Abstract
The utility model relates to a high school mathematics teaching tool for demonstrating an elliptical orbit. The teaching tool is characterized in that the tool consists of a box body, a support platform, a glass plate, a sliding block, a connecting rod, a light-emitting diode, a first orbit rod, a rotating rod, a second orbit rod, a motor and a rotating rod support seat. According to the scheme, the provided teaching tool has the following beneficial effects: the structure is simple, novel and unique; the formation orbit of the ellipse can be demonstrated vividly; and thus students can understand and master the related knowledge of the plane analytic geometry conveniently.
Description
Technical field
The utility model relates to a kind of teaching aid technical field, relate in particular to a kind of for demonstrating the high school mathematics teaching aid of elliptical orbit.
Background technology
In high school mathematics teaching, plane analytic geometry relevant knowledge more complicated, the explanation of attending class in the situation that there is no teaching aid is got up more abstract, and student is also difficult to understand, and there is very large difficulty in this part knowledge of students therefore.
Utility model content
In order to overcome above-mentioned technical matters, it is a kind of for demonstrating the high school mathematics teaching aid of elliptical orbit that the utility model provides, and the technical scheme of employing is as follows.
For demonstrating a high school mathematics teaching aid for elliptical orbit, it is characterized in that, comprise casing, brace table, glass plate, slide block, connecting rod, light emitting diode, the first Track Point, dwang, the second Track Point, motor and dwang bearing; Described casing front side is without baffle plate; Described glass plate is arranged on the front side of described casing; On described brace table, offer a long rectangular opening and a chute, described brace table is arranged on the middle part in described casing; In the chute that brace table described in described slide block is embedded in is offered; Described dwang bearing is arranged on the rectangular opening rear side on described brace table; Described motor is arranged on described brace table, near dwang bearing place; Described dwang is arranged on described dwang bearing, is connected with the axle of described motor; Described connecting rod one end and described slide block are hinged, and the other end and described dwang are hinged; One end of the first described Track Point and described position place, connecting rod middle and upper part are hinged, and one end of the other end and described the second Track Point is hinged; Position, the middle and upper part place of the other end of the second described Track Point and described dwang is hinged; Described light emitting diode is embedded in the first described Track Point and the second described Track Point place that is hinged; The length of described connecting rod and described dwang equal in length; The first described Track Point length and the second described Track Point equal in length.
The beneficial effects of the utility model are: simple in structure, novel unique, the formation track of demonstration ellipse that can be vivid, is convenient to understanding and the grasp of student to plane analytic geometry relevant knowledge greatly.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1 to Figure 3, a kind of for demonstrating the high school mathematics teaching aid of elliptical orbit, it is characterized in that, comprise casing 1, brace table 2, glass plate 3, slide block 4, connecting rod 5, light emitting diode 6, the first Track Point 7, dwang 8, the second Track Point 9, motor 10 and dwang bearing 11; Described casing 1 front side is without baffle plate; Described glass plate 3 is arranged on the front side of described casing 1; On described brace table 2, offer a long rectangular opening and a chute, described brace table 2 is arranged on the middle part in described casing 1; In the chute that brace table 2 described in described slide block 4 is embedded in is offered; Described dwang bearing 11 is arranged on the rectangular opening rear side on described brace table 2; Described motor 10 is arranged on described brace table 2 near dwang bearing 11 places; Described dwang 8 is arranged on described dwang bearing 11, is connected with the axle of described motor 10; Described connecting rod 5 one end and described slide block 4 are hinged, and the other end and described dwang 8 are hinged; One end of the first described Track Point 7 and described connecting rod 5 position, middle and upper part places are hinged, and one end of the other end and described the second Track Point 9 is hinged; Position, the middle and upper part place of the other end of the second described Track Point 9 and described dwang 8 is hinged; Described light emitting diode 6 is embedded in the first described Track Point 7 and the second described Track Point 9 place that is hinged; The length of described connecting rod 5 and described dwang 8 equal in length; The first described Track Point length 7 is equal in length with the second described Track Point 9.
When teaching explanation, open motor 10, motor 10 drives dwang 8 to rotate, and slide block 4 moves back and forth along the chute on brace table 2, and light emitting diode 6 shows elliptical orbit; Thereby motivate students' interest in learning, deepen the understanding of student to relevant knowledge.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
