Abstract

The invention discloses an English learning device with a projection device capable of realizing leftward and rightward projection, and relates to the technical field of projectors. By the adoption ofthe English learning device with the projection device capable of realizing leftward and rightward projection, the problems that an existing projector and an existing projector hanging bracket cannotmove or rotate and have many limitations in use are solved. The English learning device with the projection device capable of realizing leftward and rightward projection comprises an angle adjustmentdisk, wherein a rotary rod at the top of a device body mounting plate is rotatably connected into the angle adjustment disk. When the English learning device is fixed on a ceiling to be used, a projector body can rotate to realize leftward and rightward projection and can also move vertically and horizontally so that the projector body can be used in different environments to meet different requirements, the flexibility is high, the using and learning experience of teachers and students is improved, and the practicability of the English learning device is improved.

Description

technical field [0001] The invention belongs to the technical field of projectors, and more particularly, relates to an English learning device equipped with left and right projectable devices. Background technique [0002] In modern society, with the popularization of multimedia teaching instruments in colleges and universities, more teachers use projector interactive teaching to replace the process of blackboard writing teaching. A projector, also known as a projector, is a device that can project images or videos onto a screen, and is widely used in homes, offices, schools, and entertainment venues. [0003] With the continuous progress of science and technology, multimedia teaching has become a mainstream teaching method, and has been widely used in multimedia teaching and learning of English and various subjects. , projectors are often bolted to the ceiling using a ceiling mount. [0004] For example, in the patent with the application number: CN201110293679.4, it is ...
