Description

A kind of dust-free black board eraser of efficiency high

Technical field

The utility model is related to realia technical field, especially a kind of dust-free black board eraser of efficiency high.

Background technology

Blackboard is teaching aid essential in school, teacher at school when need to write writing on the blackboard on blackboard, after class The writing on blackboard eraser for student erasing blackboard is needed, is prepared for the teacher of lower class carries out teaching using blackboard, but it is existing In erasing blackboard writing, dust flies away some blackboard erasers everywhere through the bristle of blackboard eraser, the air of teaching is polluted, to using The respiratory system of person has health threat；Sometimes teacher writes full blackboard, and student needs to lift blackboard eraser by the word of whole blackboard Mark is wiped, and erasing area is big, and labour intensity is high, in the prior art can be with the blackboard eraser of dedusting in the presence of some, and blackboard eraser needs to take Charged line or internal setting filter water, using very inconvenient.

The content of the invention

In order to overcome the shortcomings of that existing blackboard eraser is present, the utility model provides a kind of dust-free black board eraser of efficiency high, Erasing area is big, and time saving and energy saving, efficiency of erasing is high, it is to avoid the air in dust pollution classroom dispersed in erase process, to learn It is raw that a good academic environment is provided.

The utility model solves the technical scheme that its technical problem used, a kind of dust-free black board eraser of efficiency high, bag Include blackboard eraser body, handle, upper hopper chute, bristle fixed mount, organ cover, foam-rubber cushion, the first fixed mount, roller, rotating shaft, second consolidate Determine frame, adjusting screw, the 3rd fixed mount and nut, elbow is provided with the top of the blackboard eraser body, the upper hopper chute is fixed At the top of blackboard, the elbow is stuck in inside upper hopper chute, and handle, the blackboard eraser are provided with the outside of the blackboard eraser body Bristle fixed mount is installed on the inside of body, bristle is installed on the bristle fixed mount, be provided with the blackboard eraser body Organ cover, the organ cover is arranged on the surrounding of bristle fixed mount, and the end of the organ cover is provided with foam-rubber cushion, the blackboard The bottom for wiping body is fixed on the first fixed mount, and first fixed mount is U-type groove, and rotating shaft is passed through on first fixed mount Roller is installed with, the roller is placed on the second fixed mount, second fixed mount is Z-type, second fixed mount leads to Adjustment screw and nut is crossed on the 3rd fixed mount, the 3rd fixed mount is fixed on blackboard bottom, the nut-welding It is fixed on the 3rd fixed mount.

The beneficial effects of the utility model are, a kind of dust-free black board eraser of efficiency high, by setting roller and organ cover, sea Silk floss pad and adjusting screw, erasing area are big, and time saving and energy saving, efficiency of erasing is high, it is to avoid the dust pollution dispersed in erase process Air in classroom, for student provides a good academic environment.
