Problems solved by technology

However, these methods are relatively professional and complicated, and are not suitable as teaching aids for students to demonstrate
In addition, some existing contour models are only a single three-dimensional model, and it is difficult for students to convert between three-dimensional contour lines and two-dimensional plane contour lines
Although there are records in some literatures that convert three-dimensional contour lines and plane contour lines into each other, the general structure is complex, the operation is cumbersome, it is not easy to understand, and it is not easy to promote and use in teaching

Embodiment Construction

[0021] The contour line drawing model of this application includes a bracket 1, a simulated mountain peak 2 placed on the bracket 1, two ring-shaped slide rails 3 set up and down outside the simulated mountain peak 2, and one of the two ring-shaped slide rails. There is a mobile retractable drawing pen 4, and a transparent drawing paper 5 and a marker pen in addition. The mobile telescopic drawing pen 4 is composed of a telescopic pen 10 and a roller 9. The telescopic pen 10 is inserted in the middle of the roller 9, and the nib faces the simulated mountain peak. The upper part and the lower part are provided with card slots 11, and two circular slide rails are locked in the card slots 11. The bracket 1 includes a base 6 and a caliper 7 with a scale on one side provided on the base 6 , and a plurality of grooves 8 are provided on the caliper 7 in the longitudinal direction toward the side of the circular slide rail. The circular slide rail 3 can be stuck in different grooves,...

Abstract

The invention discloses a contour line drawing model which is used for drawing a three-dimensional contour line and a planar contour line. The contour line drawing model comprises a bracket, a simulated mountain peak, circular sliding rails and a mobile telescopic drawing pen arranged between the circular sliding rails, and is further provided with a piece of transparent drawing paper and a marking pen, wherein the bracket comprises a base and a caliper which is arranged on the base and is provided with scales on one side; and multiple grooves are longitudinally formed in one side, which faces the circular sliding rails, of the caliper. The contour line drawing model is simple in structure, easy to operate and high in practicability; and drawing of the three-dimensional contour line and drawing of the planar contour line can be completed together, and the understanding of a student for a contour line can be enhanced.

Description

technical field [0001] The invention belongs to teaching aids, in particular to a contour line drawing model. Background technique [0002] One of the tasks of middle school geography teaching is to help students establish geospatial thinking, and the study of contour lines is very helpful to the cultivation of students' spatial thinking. However, the contour line is difficult to understand, and teachers often spend a lot of effort in explaining it, but with little effect, which not only affects the enthusiasm of students in learning, but also reduces the work efficiency and teaching quality of teachers to a certain extent. [0003] Most of the current contour line drawing adopts the following method. First, determine the feature points of the landform, connect the points with the same height into a line according to the nature of the contour line, and then complete the drawing according to the actual situation; or use special software to draw the contour line. However, the...
