SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a little blackboard of portable multiaspect show teaching, it can not only be carried through portable mode, but also can plug-type transport, has greatly made things convenient for and has carried, possesses the four sides moreover and writes, saves teacher and repetitious cleaning blackboard many times, saves teacher more time and physical power.
In order to achieve the above purpose, the utility model adopts the following technical scheme: it comprises mainboard 1, folded sheet 2, universal wheel 3, butterfly hinge 4, folding rod 5, roller bearing 6, portable ring 7, both sides are connected with folded sheet 2 about mainboard 1, and folded sheet 2 is equipped with butterfly hinge 4 with the 1 junction of mainboard, are equipped with the big curved hinge 21 of a plurality of in the middle of the folded sheet 2, portable ring 7 below is connected with roller bearing 6, and the both sides of roller bearing 6 are equipped with folding rod 5, and the big curved hinge 21 is connected to the other end of folded rod 5, and the bottom of mainboard 1 is equipped with a plurality of universal wheel 3.
And a connecting rod 8 is arranged between the rolling shafts 6. The connecting rod 8 is used for connecting the rollers 6 and simultaneously enabling the rollers 6 to synchronously move in the same direction.
The utility model discloses a theory of operation: the small teaching blackboard with multiple display surfaces is moved to a required room through the universal wheels 3, then the hand ring 7 is pressed downwards, the folding rod 5 is unfolded to a horizontal line through the roller 6, the connecting rod 8 drives the roller 6 below to unfold the folding rod 5, the pushing force for unfolding the folding rod 5 pushes the large bending hinge 21, the large bending hinge 21 pushes the folding plate 2 to unfold outwards, the butterfly hinge 4 is used for driving the main board 1 to move outwards when the folding plate 2 is unfolded, when the folding plate 2 is tiled, the main board 1 is pushed to the outermost side, the small teaching blackboard is unfolded in a rectangular shape to obtain the small blackboard with four surfaces, when the small blackboard is not used, the hand ring 7 is lifted, the roller 6 is moved upwards to drive the folding rod 5, the folding rod 5 pulls the large bending hinge 21, the large bending hinge 21 pulls the folding plate 2 to fold, the folding plate 2 drives the main board 1 to move through the butterfly hinge 4 when the folding plate 2 is folded, causing the main board 1 to move inwardly.
After the technical scheme is adopted, the utility model discloses beneficial effect does: it can not only carry through portable mode, but also can plug-type transport, has greatly made things convenient for and has carried, possesses the four sides moreover and writes, saves the teacher and repeatedly cleans the blackboard many times, saves more time of teacher and physical power.
