Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of multi-functional blackboard.
Background technology
At present, the like product one on market is blackboard, and blackboard is as a kind of teaching aid, and the planar structure that it can repeatedly carry out writing and need not change, the space of a whole page is hard.Surface color mostly is black, white and blackish green.Blackboard is widely used in school, now society, and blackboard is not only only for school, and company, family also have community all to need blackboard, is used for publish information and write blackboard newspaper, also uses blackboard time training course does to employee in company.Each large, medium and small blackboard majority learning education is traditional hard blackboard, artificial erasing chalk word, dust wafts full classroom, cause teachers and students easily to suffer from respiratory disease, damage the healthy of teachers and students, and waste time and energy, affect teaching efficiency, occupy valuable instructional blocks of time, and this original teaching aid and modern education cause incompatible, and do not meet environmental requirement.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of multi-functional blackboard of new structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of multi-functional blackboard improving service efficiency and environmental protection.
Multi-functional blackboard of the present utility model, comprise: blackboard, gear roll device, erasing apparatus and dust collect plant, wherein, gear roll device is arranged on the both sides of blackboard, the plate face of blackboard adopts soft web materials, two the gear roll devices in left and right are connected by gear mechanism, erasing apparatus is arranged on the both sides of blackboard, linked together by connecting rod hold-down mechanism and blackboard, erasing apparatus is bar shaped, dust collect plant is arranged on the bottom of blackboard, by shirking linkage and blackboard links together.
By such scheme, the utility model at least has the following advantages:
Multiple function can be realized, comprising: semi-automaticly to erase the board, automatically collect dust and memory storage function, improve the service efficiency of blackboard, also compare environmental protection.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model multi-functional blackboard.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, a kind of multi-functional blackboard, comprise: blackboard 1, gear roll device 2, erasing apparatus 3 and dust collect plant 4, wherein, gear roll device 2 is arranged on the both sides of blackboard 1, the plate face of blackboard 1 adopts soft web materials, connect two the gear roll devices 2 in left and right by gear mechanism, erasing apparatus 3 is arranged on the both sides of blackboard 1, is linked together by connecting rod hold-down mechanism and blackboard 1, erasing apparatus 3 is bar shapeds, the width of erasing apparatus 3 and the width of blackboard 1 basically identical.Dust collect plant 4 is arranged on the bottom of blackboard 1, by shirking linkage and blackboard 1 links together.Blackboard main body housing is completed by ABS plate (thickness is 4mm).
Operation principle of the present utility model is as follows:
The plate face of blackboard 1 is involved in two the gear roll devices 2 in left and right by the drive of gear mechanism, and by lower link hold-down mechanism and turning handle, when blackboard panel moves, erasing apparatus 3 can by clean for word erasing, and dust is then collected in dust-collecting box.
The utility model can realize following function:
(1) blackboard and blackboard eraser integrated function: bar shaped erasing apparatus and blackboard are combined, width and the blackboard width of erasing apparatus are basically identical.Realizing erase feature by controlling hold-down mechanism, changing traditional sassafras blackboard model into automanual mode.Such as: when the hold-down mechanism controlling erasing apparatus is pressed, erasing apparatus and blackboard close contact, manually rotate rotating handles, drive blackboard cloth to move, make erasing apparatus and blackboard cloth relative motion, thus reach the effect removing word.
(2) chalk powder collecting function: in the dust-collecting box that chalk powder descends slowly and lightly under gravity to blackboard in the middle of the process of writing and wiping writing on the blackboard, thus reach the function automatically can collecting chalk powder.This function can avoid chalk powder in sassafras blackboard process to be scattered everywhere, teacher more can be avoided to suck chalk powder in dais class hour, affect healthy.
(3) memory storage function: blackboard cloth is involved in reel can store a certain amount of word content, rolls out the word content before can checking.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
