Abstract

The invention belongs to the technical field of teaching devices, and particularly provides a multimedia teaching device. The following scheme is currently provided to solve the problems that the angle of a teaching device cannot be conveniently adjusted, so that people cannot see clear pictures sometimes, meanwhile, the teaching device cannot be stably supported in the display process, and therefore the stability of the device is poor. The multimedia teaching device comprises base. An equipment box is fixed to the outer wall of the top of the base through a screw, a fixing frame is arranged on the inner wall of the bottom of the equipment box, the inner wall of the fixing frame is connected with a two-way threaded rod through a bearing, and the outer wall of the two-way threaded rod is sleeved with two sliding rings. A supporting rod is adjusted into an inclined state by controlling an electric telescopic rod and piston rods to extend, thus, the supporting rod can be used as a handleto push the device to move, the angle of the device is conveniently adjusted, people can see the clear pictures, the device can be stably supported in the display process, and the stability of the device is good.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to multimedia teaching devices.
