A platform for research: civil engineering, architecture and urbanism
The invention relates to the technical field of multimedia classrooms, in particular to an intelligent multimedia classroom for online education and a use method. The device comprises a classroom platform, a plurality of lifting grooves are formed in the top of the classroom platform, screw rods are rotationally arranged at the edges of the lifting grooves, and racks are arranged at the corners of the ends of inner cavities of the lifting grooves; a lifting plate is arranged on the outer wall, close to the bottom, of the ladder frame, and the surface of the lifting plate is in threaded fit connection with the outer wall of the lead screw; one end of the rotating rod rotatably extends out of the ladder frame and is connected with a gear disc, the outer wall of the gear disc is in meshed connection with the rack, the outer wall of the rotating rod is movably connected with a first hinge plate, the end of the first hinge plate is movably connected with a second hinge plate, and the end of the second hinge plate is movably connected with the bottom of the listening table. The sitting height can be adjusted according to the actual height of a person sitting down, it is ensured that the person can see a blackboard or a projector, and the capacity of a multimedia classroom is saved.
本发明涉及多媒体教室技术领域，具体地说，涉及一种在线教育用的智能化多媒体教室及使用方法。其包括教室地台，教室地台顶部开设有多个升降槽，升降槽边缘处转动设有丝杆，升降槽内腔端部拐角处设有齿条；升降槽内部滑动设有阶梯架，阶梯架靠近底部的外壁设有升降板，升降板表面与丝杆外壁螺纹配合连接；升降槽内腔底部转动设有转杆，转杆一端转动伸出阶梯架内部，且连接有齿轮盘，齿轮盘外壁与齿条啮合连接，转杆外壁活动连接有第一铰接板，第一铰接板端部活动连接有第二铰接板，第二铰接板端部活动连接听讲桌底部。本发明可以根据实际坐下人员的身高调节坐立高度，确保可以看到黑板或投影仪，且节省多媒体教室的容量。
