Specific embodiment
Embodiment 1: referring to attached drawing 1-5, reflect a kind of specific structure of the invention, the float two chamber display shell
Applied to aerial caption-pattern effect is shown, the effect part used includes the lightweight with gas seal property and flame retardant property
Foldable inflating air bag 1, air bag 1 can be used nylon and be applied with neoprene or organosilicon manufacture；Or use poly- phthalein amine fabric
It is made.In order to make air seal and fire-retardant, the medial surface of air bag 1 is coated with polychlorobutadiene.Air bag 1 is equipped with inflating port 3, inflating port
Air bag 1 around 3 should do consolidation process.
The effect part further includes the gas making disk 9 in cylindrical body, and the bottom face 10 of the gas making disk 9 seals, in bottom face 10
The heart is equipped with fairlead 11, and the surrounding side wall and top end face of gas making disk 9 gather a large amount of ventilating slits uniformly to meet quick outlet
It is required that the grid body as shown in this example.
The sodium azide 12 of stacking several layers disc-shaped, disc-shaped sodium azide 12 are equipped with central through hole, institute in gas making disk 9
The burning firework medicament 13 of filler particles shape in central through hole is stated, fiery lead 6 is passed and passes through the fairlead 11 insertion burning pyrotechnics
In medicament 13；Described 13 need of burning firework medicament can be passed fiery lead and be lighted, and ignition temperature is not less than 300 DEG C.
In this example, the burning firework medicament is made of the component of following weight ratio: 30~40 parts of titanium valve (combustible), potassium hyperchlorate 60
Appropriate pyrotechnic composition adhesive (such as nitrocellulose solution, resin, clear is added in~70 parts (oxide), 4~8 parts of charcoal powders (detonator)
Paint, acetone etc.) it is granulated, is sieved, is drying to obtain.
The gas gathering mask 5 of 9 housing of gas making disk sealing, gas gathering mask 5 are equipped with gas outlet 4, and the connection of inflating port 3 of the air bag 1 is simultaneously
Affixed gas outlet 4, it is described affixed as threaded connection is aided with glue bonding again.
Multiple subtitle pipes 8 are fixed on 1 outer surface of air bag according to the shape (being " ten " word in this example) of preset shape,
In this example, 1 surface of air bag is equipped with the bag body 7 of fixed subtitle pipe 8.Subtitle pipe 8 need to be only inserted into bag body 7 to be convenient to admittedly
Dingan County's dress, can also be aided with glue or adhesive tape bonding.It is concatenated between each subtitle pipe 8 with rapid lead wire 2, rapid lead wire 2 in this example
Two strands of leads of right-angled intersection make to pass fiery connection processing.The connection delay lead 16 of rapid lead wire 2, delay lead 16 and biography fire draw
Line 6 is lighted via overshoot lead wire 15 by the quick-fried medicine 19 of opening of display shell, and overshoot lead wire 15 is arranged at the center of partition 18.
Display shell includes the spherical shell 14 that two valve hemispheres are combined into, and 14 inner route clapboard 18 of spherical shell is divided into out shot room and effect
Room opens quick-fried indoor set filler 17 and opens quick-fried medicine 19, opens quick-fried medicine 19 equipped with ignition fuse 20 and its shield skirt 21；Air bag 1 and
Subtitle pipe 8 etc. collects agglomerating, is placed in the inner cavity of effect room together with gas making disk 9, gas gathering mask 5 etc., and with filler 17 build it is tight simultaneously
Adjust body center of gravity.The filler such as husk, cotton seed hulls or perlite particle etc..After being collected due to folding, the effect part
Volume is still larger, so it is used to load the specification of the display shell of the effect part to be advisable not less than 6 inches.
After display shell is emitted in the air, ignited out by the ignition fuse 20 that display shell propellant powder (not shown) is ignited quick-fried
Medicine 19, spherical shell 14 blow effect part of dishing out, and are opened the overshoot lead wire 15 that quick-fried medicine 19 ignites and light the fiery lead 6 of biography, pass fiery 6 points of lead
The burning firework medicament 13 in 12 central through hole of sodium azide is fired, the high temperature that firework medicament 13 burns makes sodium azide 12 heated
It decomposes, discharges a large amount of nitrogen, nitrogen enters gas gathering mask 5 by the ventilating slit of 9 surrounding of gas making disk, then passes through gas outlet 4, inflation
Mouthfuls 3 are filled with the air bag 1, and for air bag 1 after firing about in the time of a few tens of milliseconds full of expanding rapidly after hot nitrogen, actual measurement can
Steadily high-altitude floating is kept in 30 minutes, as the platform for showing caption pattern firework moulding.
In this example, the gas gathering mask 5 and its gas making disk 9 are made the clump weight for constituting air bag 1 of steel.So that air bag 1
After expansion expansion, its posture meets the requirements under the action of counterweight.Quick-fried medicine 19 is opened also to exist by delay lead 16, rapid lead wire 2
Subtitle pipe 8 is lighted after setting delay, subtitle pipe 8 forms the aerial effect picture of scheduled " ten " word after being ignited.
It in this example, is installed in the fairlead 11 after passing fiery lead 6, the hole around lead is intracavitary to fill sealing compound, institute
It states sealing compound to be made of the component of following weight ratio: 8 parts of potassium nitrate, 10 parts of active carbon, 1 part of sulphur, 1 part of charcoal powder.Seal medicine
The solid remains that will form fine and close expansion after agent burning block fairlead 11 to realize that sealing avoids gas leakage, further extend drift
The floating time.
Example 2: referring to attached drawing 6, difference from example 1 is that, luminescent characters " happiness " is arranged in 201 surface of air bag.Not yet
There are installing subtitle pipe and its lead to pass fiery structure etc..Remaining is same as Example 1.
The luminescent characters can be by the way of being coated with fluorescent characters, or uses battery powered LED luminescent characters.
In other embodiments, the air bag can be made as various moulding, such as animal, be aided with fluorescence, illumination or subtitle
The illuminators such as pipe are in its moulding of night aerial display.
Above-mentioned implementation is merely to clearly illustrate technical solution of the present invention, and should not be understood as to the present invention
Make any restrictions.The present invention has well known a variety of substitutions or deformation in the art, is not departing from essence of the invention
Under the premise of meaning, protection scope of the present invention is each fallen within.
