Abstract
The invention relates to a blackboard with an electric eraser. Guide rails are respectively arranged at the two sides of a blackboard body, and are connected with a blackboard eraser transverse rod through sliding blocks, and the blackboard eraser is arranged on the blackboard eraser transverse rod; one side of the blackboard eraser transverse rod is provided with a motor and a friction wheel, and the friction wheel is in rolling friction contact with the outer sides of the guide rails; a central hole of the friction wheel is fixedly connected with an output shaft of the motor, and the other side of the blackboard eraser transverse rod is provided with a pressing wheel; the pressing wheel is in rolling contact with the outer sides of the guide rails, and a pressing wheel pressing and adjusting device is arranged between the blackboard eraser transverse rod and the pressing wheel. The blackboard eraser transverse rod and the blackboard eraser are electrically driven to move up and down to cleanly remove all characters on the blackboard body, and dust absorbing holes are formed in the lower end face of the blackboard body, so that the technical problems that when the chalk characters are erased by the blackboard in the prior art, chalk dust flies everywhere to dirty hands, clothes and face, and the effort is consumed because the arm moves back and forth when erasing the blackboard are solved. The blackboard provided by the invention has the characteristics of convenience in use, labor saving, high removal efficiency, simple structure and the like.
Description
Technical field
The present invention relates to a kind of blackboard, especially relate to a kind of blackboard with electronic wiping board.
Background technology
Existing blackboard eraser is to be made by the material of loading onto felt one class above plank and easily wipe letter written with chalk.When erasing the board, although letter written with chalk has been wiped, chalk dust flies upward everywhere, the hand of making dirty, clothes and face.Arm moves in turn back and forth owing to erasing the board, also sweat very, in addition, when moving in turn back and forth, also strengthen Air Flow, made the farther of diffusion that dust wafts, contaminated environment, long-term suction dust is very unfavorable to student and teacher's physical and mental health, and dust from flying is very unhygienic simultaneously, and the existing blackboard eraser life-span is short, waste of material is serious, does not meet the theory of national energy-saving environmental protection.
Summary of the invention
The present invention will provide a kind of blackboard with electronic wiping board, and this blackboard is easy to use, laborsaving, can remove cleanly the font on blackboard, and elimination efficiency is high, simple in structure.
For achieving the above object, technical scheme of the present invention is: a kind of blackboard with electronic wiping board, comprise blackboard body, blackboard eraser, blackboard body both sides are respectively equipped with guide rail, two side rails connect blackboard eraser cross bar by slide block, above blackboard eraser cross bar, blackboard eraser is housed, blackboard eraser cross bar one side is equipped with motor and friction pulley, friction pulley is connected with guide rail lateral surface rolling friction contact, friction pulley centre bore is fixedly connected with motor output shaft, blackboard eraser cross bar opposite side is equipped with contact roller, and contact roller rolls to contact with guide rail lateral surface and is connected.
The width of blackboard eraser equals the width of blackboard body.Guide rail is T shape guide rail.Releasable connection between blackboard eraser and blackboard eraser cross bar.Contact roller clamping adjustment device is housed between blackboard eraser cross bar and contact roller.Blackboard body lower surface is provided with ash absorbing hole, and ash absorbing hole is communicated with the suction apparatus for ash below being positioned at blackboard body lower surface.
The beneficial effect that the present invention compared with prior art has is: the present invention moves up and down by motorized motions blackboard eraser cross bar and blackboard eraser, just the font on blackboard body all can be disposed cleanly, blackboard body arranges ash absorbing hole on lower surface, solved the blackboard eraser of prior art when wiping chalk word, chalk dust but flies upward everywhere, the hand of making dirty, clothes and face.And the arm technical problem of sweat that moves in turn back and forth while erasing the board, and have easy to use, laborsaving, elimination efficiency is high, the feature such as simple in structure.
Accompanying drawing explanation
Fig. 1 is structural upright schematic diagram of the present invention;
Fig. 2 is structural front view of the present invention;
Fig. 3 is the right cutaway view of Fig. 2;
Fig. 4 is the top view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figures 1 to 4, a kind of blackboard with electronic wiping board, comprises blackboard body 1, blackboard eraser 2, guide rail 3, blackboard eraser cross bar 4, motor 5, friction pulley 6, slide block 7, contact roller 8, contact roller clamping adjustment device 9, ash absorbing hole 10, inhales apparatus for ash 11.
Blackboard body 1 both sides are respectively equipped with guide rail 3, and guide rail 3 is T shape guide rail.Two side rails 3 connect blackboard eraser cross bar 4 by slide block 7, and blackboard eraser cross bar 4 is equipped with blackboard eraser 2 above, and the width of blackboard eraser 2 equals the width of blackboard body 1, releasable connection between blackboard eraser 2 and blackboard eraser cross bar 4.Blackboard eraser cross bar 4 one sides are equipped with motor 5 and friction pulley 6, friction pulley 6 is connected with guide rail 3 lateral surface rolling friction contacts, friction pulley 6 centre bores are fixedly connected with motor 5 output shafts, and blackboard eraser cross bar 4 opposite sides are equipped with contact roller 8, and contact roller 8 rolls to contact with guide rail 3 lateral surfaces and is connected.
Between blackboard eraser cross bar 4 and contact roller 8, contact roller clamping adjustment device 9 is housed.Blackboard body 1 lower surface is provided with ash absorbing hole 10, and ash absorbing hole 10 is communicated with the suction apparatus for ash 11 below being positioned at blackboard body 1 lower surface.
During use, actuating motor 5, makes friction pulley 6 drive blackboard eraser cross bars 4 to move up and down, the font on 1 of blackboard eraser 2 erasing blackboard body etc., and open simultaneously and inhale apparatus for ash 11.When friction pulley 6 skids, by contact roller clamping adjustment device 11, regulate contact roller 8 thrusts, make friction pulley 6 can drive blackboard eraser cross bar 4 to move up and down.
