Abstract

The utility model discloses a firework base device which is used for supporting when fireworks are set off. The firework base device consists of a base plate seat (1) and a firework body (3); the base plate seat is fixedly connected with the firework body; peripheries of the base plate seat (1) are movably connected with folding plate blocks (2) for folding to gather up by downwardly overturning or horizontally unfolding through folding sides (4); the folding plate blocks are of an isosceles triangle shape; when the folding plate blocks are folded to gather up, the vertex angles of isosceles triangles are in matching connection with each other corresponding to a center point of the base plate seat through folding to construct a shape with a size equal to that of the base plate seat (1); the peripheries of the base plate seat are smaller than the bottom side of a vertical plane of the firework body; when the folding plate blocks (2) and the base plate seat (1) are unfolded, a shape of a square or a rectangle or a hexagon or a rhombus or a suitable shape is constructed; and the base plate seat (1) and the folding plate blocks (2) are made of a solid fiberboard material which is manufactured by dinting. The firework base device has the advantages of simple structure, easiness in manufacture, convenience in folding and packaging, increased stress surface when the fireworks are set off standing on a ground surface, good stability and the like.

Description

A kind of Base for fireworks device

Technical field

The utility model relates to a kind of Base for fireworks device, and this technology belongs to fireworks and makes the field.

Background technology

In the prior art, the fireworks that small-scale terrestrial is seted off, all be to adopt that built-in or overcoat installs a plastic feet in the bottom of its product of setting off fireworks, the employing one monoblock hardboard that has and the bottom of firework product be affixed to become base, and firework product is standing up ground surface launching or injection when setting off, the stability that the size of base area and product are seted off has direct relation, base is too little, it is little that firework product is erect the lifting surface area of setting off on ground, its poor stability, overturning oblique fire (spray) easily, very easily cause and hurt sb.'s feelings and fire incident, the bedplate area is too big, and no doubt product is erect the good stability on ground, yet, the base that area is bigger takies the cabinet space area when the packing vanning big, reduce the capacity of every case product, increased production cost, also increased the cost of transportation expense simultaneously; At present, a kind of collapsible base that is used for the fireworks display launching tube is arranged, though can the both sides doubling and base size on an equal basis, still having two after the doubling, to exceed cylindrical shell to the base vertically a lot of to the base, are not easy to packing and vanning equally, and remaining further, innovation solves.

The utility model content

The purpose of this utility model is that a kind of Base for fireworks device will be provided, fireworks cylinder places on this device the Base for fireworks lifting surface area is increased, deployable support and collapsible gathering in the vanning storage and transport process when being convenient to set off again, its folding rear base periphery that draws in is less than fireworks body vertical plane base.

To achieve these goals, the technical solution of the utility model employing is:

A kind of Base for fireworks device; it comprises bottom block, fireworks body; described bottom block is fixedlyed connected with fireworks body lower surface; its special character is: described bottom block four-way is to be connected with folding plate by folded edge, and this folding plate can overturn downwards along folded edge and fold gathering or become planar development to support with bottom block.

As improvement of the technical scheme, described folding plate is the isoceles triangle shape, folding the coincideing of the corresponding bottom block central point of the drift angle of each isosceles triangle joined when making folding gathering the in, and become stromatolithic structure with the bottom block bottom surface, folded sheet block structure shape after it is folding and big I and the equal shape of bottom block are big or small or less than bottom block, the periphery of described folding back bottom block should be less than fireworks body vertical plane base.

As improvement of the technical scheme, the deployment configuration shape of described folding plate and bottom block can be square or rectangular or hexagon or the circular or suitable geometry of rhombus, the structure form that the shape of described bottom block can match with the fireworks body.

As improvement of the technical scheme, described bottom block is to form folded edge with the solid fiberboard material through impression to be connected structure with folding plate, also can paste with the toughness soft material and be connected engagement formation with wood materials or plastics or sheet metal or composite, can adopt hinge to be connected or other movable connected mode between its folded edge and bottom block limit and the folding plate base coupling that matches, folding plate and bottom block.

Advantage and the beneficial effect that the utlity model has are:

1, simple in structure, processing and manufacturing is easy, and the production cost is low, launches the back and erects ground and fireworks body lifting surface area is increased be twice above, sets off not rewinding, good stability.

2, adopt the technical solution of the utility model,, solved shaped article and packed the problems such as area is big that take up room, reduced packing and cost of transportation expense widely because base device has collapsible gathering function.The utility model can be widely used in the base of firework products such as fireworks display class that small-scale terrestrial sets off, spraying decoration class the needs that can satisfy the product assembling and set off are installed.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 show the preferred embodiment of a kind of Base for fireworks device of the present utility model.Its formation: comprise bottom block 1, folding plate 2, fireworks body 3, folded edge 4; bottom block 1 is gluing fixedlying connected with fireworks body 3; design feature is: described bottom block 1 four-way edge is shaped on four folded edge 4 and four folding plates 2 that form through impression and is hinged; this folding plate 2 can be overturn downwards along folded edge 4 fold gathering or become planar development to support, have a rectangular shape with bottom block.

In embodiment of the present utility model, described folding plate 2 is the isoceles triangle shape, folding the coincideing of the corresponding bottom block central point of the drift angle of four isosceles triangles joined when making folding gathering the in, and become stromatolithic structure with bottom block 1 bottom surface, folded sheet block structure shape and big I and bottom block 1 equal shape size after it is folding, lamination shape after it folds when different structure form also can be less than bottom block, and the four-way side of described folding back bottom block should be less than fireworks body vertical plane base.

In embodiment of the present utility model, as Fig. 4, shown in Figure 5, described folding plate 2 also can be rhombus or hexagon with the deployment configuration shape of bottom block 1, can also be rectangle or triangle or circular or other geometry that is suitable for.
