Abstract
The utility model discloses the semi-automatic blackboard of a kind of slidingtype, comprise roller, left blackboard, right blackboard, holddown groove, bearing and blackboard rub piece, described left blackboard is connected with roller respectively by bearing with the both sides up and down of right blackboard, described roller is fixed in holddown groove, and described holddown groove is for be arrangeding in parallel; The right and left at the described right blackboard back side is respectively equipped with blackboard rub piece.The semi-automatic blackboard of slidingtype of the present utility model, by the mode of slidingtype, modular process is transformed blackboard, and the student that the restriction solved due to position is in each position, classroom can not see the problem of writing on the blackboard content on blackboard well.By designing the letter written with chalk on erasing blackboard cleverly, thus the burden of teacher can be alleviated in addition.
Description
Technical field
The utility model belongs to blackboard field, particularly the semi-automatic blackboard of a kind of slidingtype.
Background technology
One of blackboard very important culture and education instrument being undoubtedly education environment, blackboard coordinates the use of chalk to greatly facilitate the carrying out of teaching.But along with the continuous progress of educational undertaking, various culture and education instrument have also been obtained continuous development.Under such conditions, traditional blackboard can not meet the needs in classroom all sidedly.Wherein, the content that blackboard is write can not make the student being in each position, classroom see this problem due to the restriction of position, and the chalk writing on blackboard needs manually to wipe, and wastes the time on the one hand, is also a muscular labor on the other hand.
Utility model content
The purpose of this utility model is to provide a kind of slidingtype semi-automatic blackboard, by the mode of slidingtype, modular process is transformed blackboard, and the student that the restriction solved due to position is in each position, classroom can not see the problem of writing on the blackboard content on blackboard well.By designing the letter written with chalk on erasing blackboard cleverly, thus the burden of teacher can be alleviated in addition.
The purpose of this utility model can be achieved through the following technical solutions:
The semi-automatic blackboard of a kind of slidingtype, comprise roller, left blackboard, right blackboard, holddown groove, bearing and blackboard rub piece, described left blackboard is connected with roller respectively by bearing with the both sides up and down of right blackboard, and described roller is fixed in holddown groove, and described holddown groove is for be arrangeding in parallel; The right and left at the described right blackboard back side is respectively equipped with blackboard rub piece.
Described blackboard rub piece is semicylinder formula, and the length of described blackboard rub piece is identical with right blackboard height.
Described blackboard rub piece inside is provided with semicolumn plastic body.
Described right blackboard and blackboard rub piece junction are provided with projection, and the angle of described blackboard rub piece and right blackboard junction is 30 °.
Described blackboard rub piece is detachable rub piece, is fixed on the right blackboard back side by draw-in groove.
compared with prior art, its beneficial effect is the utility model:
The utility model solves the problem due to position and angle, make the student of each position, classroom can not see writing on the blackboard content on blackboard well, simultaneously blackboard of the present utility model can also save the time and physical workload that teacher erases the board, blackboard of the present utility model can optionally be wiped the content of blackboard and not wipe simultaneously, compared to existing blackboard, practicality is stronger.
Accompanying drawing explanation
Fig. 1 is the structural representation of the semi-automatic blackboard of slidingtype of the present utility model.
Fig. 2 is the enlarged drawing of the roller of the semi-automatic blackboard of slidingtype of the present utility model.
Fig. 3 is the left side enlarged drawing of the blackboard rub piece of the semi-automatic blackboard of slidingtype of the present utility model.
In figure: 1 is roller, 2 is left blackboard, and 3 is right blackboard, and 4 is holddown groove, and 5 is bearing, and 6 is blackboard rub piece, and 7 is semicolumn plastic body.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment
As Figure 1-3, the semi-automatic blackboard of slidingtype comprises roller 1, left blackboard 2, right blackboard 3, holddown groove 4, bearing 5 and blackboard rub piece 6, described left blackboard 2 is connected with roller 1 respectively by bearing 5 with the both sides up and down of right blackboard 3, described roller 1 is fixed in holddown groove 4, and described holddown groove 4 is for be arrangeding in parallel; The right and left at described right blackboard 3 back side is respectively equipped with blackboard rub piece 6, and described blackboard rub piece 6 is semicylinder formula, and the length of described blackboard rub piece 6 is highly identical with right blackboard 3, and described blackboard rub piece 6 inside is provided with semicolumn plastic body 7.Described right blackboard 3 is provided with projection with blackboard rub piece 6 junction, and described blackboard rub piece 6 is 30 ° with the angle of right blackboard 3 junction.Described blackboard rub piece 6 is detachable rub piece, is fixed on right blackboard 3 back side by draw-in groove.
When pulling left and right blackboard, the letter written with chalk on left blackboard can the blackboard rub piece of right blackboard be wiped clean; When not needing the letter written with chalk wiped below, word can be write on left blackboard.
