Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
As Figure 1-4, the utility model includes rotational handle 23, top rotating shaft 21, lower rotary shaft 22, backboard 11, biography
Defeated band 12, blackboard curtain 13 (including curtain paper or curtain film), hairbrush 31, chalk dust ledge 32, hairbrush fixed mount 41, blackboard fixed mount 42.
Rotational handle 23 drives the active rotating shaft of lower rotary shaft 22 to rotate by rotating, and coordinates top rotating shaft 21, so that transmission belt 12
Rotation is produced, the blackboard curtain 13 for being close to its surface is rotated together with the rotation of transmission belt 12.Hairbrush 31 is fixed by hairbrush
Frame 42 is fixed on metope, and twice hairbrush 31 is close to blackboard curtain 13 and realizes wiping to blackboard.Chalk dust ledge 32 is whole black
The lower end of plate, the chalk dust after being wiped to hairbrush 31 are collected.The structure of backboard 11 really is fixed on wall by blackboard fixed mount 41
On, make total is solid not rock.
Rotational handle 23 is zigzag handle, is cased with one layer of soft harmless gum material in the outer layer of handle, handle is existed
There is certain comfortableness during use.Rotational handle 23 is connected with rotating shaft realizes that the rotation to transmission belt 12 controls.
The inner side of transmission belt 12 is connected by axis of rotation and rotated with rotating shaft, and the outside of transmission belt 12 and blackboard curtain 13 are tight
Patch, makes blackboard curtain 13 be rotated together with conveyer belt.
Hairbrush 31 has two, and mounting means is up-down structure, the wiping twice of degree of realization blackboard.Hairbrush 31 is consolidated by hairbrush
