Description
Technical field
The utility model relates to a kind of science popularization device, particularly relates to the science popularization device of a simulation ellipsograph.
Background technology
Ellipsograph is that people use instruments used for education for a long time and drawing instrument, is one of very important teaching aid in mathematical education, but in significant period of time, draw ellipse be a very scabrous problem.Nowadays oval drawing tool mainly contains two kinds, and one is by compasses main body, draw point, and cord forms; Another kind forms by by the base plate of cruciform slideway and Track Point.We convert a kind of form makes children touch this important drawing instrument in mathematics, with the science popularization device of entertaining knowledge, allows children understand this knowledge point in advance, for later study is laid a solid foundation.
Utility model content
For achieving the above object, the utility model provides a kind of science popularization device of simulating ellipsograph, has cost low, and operation requirements is simple, security advantages of higher.
Simulate a science popularization device for ellipsograph, comprising: slider I, slide block II, Track Point, track pad, fixed head, handle and two axial screws; Described slider I and slide block II, comprise respectively: base plate, support column and tongue, and one end of support column has screw, and the other end is connected with base plate, and tongue is placed on base plate; Track pad and fixed head are provided with orthogonal traverse rod road and perpendicular track, the tongue of slider I and slide block II is placed in traverse rod road on track pad and perpendicular track respectively, base plate is placed in the middle of track pad and fixed head, and described track pad is connected with fixed head fastener; Track Point is provided with two preformed holes, and Track Point is fixed on the support column of slider I and slide block II through corresponding preformed hole by two axial screws, and handle is arranged on one end of Track Point; Described slider I and the tongue size of slide block II, high low dimensional are different, and the traverse rod road on track pad and the tongue size of perpendicular track and slider I and slide block II, high low dimensional match;
Described fixed head and track pad material are POM;
Described slide block material is white steel.
The beneficial effects of the utility model are: structure is simple, easy to operate, cost is low, security is high and the advantage such as sliding stability, and the crowd being applicable to multiple-age bracket understands the structure of ellipsograph;
Fixed head and track pad material are POM, have good stability, rub resistance and physical strength advantages of higher; Slide block material is white steel, can the advantages such as antirust and wearing quality is fabulous.
Accompanying drawing explanation
The utility model has accompanying drawing 5 width:
Fig. 1 is slide block structure schematic diagram;
Fig. 2 is the structural representation of track pad;
