Abstract
An igniting device relates to an improved igniting structure, which provides an igniting device with a high igniting strength and igniting performance. The utility model includes an ignitor which connects to the igniting tool with screw threads. The device is characterized in that the igniting tool is provided with an igniting powder box on the right, the igniting powder box has resistance wires inside, the one terminal of the resistance wire connects to a positive wire of the nut on the igniting tool by means of a leader, the leader and the igniting tool are provided with an insulation cover and pad in between, the other terminal of the resistance wire connects to a negative wire on the screw by means of the igniting tool, the igniting powder box connects to the end with a heavy caliber of the cone-shape chamber inside the ignitor.
Description
Technical field:
The utility model relates to the improvement of ignition device structure.
Background technology:
The present high-energy igniter that generally adopts, be with power frequency supply by boosting rapidly, producing 5000 volts of high direct voltages after the rectification fast, charge to storage capacitor; Adopt gas-discharge tube to make the gauge tap element, make high-voltage breakdown discharge tube on the electric capacity, to the semiconductor discharge plug discharge, produce strong pulsed arc fast.Because adopt high-tension transformer and high-voltage capacitance, its weight is big, is 3-12kg, while cost height; In addition, because discharge tube is subjected to heavy current impact, the life-span is short.The igniting of general firearms or similar device, for example igniting of balance big gun can be adopted electrothermal chemical cartridge, promptly triggers the control gunpowder by electricity and lights the realization igniting.According to present technical merit, need higher DC voltage to realize, and ignition intensity is not enough, effectively the flame distance does not reach requirement.
When bursting work, need light a fire with fuse cord usually, general fuse cord can cause problems such as cutoff or miso-fire in use; When light a fire simultaneously in the needs many places, need electric initiating or many people to light a fire simultaneously, not only inconvenience but also dangerous.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of ignition intensity height, the reliable and stable igniter of ignition performance are provided.
The utility model adopts following technical scheme: the utility model comprises igniter head, igniter head links to each other with igniter with screw thread, its structural feature is that the igniter right side is provided with igniter cartridge, has resistance wire in the igniter cartridge, one end of resistance wire links to each other with the positive wire on the nut on the igniter by guide rod, is respectively arranged with insulation sleeve, felt pad between guide rod and the igniter; The other end of resistance wire links to each other with the cathode conductor on the screw by igniter; Igniter cartridge communicates with the heavy caliber end of the conical cavity in igniter head.
The beneficial effects of the utility model:
1, ignition intensity height, flame performance are reliable and stable:
Ignition device of the present utility model is stable and reliable for performance, the ignition intensity height, and its effective flame distance can reach more than 500 millimeters;
2, easy and simple to handle:
After the utility model was connected power supply, resistance wire can be lighted the gunpowder in the igniter cartridge, and flame sprays from conical cavity; Its easy and simple to handle, safety, and simple in structure, be easy to popularize.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model comprises igniter head 3, igniter head 3 links to each other with igniter 13 with screw thread 8, igniter 13 right sides are provided with igniter cartridge 7, has resistance wire 9 in the igniter cartridge 7, one end of resistance wire 9 links to each other with the positive wire on the nut on the igniter 13 15 17 by guide rod 11, is respectively arranged with insulation sleeve 10, felt pad 12 between guide rod 11 and the igniter 13; The other end of resistance wire 9 links to each other with the cathode conductor on the screw 14 16 by igniter 13; Igniter cartridge 7 communicates with the heavy caliber end 5 of the conical cavity 4 in igniter head 3.
Be provided with red copper sealing gasket 6 between igniter head 3, the igniter 13, prevent that the flame of gunpowder ejection in the igniter cartridge 7 from going out from bound fraction between igniter head 3, the igniter 13.
The utility model gets final product with dc source, and its voltage that detonates is using terminal only to need 1.5V-2V; Be particularly suitable for open-air the use.Long distance ignition is got rid of wire voltage and is fallen, and only needs the 2-3 batteries.Resistance in the igniter cartridge 7, resistance should be between 0.5-1 ohm.
Igniter head 3 ends can be provided with connecting hole 2, so that link to each other with miscellaneous equipment with this igniter.
During use, after positive wire 17 is connected with the mains, after the positive pole of resistance wire 9, the negative pole conduction, igniter cartridge 7 is lighted; The flame that the blast that igniter cartridge 7 takes place produces is then gone out from the small-caliber end 1 of conical cavity 4, refires other article.
