Abstract
The utility model discloses a split-type combination firework which is used for simplifying the production processes of combination fireworks and improving the quality of the fireworks. The split-type combination firework comprises a tube and a base. The base is provided with a boss matched with the inner diameter of the tube, and the bottom of the tube filled with gunpowder is fixed on the boss in a sleeved mode. The boss is provided with a fire igniting hole, one end of the fire igniting hole is communicated with the interior of the tube, and the other end of the fire igniting hole is connected with a firing line arranged on the bottom of the base and is sealed. After the firework is vertically placed, the gunpowder inside the tube is contacted with the firing line through the fire igniting hole, and the firing line is arranged according to the flaming sequence of the tube. A forming method with the firing line directly communicated is adopted, and therefore the flaming rhythm is more stable and acute. A tube body does not need to be provided with holes and to be inserted, the processes for producing the tube are simplified, the strength of the tube is larger, and the flaming process of the firework is safer.
Description
Technical field
The utility model relates to a kind of combined firework, is specifically related to a kind of split type combined firework.
Background technology
Combined firework is the firework product that is formed by a plurality of fireworks tube sub-portfolios, and single bobbin is called one.The conventional combination fireworks assemble by a plurality of papery bobbins are bonding, adopt mudding in the bottom of bobbin, deposit the punching of gunpowder place again in the bottom and insert to draw and pass the fire connection by setting off order between with bobbin.Adopt this production technology when carrying out mudding, pressure is excessive to be supportted bobbin quick-friedly easily, reduces the intensity of bobbin, causes the mass defect of bobbin, and tiny usually crack is difficult for finding, but then has the danger of bombing in the firework display process.In the slotting structural strength of having destroyed bobbin integral body of drawing of the radial direction punching of bobbin, during firework display, the explosion energy part of gunpowder gushes from breach in the bobbin, height and the effect of fireworks lift-off reduce, and punching is inserted, and to draw be operation complicated step comparatively during fireworks are produced, reduce the production efficiency of fireworks, caused standardization or the not high drawback of standard of product.
The utility model content
The defective that technology is various, bobbin intensity is not high at existing combined firework existence, the utility model provides a kind of split type combined firework, adopt complete bobbin structure, do not insert in the bobbin punching and draw, improved the structure of bobbin, simplify the production efficiency of fireworks greatly, improved the effect of firework display.
The utility model adopts following technical scheme to realize: a kind of split type combined firework, comprise bobbin and base, and described base is provided with the boss with bobbin internal diameter coupling, and the bobbin bottom suit behind the filling gunpowder is fixed on the described boss; Described boss is provided with vent, described vent one end is communicated with bobbin inside, and the other end is connected with the lead-in wire that is arranged on the base bottom and seals, after the upright placement of fireworks, gunpowder in the bobbin contacts with lead-in wire by vent, and described lead-in wire is disposed in order according to setting off of bobbin.
Described lead-in wire is complete one, the S-shaped base bottom that is arranged in of the order of setting off along bobbin, and will go between at the vent place is adhesively fixed by glue with base, and by the glue solidifies with the sealing of vent bottom, prevents that the interior gunpowder of bobbin from exposing.
Be interference fit between described bobbin bottom and the boss, and be adhesively fixed by glue.
The utlity model has following beneficial effect:
1) the straight-through molding mode of the lead-in wire jumping formula of inserting of comparing present discontinuous connects, and it is bunch more stable, more accurate to set off joint.
2) the base boss structure is compared the structure of existing bobbin bottom mudding, the active force that the blast of portion of emission officina produces under identical active force is bigger, and this moment, required dose can save 1/3, simultaneously also reduce the active force of propellant powder explosion time to paper web, also reduced the requirement to paper web.
3) solution is simultaneously manually broken the slotting product quality problem that leakage problem and various fitted position relations etc. are brought that suppresses that explodes and produce because of propellant powder that causes that draws of barrel with syringe needle when setting off.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
The decomposing schematic representation of the split type combined firework that Fig. 1 relates to for the utility model.
The front view (base portion broken section) of the split type combined firework that Fig. 2 relates to for the utility model.
Fig. 3 is the upward view of base.
Number in the figure: 1-bobbin, 2-boss, 3-base, 4-lead-in wire, 5-vent.
The specific embodiment
Embodiment
Referring to Fig. 1 to Fig. 3, it is 49 combined firework among the figure, by 7 rows, 7 row bobbin permutation and combination, base 3 is provided with the cylindrical boss 2 of arranging seven row with seven of bobbin 1 internal diameter coupling, bobbin 1 bottom behind the filling gunpowder is sleeved on the boss 2, be interference fit between bobbin 1 bottom and the boss 2, and be adhesively fixed by glue.Be provided with vent 5 at the center of boss 2, vent 5 is the funnel taper, vent 5 upper ends are communicated with bobbin 1 inside, the lower end is connected with the lead-in wire 4 that is arranged on base 3 bottoms and seals, lead-in wire 4 is complete one, along S-shaped base 3 bottoms that are arranged in back and forth of order that bobbin 1 is seted off, will go between at vent 5 places 4 is adhesively fixed by glue with base 3, after the glue solidifies vent 5 bottoms is sealed.
