Abstract

The utility model discloses a to the improvement of the fixed teaching blackboard of traditional plank, especially to use to the teaching, the writing on the blackboard information quantity is various, classroom blackboard that the information updating is fast. Mo biwusi takes dust free blackboard wipes including top cap, pivot, mo biwusi area, lower extreme dust collecting tank, spiral conveyer belt, plate washer and the sponge of installing on the baffle, the top cap is connected with the pivot through the pulley hole, nested mo biwusi area is and can drive the rotation of mobiwusi area in the pivot, mo biwusi area meet with lower extreme dust collecting tank, lower extreme dust collecting tank installs the spiral conveyer belt inside, the plate washer fix the top cap on, install sponge on the plate washer wipe with mo biwusi take in close contact with, the pivot lower extreme pass through the pulley hole and be connected with lower extreme dust collecting tank. It has changed traditional blackboard and has born the drawback that the information quantity is little, clean blackboard inconvenience, dust harm and the use of face single face.

Description

Mobius Strip dust-free blackboard

Technical field

The utility model is the improvement to the blackboard for education that conventional wood panels is fixed, and especially use for teaching, writing on the blackboard information content is various, the classroom blackboard that information updating is fast.

Background technology

The blackboard that current teaching uses is all the fixing composite panel motionless on the wall of tradition, usually to attend class writing on the blackboard for teacher.But conventional wall hanging black board also exists many deficiencies: one be common size blackboard carrying information content little; Two be use all with scrubbing brush by blackboard eraser wash clean, could continue to write; Three is when erasing the board, and not only wastes time in classroom, and the dust danced in the air can affect the healthy of teachers and students and classroom health.Meanwhile, traditional blackboard effectively can only utilize wherein one side.

Utility model content

The utility model is intended to solve the problem, and provides a kind of Moebius dust-free blackboard, it change traditional blackboard beared information amount little, clean blackboard inconvenience, drawback that dust harzard and plate face one side use, its technical scheme adopted is as follows:

Mobius Strip dust-free blackboard comprises: top cover 7, rotating shaft 1, Mobius Strip 4, dust collecting groove 3, screw transmission strap 2, plate washer 6 and sponge brush 5, described top cover 7 is connected with rotating shaft 1 by pulley hole, nested Mobius Strip 4 in described rotating shaft 1 and Mobius Strip 4 can be driven to rotate, described Mobius Strip 4 connects with lower end dust collecting groove 3, the in-built screw transmission strap 2 of described lower end dust collecting groove 3, described plate washer 6 is fixed on described top cover 7, described sponge brush 5 and described Mobius Strip 4 close contact, described rotating shaft 1 lower end is rotationally connected by pulley hole and lower end dust collecting groove 3, the outlet 8 of cleaning dust is fixed in the two ends of dust collecting groove.

On the basis of technique scheme, described rotating shaft 1 is that two symmetries are installed on plate washer 6 two ends, and sponge brush 5 is fixed on plate washer 6, and the runner that screw transmission strap 2 is socketed on plate washer 6 lower end is rotationally connected.

On the basis of technique scheme, the steel frame construction that described Mobius Strip 4 built-in hinge connects, supports Mobius Strip 4.

The utility model tool has the following advantages: structure is simple, easy to use, can carry more information, after writing, promote rotating shaft, the content of writing can be automatically brought to plate washer rear, namely can rotate backward, the content of writing before finding, also can continue to use, the sponge brush on baffle plate can remove chalk writing automatically, and not returned dust harzard, the blackboard space of a whole page is fully utilized.

Symbol description

1. rotating shaft, 2. screw transmission strap, 3. dust collecting groove, 4 Mobius Strips, be 5. arranged on plate washer sponge brush, 6. plate washer, 7. top cover, 8. clear up dust outlet.

Detailed description of the invention

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As shown in Figure 1, Figure 2, Figure 3 and Figure 4:

Preferably, described rotating shaft 1 is that two symmetries are installed on plate washer 6 two ends, and sponge brush 5 is fixed on plate washer 6, and the runner that screw transmission strap 2 is socketed on plate washer 6 lower end is rotationally connected.

Preferably, the steel frame construction that described Mobius Strip 4 built-in hinge connects, supports Mobius Strip 4.

In use, promote the 4 Mobius Strip blackboard spaces of a whole page and rotate, the new untapped blackboard space of a whole page is rotated out.When clearing up blackboard, rotate 2 screw transmission straps, inner break flour will be pushed out, focus on.

The utility model structure is simple, easy to use, can carry more information, after writing, promote rotating shaft, the content of writing can be automatically brought to plate washer rear, namely can rotate backward, the content of writing before finding, also can continue to use, the sponge brush on baffle plate can remove chalk writing automatically, and not returned dust harzard, the blackboard space of a whole page is fully utilized.

Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
