Description
Technical field
It the utility model is related to a kind of spacer bar for fireworks group basin.
Background technology
Ground fireworks display or potted flower are also referred to as in combined firework industry.Usually (the letter of single paper web is first connected into by some papery cylinders
Claim cylinder row)；Then complete to punch to insert on cylinder row and draw process, i.e., process flash hole with perforating needle on each papery cylinder, then
Lead is inserted into flash hole, makes to be connected in series to form the fiery relation of biography by lead between each papery cylinder；Some rows assemble again
Shape (also referred to as organizing basin), such as cuboid, cylinder, prism, fan body, papery tube inner chamber device transmitting medicine and
Effect part, is lighted by lead.Some products need to insert spacer bar in group basin between each cylinder row, are usually that section is four sides
The strip of shape.Fixed between cylinder row and spacer bar with glue.
Traditional spacer bar has the hollow square paper tube using strip, but its mechanical property is too poor is easily deformed,
Structural strength after fireworks group basin is inadequate, lateral deformation easily occurs；Moreover, the anti-moisture performance of this kind of structure is extremely low, in humidity
Situations such as lodging collapses, which often occurs, in the fireworks finished product stored in environment causes fireworks to fail, or even forms security risk.
For this reason, the spacer bar of industry universal is plastic foam bar now, but there are still gluing combined strength is low or right
Glue have particular/special requirement, structural strength not enough, be unfavorable for the drawbacks such as environmental protection.
Utility model content
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is to provide one kind and is used for fireworks group basin
Spacer bar, there is higher structural strength and moisture protection.In order to solve the above-mentioned technical problem, the skill that the utility model uses
Art scheme is a kind of papery spacer bar for fireworks group basin, it is characterised in that including folding the cylinder formed by single piece of cardboard
Paper tube and square paper tube, cylinder paper tube are nested in the inner cavity of square paper tube；The contact of roll paper pipe outer wall and square paper tube inner wall
Position is fixed by viscose glue；The cardboard is equipped with bending part, one end of the gluing affixed cardboard in inner side of bending part, bending part
The other end of the gluing affixed cardboard in outside；The four corners of square paper tube inner cavity outside cylinder paper tube are drier filled chambers, are done
The two-port closing of drying prescription filled chamber.
Preferably, the two-port of the papery spacer bar is closed by two lids respectively, and the lid includes connecting into
An integrally-built hollow cylinder cock body and four special-shaped cock bodys, hollow cylinder cock body corresponds to the setting of roll paper pipe port, different
The port that shape cock body corresponds to drier filled chamber is set.Further reinforcement structure intensity while closing drier filled chamber, also
Keep ventilation and light structure.
The beneficial effects of the utility model are that the papery spacer bar is formed by integrally-built folding cardboard, mechanical property
Energy is good, structural strength is high, and lateral pressure resistant ability is strong, and humidity resistance is good；Fireworks tube arrange between due to be paper and paper combination, it is gluing
Performance is good, to glue without particular/special requirement；For made fireworks after setting off, it is pure paper structure to pour out drier, easy to recycle,
The feature of environmental protection is good；The advantages that making, is light and handy economic of low cost, easy to process is also equipped with the same time, is extremely adapted to fireworks group basin to use.
The utility model is described further below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is the cross-sectional view of papery spacer bar；
Fig. 2 is the overall structure diagram of papery spacer bar.
Embodiment
Referring to attached drawing, reflect a kind of concrete structure of the utility model, the papery spacer bar bag for fireworks group basin
Include and the cylinder paper tube 2 and square paper tube 1 that form are folded by single piece of cardboard, cylinder paper tube 2 is nested in the inner cavity of square paper tube 1；Circle
The contact site of 1 inner wall of 2 outer wall of coil paper pipe and square paper tube is fixed by viscose glue；The cardboard is equipped with bending part 4, bending part
The head end 3 of the 4 gluing affixed cardboard in inner side, the tail end 5 of the gluing affixed cardboard in outside of bending part 4；Side outside cylinder paper tube 2
The four corners of 1 inner cavity of shape paper tube are drier filled chambers 6.The two-port of the papery spacer bar is sealed by two lids respectively
Close, the lid includes connecting into an integrally-built hollow cylinder cock body 7 and four special-shaped cock bodys 8, hollow cylinder cock body 7
Corresponding 2 port of cylinder paper tube is set, and the port that special-shaped cock body 8 corresponds to drier filled chamber 6 is set.
Alternatively the mode of production is the utility model：First in cardboard appropriate location by extruding bending part 4 and right on mould
The folding line of four rib body positions of square paper tube 1, and the brushing glue on relevant position are answered, bending cardboard causes cardboard head end 3
It is gluing affixed with the inner side of bending part 4, that is, form the cylinder paper tube 2；Then cardboard remainder is forward wrapped into roll paper
Pipe 2, and make it that cardboard tail end 5 and the outside of bending part 4 are gluing affixed, that is, form the square paper tube 1.To disposably it be molded again
Hollow cylinder cock body 7 and special-shaped cock body 8 on molding papery lid correspond to and are inserted in two-port, to obtain the final product.
Above-mentioned implementation is merely to clearly illustrate the technical solution of the utility model, and it is not intended that to this
Utility model makes any restrictions.The utility model has known a variety of replacements or deformation in the art, is not taking off
On the premise of from the utility model in essence meaning, the scope of protection of the utility model is each fallen within.
