Embodiment Construction
[0011] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] Depend on Figure 1 to Figure 5 It can be seen that the present invention includes a box body 1 with an upper end opening, and a cover plate 2 that can cover the opening of the box body 1 is hinged at the opening of the box body 1, the rear end of the cover plate 2 is hinged on the box body 1, and the front end is tilted. And there is a tendency to turn upwards around the hinge shaft. On the hinge shaft of the cover plate 2, a first reel 3 placed on the right side of the box body 1 is coaxially fixed, and a first reel 3 is wound and fixed on the first reel 3. The rope 4 is symmetrically provided with two uprights 5 at the front and back ends of the right side of the box body 1, and a connecting rod 6 is hinged on the inner side of each upright 5, and the connecting rod 6 on the rear side upright 5 is coaxially fix...

The invention relates to a remote teaching platform. According to the technical scheme, the platform comprises a box body, a cover plate is hinged to the opening of the box body; a first winding wheelis coaxially fixed on the cover plate hinge shaft; a first rope is wound and fixed on the first winding wheel; two stand columns are symmetrically arranged at the front and rear ends of the right side of the box, a connecting rod is hinged to the inner side of each stand column, a second winding wheel is coaxially and fixedly connected to the connecting rod positioned on the upright post on the rear side; the free end of the first rope is wound and fixed on the second winding wheel; a vertical pneumatic telescopic rod is arranged on the left side of the box body; a U-shaped bracket with an upward opening is fixed at the extending end of the pneumatic telescopic rod; a pneumatic cylinder with a piston capable of automatically resetting upwards is arranged in the box body, the pneumatic cylinder is communicated with the pneumatic telescopic rod through an air pipe, when the cover plate is pressed to the horizontal position, the connecting rod rotates to the vertical position from the horizontal position, meanwhile, the pneumatic cylinder is pressed, and the pneumatic telescopic rod is inflated to extend and drive the U-shaped support to move upwards along with the blackboard.
Description
technical field [0001] The invention relates to the field of educational equipment, in particular to a remote teaching platform. Background technique [0002] During the COVID-19 epidemic, teachers are required to teach students remotely, and with the development of the times, distance education has become the development trend of the times. At this stage, the main equipment for teachers to teach remotely is their own mobile phone or tablet. The camera is used for remote live broadcasting of lectures. When writing on the blackboard, the teacher needs to stand between the blackboard and the camera. Therefore, there needs to be a large distance between the blackboard and the camera to ensure that the teacher has enough space to write on the blackboard. However, the blackboard When the distance between the camera and the camera is too large, the students at the other end of the screen may not be able to see the content on the blackboard due to the limited pixels of the camera i...
