Abstract
The utility model discloses a cylinder intersecting body cartographic model, which is formed by intersecting four cylindrical bodies whose diameters respectively are D1, D2, D3 and D4, and the diameters meet the relation: D1=D2>D3>D4; and the interior is formed by uniformly intersecting three horizontally-arranged hollow cylindrical bodies whose diameters respectively are D1, D2 and D3 and a U-shaped body with the height of d4 with a vertically-arranged hollow cylindrical body with the diameter d0, and the diameters meet the relation: d1>d2=d0>d2>d3>d4; the front and rear parts are mutually symmetrical and the left and right parts are mutually symmetrical, the front and rear parts are cut along a symmetry plane to form a front piece and a rear piece, and the front piece is connected with the rear piece by using elastic rubber buckles. The cylinder intersecting body cartographic model has the beneficial effects that: four cylinders with different diameters and positions are pairwise-intersected to form external intersecting lines; the model is provided with holes in the interior and the holes are pairwise-intersected to form internal intersecting lines, and the shapes of the internal intersecting lines can be observed through sectioning; and a variable intersecting line shape is formed by pairwise-intersecting cylindrical bodies with different outer diameters and hole diameters.
Description
Technical field
The utility model relates to a kind of teaching mode, and more specifically, it relates to a kind of cylinder intersecting body cartographic model.
Background technology
At present, column intersection line model generally can not be shown inside and outside intersection form simultaneously, or is not enough to show the various forms of right cylinder intersection comprehensively, the intersection of having relatively high expectations for spatial thought teaching, and demonstration effect is not enough.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, the cylinder intersecting body cartographic model that teaching efficiency is good.
This cylinder intersecting body cartographic model, is respectively D by four diameters
1, D
2, D
3, D
4right cylinder pass through and form mutually, diameter Relationship: D
1=D
2>D
3>D
4; Inside is d by horizontally disposed diameter

3>d
4; Front and back are symmetrical mutually with left and right, and front and back section along the plane of symmetry, form anter and rear panel, and described anter is connected with elastic caoutchouc button with rear panel.
The beneficial effects of the utility model are: the cylinder differing in four diameters and position intersects between two, forms outside intersection; Internal openings also intersects the inner intersection of formation between two, through dissecing, can observe inner intersection form; Through the right cylinder in various outer diameter or aperture between two, intersect and form a vicissitudinous intersection form of richness, form column intersection line integral type teaching mode.The utility model can show that the outside intersection of cylinder can show again its inner intersection, and discloses intersection variable condition, and demonstration project exquisiteness is integrated, one module multiple usages.
Accompanying drawing explanation
Fig. 1 is the utility model assembling structure figure;
Fig. 2 is that the A of Fig. 1 is to partial view;
Reference numeral: anter 1, rear panel 2, elastic caoutchouc button 3.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
Referring to shown in Fig. 1 to Fig. 2, the utility model outside is respectively D by four diameters
1, D
2, D
3, D
4right cylinder pass through and form mutually, diameter Relationship: D
1=D
2>D
3>D
4; Inside is d by horizontally disposed diameter
1, d
2, d
3three hollow cylinders and a d
4" U-shaped body " unified diameter with a vertical layout is d
0hollow cylinder pass through and form mutually, diameter Relationship: d
1>d
2=d
0>d
2>d
3>d
4; Front and back are symmetrical mutually with left and right, and front and back section along the plane of symmetry, form anter 1 and rear panel 2, with elastic caoutchouc button 3, are connected.
Elastic caoutchouc button 3 adopts rubber soft material to make, hollow, and profile is bud shape, and middle micro-drum can be done certain mismachining tolerance adjustment; Elastic caoutchouc button one end can be screwed with glue or middle perforate, just can be sealed and separated by suitable power.
In this teaching mode when combination, is shown the outside intersection form of cylinder, shows its inner intersection form, and observes the evolving trend of intersection when two body diameters change relatively, and can be used as cut-open view teaching cases and apply to drawing teaching when separated.
