Problems solved by technology
[0003] However, there are big problems in the use of the existing interactive wall panoramic projection equipment. The existing interactive wall panoramic projection equipment depends on the installation and fixation on the top of the wall, which will cause damage to the top of the wall by punching holes, reducing the Convenience of use. The existing interactive wall panoramic projection equipment cannot adjust the position. When not in use, it cannot be automatically retracted, and it will always occupy space. The existing interactive wall panoramic projection equipment cannot adjust the angle, so it cannot be better. The corrected projection reduces the quality of the projection, thus affecting the teaching effect

The invention relates to the technical field of teaching aids, in particular to interactive wall panoramic projection equipment for teaching. The projection equipment comprises a bottom plate, a supporting plate and a hydraulic cylinder. The projection equipment is supported by using a supporting rod, so that the projection equipment does not need to be mounted and fixed by depending on a wall top, damage to the wall top by punching is avoided, and use convenience is improved. Through drive of a motor, a first rotating shaft rotates on a first lug plate, the first rotating shaft drives a ram,the ram drives a pull rod, the pull rod drives the projection equipment, and therefore rotation of the projection equipment is achieved. The interactive wall panoramic projection equipment for teaching is installed on a corner, through rotation the interactive wall panoramic projection equipment for teaching can be automatically unfolded, use and position adjustment are convenient, and the projection equipment can be automatically retracted through rotation when not in use, so that the occupied space is reduced.
Description
technical field [0001] The invention relates to the technical field of teaching appliances, in particular to an interactive wall panoramic projection device for teaching. Background technique [0002] With the continuous development of modern teaching technology, the introduction of multimedia into the classroom has greatly enriched the classroom teaching environment, from large-screen multimedia projection to interactive wall panoramic projection, which has effectively improved classroom teaching efficiency and expanded the amount of information for students. By using interactive wall panoramic projection equipment as a new teaching method, it is not only more conducive to stimulating students' interest in learning, but also reduces the difficulty of learning for students. It has many advantages that are very suitable for application in classroom teaching in schools. [0003] However, there are big problems in the use of the existing interactive wall panoramic projection eq...
