Abstract
The utility model provides an inclined surface teaching aid with randomly adjustable gradient, in order to realize the inclined surface with the gradient randomly adjustable. The teaching aid consists of an inclined panel, a movable supporting leg and a rack frame, and is characterized in that the movable supporting leg is arranged below the inclined panel; and the horizontal rack frame is arranged below the movable supporting leg, and connected with the back of the inclined panel by a loose leaf. The inclined surface teaching aid has the advantages of simple structure, convenient use and good effect of random gradient adjustment.
Description
Technical field
The utility model relates to a kind of teaching aid.
Background technology
Need carry out two experiments when present primary school science is levied for the teaching on inclined-plane: 1. ramp effect is tested the experiment of 2. different gradient ramp effect.Longer because of the more spended time of experiment content, the classroom benefit is not high not ideal.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of teaching inclined-plane teaching aid that can change the gradient arbitrarily, just can reach the purpose on any change gradient inclined-plane.
The technical scheme in the invention for solving the technical problem is: by skewback, removable supporting leg, the teaching inclined-plane teaching aid that can change the gradient arbitrarily that rack frame is formed, it is characterized in that: under skewback, be provided with one and move supporting leg, divide into a horizontal rack frame and the skewback back connects together by loose-leaf at mobile supporting leg again.
The beneficial effects of the utility model are: simple in structure, easy to use, to change the gradient arbitrarily effective.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation.
1. skewbacks among the figure 2. move supporting leg, 3. rack frame.
Embodiment
Among Fig. 1, under skewback (1), be provided with one and move supporting leg (2), divide into a horizontal rack frame (3) at mobile supporting leg again and connect together by loose-leaf with the skewback back.
Claims (1)
1, a kind of teaching inclined-plane teaching aid that can change the gradient arbitrarily, by the inclined-plane, movable supporting frame, tooth bar is formed, it is characterized in that: under skewback (1), be provided with one and move supporting leg (2), divide into a horizontal rack frame (3) at mobile supporting leg again and connect together by loose-leaf with the skewback back.
