Embodiment Construction
[0042] The present invention will be further described below in conjunction with the accompanying drawings.
[0043] like figure 1 , figure 2 As shown in the figure, an audio-visual writing board with automatic reset of left and right movement includes a frame body 1, a left fixed board, a left moving board 2, a right moving board 3 and a right moving board 4. In the writing state, the left fixed board 2, the left moving board 2 and the left moving board Plate 3, right moving plate and right moving plate 5 are on the same vertical plane; such as image 3 , Figure 4 As shown, in the electronic teaching state, the left moving plate 3 is located in the front of the left fixed plate 2 , and the right moving plate 4 is located in the front of the right fixed plate 5 .
[0044] Also includes an inner frame body 6 and a sliding support mechanism;
[0045] like Figure 5 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the sliding support mechanism includes a m...

The invention provides an electronic teaching writing board capable of moving left and right and resetting automatically. The electronic teaching writing board comprises a frame body, a left fixing plate, a left moving plate, a right moving plate and a right moving plate and further comprises an inner frame body and sliding supporting mechanisms. The inner frame body is arranged on the middle portion in the left and right direction in the frame body. Moving gaps are reserved between the top and the bottom and the inner top and the inner bottom of the frame body. The top and the bottom of the left moving plate and the top and the bottom of the right moving plate are fixedly connected with supporting connecting plates of the two sliding supporting mechanisms. The sliding supporting plates are in sliding fit with the moving gaps and guide gaps. Rolling wheels are in rolling fit with horizontal guide wheel grooves. In the writing state, a pressure spring enables a moving base to be locatedon the rear portion, and when the writing state is converted into the electronic teaching state, the pressure spring is moved forwards and pressed. When the writing state is converted into the electronic teaching state, the left moving plate and the right moving plate move forwards, and then move left and right. When the electronic teaching state is converted to the writing state, the left movingplate and the right moving plate only need to move left and right, and operation is convenient.
Description
technical field [0001] The invention relates to an audio-visual writing board. Background technique [0002] In the current prior art, an audio-visual writing board that moves left and right and automatically resets includes a frame body, a left fixed board, a left moving board, a right moving board, a right moving board and a moving mechanism. When in use, the right fixed board moves forward, and then The right movement plate moves forward and then to the right. The problem is: the structure is complex and the operation is inconvenient. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an audio-visual tablet that can be moved left and right and automatically reset, which has the characteristics of simple moving mechanism, convenient operation and automatic reset. [0004] The present invention is realized in this way: an audio-visual writing board with left and right movement and automatic reset, including a frame body, a left fixed bo...
