Description
Technical Field
The invention relates to an educational facility, in particular to a classroom special blackboard which can attract and fix a left writing board and a right writing board by a magnet, and draw back the writing boards by a tension spring when being disassembled, thereby achieving the purpose of quick reset and convenient movement and positioning.
Background
The movable blackboard installed in the classroom at present often can not push away the position during use, and the power of use is too big can bounce back, and the power of use is too little can not push away the position again, need push away the second time, and is very troublesome like this. If the two blackboards can not be pushed to the positions, the display screen at the back of the middle part can be exposed, so that the two blackboards are not only ugly, but also the effect of the students on seeing the blackboards can be influenced.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a blackboard special for classrooms, which can attract and fix a left writing board and a right writing board by a magnet, and can be quickly reset by pulling back the writing boards by a tension spring during disassembly.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a convenient special blackboard in classroom that removes and fix a position, which comprises a frame, the display screen has been put in the middle of the frame, the track has been put to the frame below, the frame left part has been put left clipboard, the frame right part has been put right clipboard, right clipboard bottom installation right pulley, right pulley installs in the track right part, right extension spring has been put to track right part below, right extension spring one end is fixed at the track right-hand member, right magnet is fixed to the right extension spring other end, right magnet passes through right connecting block fixed connection in the lower left corner at right clipboard, left clipboard bottom installation left pulley, left pulley installs in the track left part, left extension spring has been put to track left part below, left extension spring one end is fixed at the track left end, left magnet is fixed at the left side of left extension spring other end, left magnet passes.
The movable blackboard has the advantages that the movable blackboard can be conveniently used, the left writing board and the right writing board can be attracted and fixed by the magnets only by exerting force when in use, and the trouble that the writing boards bounce back when the force is too large, cannot be pushed to the position when the force is too small and needs to be pushed for the second time can be avoided. When the left writing board and the right writing board are disassembled, the tension spring can pull the writing board back to the original position by separating the two magnets with force, so that the writing board can be reset quickly. Therefore, the movable blackboard is very convenient and practical to use.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a block diagram of a first embodiment of the present invention.
In the figure: 1. the multifunctional pen comprises a frame, 2 parts of a display screen, 3 parts of a left writing board, 4 parts of a right writing board, 5 parts of a track, 6 parts of a left tension spring, 7 parts of a left pulley, 8 parts of a left magnet, 9 parts of a left connecting block, 10 parts of a right connecting block, 11 parts of a right magnet, 12 parts of a right pulley and 13 parts of a right tension spring.
Detailed Description
In the embodiment shown in fig. 1, a frame (1), a display screen (2), a left writing board (3), a right writing board (4), a track (5), a left tension spring (6), a left pulley (7), a left magnet (8), a left connecting block (9), a right connecting block (10), a right magnet (11), a right pulley (12) and a right tension spring (13) are provided.
The invention relates to a classroom special blackboard convenient to move and position, which comprises a frame (1), wherein a display screen (2) is arranged in the middle of the frame (1), a track (5) is arranged below the frame (1), a left writing board (3) is arranged at the left part of the frame (1), a right writing board (4) is arranged at the right part of the frame (1), a right pulley (12) is arranged at the bottom of the right writing board (4), the right pulley (12) is arranged at the right part of the track (5), a right tension spring (13) is arranged at the lower right part of the track (5), one end of the right tension spring (13) is fixed at the right end of the track (5), a right magnet (11) is fixed at the other end of the right tension spring (13), the right magnet (11) is fixedly connected with the lower left corner of the right writing board (4) through a right connecting block (10), a left pulley (7) is arranged at the bottom of the left writing board (3), a left pulley (7) is arranged at, left extension spring (6) one end is fixed at track (5) left end, and left magnet (8) are fixed to left extension spring (6) other end, and left magnet (8) pass through left connecting block (9) fixed connection in the lower right corner of left clipboard (3).
