Description
Technical field
The utility model relates to physics facility, is specifically related to a kind of for probing into the physics facility that affects force of sliding friction size factor.
Background technology
Many laws of physics only have by experiment introduces, derives and verifies, just can make more deep, the vivid understanding of student, for example probe into that to affect force of sliding friction size factor be an important experimental courses in physics teaching, existing experimental provision is also very simple, be only to prepare the plank of several different degree of roughness, then experience with the wooden unit that hand drags Different Weight.
This traditional experimental provision, uses very inconveniently, and human factor impact is very large, makes teaching process underaction, and inconvenient Students ' Learning and understanding, need further improvement.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of it is rational in infrastructure, easy to use for probing into the physics facility that affects force of sliding friction size factor, thereby eliminates defect in above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of for probing into the physics facility that affects force of sliding friction size factor, comprise the first slide rail and the second slide rail that be arranged in parallel side by side, the upper surface of described the first slide rail and the second slide rail is provided with to clamp the grip nut of plank, the end of described the first slide rail and the second slide rail is provided with block, on described block, offer and described the first slide rail and the second slide rail through hole one to one, in described through hole, all slide and wear a draught line;
Also comprise the first slide block and the second slide block, the corresponding activity of described the first slide block and the second slide block is positioned on the plank of described the first slide rail and the second slide rail upper surface, the traction end of described the first slide block and the second slide block is provided with spring tension meter, and described spring tension meter connects with corresponding draught line;
The end of described the first slide rail and the second slide rail be also installed with the to reel capstan winch of described draught line, one end of described capstan winch has handle.
In the utility model, the base of described capstan winch is fixedly connected with the second slide rail with described the first slide rail.
In the utility model, the upper surface of described the first slide block and the second slide block all offers to install the groove of counterweight.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model is arranged with two guide rails side by side in parallel, and the capstan winch of the described draught line that is provided with in the end of guide rail to reel, utilize draught line to affect wooden unit to slide, based on this structure, can guarantee that two wooden units have identical haulage speed, draw thereby can effectively contrast the experiment conclusion that affects force of sliding friction size factor.
The utility model is provided with to clamp the grip nut of plank, conveniently the plank of different degree of roughness is changed, and improves the convenience of experiment.
The upper surface of the utility model the first slide block and the second slide block all offers to install the groove of counterweight, and the convenient counterweight of installing, to probe into the impact of mass of object on force of sliding friction size.
In sum, the utility model is rational in infrastructure, easy to operate, has improved the convenience of teaching, by contrast, can draw intuitively experiment conclusion, facilitates student's understanding.
