Description

Electronic curling blackboard

Technical field

The utility model relates to a kind of teaching and uses blackboard, particularly a kind of the teaching with the clipboard of blackboard.

Background technology

Teaching is to hang over to be used for teacher's word that writes with chalk in the classroom with blackboard.Blackboard has rectangle frame, and the rectangle frame inside casing has the inclined-plane deckle board, studs with clipboard in the rectangle frame, and there is the composite bed of being convenient to write letter written with chalk on the surface of clipboard.In the prior art, clipboard is the rigid material plate, and the clipboard of rigid material has rigid material plates such as plank, cement plate, glass plate or steel plate.The clipboard area of rigid material is only limited in the rectangle housing, and write area is not very big, is with the manual wiping letter written with chalk of hand-held blackboard eraser during letter written with chalk on the wiping clipboard; Not only time-consuming, effort, in the wiping process, the dust under the wiping flies upward everywhere; Pollute the academic environment in classroom, be harmful to the healthy of Faculty and Students, in addition; Write on the clipboard in the time of will writing again after having expired, wiping part letter written with chalk, although these letter written with chalks are can not keep useful letter written with chalk later on; If want the time spent again, need write pretty troublesome again.

Summary of the invention

The purpose of the utility model is in order to overcome above-mentioned deficiency, proposes that a kind of write area is big, the wiping letter written with chalk is time saving and energy saving, does not pollute to write on classroom environment, the clipboard in front and expired the electronic curling blackboard that can keep a part of letter written with chalk in the time of will writing again behind the word.

The utility model is realized with following method.

Electronic curling blackboard has rectangle frame, and the rectangle frame inside casing has the inclined-plane deckle board, studs with clipboard in the rectangle frame; Clipboard has the lineal hexahedral framework of flat, the lineal hexahedral framework have former and later two big faces vertical with horizontal plane, up and down two levels facet with about two facets vertical with horizontal plane, big of former and later two of lineal hexahedral framework are embedded with backboard respectively; The upper and lower surface of lineal hexahedral framework is connected with the side plate of level respectively, and the two ends of side plate have the left and right sides end plate that stretches out the lineal hexahedral framework respectively and stretch out the back side plate at lineal hexahedral framework rear, up and down first member plate with on the right end plate axis axis hole vertical with horizontal plane arranged respectively up and down; The external diameter roller identical with the thickness of lineal hexahedral framework arranged between left up and down axis hole and the right up and down axis hole; Be connected with the annulus rubber cincture clipboard between the roller of the left and right sides, there is the composite bed of being convenient to write letter written with chalk the outside of clipboard, between the side plate of back the relative blackboard eraser axis hole along the side plate length direction is arranged up and down; Long slab bar shaped blackboard eraser is arranged between the relative blackboard eraser axis hole; There is the blackboard eraser axle that inserts in the blackboard eraser axis hole at the two ends up and down of long slab bar shaped blackboard eraser, and there is shifting shaft in the outside of blackboard eraser upper end, and the shifting shaft of blackboard eraser is connected with the pull bar that stretches out rectangle frame; There are block and handle in the pull bar outer end; The medial surface of shifting shaft blackboard eraser has the blackboard eraser brush, and there is reductor and the motor that links to each other with roller the inboard of bottom in the rectangle frame, and there is dust groove along its length in the outside of bottom in the rectangle frame; The dust groove two ends of rectangle frame both sides have dust groove door respectively; The inclined-plane deckle board of rectangle frame inside casing is the colourless transparent material plate, and illuminating lamp and reflection shield are arranged in the rectangle frame, and there is the switch key of motor and illuminating lamp in the following outside of rectangle frame.

During installation, the utility model need be installed on the metope in classroom and use.

During use, because there is backboard the back of rubber clipboard, the teacher can be with writing letter written with chalk on the clipboard of chalk in rectangle frame; After front clipboard in the rectangle frame was write full word, useable electric moter drove the annulus rubber cincture clipboard and rotates, and forwarded one section of the front clipboard of writing full word to back; One section of the clipboard of the back of not writing forwards in the rectangle frame of front, is used for again that row writes, if the word that the front is write also will be used; Let the annulus rubber cincture clipboard forward to again in the rectangle frame of front, if the word that the front is write is out of use, can be through the pulling pull bar; Let the blackboard eraser brush be attached on the clipboard of back, when the annulus rubber cincture clipboard turned to the back, the letter written with chalk on the clipboard of back can be wiped by the blackboard eraser brush; The blackboard eraser brush is wiped the chalk dust that produces behind the letter written with chalk and can be fallen in the dust groove of bottom in the rectangle frame, regularly opens dust groove door and clears out of the chalk dust in the dust groove, and the inclined-plane deckle board of rectangle frame inside casing is the colourless transparent material plate; In the rectangle frame, illuminating lamp and reflection shield arranged; When ambient light is dark, can turn on lamp, illuminate blackboard, help student viewing.

The clipboard of the utility model is the annulus rubber cincture clipboard, and the usable floor area of clipboard is bigger, can make the word after writing keep a period of time; When wiping the letter written with chalk on the clipboard; Write writing on the blackboard with the driven by motor annulus rubber cincture and rotate, let the blackboard eraser brush that is attached on the clipboard wipe the letter written with chalk on the clipboard, time saving and energy saving; Do not pollute classroom environment, the chalk dust in the dust groove can regularly be removed.

Below in conjunction with accompanying drawing, the utility model is done explanation further.
