the present invention is achieved through the following technical solutions: the image displaying instrument of a kind of fluorescence formula single pendulum simple harmonic motion, comprise long plank, the green fluorescence type stays light cloth, swing ball, often drive button, normally closed button, relay, motor, runner, battery case, tub, montant, rack cross-bar and axle, described montant is screwed on long plank, described swing ball adopts two suspension wire forms to hang on rack cross-bar, described tub is fixed on upper end, long plank left side, described battery case is arranged on long plank rear side upper end, described motor, relay, often drive button and runner and be arranged on upper end, long plank front side, described axle is arranged on runner, described normally closed button is arranged on long plank.
A kind of optimal way of the present invention, described battery case, relay, often open between button, normally closed button and be connected in series, described motor is connected in parallel on the circuit at battery case place, be provided with the relay main contacts on the circuit at described motor place, the described button of often opening is parallel with the relay normally open auxiliary contact.
A kind of optimal way of the present invention, is often driven button, normally closed button, motor, relay main contacts, relay normally open auxiliary contact and is formed electric device with latching circuit described relay, and operation realizes semi-automation.
A kind of optimal way of the present invention, described long plank smooth surface.
A kind of optimal way of the present invention, described swing ball are fluorescent light.
The invention has the beneficial effects as follows: use when of the present invention, the swing ball quality of guaranteeing single pendulum can not change in the process that swings, swing ball can be similar to regard particle as, guaranteed that the image of depicting is that a strict single pendulum is done the image that simple harmonic motion produces, next is that existing device is improved, and makes it use convenient and hommization.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is one-piece construction schematic diagram of the present invention;
Fig. 2 is circuit theory diagrams of the present invention;
In Fig. 1:
1, ganoid long plank 2, often drive button 3, relay 4, motor 5, runner

Embodiment
as depicted in figs. 1 and 2, the image displaying instrument of a kind of fluorescence formula single pendulum of the present invention simple harmonic motion, comprise long plank 1, the green fluorescence type stays light cloth 8, swing ball 9, often drive button 2, normally closed button 7, relay 3, motor 4, runner 5, battery case 6, tub 10, montant 11, rack cross-bar 13 and axle 12, described montant 11 is screwed on long plank 1, described swing ball 9 adopts two suspension wire forms to hang on rack cross-bar 13, described tub 10 is fixed on long plank 1 upper end, left side, described battery case 6 is arranged on long plank 1 rear side upper end, described motor 4, relay 3, often drive button 2 and runner 5 and be arranged on long plank 1 upper end, front side, described axle 12 is arranged on runner 5, described normally closed button 7 is arranged on long plank 1.
wherein, described battery case 6, relay 3, often drive button 2, be connected in series between normally closed button 7, described motor 4 is connected in parallel on the circuit at battery case 6 places, be provided with relay main contacts KA2 on the circuit at described motor 4 places, the described button 2 of often opening is parallel with relay normally open auxiliary contact KA1, described relay 3, often drive button 2, normally closed button 7, motor 4, relay main contacts KA2, relay 3, often open auxiliary contact KA1 composition with the electric device of latching circuit, operation realizes semi-automation, described long plank 1 smooth surface, described swing ball 9 is fluorescent light.
the present invention adds six joint dry cells in battery case 6, swing ball 9 uses button cell, because staying light cloth 8, the green fluorescence type can be subjected to the impact of specific band light, so usually can stay the green fluorescence type light cloth 8 to be placed in tub 10, at first the lamp of front, classroom is shut during demonstration, open the fluorescent light of swing ball 9, then rock swing ball 9 and press and often drive button 2, motor 4 was worked and drove runner 5 this moment, can see that axle 12 rotations pull rope, the movement of staying light cloth 8 along with swing and the green fluorescence type of swing ball 9, the image of single pendulum simple harmonic motion just stays on light cloth 8 in the green fluorescence type and shows, after the green fluorescence type stays light cloth 8 to encounter normally closed button 7, device will auto-breaking, can avoid like this damaging instrument because of untimely outage, the light of swing ball 9 can stay on light cloth 8 in the green fluorescence type and persist a period of time, enough show the image of single pendulum simple harmonic motion to the student, because light can leave over time so device can be recycled.
press often drive button 2 after, circuit is connected, coil gets electric, relay 3 often leaves auxiliary contact KA1 and main contacts KA2 adhesive, motor 4 must be established by cable and begin to start, owing to forming latching circuit in circuit, after often opening button 2 disconnections, still adhesive of relay normally open auxiliary contact KA1, coil is also leading to electricity, still adhesive of main contacts KA2, still operation of motor 4, press normally closed button 7, circuit disconnects, relay normally open auxiliary contact KA1 disconnects, coil blackout, main contacts KA2 also disconnects, motor 4 stops operating, namely motor 4 is just out of service after the green fluorescence type stays light cloth 8 forward positions to encounter normally closed button 7, form the semiautomatic control circuit.
The invention has the beneficial effects as follows: use when of the present invention, the swing ball quality of guaranteeing single pendulum can not change in the process that swings, swing ball can be similar to regard particle as, guaranteed that the image of depicting is that a strict single pendulum is done the image that simple harmonic motion produces, next is that existing device is improved, and makes it use convenient and hommization.
The above be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
