Abstract
The utility model relates to a rotary display table used in demonstration experiment of classroom, which is suitable to be used as the auxiliary apparatus of demonstration experiment in middle school in order to overcome the problem that demonstration experiment phenomenon can not be observed by most students in the teaching of large classroom. The utility model is characterized in that: a rotating shaft is fixed vertically at the center of a round chassis, and then a panel is made by woody board or other materials, the center of the panel is connected with the rotating shaft by a bearing, so that the panel can perform free horizontal rotation on the rotating shaft. In order to add the stability, three auxiliary posts can be connected at lower surface of the flange of the panel, three universal wheels are arranged at bottom end of the auxiliary posts. The rotary display table can solves the above problem of the prior art, thereby reaching perfect teaching effect.
Description
Affiliated technical field
The rotary show stand that the utility model uses when relating to the experiment of a kind of class demonstration is applicable in the classroom, middle school the auxiliary appliance as lecture experiment.
Background technology
China is because due to the population national conditions, all there be more than 40 student in most class, the class size of some school even reach more than 60 people, such top class in a kindergarten's teaching has a lot of drawbacks, and wherein the observation of phenomenon just is difficult to look after all classmates when class demonstration is tested.Because the restriction of experiment equipment, the phenomenon of lecture experiment often can only so just be difficult to allow the student who is sitting in each corner, classroom that the observation chance of equality has all been arranged towards a certain direction more.Responsible teacher can only take the experiment equipment holder to go to the classmate at one's side in hand, or the experiment of rotation equipment is so that allow more classmate participate in experiment as far as possible, but very inconvenient, also wastes very much instructional blocks of time.
Summary of the invention
Observe the difficulty of looking after less than most of students in order to overcome lecture experiment phenomenon in top class in a kindergarten's teaching, the utility model adopts experiment equipment is placed on the rotatable show stand, promptly make revolving lecture experiment show stand, solved above-described problem well.
The concrete technical scheme of the utility model is: according to needing (the about 20cm of radius) to do a circular base plate, the chassis circle centre position is vertically fixed a rotating shaft, utilize plank or other materials to make a panel then, the center links to each other with rotating shaft by a bearing, and panel can comparatively freely be horizontally rotated in rotating shaft.In order to increase stability, can connect three jury struts at the face plate edge lower surface, in the bottom of jury strut three universal wheels are installed.So when in use, three jury struts can rely on the free adjustment of universal wheel to make panel guarantee flatly to rotate when playing stable equilibrium's effect during rotary panel.
Great advantage of the present utility model is exactly the spinfunction that has realized the lecture experiment show stand, can guarantee in the classroom all students observation experiment phenomenon easily as far as possible, thereby can reach extraordinary teaching efficiency.
Description of drawings
Below in conjunction with accompanying drawing and concrete experimental procedure the utility model is further specified.
Fig. 1 is an embodiment principle schematic of the present utility model.
1. chassis among the figure, 2. rotating shaft, 3. panel, 4. bearing, 5. jury strut, 6. universal wheel, 7. experiment equipment,
Embodiment
Do a circular base plate (1) earlier, according to needing about radius is about 20cm, chassis (1) circle centre position is vertically fixed a rotating shaft (2), utilize plank or other materials to make a panel (3) then, the center links to each other with rotating shaft (2) by a bearing (4), and panel (3) can comparatively freely be horizontally rotated in rotating shaft (2).In order to increase stability, can connect three jury struts (5) in panel (3) rim under surface, in the bottom of jury strut (5) three universal wheels (6) are installed.So when in use, three jury struts (5) can rely on the free adjustment of universal wheel (6) to make panel (3) guarantee flatly to rotate when playing stable equilibrium's effect during rotary panel (3).
During experiment, especially wherein need the equipment of observation of students reading to be placed on the panel (3) of turntable experiment equipment (7), after the teacher assembles experimental apparatus, the student that obverts with instrument, can operate on one side, the panel (3) of rotary display platform on one side makes things convenient for the observation of students and the reading of all angles.
Claims (1)
1, a kind of lecture experiment rotary display platform, it is characterized in that: a circular base plate circle centre position is vertically fixed a rotating shaft, face plate center links to each other with rotating shaft by a bearing, face plate edge connects three jury struts, three universal wheels are installed in bottom at jury strut, and rotary panel makes panel guarantee flatly to rotate.
