Abstract
The utility model relates to a kind of vertical brachistochrone demonstration instrument, comprise stage body, support, acrylic track, tennis placing device, described support is positioned at the left side of stage body, support is provided with tennis placing device, tennis placing device side is provided with baffle plate, opposite side is connected with solenoid-driven Control Component, and track one end of three different curvatures is fixed on bracket end, and the other end is connected to the right side of stage body.The utility model structure is simple, demonstration is convenient, by through work of electromagnet principle, solve tennis cleverly can not discharge and the problem of card ball simultaneously, and it is safe and reliable, by self manual operation, add the interest that student learns physical knowledge, also well demonstrate the existence of brachistochrone.
Description
Technical field
The utility model relates to a kind of physics teaching and shows Instrument technology field, specifically relates to a kind of vertical brachistochrone demonstration instrument.
Background technology
On an inclined-plane, put three tracks, one is straight line, and one is brachistochrone, and one is the curve higher than brachistochrone flexibility, starting point height and emphasis height all identical.The identical bead of three quality, size is simultaneously from the downward landing of starting point, and the bead of brachistochrone arrives first terminal on the contrary, and this is because the bead on curve track first reaches top speed, arbitrarily first arrives.Straight line between 2 only has one, curve but with without several, and brachistochrone only has one.
Brachistochrone is that a circle rolls curve, and when bead falls, suffered gravity is larger along the component in track tangential direction, and the speed of whereabouts is faster.Explanation only with teacher in common teaching, student is difficult to the implication understanding brachistochrone.And the demonstration of some image teaching, be also difficult to show its meaning intuitively, student is not still about the direct feel of brachistochrone.
In brachistochrone demonstration instrument, ensure that bead can fall simultaneously, key is played a part to the accuracy of experiment, at Chinese patent application prospectus: also related to brachistochrone demonstrator in CN203070614U, but this demonstrator plateau two angles are provided with two draw-in grooves, baffle plate is provided with in draw-in groove, pull-up baffle plate allows little fall, this design can not ensure that bead falls at synchronization, the present invention adopts solenoid-driven Control Component, by the button that desktop designs, Automated condtrol, ensure bead to land simultaneously, and facilitate science popularization to demonstrate operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of vertical brachistochrone demonstration instrument, can ensure that three beads land simultaneously, and handled easily, student can demonstrate by Self-operating, show the implication of brachistochrone with dynamic form intuitively, add the enjoyment of student to Physics Learning.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of vertical brachistochrone demonstration instrument, comprise stage body, support, acrylic track, tennis placing device, it is characterized in that: described support is positioned at the left side of stage body, support is provided with tennis placing device, and tennis placing device side is provided with baffle plate, and opposite side is connected with solenoid-driven Control Component, article three, acrylic track one end of different curvature is fixed on bracket end, and the other end is connected to the right side of stage body.
On such scheme basis preferably, described solenoid-driven Control Component, comprises a solenoid valve box and expansion link.
On such scheme basis preferably, described solenoid-driven Control Component, demonstration instrument stage body is connected with corresponding solenoid-driven button.
On such scheme basis preferably, described demonstration ball is normal conventional tennis.Can prevent this equipment from showing or classroom teaching in science and technology center, long period of operation bead falls path wear.
On such scheme basis preferably, described stage body is also provided with nameplate, in order to show effect and the using method of this demonstration instrument.
The beneficial effect that the utility model compared with prior art has is: adopt common tennis that this equipment can be prevented at the path wear of Long-Time Service; Tennis riding position adopts electromagnet motion, can ensure button on push platform, electromagnet action, ensures that rapidly three beads fall simultaneously, solves tennis cleverly and can not discharge and the problem of card ball simultaneously, ensure the accuracy of experiment.And easy to operate like this, after pupil has put ball, can conveniently press the operation button.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Known with reference to Fig. 1, Fig. 2, a kind of vertical brachistochrone demonstration instrument, comprise stage body 5, support 3, acrylic track 4, tennis placing device 1, described support is positioned at the left side of stage body, support is provided with tennis placing device 1, and tennis placing device side is provided with baffle plate, and opposite side is connected with solenoid-driven Control Component, article three, acrylic track one end of different curvature is fixed on bracket end, and the other end is connected to the right side of stage body.
Known with reference to Fig. 3 and Fig. 4, three bead accommodated side-by-side are at three different acrylic tracks, left side is provided with solenoid-driven assembly, comprise solenoid valve box 2 and an expansion link 8, press solenoid-driven button 7, by expansion link 8 action, can realize baffle plate and mention at one time, bead falls simultaneously.
Described bead is common tennis, can prevent the wearing and tearing that bead falls to track when Long-Time Service of this equipment, ensure that the accuracy of experiment.
Described stage body is also provided with nameplate 6, in order to show effect and the using method of this demonstration instrument.
Whole device presents a solid and the high together state of waist, is conducive to showing in science and technology center and teaching classroom being shown, pupil also can oneself operation demonstration.During demonstration, tennis is placed on respectively three different tracks and lays end, start-up operation button, expansion link action in solenoid-driven Control Component, three spheroids roll downwards on respective track simultaneously, observe the sequencing that spheroid arrives bottom, can find that the track circuit arriving bottom is at first brachistochrone.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
