Abstract
The utility model provides a ware is demonstrated on inclined plane for physical teaching, relate to physical teaching equipment and facility, including the inclined plane, the demonstration ball, pivot and base, the base is connected through big pivot with the inclined plane, the base is connected through the pivot with slope pole B one end, the slope pole B other end is connected through the pivot with the fixed plate, the angle on inclined plane can be changed through slope pole A and slope pole B, make experiment convenience more, can place slope pole B standing groove with the pole B that inclines when not using in, place corresponding inslot through the part with other, the messenger carries convenience more, through changing the friction surface, obtain the velocity of movement of different faces, it is more convenient with the use to make the measurement, through the speed measurement ware can be accurate measure the demonstration ball the velocity of movement, and at the enterprising line display of display screen, the error of bringing has been avoided testing, to sum up bring a lot of convenience for the user.
Description
technical field:
The utility model relates to physics teaching equipment and facilities, is specifically related to a kind of physics teaching inclined plane demonstrator.
background technology:
In existing physics teaching, many situation Students 's are demonstrated, so that better Classroom theory knowledge is combined with practice, and also there are not the various physical phenomenons that fairly perfect demonstration teaching aid produces on inclined-plane to demonstrate object of interest now, as the friction force, movement velocity etc. of object.Current teacher carries out time teaching in inclined-plane in order to student is familiar with physical phenomenon more intuitively student, generally need to make student carry out direct vision by experiment, general way is combined into has the demonstration tiltedly apparatus of function by finding suitable place or finding different teaching aids, like this 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 easily fixed due to bevel angle, easily failure in presentation process, so not only have impact on mathematical quality, but also reduce efficiency of teaching, in order to solve the problems of the technologies described above, a kind of new technical scheme of special proposition.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of physics teaching inclined plane demonstrator, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of physics teaching inclined plane demonstrator, comprise dip plane, demonstration ball, rotating shaft and base, base is connected by large rotating shaft with dip plane, base is connected by rotating shaft with tilting bar B one end, the tilting bar B other end is connected by rotating shaft with fixed head, tilting bar B is provided with fixture block, fixture block contacts with tilting bar A one end, the tilting bar A other end is connected by rotating shaft with base, base is provided with tilting bar B standing groove, described dip plane is provided with baffle plate fixed block, baffle plate fixed block inside is provided with baffle plate, demonstration ball is provided with on the left of baffle plate fixed block, dip plane is provided with rubbing surface standing groove, dip plane is connected with demonstration ball collection box, demonstration ball collection box top is provided with display screen, display screen is connected by wire with velocity meter.
Described demonstration ball can be ball or rectangular parallelepiped.
The beneficial effects of the utility model are: the angle that can be changed dip plane by tilting bar A and tilting bar B, make experiment more convenient, tilting bar B can be placed in tilting bar B standing groove when not using, by other parts are placed in corresponding groove, it is more convenient to make to carry, by changing rubbing surface, obtain the movement velocity of not coplanar, make measurement and use convenient, Negotiation speed measuring appliance can measure the movement velocity of demonstration ball accurately, and show on a display screen, avoid the error that experiment brings, a lot of convenience is brought in sum to user.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
embodiment:
With reference to accompanying drawing, a kind of physics teaching inclined plane demonstrator, comprise dip plane 1, demonstration ball 2, rotating shaft 5 and base 10, base 10 is connected by large rotating shaft 12 with dip plane 1, base 10 is connected by rotating shaft 5 with tilting bar B16 one end, the tilting bar B16 other end is connected by rotating shaft 5 with fixed head 6, tilting bar B16 is provided with fixture block 15, fixture block 15 contacts with tilting bar A7 one end, the tilting bar A7 other end is connected by rotating shaft 5 with base 10, base 10 is provided with tilting bar B standing groove 9, described dip plane 1 is provided with baffle plate fixed block 4, baffle plate fixed block 4 inside is provided with baffle plate 3, demonstration ball 2 is provided with on the left of baffle plate fixed block 4, dip plane 1 is provided with rubbing surface standing groove 8, dip plane 1 is connected with demonstration ball collection box 14, demonstration ball collection box 14 top is provided with display screen 13, display screen 13 is connected by wire with velocity meter 11.Described demonstration ball 2 can be ball or rectangular parallelepiped.The angle of dip plane 1 can be changed by tilting bar A7 and tilting bar B16, make experiment more convenient, tilting bar B16 can be placed in tilting bar B standing groove 9 when not using, by other parts are placed in corresponding groove, it is more convenient to make to carry, by changing rubbing surface, obtain the movement velocity of not coplanar, make measurement and use convenient, Negotiation speed measuring appliance 11 can measure the movement velocity of demonstration ball 2 accurately, and show on display screen 13, avoid the error that experiment brings, a lot of convenience is brought in sum to user.
