Abstract
The invention discloses an adjustable blackboard which comprises a blackboard main body, an adjusting rod, a motor I, an adjustable blackboard eraser, a motor II and a groove, wherein the adjusting rod is fixedly mounted on the blackboard main body; the motor I is connected with the adjusting rod; the adjustable blackboard eraser is mounted on the blackboard main body; the motor II is connected with the adjustable blackboard eraser; the groove is mounted at the bottom end of the blackboard main body. The adjustable blackboard has the beneficial effects that the adjusting rod is used for adjusting the angle of the blackboard, the groove is arranged at the bottom of the blackboard, and falling dust caused by wiping the blackboard falls into the groove at the bottom along the angle of the blackboard, so that the work of cleaning the dust becomes simple and convenient, and the adjustable blackboard eraser is driven to work by the motor and moves up and down on the blackboard, so that the purpose of wiping the blackboard is achieved, the intelligence of the blackboard is realized, and the requirement of the modern society is met.
Description
Technical field
The present invention relates to a kind of blackboard, relate in particular to a kind of adjustable blackboard, belong to adjustable blackboard field.
Background technology
Before word invention, it is found that charcoal can draw a picture, in some ancient times in Europe, in grotto, can find some mural paintings in ancient times, the crag of drawing these mural paintings can be called blackboard from traditional sense.The multiplex a kind of article that are known as sand table of ancient Chinese teaching, with hardwood repeated writing on sandy soil, but since the soft property of sandy soil, a kind of blackboard when it can not be interpreted as.Middle Ages; it is found that lime and water are mixed and made into block; by the method that is similar to charcoal pencil, at the hard article surface of dark color, write; to 19th century; people are with the pitch-dark plank surface that is coated in; with protection plank, be not etched, the Main Function of blackboard is not teaching at that time certainly, until mid-term in 19th century, just all over the world, school came into vogue.
Over more than 200 year, blackboard from the earliest with blacking, spread upon plank, the hard objects surfaces such as cement, water mill glass to the nineties, present color coated steel sheet, the witnesses such as composite panel the development step by step of world's educational undertaking, for the mankind convey knowledge and distinctions won on the battlefield have been made in universal education.Now, it is various that the kind of blackboard also starts the complexity that becomes, from color minute, has blackboard, green plate, blanks etc., have surface plate from surface configuration minute, cambered plate, from structure, forming to divide has support portable plate, draw back plate, lifter plate, magnet board, has blackboard for education from purposes minute, office blank, billboard, Graphic Panel.And blackboard for education has electronic blackboard, Multifunctional combined board, combination push-and-pull blackboard, interactive electric whiteboard, band curtain projection plate etc.Blackboard not refers in particular to the plate face of black, in traditional sense, say it be one can repeated writing plane, plate face is hard, is used for teaching.Although and existing blackboard is of a great variety, when erasing the board, the dust falling falls to the ground or blackboard bottom, be inconvenient to clear up, and general blackboard all needs artificial wiping, do not meet the demand in Modern Information based epoch.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of adjustable blackboard, uses simply, and cleaning dust is convenient, and meets the demand of Modern Information based Society.
To achieve these goals, the technical solution used in the present invention is: a kind of adjustable blackboard, comprise blackboard body, adjusting rod, motor I, adjustable blackboard eraser, motor II and groove, adjusting rod is fixedly mounted on blackboard body, motor I is connected with adjusting rod, adjustable blackboard eraser is arranged on blackboard body, and motor II is connected with adjustable blackboard eraser, and groove is arranged on the bottom of blackboard body.
Further, described blackboard body is composite plate.
Further, described motor is threephase asynchronous.
The invention has the beneficial effects as follows: use adjusting rod to regulate the angle of blackboard, in blackboard bottom, groove is set, the dust that falls of erasing the board can fall into along the angle of blackboard the groove of bottom, thereby make the work of clearing up dust become simple and convenient, the function of adjustable blackboard eraser is utilized its work of driven by motor exactly, makes it the moving up and down of blackboard, thereby reaches the object erasing the board, realize the intellectuality of blackboard, met the demand of modern society.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, blackboard body, 2, adjusting rod, 3, motor I, 4, adjustable blackboard eraser, 5, motor II, 6, groove.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of adjustable blackboard, comprise blackboard body 1, adjusting rod 2, motor I 3, adjustable blackboard eraser 4, motor II 5 and groove 6, adjusting rod 2 is fixedly mounted on blackboard body 1, motor I 3 is connected with adjusting rod 2, adjustable blackboard eraser 4 is arranged on blackboard body 1, and motor II 5 is connected with adjustable blackboard eraser 4, and groove 6 is arranged on the bottom of blackboard body 1.
Described blackboard body 1 is composite plate.
Described motor I 3 is threephase asynchronouses.
During use, while erasing the board, open motor I 3, drive adjusting rod 2 to rotate, blackboard body 1 is adjusted to suitable angle, then erase the board, make like this dust under wiping drop to automatically in the groove 6 of blackboard body 1 bottom, it is simple and convenient that cleaning work becomes; In addition except manual type erases the board, but also can use motor II 5 to drive adjustable blackboard erasers 4 that adjustable blackboard eraser 4 is moved at the upper and lower side of blackboard body 1, save manpower, more meet the demand of modern society.
