Firecrackers for evening party

Technical field

Present invention relates in general to the ceremonially used firecracker of a kind of celebration, particularly relate to and be used for the such celebration ceremony of birthday party, wedding to improve the firecracker of celebrating atmosphere.

Background technology

Along with the growth of economy, people spend more time and are used to seek happy.Therefore, hold various ceremonies and party.

Be used for the so various article ceremonially of birthday party and wedding, firecracker is used to active atmosphere when ceremony reaches a climax.At this moment, firecracker is emitted Confetti, produces loud noise simultaneously so that ceremony has theatrical atmosphere.

Shown in Fig. 1 a and 1b, usually, traditional firecracker 10 comprises the shell 20 and the lid 30 of taper.Inside part on conical shell 20 tops is provided with the projection 21 of the annular of an inside, and its cross section is a triangle.

Moreover below inner projection 21, conical shell 20 is provided with an internal groove 22, and lid 30 is meshed with it.Conical shell has been filled a spot of gunpowder for 20 li, and conical shell has been filled various colored shredded papers, perhaps gold and silver thin slice for 20 li.

Dome 30 is engaged in the internal groove 22 on the inner surface that is formed on shell 20.

Describe below in conjunction with Fig. 1 b and will cover 30 operations that are assembled in the internal groove 22 of shell 20.Be inserted into to lid 30 being forced to property 20 li of conical shells.At this moment when it because the pliability of self and by a little ground when crooked, lid 30 is crossed inner annular projection 21.After lid 30 arrives internal grooves 22 (groove 22 is just in time below inner projection 21), when returning to normal shape, lid 30 is meshed with internal groove 22.

Ignition wire " R " is extracted out from the lower vertex of conical shell 20.The gunpowder of 20 li fillings of one end of ignition wire " R " and shell links to each other, and the other end is bonded on the outer surface of shell 20 by adhesive tape " T " etc.

Fig. 2 has provided another kind of traditional firecracker 11, and it is identical with the firecracker 10 shown in Fig. 1 b, and just shell 20 is columniform.

In traditional firecracker 10 of constructing according to above-mentioned mode, when ignition wire " R " is taken off from adhesive tape " T ", and when extracting out from shell 20, the gunpowder of shell 20 inside is owing to the action of igniting of ignition wire " R " is exploded, and lid 30 is because the explosive force of gunpowder and separating with shell 20.Cover 30 1 separation, be contained in colored shredded paper in the shell 20 from shell 20, thereby increased the atmosphere of the ceremony of celebrating just along with explosive sound shoots out.

Yet this traditional firecracker 10 that is used for party has following shortcoming.When lid 30 was pushed in the shell 20 owing to excessive external force in the process of making firecracker, lid 30 was pulled to the position below the internal groove 22, engaged with the state that tilts or twist with the inner surface of shell 20, shown in the partial enlarged drawing on Fig. 1 b right side.Thereby, between lid 30 and shell 20, formed a gap.

More particularly, when lid 30 matches with the state that tilts or twist with shell 20, and exist therebetween under the situation in gap, shredded paper in the shell 20 can not be penetrated distance enough far away, this be because the blast pressure of gunpowder explosion generation by cover 30 and shell 20 between gap portion leaked away.

In addition, traditional firecracker has a shortcoming, and promptly owing to the gap between lid 30 and the shell 20, lid 30 may not can be opened.And, since in the process of storage outside moisture by cover 30 and shell 20 between the gap be penetrated into 20 li on shell, the gunpowder that shell is 20 li has absorbed moisture.Thereby, be difficult to light gunpowder, and then reduced and lighted success rate.

(lid 30 is engaged in wherein) is smaller comparatively speaking in width and depth because internal groove 22, and lid 30 is easy to separate with it, even when acting on the external force covered on 30 some is excessive a little, it has gone with regard to the inside that is pulled to shell 20.Thus, be difficult to make the lid 30 of all firecracker products and the adhesion between the shell 20 to keep a unified value, thereby caused explode difference on the sound of difference on the product quality and product.

Moreover, use adhesive tape " T " that ignition wire " R " is bonded at shell 20 on the outer surface although be used for traditional firecracker 10 of party, the adhesion of adhesive tape " T " is weakening gradually along with the prolongation of time.

Thereby when firecracker 10 was stored for a long time, ignition wire " R " will be unclamped, and separated voluntarily with shell 20.If the ignition wire " R " of separating is inadvertently moved to or is suspended on certain article by someone, gunpowder causes accidental fire owing to the pulling of ignition wire is exploded.In another traditional firecracker, ignition wire " R " adheres on the shell with adhesive tape " T ", and the quantity and the man-hour of making the required element of firecracker 10 increase, thereby makes and make complicatedly, has reduced productivity ratio.

And, when the user forcibly spurs gunpowder in ignition wire " R " (being bonded on the shell 20 with adhesive tape " the T ") shell 20 that ignites, ignition wire " R " just landing from adhesive tape " T " before adhesive tape " T " is torn fully, thereby cause gunpowder to explode prematurely.Thus, the user can be owing to beyond thought blast is subjected to serious burn.

Fig. 3 a has provided first embodiment of the present invention to 3d.

The firecracker of first embodiment according to the invention comprises the hinge 250 of 200, one lid 300, one connecting caps 300 of a shell and shell 200.

Shell 200 forms taper.Conical shell has been filled a spot of gunpowder for 200 li, and has filled various colored shredded papers, perhaps gold and silver paillon foil.

Lid 300 forms discoid, and its diameter is identical with the upper end diameter of shell 200.Lid 300 is coupled in the shell 200 by jockey.

The embodiment of jockey describes with reference to Fig. 3 a and 3d.On the inner surface on the top of shell 200, be provided with an inner circumferential groove 210.The lower end of the circumferential surface of lid 300 is provided with the bead 310 of an annular, shown in Fig. 3 a.

The diameter of lid 300 the bead 310 preferably inside diameter with the upper end of shell 200 is identical, like this, the upper end face of shell 200 closely contacts with the circumferential area of the lower surface of lid 300, to prevent when shell 200 and lid 300 are closed, lid 300 further enters into the inside of shell 200, shown in the enlarged drawing in Fig. 3 a left side.

The outer surface of bead 310 is that the inner inclination surface with shell 200 that tilts adapts, and can make like this to cover 300 and closely contact with shell 200, shown in the enlarged drawing of Fig. 3 a.The lower end of the outer surface of bead 3 10 is provided with the projection 320 of an annular, and it is suitable for being coupled in the ring-shaped groove 210 of shell 200.

The external conical surface of shell 200 is provided with a leg-of-mutton fixedly clip 600, and it is with shell 200 whole formation, shown in Fig. 3 c.Correspondingly, ignition wire " R " is inserted fixedly 600 li in clip, can prevent ignition wire " R " and shell 200 disengagings like this.

The upper surface of lid 300 is provided with a pair of clamper 700, and clamper 700 is used for fixing ignition wire " R ", and combustion line " R " is fixed along diametric(al), shown in Fig. 3 b and 3c.Each clamper 700 all is made up of a pair of fixture block 710.The shape of two fixture blocks 710 makes the spacing that limits between them downwards and along the direction opposite with the fixing clip 600 fixedly clip that narrows down, shown in Fig. 3 b.More precisely, because that the spacing between two fixture blocks 710 narrows down downwards is less, the ignition wire in the spacing of packing into " R " almost can not be thrown off from the inside, and can remain in its position.

Because ignition wire must make progress and draw along leaving fixedly the direction of clip 600, so that ignition wire " R " is separated with fixture block 710, therefore can prevent that ignition wire " R " from unclamping voluntarily, thereby prevent owing to inadvertently spurring the blast that ignition wire " R " causes firecracker.

Hinge 250 is used for connecting cap 300 and shell 200.More precisely, hinge 250 will cover 300 part periphery and the part periphery of shell 200 upper ends links together, shown in the zoomed-in view on Fig. 3 a right side.
