The utility model is composed of a flexible blackboard, a bracket, a big gear, a driving wheel, etc. The utility model is characterized in that both ends of the bracket are axially connected with the driving wheel and a driven wheel, the driving wheel and the driven wheel are sheathed with the flexible blackboard, the driving wheel is connected with a motor shaft, the driving wheel is fixedly connected with the big gear, the big gear is engaged with three small gears, shafts of small gears of both sides are respectively and fixedly connected with a word erasing drum, and a shaft of the small gear of the middle is fixedly connected with a dust removing rolling wheel. The utility model has the advantages of simple structure, low cost, convenient use, automatic blackboard erasion, no chalk dust, no noise, sanitation and cleanness and teaching effect improvement.
Description
The utility model relates to a kind of driven blackboard, relates to a kind of having of rotation of can circulating automatically specifically and wipes the flexible blackboard that word goes to powder mechanism, is the instrument of usefulness of imparting knowledge to students in the classroom such as large, medium and small school, belongs to teaching equipment.
At present, the blackboard great majority of teaching usefulness still are traditional fixed hard blackboard in each large, medium and small classroom, the use chalk is write, chalk dust long-term pollution classroom, cause teachers and students easily to suffer from respiratory disease, diminish the healthy of teachers and students, fixed hard blackboard surface on the sort of wall, must constantly remove to write, go writing on the erasing blackboard at any time with hand during teaching, waste time and energy like this, influence teaching efficiency, taken valuable instructional blocks of time, existing this original teaching means and modern education cause are incompatible.
The purpose of this utility model is to design wipes the flexible blackboard that word goes to powder mechanism having of a kind of rotation that can circulate automatically, to overcome the deficiencies in the prior art, reaches easy to use, cleaning, health, teaching of high efficiency purpose.
The purpose of this utility model is to realize like this, it is mainly by flexible blackboard (1), support (2), gear wheel (3), driving wheel (4), wipe word cylinder (5), pinion (6), remove powder roller (7), driven pulley (8), right outer cover parts such as (9) are formed, the two end axles that it is characterized in that support (2) is connected to driving wheel (4) and driven pulley (8), be with flexible blackboard (1) on driving wheel (4) and the driven pulley (8), driving wheel (4) is coupling with motor, be connected with gear wheel (3) on the driving wheel (4), gear wheel (3) and three pinions (6) engagement, respectively be connected with on the axle of the pinion of both sides (6) and wipe word cylinder (5), be connected with powder roller (7) on the axle of intermediate speed pinion (6), and go the powder roller (7) and the wiping word cylinder (5) of both sides to be abutted against, two surfaces of wiping word cylinder (5) and flexible blackboard (1) near, be provided with cap (10) above the support (2), be provided with down cap (11) below the support (2), the left side of support (2) is provided with left outer cover (12), be provided with left operation panel (14) in the left side outer cover (12), support i2) the right side is provided with right outer cover (9), is provided with right operation panel (13) in the right outer cover (9).
Its feature is that also the right-hand member of support (2) also is provided with adjuster (15), can regulate distance between driven pulley (8) and driving wheel (4) by adjuster (15).
Its feature is that also the bottom of left outer cover (12) is provided with meal outlet (16).
Its feature also is vertically to be provided with in the flexible blackboard (1) reinforcement (17).
The utility model is compared with prior art: it is simple in structure, and is with low cost, easy to use, erasing blackboard automatically, and no dust, noiselessness, sanitation and hygiene can improve teaching efficiency, are a kind of desirable driven blackboards.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is analysed and observe the plan structure schematic diagram for the big portion of the utility model.
Accompanying drawing 2 is the utility model overall appearance front view.
Accompanying drawing 3 is a laterally section structure schematic diagram of the utility model parts flexible blackboard (1).
Wherein: 1, flexible blackboard, 2, support, 3, gear wheel, 4, driving wheel, 5, wipe the word cylinder, 6, pinion, 7, remove the powder roller, 8, driven pulley, 9, right outer cover, 10, go up cap, 11, cap down, 12, left outer cover, 13, right operation panel, 14, left operation panel, 15, adjuster, 16, meal outlet, 17, reinforcement.
Referring to accompanying drawing: the utility model it mainly by flexible blackboard (1), support (2), gear wheel (3), driving wheel (4), wipe word cylinder (5), pinion (6), remove powder roller (7), driven pulley (8), right outer cover parts such as (9) are formed, the two end axles that it is characterized in that support (2) is connected to driving wheel (4) and driven pulley (8), be with flexible blackboard (1) on driving wheel (4) and the driven pulley (8), vertically be provided with reinforcement (17) in the flexible blackboard (1), the right-hand member of support (2) also is provided with adjuster (15), can regulate distance between driven pulley (8) and driving wheel (4) by adjuster (15), to change the tensioner degree of flexible blackboard (1), driving wheel (4) is coupling with motor, motor belongs to prior art, repeats no more here.Be connected with gear wheel (3) on the driving wheel (4), gear wheel (3) and three pinions (6) engagement, respectively be connected with on the axle of the pinion of both sides (6) and wipe word cylinder (5), be connected with powder roller (7) on the axle of intermediate speed pinion (6), and go the powder roller (7) and the wiping word cylinder (5) of both sides to be abutted against, two surfaces of wiping word cylinder (5) and flexible blackboard (1) near, after being driven by driving wheel (4) by pinion (6), word cylinder (5) can effectively wipe the lip-deep writing of flexible blackboard (1) so that wipe, be provided with cap (10) above the support (2), be provided with down cap (11) below the support (2), the left side of support (2) is provided with left outer cover (12), be provided with left operation panel (14) in the left side outer cover (12), the bottom of left side outer cover (12) is provided with meal outlet (16), the right side of support (2) is provided with right outer cover (9), be provided with right operation panel (13) in the right outer cover (9), can control flexible blackboard (1) by left operation panel (14) and right operation panel (13) moves horizontally, when the space of a whole page of flexible blackboard (1) moved horizontally, the word on the panel can be wiped word cylinder (5) by two and wipe automatically.When running into when having a power failure, flexible blackboard (1) still can work as the normal blackboard use, in addition flexible blackboard (1) above, two fluorescent lamps also can be installed, so that the writing on the flexible blackboard (1) is seen clearlyer on the last cap (10).
