Abstract
The utility model relates to a teaching appliance for simulating the working principle of a water pump. The teaching appliance comprises a handle, a rubber plug, a water-pumping tube main body, a water outlet tube and a copper sheet, wherein the handle is connected with the rubber plug by means of joggle joint; the rubber plug is movably connected to the inner cavity of the water-pumping tube main body; the water outlet tube is fixedly connected to the water-pumping tube main body; and the copper sheet is connected to one end of the rubber plug via a hinge. The teaching appliance disclosed by the utility model is convenient to carry, simple and practical, resource-saving, and more direct in demonstration effect.
Description
Technical field
The utility model relates to a kind of realia, particularly a kind of Simulated Water pump work theory teaching utensil.
Background technology
About atmospheric teaching appliance more complicated all, carry trouble on the classroom, the demonstration effect is not direct yet, also be form explanation by oral account for the explanation of the principle of work of water pump, can not observe intuitively, student's major part all is only to know reason, and does not meet material object.
The utility model content
The utility model is primarily aimed at above problem, provides a kind of easy to carry, simple and practical, saves resource, and the demonstration effect is teaching appliance more directly, and its technical scheme is as follows:
A kind of Simulated Water pump work theory teaching utensil comprises: handle, rubber stopper, drinking-water pipe main body, rising pipe and copper sheet, described handle is connected with rubber stopper by the mode of joggle, rubber stopper moves and is connected in drinking-water pipe main body inner chamber, rising pipe is fixed in the drinking-water pipe main body, and copper sheet is connected in rubber stopper one end by hinge.
On the technique scheme basis, described copper sheet can only folk prescription to activity.
On the technique scheme basis, described rising pipe is installed on drinking-water pipe main body upper end.
On the technique scheme basis, described drinking-water pipe body shape is square.
The beneficial effect that the utility model produces has: easy to carry, simple and practical, save resource, and the demonstration effect is more direct.
Description of drawings
Fig. 1, Fig. 2: structural representation of the present utility model and part block diagram;
Symbol description:
1. handle, 2. rising pipe, 3. rubber stopper, 4. drinking-water pipe main body, 5. copper sheet.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
As shown in Figure 1 and Figure 2, a kind of Simulated Water pump work theory teaching utensil, it is characterized in that, comprise: handle 1, rubber stopper 3, drinking-water pipe main body 4, rising pipe 2 and copper sheet 5, described handle 1 is connected with rubber stopper 3 by the mode of joggle, rubber stopper 3 moves and is connected in drinking-water pipe main body 4 inner chambers, rising pipe 2 is fixed in drinking-water pipe main body 4, copper sheet 5 is connected in rubber stopper 3 one ends by hinge, pulling handle 1 rises rubber stopper 3, and the air pressure of drinking-water pipe main body 4 energy is less than ambient pressure, and water enters drinking-water pipe main body 4 inner chambers, copper sheet 5 is upwards dug, and enters rising pipe 2 and flows out.
Preferably, described copper sheet 5 can only folk prescription to activity.
Preferably, described rising pipe 2 is installed on drinking-water pipe main body 4 upper ends.
Preferably, described drinking-water pipe main body 4 is shaped as square.
The utility model is easy to carry, and is simple and practical, saves resource, and the demonstration effect is more direct.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
