Description
Technical field
The utility model relates to firework setting off equipment more particularly to a kind of fireworks catapult-launching gears.
Background technique
Fireworks are widely used among the activity such as celebrating red-letter day, celebration of people as celebrating product at present, but fireworks are quick-fried
Bamboo is explosive dangerous material, it in production, storage, transport, sell and set off etc. in links and there are many insecurity factors.
People are often to hold fireworks, by fireworks and friction when setting off the fireworks such as wiping big gun for lighting class using friction
Piece friction is thrown immediately after lighting, though such ignition way is fairly simple, but if the lead burning velocity of fireworks too it is fast then
It is easy to wound itself, safety hazard is very big；Application 2017210290813 discloses a kind of fireworks ejector, it utilizes rebound
Spring and billiards go fireworks are knocking-on, can prevent fireworks explosion from accidentally injuring itself, but since spring is using vertical longitudinally disposed,
Spring shrinks cause billiards shock less than fireworks straight up frequent occurrence during setting off fireworks, while also frequent occurrence because hitting
The impact force that ball self gravity is swung not enough causes that fireworks can not be lighted.
Summary of the invention
For above situation, the purpose of this utility model is to provide a kind of fireworks catapult-launching gears, it uses rubber band water
The structure of flat lateral connection lance lights the unsafe defect of class fireworks to overcome the prior art to set off friction, through clashing
While fireworks light it and fly away fireworks quickly outward, safe operation is avoided that the accidental injury person of setting off itself, whole
It is scientific and reasonable for structure, simple and compact, easy to install and use, wide market, convenient for promoting the use of.
To achieve the goals above, a kind of fireworks catapult-launching gear, it includes support plate, longitudinal respectively to be set to support plate in parallel
The rubber band and elastic band at top both ends, friction plate are fixed on the bottom at the top of support plate and being located at elastic band, the rubber band
Center be connected with the lance of horizontal cross setting, and the front end of lance is towards elastic band.
In order to realize structure, effect optimization, further step is: the front end of the lance is tapered end, and the cone
The end face at end is tack.
The tail end of the lance is equipped with a filament and the center of rubber band connects.
The friction plate is fixedly connected at the top of support plate using bonding way.
The utility model compared with prior art caused by the utility model has the advantages that
(I) lance that the utility model is arranged using rubber band center connection horizontal cross, after being tensioned using rubber band
Screen resilience can make lance fly away realization to clash fireworks, quickly eject so that fireworks be enable to be rubbed while lighting
It goes, effective guarantee firework display safety avoids accidentally injuring itself；
(II) rubber band and elastic band is longitudinally arranged in parallel using support board ends in the utility model, and rubber band is for launching
Lance, elastic band light fireworks, overall construction design for binding fireworks, while using the friction plate of elastic band bottom setting
It is scientific and reasonable, it is simple and compact, it is easy to use；
(III) the utility model is rubbed using the structure of rubber band horizontal cross connection lance to overcome the prior art to set off
The unsafe defect of class fireworks is lighted in wiping, while the fireworks that clashed light it and flies out fireworks quickly outward
It goes, safe operation, is avoided that the accidental injury person of setting off itself, overall structure is scientific and reasonable, simple and compact, easy to install and use, tool
There are significant economic benefit and social benefit.
The utility model is widely used in firework display and matches.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Detailed description of the invention
The attached drawing for constituting the application a part is used to provide a further understanding of the present invention, and the utility model shows
Meaning property embodiment and its explanation are not constituteed improper limits to the present invention for explaining the utility model.
Fig. 1 is the overall structure top view of the utility model.
Fig. 2 is A-A cross-sectional view in Fig. 1.
In figure: 1- rubber band, 2- lance, 21- tapered end, 22- filament, 3- elastic band, 4- friction plate, 5- support plate.
Specific embodiment
Referring to Fig.1~Fig. 2, the utility model is realized in this way: a kind of fireworks catapult-launching gear, it includes support plate 5, point
Not longitudinal rubber band 1 and elastic band 3 for being set to 5 top both ends of support plate in parallel, friction plate 4 are fixed on 5 top of support plate and position
In the bottom of elastic band 3, the center of the rubber band 1 is connected with the lance 2 of horizontal cross setting, and the front end direction of lance 2
Elastic band 3.
Refering to what is shown in Fig. 1, the front end of lance 2 is tapered end 21 in the utility model, and the end face of the tapered end 21 is tack,
The resistance that lance 2 is flown in air can be reduced using tapered end structure, to improve lance 2 to the impact velocity and punching of fireworks
Power is hit, fireworks is able to achieve and is lighted and quickly launched away by quick friction, while the end face of tapered end 21 is designed as flush configuration,
The tapered end flown 21 can be prevented to be inserted into fireworks cylinder for ensureing that fireworks tube can launch away in time；The tail of the lance 2
End is equipped with a filament 22 and connect with the center of rubber band 1, and setting filament is conducive to the lance 2 that recycling is flown away, described thin
The length of line need to guarantee that lance 2 can be mapped to the fireworks of the binding of elastic band 3；The friction plate 4 is fixedly connected on using bonding way
5 top of support plate, the friction papers that red phosphorus production can also be used in friction plate 4 replace.
As shown in Fig. 2, generally using the terylene elastic band of braiding, it has preferable resistance to elastic band 3 in the utility model
Grind performance and elasticity；The rubber band 1 preferably uses silica gel rubber band, it is made using silastic elastomer material, has
Good flexibility, toughness, tensile strength and resilience, and stability and anti-aging property are good, and it is practical new to be very suitable to this
Type uses, and can extend the service life of the utility model, to reduce operating cost.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention；It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
