Abstract
The utility model relates to a flotation balance demonstration device, which is obvious in demonstration effect and simple in structure. The flotation balance demonstration device comprises a container, and is structurally characterized in that a hollow ball body is arranged inside the container, a flat panel is arranged on the hollow ball body, a fixing block used for fixing the hollow ball bodyis arranged under the flat panel, a dial scale with a plummet is arranged at the center position of the flat panel, and two sides of the dial scale are equipped with symmetrical trays.
Description
Technical field:
The utility model relates to a kind of buoyancy balance apparatus for demonstrating.
Background technology:
Middle school student do not have deep understanding usually to the buoyancy of the object in the physics teaching, and the more intuitive apparatus for demonstrating of needs is deepened the understanding to this notion.But at present, still there is not better to embody the pilot demonstration device of this respect.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of effect buoyancy balance apparatus for demonstrating obvious, simple in structure of demonstrating is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises container, its structural feature is provided with hollow ball in container, hollow ball is provided with flat board, dull and stereotyped below is provided with the fixed block that is used for fixing hollow ball, and the center of flat board is provided with the index dial with plumb bob, and the index dial both sides are provided with symmetrical pallet.
The beneficial effects of the utility model:
1, good demonstration effect:
By device of the present utility model, can observe object intuitively and have buoyancy, effect is obvious, helps to improve the quality of teaching;
2, simple in structure:
Assembly of the present utility model is few, and simple in structure, is easy to make, and is easy to popularize.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises container 1, in container 1, be provided with hollow ball 2, hollow ball 2 is provided with dull and stereotyped 4, dull and stereotyped 4 belows are provided with the fixed block 3 that is used for fixing hollow ball 2, dull and stereotyped 4 center is provided with the index dial 7 with plumb bob 8, and index dial 7 both sides are provided with symmetrical pallet 5.
During use, at first counterweight 6 is placed in the pallet 5, again determinand 9 is placed in another pallet 5, add and subtract counterweight 6 then and make two pallets, 5 levels; Can illustrate that the utility model can utilize balance to come the Measuring Object quality, also can intuitively significantly observe the buoyancy of object.
