Description
Technical field
The utility model relates to a kind of fireworks, particularly relates to a kind of environment protection firework inner barrel.
Background technology
Fireworks have long history in China, with its bright and colourful being loved by the people.There are at present a kind of fireworks, its structure is that inner core is housed in launching tube, cardboard is stamped in the upper end of inner core, lower end is placed with lower cardboard, between lower cardboard and the bottom of launching tube, propellant powder is housed, lower cardboard is provided with through hole, while being convenient to gun propellant combustion, the lead-in wire of inner core is ignited, during gun propellant combustion, inner core is transmitted in the air, inner core aloft explosive combustion produces bright and colourful color.The effect of upper cardboard and lower cardboard is the gap covering between launching tube and inner core, and while making gun propellant combustion, its burning gases can, from the clearance leakage between launching tube and inner core, not guarantee launching effect.But it is complicated that the shortcoming of its existence is manufacturing process, its manufacturing process is first propellant powder to be placed on to the inner bottom part of launching tube, cover again lower cardboard, then put into inner core, then cover cardboard, these are all manually to complete, manufacturing time is long, affects the production efficiency of fireworks, has improved the cost that fireworks are manufactured, and lower cardboard and upper cardboard are transmitted in the air, affect environmental sanitation.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of production cost is low, production efficiency is high and the environment protection firework inner barrel of environmentally-friendly sanitary.
In order to solve the problems of the technologies described above, the environment protection firework inner barrel that the utility model adopts, comprise inner barrel body, at the upper end sidewall of described inner barrel body, be provided with at least two strong points that become one and radially extend with described inner barrel body, the described strong point remains on the longitudinal center line of launching tube described inner barrel body, and the described strong point is concordant with the upper surface of described inner barrel body; Or in the upper end of described inner barrel body, be provided with the shirt rim becoming one with described inner barrel body, described shirt rim while using, seal up the gap between launching tube and described inner barrel body and keep described in inner barrel body in described launching tube.
The described strong point is circumferentially evenly arranged in the sidewall of described inner barrel body.
Described inner barrel body is cylindrical or back taper, the strong point described in when described inner barrel body is back taper or shirt rim are located at the large end of the described inner barrel body of back taper, large end is sealing, and the base diameter of described inner barrel body equates with the internal diameter at the propellant powder place of the bottom of described launching tube.
It is the length of the described strong point slightly larger in diameter that adds described inner barrel body in the internal diameter of the described launching tube of the described strong point and described launching tube contact position that the described strong point or shirt rim keep described inner barrel body mode on longitudinal center line in described launching tube.
The material of described inner barrel body and the described strong point or shirt rim is plastics, or paper fiber and the moulding of glue disposable tool.
The size of the described strong point, length and quantity are directly proportional to the diameter of described inner barrel body.
Adopt the environment protection firework inner barrel of technique scheme, because the upper end sidewall at inner barrel body is provided with at least two strong points that become one with inner barrel body and radially extend, the strong point remains on the longitudinal center line of launching tube inner barrel body, guarantee launching effect, the interior wall friction of the strong point and launching tube, increase the resistance that inner barrel body is gone out, the firepower of propellant powder is built the pressure in launching tube, after inner barrel body is rushed out launching tube, the firepower of propellant powder is larger, and launching effect is better.The strong point and inner barrel body become one, its manufacturing process is only propellant powder need be placed on to the bottom in launching tube, then put into the inner barrel body with the strong point, saved the time of placing lower cardboard and upper cardboard, shorten manufacturing time, improved the production efficiency of fireworks, reduced the cost that fireworks are manufactured, and do not descend cardboard and upper cardboard to be transmitted in the air, can not affect environmental sanitation.The inner space of launching tube is lower little large back taper, inner barrel body is cylindrical or back taper, the base diameter of inner barrel body equates with the internal diameter at the propellant powder place of the bottom of launching tube, the formation sealing at the propellant powder place of the bottom of inner barrel body and the bottom of launching tube, while making gun propellant combustion, its burning gases can not leak from the propellant powder of the bottom of inner barrel body and the bottom of launching tube, and launching effect is better.In the transportation of fireworks, if careless fireworks stand upside down, the interior wall friction of the strong point and launching tube, make inner barrel body fixedly remain in launching tube, can not pour out, guarantee that propellant powder can not pour out from the gap between inner barrel body and launching tube yet, guarantee fireworks quality.
Because the upper end at inner core is provided with the shirt rim becoming one with inner core, shirt rim seals up the gap between launching tube and inner core, and while making gun propellant combustion, its burning gases can, from the clearance leakage between launching tube and inner core, not guarantee launching effect.Shirt rim and inner core become one, its manufacturing process is only propellant powder need be placed on to the bottom in launching tube, then put into the inner core with shirt rim, saved the time of placing lower cardboard and upper cardboard, shorten manufacturing time, improved the production efficiency of fireworks, reduced the cost that fireworks are manufactured, and do not descend cardboard and upper cardboard to be transmitted in the air, can not affect environmental sanitation.The inner space of launching tube is lower little large back taper, inner core is cylindrical or back taper, the base diameter of inner core equates with the internal diameter at the propellant powder place of the bottom of launching tube, the formation sealing at the propellant powder place of the bottom of inner core and the bottom of launching tube, while making gun propellant combustion, its burning gases can not leak from the propellant powder of the bottom of inner core and the bottom of launching tube, and launching effect is better.
Due to the inner core of traditional fireworks and the gap coordinating of urceolus too large, in order to reach firing altitude, will increase propellant powder, cause the consumption of propellant powder many, the utility model dwindles the gap coordinating of inner core and urceolus, same firing altitude has reduced 1/3rd of propellant powder consumption, energy-conserving and environment-protective.Same firing altitude also reduced launching tube height 1/3rd, thereby reduced the volume of fireworks, be convenient to storage and transportation, reduce costs.
When traditional fireworks are installed lower cardboard and upper cardboard, because lower cardboard and upper cardboard can be out of shape, cause lower cardboard and upper paperboard card in launching tube, easily occur a fried cylinder phenomenon.The utility model adopts the strong point or skirt border structure, can make inner barrel be supported on launching tube Zhou center, there will not be card cylinder, can not explode cylinder.The gap of inner barrel and launching tube is little, has guaranteed launch accuracy.
In sum, the utility model is that a kind of production cost is low, production efficiency is high and environmental protection, energy-conservation environment protection firework inner barrel.
