Working principle: when the device is used, the device can be conveniently driven to move through the universal wheel 3, so that the situation that the existing teaching device is fixed at a certain room position is greatly avoided, and the device can be used in other proper places. Firstly, the fixed buckles between the teaching boxes 1 on two sides are opened, then the teaching boxes 1 and the bases 2 on two sides are respectively unfolded in a rotating mode towards two sides, and at the moment, a human model for teaching and a teaching board 13 in the teaching boxes 1 are displayed in front of a teaching person and a person for learning.
After the teaching box 1 is unfolded, the servo motor 14 is started to drive the first straight gear 15 to rotate, so that the left second straight gear 16 and the left transmission shaft 4 are driven to rotate, the right transmission shaft 4 and the right second straight gear 16 are driven to rotate through the cooperation of the belt pulley 18 and the belt 19, the third straight gear 17 and the rotating shaft 5 are driven to rotate through the second straight gear 16, so that the lifting plate 20 is driven to move downwards, the supporting seat 22 is driven to move downwards through the supporting rod 21 by the lifting plate 20, and finally the supporting seat 22 contacts the ground to support the ground; meanwhile, the rotation of the transmission shafts 4 at the two sides can drive the movable sleeve 6 in threaded connection to move upwards, so that the teaching box 1 can be driven to move upwards to a designated position.
Meanwhile, when the teaching box 1 integrally ascends, the first sliding block 27 on the vertical plate 28 can slide along the first sliding rail 26, meanwhile, the driven gear 25 can move upwards and rotate under the meshing action of the transmission teeth 29 on the vertical plate 28, so that the rotating rod 23 and the second bevel gear 24 can be driven to rotate, the second bevel gear 24 can drive the linkage shaft 7 through the first bevel gear 8, the linkage shaft 7 rotates to drive the nut blocks 9 on the upper side and the lower side to move close to each other, the nut blocks 9 are mutually close to each other, the connecting rod 10 drives the mounting plate 11 to move towards the direction away from the inside of the teaching box 1, namely, the mounting plates 11 on the two sides can respectively drive the teaching manikin and the teaching plate 13 to move towards the outside of the teaching box 1, and then the nut blocks 9 are protruded outside the teaching box 1.
When a teaching person writes with the teaching board 13, when writing on the front, the spacing support rod 35 is rotated to be perpendicular to the transfer rod 34, then the spacing support rod 35 can be carried along the transverse shaft 32 through the sleeve 33, the fixing component of the spacing support rod 35 is inserted into the fixing hole 43, the fixing board 36 can be pressed to rotate to compress the return spring 37 in the fixing hole 43, after the fixing board 36 passes through the fixing hole 43, the fixing board 36 can be restored to the original position through the acting force of the return spring 37, and therefore the teaching board 13 can be fixed through the spacing support rod 35 and the fixing component.
When the front writing is finished, the fixing plates 36 on the two sides are pressed firstly, the return springs 37 are compressed, when the fixing plates 36 are pressed into the fixing holes 43, the limiting support rods 35 are moved and pulled out, the teaching plate 13 is not limited any more, then the teaching plate 13 is rotated upwards by one hundred eighty degrees along the connecting shaft 39, the reverse surface of the teaching plate 13 faces outwards, then the connecting sleeve 33 drives the switching rod 34 and the limiting support rods 35 to rotate upwards by one hundred eighty degrees, and then the fixing assembly penetrates through the fixing holes 43 to fix the teaching plate 13 by the same method, so that the writing teaching on the reverse surface of the teaching plate can be continued.
When writing teaching through the teaching board 13, can also drive the horizontal axis 32 and the teaching board 13 through both sides removal sliding seat 31 and reciprocate the position along guide rail 30, then fix sliding seat 31 through the fastening bolt on the sliding seat 31 again, and then can fix the teaching board 13, adjust the upper and lower position of teaching board 13.
