The above purpose is realized by the following technical scheme:

an interactive teaching device based on AR, the composition of which includes: a back plate, a top plate and an AR large screen, wherein the back plate is fixed on a vertical wall surface through a group of bolt assemblies, the back plate is vertically connected with the top plate, one side of the back plate is fixedly connected with two backing plates, each backing plate is vertically connected with an ear plate, the ear plate is vertically connected with a limiting column and a tension spring column A, the tension spring column A is connected with one end of a tension spring, the other end of the tension spring is connected with a tension spring column B which is vertically connected with the rotating plate, the rotating plate and the tension spring column B are of an integral structure, the lug plate is rotationally connected with one end of the long rotating rod through a rotating pin shaft, the other end of the long rotating rod is rotatably connected with the rotating plate through a rotating pin shaft, the lug plate is rotatably connected with one end of the short rotating rod through a rotating pin shaft, and the other end of the short rotating rod is rotatably connected with the rotating plate through a rotating pin shaft.

Interactive teaching device based on AR, rotor plate plane department be connected with big screen mounting panel, big screen mounting panel and AR big screen be parallel structure and be connected.

The back plate and the top plate have the same length and are of rectangular structures.

The interactive teaching device based on AR, long bull stick be L shape structure.

The utility model discloses the beneficial effect who reaches is:

1. the utility model fixes the back plate on the vertical wall surface, one side of the back plate is vertically connected with two ear plates, a motor is connected and installed between the two ear plates, the motor is fixed on the back plate, the output shaft of the motor is connected with the rotating pin shaft of the short rotating rod on one side, when the AR large screen needs to be folded, firstly, the motor is controlled by the personnel on the ground through the remote controller to rotate, the motor drives the rotating pin shaft on the short rotating rod to rotate, at the moment, the short rotating rod rotates along with the pointer, the short rotating rod can drive the rotating plate to rotate anticlockwise, when the rotating plate rotates, the rotating plate can drive the long rotating rod to rotate along with the pointer through the rotating pin shaft, because the large screen mounting plate on the rotating plate is connected with the AR large screen, therefore, the rotating plate can drive the AR large screen to rotate anticlockwise, when the AR large screen rotates to be parallel with the top plate, the folding work of the AR large screen is completed at the moment, when the AR large screen is unfolded, the motor reversal operation this moment, long bull stick and short bull stick anticlockwise rotation, and the rotor plate drives the big screen clockwise rotation of AR, and when the spacing post contact on one side of short bull stick and the otic placode, be parallel structure between big screen of AR and the wall this moment, the expansion work of accomplishing the big screen of AR.

2. The utility model has the characteristics of simple structure, convenient operation etc, when the big screen of AR does not use, can pack up the big screen of AR, prevent that children from causing the damage to the big screen of AR when beating an alarm, when folding up the big screen of AR simultaneously, can avoid sunshine to penetrate directly on the big screen of AR to increase the life of the big screen of AR.
