Abstract
The utility model discloses an experimental device which demonstrates a skyrider and the device comprises a flat mirror, a robot and a bottom board. The device can clearly observe the phenomenon from the little flat mirror that a 'person' whose one foot stands on the ground and the other foot is suspended in midair originally is suspended in the air with two feet and walks in the air, which fully displays the charm of flat mirror imaging. The device of the utility model is made of simple and easily obtained materials and the device has the advantages that the cost is low, the structure is simple, the effect is clear, and the like.
Description
Technical field:
The utility model relates to a kind of physics facility, relates in particular to the demonstration flying trapeze's that a kind of junior middle school physics teaching uses experimental provision.
Background technology:
The content of courses of mirror imaging rule be the emphasis of junior physics optics teaching be again the difficult point content, and break through this difficult point really best method be to allow some utilization mirror imaging rules of observation of students physical phenomenon really." flying trapeze " lecture experiment is exactly teacher's one of Physical Experiment of normal use, and its vivid and interesting is welcome by the student deeply.But this requirement of experiment experimentizes with true man with a big level crossing at present, and the comparison difficulty of drawing materials does not have manufacturer production yet, so be to replace experiment to record a video, this is unfavorable for junior middle school physics teaching.
Summary of the invention:
At the deficiency that prior art exists, the utility model has designed and has a kind ofly replaced big level crossing with the facet mirror, and with the device that the replacement true man of robot experimentize, it can satisfy the needs of junior middle school physics teaching easily.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of experimental provision of demonstrating the flying trapeze comprises level crossing, robot, base plate.A pin of described level crossing, robot all is bonded on the base plate with glue.
Experimentation of the present utility model is:
This device is lain on the horizontal table top, open the switch people that operates machine really of robot then, a leg that makes it be exposed at outside mirror lifts, and does exercises aloft.Simultaneously from robot to inside and outside level crossing, observing, will see robot all walkings aloft of two pin really, and all the time can kiss the earth.
The utilization of the utility model device be simple and easy to material make, the utlity model has advantage with low cost, simple in structure, that effect is obvious etc.
Description of drawings
Accompanying drawing is a kind of experimental provision structural representation of demonstrating the flying trapeze of the utility model.
The number in the figure explanation
1---base plate 2---robot 3---level crossing
Embodiment
How further specify the utility model below in conjunction with accompanying drawing realizes:
Embodiment
1) the long 30cm of level crossing, high 20cm.
2) the artificial high 15cm of machine, both feet can autokinetic movement.
3) the long 40cm of base plate, wide 30cm.
4) pin with level crossing, robot is bonded on the illustrated position.
5) open robot switch really, make it do exercises, observe on the opposite really in robot simultaneously, just can see that robot both feet are suspended in air walk.
Claims (3)
1, a kind of experimental provision of demonstrating the flying trapeze comprises level crossing, robot, base plate, it is characterized in that: a pin of described level crossing, robot all is bonded on the base plate with glue.
