Ability, the ability independently analyzed problems and solved them and realistic scientism, creativity consciousness and creativity；Together
When also enable student by good technology awareness education.The experiment teaching aid unicity used at present in physics teaching is strong, often
A kind of teaching aid can only demonstrate a kind of physical phenomenon, and still, each test much all communicates in physics, can pass through a reality
Test and multiple knowledge points in physics are clearly demonstrated, so as to increase cognition and understanding of the student to knowledge point.
Utility model content
Based on the problem of teaching aid function is single in physics teaching, the purpose of this utility model is to provide a kind of pulley and floated
The Multifunctional demonstration device of power.
The purpose of this utility model is mainly realized by following technical scheme.
A kind of Multifunctional demonstration device of pulley and buoyancy, it includes：Framework, fixed pulley, movable pulley, magnet piece, counterweight
Block, spring scale and container cup, the framework are made up of cross member, left side vertical beam and entablature, for entering to whole apparatus for demonstrating
Row support, the fixed pulley and movable pulley are individually or in a manner of combination, to pass through the multiple upper horizontal strokes installed in framework of magnet piece
On beam lower surface, fixed pulley and movable pulley is fixed on the optional position of frame upper beam, being demonstrated during for testing,
The balancing weight is cylindrical type, and weight is certain, installed in the lower end of the assembly pulley of fixed pulley, movable pulley or composition, and is passed through
Spring scale carries out reading to it, and the container cup is built with water, for providing buoyancy to balancing weight.
Preferably, scale be present on the entablature of the framework, for being labeled to the position of magnet piece, so that student
Fixed pulley and movable pulley stress and the relation of rope angulation can intuitively be recognized.
Preferably, scale is labeled with the balancing weight and container cup, for immersing the volume of container cup to balancing weight, and
The volume that water rises in container cup carries out reading.
It is further preferred that the volume for not having the volume for loading water to be less than balancing weight on the container cup, prevents from being drilled
When showing, the spilling of water is caused.
Compared with prior art, a kind of beneficial effect of the Multifunctional demonstration device of pulley and buoyancy of the present utility model exists
In：
By the structure composition of the pulley and the Multifunctional demonstration device of buoyancy, a kind of teaching aid can be used intuitively right
The knowledge point of physics middle pulley and buoyancy is demonstrated, and is deepened understanding of the student to the two knowledge points, is made student consciousness to thing
The interlinking between knowledge is managed, increases the learning interest of student, expands the thinking of student, improves efficiency of teaching.
