Abstract

The invention provides a geometric body cross section demonstration device comprising a transparent geometric body container and a needle tube injector. One side of the geometric body container is provided with an air hole, and the opposite side is provided with a liquid inlet hole. The liquid inlet hole is internally provided with a protruding short conduit. The short conduit is flexibly connected with the injection port of the needle tube injector. Liquid is arranged in the needle tube injector. The liquid volume in the geometric body container is directly controlled by pushing and pulling the piston of the needle tube injector, and the liquid surface is enabled to present the shape of the cross section by changing the position and the angle of the geometric body container so that control is facilitated, the teaching efficiency can be enhanced, the liquid is absorbed out of the geometric body container into the needle tube injector after completion of teaching, and thus the device is easy to carry and is not liable to damage.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a geometrical body section demonstrator. Background technique [0002] Prior art: the air hole on one side of the geometric body is connected to an air bag through a hose, and the liquid inlet on the opposite side is connected to a solution bag containing a solution through a hose. Press the solution bag during teaching, the liquid enters the container through the hose, press the air bag to make the liquid flow back to the solution bag when changing other cross-sections, and adjust the liquid capacity to realize the cross-section change. [0003] Disadvantages: This method needs to adjust the air bag and solution bag back and forth to control the volume of liquid in the geometry, which is difficult to control and inconvenient to carry. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a direct and convenient geometry cross-section de...
