Abstract

The invention discloses a management system based on cloud teaching. The management system comprises a teacher mobile terminal, a student terminal, a computer, a projector, a cloud server and a client terminal, wherein the projector is arranged on a fixing frame; the fixing frame is used for mounting the projector; the fixing frame comprises a vertical column, a first sleeve cylinder is arranged on the outer wall of the vertical column, and a first gear and a second gear are respectively arranged on the outer wall of the vertical column and the inner wall of the first sleeve cylinder in a matching way; two fixing plates are symmetrically arranged on the outer wall of the first sleeve cylinder, and a fixing shaft is arranged between the two fixing plates, and is vertical to the first sleeve cylinder; a second sleeve cylinder is arranged on the outer wall of the fixing shaft; a third gear and a fourth gear are arranged on the outer wall of the fixing shaft and the inner wall of the second sleeve cylinder in a matching way; a connecting rod is arranged on the outer wall of the second sleeve cylinder, and a fixing mechanism is arranged at the non-connecting end of the connecting rod. The management system has the advantage that the problem of failure to adjust the projection angle of the existing projector is solved.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a management system based on cloud teaching. Background technique [0002] With the advancement of science and technology, teaching is no longer the traditional book and blackboard teaching, and the application of multimedia teaching has emerged to improve the quality of teaching. [0003] A projector is an indispensable device in multimedia teaching. [0004] Projectors are also known as projectors. At present, projection technology is changing with each passing day. With the development of science and technology, the projection industry has also developed into a field with the highest micro-projection technology. [0005] The projector is a precision electronic product, which integrates machinery, liquid crystal or DMD, and electronic circuits, so it must be carefully protected during use, especially to prevent it from being impacted. [0006] The projector needs...
