Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example (b): as shown in fig. 1, base 8, the support portion for a modular teaching board, projection board 1, first writing board 10 and second writing board 11 are installed to its top, carry out different shows to the teaching respectively, can let the mr contrast teaching to it is more clear, base 8 sets up to the triangle-shaped, sets up first piston rod 6 and first cylinder body 5, reciprocates in first cylinder body 5 through first motor 7 guide first piston rod 6 and adjusts the height of this teaching board with this.

Specifically, as shown in fig. 2, set up first clipboard 10, second clipboard 11, projection board 1 and pivot 3, when teaching the show, utilize handle 2 to articulate projection board 1 through pivot 3 from first clipboard 10 surface upset and open, it opens from the back upset of first clipboard 10 to articulate second clipboard 11 through pivot 3 again, sufficient teaching area and different regions are so as to reach better teaching purpose, overlap the front and back face of first clipboard 10 with projection board 1 and second clipboard 11 through pivot 3 is articulated in proper order after the use, reduce the area, so that remove and accomodate, reduce the space area of storage.

Specifically, as shown in fig. 3, set up second piston rod 13 and second cylinder 14, start second motor 15 through external control ware, back second motor guide second piston rod 13 inside second cylinder 14 is flexible from top to bottom, again drive connecting plate 12 and gyro wheel 9 by second piston rod 13 and reciprocate jointly in base 8, make teaching board move down gyro wheel 9 through second piston rod 13 and contact to the bottom surface when needs remove, can move to suitable place through gyro wheel 9, rethread second piston rod 13 is in the base 8 is withdrawed with connecting plate 12 and gyro wheel 9 upward movement, make base 8 fall to the ground and carry out the stable support to the teaching board, and base 8 sets up to the triangle-shaped support stability that has more to the teaching board.

Specifically, as shown in fig. 4, the roller 9 is retracted, the non-slip mat 16 is in contact with the ground when the base 8 falls to the ground, the non-slip mat 16 is made of rubber, the base 8 supports the non-slip mat while friction force is increased, and the teaching board is prevented from sliding to affect use.

The working principle is as follows: the teaching board starts a second motor 15 through an external controller when needing to move, a second piston rod 13 inside a second cylinder 14 is guided by a rear second motor to stretch up and down, then the second piston rod 13 drives a connecting plate 12 and a roller 9 to move up and down together in a base 8, the roller 9 is moved downwards through the second piston rod 13 to be contacted with the bottom surface, the teaching board can be moved to a proper place through the roller 9, the connecting plate 12 and the roller 9 are moved upwards through the second piston rod 13 to be retracted into the base 8, a base 8 is made to fall on the ground, an anti-slip pad 16 is contacted with the ground to stably support the teaching board, then the projection board 1 is hinged through a rotating shaft 3 to be turned over from the surface of a first writing board 10 by utilizing a handle 2, then the second writing board 11 is hinged through the rotating shaft 3 to be turned over from the back of the first writing board 10, teaching use can be carried out, sufficient teaching area and different areas can be used for achieving better teaching purpose, and the front and back surfaces of the first writing board 10 can be sequentially overlapped through the rotating shaft 3 to be retracted after use.
