Go out several points, further according to these points with smoothed curve it is flat throw curve describe come.This process is quite numerous repeatedly many times
It is trivial.Rolled down per secondary guarantee same position from skewed slot from static, also to ensure the penholder central collision with described point, particularly latter point
It is difficult to hold, describing a point will repeatedly several times, and assurance is bad to also result in larger error.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of flat throwing track display instrument, the flat track of throwing is shown
Instrument when being rolled down close to magnetic drawing, will leave level throw motion by using the magnetic ball rolled down from skewed slot on drawing board
Track, solve on classroom draw level throw motion track be shown to the problem of student sees difficulty.
The utility model is achieved by the following technical programs.
The utility model provide a kind of portable flat throwing track display instrument, including box body, lid, skewed slot, magnetic ball,
Magnetic drawing, hinge and small rotating shaft；The box body and lid are flexibly connected by hinge, and magnetic drawing is fixed in the inner side of lid
It is arranged on lid, skewed slot is rotatably mounted on lid by small rotating shaft, and the end of skewed slot is arranged at the left side of magnetic drawing
Upper angle or the upper right corner, magnetic ball are positioned in the cavity formed by box body and lid.
Sandbag is additionally provided with the box body.
The magnetic drawing is embedded to be fixedly installed on lid.
The end of the skewed slot is provided with plumb line.
Adjusting screw is also respectively provided with four angles of bottom outside of the box body.
Fastened between the box body and lid by latching.
Handle is additionally provided with the outside of the box body.
The beneficial effects of the utility model are：Rolled down using a magnetic ball from skewed slot, in one piece of vertical placement
Magnetic drawing on can very easily retain the track of level throw motion.Only need once track can just be described, easily
Operation, it is convenient and practical.Magnetic drawing side is easily removed, and facilitates student to take point, measurement, experimental study is carried out to level throw motion.With
A piece magnetic strips wipe vestige from the back side of magnetic drawing, then it is laid, and may be reused, save paper.As
There is a small sandbag of strip in the tub of base, magnetic ball can be avoided to dap, it is ensured that classroom discipline.

Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
A kind of portable flat throwing track display instrument as shown in FIG. 1 to 3, including box body 1, lid 2, skewed slot 3, magnetic are small
Ball 4, magnetic drawing 5, hinge 8 and small rotating shaft 10；The box body 1 and lid 2 are flexibly connected by hinge 8, and magnetic drawing 5 is in box
The inner side of lid 2 is fixedly installed on lid 2, and skewed slot 3 is rotatably mounted on lid 2 by small rotating shaft 10, and the end of skewed slot 3
The upper left corner or the upper right corner of magnetic drawing 5 are arranged at, magnetic ball 4 is positioned in the cavity formed by box body 1 and lid 2.
Sandbag 6 is additionally provided with the box body 1, not only prevents from ejecting after magnetic ball 4 drops in box body 1 during demonstration,
The noise that collision is produced can also be reduced.
Adjusting screw 9 is also respectively provided with four angles of bottom outside of the box body 1, passes through the damper box of adjusting screw 9
Body 1 is in horizontality.
Fastened between the box body 1 and lid 2 by lock 11, the outside of box body 1 is additionally provided with handle 12.By skewed slot 3
Rotated around small rotating shaft 10, box body 1 and lid 2 is smoothly covered, fastened after lock 11, just can easily by handle 12
Lift the track display instrument.
The magnetic drawing 5 is embedded to be fixedly installed on lid 2.
The end of the skewed slot 3 is provided with plumb line 7, by adjusting adjusting screw 9 so that plumb line 7 and magnetic drawing 5
Side it is parallel, you can judge box body 1 be in horizontality.
A skewed slot 3 is installed in the upper left corner of magnetic drawing 5, and skewed slot 3 turns clockwise to pack up and conveniently moves and bear.
There is weight line 7 end of skewed slot 3.The small sandbag 6 of a strip is placed in box body 1, magnetic ball can be avoided to dap.Damper box
