Abstract
The utility model discloses a fireworks section of thick bamboo paper gasket piece of a difficult fried section of thick bamboo, including mainly used installs additional on the cartridge type combination fireworks shell, the paper gasket piece is equipped with porously. The utility model discloses effectually having reduced the biggest chamber pressure, effectually having avoided a fried section of thick bamboo, product quality is stable.
Description
Technical field
The utility model relates to a kind of oil duct device, particularly relates to a kind of fireworks tube paper gasket of not easily fried cylinder.
Background technology
In the development of more than 1,000 years, fireworks and firecrackers has been not only a kind of custom, and more become a kind of culture, this culture continues into the present always, and has walked out the gateway of a country together, spread all over the whole world along with the interchange of Chinese and Western culture in Middle Ages.Along with people's liking fireworks, consumer requires more and more safer, environmental protection, and product is more smart, the firework product of better effects if.The fireworks that interior cartridge type combined firework is made up of two paper webs, the bottom dress propellant powder of urceolus is transmitted into inner core high aerial, inner core is the skyborne various flower pattern of effect part i.e. fireworks, multiple this have the fireworks of inner/outer tube to combine to be exactly in cartridge type combined firework.
Due to theoretical research and the quantitative analysis deficiency of interior cartridge type combined firework, make the opposition contradiction reducing production cost and improve its security change, want progressively to change nauseating circulation, improve the security of combined firework, also must set about from secure context.The most fearful when combined firework is seted off is occur fried cylinder, fried cylinder will cause loose cylinder and inner core track to change, wound personnel, the air-tightness of the combined firework monotubular of the pad with an aperture is very poor, be difficult under conventional charge amount make effect tube reach predetermined altitude, but the increase of dose can make gun pressure instability easily cause fried cylinder, and cost also strengthens, how improving this present situation is the technical problem that those skilled in the art need solution badly.
Utility model content
The purpose of this utility model is the weak point overcome in prior art, provides a kind of fireworks tube paper gasket of not easily fried cylinder.
For achieving the above object, the technical scheme that the utility model provides is: a kind of fireworks tube paper gasket of not easily fried cylinder, be installed on combined firework inner core, described paper gasket is provided with porous.
Preferably, described paper gasket is provided with 5 holes.
A technical scheme tool in technique scheme has the following advantages or beneficial effect: be with the air-tightness of the combined firework monotubular of the pad of an aperture very poor in prior art, when being difficult under conventional charge amount, effect tube reaches predetermined altitude, but the increase of dose can make gun pressure instability easily cause fried cylinder, and cost also strengthens.The utility model paper gasket offers porous, effectively reduces maximum bore pressure, effectively avoids fried cylinder, constant product quality.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, simple introduction is done below by the accompanying drawing used required in embodiment or description of the prior art, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model prior art structural representation;
Fig. 2 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1, the air-tightness of the combined firework monotubular of the pad of a prior art band aperture is very poor, when being difficult under conventional charge amount, effect tube reaches predetermined altitude, gun pressure is unstable, easily cause fried cylinder, the paper gasket in a band hole is mainly used for inner core and starts to exchange fire (propellant powder ignite the ignition powder on effect tube).
The fireworks tube paper gasket of a kind of not easily fried cylinder that the utility model provides, be installed on combined firework inner core, paper gasket is provided with porous.As shown in Figure 2, paper gasket is provided with 5 holes.
The fireworks tube paper gasket of a kind of not easily fried cylinder of the present utility model, improve the security performance of combined firework, the paper gasket installing band porous additional makes firework technology constantly reform, break the conventional art production model that fireworks and firecrackers more than one thousand years comes, provide strong technical support and guarantee to the prodution and development of fireworks and firecrackers enterprise, its economic benefit brought and social benefit are all obviously.
Apply specific embodiment herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
Claims (2)
1. not easily explode a fireworks tube paper gasket for cylinder, be installed on combined firework inner core, it is characterized in that: described paper gasket is provided with porous.
2. the fireworks tube paper gasket of a kind of not easily fried cylinder according to claim 1, is characterized in that: described paper gasket is provided with 5 holes.
