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 and Fig. 3, preferred embodiment of the present utility model provides a kind of fireworks inner tank body, this fireworks inner tank body 2 comprises: for holding the cylindrical shell 24 of the cylindrical shape of explosive mixture and being located at the base 21 of cylindrical shell 24 lower end, the upper end of cylindrical shell 24 is provided with sealing 23; Base 21 comprises: the circular sidewall 212 that body 211 and the periphery axial tension along body 211 are formed, and the internal face of circular sidewall 212 and the bottom periphery of cylindrical shell 24 are connected, and body 211 is provided with fairlead 213.The present embodiment is by arranging the base 21 matched with cylindrical shell 24, the circular sidewall 212 that base 21 comprises body 211 and formed along the periphery axial tension of body 211, the internal face of circular sidewall 212 and the bottom periphery of cylindrical shell 24 are connected, yellow mud compacting and cylinder inboard wall being coordinated with traditional employing craft or mechanical means is formed compared with lower seal, both the processing technology of fireworks inner tank body 2 had been simplified, and the mass being convenient to base 21 generates, reduce costs, improve working (machining) efficiency, the structure be simultaneously connected through the internal face of circular sidewall 212 and the bottom periphery of cylindrical shell 24, effectively ensure that the connection reliability of base 21 and cylindrical shell 24.In the present embodiment, explosive mixture 25 is placed in region between the inherent base 21 of cylindrical shell 24 and upper sealing 23, base 21 accommodates tail medicine 28 in the bottom notch portion 214 of body 211, and lead 26 runs through body 211 to connect the cavity placing explosive mixture 25 and the region holding tail medicine 28.
Alternatively, in the present embodiment, base 21 adopts wood-fibred or pure pulp to make, overcome fireworks inner tank body 2 that lower seal that traditional yellow mud makes causes aloft explosion time produce yellow mud block and easily hurt sb.'s feelings and damage the defect of thing.Wherein, in wood-fibred or pure pulp, also other auxiliary materials can be mixed again, such as calcium carbonate and/or starch.
Alternatively, in order to make base 21 and cylindrical shell 24 be connected more firm, avoid the problem that the base 21 caused because of mismachining tolerance cannot assemble with cylindrical shell 24, circular sidewall 212 radially extends out gradually near the internal face of top end face.The bottom periphery of cylindrical shell 24 because there being the guiding of the internal face that circular sidewall 212 extends out, the requirement to alignment precision when reducing assembling, and the compact siro spinning technology of the internal face of circular sidewall 212 and the bottom periphery of cylindrical shell 24 can be realized.
Alternatively, for the ease of assembling, circular sidewall 212 is circumferentially interval with multiple breach, makes circular sidewall 212 have certain elastic deformation, to facilitate coordinating of its bottom periphery with cylindrical shell 24.In the present embodiment, base 21 or tight fit connection bonding with the connection cooperation place of cylindrical shell 24.Preferably, tight fit connection is formed between the bottom periphery of cylindrical shell 24 and the internal face of circular sidewall 212.More preferably, glue is aided with in connection cooperation place bonding, to strengthen the reliability that base 21 coordinates with cylindrical shell 24.
Alternatively, with reference to Fig. 3, the bottom of base 21 is provided with the recessed depressed part 214 to cylindrical shell 24, and depressed part 214 is for holding tail medicine.
Certainly, it will be understood by those skilled in the art that the upper hermetically-sealed construction matched in the upper end of the cylindrical shell 24 in the present embodiment can adopt traditional solid flashing composition, also can change, but still within the protection domain of this patent.Fig. 4 shows the structural representation of another embodiment fireworks inner tank body of the utility model, and in this embodiment, the upper end of cylindrical shell 24 is used gland 22 instead and substituted traditional upper sealing 23, is connected through the periphery of gland 22 and the top inner headed face of cylindrical shell 24.
With reference to Fig. 5, alternatively, gland 22 is in round pie, and comprise stitching surface and the upper surface relative with stitching surface, the periphery of stitching surface is provided with arc angling 221, to facilitate coordinating of gland 22 and cylindrical shell 24.Preferably, gland 22 pure paper oar or wood-fibred compacting form, and also can mix calcium carbonate, starch etc. again in paper oar or wood-fibred and mix, avoid the contamination by dust of fireworks inner tank body 2 explosion time.
With reference to Fig. 6, alternatively, the upper surface of gland 22A is provided with the groove 222 of indent, like this, on the one hand can material-saving, alleviate the weight of gland, can produce distortion in process of press on the other hand, be conducive to being pressed in cylindrical shell 24.Preferably, multiple groove can be circumferentially interval with at the external cylindrical surface of gland.More preferably, multiple groove is arranged along uniform intervals in the circumference of gland.Like this, both facilitate gland to load cylindrical shell 24 smoothly, the swelling effect between gland and cylindrical shell 24 internal face can have been ensured again simultaneously, to reach better sealing effectiveness, thus improve working (machining) efficiency and the crudy of fireworks inner tank body.
According to another aspect of the present utility model, additionally provide a kind of fireworks embodiment, with reference to Fig. 7, comprise firework external cylinder body 1, and apply the fireworks inner tank body 2 of above-mentioned any embodiment, fireworks inner tank body 2 is located in firework external cylinder body 1.The bottom of fireworks inner tank body 2 coordinated with the inwall of firework external cylinder body 1 every 3 the end of through, and the top of fireworks inner tank body 2 coordinates through the inwall of upper cover 7 with firework external cylinder body 1.Fireworks inner tank body 2 comprises cylindric cylindrical shell 24.The end, forms the first cavity holding tail medicine 28 between 3 and fireworks inner tank body 2, the end, forms every the bottom of 3 and firework external cylinder body 1 the second cavity holding propellant powder 4, is provided with and extends the outside lead 26 entering fire lead-in wire 5 and fire lead-in wire 6 and linking the first cavity and the second cavity in the second cavity.
The course of work of fireworks burning is as follows: burning things which may cause a fire disaster is from the bottom entered fire lead-in wire 5 and enter firework external cylinder body 1, and ignite the propellant powder 4 be positioned at bottom firework external cylinder body 1, and propellant powder 4 burns rapidly, and the lead 26 that ignites, fire lead-in wire 6 and tail medicine 28.When propellant powder 4 burns, gas moment undergoes rapid expansion produces boosting power, fireworks inner tank body 2 is under the effect of this boosting power, and the inwall along firework external cylinder body 1 rushes at sky, now, tail medicine 28 is lighted, and fireworks inner tank body 2 afterbody in flight course discharges pearlite and produces fireworks; The moderate length of lead 26, makes fireworks inner tank body 2 when highest point, and go between 26 after-flames the explosive mixture 25 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 6 that fires, thus makes the fireworks inner tank 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.
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.
