Abstract
The utility model discloses a firecracker fire-base, which is mainly characterized in that a firecracker barrel is provided on the base. The better shape of the firecracker barrel is inverted cone-tube in shape, which can be suitable for firecrackers of various diameter and is universal. The base and the firecracker barrel can be designed as one body or separating connection, such as adopting the connecting model of block button or screw. When the firecracker fire-base of the utility model is used, firecracker is putted in the firecracker barrel to fire, then the firecracker can stablely and vertically stand, can vertically rise when fired, which can effectively prevent the dangerous phenomenons of oblique flying and mess flying of the fired firecracker. As the first blast occurs in the firecracker barrel, the power produced by the blast are centralized in the bottom of the firecracker barrel and can form a strong up-thrust, so the vacated height of firecrackers is greatly increased, and the sound effect of firecrackers can be improved too.
Description
Technical field
The utility model relates to the base used specially of a little letting off firecrackers, and specifically a kind of firecracker point is put seat.
Background technology
People in daily life, whenever the celebrating happy festival time, the firecracker of all will setting off fireworks.When firecracker is seted off, usually it is stood on ground, light a fuse then.Because the firecracker profile is elongated, be placed on the ground and be difficult for standing firm, lighting the back overturning or being fallen by wind, casualty accident can appear especially.In addition, in the majority with " double-bang firecracker " class in the firecracker kind, so-called " double-bang firecracker " is meant through twice blast, and the blast back produces the impulsive force to ground for the first time, utilizes the reaction force on ground as propulsive force firecracker to be soared, and produces blast for the second time then aloft.Because the firecracker bottom section is open, a large amount of gases of blast back generation are released at once for the first time, so the height of arch of firecracker is limited, produce blast for the second time easily in dropping process, bring potential safety hazard.
Summary of the invention
Thereby to be solved in the utility model be existing firecracker point when putting easy overturning be unfavorable for safe problem.
What the utility model also will solve is the not enough problem of height of arch behind firecracker of existing firecracker.
The technical scheme that addresses the above problem employing is: the firecracker point is put seat, comprises base, and its main feature is also to be provided with on the described base gun barrel.
Firecracker point of the present utility model is put seat, during use firecracker is placed in the gun barrel point and puts, and makes the firecracker can be steadily upright, lights the back vertical lifting, has prevented from effectively that firecracker from lighting to retread dangerous phenomenon such as to fly, disorderly fly and produce.And because blast is carried out in gun barrel for the first time, the concentration of energy that the blast back produces forms stronger last thrust, thereby has improved the height of arch of firecracker greatly at the bottom of tube, also can improve the effects,sound of firecracker simultaneously.
Described gun barrel shape is advisable with cylindrical shape or back taper tubular, preferred latter's structure.The gun barrel of back taper tubular can be fit to the firecracker of various outer diameter, has versatility.Described gun barrel can integral body all be the back taper tubular, also can be wherein one section be the back taper tubular, for example nozzle partly is the back taper tubular, or the tube bottom branch is the back taper tubular.The cross section of gun barrel can rounded or polygon, latter's structure optimization 6 to 12 limit shapes.
Described base and gun barrel can be integrated designs, also can be that dismountable type connects, and for example adopt connecting modes such as buckle, screw.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the utility model cylindrical shell integral body is the back taper tubular.
Fig. 2 is the structural representation that the utility model cylindrical shell nozzle partly is the back taper tubular.
Fig. 3 is the structural representation that the utility model cylindrical shell tube bottom branch is the back taper tubular.
Fig. 4 is the cylindrical circular structural representation of the utility model cylindrical shell.
The specific embodiment
With reference to Fig. 1, the firecracker point is put seat, and base 4 is provided with gun barrel 3, and cylindrical shell integral body is the back taper tubular.During use, the base of point being put seat places ground 5, and then with the vertical cylindrical shell that inserts of firecracker 1, to the firecracker external diameter with after cylinder internal diameter is consistent, firecracker is blocked the back by cylinder inboard wall and locatees, and lights a fuse and can set off after 2.
Firecracker point of the present utility model is put seat and can also be designed to the cylindrical shell nozzle and partly be back taper tubular (as shown in Figure 2), cylindrical shell tube bottom and minute be back taper tubular (as shown in Figure 3), and perhaps cylindrical shell cylindrical (as shown in Figure 4) all can reach the effect that point of safes is put.Experiment showed, that adopting firecracker point of the present utility model to put the seat point lets off firecrackers, the height of arch of firecracker can reach the twice of not using when establishing mounted point and putting.
The utility model is not limited to above-mentioned embodiment.
Claims (5)
1, the firecracker point is put seat, comprises base (4), it is characterized in that also being provided with on the described base gun barrel (3).
2, firecracker point as claimed in claim 1 is put seat, it is characterized in that described gun barrel has at least one section to be back taper.
3, firecracker point as claimed in claim 1 or 2 is put seat, it is characterized in that described gun barrel cross section is rounded.
4, firecracker point as claimed in claim 1 or 2 is put seat, it is characterized in that described gun barrel cross section is polygon.
