Abstract
A hand-cranking writing-wiping integrated blackboard comprises a bracket. A vertical frame of the bracket is vertically arranged on a base, and a first rotating shaft and a second rotating shaft are transversely arranged in the vertical frame in a sliding mode, are parallel to each other, and are in linkage through a chain or a belt. The first rotating shaft or the second rotating shaft is fixedly connected with a rocker shaft, a circle of soft blackboard surrounds the first rotating shaft and the second rotating shaft, and a strip-shaped blackboard eraser is transversely fixed to the vertical frame and makes contact with the surface of the soft blackboard. By the adoption of the structure, when the hand-cranking writing-wiping integrated blackboard is used, the first rotating shaft and the second rotating shaft can be driven to rotate by the rotating shafts so as to well drive the soft blackboard wound on outer rings of the two rotating shafts to rotate, then chalk dust on the surface of the soft blackboard is wiped completely in the rotating process of the soft blackboard through the strip-shaped blackboard eraser which makes contact with the surface of the soft blackboard, the hand-cranking writing-wiping integrated blackboard is easy and convenient to operate, and the wiped chalk dust can be effectively prevented from flying around.
Description
Technical field
The utility model relates to a kind of hand wiping integrated blackboard of writing, and relates in particular to one and is mainly used in classroom, facilitates teacher to impart knowledge to students, and the one that student attends class is write and the integrated blackboard of wiping.
Background technology
Existing blackboard and blackboard eraser are separate type, in the time erasing the board, user must brandish blackboard eraser by a relatively large margin to reach object clean blackboard eraser, easily produces so a large amount of dust in the process erasing the board, and blackboard people around healthy caused to certain threat.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and the hand wiping integrated blackboard of writing of the one providing, it can solve the dust pollution question causing in the process erasing the board, and effectively reduces the dust disorderly wafing everywhere.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of hand wiping integrated blackboard of writing, it comprises support, the stand of support is vertical on base, in stand, laterally slide and be provided with the first rotating shaft and the second rotating shaft, the first rotating shaft and the second shaft parallel also link by chain or belt, and the first rotating shaft or the second rotating shaft are fixedly connected with rocker shaft, are provided with a circle soft blackboard around the first rotating shaft and the second rotating shaft, in stand, be laterally fixed with strip blackboard eraser, the Surface Contact of strip blackboard eraser and soft blackboard.
Above-mentioned the first rotating shaft and the second rotating shaft both ends are provided with tooth, and chain or belt pass through ring gear winding in the first rotating shaft and the second rotating shaft.
While adopting said structure, rotating shaft can drive the first rotating shaft and the second rotating shaft to rotate, thereby well drive the soft blackboard that is looped around two rotating shaft outer rings to rotate, then by making in process that the chalk dust on soft blackboard surface rotates at soft blackboard by wiped clean with the strip blackboard eraser of soft blackboard Surface Contact;
Adopt the first rotating shaft and the second rotating shaft both ends to be provided with tooth, chain or belt are by the structure of ring gear winding in the first rotating shaft and the second rotating shaft, such the first rotating shaft and the second rotating shaft are in the time rotating, and energy is chain drive-belt or belt well, thereby complete the rotation of annular soft blackboard.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the structural representation of Fig. 1 medium-height trestle.
Detailed description of the invention
As shown in Figure 1, a kind of hand wiping integrated blackboard of writing, it comprises support 1, it is upper that the stand 1-1 of support is vertical at base 1-2, laterally slides to be provided with the first rotating shaft 2 and the second rotating shaft 3, the first rotating shafts 2 are parallel with the second rotating shaft 3 and link by chain or belt in stand 1-1, the second rotating shaft 3 is fixedly connected with rocker shaft 4, be provided with a circle soft blackboard 5 around the first rotating shaft 2 and the second rotating shaft 3, on stand 1-1, be laterally fixed with strip blackboard eraser 6, the Surface Contact of strip blackboard eraser 6 and soft blackboard 5.
As shown in Figure 2, the first rotating shaft 2 and the second rotating shaft 3 both ends are provided with tooth, and chain or belt pass through ring gear winding in the first rotating shaft 2 and the second rotating shaft 3.
Adopt said structure, when use, rotating shaft 4 can drive the first rotating shaft 2 and the second rotating shaft 3 to rotate, thereby well drive the soft blackboard 5 that is looped around two rotating shaft outer rings to rotate, in the process of then rotating at soft blackboard by the chalk dust that can make soft blackboard surface with the strip blackboard eraser 6 of soft blackboard Surface Contact by wiped clean, simple operation, can effectively prevent that the chalk dust wiping out from flying upward everywhere.
