Description
Technical field
The utility model relates to the blackboard for education of teaching instrument field.
Background technology
At present, blackboard is divided into fixed blackboard and sliding blackboard, fixed blackboard writing limited area, and write area equals to account for wall area substantially; Sliding blackboard, although write area is large, account for wall area also very large, write area also equals to account for wall area substantially, and in multi-media classroom or the less classroom of area cannot use.
Have a kind of blackboard of flexibility at present, when writing, easily there is indent in flexible blackboard, writes and have some setbacks.
Summary of the invention
The utility model object is: provide a kind of blackboard for education, can obtain the write area that twice accounts for wall area, when writing, indent can not occur.
Technical solution of the present utility model is:
Blackboard for education, its special character is: comprise blackboard framework, endless belt conveyer formula panel, left rotary shaft, right spindle, motor and swab, described blackboard framework is surrounded by upper side frame, lower frame, left frame, left frame; Described left rotary shaft, right spindle lay respectively at left frame, the left frame place of blackboard framework, and described endless belt conveyer formula panel encases two rotating shafts, and described motor drives endless belt conveyer formula panel to do cyclic transfer motion by left rotary shaft and right spindle;
Described endless belt conveyer formula panel itself is provided with the pusher of support panel with endless belt conveyer formula panel parallel and support panel; The pusher of described support panel promotes support panel and moves forward and backward along the direction perpendicular to support panel place plane;
Described swab comprises water leg, flusher, Wiper blade, baker, described water leg is between the lower edge and lower frame of endless belt conveyer formula panel, described flusher is between left frame and left rotary shaft, and spray direction perpendicular to left rotary shaft, described Wiper blade is positioned at the rear plate face of endless belt conveyer formula panel and is parallel to left rotary shaft, described baker is positioned at the right of Wiper blade, and baker is towards right spindle;
The right-hand member of described water leg is provided with dewatering outlet, and the right-hand member of described water leg and the lower frame of blackboard framework pass through pinned connection.
The distance in above-mentioned Wiper blade and left rotary shaft axle center is L1, and the distance in left rotary shaft axle center and right spindle axle center is L2,0 < L1≤1/3L2.
Sponge adhesive tape is also provided with between above-mentioned flusher and Wiper blade.
Above-mentioned pusher comprises electric cylinder and push rod, described push rod be positioned at endless belt conveyer formula panel inside and with endless belt conveyer formula panel parallel, described electric cylinder promotes push rod and seesaws.Described push rod quantity is 4, is distributed in the edge of endless belt conveyer formula panel, and support panel can be moved forward and backward stably.
The utility model has the advantages that:
(1) setting of support panel, when writing, support panel moves forward, and fits, play a supporting role with the front panel of endless belt conveyer formula panel, when writing, indent can not occur; When needing mobile annular conveyor type panel, support panel moves backward, reduces the friction between mobile annular conveyor type panel, extends the service life of endless belt conveyer formula panel.
(2) flusher is between left frame and left rotary shaft, reduces the occupation of land space, front and back of blackboard, and is easy to overhaul flusher.
(3) when needs draining, the left end of water leg can be lifted, open the dewatering outlet of right-hand member, sewage is discharged from the dewatering outlet of right-hand member, and waterproof and cleaning are conveniently.
