Abstract
The utility model provides an inclined plane demonstration device used for physics teaching. The inclined plane demonstration device comprises a base plate, an inclined plate seat connected with the base plate through a hinged shaft, and an inclined plate connected with the inclined plate seat. An included angle is formed between the inclined plate and the base plate through the inclined plate seat. An angle measuring instrument is connected to the hinged shaft ends of the base plate and the inclined plate seat. A telescopic rod is arranged between the base plate and the inclined plate. A baffle plate, close to the connecting part between the inclined plate seat and the inclined plate, is perpendicularly arranged on the inclined plate seat. The inclined plate comprises more than two inclined plate units which are identical in structure but different in friction coefficient. Adjacent inclined plate units are stacked in a movable and parallel manner. The inclined plate seat is provided with a timer. The inclined plane demonstration device is simple in structure, and the influence of different inclination angles to the movement situation of objects with an identical friction coefficient or the influence of different friction coefficients to the movement situation of objects with an identical inclination angle can be observed; in addition, by adopting the timer, students can better understand the influences of the friction coefficient and the inclination angle to the inclined plate movement of the objects in the experiment.
Description
Technical field
The utility model relates to a kind of physical teaching aid, specifically a kind of inclined plane demonstrating device for physics teaching.
Background technology
In existing physics teaching, in many situations, need student to demonstrate, so that better Classroom theory knowledge is combined with practice.In mechanics teaching, during the motion conditions of object analysis on dip plane, conventionally the factors such as friction factor and angle of inclination need to be considered wherein, for student is familiar with physical phenomenon more intuitively, generally need to make by experiment student intuitively observe.General way is by finding suitable place or utilizing teaching aid to complete this experimental teaching, still, find the suitable place used time long, and existing inclined-plane teaching aid takes up room greatly, not portable; On the other hand, even the angle of inclination of skewback can regulate in existing inclined-plane teaching aid, but its friction factor is also changeless, if desired change friction factor, just need to by a plurality of except friction factor, all the other all identical inclined-plane teaching aids, but a plurality of inclined-planes teaching aid not only carries inconvenience, while starting to test, also need again inclined-plane teaching aid to be set, can not allow intuitively the impact that student understands under same tilt angle, friction factor moves and brings on inclined-plane object, the efficiency of giving lessons is low.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides that a kind of student of convenience observes under same tilt angle intuitively, friction factor difference makes the different inclined plane demonstrating device for physics teaching of the motion conditions of object on inclined-plane.
The utility model solves the technical scheme that its technical matters adopts:
A kind of inclined plane demonstrating device for physics teaching, comprise base plate, the swash plate seat being connected by jointed shaft with the end of base plate, and be connected to the swash plate of swash plate seat end, by swash plate seat, between swash plate and base plate, form angle, and the hinged axle head of base plate and swash plate seat is connected with angel measuring instrument, between the upper surface of base plate and the lower surface of swash plate, be provided with expansion link, junction near swash plate seat and swash plate, on swash plate seat, be vertically provided with baffle plate, described swash plate comprises that two above structures are identical, the swash plate unit that friction factor is different, movable parallel stacking between adjacent swash plate unit, on described swash plate seat, be provided with timer, and the starting switch of timer is arranged on swash plate, terminating switch is arranged on baffle plate.
Between two above swash plate unit that structure is identical, friction factor is different, by bolt, be flexibly connected, and be connected to one between the swash plate unit of bottommost and swash plate seat.
Described expansion link comprises threaded line pipe and threaded rod.
Compared with prior art, the beneficial effect producing is a kind of inclined plane demonstrating device for physics teaching of the present utility model:
The utility model is simple in structure, can observe that friction factor is identical, the different impacts that the motion conditions of object is caused in angle of inclination; Also can observe that angle of inclination is identical, the different impacts that the motion conditions of object is caused of friction factor; In experimentation, the starting switch of timer is arranged on to the homeposition of object, terminating switch is arranged on baffle plate, by timer, can make student understand better the impact that cause in swash plate motion object at friction factor and angle of inclination.
