Description
(1) technical field under
The present invention relates to the blackboard in the realia, particularly a kind of lamination blackboard.
(2) background technology
At present, in teaching, teacher says that holding chalk class hour writes on blackboard, and blackboard is write will in time wipe behind the full word again and write, relatively lose time, and also relatively harder.
(3) summary of the invention
The present invention provides a kind of lamination blackboard that can be used alternatingly in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
Lamination blackboard of the present invention comprises blackboard surface, is enclosed in blackboard surface framework all around, and its special character is: described blackboard surface is two that press close to mutually, is connected with at least two ropes or chain between two blackboard surfaces; Be fixed with on the framework for rope or chain and overlap superincumbent pulley or sprocket wheel, the left and right sides of framework has the slide rail that slides for two blackboard surfaces.
Lamination blackboard of the present invention, the bottom of every blackboard surface all has stay cord.
Lamination blackboard of the present invention, the back fixation of the blackboard surface of front have a sponge identical with the lateral dimension of blackboard surface, and sponge is close to the front surface of the blackboard surface of back.
The invention has the beneficial effects as follows, two blackboard surfaces can be used alternatingly, use second after using up first again, drag stay cord after using up second, it is inferior that first blackboard surface moved up and down, the sponge of first blackboard back can be wiped clean second, and second can be continued to use, can save the time that erases the board.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is a backsight structural representation of the present invention.
Among the figure, the blackboard surface of 1 front, the blackboard surface of 2 back, 3 chains, 4 sprocket wheels, 5 sponges, 6 stay cords, 7 frameworks, 8 slide rails.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Lamination blackboard of the present invention comprises blackboard surface, is enclosed in blackboard surface framework 7 all around, and described blackboard surface is two that press close to mutually, is connected with at least two ropes or chain 3 between two blackboard surfaces; Be fixed with on the framework for rope or chain 3 superincumbent pulley of overlap joint or sprocket wheels 4, the left and right sides of framework 7 has the slide rail 8 that two blackboard surfaces are slided.The bottom of every blackboard surface all has stay cord 6.The back fixation of the blackboard surface 1 of front has a sponge 5 identical with the lateral dimension of blackboard surface, and sponge 5 is close to the front surface of the blackboard surface 2 of back.
Two blackboard surfaces of the present invention can be used alternatingly, use up the blackboard surface 2 of using the back behind the blackboard surface 1 of front again, drag stay cord 6 after using up the blackboard surface 2 of back, the blackboard surface 1 of front is moved up and down once, the sponge 5 of blackboard surface 1 back of front can be wiped clean the blackboard surface 2 of back, the blackboard surface 2 of back can continue to use, and can save the time that erases the board.
