after the top firework tube or the side firework tube is ignited, the fuse that fastens the two groups of connection holes 36 can be burned off, so that the multiple spliced ​​sub-boxes 32 can be unfolded into Figure 5 Moreover, the fuse of the firework tube aimed at the post-expansion injection hole 35 can also be designed to be relatively long and connected to the fuse of the fastening connection hole 36. Therefore, after the multiple splicing sub-boxes 32 are unfolded, the firework tube aimed at the post-expansion injection hole 35 starts to spray and ignite, thereby making the fireworks firing effect more layered.

[0040] It should be noted that the installation sub-box 31 and the splicing sub-box 32 can be in a variety of different shapes, as long as they can be spliced ​​and assembled and unfolded during the firing process. Among them, the installation sub-box 31 and the splicing sub-box 32 can be preferably a triangular prism, which includes two triangular bottom surfaces d and a first side surface a ( Figure 5 The side faces close to the left of all triangular prisms are the first side face a) and the second side face b) Figure 5 The side faces close to the right of all triangular prisms are the second side face b) and the third side face c ( Figure 5The side surface of the bottom of all the triangular prisms is the third side surface c), the first side surface a of any triangular prism and the second side surface b of the adjacent triangular prism can fit each other, and be assembled into a polygonal fireworks box 30, and the side edges of the third side surfaces c of adjacent triangular prisms are connected in sequence. After the assembly and splicing are completed, the triangular bottom surfaces d located at the front side of the multiple triangular prisms constitute the front bottom surface of the polygonal fireworks box 30, and the triangular bottom surfaces d located at the rear side of the multiple triangular prisms constitute the rear bottom surface of the polygonal fireworks box 30, and the third side surfaces c of the triangular prisms correspond to the various side surfaces of the polygonal fireworks box 30. Among them, each triangular prism can preferably have the same size, so the shape after splicing and assembly and after unfolding is very beautiful. Moreover, since the fireworks box 30 can preferably be a paper box, multiple triangular prisms connected in sequence can be obtained by origami of cut hard shell paper. In a preferred embodiment, see Figure 1 , Figure 2 and Figure 5 The firework box 30 may be a seven-prism, and the six splicing sub-boxes 32 are evenly divided into two groups, which are symmetrically distributed on opposite sides of the installation sub-box 31 after being unfolded.

[0041] In order to prevent the fireworks tubes aimed at the rear-expanded injection holes 35 from interfering with each other during the injection and ignition, the rear-expanded injection holes 35 are arranged on the opposite sides of the adjacent spliced ​​sub-boxes 32. Figure 5 The expanded spray holes 35 are respectively arranged on the first side a (corresponding to the spray direction F4) of the second splicing sub-box 32 from the left, the second side b (corresponding to the spray direction F5) of the third splicing sub-box 32 from the left, the first side a (corresponding to the spray direction F6) of the third splicing sub-box 32 from the right, and the second side b (corresponding to the spray direction F7) of the second splicing sub-box 32 from the right. Figure 5 As shown, in the expanded state, one lateral injection hole 33 is arranged on the triangular bottom surface d located at the front side of the third splicing sub-box 32 from the left, and the other lateral injection hole 33 is arranged on the triangular bottom surface d located at the rear side of the third splicing sub-box 32 from the right.

[0042] Furthermore, in order to facilitate wiring, the first side a and the second side b of the triangular prism are provided with wire holes 37, except that the side with the connection hole 36 does not need the wire holes 37. Specifically, the wire holes 37 can be long waist-shaped holes to facilitate the arrangement of multiple sets of leads.

[0043] See also Figure 4In a preferred embodiment, the rotating seat 20 includes a pin shaft 21 and a support plate 22 fixedly sleeved on the pin shaft 21. The bottom end of the pin shaft 21 is rotatably mounted on the base 10, and the top end of the pin shaft 21 extends into the installation sub-box 31. The support plate 22 supports the installation sub-box 31 to ensure that the fireworks box 30 is stably installed while allowing the fireworks box 30 to rotate. In order to prevent the installation sub-box 31 and the pin shaft 21 from being reliably connected and to avoid circumferential relative displacement between the two, a plurality of ridges 211 are arranged at intervals on the outer circumference of the pin shaft 21. The ridges 211 extend along the axial direction of the pin shaft 21 to play a role in circumferential limit or enhance circumferential friction.
