Abstract

The utility model discloses a firework toy bullet, which has the advantages of high ignition and launching success rate, good bursting prevention effect and simple structure. The utility model is characterized in that the utility model comprises a shell body, an ignition charge bag, and a bottom shell wall of a propellant powder stuffing chamber, wherein the bottom shell wall is provided with fire passing holes; the bottom shell wall of the propellant powder stuffing chamber is in an arch form or in a triangular form towards firework warhead direction; the fire passing holes are opened at the arch form or triangular form bottom shell wall of the propellant powder stuffing chamber.

Description

A kind of firework toy bullet

Technical field: the utility model relates to a kind of firework toy bullet.

Background technology: the firework toy bullet of general automatic igniting emission all be provided with in the bottom of bullet the spark of an igniter pad by striker primer mixture packet generation splash into fire hole light propellant powder and launch, existing firework bomb is crossed on the flat drain pan wall that fire hole all is arranged on the propellant powder storehouse, this structure be arranged on spark that bump produces during igniter pad to propellant powder Cang Dikebi by cartridge case base one side, bullet radially more to what splash with the back, therefore the reliability of igniting is not high; Establish shock ring or point in cartridge case base and blast resistance construction that gunpowder Bao Kayu cartridge case base is connected as a single entity is set then makes and make complicatedly, shockproof effect is also bad.

The utility model content: the purpose of this utility model provides a kind of launching success rate height of lighting a fire, anti-explosion firework toy bullet effective, simple in structure.

The technical solution of the utility model comprises body, igniter pad, propellant powder is loaded chamber drain pan wall, with fire hole excessively set on the described drain pan wall, described propellant powder is loaded chamber drain pan wall and is shaped as: be the arch form shape or be the triangular form shape toward fireworks bullet direction, the described fire hole of crossing is opened on this arch form or the triangular form propellant powder filling chamber drain pan wall; Be provided with at least two igniter pad cards in described cartridge case base.

The height that described arch propellant powder is loaded the arch form of chamber drain pan wall is 0.2～20mm.

Described triangular form propellant powder is loaded chamber drain pan wall and is shaped as: an angle that is in propellant powder filling chamber chamber middle position is that the angle that drift angle, place, propellant powder filling two side, chamber form respectively is the isoceles triangle type shape at two base angles, and the angle of this drift angle is 90～179 degree.

Described propellant powder filling chamber drain pan wall is provided with 2～4 and crosses fire hole.

It is the igniter pad card of one with housing that described cartridge case base is provided with four.

The utility model adopts such scheme, and the high dead bomb of ignition success rate is few; Since be provided with in body bottom with shell case be one and the igniter pad card that is separated with igniter pad, anti-shell case explosion is effective, and makes simply with low cost.

Description of drawings: Fig. 1 is the axial cutaway view of an embodiment of the utility model.Fig. 2 is that Fig. 1 is along A-A line cutaway view.Fig. 3 is the axial cutaway view of another embodiment.

The specific embodiment: as shown in Figure 1 and Figure 2, propellant powder is loaded the drain pan wall 3 of chamber 1 and is arranged to along the curved arch form shape of fireworks bullet direction, the height of arch is 2 millimeters, on arch drain pan wall 3, be provided with four and cross fire hole 2, the aperture is all round the direction of igniter pad 4 owing to overdo, so spark is splashed into propellant powder easily and loads chamber 1 and light propellant powder.Be provided with four and body 5 all-in-one-piece igniter pad cards 6 in the bottom of housing 5, when making firework bomb, need only split type igniter pad 4 is pressed in the body from body 5 bottoms, utilize the elasticity of plastics that igniter pad 4 is blocked, igniter pad 4 bursts when emission, because igniter pad 4 and body 5 be separate component each other, so body 5 just is difficult for explosion.In Fig. 3 embodiment, the drain pan wall 3 ' of propellant powder filling chamber 1 is one and is similar to the isoceles triangle type shape that is formed drift angle by 1 liang of side direction filling chamber, propellant powder filling chamber, 1 central authorities, fireworks bullet direction that leg-of-mutton drift angle 7 angles are 170 degree.

Claims

1, a kind of firework toy bullet, comprise shell case, igniter pad, propellant powder is loaded chamber drain pan wall, with fire hole excessively set on the described drain pan wall, it is characterized in that described propellant powder filling chamber drain pan wall is shaped as: be the arch form shape or be the triangular form shape toward fireworks bullet direction, the described fire hole of crossing is opened on this arch form or the triangular form propellant powder filling chamber drain pan wall; Be provided with at least two igniter pad cards in described cartridge case base.

2,, it is characterized in that it is 0.2～20mm that described arch propellant powder is loaded the height of the arch form of chamber drain pan wall by the described firework toy bullet of claim 1.

3, by the described firework toy bullet of claim 1, it is characterized in that described triangular form propellant powder loads chamber drain pan wall and be shaped as: be in propellant powder load an angle of chamber chamber middle position be drift angle, propellant powder to load the angle that place, two side, chamber forms respectively be the isoceles triangle type shape at two base angles, the angle of this drift angle is 90～179 degree.

4,, it is characterized in that described propellant powder filling chamber drain pan wall is provided with 2～4 and crosses fire hole by claim 1,2 or 3 described firework toy bullets.

5, are described firework toy bullets by claim 1,2 or 3, it is characterized in that it is the igniter pad card of one with housing that described cartridge case base is provided with four.
