Abstract
The utility model discloses a multidirectional parabolic orbit display instrument, which comprises a support and a magnetic writing board which is installed on the support. A bar magnet is installed on the magnetic writing board. The multidirectional parabolic orbit display instrument additionally comprises a launching device, wherein the launching device is installed on the support through a rotating shaft. The launching device comprises a launching support. The launching support is connected with a launcher. A force applying rod is arranged in the launcher. A spring is wound on the force applying rod. A magnet ball is additionally placed in the launcher. The magnet ball is placed in the launcher, the force applying rod is pulled rearwards to compress the spring, then the force applying rod is released and the magnet ball does parabolic motion in close contact with the magnetic writing board under the effect of stress to leave a motion track. When the motion track is required to be erased, the bar magnet on the magnetic writing board is pulled and the motion track can be erased for a next demonstration. Besides, the direction of the launching device can be changed by turning the rotating shaft on the support to conveniently demonstrate multiple parabolic motions in different directions.
Description
Technical field
The utility model relates to a kind of multidirectional parabolic orbit display instrument, is applicable to the daily teaching field.
Background technology
In the teaching of middle and primary schools, can be relevant for the content of courses of parabolic motion.Generally speaking, to the teaching of parabolic motion this respect, be to need relevant instruments used for education to demonstrate parabolic motion.But present parabolic motion experiment display instrument all can not write down object left movement locus when doing parabolic motion, therefore can not present object of which movement phenomenon more intuitively to the student.
Summary of the invention
The utility model is exactly in order to address the above problem, provide a kind of simple in structure, multiple functional, can demonstrate various projectile motions and demonstrate the multidirectional parabolic orbit display instrument of its movement locus intuitively.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme:
Multidirectional parabolic orbit display instrument comprises on support, the support magnetic wordpad is installed, and bar magnet is installed on the magnetic wordpad, also comprises emitter; Emitter is rack-mount through rotating shaft.
Said emitter includes the emission support; Emission support and a transmitter link together; The set inside of the transmitter bar of having an effect; Have an effect and be wound with spring on the bar.
Also be placed with a magnet ball in the inside of said transmitter.
The utility model utilizes small magnet to stay the principle of image at magnetic wordpad; Transmitter can stay movement locus on magnetic wordpad after launching out the magnet ball, can show the track of parabolic motion very intuitively; More help the understanding of student, improve learning efficiency projectile motion.When need wipe movement locus, the bar magnet on the pulling magnetic wordpad just can be wiped track, is convenient to demonstration next time.In addition, the rotating shaft on the swinging mounting can change the direction of emitter, so that demonstrate the parabolic motion of a plurality of different directions angles.
The beneficial effect of the utility model is: simple in structure, easy to use, multiple functional, display effect is more directly perceived.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1, support; 2, magnetic wordpad; 3, bar magnet; 4, rotating shaft; 5, emission support; 6, transmitter; 7, spring; 8, the bar of having an effect; 9, magnet ball.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
In Fig. 1, multidirectional parabolic orbit display instrument comprises on support 1, the support 1 magnetic wordpad 2 is installed, and bar magnet 3 is installed on the magnetic wordpad 2, also comprises emitter; Emitter is installed on the support 1 through rotating shaft 4.Emitter includes emission support 5; Emission support 5 and a transmitter 6 link together; The set inside of transmitter 6 bar 8 of having an effect; Have an effect and be wound with spring 7 on the bar 8.The inside of transmitter 6 also is placed with a magnet ball 9.
The utility model utilizes small magnet to stay the principle of image at magnetic wordpad; Magnet ball 9 is placed on the inside of transmitter 6; The pulled backwards bar 8 of having an effect makes its compression spring 7, decontrols the bar 8 of having an effect then; Magnet ball 9 is understood stressed and is made and pasting magnetic wordpad 2 parabolic motions, thereby stays movement locus.When need wipe movement locus, the bar magnet 3 on the pulling magnetic wordpad 2 just can be wiped track, is convenient to demonstration next time.In addition, the rotating shaft 4 on the swinging mounting 1 can change the direction of emitter, so that demonstrate the parabolic motion of a plurality of different directions angles.
