Wheel composition.
No. two described guide wheel groups are the separate guide wheel composition of two rows, often arrange guide wheel and separate are led by several
Wheel composition.
Described support material is aluminium alloy.
Described front connecting rod is identical with back side length of connecting rod, and two connecting rods are also equal with the angle of plane where blackboard.
Described positioning blackboard eraser is constituted for nonmagnetic substance, and magnetism eraser is constituted for magnetic material.
Two gear shafts in described gear train are fixed together by connecting rod.
Described blackboard guide rail both sides are for a grooved tracks for guide wheel group guide wheel movement.
Described support guide is up and down for No. two grooved tracks of guide wheel group guide wheel movement.
The utility model locally eliminates the effect of writing in order to reach, while reaching front control blackboard eraser,
The blackboard eraser that the reality at the back side plays effect can work simultaneously, while reaching action synchronization, using light.
This kind of dust-free blackboard defines moving up and down for blackboard eraser by the blackboard guide rail of blackboard both sides, by support top
Support guide define moving left and right for blackboard eraser, while used guide wheel group in two guide rails, when improve mobile
Stability, the phenomenon of interim card is reduced, when the spring fixedly mounted in blackboard guide rail can mitigate user and move up and down
Required strength, its reason is that spring can provide upward elastic force during moving up, during moving down
The weight of support can provide the elastic force of downward dynamic balance spring, and the use of gear train can guarantee that the motion of front and rear blackboard eraser is same
Step, the use of spring support enables blackboard eraser to be resetted when not using, and enables magnetic blackboard eraser away from blackboard, by
Other writings are not influenceed to become a reality with the use of while making local elimination writing in above all parts.

Specific embodiment
The utility model is further described below in conjunction with Figure of description and specific preferred embodiment.
A kind of dust-free blackboard, it is characterized in that：Including blackboard 1, support and blackboard eraser bindiny mechanism, described blackboard 1 is interior
There is the magic blackboard of iron powder in portion, and the described both sides of blackboard 1 are provided with support guide 2, and described support both sides are fixed with and blackboard
The support supporting leg 3 that the width of guide rail 2 matches, the lower end of two described side stand supporting legs 3 is installed with spring pad 5, described
The top of spring pad 5 is provided with a guide wheel group 4, and two described tops of support supporting leg 3 are connected by support guide 6, and described is black
Blackboard eraser bindiny mechanism is made up of a pair of pitch wheel groups 7, and two gears of described gear train 7 are respectively fixedly connected with company
Front connecting rod 8 and back side connecting rod 9 are connected to, described front connecting rod 8 and back side connecting rod 9 pass through spring support 12 and No. two guide wheels
Group 13 is connected, and No. two described guide wheel groups 13 are located between front connecting rod 8 and back side connecting rod 9, described one end of spring support 12
It is hinged with No. two guide wheel groups 13, the other end is fixedly connected with connecting rod, described front connecting rod 8 is fixed with away from the one end of gear train 7
Positioning blackboard eraser 10, described back side connecting rod 9 is fixed with magnetism eraser 11, described support supporting leg 3 away from the one end of gear train 7
