Description
Technical field
The utility model relates to teaching aid, is specifically related to a kind of teaching soft board.
Background technology
Calligraphy and the Chinese painting technique of China are of long standing and well established, rich connotation, the conventional teaching exercise needs a large amount of paper of waste, and is difficult to enter on a large scale classroom instruction, mostly existing teaching aid is paper is attached on the blackboard, because people custom is dipped in prepared Chinese ink and write, paints, and the many places pause is often arranged in a process and put forth effort, prepared Chinese ink infiltrates paper easily, pollute blackboard, influence teaching efficiency, used paper also need frequently take off and put, the use of also being inconvenient to impart knowledge to students.
Summary of the invention
The purpose of this utility model is to provide a kind of teaching soft board, can solve simultaneously in the teaching frequently to stick with paper to take off and prepared Chinese ink infiltrates and pollutes the problem that is difficult to enter on a large scale classroom instruction.
For achieving the above object, the technical solution of the utility model is: a kind of teaching comprises with soft board: soft board, pull bar tractive motor, the pull bar rotary electric machine, pull bar, slideway, tooth bar, retracting motor, spool and gear, fixedly install the hanger that is located by connecting above the tooth bar, be spirally connected along the tooth bar length direction below and fixedly install slideway, tooth bar and slideway are fixedly installed on the frame of blackboard, are spirally connected below the pull bar tractive motor to fixedly install the pull bar rotary electric machine and be spirally connected through bearing block and slideway clamp to be slidingly arranged on the slideway, pull bar tractive motor upper end fixedly installs wheel and rack and is meshed, pull bar rotary electric machine lower end arranges pull bar and soft board scrolling stop collar, and an end of soft board is fixedly installed on the pull bar, and retracting motor is fixedly installed on a side of blackboard, retracting motor axle lower end arranges spool, and fixing also can the winding of the other end of soft board is arranged on the spool.
Described spool and seriticker are spirally connected and fixedly install the soft board gag lever post.
The below of described spool fixedly installs fan.
On the described retracting motor shell body is set, fixedly installs the location supporting plate below the motor.
Parcel tray and water storage case are set below the described spool.
The utility model is support with the blackboard for education, owing to be provided with driving rack and slideway, is provided with pull bar tractive motor, pull bar rotary electric machine and retracting motor, and soft board can be launched arbitrarily and withdrawal along the blackboard plane according to the teaching writing needs.
The utility model soft board teaching uses the back rolling to get up, and the fan that the retracting motor spool arranges below can also dry up the water mark, and water does not trickle, do not pollute, but and repeated multiple times use, be suitable in soft pen calligraphy teaching and traditional Chinese Painting are imparted knowledge to students, applying.
Below in conjunction with accompanying drawing the utility model is described in further detail.
