Description
Technical field
This utility model relates to a kind of inclined plane demonstrator for Physical Experiment, including base plate and demonstration board, base plate and the gemel connection of demonstration board, base plate nearly hinge end side surface is connected protractor, the upper surface of base plate is tilting, connected one end of elevating lever by revolute pair, the elevating lever other end is connected with demonstration board bottom surface.
Background technology
In existing physics teaching, need in the case of many student is demonstrated, so that preferably Classroom theory knowledge being combined with practice, and currently there are no and fairly perfect demonstration teaching aid occurs to demonstrate the various physical phenomenons produced on inclined-plane about object, such as the frictional force of object, movement velocity etc..Teacher recognizes physical phenomenon more intuitively when student carries out inclined-plane teaching for student at present, it is generally required to make student intuitively observe by experiment, general way is by finding suitable place or finding different teaching aids and be combined into and have the apparatus of demonstration inclined-plane function, so in experimental demonstration teaching process, not only need to spend the longer time to find suitable apparatus or place, and the apparatus of this combination is not fixed easily due to bevel angle, easily failure in presentation process, the most not only have impact on quality of instruction, but also reduce teaching efficiency.
Utility model content
The purpose of this utility model is to provide a kind of inclined plane demonstrator for Physical Experiment, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: for the inclined plane demonstrator of Physical Experiment, including base plate and demonstration board, base plate and the gemel connection of demonstration board, base plate nearly hinge end side surface is connected protractor, the upper surface of base plate is tilting, one end of elevating lever is connected by revolute pair, the elevating lever other end is connected with demonstration board bottom surface, and demonstration board bottom surface is provided with receives thing groove, receives and is provided with track in thing groove, connection sliding block on track, slide block is hinged with elevating lever, and rotary shaft baffle plate frame is passed through in the upper surface at the nearly hinge of demonstration board, is provided with horizon rule in baffle plate frame.
Preferably, clamping billiards in described baffle plate frame, billiards is just to crash sensor.
Preferably, described demonstration board side is provided with scale.
Compared with prior art, the beneficial effects of the utility model are: this utility model utilizes elevating lever to adjust the angle of inclination of demonstration board, it is easy to bevel angle regulates, and not only increases quality of instruction, also improves teaching efficiency, and also can demonstrate collision experiment.Additionally this utility model also has simple in construction, advantage easy to use.
