Platform shape shock portion rear end is provided with the body of a gun, and truncated cone-shaped shock portion can also avoid software children from throwing a javelin to object or person body
It damages.The balance wing extended by pipette tips is equipped on the outside of the body of a gun, it is thus winged with software children can be made to throw a javelin
The more stable effect of row.Pipette tips, the body of a gun and balance wing are integrally formed by flexible material, convenient for production without assembling, and
Lighter weight, convenient for children use.
In some embodiments, the zufolo hole for zufolo insertion is provided in airslide, zufolo passes through the zufolo
Hole is connect with pipette tips interference, and zufolo upper end is provided with the whistle mouthful stretched out out of zufolo hole, the sky when pipette tips movement in airslide
Gas can enter zufolo from the whistle mouthful.
In some embodiments, balance wing quantity is 3, and balance wing is uniformly distributed around the body of a gun, balance wing two-by-two it
Between be mutually 120 degree of angles.
In some embodiments, the quantity of airslide be 3, airslide be correspondingly arranged at balance wing and balance wing institute at
The middle position of angle.
In some embodiments, flexible material is ethylene-vinyl acetate copolymer.Thus there can also be light weight,
Convenient for children using and due to material is soft can reduce software children throw a javelin throw when caused by execution.
In some embodiments, the sound for being provided with pressure sensor in shock portion and being electrically connected with pressure sensor
It rings, pressure sensor can will hit signal when shock portion is hit and be sent to sound equipment.
In some embodiments, balance wing is from pipette tips along the body of a gun gradually broadening balance wing.Thus can also have
Software children are made to throw a javelin the effect of head and the tail weight balancing.
The utility model has the following beneficial effects: the software children of the utility model throw a javelin by EVA (ethyl vinyl acetate second
Alkene copolymer) spray integrated molding, it is convenient for production without assembling, and lighter weight, convenient for children uses, while can also keep away
Exempt from software children and throw a javelin that people or object is caused to damage, use is safe.Several zufolos are provided in pipette tips, so that this is soft
Body children, which throw a javelin, can issue sound by zufolo in flight course, improve the interest that software children throw a javelin,
Improve the usage experience of children.
Detailed description of the invention
Fig. 1 is the three-dimensional structure diagram that a kind of software children of embodiment of the utility model throw a javelin；
Fig. 2 is the structural schematic diagram that a kind of software children of embodiment of the utility model throw a javelin.
Specific embodiment
1 and 2 pair of the utility model is described in further detail with reference to the accompanying drawing.
As illustrated in fig. 1 and 2, a kind of software children throw a javelin, including oval pipette tips 1, and thus pipette tips 1 also have and reduce
Software children throw a javelin the effect of in flight course suffered air drag.1 outside middle position of pipette tips is provided with air-flow
Slot 4, air-flow can be passed through from airslide 4 when 1 flight of pipette tips reduces air drag.1 front end of pipette tips is provided with truncated cone-shaped shock portion 7
Rear end is provided with the body of a gun 2, and truncated cone-shaped shock portion can also avoid software children from throwing a javelin damaging object or person body,
Because 7 front end of shock portion is that it is hereby ensured that software children to throw a javelin when colliding human body fragility position also not for plane
Other people can be damaged.It is equipped with the balance wing 3 extended by pipette tips 1 on the outside of the body of a gun 2, which has and can make this
Software children throw a javelin the more stable effect of flight.Pipette tips 1, the body of a gun 2 and balance wing 3 are integrally formed by flexible material,
It will be integrally formed in flexible material spray to mold.The flexible material for making the product can be the flexibilities such as foam, silica gel or latex
Material；Preferably, material employed in the present embodiment is EVA (ethylene-vinyl acetate copolymer and its manufactured rubber-plastic foamed
