Description
Technical field
The utility model is related to a kind of teaching aid, is specifically a kind of atmospheric pressure demonstration teaching aid.
Background technology
Atmospheric pressure is a kind of invisible, impalpable gas, although we just live in an atmosphere, but is difficult to experience
The presence of air, particularly in teaching, due to lacking teaching aid, it is difficult to students experience is made to the presence of atmospheric pressure, therefore vast
Middle School Physics circle teachers and students the teaching aid of atmospheric pressure is present greatly expects and require.
Content of the invention
The purpose of this utility model is just to provide a kind of atmospheric pressure teaching aid, in order to object teaching, meets vast middle school
The teaching demand of physics circle teachers and students.
Scheme of the present utility model includes pumping type atmospheric pressure demonstration teaching aid and exempts from pumping type atmospheric pressure demonstration teaching aid,
Pumping type atmospheric pressure demonstration teaching aid is made up of base, cylindrical tube, and described base is the box body of a square supreme lid,
Cylindrical tube is provided with the middle part of box body, and cylindrical tube is adhesively fixed in the cassette bottom in the middle part of square case, cylindrical tube
The bottom of body is provided with six little triangular reinforced plates, and little triangular reinforced plate is adhesively fixed on the circumference at cylindrical tube bottom, with
Reinforce the intensity of cylindrical tube.The lower end of cylindrical tube is provided with the two square wickets in left and right, in order to connect inside and outside cylinder
Liquid, the top of cylindrical tube are provided with connecting tube, and the bottom of connecting tube is integrated with cylindrical tube sealing, connecting tube upper
End is provided with check valve, and check valve is provided with exhaust tube, exhaust tube by the upper end being threadedly coupled installed in connecting tube, the upper end of check valve
Lower end aspiration pump is housed, the left end of box body is provided with water supply hose, and the left end connection of water supply hose is entered on feed cock
The right-hand member of water tube hose is inserted in foursquare box body.During test, feed cock is opened, the water in tap enters box by water supply hose
In vivo, then open pumping switch pump, extract the air in cylinder out, the water level in cylinder will be gradually increasing, when water level is near top
During portion, aspiration pump is closed, the water level in cylinder will be still in the water level after rising, and test proves the presence of atmospheric pressure,
And demonstrate the visual effect of atmospheric pressure.
The utility model simple structure, easy to operate, make simply, demonstrating effect is obvious.
It is described in further detail below in conjunction with the accompanying drawings.
