Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model relates to a teaching whiteboard convenient for English learning, which comprises a main body structure comprising a whiteboard body 1, a rear board sleeve 2 and a four-wire three-grid-line display device; the face of the whiteboard body 1 is a glass face, the four vertex angles of the whiteboard body 1 are provided with cutting sleeves 13, and the whiteboard body 1 is clamped on the rear board sleeve 2 through the cutting sleeves 13.

The main technical point lies in the four-wire three-grid-line display device, and I below detailed the setting of the four-wire three-grid-line display device as follows:

the three-grid-line four-wire display device comprises a box body 3 and three-grid-line display devices, wherein the box body 3 and the three-grid-line display devices are arranged on two sides of a white board body 1, a circuit board is arranged inside the box body 3, a plurality of wiring sockets 4 are arranged on the inner side of the box body 3, and a plurality of power switches 5 are arranged outside the box body 3.
