DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3The utility model provides a technical solution: a teaching flip writing board, comprising a fixed column 1, a plurality of writing boards 2, a carrier board 3 and a frame board 4, the number of the fixed columns 1 is two, one side of the bottom plate of the fixed column 1 is connected to the carrier board 3, the other side of the bottom plate of the fixed column 1 is connected to the frame board 4, the frame board 4 and the carrier board 3 are horizontally symmetrical about the fixed column 1, an annular hinge shaft 5 is installed between the two fixed columns 1, the writing board 2 is rotatably connected to the fixed column 1 through the annular hinge shaft 5, a rotating ring 6 is embedded in the fixed column 1, a limiting rod 8 is fixedly installed on the rotating ring 6 through a connecting block 7, the limiting rod 8 is a telescopic sleeve structure, the top end of the connecting block 7 is rotatably connected with a spring U-shaped tube 9, and a plurality of jacks 10 are opened on the outer surface of the fixed column 1 along the circular edge;
[0018] A rectangular notch is opened inside the frame plate 4, and a slide groove 11 is arranged on the inner wall of the rectangular notch. A film roll 12 is fixedly installed on the outer side of the frame plate 4, and a double-sided tape 13 is attached to the surface of the film on the film roll 12. The film on the film roll 12 is pulled out in the slide groove 11 of the rectangular notch toward the fixed column 1, and a cutting mechanism is arranged at the edge of the frame plate 4 close to the film roll 12;
[0019] The cutter mechanism includes a cutter mounting seat 14, a spring support tube 15 and a cutter 16. The spring support tube 15 is installed on the top of the cutter mounting seat 14. The two end portions of the cutter 16 are connected to the cutter mounting seat 14 through the spring support tube 15. A rectangular incision corresponding to the cutter 16 is opened on the edge surface of the frame plate 4.
[0020] A magnetic block is built into the upper edge of the frame plate 4, and an eraser 17 is adsorbed on the surface of the frame plate 4. The eraser 17 contains a magnet. The eraser 17 is adsorbed on the surface of the frame plate 4 through the interaction between the magnet and the magnetic block inside the frame plate 4. The eraser 17 is used to erase the wrong content after writing English words and sentences on the writing board 2 with a water writing pen.
[0021] The writing board 2 is tilted from the carrier board 3 by the annular hinge shaft 5 and passes through the rectangular slot of the frame board 4 .
[0022] Working principle:
[0023] There are multiple writing boards 2 in the device. Under normal conditions, multiple writing boards 2 are stacked from top to bottom, and the bottom carrier board 3 is used for support. When writing, the water writing pen 18 placed on the frame board 4 is manually picked up to write English composition or words on the writing board 2. The eraser 17 has a built-in magnet inside. The eraser 17 and the surface of the frame board 4 are adsorbed by the magnet and the magnetic block. When writing mistakes are made, the eraser 17 can be manually removed to wipe the writing board 2.
[0024] When writing English sentences on a single writing board 2, and the writing board 2 has no more space on the writing board surface, the film of the film roll 12 is manually pulled out from the inner rectangular notch of the frame plate 4, and the film is pulled out along the slide groove 11 toward the fixed column 1 until the area of the film in the rectangular notch can cover the surface of the writing board 2, and then the writing board 2 filled with English sentences is flipped to the right side so that the film covers the surface of the writing board 2. At this time, the writing board 2 presses the film, and the film in the rectangular notch is fixedly attached to the surface of the writing board 2 by the double-sided tape 13;
[0025] Then, the cutter 16 is manually pressed to cut the film pulled out from the rectangular cutout on the surface of the frame plate 4 near the film roll 12. Thus, the writing board 2 filled with English sentences is protected by the film pulled out from the film roll 12 after writing, so that the written content is preserved and the content on the writing board 2 is prevented from being damaged by external rain, dust, etc.
[0026] In the above-mentioned process of flipping a single writing board 2 to the right, the limit rod 8 of the sleeve structure is manually pulled out, so that the pulled-out part of the limit rod 8 abuts against the remaining writing boards 2, and the spring U-shaped tube 9 at the upper end of the connecting block 7 is pulled upward, so that the end of the spring U-shaped tube 9 is inserted into the insertion hole 10 on the outer surface of the fixed column 1, thereby achieving the function of fixing the limit rod 8. When the limit rod 8 is not needed, the spring U-shaped tube 9 is manually pulled upward and rotated, so that the top end of the spring U-shaped tube 9 is disengaged from the insertion hole 10 and reset downward under the action of the spring. The spring U-shaped tube 9 and the limit rod 8 are both fixed on the connecting block 7, and the connecting block 7 is rotatably connected to the fixed column 1 by a rotating ring 6, so that the connecting block 7 can be manually rotated, so that the limit rod 8 can be conveniently adjusted at an angle on the outside of the fixed column 1 through the rotating ring 6, so as to abut against different numbers of stacked writing boards 2, and the limit rod 8 abuts against the remaining writing boards 2 without writing content, without pressing the remaining writing boards 2 by hand, which is more convenient to use;
[0027] In this scheme, after writing the content on multiple writing boards 2, the above steps can be followed. The film on the film roll 12 is manually pulled out along the slide groove 11, covering it tightly on the writing surface of the writing board 2, and cut by the cutter 16. After being protected by the film, the writing board 2 passes through the frame plate 4 and rotates to the bottom surface of the carrier plate 3.
[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
