CN201318912Y - Small display shell - Google Patents

Abstract

The utility model discloses a small display shell, which comprises a body filled with effective powder, a base filled with propellant powder, an ignition fuse and a fire exposure fuse; the body is a rotating spheroid; one end point of the long shaft of the rotating spheroid is provided with a fire exposure fuse hole; the end point is arranged in the base. Compared with round small display shell products of the same specifications, the small display shell adopting the technical scheme of the utility model has larger loading capacity, larger blasting breadth in the air as well as fuller and more gorgeous shaping effect in the air. Meanwhile, the product has a novel and special appearance, which can draw more attentions than the traditional product.

Description

A kind of Small fireworks display bomb

Technical field

The utility model designs a kind of firework product, especially a kind of Small fireworks display bomb.

Background technology

Classification according to GB10631-2004 " fireworks and crackers safety and quality " national standard, the small festive firework kind product is meant and is placed on ground when setting off, and (monotubular internal diameter＜76mm) also breaks into the product of effects such as pearl head-ornaments, the sound, sibilant rale or drift aloft in emission in the main body.The body of existing this series products is circle, owing to be subjected to diameter of the projectile body and powder charge quantitative limitation, it is less that its product blasts breadth aloft, and effect is plentiful inadequately.Its sight is affected greatly.

Summary of the invention

In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of Small fireworks display bomb is provided, same specification product relatively, and it is bigger that it blasts breadth, and the effect of skydive is more plentiful.In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is, a kind of Small fireworks display bomb comprises the base of body, filling propellant powder of filling effect medicine and ignition fuse, overshoot lead wire, and described body is a rotational ellipsoid.

As a kind of preferred version of the present utility model, an end points place of described rotation ellipsoid long axis of body has the overshoot lead wire hole, and described end points is positioned at base.

Minor axis or major axis around ellipse rotate the spheroid that forms, and are called rotational ellipsoid.Two intersection points of its major axis and sphere are called the end points of major axis

Adopt the Small fireworks display bomb of technical solutions of the utility model, the circular Small fireworks display bomb product of same specification relatively, its explosive payload is bigger, and it is bigger to blast breadth in the air, and the effect of skydive is more plentiful, grand.Product appearance is novel unique simultaneously, more can attract the consumer to pay close attention to than traditional product.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is the utility model specific embodiment product appearance schematic diagram;

Fig. 2 is an A-A ' face cutaway view.

The specific embodiment

Referring to a kind of concrete structure of the utility model that Fig. 1, Fig. 2 reflected, described Small fireworks display bomb comprises body 1, the base 2 that loads propellant powder 4 and ignition fuse 3, the overshoot lead wire 5 of filling effect medicine 6, described body 1 is a rotational ellipsoid, a described end points place that is body 1 major axis of rotational ellipsoid has the hole that overshoot lead wire 5 passes through, and this end points is positioned at base 2.

When setting off, described Small fireworks display bomb places in the launching tube, light propellant powder 4 by ignition fuse 3, the Small fireworks display bomb lift-off, propellant powder 4 is by overshoot lead wire 3 blasting effect medicines 6, and the beautiful moulding of aloft bursting forth is according to ready visual contrast, adopt the open-width face of the Small fireworks display bomb of technical solutions of the utility model, will increase about 20% than same specification existing product.

The above-mentioned embodiment that the utility model is described only is for the technical solution of the utility model clearly is described, and can not be interpreted as the utility model is made any restriction.The utility model has known multiple alternative or distortion in the present technique field, under the prerequisite that does not break away from the utility model essential meaning, all fall into protection domain of the present utility model.

Claims (2)

1, a kind of Small fireworks display bomb comprises the body of filling effect medicine, the base that loads propellant powder and ignition fuse, overshoot lead wire, it is characterized in that described body is a rotational ellipsoid.

2, a kind of Small fireworks display bomb as claimed in claim 1 is characterized in that, an end points place of described rotation ellipsoid long axis of body has the overshoot lead wire hole, and described end points is positioned at base.
