Description
Technical field
This utility model relates to education and instruction device, is specifically related to a kind of Multifunctional blackboard device.
Background technology
Blackboard be one can the plane of repeated writing, it it is the necessary supply of classroom instruction, it is generally adopted what plank or ground glass etc. were made, can write herein above with specific writing materials such as chalks, limited area due to blackboard, and course content is more, it is therefore necessary to constantly use blackboard eraser to clear up blackboard.
For the problem that blackboard wiping is wasted time and energy, the technical scheme of existing many solutions, for instance, the Chinese patent that publication number is CN203460590U discloses a kind of blackboard eraser, it adopts the wiping blackboard structure of entirety, is slided by pulley and blackboard carries out the wiping of disposable entirety, convenient and swift.But it there is problems in that 1) blackboard eraser is structure as a whole, and when the last single cent word of blackboard wiping, this blackboard eraser cannot avoid other need not the word of wiping；2) blackboard eraser takes up room excessive, and its volume is big, produces bigger noise when sliding, affects the carrying out of course.
Utility model content
The purpose of this utility model is in that the above-mentioned technical problem of solution provides a kind of Multifunctional blackboard device, and it can realize the reasonable wiping of blackboard entirety and part, and noise is little, sanitation and hygiene, conveniently use.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Multifunctional blackboard device, including mainboard, the top of described mainboard, bottom is respectively equipped with chute, it is respectively equipped with roller in described chute, described roller is connected to rotating shaft respectively through axis hole, described rotating shaft connects blackboard eraser respectively, lower blackboard eraser, described upper blackboard eraser, lower blackboard eraser is hinged with corresponding described roller, described roller is provided with keyway, described upper blackboard eraser, on lower blackboard eraser, corresponding corresponding described keyway position is provided with retainingf key, described upper blackboard eraser, the surface of lower blackboard eraser is provided with graduation mark, described upper blackboard eraser, the contact surface of lower blackboard eraser and described mainboard is provided with bristle, described upper blackboard eraser, length after the addition of lower blackboard eraser is identical with the height of described mainboard.
Described upper blackboard eraser, lower blackboard eraser are provided with angle-differentiated device with the link of corresponding described roller.
Being provided with ash-pit bottom described mainboard, described mainboard bottom side is provided with collection device.
Described collection device includes chalk placing trough and chalk dust receiving slit.
Described mainboard top is provided with illuminator.
Described chute is convex chute.
This utility model can adjust flexibly, and blackboard is carried out wiping in whole or in part.And this utility model diverse in function, has drawing function, and has other features such as illumination, simple in construction, convenient use.

Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this utility model is not limited to listed embodiment.
Shown in Fig. 1-5, a kind of Multifunctional blackboard device, including mainboard 1, the top, surface of mainboard 1, bottom are respectively equipped with chute 2, are respectively equipped with roller 3 in described chute 2, described roller 3 is provided with axis hole 9, two rotating shafts 4 be separately mounted to correspondence roller axis hole 9 in, described rotating shaft 4 connects blackboard eraser 5 respectively, and described blackboard eraser 5 is two, including upper blackboard eraser and lower blackboard eraser, described blackboard eraser 5 is hinged with corresponding roller 3.
Concrete, described roller 3 is provided with keyway 11, and described blackboard eraser 5 is provided with retainingf key 10 with roller 3 correspondence position.
Described blackboard eraser 5 is rectangle structure, and described blackboard eraser 5 surface is provided with graduation mark 12, can use as drawing rule, and described blackboard eraser 5 is provided with bristle with mainboard 1 contact surface, for wiping mainboard 1 surface.Length after described upper and lower two blackboard erasers 5 additions is identical with the height of mainboard 1, to facilitate the wiping of entirety.
Further, described blackboard eraser 5 is provided with angle-differentiated device (not shown) with roller 3 link, and described angle-differentiated device can arrange the anglec of rotation of blackboard eraser.Described angle-differentiated device can arrange the anglec of rotation of blackboard eraser, coordinates the graduation mark on blackboard eraser, when needing the line segment drawing certain angle and certain length on blackboard, blackboard eraser can be used as drawing rule.
It should be noted that in this utility model, described blackboard eraser is also used as drawing rule and uses.
During use, retainingf key is first made to depart from keyway, it is ensured that the bristle of blackboard eraser, away from mainboard, by blackboard eraser by axis of rotation to required angle, can draw the line segment of certain angle and certain length.
In order to conveniently collect chalk dust, further, being provided with ash-pit 7 bottom described mainboard 1, mainboard 1 bottom side is provided with collection device 8, and described collection device 8 includes chalk placing trough and chalk dust receiving slit, easy cleaning.
Further, described mainboard 1 top is additionally provided with illuminator 6, provides illumination for mainboard 1, it is prevented that when extraneous light is more weak, student does not see blackboard.
Concrete, described chute is convex chute.
When giving lessons, upper and lower two blackboard erasers can being moved to blackboard side, the retainingf key on blackboard eraser is arranged in keyway, and now the bristle on blackboard is adjacent to mainboard.When needing a certain segment word on blackboard wiping, select the upper blackboard eraser of correspondence position with it or lower blackboard eraser, pull out blackboard eraser, make the bristle on blackboard eraser away from mainboard, guarantee will not wipe the word of other parts, now retainingf key departs from the keyway on roller, and when roller rotates, blackboard eraser will not concomitant rotation.Roller and blackboard eraser move along chute, when moving to the position needing wiping, press blackboard eraser, make retainingf key enter in keyway, and bristle is adjacent to mainboard simultaneously, can carry out wiping.After course has carried out, when whole mainboard is required for wiping, two blackboard erasers only need to be moved left and right the wiped clean that can complete entirety.Chalk dust after wiping drops to ash-pit, is collected in chalk dust receiving slit by ash-pit.
This utility model can adjust flexibly, and blackboard is carried out wiping in whole or in part.And this utility model diverse in function, has drawing function, and has other features such as illumination, simple in construction, convenient use.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
