Description

A kind of roller-type blackboard being convenient for changing
Technical field
The utility model relates to blackboard for education appliance technology, specially a kind of roller-type blackboard being convenient for changing.
Background technique
Blackboard is that people can be often in contact with the article arrived, and there are mainly two types of the existing blackboards for teaching, the first is It is fixed on metope normal blackboard, second of Reelable blackboard that opposite can be moved up and down being made of two pieces of normal blackboards.The first The posture that blackboard needs writer to adjust oneself deacclimatizes blackboard position, extremely uncomfortable when writing at the top and bottom of blackboard; It needs writer discontinuously to go to push and pull with a hand, and is also required to a hand in writing process and pins blackboard for second, with Prevent it from sliding.In addition, these blackboards need artificial scouring, it is time-consuming and laborious, but also dust from flying can be caused, to teacher There is larger impact with the health of classmates.
Currently, the chalk dust of blackboard seriously affects teaching environment and air quality in conventional teaching, erase the board, both took manually When again it is laborious.And widely used projector in modern teaching, teacher are not easy to the writing on the blackboard on classroom, interactive teaching and learning weakens, And it is not available when powering off.The water of use writes the dustless blank of pen, and light reflection is obvious, be easy to cause asthenopia, erases the board manually, The degree of automation is not high.The LED dust-free blackboard occurred on the market in recent years, manufacturing cost is high, and maintenance cost is also high, and must lead to Electricity could use.Moreover the writing on the blackboard area of the above blackboard is limited, cannot achieve history playback.
Currently, application No. is the Chinese patents of CN201420576997.0 to disclose a kind of double plate faces of auto-manual drum-type Dust environment friendly blackboard, including following eight parts: frame, bottom plate, annular writing on the blackboard adhesive tape, main driven roller, scrubbing brush and dust-collecting box Mechanism, hand crank transmission device, transmission gear for electric motor and holder device.All structures are essentially simple mechanical structure, later maintenance It is convenient and efficient, it is various Mechanism Combination Nover practicals, ingenious in design, realize each body function maximize it is integrated with function;It adopts With the double board face structures of drum-type, space utilization rate is substantially increased;The ash collecting box for being mounted on the blackboard back side can be collected preferably The chalk dust fallen is effectively reduced dust and raises, health environment-friendly;Scrubbing brush and back plate interplanar distance are adjustable, can be according to user itself Need to realize written contents selectivity wiping, it is functional stronger;It allows this work that erases the board to become simple and convenient, and avoids Dependences of many products to power supply, regardless of whether being powered, functional can pass through of the institute of blackboard is all realized manually.
Although the device can be effectively reduced dust and raise, the device is when replacing roller-type blackboard compared with expense Power is unfavorable for quick-replaceable roller-type blackboard.
Based on this, the utility model devises a kind of roller-type blackboard being convenient for changing, to solve the above problems.
