Embodiment 1

[0026] Double-ring firecracker continuous discharger, the structure is shown in Figure 14, using 4 set screws as the link screw 4, the same diameter of the disc base 1, the upper porous disc surface 3 and the lower porous disc surface 2 through the screw link hole 6. After linking, make the disc base 1, the upper porous disc surface 3 and the lower porous disc surface 2 parallel to each other, and the centers of the holes on the upper and lower porous disc surfaces are on the same axis. Both the upper and lower layers of the porous disk are provided with a central circular hole and 12 circular holes distributed at equal angles around it. The distance between the lower porous disc surface 2 and the disc base 1 is controlled to be 20mm-25mm, and the distance between the upper porous disc surface 3 and the disc base 1 can be adjusted freely according to the length of the double-shot firecrackers. To ensure safety, double-shot firecrackers are generally required The main body is 10mm-...

Embodiment 2

[0029] The double-shot firecracker continuous discharger is different from the first embodiment in that there is no inclination adjustment screw under the disc base 1, and this design is suitable for setting off firecrackers vertically.

Embodiment 3

[0031]The difference between the double-shot firecracker continuous discharger and the first embodiment is that the diameter of the disc base 1 and the lower porous disc surface 2 and the upper porous disc surface 3 are slightly different. The diameter of the disc base 1 can be designed to be the largest, the diameter of the lower porous disc surface 2 is second, and the diameter of the upper porous disc surface 3 is the smallest, which is convenient to increase the stability of the discharger.

Abstract

The invention discloses a double-bang firecracker continuously setting-off device which consists of a disc pedestal, a lower layer porous disc face, an upper layer porous disc face and a linkage screw bolt. The linkage screw bolt connects the lower layer porous disc face and the upper layer porous disc face with the disc pedestal. The circular hole circle centers of the lower layer porous disc face and the upper layer porous disc face are arranged in the same axial line. The device can be used for setting off double-bang firecracker fast; the firecracker can be placed in the holes of two layers of porous disc faces on the disc pedestal to ensure that the firecracker can not fall due to the factors of improper placement, vibration, strong wind and the like, and the safety of setting-off posture is ensured; and the setting-off angle of the device is adjustable, thereby ensuring the safety at utmost.

Description

Technical field [0001] The invention belongs to the field of mechanical equipment, and specifically relates to a double-ring firecracker continuous discharger, in particular to a device suitable for setting off two-ring firecrackers conveniently, quickly and safely in environments with strong winds, uneven ground, and many people on the ground. Continuous discharger with adjustable firing angle. Background technique [0002] There is a tradition of setting off firecrackers in our country during major festivals. Now the size and power of aerial firecrackers are getting bigger and bigger. Some double-shot firecrackers have a diameter of 50mm, a length of 20cm, and a height of more than 50m. The traditional way of setting off is already very unsafe. It is precisely because of the improper way of setting off or the lack of a special safety setting device that the phenomenon of injuries caused by setting off firecrackers has been reported frequently, which is contrary to the original ...
