Abstract
The utility model discloses an improvement structure of cylindricality fireworks display bullet, including integral cartridge case, the cartridge case is separated for two upper and lower chambeies, and the propellant powder is filled to the cavity of resorption, and blasting powder, effect medicine or effect piece are filled to the epicoele, overacting lead wire runs through propellant powder and blasting powder are connected to two upper and lower chambeies, the propellant powder that ignites is connected to igniter fuse one end. Use all firework medicines of cartridge case device instead, the medicine loads simple accurate, has simplified the production technology greatly, abandon the dangerous operation that the two halves cylindrical shell folds, stopped the potential safety hazard, improved production safety nature by a wide margin, and the product shape after the improvement is unanimous with the existing product, and transmission instrument and mode need not to change, cylindricality fireworks display bullet is required touchs off the effect and can set up as required in the cartridge case equally, so the product after the improvement has kept the highly uniform with the traditional product, is approved by market easily.
Description
Technical field
The utility model relates to a kind of cylindricality display shell.
Background technology
Display shell refers to that body is transmitted in the air from launching tube, can break into the firework product of various design or other effect.As the body of display shell main body, in-built bursting charge, effect medicine (as bright pearl, powder column etc.) or effect part (as handle), body is based on spherical and cylindrical two kinds, and wherein cylinder projectile is called cylindricality display shell.Wherein specification less in the industry also referred to as cylindricality Small fireworks display bomb, its structure, effect and production technology are all similar to cylindricality display shell, are referred to as cylindricality display shell in this patent.In production, the cylinder blanket of cylindricality display shell is divided into upper and lower two cylindrical barrel shells, after filling up bursting charge and bright pearl respectively, two cylindrical barrel shells are closed up, with adhesive tape, the overlap joint mouth of two cylindrical barrel shells is cemented closed, then shaping through operations such as deposited ball, drying, the installations of transmitting medicine box.
Because the medicine in shell needs to fill closely, so the pyrotechnic composition in two cylindrical barrel shells is filled very full, need when closing up to apply certain pressure.Cause this operational hazards degree higher, this operation is simultaneously all manually manual completing, and causes the probability of personal injury higher when there is accident.The production of cylindricality display shell is made to become the high operation of danger classes.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, provides a kind of structure-improved of cylindricality display shell, under the prerequisite ensureing firework display effect, reduces the danger that cylindricality display shell is produced.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of structure-improved of cylindricality display shell, is characterized in that, comprises monoblock type cartridge case; Described cartridge case is divided into upper and lower two chambeies, and cavity of resorption fills propellant powder, and epicoele fills bursting charge, effect medicine or effect part; Overshoot lead wire runs through described upper and lower two chambeies, connects propellant powder and bursting charge; Ignition fuse one end connects the propellant powder that ignites.
The beneficial effects of the utility model are, the cylindricality display shell after improvement, use all firework gunpowders of cartridge installation instead, and medicine filling is simple and easy to do, enormously simplify production technology; Abandon the risky operation that two halves barrel shell closes up, stopped potential safety hazard, significantly improve production security; And shape of product after improvement is consistent with existing product, emission tool and mode are without the need to change; Firework display effect required for cylindricality display shell can be arranged as required equally in cartridge case, so the product after improvement maintains highly consistent with traditional product, is easily approved by market.
Preferably, the bottom sealing of described cartridge case adopts duplex paper chip architecture, comprises the outer scraps of paper of inner sheet and the closed cartridge case bottom nozzle compressing described propellant powder.Ensure safety.
Preferably, the separation in upper and lower two chambeies of described cartridge case adopts mud head layer.While ensureing isolation, the thickness benefits of mud head layer is in opening quick-fried delays time to control.
For ensureing safety.Preferably, the top seal of described cartridge case adopts one of following A, B structure;
A. sequentially comprise from bottom to up compress pyrotechnic composition lower floor's scraps of paper, fill oxidant layer, compress fill the upper strata scraps of paper of oxidant layer, nozzle closes the scraps of paper;
B. sequentially comprise the lower floor's scraps of paper be laminated on pyrotechnic composition, the middle level scraps of paper and the upper strata scraps of paper from bottom to up, also comprise nozzle and close the scraps of paper.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Accompanying drawing is the sectional structure schematic diagram of the utility model cylindricality display shell.
Detailed description of the invention
See accompanying drawing, reflect a kind of concrete structure of the present utility model, the structure-improved of described cylindricality display shell comprises all-in-one-piece cartridge case 105; Described cartridge case 105 is divided into upper and lower two chambeies by mud head separation layer 104, and cavity of resorption fills propellant powder 106, and epicoele fills bursting charge 102 and bright pearl 103; Overshoot lead wire 107 runs through described upper and lower two chambeies, connects propellant powder 106 and bursting charge 102; Ignition fuse 108 one end connects the propellant powder 106 that ignites.The bottom sealing of described cartridge case adopts duplex paper chip architecture: comprise and compress the inner sheet 109 of described propellant powder 106 and the outer scraps of paper 110 of closed cartridge case bottom nozzle.The top seal of described cartridge case adopts A structure: sequentially comprise from bottom to up compress bursting charge 102 and bright pearl 103 lower floor's scraps of paper 113, fill oxidant layer 111, compress the upper strata scraps of paper 112, the nozzle of filling oxidant layer and close the scraps of paper 114.When adopting B structure, only the filling oxidant layer 111 middle level scraps of paper need be substituted.
Its production procedure is sequentially: in cartridge case, suppress mud head separation layer 104 and device overshoot lead wire 107, epicoele fill bursting charge 102 and bright pearl 103, on 108 installations are drawn in end closure, igniting, cavity of resorption fills and launch medicine 106, lower end closure.
As from the foregoing, compared with traditional structure, the production technology of the cylindricality display shell after improvement simplifies greatly, has abandoned the risky operation that two halves barrel shell closes up, and has stopped potential safety hazard, has significantly improve production security.
The above-mentioned implementation that the utility model describes is only to clearly the technical solution of the utility model is described, and can not be interpreted as and make any restriction to the utility model.The utility model has known multiple alternative or distortion in the art, under the prerequisite not departing from the utility model essential meaning, all falls into protection domain of the present utility model.
