Abstract
The utility model relates to teaching aids, in particular to a demonstration teaching aid for mechanics teaching. The bottom end of a vertical post is rested upright on a base, and the top end of the vertical post is hinged to a midpoint of a swing lever. A sleeve is fixedly connected to one end of a beam and is sleeved on the vertical post. A spring scale is hung between a slide carriage c at the other end of the beam and a slide carriage a at one end of the swing lever. A slide carriage b is arranged at the other end of the swing lever. The demonstration teaching aid for mechanics teaching is capable of expressing the lever principle effectively, allows students to accept the lever principle easily, makes the explanations by teachers easier, is simple in structure, simple to operate, low in cost and suitable for wide application, enables teaching quality to be improved, and makes students more enthusiastic in studying.
Description
Technical field
The utility model relates to the teaching appurtenance, relates in particular to a kind of mechanics teaching demonstration teaching aid.
Background technology
In the physics teaching course, mechanics is ingredient important in the physics course, the aided education apparatus demonstration that experimentizes by experiment in the process of giving lessons, can be understood and grasp many principles of mechanics more intuitively by the student, lever principle etc. for example, present this assistant experiment apparatus extremely lacks, be to draw static synoptic diagram by the teacher at blackboard to explain in more giving lessons, this figure demonstrating student is not dark to its impression, especially in the size of lever principle power, when direction and application point, apparatus can make student's fast understanding easily and it is had deep impression more by experiment.
Summary of the invention
The utility model is intended at the deficiency that exists in the background technology, and a kind of mechanics teaching demonstration teaching aid that provides.
Mechanics teaching demonstration teaching aid of the present utility model, be to be constituted by base, column and rocking lever, stand in the bottom of column be fixed on the base, top and rocking lever in point articulated, crossbeam one end affixed sleeve and being socketed on the column, the other end of crossbeam is provided with between the slide a that an end of slide c and rocking lever is provided with and is articulating spring balance; The other end of rocking lever is provided with slide b.
As further improvement of the utility model, rocking lever is provided with scale a, crossbeam is provided with scale b.
As further improvement of the utility model, be equipped with locking device on sleeve, slide a, slide b and the slide c.
A kind of mechanics teaching demonstration teaching aid of the present utility model, principle that can the effectively expressing lever, the student is acceptant, has reduced the difficulty of teacher's explanation, and rational in infrastructure, simple to operate, cost is low, suitable for large-scale promotion popularizing promoted quality of instruction, increased student's learning enthusiasm.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
, be described further a kind of mechanics teaching demonstration teaching aid of the present utility model below in conjunction with Fig. 1.
