The launch tube provided by the utility model is detachably connected to the launch base assembly, allowing for the arrangement and replacement of launch tubes according to desired display needs, creating different types of fireworks and enabling flexible and varied display styles.
[0006] Optionally, the axial positioning structure includes a first limiting structure provided on the inner peripheral wall of the mounting seat and a second limiting structure provided on the outer peripheral wall of the launch tube, and the first limiting structure and the second limiting structure are axially abutted against each other.
[0007] In the above scheme, the axial positioning of the mounting seat and the launch tube is achieved by the rotational engagement of the first limiting structure and the second limiting structure. The structure is simple and the disassembly and assembly of the launch tube is also relatively simple.
[0008] Optionally, the number of the first limiting structure and the number of the second limiting structure are both one; or,
[0009] The number of the first limiting structures and / or the second limiting structures is at least two, and both are distributed at intervals along the axial direction of the launch tube. The first limiting structures and the second limiting structures are alternately arranged in the axial direction of the launch tube.
[0010] In the above scheme, when the number of the first limiting structure and / or the second limiting structure is at least two, the axial positioning structure is used to limit the launch tube and the mounting seat in two axial directions, which can prevent the launch tube from bouncing in the mounting seat during vibration, and the connection between the launch tube and the mounting seat is also more stable.
[0011] Optionally, the first limiting structure includes a plurality of first limiting protrusions arranged at circumferential intervals, and the second limiting structure includes a plurality of second limiting protrusions arranged at circumferential intervals, the circumferential size of the second limiting protrusions being smaller than the circumferential spacing size between two adjacent first limiting protrusions, and the first limiting protrusions and the second limiting protrusions abut against each other in the axial direction of the launch tube.

[0013] Optionally, the launch seat assembly further includes a pin structure, which includes a pin seat, a pin part, and an elastic member connecting the pin seat and the pin part. The pin seat is fixed to the mounting seat, and the pin part is axially abutted against the end plate of the launch tube.

Electrode excitation also enables remote terminal control of the fireworks display, replacing the traditional wire-fired fireworks display, resulting in a high degree of electronicization. The circuit board is secured to the mounting base using a nut and external threads on the pin holder.

The launching tube is detachably connected to the launching base assembly, so the launching tube can be arranged and replaced according to the firing requirements to achieve flexible and changeable firing forms. The launching base assembly can be reused.

[0050] Fireworks and other products consist of multiple launch tubes arranged in an array, each containing a firework shell. The shell can be detonated using either a gunpowder fuse or an electronic fuse. Each launch tube is typically fixed to a corresponding mounting position on a launch pad. Therefore, after design and production are complete, the launch tubes cannot be replaced, preventing the ability to quickly implement flexible and varied firing patterns.
[0051] To address the aforementioned technical issues, the present invention proposes a firework launch assembly 100, a firework launch device 1000, and a firework display system. The launch tube 20 in the firework launch assembly 100 is detachably connected to the launch base assembly 10. Specifically, the launch tube 20 and the launch base assembly 10 are rotatably engaged, and a spring pin structure 12 at the bottom of the mounting base 11 abuts the launch tube 20, providing a pre-tightening force for the launch tube 20 and improving the stability of the connection between the launch tube 20 and the launch base assembly 10. The launch tube 20 in the present invention can be quickly replaced, allowing for quick changes in the fireworks display effect. This significantly increases the number of fireworks display options while also reducing the demands on the workplace and personnel.
[0052] The firework launching assembly 100 provided in an embodiment of the present invention is now described.
[0053] Please also refer to Figures 1 to 5 The firework launching assembly 100 includes a launching base assembly 10 and a launching tube 20 . The launching tube 20 is detachably connected to the launching base assembly 10 .
[0054] The launch tube 20 is tubular, and the axial direction of the launch tube 20 is its length direction. For the convenience of description, the axial direction of the launch tube 20 and the direction parallel to the axial direction are referred to as the axial direction. Fireworks that can be detonated are arranged inside the launch tube 20.
[0055] The launching base assembly 10 includes a mounting base 11, which has an inner cavity. At least a portion of the launching tube 20 is located in the inner cavity of the mounting base 11, and an axial positioning structure 30 is provided between the mounting base 11 and the launching tube 20. The mounting base 11 and the launching tube 20 are rotationally connected at least through the axial positioning structure 30, so that the launching tube 20 and the mounting base 11 limit each other in the axial direction.
[0056] When installing the launch tube 20, the launch tube 20 is inserted into the mounting seat 11 and rotated so that the launch tube 20 and the mounting seat 11 are locked together by the axial positioning structure 30. When removing the launch tube 20, the launch tube 20 is rotated to unlock the axial positioning structure 30, and then the launch tube 20 is taken out.
[0057] The fireworks launching assembly 100 in the above embodiment includes a launching base assembly 10 and a launching tube 20, and the launching tube 20 is arranged in the mounting base 11. The mounting base 11 and the launching tube 20 are rotated and clamped by the axial positioning structure 30 to achieve axial positioning of the mounting base 11 and the launching tube 20, so that the launching tube 20 is stably installed on the mounting base 11. When disassembling the launching tube 20, the launching tube 20 can be removed by rotating the launching tube 20. The launching tube 20 provided by the utility model is detachably connected to the launching base assembly 10, and the launching tube 20 can be arranged and replaced according to the demand for firing, forming different types of fireworks, realizing flexible and changeable firing forms, and the launching base assembly 10 can be reused. Compared with traditional fireworks, there is no need to arrange a large number of fireworks gift boxes in advance, which greatly reduces the requirements for the firing site.
[0058] In some embodiments of the present invention, please refer to Figure 2 and Figure 5 The axial positioning structure 30 includes a first limiting structure 1111 disposed on the inner circumferential wall of the mounting seat 11 and a second limiting structure 21 disposed on the outer circumferential wall of the launch tube 20. The first limiting structure 1111 and the second limiting structure 21 are axially abutted. When the launch tube 20 is installed, the launch tube 20 gradually extends into the mounting seat 11, and the second limiting structure 21 gradually passes over the first limiting structure 1111. The launch tube 20 is then rotated, causing the first limiting structure 1111 and the second limiting structure 21 to engage with each other.
[0059] The axial positioning of the mounting seat 11 and the launch tube 20 is achieved by the rotational engagement of the first limiting structure 1111 and the second limiting structure 21 . The structure is simple and the assembly and disassembly of the launch tube 20 is also relatively simple.
[0060] In some embodiments, the number of the first limiting structure 1111 and the second limiting structure 21 are both one. When the launch tube 20 is installed on the mounting base 11, the first limiting structure 1111 and the second limiting structure 21 abut against each other in the axial direction, limiting one of the axial directions of the launch base assembly 10 and the mounting base 11. When installing the launch tube 20, the second limiting structure 21 is aligned with the gap between two adjacent first limiting structures 1111, the launch tube 20 is inserted, and after the second limiting structure 21 passes over the first limiting structure 1111, the launch tube 20 is rotated, and the first limiting structure 1111 and the second limiting structure 21 abut against each other. In this embodiment, the number of the first limiting structure 1111 and the second limiting structure 21 are both one, and the structure of the launch tube 20 and the mounting base 11 is relatively simple.
[0061] In some embodiments, see Figure 2 and Figure 5The number of the first limiting structures 1111 and / or the second limiting structures 21 is at least two, and they are spaced apart along the axial direction of the launch tube 20. The first limiting structures 1111 and the second limiting structures 21 are alternately arranged in the axial direction of the launch tube 20. After the launch tube 20 is mounted on the mounting seat 11, the first limiting structure 1111 is inserted between the two second limiting structures 21, or the second limiting structure 21 is inserted between the two first limiting structures 1111, and the axial fixing structure 30 is used to achieve axial fixation of the launch tube 20 and the mounting seat 11.
[0062] The axial positioning structure 30 is used to limit the launch tube 20 and the mounting seat 11 in two axial directions, which can prevent the launch tube 20 from bouncing in the mounting seat 11 during vibration, and the connection between the launch tube 20 and the mounting seat 11 is also more stable.
[0063] Optionally, the distance between two adjacent first limiting structures 1111 matches the axial dimension of the second limiting structure 21 , and the distance between two adjacent second limiting structures 21 matches the axial dimension of the first limiting structure 1111 .
[0064] Optionally, there is one first limiting structure 1111 and two second limiting structures 21 , and the first limiting structure 1111 is used to be inserted between the two second limiting structures 21 to achieve axial fixation of the launch tube 20 and the mounting seat 11 .
[0065] Optionally, there are two first limiting structures 1111 and one second limiting structure 21 , and the second limiting structure 21 is used to be inserted between the two first limiting structures 1111 to achieve axial fixation of the launch tube 20 and the mounting seat 11 .
[0066] Optionally, there are multiple first limiting structures 1111 and second limiting structures 21. After the launch tube 20 is installed, the first limiting structures 1111 and the second limiting structures 21 are alternately distributed in the axial direction to achieve axial fixation of the launch tube 20 and the mounting seat 11.
[0067] Optionally, the first limiting structure 1111 and the second limiting structure 21 have the same size in the axial direction, and the gap between two adjacent first limiting structures 1111 and the spacing between two adjacent second limiting structures 21 are also the same, which facilitates the design and processing of the launching base assembly 10 and the mounting base 11.
[0068] In some embodiments, see Figure 2 and Figure 5The first limiting structure 1111 includes a plurality of first limiting protrusions 11111 spaced circumferentially, and the second limiting structure 21 includes a plurality of second limiting protrusions 211 spaced circumferentially. The circumferential dimension of the second limiting protrusions 211 is smaller than the circumferential spacing between two adjacent first limiting protrusions 211. The first limiting protrusions 11111 and the second limiting protrusions 211 abut against each other in the axial direction of the launch tube 20. When the launch tube 20 is installed inside the mounting seat 11, at least a portion of the inner circumferential wall of the mounting seat 11 and at least a portion of the outer circumferential wall of the launch tube 20 are adjacent to each other. The axial positioning structure 30 is disposed on the inner circumferential wall of the mounting seat 11 and the outer circumferential wall of the launch tube 20. The plurality of first limiting protrusions 11111 are sequentially spaced along the inner circumferential wall of the mounting seat 11, and the plurality of second limiting protrusions 211 are sequentially spaced along the outer circumferential wall of the launch tube 20. When installing the launch tube 20, the second limiting structure 21 on the launch tube 20 is aligned with the gap between two adjacent first limiting structures 1111. The launch tube 20 is axially inserted into the mounting seat 11. After the second limiting structure 21 passes over the first limiting structure 1111, the launch tube 20 is rotated so that the first limiting structure 1111 and the second limiting structure 21 abut against each other, forming axial limitation of the launch tube 20 and the mounting seat 11 assembly.
[0069] The first limiting structure 1111 and the second limiting structure 21 are respectively arranged on the inner circumferential wall of the mounting seat 11 and the outer circumferential wall of the launch tube 20. The first limiting structure 1111 includes a plurality of first limiting protrusions 11111 arranged at circumferential intervals, and the second limiting structure 21 includes a plurality of second limiting protrusions 211 arranged at circumferential intervals, so that the second limiting protrusion 211 can pass through the gap between the two first limiting protrusions 11111, thereby realizing the mutual abutment between the first limiting structure 1111 and the second limiting structure 21 in the axial direction, thereby realizing the axial limitation of the launch tube 20 and the mounting seat 11.
[0070] In some embodiments, the number of the first limiting protrusions 11111 and the second limiting protrusions 211 is two, three, four, etc., and the specific number is not limited here.
[0071] In some embodiments of the present invention, please refer to Figure 1 and Figure 4The launch base assembly 10 also includes a pin structure 12, which includes a pin seat 122, a pin portion 121, and an elastic member connecting the pin seat 122 and the pin portion 121. The pin seat 122 is fixedly connected to the mounting base 11, and the pin portion 121 is axially abutted against the end plate of the launch tube 20. When the pin portion 121 is subjected to pressure, the elastic member is deformed, and the restoring force of the elastic member causes the pin portion 121 to generate pressure on the pressure object. The pin structure 12 is fixedly connected to the mounting base 11, and the pin portion 121 is located at the bottom of the mounting base 11 and is used to axially abut against the launch tube 20. When the launch tube 20 is installed on the mounting base 11, the launch tube 20 and the pin portion 121 abut each other, the elastic member is deformed, and the pin portion 121 exerts a reverse thrust on the launch tube 20. Through the cooperation between the axial positioning structure 30 and the elastic pin structure 12 , the launch tube 20 can be made more stable in the axial direction, providing a pre-tightening force for the launch tube 20 .
[0072] By arranging the elastic pin structure 12 on the mounting seat, the elastic pin portion 121 of the elastic pin structure 12 abuts against the launch tube 20, which can provide a pre-tightening force for the launch tube 20 and prevent the launch tube 20 from shaking in the axial direction.
[0073] In some embodiments of the present invention, the outer periphery of the spring pin seat 122 has external threads, and the mounting base 11 defines a threaded hole 1112, with the spring pin seat 122 being threadedly connected to the threaded hole 1112. When installing the spring pin structure 12, the spring pin structure 12 is aligned with the threaded hole 1112 and rotated to secure the spring pin structure 12 to the mounting base 11, with the spring pin portion 121 located within the mounting base 11.
[0074] The external thread on the outer periphery of the elastic pin seat 122 is threadedly connected to the threaded hole of the mounting seat 11, so that the elastic pin structure 12 can be fixed on the mounting seat 11 through its own thread without the need for other fixing parts or connecting parts.
[0075] In some embodiments of the present invention, please refer to Figure 4 and Figure 5The launch base assembly 10 also includes a nut 14 and a circuit board 13 disposed outside the mounting base 11. The circuit board 13 has an electrode 131 that passes through the mounting base 11 and is connected to the launch tube 20. The circuit board 13 defines a first connection hole 132 for the pin seat 122 to pass through. The nut 14 is threadedly connected to the pin seat 122, pressing the circuit board 13 against the mounting base 11. The pin structure 12 passes through the first connection hole 132 of the circuit board 13 and is fixed to the mounting base 11. The nut 14 cooperates with the external threads on the pin seat 122 to secure the circuit board 13 to the mounting base 11. The circuit board 13 is provided with an electrode 131. After receiving a launch signal, the electrode 131 discharges to ignite the fuse, detonating the fireworks shell in the launch tube 20. One end of the electrode 131 is electrically and fixedly connected to the circuit board 13, and the other end of the electrode 131 passes through the mounting base 11 and extends into the interior of the mounting base 11.
[0076] By configuring the circuit board 13, the fireworks launching assembly 100 can detonate the fireworks shells by means of excitation by the electrode 131. Therefore, the customized needs of the fireworks firing effect (various texts, symbols, or patterns, etc.) can be met. At the same time, the use of the electrode 131 excitation method can realize remote terminal control of the firing process, replacing the traditional fuse firing of fireworks, and having a high degree of electronicization. By configuring the nut 14 and utilizing the external thread on the pin holder 122, the circuit board 13 is fixed to the mounting base 11. When fixing the circuit board 13, there is no need to re-open the connection holes for connecting with the screws on the circuit board 13 and the mounting base 11. The structure of the circuit board 13 and the mounting base 11 is relatively simple.
[0077] In some embodiments, the electrode 131 is divided into a positive electrode and a negative electrode. The positive electrode and the negative electrode discharge to ignite the fuse, thereby detonating the fireworks.
[0078] Optionally, the number of the positive electrode is one, the number of the negative electrodes is two, and the two negative electrodes are arranged on opposite sides of the positive electrode to enhance the discharge effect.
[0079] Optionally, the number of nuts 14 and pin structures 12 is the same, and the number of nuts 14 and pin structures 12 is at least two, such as two, three, four, etc., which can improve the stability of the launch tube 20 and the stability of the connection between the mounting base 11 and the circuit board 13.
