Technical field
The utility model relates to a kind of firework launcher, especially a kind of transmitter of display shell.
Background technology
At the bottom of the transmitter of existing display shell (gun barrel) all is the plane, the propellant powder of packing into after bed mud or wooden floor are filled in the paper web bottom is made flat gun barrel, the general usefulness of launching tube be paper web, also useful plastic barrel or glass fibre reinforced plastic cylinder, also useful work durm.This emission not only is difficult to reach sets off required height, and polarization is poor, and the dose of required propellant powder is very big, and fried tube takes place easily, is difficult to reach the firework display effect purpose, and existence is seted off dangerous.
Summary of the invention
In order to overcome above-mentioned drawback, technical problem to be solved in the utility model is: a kind of transmitter of display shell is provided, can makes the emission accurate positioning of display shell, reduce dosage, and guarantee to set off safely.In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of transmitter of display shell, comprise launching tube, guide cylinder, and adopt electronic ignition device, launching tube head end opening, the bottom sealing is divided into upper, middle and lower three chambeies in the tube; The launching tube epicoele is straight-tube shape, and it is hemispherical that lumen is, and cavity of resorption is concavity; Launching tube cavity of resorption diameter is less than the epicoele diameter; Cavity of resorption device propellant powder, the display shell body is built on the cavity of resorption; Launching tube bottom end face is offered an aperture and only can be gone between by electric igniter; Described guide cylinder tightly is placed in the launching tube outer wall in the on-fixed mode and launching tube is combined into integral body.
For guarantee to fix in the display shell body is in launching tube, airtight, described launching tube lumen radius is consistent with the radius of display shell body, body is packed into and is built in lumen in the tube and can not rolls.
The utility model will be arranged to upper, middle and lower three chambeies in the launching tube tube, the launching tube epicoele is straight-tube shape, it is hemispherical that lumen is, cavity of resorption is concavity, the lumen radius is consistent with the radius of display shell body, the display shell body is built on the cavity of resorption, the shape that upper, middle and lower three chambeies are respectively different is for propellant powder is more concentrated in the tube of a small size, the impulse force that upwards produces when guaranteeing its gun propellant combustion, launching tube lumen radius is arranged to the hemisphere shape with the consistent size of display shell body, be convenient to display shell and be fixed in the lumen, cavity of resorption is arranged to concavity, is convenient to airtight the covering on the propellant powder chamber of body of display shell, make in the tube very close to each other, and the impulse force that makes progress that propellant powder is produced concentrates on the body bottom in the cavity, has guaranteed the height and the precision of its emission, also can reach the effect that reduces the propellant powder dose.
The launching tube epicoele is provided with fixedly display shell body of a seal cover.
In order to guarantee the emission accurate positioning of display shell, be convenient to regulate emission angle according to default scheme, the utility model transmitter is provided with a bottom in the bottom of launching tube, bottom top is provided with connecting thread and links to each other with the bottom of launching tube, the bottom is provided with growth base of a fruit shape, during use the base of a fruit of bottom is launched on the pedestal inserting, can the regulated at will emission angle.
Offer aperture in end face center, launching tube bottom electric igniter lead-in wire inserted the propellant powder chamber, in aperture, be provided with a fixture fixedly electric igniter go between and guarantee accurate igniting.
The sidewall of launching tube bottom has an aperture and is used for by electric igniter lead-in wire, links to each other with external ignition.
Launching tube adopts plastics to make, and the thickness of the cavity of resorption barrel of launching tube changes according to the size of display shell body, and its thickness is 2-20mm, guarantees that propellant powder dashes when penetrating in tube, does not produce fried tube.
For the ease of transporting safely, at the openend device one protection upper shield of launching tube.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the use schematic diagram of the transmitter of the utility model display shell;
Fig. 2 is the launching tube cross-sectional view of transmitter;
Fig. 3 is a launching tube bottom end view;
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments the present invention is described in detail, as shown in Figure 1 and Figure 2, is divided into epicoele 2, lumen 3 and 4 three chambeies of cavity of resorption in the tube of launching tube 1.Display shell body 13 is pressed on the accent of cavity of resorption 4, is positioned within the lumen 3, and the top of body 13 is provided with a closing cap 14; Body 13 has timing lead-in wire 6 insertions of fuse primer 16 and fills in the cavity of resorption 4 of propellant powder 5, electric igniter lead-in wire 7 is fixed on 17 of the apertures of offering launching tube 1 bottom by a tubule 18 and stretches in the cavity of resorption 4, the propellant powder 5 that electric igniter goes between in igniter head 15 and the cavity of resorption 4 of 7 one ends contacts, and the other end is drawn outside the tube by the aperture 11 of bottom sidewall; Closely be connected with external screw thread 19 by internal thread 12 between launching tube 1 and the bottom 10.
The utility model in use, at first according to default character pattern content ground arrange fix the emission substrate after, to adopt the base of a fruit of bottom 10 of a plurality of launching tubes 1 of technique scheme in the 9 insertion launching base plate holes, then guide cylinder 8 closely is enclosed within integral body of launching tube 1 outside formation, regulate the angle of emission by design effect, the other end of drawing the outer electric igniter lead-in wire 7 of launching tube 1 cylindrical shell is linked to each other with ignition, the starting ignition device, firing point duration and degree of heating 15, propellant powder 5 ignites, propellant powder 5 is lighted the timing lead-in wire 6 in the display shell body 1 simultaneously in airtight cavity of resorption 4 internal combustion, and the impulse force that produces during propellant powder 5 burnings flings in the lower end of body 13 along barrel, body 13 is risen at a high speed along guide cylinder 8 straight lines, aloft burst forth.
