Dimension marking demonstrating device

Abstract

The invention discloses a dimension marking demonstrating device, which comprises a casing, wherein a support plate is fixedly connected onto each of the left and right ends of the bottom of the casing through a support leg; a magnetic plate is embedded in the middle end of the bottom of each support pate; the bottom of each support plate is fixedly connected with a rubber plate; a center processing unit, an image collecting module, a marking judging module and a marking point picking module are sequentially and fixedly connected onto the left end of an inner cavity of the casing from top to bottom; a camera installing plate is fixedly connected onto the middle end of the top of the casing. Through the effects of a first sliding device, a second sliding device, a first electric telescopicrod, a first inclination angle sensor, a first radar distance measuring laser, a motor, a third sliding device, a second electric telescopic rod, a second inclination angle sensor and a second radar distance measuring laser, the marking requirements of people on the graph horizontal direction and vertical direction, the circular arc, the circular center, the diameter and the radius can be met; theteaching burden of teachers is reduced; meanwhile, the study interest of students is also improved.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a demonstrator for dimension marking. Background technique [0002] Teaching is a human-specific talent training activity composed of teachers' teaching and students' learning.

[0002] Teaching is a human-specific talent training activity composed of teachers' teaching and students' learning. Through this activity, teachers guide students to learn and master cultural and scientific knowledge and skills purposefully, in a planned and organized manner, and promote students' quality. Improve and make them become the people needed by the society. Teaching equipment is the general term for all kinds of equipment used to enable students to understand the teaching content intuitively and visually and the equipment used by teachers in teaching. It can improve students' learning interest and enrich their perceptual knowledge. , Help form clear concepts, develop students' observation ability and thinking ability, generally divided into three categories: ordinary teaching aids, special teaching aids, and children's teaching aids. In the existing teaching process, the teacher is manually operating when dimensioning the graphics. , which not only increases the teacher's teaching burden, but also reduces the students' interest in learning. Therefore, we propose a demonstrator for dimensioning
