Abstract
The utility model discloses a drawing type magnetic blackboard eraser system, comprising: a blackboard, a bar-shaped erasing head, a guide rail at the periphery of the blackboard, rollers disposed at the two ends of the bar-shaped erasing head and rolling in the guide rail, the rollers are controlled by a motor fixed at one side of the blackboard, a switch controlling the motor is disposed at the lower part of the blackboard, the back side of the bar-shaped erasing head is provided with a detachable dust-absorbing box. The blackboard erasing system in the utility model makes blackboard erasing strips move up and down and left and right via the guide rail to erase the blackboard, and can effectively erase chalk trace on the blackboard, during erasing of blackboard, flying of chalk powder will not be caused, and generation of environmental pollution and disease can be reduced. Since direct hand-erasing of blackboard is not required, effect of labour-saving and time-saving can be reached. In addition, the blackboard eraser system in the utility model is also advantaged by solar energy supply, and energy saving.
Description
Technical field
The utility model relates to a kind of blackboard eraser system, particularly relates to a kind of technology and realizes simple, economical and practical drawing and pulling type magnetism eraser system.
Background technology
Culture and education is basic education particularly, mainly finishes on the classroom, and blackboard is the requisite educational aid of classroom instruction.At present, the employed educational aid of school is still based on traditional blackboard, and the wiping method of this blackboard is hand-held blackboard eraser, wiping repeatedly on blackboard.Be subjected to the restriction of blackboard eraser size, the speed that erases the board is slower, and efficient is low, and chalk dust flies upward everywhere, and the human and environment that erases the board is polluted.The healthy hidden danger of having brought that even more serious is to people has increased teacher's the respiratory tract incidence of disease.
In order to improve this teaching environment, a kind of automatic blackboard eraser has appearred in the prior art, for example, the disclosed automatic blackboard eraser of Chinese patent ZL03234113.X, it is equipped with guide frame on the upper and lower both sides of blackboard, and traction electric machine is connected with pulley, and steel wire rope flexibly connects pulley and places in the guide frame, the blackboard eraser of wiping motor is housed places on the guide frame, fan and dust box also are equipped with in the blackboard eraser lower end.There is following shortcoming in such structure: owing to wipe motor, fan and dust box and all be installed on the blackboard eraser, certainly will increase the weight of blackboard eraser, like this blackboard eraser work together very heavy, inconvenience; And this device has also disposed two motors, and complex structure has also increased cost.
The utility model content
At the problems referred to above, main purpose of the present utility model is to provide a kind of drawing and pulling type magnetism eraser system, compare with common automatic blackboard eraser, and the drawing and pulling type magnetism eraser system that the utility model provides, technology realizes simple, economical and practical.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of drawing and pulling type magnetism eraser system, described system comprises: blackboard, bar shaped are wiped head and are arranged on blackboard guide rail on every side, be arranged on bar shaped and wipe the roller that in guide rail, rolls at a two ends, described roller is by being fixed on the Electric Machine Control of blackboard one side, described blackboard below is provided with the switch of control motor, and described bar shaped is wiped head and comprised that the horizontal stripe type is wiped head and the vertical bar type is wiped head.
In one embodiment, described horizontal stripe type is wiped a back side and is provided with dismountable horizontal dust-absorbing box.
In another embodiment, described vertical bar type is wiped a back side and is provided with dismountable perpendicular dust-absorbing box.
In another embodiment, described roller comprises that being installed in the horizontal stripe type wipes first roller at a two ends and be installed in second roller that the vertical bar type is wiped a two ends.
In another embodiment, described motor back connects lead, and the other end of lead is connected with solar panel.
Positive progressive effect of the present utility model is: the drawing and pulling type magnetism eraser system that the utility model provides has the following advantages: the utility model makes the blackboard eraser bar up and down or the move left and right blackboard wiping by guide rail, can effectively wipe the chalk trace on the blackboard, when erasing the board, can not cause flying upward of chalk powder everywhere, therefore can reduce the generation of environmental pollution and disease.Owing to be not directly to go to erase the board, also can reach effect of saving time and labor with hand.In addition, the utility model adopts the solar energy energy supply, has saved the energy.
Description of drawings
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is two of a structural representation of the present utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is one of structural representation of the present utility model, Fig. 2 is two of a structural representation of the present utility model, referring to Fig. 1 and 2, the utility model comprises blackboard 1, bar shaped wiping head and is arranged on blackboard 1 guide rail 3 on every side, be arranged on bar shaped and wipe the roller that in guide rail 3, rolls at a two ends, motor 5 controls of described roller by being fixed on blackboard 1 one sides, blackboard 1 below is provided with the switch 6 of control motor 5, described bar shaped wipe head comprise the horizontal stripe type wipe 10 and the vertical bar type wipe 2, respectively as illustrated in fig. 1 and 2.The horizontal stripe type is wiped 10 back side and is provided with dismountable horizontal dust-absorbing box 11.The vertical bar type is wiped 2 back side and is provided with dismountable perpendicular dust-absorbing box 7, referring to Fig. 2.Roller comprises that being installed in the horizontal stripe type wipes first roller 12 at 10 two ends and be installed in second roller 4 that the vertical bar type is wiped 2 two ends.Motor 5 back connect lead 8, and the other end of lead 8 is connected with solar panel 9.
The utility model makes the blackboard eraser bar up and down or the move left and right blackboard wiping by guide rail, can effectively wipe the chalk trace on the blackboard, when erasing the board, can not cause flying upward of chalk powder everywhere, therefore can reduce the generation of environmental pollution and disease.Owing to be not directly to go to erase the board, also can reach effect of saving time and labor with hand.In addition, the utility model adopts the solar energy energy supply, has saved the energy.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
