Abstract
A rolling blackboard easily cleaned comprises a support frame (1). A rotating shaft (2) and a rotating shaft (3) are respectively arranged on the upper and the lower ends of the support frame (1). The two ends of the rotating shaft (2) are connected with a driven wheel (4), the two ends of the rotating shaft (3) are connected with a drive wheel (5), and a handle (6) is arranged on the drive wheel (5). An iron sheet blackboard (7) is connected between the driven wheel (4) and the drive wheel (5). Two strip-shaped hairbrushes (8) on the support frame (1) are in contact with one surface of the iron sheet blackboard (7). Chalk dust recovering boxes (9) are arranged under the strip-shaped hairbrushes (8) on the support frame (1). A motor and a reduction gear are arranged on the rotating shaft (3), and the motor and the reduction gear are connected with a switch and a power supply by wires to form a conventional circuit. The utility model has the advantages that as long as the handle is shaked or the motor is started in situ, the drive wheel drives the driven wheel to rotate, the iron sheet blackboard begins to roll, and the blackboard is cleaned by the strip-shaped hairbrushes two times, so the blackboard can be conveniently cleaned; the operation is safe and saves labour, and the cleaning efficiency is high; after the recovering boxes are full, chalk dust can be processed together; the structure is simple, and the blackboard is convenient to use.
Description
Technical field
The utility model relates to the realia technical field, a kind of specifically rolling Easy erasing blackboard.
Background technology
Now teacher teaches, and when erasing the board, chalk dust flies upward everywhere, influences the teaching environment in classroom, simultaneously to teacher and classmate's the healthy adverse influence that causes; The letter written with chalk that has is write De Taigao, and the student often is difficult to cleaning, ascends a height and has potential safety hazard, wastes time and energy, and is very inconvenient.
The utility model content
The purpose of this utility model be design a kind of stand in the original place can be easily thoroughly cleaning, safety labor-saving, rolling Easy erasing blackboard that cleaning efficiency is high.
The utility model rolling Easy erasing blackboard comprises: support 1, support 1 are equipped with rotating shaft 2,3 up and down respectively, and rotating shaft 2 two ends link to each other with driven pulley 4, and rotating shaft 3 two ends link to each other with driving wheel 5, are connected with handle 6 on the driving wheel 5; Be connected with iron sheet blackboard 7 between driven pulley 4 and the driving wheel 5, the two bar shaped hairbrush 8 on the support 1 and the one side of iron sheet blackboard 7 contact, and the below of bar shaped hairbrush 8 is equipped with chalk dust and is reclaimed box 9 on the support 1.
In the rotating shaft 3 motor and speed reducer is housed, motor and speed reducer is connected to a custom circuit by lead and switch, power supply.
The advantage of the utility model rolling Easy erasing blackboard is: stand in the original place and shake handle or start motor, then driving wheel drives the driven pulley rotation, and the iron sheet blackboard begins to roll, the bar shaped hairbrush carries out dual clean to blackboard, can thoroughly clean blackboard, safety labor-saving, cleaning efficiency height easily; After recovery box collection is full, can focus on chalk dust, simple in structure, use very convenient.
