Abstract
The utility model belongs to the technical field of firecrackers, particularly relates to a catamaran-series built-in safe environment-friendly firecracker, and solves the problems that the current safe environment-friendly energy-saving firecracker is limited in shooting number and is difficult to create a festive atmosphere brought by the traditional firecracker. The catamaran-series built-in safe environment-friendly firecracker comprises a plurality of monomers, wherein each monomer comprises a connecting piece and a solid lead plug; the connecting piece adopts a cylindrical structure with one closed end; the solid lead plug comprises a cylindrical body of which one end is a stand body and the other end is integrated with the small diameter end of the stand body; the cylindrical body part of the solid lead plug is inserted into the cylindrical structure of the connecting piece, and the stand body part of the solid lead plug is inserted into a metal shell; and an outer shell is sheathed outside the metal shell and the connecting piece. The catamaran-series built-in safe environment-friendly firecracker has the beneficial effects of basically realizing zero release, furthest overcoming the air pollution, the dust pollution and the potential safety hazard caused by the traditional firecracker, combining with the advantages of the traditional firecracker and the current safe energy-saving firecracker, and more realizing safety, environment-protection and energy saving.
Description
Technical field
The utility model belongs to the technical field of firecrackers, is specifically related to a kind of binary series connection built-in safety environment-friendly type firecrackers.
Background technology
The harm that people's life is brought of tradition firecrackers is well-known, for example causes serious air pollution, dust pollution, also easily causes fire and might cause personal injury to setting off personnel and surrounding and watching personnel.
Chinese patent 200610012596.2 safety, environmental protection, energy-saving type built-in firecrackers, and Chinese patent 200610012598.1 safety, environmental protection, energy-saving type built-in firecrackers.The effects,sound that these two kinds of firecrackers have thoroughly changed traditional firecrackers produces principle, when setting off, do not produce any residue of setting off, saved the various manpower and materials of cleaning residue, do not exist any injury to set off and surround and watch crowd's hidden danger, in addition the recyclable recycling of its each part.
But these two kinds of firecrackers are due to the restriction of existing processing technology, and its achieved firecrackers sound number and the time of setting off are more limited, are difficult to reach several thousand of traditional firecrackers and ring, so the more difficult celebrating atmosphere that reach traditional firecrackers of the effect of its construction.
Summary of the invention
To ring number limited in order to solve existing safety, environmental protection, energy-saving firecrackers for the utility model, the problem of the celebrating atmosphere that the traditional firecrackers of more difficult construction bring.
The utility model adopts following technical scheme to realize:
Binary series connection built-in safety environment-friendly type firecrackers comprise some monomers, it is characterized in that described monomer comprises connector, admittedly draws plug, shell, metal-back, lead-in wire and threading;
Described connector is the tubular construction of an end sealing, and the blind end of connector has fairlead and through wires hole,
The described plug that admittedly draws comprises that an end is stage body, the other end is the cylindrical shell with stage body smaller diameter end one, admittedly draw in plug and have through hole along its axis direction, admittedly drawing the shell portion of plug inserts in the tubular construction of connector, admittedly draw the stage body partial insertion metal-back of plug, the outer end of metal-back and admittedly drawing leave between plug stage body end face medicine is set cavity as the gunpowder chamber, the metal-back outer end is provided with sealing layer
Metal-back and connector overcoat have shell, and the position of fairlead and through wires hole is avoided in shell the inner;
The end that goes between stretches in the gunpowder chamber, and the other end is drawn with the lead-in wire of adjacent monomer and is connected through admittedly drawing the through hole of filling in axis direction and fairlead, and threading penetrates in the through wires hole of each monomer.
Described connector is symmetrical structure, and the centre is blind end, and blind end both sides are the tubular construction of symmetrical opening.
Described position of admittedly drawing the corresponding through hole of plug stage body end face has radially gap.
Described metal-back bottom inner bevel, the metal-back endoporus with admittedly draw plug stage body maximum gauge place interference fit.
The endoporus at the corresponding metal-back of described shell position is back taper, with metal-back outer wall interference fit.
Described connector tubular construction endoporus bottom arranges the disconnecting prevention structure that admittedly draws the plug tube body.Described shell endoporus bottom arranges the disconnecting prevention structure with connector tubular construction outer wall.Described disconnecting prevention structure is for touching button, hangnail or helicitic texture.
The relative prior art of the utility model has following beneficial effect:
The use of 1, admittedly drawing plug has realized that the utility model does not need to use any solid flashing composition or solid primer, has basically realized zero-emission, has farthest overcome air pollution, dust pollution and potential safety hazard that traditional firecrackers cause,
2, overcome the loud number of existing safety and energy-saving firecrackers less, build the more difficult problem of festive air,
3, combine the advantage of traditional firecrackers and existing safety and energy-saving firecrackers, and realized to a greater degree safety, environmental protection, energy-conservation.
Description of drawings
Fig. 1 is structural representation of the present utility model,
In figure: 1-connector, 2-draw plug admittedly, 3-shell, 4-fairlead, 5-through wires hole, 6-gunpowder chamber, 7-metal-back, 8-lead-in wire, 9-sealing layer.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
Binary series connection built-in safety environment-friendly type firecrackers comprise some monomers, it is characterized in that described monomer comprises connector 1, admittedly draws plug 2, shell 3, metal-back 7, lead-in wire 8 and threading;
Described connector 1 is the tubular construction of an end sealing, the blind end of connector 1 has fairlead 4 and through wires hole 5, independent fairlead 4 and the through wires hole 5 that arranges, the heat of lead-in wire burning is completely cut off, threading ignited or blow when having avoided the lead-in wire burning, also just having avoided coming off of monomer firecrackers.
The described plug 2 that admittedly draws comprises that an end is stage body, the other end is the cylindrical shell with stage body smaller diameter end one, plug 2 is interior has through hole along its axis direction admittedly draw, admittedly drawing the shell portion of plug 2 inserts in the tubular construction of connector 1, admittedly draw the stage body partial insertion metal-back 7 of plug 2, the outer end of metal-back 7 and admittedly draw plug and leave cavity that medicine is set between 2 stage body end faces as gunpowder chamber 6, metal-back 7 outer ends are provided with sealing layer 9
Metal-back 7 and connector 1 overcoat have shell 3, and the position of fairlead 4 and through wires hole 5 is avoided in shell 3 the inners;
8 one ends that go between stretch in gunpowder chamber 6, and the other end is drawn with the lead-in wire of adjacent monomer and is connected through admittedly drawing the through hole of filling in 2 axis directions and fairlead 4, and threading penetrates in the through wires hole 5 of each monomer.
Described connector 1 is symmetrical structure, and the centre is blind end, and blind end both sides are the tubular construction of symmetrical opening.Described position of admittedly drawing the corresponding through hole of plug stage body end face has radially gap, and what be convenient to go between penetrates.
