[0002] Traditionally, fireworks shows are carried out by products ignited by electronic igniters, that is, the electronic igniters are in contact with the leads of the fireworks products for ignition. In this process, the cable must be connected to the igniter or ignition system to ignite.

The numbers of the touch pin 2 and the connecting piece 4 are both two and correspond one by one. The pin housing 5 is connected to the bottom of the track 1 by bolts, and the pin housing cover 6 is connected to the bottom of the pin housing 5 by bolts. The two connecting pieces 4 are spaced between the pin housing 5 and the pin housing cover 6 and are used to connect the positive and negative poles of an external power supply through cable wires respectively. The two touch pins 2 are arranged on the pin housing 5, and the first end of the touch pin 2 is located above the track 1. The second end of the touch pin 2 is connected to the corresponding connecting piece 4 through a spring 3. The ignition device 10 is detachably arranged on the top of the track 1, and the electric igniter 8 is arranged on the ignition device 10 and is electrically connected to the two touch pins 2. Among them, the track 1, the pin housing 5, and the pin housing cover 6 are made of insulating materials such as plastic, rubber, or ceramic, and the touch pin 2, the connecting piece 4, and the spring 3 are made of conductive materials, such as copper alloy, aluminum alloy, etc.

[0049] In a specific application process, the cables between the two connecting pieces 4 and the external power supply can be connected in advance. During the fireworks show, the ignition device 10 only needs to be assembled on the track 1 and brought into contact with the contact pin 2 to quickly complete the circuit assembly of the ignition system. There is no need to temporarily connect the cables before the fireworks show, making the installation of the fireworks display quick and simple, and having high practicality.

[0050] In this embodiment, the position on the track 1 corresponding to the ignition component has a mounting groove, and the mounting groove vertically penetrates the track 1, and the top of the pin housing 5 has a protruding structure adapted to the mounting groove. During assembly, after the protruding structure at the top of the pin housing 5 is embedded in the mounting groove, it is fixedly connected to the track 1 by bolts, and the top plane of the protruding structure is lower than or flush with the top plane of the track 1. The top of the protruding structure has two spaced grooves, and the two connecting pieces 4 are respectively at the bottom of the two grooves. The second end of the contact pin 2 is located in the corresponding groove and is connected to the spring 3. The first end of the first contact pin 2 extends upward out of the groove and is higher than the top plane of the track 1. Preferably, the first end of the contact pin 2 is a rounded structure.

[0051] Specifically, there are two pin channels corresponding to the connecting piece 4 between the pin shell 5 and the pin shell cover 6. The first end of the connecting piece 4 is located between the pin shell 5 and the pin shell cover 6 and is connected to the spring 3. The second end of the connecting piece 4 extends to the outside of the pin shell 5 and the pin shell cover 6 through the corresponding pin channel to connect the electrodes of the external power supply through a cable.

[0052] In the specific implementation process, the second end of the contact pin 2 has a first embedding groove, and the first end of the connecting piece 4 has a second embedding groove. During assembly. The first end of the spring 3 is embedded in the first embedding groove corresponding to the contact pin 2 and connected to the contact pin 2, and the second end of the spring 3 is embedded in the second embedding groove corresponding to the connecting piece 4 and connected to the connecting piece 4. It is worth noting that in the specific application process, the first embedding groove and / or the second embedding groove may not be provided, and the spring 3 connecting piece 4 is directly provided at the end of the spring 3 and assembled by welding or bolting.

[0053] refer to Figures 4 to 6 , a PCB board 7 (i.e., printed circuit board) is fixedly provided on the ignition device 10, a contact plate 9 corresponding to the two contact pins 2 is welded at the bottom of the PCB board 7, an electric igniter 8 is welded on the top of the PCB board 7, and the electric igniter 8 is electrically connected to the two contact plates 9. When the ignition device 10 is assembled on the track 1, the two contact plates 9 are respectively in contact with the two contact pins 2, so that the circuit connection between the electric igniter 8 and the external power supply can be realized. Among them, the electric ignition head adopts a conventional resistance type ignition head.

[0054] In the specific implementation process, the ignition device 10 as a whole is a cylindrical structure with openings at both ends, and a detachable cover plate is assembled at its bottom end through a connecting structure such as bolts or buckles. The PCB board 7 is clamped between the bottom end of the ignition device 10 and the cover plate. Preferably, flanges are provided on both sides of the track 1 along the width direction, so that card slots are formed on both sides of the track 1. A skirt is provided on the outer wall of the bottom of the ignition device 10, and the bottom edge contour of the skirt is a chamfered corner structure. During assembly, the ignition device 10 is slid into the track 1 from one end of the track 1, and at the same time, the skirt is respectively snapped into the corresponding card slots on both sides of the track 1 along the width direction of the track 1. When the two contact plates 9 are respectively in contact connection with the two contact pins 2, it means that the ignition device 10 is assembled in place, that is Figure 7 as shown. Then the fireworks cartridge 11 is assembled on the ignition device 10, the switch of the external power supply is turned on, the electric igniter 8 is powered on and heated, and the fuse of the fireworks cartridge 11 is ignited, and the fireworks can be launched.

[0055] Further preferably, internal threads can be provided on the inner wall of the barrel of the ignition device 10, and at the same time, matching external threads can be provided on the outer wall of the fireworks cartridge 11, and then the fireworks cartridge 11 is threadedly connected to the ignition device 10 to ensure the stability of the installation of the fireworks cartridge.

[0056] The card slots on the track 1 can only limit the ignition device 10 in the width direction of the track 1. Therefore, as a preferred implementation method, one side or both sides of the skirt along the length direction of the track 1 are also connected to the track 1 through a limiting mechanism to limit the ignition device 10 in the length direction and height direction of the track 1 to improve the safety and reliability of the fireworks display. Refer to Figure 8 , the limiting mechanism can adopt the first bolt 12 and the second bolt 13 threadedly connected to the track 1. Fixed bolt recesses 15 for abutting against the first bolt 12 and the second bolt 13 are respectively provided on both sides of the skirt along the length direction of the track 1 to limit the ignition device 10 in the length direction of the track 1. Among them, the first bolt 12 and / or the second bolt 13 press on the top of the skirt to limit the ignition device 10 in the height direction of the track 1. Of course, in specific applications, it is not limited to using the first bolt 12 and the second bolt 13 for limiting. For example, a through hole can be directly opened on the skirt, and a threaded hole coaxial with the through hole can be opened on the track 1, and the skirt and the track 1 can be connected and fixed through a set of bolts, and the ignition device 10 can also be limited.

[0057] In the specific implementation process, when the number of ignition systems is more than two, the bases of the tracks 1 of the shared-track quick-setting fireworks ignition systems share the same track 1, and each ignition system is distributed at intervals along the length direction of the track 1, for example Figure 9 , Figure 10 as shown, so that the ignition system in this embodiment has high flexibility and modularity.

Among them, the orbital bracket 14 can be Figure 11 the plastic bracket shown, or can also be Figure 12 the metal bracket shown.
