Abstract
The utility model discloses a semi parabolic and oblique parabolic movement trace drawing instrument, including a gyro shape moving object, a launcher, a coordinate screen, and a sponge slot, etc. The gyro shape moving object comprises a hollow metal ring with large diameter and quality and a central axis; the launcher comprises a base and a launch engine, and the coordinate screen is formed by sticking a coordinate paper on a flat and straight wood board and is vertically placed beside the launcher. Adopting the structure that the moving object is made into the gyro shape, which makes the object have great rotary inertia and not easy to change direction when rotating in high speed, the ink sprayed from the ink-spraying hole truly draws out the movement trace of the object on the coordinate screen.
Description
Technical field: the utility model relates to a kind of drawing apparatus of demonstrating movement locus of object in Physical Experiment.
Background technology: the flat throwing of object inclined throw movements is the simplest two kinds of motions in the curvilinear motion, at present, in student experimenting, be mostly to adopt trace-point method to describe two kinds of movement locus, though have intuitive, but it is inaccurate that the student looks for each position constantly of object, is easy to generate bigger error.
Summary of the invention: the purpose of this utility model is exactly to be easy to generate problem than mistake at adopting trace-point method to describe movement locus of object, and a kind of little drawing apparatus of describing of movement locus error of design.
The purpose of this utility model is to realize like this, should flatly throw inclined throw movements track drawing apparatus and comprise top in shape moving object, launcher, the coordinate screen, parts such as sponge groove, described top in shape moving object is made up of diameter and all bigger hollow metal ring and the central shaft of quality, the two ends of circle ring center's axle are respectively jet orifice and air-inflating valve, central shaft is provided with gear, described launcher is made up of base and emission engine two parts, the motor of base internal fixation band gear, respectively there are the wedge shape positioning and the dead bolt that move along arc groove in both sides, a golden circular cone that belongs to is respectively arranged on the free end of emission engine, the other end links with the knob that has clockwork spring, described coordinate screen is to paste a coordinate paper on a straight plank, vertically be placed on the launcher next door, and with the moving object level of high speed rotation at a distance of certain distance, described sponge groove is positioned over the back of launcher.
Owing to adopt said structure, promptly the gyro shape is made in moving object, make it have bigger moment of inertia, the high speed time rotational is not easy to change direction along axle, and the ink of jet orifice ejection is depicted the track of object of which movement really on the coordinate screen.
Description of drawings: describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
The flat inclined throw movements track drawing apparatus synoptic diagram of throwing of Fig. 1
Fig. 2 launcher synoptic diagram
Among the figure: 1, power switch 2, emission switch 3, clockwork spring knob 4, dead bolt 5, wedge shape positioning 6, emission engine 7, moving object 8, sponge groove 9, coordinate screen 10, pole changer 11, knob 12, spring 13, charging connector 14, metal circular cone 15, ring pipe 16, valve 17, clockwork spring 18, gear 19, jet orifice
Embodiment: the ink of earlier top in shape moving object the inside being irritated cumulative volume 2/3rds, and fill one of its excess-three branch with gas, again moving object 7 is placed on the free end of emission engine 6, two metal circular cone 14 tips are under the pulling force of spring 12, just in time jet orifice 19 and charging connector 13 are blocked, also do not had the ink ejection even open the valve 16 of jet orifice 19 1 ends.
Press power switch 1, top in shape moving object at this moment is the high speed rotation under the drive of motor, stirs pole changer 10, can change the sense of rotation of top in shape moving object.Because therefore the top in shape structure of this object, has bigger moment of inertia, after object was launched away, the ink stream of jet orifice 19 ejections was directly depicted the track of moving object all the time perpendicular to coordinate screen 9.
Press emission switch 2, dead bolt 4 falls back on the inside, and emission engine 6 is made circular motion under the elastic force effect of clockwork spring 17, run into wedge shape positioning 5, the inclined-plane of wedge shape positioning 5 makes the engine broadening, and the top in shape object of high speed rotation at this moment breaks away from emission engine 6 and moves along a curved path with certain angle and initial velocity.
Change the position of wedge shape positioning 5, the angle in the time of can changing moving object and tiltedly throw, the speed in the time of can changing emission by the clockwork spring knob 3 rotation clockwork springs 17 different number of turns.
