Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
A kind of blackboard of the present invention, as Figure 1-Figure 4, the outside framework 1 comprising base 2 and be arranged on base 2, be mounted alternately with totally three end to end lower single track chutes 6 and lower double track chute 8 along floor length direction inside the base plate of outside framework 1, wherein both sides are lower single track chute 6, and centre is lower double track chute 8.Alternately install totally three end to end upper single track chutes 7 and upper double track chute 9 along top board length direction inside the top board of outside framework 1, wherein both sides are upper single track chute 7, and centre is upper double track chute 9.Each upper single track chute 7 is corresponding with lower single track chute 6 in the vertical direction, lower guideway 19 is vertically installed with between inside the base plate of lower double track chute 8 and outside framework 1, upper rail 22 is vertically installed with between inside the top board of upper double track chute 9 and outside framework 1, lower guideway 19 is fixed in inside the base plate of outside framework 1, upper rail 22 is fixed in inside the top board of outside framework 1, the lower double track chute 8 of upper double track chute 9 and its lower position corresponding section all can along corresponding upper rail 22 and lower guideway 19 synchronous slide, the end positions place, side of lower double track chute 8 is respectively arranged with lower block 18, a part for lower block 18 is fixed on lower double track chute 8, another part stretches out lower double track chute 8 along the length direction of lower double track chute 8, the end positions place, side of upper double track chute 9 is respectively arranged with block 23, a part for upper block 23 is fixed on double track chute 9, another part stretches out upper double track chute 9 along the length direction of upper double track chute 9, lower block 18 respectively arranges four on lower double track chute 8, upper block 23 also respectively arranges four on upper double track chute 9, this blackboard also comprises three plate faces 10, each plate face 10 forms by two boards block, the upper following midpoint of the every block plate in each plate face 10 is connected with lower grillage 4 with corresponding loading frame 3 respectively by rotating shaft 21, the position, boundary in each of the lower grillage 4 being positioned at adjacent two boards block is provided with snap close 20, snap close 20 one end is movably installed on corresponding lower grillage 4 side by rotating shaft, and the other end rotates around the shaft and can contact with the position, boundary of corresponding two boards block.The bottom of each lower grillage 4 is provided with roller 5, roller 5 matches with lower single track chute 6 and lower double track chute 8, placement plate face 10 is all embedded between the upper single track chute 7 that lower single track chute 6 is corresponding with position, also placement plate face 10 is embedded between lower double track chute 8 and upper double track chute 9, plate face 10 is arranged on upper single track chute 7 and upper double track chute 9 by loading frame 3, and plate face 10 is arranged on lower single track chute 6 and lower double track chute 8 by lower grillage 4.
Between inside the top board of outside framework 1 and inside base plate, leading screw 16 is installed, the both sides of leading screw 16 arrange a feed rod 17 respectively, between inside the top board that feed rod 17 is also installed on outside framework 1 and inside base plate, leading screw 16 parallels with lower single track chute 6 with the plane at feed rod 17 place, between leading screw 16 and two feed rods 17, blackboard eraser 15 is installed, leading screw 16 and two feed rods 17 are simultaneously through blackboard eraser 15, be threaded connection between blackboard eraser 15 and leading screw 16, the top board arranged outside of outside framework 1 has motor 14, and motor 14 is asynchronous motor.Motor 14 is connected with one end of leading screw 16.Leading screw 16 and feed rod 17 contact with any one lower single track chute 6 and arrange.
The base plate side of outside framework 1 is provided with guide groove 11, guide groove 11 is provided with storage platform 12, and the sidepiece of lower double track chute 8 is provided with handle 13.Guide groove 11 and handle 13 be positioned at lower double track chute 8 homonymy and all with blackboard eraser 15 not homonymy.
During use, because lower double track chute 8 and upper double track chute 9 all have two tracks, so the upper double track chute 9 of lower double track chute 8 and correspondence is slided along lower guideway 19 and upper rail 22, slide into the position that the track of its free time is docked with adjacent lower single track chute 6 and corresponding upper single track chute 7 conllinear, now, just plate face 10 slide handover in the upper single track chute 7 of lower single track chute 6 and correspondence can be come to the track of upper double track chute 9 free time of lower double track chute 8 and correspondence, any exchange of plate face 10 at horizontal level is realized by said method, teacher can allow presently used plate face mediate all the time by unrestricted choice, effectively prevent reflective problem, and explanation and the classmate of being convenient to teacher observe, also can give prominence to the emphasis of teachers' instruction simultaneously, in addition, by the upper double track chute 9 of slide lower double track chute 8 and correspondence, each plate face 10 can also be adjusted and be positioned at same plane, such design makes the present invention's entirety overcome traditional blackboard each piece of plate face not at same plane and the drawback that can only be used alone, each plate face forms one piece of large plate face, each plate both can independently use, and can be used as again overall use, can adapt to the classroom instruction of Large Copacity, many charts preferably.Under sliding the upper double track chute 9 of double track chute 8 and correspondence process in, use handle 13 conveniently can carry out push-and-pull; The upper block 23 of four lower blocks 18 at lower double track chute 8 two ends and four of upper double track chute 9 two ends can lower double track chute 8 and on double track chute 9 slide into while with adjacent lower single track chute 6 and on single track chute 7 concordant time cannot slide again, play positioning action.
As overturn plate face 10, when one end that snap close 20 does not connect with corresponding lower grillage 4 turn to do not contact with plate face 10 time, each plate face 10 overturns by corresponding rotating shaft 21, greatly can expand effective write area of blackboard like this, reduce the number of times that blackboard is cleaned in classroom, " two-sided " function also can realize the reservation of writing on the blackboard long period simultaneously, avoids the Palingraphia of identical content; Rotate snap close 20, make its one end be not connected with corresponding lower grillage 4 turn to the position, boundary of adjacent two boards block in corresponding plate face 10, positioning action fixed head face 10 can be played and make it not rotate.
When needing to wipe the content of having write, switch on power and open asynchronous motor 14, asynchronous motor 14 rotates and drives leading screw 16 to rotate, and realize Double-directional rotary by changing turning to of motor, and then drive movable screw on leading screw 16, drive blackboard eraser 15 to move up and down cleaner plate face.Two feed rods, 17 pairs of blackboard erasers 15 play the guiding role, and make its uniform force, improve the cleaning quality in plate face.
Storage platform 12 is for depositing the classroom such as books, chalk apparatus, and simultaneously it can prolong guide groove 11 and moves left and right, and the position adapted to residing for teacher is conveniently taken at any time.
