The elongated end for stating left top of the trellis of rectifying is fixedly connected, the bottom end of the fixing axle I with the left side be set rectify the elongated end of frame bottom
It is fixedly connected, the left end of the correct frame is fixed with turning set I, and the turning set I is socketed in outside the fixing axle I, and described
Turning set I is rotatablely connected by bearing and the fixing axle I；
It is inlaid with two pieces of blackboards respectively by two fixed frames I in the correct frame, is respectively arranged in the correct frame
Positive positive side blackboard I and the back side blackboard I that the correct frame back side is set, the positive side blackboard I and the back side blackboard I
Between be equipped with fixing axle II, the fixing axle II is arranged in the centre of the correct frame, and the both ends difference of the fixing axle II
It is fixedly connected with the lower long side of the upper long side of the correct frame and the correct frame, and the extending direction of the fixing axle II and institute
The extending direction for stating fixing axle I is parallel, is socketed with turning set II outside the fixing axle II, and the turning set II by bearing with
The fixing axle II is rotatablely connected, and is fixed with more fixed links I, and one end of the fixed link I and institute on the turning set II
The outer surface for stating turning set is fixedly connected, and the other end of the fixed link I is fixedly connected with the fixed frame I；
It is inlaid with two pieces of blackboards respectively by two fixed frames II in the left frame, is respectively arranged in the left frame
Positive positive side blackboard II and the back side blackboard II that the left frame back side is arranged in, the positive side blackboard II and the back side are black
It is equipped with fixing axle III between plate II, and the fixing axle III is arranged in the left side and rectifies the centre of frame, and the two of the fixing axle III
The upper long side of frame is rectified at end with the left side respectively and the left side is rectified, and the lower long side of frame is fixedly connected, the extending direction of the fixing axle III
It is parallel with the extending direction of the fixing axle I, it is socketed with turning set III outside the fixing axle III, and the turning set III passes through axis
It holds and is rotatablely connected with the fixing axle III, III is fixed with more fixed links II, and the one of the fixed link II on the turning set
End is fixedly connected with the outer surface of the turning set III, and the other end of the fixed link II is fixedly connected with the fixed frame II.
The positive side bottom end and back side bottom end of the left frame and the positive side bottom end of the correct frame and back side bottom end are equipped with
Fixation hole and fixed plug matched with the mounting hole.
Because in classroom the space at the place at dais be not it is especially big, blackboard overturning get up it is relatively difficult, so the present invention is set
The blackboard of the blackboard and right side of having set left side can be rotated around the fixing axle I, when teacher wants using the blackboard for being located at right side
Back side blackboard when, the correct frame pull-up is rotated around the fixing axle I, after turning an angle, pulls out the fixation
Fixed plug in hole, the blackboard for being located at right side is then rotated, even if the positive side blackboard on the right side is rotated to 180 °, make former back
Side blackboard is rotated to front, and fixed plug is finally got back into fixation hole again, and the blackboard for being located at right side is set back further
Write clean blackboard.The usable floor area for increasing blackboard facilitates teacher not have to often erase the board.
The present invention can be widely popularized in fields such as blackboards based on the above reasons.
