Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of buoyancy demonstration teaching aid, including casing 1, rotating shaft 2, beaker 3, pulley A4, outlet 5, switch 6, water inlet 7, buoyant spheres 8, electronics tension tester 9, nylon rope 10, pulley B11, cantilever 12 and support bar 13; Being provided with a rotating shaft 2 on the left of described casing 1, the surface of the rotating handles of rotating shaft 2 is matsurface, it is prevented that skid; Described rotating shaft 2 is wound with nylon rope 10; Described nylon rope 10 is through pulley B11; Described pulley B11 is arranged on cantilever 12 both sides, and described cantilever 12 is arranged on support bar 13; On the casing 1 that described support bar 13 is fixing; Described nylon rope 10 is connected on electronics tension tester 9; Described electronics tension tester 9 surface is provided with display screen, and for showing the size of pulling force, lower end is connected to nylon rope 10 equally; Described nylon rope 10 is walked around pulley A4 and is connected in buoyant spheres 8; Described pulley A4 is fixed on beaker 3; Described beaker 3 is fixed on bottom casing 1, and beaker 3 is provided with outlet 5 and water inlet 7, outlet 5 and water inlet 7 and all stretches out outside casing 1; Described outlet 5 end is provided with switch 6, is used for shutting and open outlet 5; Described water inlet 7 place of adding water is funnel-form, facilitates operator to add water.
Operation principle of the present utility model is: after Preparatory work of experiment is ready, rotating shaft 2, nylon rope 10 can be wrapped in rotating shaft 2, thus pulling buoyant spheres 8, the buoyant spheres 8 made enters in water, between in completely into water, on electronics tension tester 9, the numerical value of display can become big gradually, after during buoyant spheres 8 is completely into water, buoyant spheres 8 continues to decline, and on electronics tension tester 9, the numerical value of display will not change.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
