Description
Technical field
The present invention relates to a kind of blackboard, more particularly, to a kind of semi-automatic erasing type spool blackboard.
Background technology
Blackboard is as one of indispensable apparatus in classroom, and the blackboard that can record class-teaching of teacher personal letter is always that we pay close attention to
Emphasis.Blackboard is applied to the hard objects such as plank, cement surface with blacking from earliest, to the water mill glass of the nineties
Glass, present color coated steel sheet, composite panel.Epoch also begin to the complicated various of change in progress, the species of blackboard.Multimedia is taught
The teaching aid commonly used in is mainly blackboard and projecting apparatus, and function is relatively simple, it is impossible to meet multimedia education well.
Blackboard needs artificial erasing out handwriting, can influenceed as the teaching aid of repeated writing, mostly chalk-writing after writing
The continuity of classroom instruction.Projecting apparatus is as the important tool of displaying teaching, and usually used is soft and coarse projection screen,
It can not be used for writing.During teaching is shown, if necessary to manual writing on the blackboard, projection screen can influence the use of blackboard, enter
And the efficiency of teaching in multimedia teaching classroom can be reduced.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect there is provided a kind of semi-automatic erasing type spool blackboard,
It is arranged on by flexible-belt on central siphon, so as to solve the above problems.
To achieve the above object, the present invention provides following technical scheme：A kind of semi-automatic erasing type spool blackboard, including the
One transmission shaft, central siphon, crank, the first support column, first base, plate body, flexible-belt, the second transmission shaft, ledge for chalk on blackboard, the second support
Post and second base, it is characterised in that central siphon is provided with first transmission shaft, the central siphon lower end is connected with crank, described
First support column lower end is connected with first base, and the plate body side is provided with the first transmission shaft, and the plate body is away from the first transmission
Axle one end is provided with the second transmission shaft.
As a preferred technical solution of the present invention, ledge for chalk on blackboard side lower end is provided with the first support column, described remote
The second support column is provided with from first support column one end, the second support column lower end is connected with second base.
As a preferred technical solution of the present invention, the flexible-belt is connected to the first transmission shaft and second by central siphon
Between transmission shaft, the plate body lower end is provided with ledge for chalk on blackboard.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of semi-automatic erasing type spool blackboard, is connected by central siphon lower end
Crank is connected to, shake crank that can be manual rotates central siphon, wipes the letter written with chalk on flexible-belt, it is simple in construction, easy to operate
Arrive when erasing chalk word erases the board especially for teacher and served very big help.
