Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
With reference to Fig. 2, preferred embodiment of the present utility model provides a kind of firework external cylinder body, and this firework external cylinder body comprises the cylindrical shell 1 of the cylindrical shape for holding inner barrel and is located at the base 2 of cylindrical shell 1 lower end.Wherein, base 2 comprise round pie body 21 and along the periphery axial tension of body 21 and the circular sidewall 22 formed, the internal face of circular sidewall 22 and the bottom periphery of cylindrical shell 1 are connected.The present embodiment is by arranging the base 2 matched with cylindric cylindrical shell 1, the circular sidewall 22 that base 2 comprises body 21 and formed along the periphery axial tension of body 21, the internal face of circular sidewall 22 and the bottom periphery of cylindrical shell 1 are connected, yellow mud compacting and cylinder inboard wall swelling being coordinated with traditional employing craft or mechanical means makes compared with outer cylinder body, both the Combined machining technique of outer cylinder body had been simplified, and the mass being convenient to base generates, reduce costs, improve working (machining) efficiency, be also convenient to the recycling to outer cylinder body simultaneously.
Alternatively, in the present embodiment, base 2 adopts wood-fibred or pure pulp to make, and overcomes the defect that the outer cylinder body caused at the bottom of the cylinder that traditional yellow mud makes is difficult to recycle.Wherein, in wood-fibred or pure pulp, also other auxiliary materials can be mixed again, such as calcium carbonate and/or starch.
Alternatively, be connected more firm to make base 2 and cylindrical shell 1, and avoid the problem that the base 2 caused because of mismachining tolerance cannot assemble with cylindrical shell 1, with reference to Fig. 3, circular sidewall 22 radially expands gradually near the internal face of top end face, form the first guide section 221, the bottom periphery of cylindrical shell 1 assembles with the inwall of circular sidewall 22 through the first guide section 221, requirement to alignment precision when reducing assembling, and being closely connected of the internal face of circular sidewall 22 and the bottom periphery of cylindrical shell 1 can be realized.
Alternatively, in order to make between cylindrical shell 1 and base 2 be located by connecting more reliable, with reference to Fig. 4, the core of body 21 is forming cylindrical projection 23 towards the side axial tension of circular sidewall 22, the annular groove 24 of the bottom wall body holding cylindrical shell 1 is formed between the periphery of cylindrical projection 23 and the inner headed face of circular sidewall 22, the bottom wall body of cylindrical shell 1 stretches in annular groove 24, to realize the connection of cylindrical shell 1 and base 2.In the present embodiment, base 2 or tight fit connection bonding with the connection cooperation place of cylindrical shell 1.Preferably, tight fit connection is formed between the bottom wall body of cylindrical shell 1 and annular groove 24.More preferably, glue is aided with in connection cooperation place bonding, to strengthen the reliability that base 2 coordinates with cylindrical shell 1.
Preferably, cylindrical projection 23 radially diminishes gradually near the outside wall surface of top end face, forms the second guide section 231.With reference to Fig. 4, the bottom wall body of cylindrical shell 1 stretches in annular groove 24 with coordinating of the second guide section 231 through the first guide section 221, thus reduces the required precision of the processing dimension of cylindrical shell 1 and base 2, and is convenient to assembling.
Alternatively, for the ease of arranging the lead-in wire that cocks off of connection between adjacent firework external cylinder body, with reference to Fig. 5, Fig. 6 and Fig. 8, base 2 is provided with through fairlead 25 vertically, the lower end of body 21 is provided with the housing region 26 of indent, and the radial direction along body 21 on the sidewall of housing region 26 correspondence is provided with the breach 27 being convenient to lead-in wire.The lead-in wire 4 imported from the external world enters housing region 26 through breach 27, and through introducing in the first cavity 7 with the fairlead 25 of housing region 26 conducting; Derived through fairlead 25, housing region 26 and breach 27 successively by lead-in wire 4 again, to be connected in adjacent firework external cylinder body, adopt the cabling mode of the present embodiment, the reliability of lead-in wire cabling can be strengthened, the defects such as the fracture that avoiding goes between occurs in mobile transportation.
According to another aspect of the present utility model, also provide a kind of fireworks, Fig. 7 shows the structural representation of fireworks embodiment one.These fireworks comprise the firework external cylinder body of multiple above-described embodiment, are equipped with inner barrel 3 in each cylindrical shell 1,4 to connect through the sidewall of cylindrical shell 1 between multiple cylindrical shell 1 through going between.
In the present embodiment, the bottom of inner barrel 3 coordinated with the inwall of cylindrical shell 1 every 6 the end of through, and the top of inner barrel 3 coordinates through the inwall of upper cover 5 with cylindrical shell 1.The end, forms the first cavity 7 holding propellant powder between 6 and the end face of base 2, and the end forms the second cavity 8 holding tail medicine between 6 and inner barrel 3, is provided with the 3rd cavity 31 for holding explosive mixture in inner barrel 3.
The course of work of fireworks burning is as follows: burning things which may cause a fire disaster enters the bottom of cylindrical shell 1 from the lead-in wire 4 entering fire, ignite and be positioned at the propellant powder of the first cavity 7, propellant powder burns rapidly, and igniting on the one hand is positioned at the tail medicine of the second cavity 8, on the other hand, during gun propellant combustion, gas moment undergoes rapid expansion produces thrust, inner barrel 3 is under the effect of this thrust, and the inwall along cylindrical shell 1 rushes at sky, now, tail medicine is lighted, and inner barrel afterbody in flight course discharges pearlite and produces fireworks; The moderate length of lead, inner barrel 3 is when highest point, and burning things which may cause a fire disaster introduces the 3rd cavity 31 and the explosive mixture that ignites, and release pearlite also produces beautiful fireworks; Burning things which may cause a fire disaster is introduced in next firework external cylinder body by the lead-in wire 4 for deriving, thus makes the fireworks assembly that is made up of multiple firework external cylinder body, after only needing a burning things which may cause a fire disaster to introduce, can be lighted continuously and automatically, easy to operate and safety.In the present embodiment, for entering fire and the lead-in wire 4 that fires all imports through the side-wall hole of cylindrical shell 1 or derives.
The structural representation of fireworks embodiment two is shown with reference to Fig. 8, Fig. 8.Fireworks embodiment two is substantially identical with the structure of fireworks embodiment one, and difference is, the lead-in wire 4 between two adjacent cylindrical shells 1 is through being located at fairlead 25 on base 2 and breach 27 cabling.The mode of fairlead 25 and breach 27 that base 2 is arranged is with reference to firework external cylinder body embodiment.Adopt this cabling mode, the reliability of lead-in wire cabling can be strengthened, the defects such as the fracture that avoiding goes between occurs in mobile transportation.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
