Abstract

The utility model discloses a stereo figure teaching model. A main body of the stereo figure teaching model is a transparent material and a cavity whose shape is the same with the shape of the model main body is processed in the main body. A sidewall of the model main body is provided with a water inlet pipe which is connected with the cavity so that one end of the water inlet pipe is arranged on a surface of the sidewall and the other end is inserted into the cavity. A rubber plug is arranged at a position of the water inlet pipe. An inner wall of the water inlet pipe is provided with an annular embossment used to assist seal. The rubber plug is provided with a seal ring groove used to be cooperated with the annular embossment. By using the above technical scheme, through injecting a colored liquid into the model main body and according to different taking positions of people, a cross section shape of the stereo figure is displayed so as to increase a visual stereoscopic effect during usage of the model.

Description

A kind of solid figure teaching mode

Technical field

The utility model relates to a kind of solid figure teaching mode.

Background technology

In the mathematical education of middle and primary schools, the cross-section structure of solid figure is teacher's a difficult problem often, because the three-dimensional sense organ of Most students is not very strong, the cross-section structure in a solid figure is difficult to explanation, and because resource-constrained, the teacher can not allow each the cutting of teaching stage property the classmate observe, so the explanation of most of profile graphics all is the shape that teacher draws profile graphics at blackboard, and because the impression of solid figure and planar graph is different, so the student is difficult to understand.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of solid figure teaching mode.

For reaching above purpose, be achieved through the following technical solutions:

A kind of solid figure teaching mode, solid figure teaching mode main body is transparent material, and the inner processing cavity identical with above-mentioned model body shape; The model main body wall is provided with the oral siphon that is communicated with cavity, and namely oral siphon one end is in sidewall surfaces, and the other end stretches into cavity inside; The oral siphon place is provided with rubber plug; The oral siphon inwall is provided with the annular projection for auxiliary seal; Rubber plug is provided with the closure gasket groove that cooperates for above-mentioned annular projection;

The utility model that has adopted technique scheme is by injecting colored liquid in the model main body, according to the difference of people's the position of taking, show the cross sectional shape of solid figure, the stereoscopic sensation directly perceived when using to strengthen model.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.

Description of drawings

Fig. 1 is perspective view of the present utility model.

Embodiment

A kind of solid figure teaching mode as shown in Figure 1, solid figure teaching mode main body 1 is transparent material, and the inner processing cavity identical with above-mentioned model main body 1 shape; Model main body 1 sidewall is provided with the oral siphon 2 that is communicated with cavity, and namely oral siphon 2 one ends are in sidewall surfaces, and the other end stretches into cavity inside; Oral siphon 2 places are provided with rubber plug 3; Oral siphon 2 inwalls are provided with the annular projection 4 for auxiliary seal; Rubber plug 3 is provided with the closure gasket groove 5 that cooperates for above-mentioned annular projection 4;

Adopted the utility model of technique scheme at first in model main body 1, to inject colored liquid by oral siphon 2, then by rubber plug 3 sealings (by annular projection 4 and closure gasket groove 5 fitted seal), the difference of working as people's the position of taking like this, the cross sectional shape that shows solid figure, the stereoscopic sensation directly perceived when using to strengthen model.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, appeal the equivalent embodiment that the technology contents that discloses is made a little change or is modified to equivalent variations when utilizing, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
