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
The present invention relates to a kind of teaching aid, more particularly to a kind of solid section demonstration device.
Background technology
Prior art：Stomata in solid side an airbag by soft pipe connection, and a solution bag equipped with solution is connected to by flexible pipe at relative opposite side inlet.Solution bag is pressed during teaching, liquid is entered in container by flexible pipe, airbag is pressed when converting other sections makes liquid flow return solution bag, and regulation liquid capacity realizes Transformed area.
Shortcoming：This method needs to adjust the volume of airbag and solution bag to control liquid in solid back and forth, is difficult to control, it has not been convenient to carry.
The content of the invention
The technical problems to be solved by the invention are directed to the deficiencies in the prior art, there is provided a kind of direct easily solid section demonstration device.
The technical problems to be solved by the invention are realized by following technical scheme.The present invention is a kind of solid section demonstration device, is characterized in：Including solid container, syringe, the side of the solid container is provided with stomata, and opposite side is provided with a prominent tubulature, and the syringe is flexibly connected built with liquid, the injection port of syringe with tubulature.
The technical problems to be solved by the invention can also further be realized by following technical scheme.A kind of above-described solid section demonstration device, its further preferred technical scheme is：The solid is square, cuboid, cylinder, conically shaped body.
The technical problems to be solved by the invention can also further be realized by following technical scheme.A kind of above-described solid section demonstration device, its further preferred technical scheme is：The solid container is made using transparent acrylic material, and the liquid is colored liquid.
The technical problems to be solved by the invention can also further be realized by following technical scheme.A kind of above-described solid section demonstration device, its further preferred technical scheme is：The tubulature internal orifice dimension is engaged with the injection port external diameter of syringe.
The technical problems to be solved by the invention can also further be realized by following technical scheme.A kind of above-described solid section demonstration device, its further preferred technical scheme is：1/2 of liquid volume not less than solid container volume in syringe.
Compared with prior art, the present invention directly controls the liquid volume in solid container due to the piston by push-and-pull syringe, position and angle by transformation geometry body container, liquid surface is set to show cross sectional shape, it is easy to control, improves efficiency of teaching, from solid container is all drawn onto in syringe liquid after terminating by teaching, beneficial to carrying, it is hardly damaged.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the invention.
Specific embodiment
Referring to the drawings, concrete technical scheme of the invention is further described, the present invention is further understood that in order to those skilled in the art, without constituting the limitation to its right.
Reference picture 1, a kind of solid section demonstration device, it is characterised in that：Including transparent solid container 1, syringe 2, the side of the solid container is provided with stomata 5, relative opposite side is provided with a prominent tubulature 3, and the tubulature is flexibly connected with the injection port of syringe, and the syringe is built with colored liquid 4.
The solid can be square, cuboid, cylinder, conically shaped body etc., the cross sectional shape of observable difference solid.
The solid container is made using transparent acrylic material, and the liquid is colored liquid.
The tubulature internal orifice dimension is engaged with the injection port external diameter of syringe, prevents liquid from oozing out.
1/2 of liquid volume not less than solid container volume in the syringe.
During teaching, the position of transparent hollow square is first adjusted, by the injection port insertion tubulature of syringe, injected liquid into square, solution water plane can show sectional view.To conversion sectional view, square body position need to be only adjusted, the piston of push-and-pull syringe adjusts amount of solution.
