Abstract
The utility model belongs to the technical field of physics, concretely relates to automatic ware of demonstrating of frictional force. This automatic ware of demonstrating of frictional force, including slide, slider and magnetic board, be equipped with support and magnetic board on the slide, but the support ski slide, support one side is equipped with the slider, is equipped with the multiunit assembly pulley on the support, and the winding has the driving rope between each assembly pulley, and driving rope one end is connected with the slider, and one end is equipped with the magnet piece in addition, and the magnet piece is located the magnetic board. The beneficial effects are that: the utility model relates to an automatic ware of demonstrating of frictional force can abluent reflection frictional force change rule directly perceived, and can remain the demonstration data, be convenient for the audio -visual study of student with understand the knowledge that frictional force was correlated with.
Description
Technical field
The utility model belongs to physics technology field, is specifically related to a kind of friction force automatic demonstrating device.
Background technology
At present, existing friction force demonstration device intelligence is single, carry out friction force demonstration qualitatively, and can not preserve experimental data, is not easy to student and learns the knowledge relevant with understanding friction force intuitively.
Utility model content
The utility model is in order to make up the defect of prior art, and providing one can show change in friction force image intuitively, comprehensively, clearly, and the friction force automatic demonstrating device can preserved friction force experimental data process.
The utility model is achieved by the following technical solution:
A kind of friction force automatic demonstrating device, comprise slide plate, slide block and magnetic plate, described slide plate is provided with support and magnetic plate, support can in the enterprising line slip of slide plate, and described support side is provided with slide block, and support is provided with organizes pulley blocks more, transmission rope is wound with between each pulley blocks, transmission rope one end is connected with slide block, and one end is provided with magnet piece in addition, and magnet piece is positioned on magnetic plate.
Further, described pedestal upper end and lower end are respectively provided with one group of pulley blocks, and pulley blocks one end that pedestal lower end walked around by transmission rope is connected with slide block.
Further, described transmission rope is connected by spring with between slide block.
The beneficial effects of the utility model are: the reflection change in friction force rule that a kind of friction force automatic demonstrating of the utility model device can intuitively clean, and can retain demonstration data, are convenient to student and learn the knowledge relevant with understanding friction force intuitively.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1 slide plate, 2 slide blocks, 3 springs, 4 transmission ropes, 5 supports, 6 magnet pieces, 7 magnetic plates, 8 pulley blockss.
