Angle adjusting mechanism for demonstration of teaching projector and application method thereof

Abstract

The invention discloses an angle adjusting mechanism for demonstration of a teaching projector and an application method thereof. The angle adjusting mechanism comprises a rotating box. A rotating column is rotatably connected to the bottom of an inner cavity of the rotating box, a worm wheel is fixedly connected to the surface of the rotating column, a first rotating rod is rotatably connected tothe left side of the inner cavity of the rotating box, a worm is fixedly connected to the surface of the first rotating rod, and the top of the worm wheel penetrates the rotating box. By rotating a second rotating block, the rotating angle of the rotating box can be adjusted by the mechanism. By rotating a turnplate, the height of the rotating box can be adjusted by the mechanism. By rotating a first rotating block, the horizontal displacement of the rotating box can be adjusted by the mechanism. By rotating a threaded pipe, the inclination angle of the rotating box can be adjusted, so that the adjusting range of the rotating box is further increased, it can be ensured that an image exhibited by the projector can be aligned with curtain cloth, the teaching demonstrating effect is improvedand the comfort of students watching the curtain cloth is improved, and therefore, the teaching effect is further improved greatly.

Description

technical field [0001] The invention relates to the technical field of teaching projectors, in particular to an angle adjustment mechanism for demonstration of teaching projectors and a method for using the same. Background technique [0002] Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to learn and master cultural and scientific knowledge and skills purposefully, in a planned and organized manner, and promote the improvement of students' quality, so that they can become the people needed by society. The task of teaching is to impart systematic scientific knowledge to students, train students to form basic skills and skills, and develop students' intelligence and abilities. Cultivate students to have a firm and correct political direction, a world outlook of dialectical materialism and a communist moral character. To make students develop normally and grow up...

Problems solved by technology

[0004] The existing teaching projectors need to adjust the angle during use in order to achieve a better display effect. However, the angle adjustment mechanism for the traditional teaching projector demonstration cannot meet the needs of users during use, and the angle range adjustment is difficult. It is small, a
