Description
Technical field
This utility model belongs to physics teaching equipment technical field, is specifically related to a kind of physics teaching experiment of in dined plane device。
Background technology
In existing physics teaching, need in many situations student is demonstrated, in order to Classroom theory knowledge combined with practice better。In mechanics teaching, during object analysis motion conditions in inclined plane, it usually needs the factor such as coefficient of friction and angle of inclination is considered wherein, recognizes physical phenomenon more intuitively for student, it is generally required to make student carry out direct vision by experiment。General way is by finding suitable place or utilizing teaching aid to complete this experimental teaching, but, find the suitable place used time long, and existing inclined-plane teaching aid takes up room greatly, not portable；On the other hand, even if the angle of inclination of skewback can regulate in existing inclined-plane teaching aid, but its coefficient of friction is also changeless, if desired coefficient of friction is changed, be accomplished by by multiple except coefficient of friction, all the other all identical inclined-plane teaching aids, but multiple inclined-planes teaching aid not only carries inconvenience, also need to when starting to test again inclined-plane teaching aid is set, student can not be allowed intuitively to understand under same tilt angle, object is moved the impact brought by coefficient of friction on inclined-plane, and efficiency of giving lessons is low。
Summary of the invention
The purpose of this utility model is in that to provide a kind of physics teaching experiment of in dined plane device, with the problem solving to propose in above-mentioned background technology。
To achieve these goals, this utility model is to realize by the following technical solutions: a kind of physics teaching experiment of in dined plane device, including base, swash plate guide rail, connect rope, angel measuring instrument, fixing bar, fixed iron piece, expansion link and pallet, the termination, right side of described base is connected by articulate with the termination, right side of swash plate guide rail, the left end top of described base is connected by expansion link is fixing with bottom the left end of swash plate guide rail, described angel measuring instrument is arranged on base by fixing screw, described fixed iron piece is arranged on swash plate guide rail by two fixing screws, the left arm of described angel measuring instrument is arranged between fixed iron piece and swash plate guide rail, and fixed iron piece is flexibly connected by adjusting bolt with swash plate guide rail, the termination, left side of described swash plate guide rail is provided with pulley, and swash plate guide rail is provided with slide block, the described right-hand member connecting rope is fixed on slide block, the left end connecting rope is fixed on pallet through pulley。
Preferably, described angel measuring instrument is provided with graduation mark。
Preferably, described expansion link is provided with adjusting bolt。
Preferably, described pulley is connected by fixing bar is fixing with the termination, left side of swash plate guide rail。
The beneficial effects of the utility model: this physics teaching experiment of in dined plane device, simple and reasonable, economical and practical, volume is little, be easy to carry, student can be allowed intuitively to understand under same tilt angle, object is moved the impact brought by coefficient of friction on inclined-plane, improves efficiency of giving lessons。
