Abstract

The utility model discloses a pull ignition and a power source-propelling device, comprising a cylindrical plastic seat. A separator which is arranged in the plastic seat divides a hollow cavity in the plastic seat into an upper cavity body and a lower cavity body which are independent mutually; the separator is provided with a through hole the upper mouth of which is sealed with a film; medicine is filled in the upper cavity body; an upper sealing film at the upper end seals the upper opening of the upper cavity body; a plastic cover is fixedly sleeved at the upper end of the plastic seat; a pull primer is fixed in the through hole of the separator; a stay cable outside the pull primer is led in the lower cavity body; a tension spring is connected with the exterior of the stay cable; the other end of the tension spring is connected with a pull ring by a pull cable; the pull ring, the tension spring, the stay cable and the pull ring are arranged in the lower cavity body; a lower sealing opening film at the lower end of the lower cavity body seals the lower end; and a paper tube is fixedly sleeved outside the plastic seat. The utility model is one civilianized military technology, has the advantages of simple structure, low cost, high reliability, environmental influence avoidance, safe and convenient storage, transportation and use, and the like and can be widely applied to products of fireworks, pyrotechnics, and the like.

Description

Draw and send out igniting and thrust power source apparatus

Technical field:

The utility model relates generally to the igniting and the spraying device of civilian fireworks series products, and especially a kind of drawing sent out igniting and thrust power source apparatus.

Background technology:

Follow the raising day by day of people's living standard, current consumption constantly promotes.In various occasions such as marriage celebration, ceremony, festivals or holidays, for expressing happiness mood, heighten atmosphere, usually can select to spray colored ribbon, colour bar, ticker tape, and set off fireworks firecracker and fireworks.

At present, the spray pattern of colored ribbon, colour bar, ticker tape has two kinds: a kind of is the mode of compressed gas cylinder, and the shock wave that promptly utilizes Compressed Gas to produce in abrupt release is pushed in the air with being stored in colored ribbon in the paper web, colour bar, ticker tape etc., forms spray effect.The subject matter that this mode exists has: the sealing of one, Compressed Gas is difficult to reliable solution, and the product of production tends to cause decompression because of the leakage of Compressed Gas, and then causes product failure after storing a period of time, can't reach and use expection; Two, compressed air is subjected to the influence of environment temperature very big, and temperature can be accelerated the leakage of Compressed Gas, and then influences its normal use; Three, in processes such as transportation, storage, if having certain impact or push, compressed gas cylinder can be blasted.Another kind is mechanical impact (or directly) sparking mode, lights the gunpowder that is pre-installed in the paper tube, and a large amount of gases that utilize gunpowder conflagration to produce are pushed colored ribbon, colour bar, ticker tape etc. in the paper tube in the air to, form spray effect.This mode is not subjected to the influence of environment temperature, but also have some problems: the gunpowder of one, inner prepackage is a black powder, hydrophily is very strong, because the airborne moisture content of absorbing environmental causes black powder fully not burn or conflagration, influences result of use through regular meeting; Two, in processes such as transportation, storage,, can produce unexpected lighting equally if firing lock is subjected to certain impact; Three, the frame for movement of this mode or ignition mechanism complexity, the safety coefficient in production, transportation, storage and the use is lower.

The utility model content:

The utility model purpose is exactly in order to remedy the deficiency of prior art, to provide a kind of convenient, fast, reliable, safe drawing to send out igniting and thrust power source apparatus.

The utility model is achieved through the following technical solutions:

Draw and send out igniting and thrust power source apparatus, it is characterized in that: include the plastic seat of tubular, in the described plastic seat dividing plate is arranged, described dividing plate is divided into separate upper cavity and lower chamber with the cavity in the plastic seat, on the described dividing plate through hole is arranged, there is film at described through hole place suitable for reading with its involution suitable for reading; Be filled with powder composition in the described upper cavity, on having, the upper cavity upper end seals film with its upper shed involution, described plastic seat upper end fixed cover is equipped with vinyl cover, be fixed with in the through hole of described dividing plate and draw igniter cap, the described igniter cap that draws has backguy to introduce in the lower chamber outward, described backguy is externally connected with extension spring, and the extension spring other end is connected with draw ring by drag-line, and described extension spring, drag-line and draw ring all are packaged in the lower chamber.

Described drawing sent out an igniting and a thrust power source apparatus, it is characterized in that: described dividing plate downside has the ring tube, and described ring tube is communicated with through hole on the dividing plate, described draw igniter cap to be fixedly mounted on to encircle tin in.

The utility model will draw igniter cap to be installed in the plastic seat, and cavity is left at the plastic seat two ends, the medicament of dress in the upper plenum, and described medicament is non-hygroscopic, and burning is quick, and gas production is big.Dress draw ring in the following cavity; Film and lower seal membrana oralis are sealed on aluminum plastic film or composite film heat cooperation being respectively in the plastic seat two ends, to form enclosure space, guarantee that not outer the spreading with draw ring of medicament do not drop out; Be with a vinyl cover in the plastic seat upper end, when medicament burns, play the effect of piston, to strengthen spray effect.Described plastic seat draw ring one end leaves tears mouth, tears draw ring during convenient the use.

During operation, open the lower seal membrana oralis, firmly spur draw ring, drive extension spring and move downward, friction draws igniter cap to produce flame, lights medicament, and then promotes vinyl cover and move up fast along paper tube, takes objects such as colored ribbon out of.

The utility model has the advantages that:

The utility model is a kind of of military technology civil nature, have simple in structure, with low cost, reliability is high, not influenced by environment for use, storage, transportation, characteristics such as safe and convenient to use can be widely used in fireworks, the pyrotechnics series products such as firework.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

Draw and send out igniting and thrust power source apparatus, include the plastic seat 3 of tubular, in the described plastic seat 3 dividing plate 12 is arranged, described dividing plate 12 is divided into separate upper cavity and lower chamber with the cavity in the plastic seat 3, on the described dividing plate 12 through hole is arranged, described dividing plate 12 downsides have ring tube 13, described ring tube 13 is communicated with through hole on the dividing plate 12, there is film 9 at described through hole place suitable for reading with its involution suitable for reading, be filled with powder composition 2 in the described upper cavity, on having, the upper cavity upper end seals film 10 with its upper shed involution, described plastic seat 3 upper end fixed covers are equipped with vinyl cover 1, be fixed with in the described ring tube 13 and draw igniter cap 7, described drawing has backguy to introduce in the lower chamber outside the igniter cap 7, and described backguy is externally connected with extension spring 6, extension spring 6 other ends are connected with draw ring 8 by drag-line 5, described extension spring 6, drag-line 5 and draw ring 8 all are positioned at lower chamber, and there is lower seal membrana oralis 4 described lower chamber lower end with its involution, and described plastic seat 3 outer fixed covers are equipped with paper tube 11.
