Problems solved by technology

Because multimedia has the characteristics of graphics, text, sound and even moving images, it has many characteristics and functions that are especially valuable to the education and teaching process. These characteristics and functions are not available or not fully available in other media. Yes, projection equipment is an important part of multimedia equipment. Traditional projection equipment is a fixed device, which cannot adjust the projection angle at any time, and cannot adjust the distance from the projection equipment to the screen following the size of the screen.

Abstract

The invention discloses an adjustable projection device for an art training class. The device comprises an internal threaded pipe, an internal thread is arranged in the internal threaded pipe, a motor fixing disc is fixedly arranged at the top end of the internal threaded pipe, a top fixing disc is arranged above the motor fixing disc, fixing connecting rods are fixedly connected between the top fixing disc and the motor fixing disc, and a screw rod fixing lug is arranged at the position, close to the lower portion, of the internal threaded pipe. According to the adjustable projection device, a lifting screw rod rotates in the internal threaded pipe, so that the height of a projector is adjusted; a first screw rod rotates to drive a worm gear to rotate, so that the rotation angle of a lifting disc and the angle of the projector in the horizontal direction are adjusted; a second screw rod rotates to drive a semicircular worm gear to rotate, so that the angle of the projector in the vertical direction is adjusted; and a movable roller fixing lug rotates on a rail rod to drive the whole device to move, so that the distance between the projector and a curtain is adjusted, and the problems proposed in the background art are solved.

Description

technical field [0001] The invention relates to the technical field of educational equipment, in particular to an adjustable projection equipment for art training courses. Background technique [0002] The origin of art has always been called "the mystery of the Sphinx" by the academic circles, mainly because people know very little about the early history and artistic materials of human beings. Nevertheless, many scholars in history have made unremitting exploration and efforts in this field, and put forward various theories about the origin of art from different angles. These theories reveal certain conditions and basis for the occurrence of human art from different angles, and are of great value to art learning and art education. Although these theories on the origin of art inevitably involve all aspects of human art, the discussion on the origin of fine arts is usually an important aspect of these theories. Because multimedia has the characteristics of graphics, text, ...
