Abstract
The utility model discloses an outer cylinder of a combined firework. The outer cylinder is composed of a cylinder body and a bottom plug fixedly installed at the bottom end of the cylinder body, the bottom plug is provided with a launching explosive cavity and a fire through hole, a lead installation groove penetrating through the bottom end face transversely is formed in the bottom end face of the bottom plug, a lower port of the fire through hole is communicated with the lead installation groove, and starting mix is arranged in the fire through hole. The launching explosive cavity can effectively avoid the loss of launch energy, cross firing and cylinder cracking and explosion are eliminated, the processes are simplified greatly, and reliable and efficient mechanical production is facilitated.
Description
Technical field
The utility model relates to a kind of firework external cylinder of making combined firework or ground fireworks display.
Background technology
Combined firework claims again ground fireworks display, potted flower.Its structure is that the urceolus permutation and combination arranged side by side being rolled by some paper is fixed together, and urceolus bottom is closed with mud underseal, outer tube inner chamber filling transmitting medicine and effect medicine (effect part) etc., and blasting fuse is inserted in side punching, and connects ignition fuse.Its drawback is, the first, and transmitting medicine combustion chamber can not seal strictly, causes the work done energy dissipation of burning gases, causes the transmitting dose loaded excessive, and the smog of gun propellant combustion generation is excessive, contaminated environment.The second, conventional wire structure processing technology is complicated, and production efficiency is low.Draw except cutting out, each papery cylindrical shell need to punch twice, then inserts and draw, and now mainly completes by craft.The slotting technique of drawing need to be inserted soft segment lead-in wire two ends respectively in the aperture of adjacent two cylindrical shells, is difficult to realize reliable efficient mechanization production.The 3rd, fiery phenomenon is gone here and there in existing easy appearance: the gunpowder in each urceolus cavity and effect part are not to set off program according to design sequentially to light transmitting by fuse, but occurs the almost situation of transmitting simultaneously of two or more urceolus, has destroyed firework display effect completely.
Utility model content
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of combined firework urceolus of brand new is provided, and can effectively utilize the energy of propellant powder, and the fiery phenomenon of stopping to go here and there occurs, and is conducive to mechanization production.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of combined firework urceolus, formed by cylindrical shell and the bottom plug that is installed in cylindrical shell bottom, cylindrical shell bottom nozzle is inserted on bottom plug top, it is characterized in that, the center on the top of described bottom plug is provided with propellant powder chamber, the center in propellant powder chamber is provided with the through hole that overdoes that runs through bottom plug bottom, and the upper port of the through hole that overdoes connects propellant powder chamber; The bottom face of bottom plug is provided with the lead-in wire mounting groove that traverses bottom face, and the lower port of the through hole that overdoes connects lead-in wire mounting groove; Device starting mix in the described through hole that overdoes.
The beneficial effects of the utility model are, adopt technique scheme, and described starting mix is lighted by the lead-in wire going between in mounting groove, pass fiery transmitting medicine to propellant powder chamber.Powder gases in propellant powder chamber constraint urceolus can only upwards be gone out from urceolus upper end open.As from the foregoing, the utility model can effectively be avoided emitted energy loss, reduce and specification gunpowder consumption; Stop the fiery phenomenon of string simultaneously and occurred, improved and set off quality, and ensure product safety; And lead-in wire only need pack in lead-in wire mounting groove and capping is fixed, the biography fire between lead-in wire and propellant powder is completed by starting mix, no longer needs lead-in wire to insert urceolus, and technique is simplified greatly, is conducive to realize reliable mechanization production efficiently.
Preferably, described bottom plug is made up of insertosome two parts of columniform pedestal and truncated cone-shaped.Make the assembling of cylindrical shell and bottom plug firmly quick.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Brief description of the drawings
Fig. 1 is that the utility model is specifically implemented overall structure principle schematic;
Fig. 2 is the A-A section structure for amplifying principle schematic of bottom plug shown in Fig. 1.
Detailed description of the invention
Referring to accompanying drawing, reflect a kind of concrete structure of the present utility model, described combined firework urceolus is made up of cylindrical shell 1 and the bottom plug 2 that is installed in cylindrical shell 1 bottom, the center on the top of described bottom plug 2 is provided with propellant powder chamber 201, the center in propellant powder chamber 201 is provided with the through hole 202 that overdoes that runs through bottom plug 2 bottoms, and the upper port of the through hole 202 that overdoes connects propellant powder chamber 201; The bottom face of bottom plug 2 is provided with the lead-in wire mounting groove 203 that traverses bottom face, and the lower port of the through hole 202 that overdoes connects lead-in wire mounting groove 203; Described bottom plug 2 is made up of insertosome 220 two parts of columniform pedestal 210 and truncated cone-shaped.The interior device starting mix of the described through hole 202 that overdoes, described starting mix is made up of the component of following weight ratio: 40 grams, potassium nitrate, 50 grams of active carbons, 5 grams, sulphur, 5 grams, charcoal.Sieve and mix by conventional method.
By multiple described combined firework urceolus group Pengcheng types, specification, as 16,20,25, is embedded in lead-in wire capping notch anchor leg at the lead-in wire mounting groove 203 of each urceolus, and connects ignition fuse; In emission cavity, pack common black powder propellant powder by conventional method into, and pack effect part into.Obtain combined firework.
Described combined firework and existing product are carried out to contrast test detection, both urceolus materials, highly, bore is consistent, propellant powder is identical, effect part and packing method thereof are consistent, lead-in wire material is consistent, external environment condition is identical.Detection method is carried out according to GB10631-2013, and testing result shows, under identical operating mode, reaches the transmitting dose that same transmit height uses, and combined firework urceolus of the present utility model is lower by 60～65% than existing product.
The above-mentioned implementation that the utility model is described is only for the technical solution of the utility model is clearly described, and can not be interpreted as the utility model is made to any restriction.The utility model has known multiple substituting or distortion in the art, not departing under the prerequisite of the utility model essential meaning, all falls into protection domain of the present utility model.
