Scrubbing pad 27, tabletting 26 is arranged on the cell wall contact position of friction pad 27 and L-shaped groove, by setting combination fix bar 21, wall to paste bar 22
With spring lever 23 so that when wall patch bar 22 is fixed on the wall, by the active deformation of spring lever 23, change the main He of panel 1
The distance between wall.
If on smooth metope, teaching panel of the invention has another mounting mode, such as Fig. 6 institutes
Show, pasted in wall and be provided with center sucker 281 in the middle of the one side setting wall junction 28 that bar 22 is contacted with wall, wall junction 28, center is inhaled
Some outer ring suckers 282 are evenly arranged with around the outer ring of disk 281 when being arranged on slippery walls, the He of center sucker 281 can be passed through
The auxiliary suction-operated of outer ring sucker 282, mitigates the endurance that wall pastes bar 22, in the condition without wall hanging, can be hung by rear
29 hang on bar or rope, and to change the mode of wall hanging, the overall usability of increase panel passes through the embedded cunning of rear fix bar 21
Bar 24 is relative in the L-shaped groove that the main dorsal part of panel 1 is set to be slided, so as to change the relative ground distance of main panel 1, lifting is overall
Display height, by hidden screw 25 in screwdriver turn, improve the pressure between friction pad 27 and tabletting 26, rubbed so as to increase
Frictional force between scrubbing pad 27 and embedded draw runner 24 so that the overall lifting operations of panel are more stable.
The accommodating mechanism of the present invention is hidden in the bottom of main panel, and simple operation had both realized the storage work(of educational aid
Can, and the integrally-built uniformity of main panel is not destroyed；Panel of imparting knowledge to students is in the state of, by sealing block at the top of main panel
Groove in pull out after, sealing plate is pulled to bottom with wrapping up in tilt at the top of main panel, wrap up in tilt ink screen is carried out it is effective
Proofing dust and protecting；The present invention pastes bar by wall and fixed on the wall, and by the active deformation of spring lever, change main panel and wall it
Between distance, enhance the flexibility that uses of teaching panel；The setting of wall junction adds the stability of wall hanging simultaneously；And
When there is no the condition of wall hanging, it can be hung over by rear on bar or rope, to change the mode of wall hanging, the overall use of increase panel
Property, so as to improve the use scope of teaching panel, it is adaptable to a variety of work teaching environments.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
