Embodiment Construction
[0017] Depend on figure 2 It can be seen that the present invention provides a safe sounding fireworks tube, which includes a tube shell (5) and an axial bottom-up tail charge area (1), mud area (4) and explosive charge area (3) in the shell, The sounding fireworks tube also includes a sounder (2) axially penetrating through the mud area, the bottom of the sounder is arranged in the tail charge area and the top is arranged in the explosive area, and the sounder (2) shell radially outside and barrel The mud zone on the radially inner side of the shell (5) is filled with mud, and a protruding ring (21) protrudes outward from the outer circular wall of the housing of the sound generator (2), and a ring (21) is arranged on the axial direction of the fireworks tube. Said raised ring (21) is located in the mud section. And the top of the shell of the sounder (2) is provided with an inclined top surface (22), and an opening (24) is arranged on the top cover plate of the sounder (2)...

The invention provides a safe sound production cylindrical firework. The firework comprises a cylindrical shell, and a tailing explosive region, a mud region and an explosive region which are arrangedin the axis direction of the cylindrical shell from bottom to top. The sound productioncylindrical firework further comprises a sounder with the axial direction penetrating through the mud region, the bottom of the sounder is arranged in the tailing explosive region, and the top of the sounder is arranged in the explosive region; the portion, on the outer side of the radial direction of the shellof the sounder and the inner side of the radial direction of the cylindrical shell, of the mud region is filled with mud, the outer cylindrical wall of the shell of the sounder protrudes outwards toform a convex ring, and the convex ring in the axial direction of the cylindrical firework is located in the mud region. The annular protrusion is arranged on the outer wall of the shell of the sounder, so that the binding force between the sounder and mud becomes larger. Under the blocking effect of the annular protrusion, fire is directly guided in a dry gap in the exterior of the shell of the sounder through the tailing explosive region till improper actions of the explosive region are blocked completely. The sound production cylindrical firework is safer.
Description
technical field [0001] The invention relates to the field of fireworks manufacture, in particular to a safe sounding fireworks tube. Background technique [0002] The sounding fireworks tube contains a plastic sounder (also known as a scream) used for sounding when the fireworks are set off, the lower end of the scream is open, and the upper end is perforated. Such as figure 1 It is a structural schematic diagram of a sounding fireworks tube in the prior art. The sounding fireworks tube includes a tube shell 5 and a tail charge area 1, a mud area 4 and an explosive area 3 axially from bottom to top in the shell, and also includes a sounder 2 axially penetrating through the mud area, and the bottom of the sounder It is arranged in the tail charge area and the top is arranged in the explosive charge area. The radially outer side of the sounder and the radially inner side of the shell (5) are filled with mud, and the sounder shell is cylindrical. Because the cylinder shell i...
