Abstract
The utility model discloses a visual demonstration model for spatial graphic relation analysis. The visual demonstration model comprises a base plate, a vertical column and a slanting pole with a scale ruler, wherein a first end of the vertical column is connected with the base plate; a second end of the vertical column is movably connected with the slanting pole; the slanting pole is a telescopic pole; and a laser is installed at the end part of the slanting pole. According to the visual demonstration model for spatial graphic relation analysis, by arranging the vertical column between the base plate and the slanting pole, a plane is showed through the base plate, and a straight line is showed through the slanting pole, so that students are helped to visually understand the relationship between the plane and the straight line; and in addition, as the laser is installed at the end part of the slanting pole, a downrange shape can be simulated.
Description
Technical field
The utility model belongs to the mathematical education field, particularly relates to a kind of displaying model directly perceived of space diagram relationship analysis.
Background technology
How much is important subjects, and just the student of introduction needs a understanding intuitively to the study of straight line, plane and straight line peace relation of plane.
Existing instruments used for education also do not have this educational aid, and the student can only rest on books, also have not deep problem on understanding.
The utility model content
The technical matters that (one) will solve
The technical problems to be solved in the utility model is: in order to allow the student have the instrument of deep study straight line, plane and a straight line and the relation between the plane.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of displaying model directly perceived of space diagram relationship analysis.
Wherein, the displaying model directly perceived of described space diagram relationship analysis comprises base plate, column and with the brace of rule, the first end of described column is connected with base plate, and the second end and brace are flexibly connected, described brace is expansion link, and the end of described brace is equipped with laser instrument.
Preferably, described expansion link is formed by multistage connecting rod assembly.
Preferably, described expansion link comprises draw-in groove and the connecting rod that matches with draw-in groove, and described draw-in groove is connected with column, and described connecting rod is provided with rule.
Preferably, the second end of described column is connected by hinge with brace.
(3) beneficial effect
Technique scheme has following advantage: the displaying model directly perceived of space diagram relationship analysis of the present utility model is by being provided with column between base plate and brace, be familiar with the plane by base plate, brace is familiar with straight line, thereby can help student's relation of understanding between the two directly perceived.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the structural representation of the second embodiment of the present utility model.
Wherein, 1: base plate; 2: column; 3: brace; 4: rotating shaft; 5: laser instrument.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
It is the structural representation of a kind of embodiment of the present utility model as Fig. 1, the displaying model directly perceived of this space diagram relationship analysis comprises base plate 1, column 2 and with the brace 3 of rule, the first end of described column 2 is connected with base plate 1, the second end and brace 3 are flexibly connected, described brace is expansion link, and the end of described brace is equipped with laser instrument 5.Structural apparatus of the present utility model is familiar with the plane by be provided with column between base plate and brace by base plate, and brace is familiar with straight line, thereby can help student's relation of understanding between the two directly perceived.And this brace is provided with rule, can measure the distance on column top, bottom surface, thereby can indirectly measure the angle of brace and bottom surface.In addition, in the end of brace, laser instrument is installed, can simulates the shape of directive.
Brace of the present utility model is expansion link, can realize that the length of brace is adjustable.Especially when the angle of observing between brace and bottom surface, can make contacting of brace and bottom surface by flexible brace.Preferably, described expansion link is formed by multistage connecting rod assembly, and every section connecting rod is connected by clip.The mode that is flexibly connected between column of the present utility model and brace can be hinged, be threaded, this embodiment's is to connect by rotating shaft 4.
In another kind of embodiment, this expansion link comprises draw-in groove and the connecting rod that matches with draw-in groove, and draw-in groove is connected with the second end of column, and connecting rod is flexible in draw-in groove, has realized equally the flexible of brace.This described connecting rod is provided with rule, is convenient to determine length.
For the ease of the motion of brace, preferably, the second end of described column is connected by hinge with brace.
Be the structural representation of the second embodiment of the present utility model as Fig. 2, the base plate of this embodiment is being provided with a plurality of concentric circles on the face of brace, thus the structure of being convenient to observe circular cone.
Also be provided with anti-slip veins on column of the present utility model, anti-skidding when having realized use.This column can be to be fixedly connected with the bottom surface, can be also to be flexibly connected, to realize the movement of column on the bottom surface.Preferably, this column and bottom surface threaded engagement.
Laser instrument also is installed on brace of the present utility model, by the state of opening to simulate ray of this laser instrument, is convenient to the definition that the student intuitively understands ray.Be provided with one and be used for controlling the laser works state of switch on brace.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
