Abstract
The utility model relates to a cylinder-cylinder intersection line teaching model for mechanical drawing, which belongs to the field of teaching for mechanical drawing. The teaching model disclosed by the utility model comprises a cylinder I, a cylinder II, a cylinder III and a cylinder VII, wherein the radius of the cylinder I is less than the radius of the cylinder II; the radius of the cylinder III is equal to the radius of the cylinder II; the radius of the cylinder VII is greater than the radius of the cylinder II; and the cylinder I, the cylinder III and the cylinder VII vertically penetrate in the horizontally-placed cylinder II. The teaching model disclosed by the utility model is convenient to carry, simple and intuitive, and conducive to teaching middle school students to understand and grasp the conception of the intersection line.
Description
Technical field
The utility model relates to a kind of mechanical drawing post-post intersection teaching mode, belongs to the mechanical drawing teaching field.
Background technology
At present, in the mechanical drawing teaching, used model all is single model during the column intersection line explanation, and such model teacher carries very inconvenient when imparting knowledge to students at school, also can only watch one by one during the student viewing model, does not have certain contrast.
Summary of the invention
The purpose of this utility model provides a kind of mechanical drawing simple in structure post-post intersection teaching mode, makes teacher carry inconvenience to solve existing teaching mode, and student viewing does not have the problem of contrast.
The utility model is realized by following technical scheme: a kind of mechanical drawing post-post intersection teaching mode comprises right cylinder I 1, right cylinder II 2, right cylinder III 3, right cylinder VII 4; Right cylinder I 1 radius is less than right cylinder II 2 radiuses, right cylinder III 3 radiuses equal right cylinder II 2 radiuses, right cylinder VII 4 radiuses are greater than right cylinder II 2 radiuses, and right cylinder I 1, right cylinder III 3, right cylinder VII 4 are vertically just being passed through in the right cylinder II 2 of horizontal positioned respectively.
During use, with right cylinder II 2 horizontal positioned, can clear expression post in the front view-column radius changes and the Changing Pattern of intersection, simultaneously, by rear view, the hole-hole that also can give expression to different radii is passed through and the Changing Pattern of intersection mutually.
The beneficial effect that the utlity model has is: easy to carry, the simple, intuitive of teaching mode, and understanding and the grasp of middle school student to the intersection concept that help to impart knowledge to students.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Each label is among the figure: 1: right cylinder I, 2: right cylinder II, 3: right cylinder III, 4: the right cylinder VII.
