Turn axis connection support bar, the supporting table top are uniformly provided with row's neck, and the support bar bottom is corresponding with neck nested
Connection, the blackboard inner chamber are provided with perforation, and the perforation both sides hold area provided with add-in card, and the add-in card holds area inner chamber and set
There is add-in card, the add-in card side is provided with mobile bar, and described mobile bar one end top and bottom is connected by spring seat
Fixture block, limiting plate is provided with the perforated base, and the perforated top is equipped with multiple hole clippings with bottom.
Furthermore, the fixture block is triangular prism structure, the fixture block and corresponding hole clipping nested encryptions.
Furthermore, the length scale of the add-in card and the length scale of mobile bar are identical, and are blackboard length
The a quarter of size.
Furthermore, the add-in card side is provided with handle, and handle outer wall is provided with slip-resistant texture.
Furthermore, described add-in card one end top and bottom is provided with limited post.
The utility model beneficial effect：A kind of adjustable type blackboard involved by the utility model, simple in construction, design is closed
Reason, by increasing add-in card on original blackboard, extends teaching area, key content can be carried out when necessary detailed
Introduce, add-in card can be stored in blackboard inner chamber when not in use, effectively raise the utilization rate in space, pass through fixture block
With the cooperation of hole clipping, add-in card can be made to be fixed in mobile certain position, writing on the blackboard will not shake when writing, fixture block
Using triangular prism structure, making it, direct pull add-in card is the disengaging and fixation of achievable fixture block and hole clipping, is passed through without pressing
Rotating disk is set, blackboard can be rotated, when student is more, is easy to station by way of rotation in the student of different azimuth
It can see, by support bar and corresponding neck nested encryptions, the angle of blackboard can be adjusted, it is practical.
