Abstract
The utility model relates to a teaching and demonstration apparatus, in particular to an apparatus for teaching and demonstrating the law of Archimedes. The apparatus for teaching and demonstrating the law of Archimedes has a simple structure and can measure the buoyancy force applied on an object. The apparatus comprises an iron support. The structure of the apparatus has the following characteristics: a measuring cup is arranged on the iron support, a mouth of a glass bottle is fixed by an iron clamp of a supporting rod of the iron support, a conduit which is communicated with the measuring cup and the glass bottle is arranged on a rubber cork in the mouth, and the upper end of the glass bottle is open.
Description
Technical field:
The utility model relates to a kind of teaching demonstration device, more particularly, relates to a kind of teaching demonstration device of Archimedes' principle.
Background technology:
Archimedes' principle in the physics of middle school is meant that the object (all or part of) that is immersed in the fluid is subjected to buoyancy upwards, and its size equals the gravity of fluid that object arranges.But, the demonstration instrument that in present classroom instruction, is adopted, mostly complex structure, intuitive are good inadequately, are unfavorable for the understanding of student to law, cause teaching efficiency undesirable.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of Archimedes' principle teaching demonstration device of simple in structure, the suffered buoyancy of energy measurement object is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises iron stand, its structural feature is that iron stand is provided with measuring cup, on the iron clamp of iron stand pole, be fixed with the bottleneck of vial, the plug of bottle mouth position is provided with the conduit that is communicated with measuring cup and vial, and the top of vial is uncovered.
The beneficial effects of the utility model:
1, simple in structure:
Because the utility model iron stand is provided with measuring cup, is fixed with the bottleneck of vial on the iron clamp of iron stand pole, the plug of bottle mouth position is provided with the conduit that is communicated with measuring cup and vial, and the top of vial is uncovered; So, of the present utility model simple in structure;
2, the suffered buoyancy of energy measurement object:
Put into object in the vial of the utility model device, the water of discharge imports measuring cup, can draw the volume that object arranges water, and then the weight of water, the i.e. size of the suffered buoyancy of object as can be known.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises iron stand 1, and iron stand 1 is provided with measuring cup 2, is fixed with the bottleneck 5 of vial 7 on the iron clamp 6 of iron stand 1 pole 9, and the plug 4 at bottleneck 5 places is provided with the conduit 3 that is communicated with measuring cup 2 and vial 7, and the top of vial 7 is uncovered.
A presentation process below in conjunction with description of drawings the utility model device:
At first, inject water in vial 7, the water surface and conduit 3 mouths of pipe 8 maintain an equal level in vial 7; The object that does not absorb water is put into vial 7, and the water that is arranged by object flows into measuring cup 2 via conduit 3; Numerical value by measuring cup 2 demonstrates can draw the volume and weight that is arranged water by object, therefore, can learn the size of the buoyancy of object according to Archimedes' principle.Promptly finish presentation process one time.
