Described position of admittedly drawing the corresponding through hole of plug stage body end face has radially gap.
The length of described shell grows the endoporus of part and admittedly draws the cylinder body outer wall interference fit of plug greater than the length of connector tube structure, leaves the gap between the free end of connector tubular construction and shell.Described metal-back bottom inner bevel, the metal-back endoporus with admittedly draw plug stage body maximum gauge place interference fit.The endoporus of described sealing cap 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 the 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,
Fig. 2 is the top view of connector,
Fig. 3 is the partial enlarged drawing of Fig. 1,
In figure: 1-connector, 2-draw plug admittedly, 3-shell, 4-wire lead slot, 5-Wire channel in building, 6-gunpowder chamber, 7-metal-back, 8-sealing cap, 9-lead-in wire, 10-threading, 11-sealing layer.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
Binary tandem safety and energy-saving firecrackers comprise some monomers, it is characterized in that described monomer comprises connector 1, admittedly draws plug 2, shell 3, metal-back 7, sealing cap 8, lead-in wire 9 and threading 10;
Described connector 1 comprises mid portion and the tubular construction that is integrated with it, has symmetrical gap on tubular construction as wire lead slot 4 and Wire channel in building 5, and the tubular construction overcoat has shell 3,
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 between 2 stage body end faces and medicine is set as the cavity 6 in gunpowder chamber 6, metal-back 7 outer ends are provided with sealing layer 11, and metal-back 7 overcoats have sealing cap 8;
9 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 wire lead slot 4, and threading penetrates wire lead slot 4 bottoms of each monomer.
Described connector 1 is symmetrical structure, the mid portion two ends arrange its symmetrical tubular construction relatively, the relative tubular construction projection of described mid portion, leave the gap between the free end of connector tubular construction and shell, avoided explosion time, active force is directly from admittedly drawing plug by shell, tubular construction transmission, but the active force of explosion time opposite direction has been born in the mid portion both sides of projection.The gap bottom arrange width less than the sulculus of gap as Wire channel in building, sulculus will go between, and to carry out part isolated for the heat of burning, threading ignited or blow when having avoided lead-in wire to burn, and also just avoided coming off of monomer firecrackers.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.
The length of described shell 3 grows the endoporus of part and the cylinder body outer wall interference fit of admittedly drawing plug 2 greater than the length of connector tube structure.Described metal-back 7 bottom inner bevels, metal-back 7 endoporus with admittedly draw plug stage body maximum gauge place interference fit.The endoporus of described sealing cap 8 is back taper, with metal-back 7 outer wall interference fit.Described connector 1 tubular construction endoporus bottom arranges draws the disconnecting prevention structure of filling in 2 cylindrical shells admittedly.The disconnecting prevention structure of described shell 3 endoporus bottom settings and tubular construction outer wall.Described disconnecting prevention structure is for touching button, hangnail or helicitic texture.The ingenious appropriate design of above-mentioned each structure has avoided each assembly to be ejected in the powder burning blast, is about to potential safety hazard and is reduced to zero, has also saved the operation of artificial site clearing after the firecracker setting-off.
