Technical field
The utility model relates to a kind of Sliding blackboard with dust absorption blackboard eraser, refers to a kind of simple to operate especially, saves time and the Sliding blackboard with dust absorption blackboard eraser of energy-conserving and environment-protective.
Background technology
In current teaching, many needs of knowledge teachers are still had to write teaching study on blackboard, and need frequently wipe with blackboard eraser the knowledge content that teaching crosses, on blackboard, again again write the knowledge content of non-teaching, so, because teacher always needs to erase the board, and cause the state of mind of teacher to be interrupted, and traditional Method compare that erases the board is lost time, and when erasing the board, dust is comparatively large, have impact on the healthy of teachers and students.
Therefore, be necessary to design a kind of new blackboard equipment, to solve the problems of the technologies described above.
Utility model content
For Problems existing in background technology, the utility model object is to provide a kind of Sliding blackboard with dust absorption blackboard eraser, realizes simple to operate, saves time and energy-conserving and environment-protective.
The technical solution of the utility model is achieved in that a kind of Sliding blackboard with dust absorption blackboard eraser, comprise fixed frame, slide the front blackboard and rear blackboard be located on described fixed frame, front side bottom rear side bottom front blackboard and rear blackboard is connected to horizontal support bar, described horizontal support bar is provided with blackboard eraser, the rotary handle that described blackboard eraser is provided with dust catcher and brush and is connected with brush, described rotary handle controls brush and laterally or vertically rotates to select contact or do not contact front blackboard or rear blackboard, blackboard eraser on front blackboard is positioned at the front of rear blackboard, blackboard eraser on rear blackboard is positioned at the front of front blackboard.
In technique scheme, described blackboard eraser is provided with multiple air suction opening and is communicated with dust catcher.
In technique scheme, described brush is sponge bristle.
In technique scheme, described sponge brush hair is movably installed on described blackboard eraser.
The utility model with dust absorption blackboard eraser Sliding blackboard compared with prior art, blackboard eraser is connected with respectively by the rear side bottom blackboard before sliding and the front side bottom rear blackboard, and the rotary handle that blackboard eraser is provided with dust catcher and brush and is connected with brush, realize needing to utilize rotary handle rotational head when wiping word, slide front blackboard and rear blackboard just can wipe font, and dust catcher siphons away dust simultaneously.Reach simple to operate, save time and the beneficial effect of energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is that the utility model faces structural representation with the Sliding blackboard of dust absorption blackboard eraser;
Fig. 2 is Fig. 1 side-looking structural representation;
Fig. 3 is the side-looking structural representation of blackboard eraser in Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
