Abstract
The utility model is related to a kind of inertia demonstration teaching aid.It is currently used for inertia demonstration teaching aid species various, some test process are complicated, some test results not enough understand, urgent need is a kind of simple in construction, easy to operate, the clear teaching aid of experimental result is substituted.The utility model includes base, it is characterized in that setting a diving board being vertically arranged on described base, the support base of adjacent diving board is set on described base, one piece of transverse slat is placed on described support base, inner groovy is provided with the top of described fulcrum bearing, one end of the transverse slat and diving board are against spheroid is demonstrated in setting on transverse slat, a transverse groove is provided with described base, described fulcrum bearing is slidably connected at transverse groove interior energy and does lateral adjustments.Acted on certain left and right adjusting, be easy to carry out simulated test to different scenes.The position of the utility model fulcrum bearing and diving board can be adjusted within the specific limits, to simulate diving board and under different elastic force, eject after transverse slat, can demonstration spheroid be smoothly fallen into the groove of fulcrum bearing, realize the inertia test of different scenes, easy to operate so that student preferably grasps physical knowledge, visual result understands.
Description
Technical field
The utility model is related to a kind of inertia demonstration teaching aid.
Background technology
It is currently used for inertia demonstration teaching aid species various, some test process are complicated, some test results not enough understand, it is anxious
Need one kind simple in construction, easy to operate, the clear teaching aid of experimental result is substituted.
The content of the invention
The problem of the utility model exists for prior art is simple in construction there is provided a kind of inertia demonstration teaching aid, can carry out
A variety of tests, and test result is quickly obtained, it is easily understood, with certain regulatory function.
The technical solution adopted in the utility model is：A kind of inertia demonstration teaching aid, including base, it is characterised in that described
Set and placed on the support base that adjacent diving board is set on a diving board being vertically arranged, described base, described support base on base
Inner groovy is provided with the top of one piece of transverse slat, described fulcrum bearing, one end of the transverse slat and diving board are against setting is demonstrated on transverse slat
A transverse groove is provided with spheroid, described base, described fulcrum bearing is slidably connected at transverse groove interior energy and does lateral adjustments.Tool
There is certain left and right adjusting effect, be easy to carry out simulated test to different scenes.
The transverse slat sets limiting plate in fore-and-aft direction, and limiting plate prevents skew against demonstration spheroid.
Groove is provided with the diving board, the top and bottom of transverse slat are resisted against in groove.
The lower end of the diving board forms turnover piece, and turnover piece is positioned on base by fastener.
Described shell fragment is metal clips.Experiment can be repeatedly repeated, stability is good
The bottom of the base sets sucker.Ensure the steadiness of base.
The position of the utility model fulcrum bearing and diving board can be adjusted within the specific limits, so as to simulate diving board and
Under different elastic force, after ejection transverse slat, can demonstration spheroid be smoothly fallen into the groove of fulcrum bearing, realize the inertia examination of different scenes
Test, easy to operate so that student preferably grasps physical knowledge, visual result understands.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is made to describe into a line：
As shown in figure 1, a kind of inertia demonstration teaching aid, sets on base 1 and sets phase on a diving board 6 being vertically arranged, base
Placed on the support base 2 of adjacent diving board, support base at the top of one piece of transverse slat 3, fulcrum bearing and be provided with inner groovy, one end of transverse slat and diving board
6 against setting is demonstrated and is provided with a transverse groove 9 on spheroid 4, base on transverse slat, and fulcrum bearing is slidably connected at transverse groove interior energy and done
Lateral adjustments.
Transverse slat sets limiting plate in fore-and-aft direction, and limiting plate prevents skew against demonstration spheroid.Groove is provided with diving board,
The top and bottom of transverse slat are resisted against in groove.The lower end of diving board forms turnover piece 8, and turnover piece is positioned at bottom by fastener 7
On seat.Shell fragment is metal clips.The bottom of base sets sucker.
During operation, transverse slat is lain in a horizontal plane on base, in the groove on transverse slat one end insertion diving board, certain limit is played
Position effect, it is ensured that the stationarity of transverse slat, then demonstration spheroid is put on transverse slat, positioned at the top of the groove of fulcrum bearing.Operate bullet
Plate forgets relative transverse slat opposite direction side pressing, unclamps diving board after storing power, transverse slat is ejected, and demonstration spheroid is fallen into groove.According to
Need that the position of fulcrum bearing can be adjusted, to demonstrate the experiment under various positions.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above embodiment,
There can also be many similar structures change designs.One of ordinary skill in the art can be direct from the utility model disclosure
All deformations for exporting or associating, are considered as protection domain of the present utility model.
