Description
Technical field
The utility model belongs to teaching field, is specifically a kind of apparatus of physics teaching.
Background technology
, it is necessary to which the buoyancy that often checking CAS Institute of Physics is received is equal to the matter of physics liquid among the physical teaching course of junior-senior high school
Amount, all it is to measure discharge liquid and physical weight respectively among existing technology, it is very time-consuming and inconvenient.
The content of the invention
For the utility model in view of the above-mentioned problems, disclosing a kind of teaching aid, technical scheme is as follows：
A kind of teaching aid, including：
Transparent outer cover, described transparent outer cover are made up of clear glass, upper end open, and the lower end of transparent outer cover is funnel
Shape, bell mouth and is connected with test tube.
Storage tank, described storage tank upper end open, storage tank are connected with transparent outer cover by connecting pole, described water storage
Case preferably uses transparent material, and as glass is made, connecting pole is preferably glass, and storage tank, connecting pole, transparent outer cover are preferably integral
Chemical conversion type.
Spring scale, spring scale are connected by connecting line with transparent outer cover.
As an improvement, described test tube and the bell mouth of transparent outer cover lower end are threaded connection, test tube is demountable structure.
As an improvement, transparent outer cover upper end is provided with connecting hole, connecting hole is provided with connecting line, and connecting line and spring scale connect
Connect.
As an improvement, the top edge of storage tank is provided with drainage channel.
As an improvement, the outer wall of storage tank is provided with the rhone of vertical direction, under can make it that the water of draining is sufficient
Flow in test tube, increase accuracy.
The beneficial effects of the utility model are：
, can be with quick and convenient operation when verifying that buoyancy is equal to displaced weight, and can change in a short time more
Individual object, and water body outflow is not had, it is attractive in appearance to influence classroom.
