Abstract
The utility model belongs to the technical field of firecrackers, particularly relates to a safe and environment-friendly single firecracker, and solves the problems that the existing safe, environment-friendly and energy-saving firecracker has a limited cracking number and is relatively difficult to create a festive atmosphere caused by the traditional firecracker. The safe and environment-friendly single firecracker comprises a fixed priming plug, a housing, a metal shell and a priming wire, wherein one end of the fixed priming plug is a table body; a through hole is formed in the fixed priming plug along the axis thereof; the table body part of the fixed priming plug is inserted into the metal shell; a cavity for accommodating gunpowder, as a gunpowder cavity, is formed between the outer end part of the metal shell and the top surface of the table body of the fixed priming plug; an opening sealing layer is arranged on the outer end part of the metal shell; and the metal shell is sleeved with the housing. The safe and environment-friendly single firecracker has the advantages as follows: the safe and environment-friendly single firecracker is very wide in application range and can be made into firecrackers with various forms and any cracking number; and any fixed priming agent or fixed primer is not used, so that advantages of the traditional firecracker and the existing safe and energy-saving firecracker are combined and safe, environment-friendly and energy-saving effects are achieved to a greater extent.
Description
Technical field
The utility model belongs to the technical field of firecrackers, is specifically related to a kind of safe environment protection type firecrackers monomer.
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:
Safe environment protection type firecrackers monomer, it is characterized in that comprising and admittedly draw plug, shell, metal-back, lead-in wire, a described end that admittedly draws plug is stage body, have through hole admittedly draw in plug along its axis direction, admittedly draw the stage body partial insertion metal-back of plug, the outer end of metal-back and admittedly drawing fill in leave between the stage body end face medicine is set cavity as the gunpowder chamber, the metal-back outer end is provided with sealing layer, the metal-back overcoat has shell, and lead-in wire one end stretches in the gunpowder chamber, and the other end is drawn through admittedly drawing the through hole of filling in axis direction.
The described other end that admittedly draws plug for the cylindrical shell of stage body smaller diameter end one.Have radially gap admittedly draw the position of the corresponding through hole of plug stage body end face.
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.
The relative prior art of the utility model has following beneficial effect:
1, the firecrackers monomer scope of application described in the utility model is extremely wide, can make various forms of firecrackers;
The use of 2, admittedly drawing plug, realize not needing to use any solid flashing composition or solid primer, not only saved time and cost on technique, and basically realized zero-emission, air pollution, dust pollution and potential safety hazard that traditional firecrackers cause have farthest been overcome
3, firecrackers monomer described in the utility model can be made the firecrackers of any loud number, and the loud number that has overcome existing safety and energy-saving firecrackers is less, build the more difficult problem of festive air,
4, 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-draws plug admittedly, 2-shell, 3-gunpowder chamber, 4-metal-back, 5-lead-in wire, 6-sealing layer.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
Safe environment protection type firecrackers monomer comprises and admittedly draws plug 1, shell 2, metal-back 4, lead-in wire 5; Admittedly drawing an end of plug 1 is stage body, plug 1 is interior has through hole along its axis direction admittedly draw, admittedly draw the stage body partial insertion metal-back 4 of plug 1, the outer end of metal-back 4 and admittedly draw plug and leave cavity that medicine is set between 1 stage body end face as gunpowder chamber 3, metal-back 4 outer ends are provided with sealing layer 6, metal-back 4 overcoats have shell 2, and lead-in wire 5 one ends stretch in gunpowder chamber 3, and the other end is drawn through admittedly drawing the through hole of filling in 4 axis directions.
Described admittedly draw plug 1 other end for the cylindrical shell of stage body smaller diameter end one.Have radially gap admittedly draw the position of the corresponding through hole of plug 1 stage body end face, what be convenient to go between penetrates.
Described metal-back 4 bottom inner bevels, metal-back 4 endoporus with admittedly draw plug 1 stage body maximum gauge place interference fit.The endoporus at the corresponding metal-back of described shell 24 positions is back taper, with metal-back 4 outer wall interference fit.The firecrackers monomer scope of application described in the utility model is extremely wide, can make various forms of firecrackers, also can make the firecrackers of any loud number, combine the advantage of traditional firecrackers and existing safety and energy-saving firecrackers, realize to a greater degree safety, environmental protection, energy-conservation.
Claims (5)
