Description
Technical field
The present invention relates to a kind of multifunctional blackboard for education cleaners.
Background technique
Blackboard is essential tool in tutoring system, and teacher is known by writing letter written with chalk on blackboard to teach student
Know, blackboard just obtains the carrier of knowledge at student, but there is also some defects in use for blackboard, for example, writing full
The letter written with chalk of one blackboard needs quickly to be wiped when carrying out next class, but uses existing blackboard eraser in wiping
There are problems that dust from flying in the process, the respiratory tract being exposed in the environment of dust to child and teacher for a long time and lung
It etc. damaging, and wipes and is stained with more chalk powder in rear blackboard eraser body, be usually used and beaten on blackboard eraser ontology manually
It is cleared up, but chalk powder can directly fly into air and pollute during beaing, unfavorable environmentally-friendly sanitary；In addition, existing
Some blackboard erasers are shorter for height in use there is also not being adjustable highly since structure is relatively simple
Student or teacher for, the use of blackboard eraser is just restricted.
Summary of the invention
In view of the above problems, the present invention is intended to provide multifunctional blackboard for education cleaner, the blackboard cleaner is not
Only have the effect of the dust-proof height that can also adjust blackboard eraser according to different height, it can also be made not when shaking chalk powder
It leaks, centralized collection, use scope is wider, and using effect is more preferable, and practicability is stronger, and environmental protection, health, to also prevent powder
The phenomenon that end may damage student and teacher.
To achieve the goals above, the technical solution adopted in the present invention is as follows:

Preferably, the blackboard eraser ontology front end face is provided with the regulating tank with inverted T-shaped adjusting rod cooperation, the tune
It is machined with the spherical groove of clamping corresponding with each card connection ball in section slot, is adjusted by clamping of the card connection ball in spherical groove
The height of inverted T-shaped adjusting rod.
The beneficial effects of the present invention are: compared with prior art, of the invention thes improvement is that,
Firstly, the present invention designs fixed dust proof member and extension type dust proof member, by fixed dust proof member and can stretch
Contracting formula dust proof member, which combines, surrounds four sides of blackboard eraser body, and chalk powder is not just during erasing chalk end in this way
It can be dissipated away from the surrounding of blackboard eraser body, be enclosed in dust proof member, can be focused on after wiping；Moreover, having cleared up blackboard
Afterwards during clearing up blackboard eraser body, the telescopic adjustment plate in extension type dust proof member is flexed outward and is come, two can stretch
Contracting formula dust proof member end is tightly sealed and is combined by magnetic plate one and magnetic plate two, and two outer both ends pass through fixed dust-proof
Component sealing forms an enclosure space after combining, and beaing blackboard eraser ontology by manual or other components at this time will be in blackboard eraser body
Chalk powder directly beat to above-mentioned enclosure space, centralized collection processing, thus there is no the phenomenons that chalk powder disorderly flies
Occur, it is not only environmentally friendly but also hygienic, it not can cause environmental pollution also；
Secondly, the present invention goes back design height adjusting part, so in use by moving up inverted T-shaped
The purpose of height adjustment can be realized in adjusting rod, and use scope is wide, practical.
