Description
Technical field
The utility model relates to a kind of Physical Experiment apparatus for demonstrating, particularly relates to a kind of simple and easy kinetic force of friction apparatus for demonstrating.
Background technology
Friction force is divided into kinetic force of friction and stiction, and in Physical Experiment presentation process, namely a kind of Physical Experiment apparatus for demonstrating is needs, and it can facilitate and show physical meaning intuitively, and learner is more easily learnt.For more existing all more single about friction force demonstration device, be merely able to the measurement single body structure surface being carried out to friction force, although accurate stressed size can be obtained, the difference of different surfaces structure can not be showed intuitively.
Utility model content
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of simple and easy kinetic force of friction apparatus for demonstrating, comprise device body, frictional groove, slide block, spring, push pedal, starting switch, end cap, it is characterized in that, described frictional groove is the sliding rail on device body described in, described slide block is placed in described frictional groove, described spring is arranged in the ends packet of described device body, described spring one end is fixed on inside the ends packet of described device body, the other end is fixed in described push pedal, described device body is also provided with the described starting switch controlling described push pedal movement, structure is a taper bolt shape, described starting switch is arranged on outside the end of described device body, the displacement of described push pedal is limited by spacing hole, the end of described device body is also provided with described end cap.
Further, described frictional groove for being disposed side by side on described device body, and has the structure of differentiated friction plane, and groove end position is in the inner side of described push pedal.
Further, described push pedal is the rectangle platy structure of two end band grooves, matches with the convex structure of the ends packet upper and lower side of described device body, makes described push pedal move forward and backward under force.
The good effect that the utility model has is:
The utility model structure is simple, processing and fabricating is convenient, is slided in orbit, judged the size of friction force by moved distance by the stressed promotion slide block of push pedal, the size of the friction force of different surfaces structure can be shown intuitively, there is good demonstrating effect.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.

Wherein, 1, balancing weight, 2, rotor wheel, 3, pull bar, 4, spring, 5, load, 6, axle sleeve, 7, cross bar.
Embodiment
In order to make the utility model object, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is one of the present utility model simple and easy kinetic force of friction apparatus for demonstrating structural representation.
A kind of simple and easy kinetic force of friction apparatus for demonstrating, comprise device body 1, frictional groove 2, slide block 3, spring 4, push pedal 5, starting switch 6, end cap 7, it is characterized in that, frictional groove 2 is the sliding rail on a device body 1, slide block 3 is placed in described frictional groove 2, spring 4 is arranged in the ends packet of device body 1, spring 4 one end is fixed on inside the ends packet of device body 1, the other end is fixed in push pedal 5, device body 1 is also provided with the described starting switch 6 controlling push pedal 5 movement, structure is a taper bolt shape, starting switch 6 is arranged on outside the end of device body 1, the end of device body 1 is also provided with end cap 7.
Wherein, frictional groove 2 for being disposed side by side on device body 1, and has the structure of differentiated friction plane, and groove end position is in the inner side of push pedal 5.
Wherein, push pedal 5 is the rectangle platy structure of two end band grooves, matches with the convex structure of the ends packet upper and lower side of device body 1, makes push pedal 5 move forward and backward under force.
In presentation process, first push pedal 5 is moved to the position of starting switch 6, now, be subject to the thrust of spring 4, starting switch 6 blocks push pedal 5, end cap 7 covers in the ends packet of device body 1, box body size just push pedal 5 is in the position of stress, then the flat board of different surfaces structure is put in frictional groove 2, again slide block 3 is distributed on the position near push pedal 5, finally, unclamp starting switch 6 and make that push pedal 5 is stressed to be moved forward, apply a same acceleration to each slide block 3 simultaneously, continue afterwards to move forward a segment distance under the effect of inertia force, but because the surfaceness of unlike material is different, the position that slide block 3 stops also is different, the position that logical slide block 3 finally stops, the size of the force of sliding friction in demonstrated different materials face can be shown intuitively.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
