Description

TECHNOLOGY FIELD:

[0001] The present invention relates to the technical field of firework manufacturing, especially relates to a new integral rectangular plastic cake fireworks.

BACKGROUND TECHNOLOGY:

[0002] There are rectangular cake fireworks made of different materials commercially available nowadays, comprising primarily gypsum and plastic one. The rectangular cake fireworks made of gypsum are mostly integrated-type ones, which means the firework barrels are connected to the base of rectangular cake fireworks. For this kind of fireworks, in case one of the firework barrels explodes, the other barrels will be affected, which is not satisfactory with regard to safety.

[0003] With respect to the rectangular cake fireworks made of plastic, the firework barrel and the rectangular cake fireworks base are usually separated. No matter how the plastic rectangular cake fireworks are designed, the separation of the firework barrel and the rectangular cake fireworks base can not compromise the stability of the fireworks, especially for a long distance transportation, which may cause the problem such as the incorrect ignition connection, and affect the effect of fireworks. In addition, the heat radiation capacity of the present fireworks is not good enough and, from time to time, something like misconnection of ignition may occur. Consequently a new kind of plastic rectangular cake fireworks is an urgent need to overcome the deficiencies detected in the current use.

DETAILED DESCRIPTION OF THE PRESENT INVENTION:

[0004] The present invention aims to provide a new integral plastic rectangular cake fireworks capable of solving the problems proposed in the background.

[0005] To realize the above goal, the present invention provides the following technical solution:
A new integral, plastic, rectangular, cake fireworks that comprise a rectangular cake fireworks body that may include a plurality of firework barrels in a matrix arrangement and a frame which encloses outside several of said plurality of firework barrels. Each of the firework barrels to the inner side of the rectangular cake fireworks body that may not contact with the outside frame is connected and fixed with a stiffening plate.

[0006] Under the firework barrels located in the central part of the rectangular cake fireworks body, a fixing plate is provided. Preferably, there are four firework barrels in the central part of the rectangular cake fireworks body.

[0007] On the bottom of the rectangular cake fireworks body, a fuse board which shows an "S" shape that is in turn connected to the bottom end of the firework barrels is also provided.

[0008] At the bottom of each firework barrel, two ignition holes are provided along the extending direction of the fuse board. An ignition slot is situated on the fuse board, between all two neighboring firework barrels, whose one end is connected to an ignition hole of a firework barrel and the other end of the ignition slot is connected to an ignition hole of the other firework barrel.

[0009] Furthermore, to front and rear sides of the fixing plate is provided a connecting plate whose end is connected to the stiffening plate.

[0010] Further, the frame, the firework barrels, the stiffening plate, the fuse board, the fixing plate and the connecting plate are manufactured by integrated molding.

[0011] Furthermore, the ignition slot may comprise a square groove and two bar grooves positioned to both sides of the square groove.

[0012] Furthermore, both the diameter of the ignition hole and the width of the bar groove are 2.8 mm.

[0013] Furthermore, the connection part between the ignition hole and the bar grooves is filleted.

[0014] Furthermore, the rectangular cake fireworks body is made of plastic material and, looking at it from a top view, the rectangular cake fireworks body has a square or rectangular shape.

[0015] Furthermore, in another embodiment, the ignition slot comprises two transversal ribs, perpendicular to a longitudinal direction of the ignition slot, positioned between each bar grooves and the square groove.

[0016] Furthermore, in another embodiment, the ignition slot comprises two transversal ribs perpendicular to a longitudinal direction of the ignition slot (6), which divide said slot into three parts.

[0017] Compared with the prior art, the beneficial effects of the present invention are shown as follow: the way to fix the fuse has been changed from parallel to a serial connection, in the new integral plastic rectangular cake fireworks; and there are two ignition holes designed on every firework barrel. Heat radiation is greatly facilitated and enough time is allowed for burning the fuse with the ignition slot wide opening, to prevent the ignition misconnection.

[0018] Experiments show that the present design could basically solve the problem of the ignition misconnection. The rectangular cake fireworks is more stable, much smoother outside and it is much easier to manufacture the outer package when it is enclosed with the frame from outside. The design of the rectangular cake fireworks base with holes improves the heat dissipation and the material costs could be saved with better environmental and economic effects. In addition, the base holes also enable that the rectangular cake fireworks don't deform easily because of the expansibility of plastics. Furthermore, if one of the firework barrels explodes, the other firework barrels would not be affected as they are made from plastic, however, it is likely that the entire firework explode when any one firework barrel does if they are made of gypsum. In this regard, the design of the present invention is much safer.
