A teaching board, which is an instrument used for writing and demonstrating in the education industry, is a board surface generally placed in a classroom or a meeting room, and is used for writing contents with chalk or a water pen to play a role in explaining and demonstrating. In the teaching process, as the number of blackboard-writing is large, the teacher is limited by the limitation of the area of the teaching board in the process of writing the blackboard-writing, and the blackboard-writing is continued after the teaching board is completely written with the blackboard-writing and needs to be erased, so that the teaching efficiency is influenced, and on the other hand, the students cannot record the notes in time.
In view of this, an embodiment of the present invention provides a whiteboard for teaching, in which two ends of a flexible writing board are respectively wound on a first rotating shaft or a second rotating shaft, and synchronous rotation of the first rotating shaft and the second rotating shaft can be achieved by using a transmission assembly connected to the first rotating shaft and the second rotating shaft, so that the flexible writing board can be wound or unwound, erasing of handwriting on the flexible writing board is avoided, and continuous writing of a user is ensured. Meanwhile, the student can review the blackboard writing on the flexible writing board, and recording is facilitated.
In order to better understand the technical scheme, the technical scheme is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a whiteboard for teaching according to an embodiment of the present invention includes:
a frame 10, the frame 10 being formed with a writing window;
the flexible writing board 30 is movably arranged in the writing window and is provided with a first end and a second end which are arranged in the length direction;
the scroll assembly comprises a first rotating shaft 21 and a second rotating shaft 22 which are arranged in the writing window and are arranged at intervals along the length direction of the flexible writing board 30, the first rotating shaft 21 and the second rotating shaft 22 are both rotatably connected to the frame 10, the first end of the scroll assembly is wound on the peripheral surface of the first rotating shaft 21, and the second end of the scroll assembly is wound on the peripheral surface of the second rotating shaft 22; and
the transmission assembly 40, the transmission assembly 40 connects the first rotating shaft 21 and the second rotating shaft 22, and drives the first rotating shaft 21 and the second rotating shaft 22 to rotate synchronously, so that the first rotating shaft 21 and the second rotating shaft 22 select one to wind the flexible writing board 30, and another one is selected to unwind the flexible writing board 30, thereby realizing that the flexible writing board 30 slides in the writing window, and the tensioning is between the first rotating shaft 21 and the second rotating shaft 22, so as to adjust the writing position of the flexible writing board 30 corresponding to the writing window.
In the technical solution adopted in this embodiment, a fixed reel assembly can be conveniently installed through the arranged frame 10, the first end and the second end of the flexible writing board 30 are respectively wound around the first rotating shaft 21 and the second rotating shaft 22, the length of the flexible writing board 30 is greater than the distance between the first rotating shaft 21 and the second rotating shaft 22, when a user writes in a writing window, the portion of the flexible writing board 30 corresponding to the writing window is fully written, then the first rotating shaft 21 or the second rotating shaft 22 is rotated, under the driving of the transmission assembly 40, the first rotating shaft 21 and the second rotating shaft 22 synchronously rotate, one of the first rotating shaft 21 and the second rotating shaft 22 is enabled to wind the flexible writing board 30, the other one is enabled to unwind the flexible writing board 30, the flexible writing board 30 is enabled to slide relative to the writing window, and accordingly the fully written portion of the flexible writing board 30 corresponding to the writing window is wound on the first rotating shaft 21 or the second rotating shaft 22, simultaneously, the blank part of the flexible writing board 30 is arranged in the writing window, so that the user is prevented from erasing the handwriting on the flexible writing board 30, the user can continuously write, and the teaching efficiency is improved. In addition, the flexible writing board 30 with written full writing is rolled on the first rotating shaft 21 or the second rotating shaft 22, so that the teaching content can stay on the flexible writing board 30 for a long time, and students can rotate the first rotating shaft 21 or the second rotating shaft 22 in the opposite direction to check the rolled flexible writing board 30 with written full writing, thereby being more beneficial to the students to copy records and master the content of the taught knowledge, and improving the teaching quality.
