Apparatus for demonstrating be designed to realize the visual in image of teaching, deepen student and understand, laid for the study of follow-up solid geometry
Solid foundation.
Utility model content
The purpose of this utility model is to provide a kind of different surface beeline angulation apparatus for demonstrating, passes through the antarafacial for the relation of shifting one's position
Straight line demonstrates the visual in image position relationship for showing different surface beeline, and passes through the angulation that parallel lines device obtains different surface beeline
Demonstration, deepen the understanding of the position relationship between different surface beeline.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of different surface beeline angulation apparatus for demonstrating, including surface plate, straight line cutting, different surface beeline rod, parallel lines device and insert
Hole, the straight line cutting and the jack are arranged on the surface plate, and the different surface beeline rod lower end connects vertical rod, described
Vertical rod is inserted in the jack, and can be rotated, and the parallel lines device is by transverse slat, plate, chute, cunning and parallel lines rod group
Into the transverse slat is vertical with the plate to be fixedly connected, and the slide plate is vertical with the parallel bar to be fixedly connected, the transverse slat
The chute is being set up perpendicular to the plate side, the plate is inserted into the straight line cutting, the slide plate
It is inserted into the chute.
Further, the quantity of the straight line cutting and the jack is respectively greater than 1.
Further, the quantity of the straight line cutting is more than or equal to 3, and the quantity of the jack is more than or equal to 3.
Further, the quantity of the straight line cutting is 3, and the quantity of the jack is 5.
Further, the angle between the different surface beeline rod and the vertical rod is between 90 ° ~ 180 °, preferably 120 ° ~
Between 150 °.
The beneficial effects of the utility model：
1. the utility model embodies the position relationship between different surface beeline visual in imagely, the vertical rod of different surface beeline rod can
To be rotated in jack, straight line cutting has a plurality of, and jack is multiple, realizes the diversity of different surface beeline position relationship.
2. parallel lines device is used for the parallel lines for making straight line cutting, the translation of straight line cutting is realized, image shows straight line quarter
The angular relationship of groove and different surface beeline rod.
