[0042] Embodiment:

[0043] Figure 1 is a schematic structural view of a multifunctional sitting posture corrector provided by an embodiment of the present utility model, Figure 2 is a side view of a multifunctional sitting posture corrector provided by an embodiment of the present utility model, combined with Figure 1 and Figure 2 as shown, the multifunctional sitting posture corrector includes a base 1, a correction member 2 and a reading board 3.

[0044] On the side edge of the base 1, there is a protruding mounting block 11. On the base 1, there are a first plane 12 and a second plane 13. The first plane 12 is used to be placed on the desk, and the second plane 13 is used to support the book when writing. The second plane 13 forms an angle with the first plane 12.

[0045] The correction member 2 is used to form a limit to correct the sitting posture. The correction member 2 is inserted on the mounting block 11. The reading board 3 is used to support the book when reading. The reading board 3 is detachably arranged on the base 1, and the second plane 13 is located between the reading board 3 and the correction member 2. The bottom of the correction member 2, the second plane 13 and the bottom of the reading board 3 are successively raised, and the top of the reading board 3 is higher than the top of the correction member 2.

[0046] For a multifunctional sitting posture corrector provided by an embodiment of the present utility model, when in use, the first plane 12 of the base 1 is placed on the desktop of the desk, and the mounting block 11 is made to protrude from the desk, so that the correction member 2 can also protrude from the desk, avoiding the risk of the student's body touching the desk too closely while correcting the sitting posture of the body. In addition, the second plane 13 of the base 1 serves as a writing board to support the book when writing, and the angle formed by the second plane 13 and the first plane 12 makes the second plane 13 relatively inclined. The reading board 3 can support the book when reading, so as to finally cooperate with the reading and writing scenarios while correcting the sitting posture, enriching the functions of the sitting posture corrector.

[0047] Further, the second plane 13 is located between the reading board 3 and the correction member 2, such that the correction member 2, the second plane 13, and the reading board 3 form a three-dimensional integrated spatial structure (overall regarded as a U-shaped structure), which cooperate with each other spatially but are functionally independent of each other, avoiding mutual interference. Additionally, since the second plane 13 is inclined, and the bottom of the correction member 2, the second plane 13, and the bottom of the reading board 3 are successively elevated, and the top of the reading board 3 is higher than the top of the correction member 2 (i.e., in the direction perpendicular to the first plane 12), it is convenient for writing while correcting the sitting posture, and the reading line of sight is good.

[0048] That is to say, a multifunctional sitting posture corrector provided by an embodiment of the present invention not only realizes the cooperation with the reading and writing scenarios while correcting the sitting posture, enriches the functions of the sitting posture corrector, but also can be independent of each other spatially, avoiding mutual interference, and improving the usage effect of students.

[0049] It is easy to understand that for this multifunctional sitting posture corrector, the bottom of the correction member 2, the second plane 13, and the bottom of the reading board 3 are successively elevated in spatial arrangement, and a good reading angle can be guaranteed while writing. Additionally, the position of the reading board 3 is relatively high compared to the correction member 2, and the reading board 3 can be elevated to a certain extent, facilitating reading at eye level and avoiding fatigue caused by the downward reading line of sight due to the excessive height of the correction member 2.

[0050] Exemplarily, in the horizontal direction, the first included angle α3 formed by the connection line from the top of the correction member 2 to the top of the reading board 3 and the horizontal direction is 15 - 30°, and the second included angle α4 formed by the connection line from the top of the correction member 2 to the bottom of the reading board 3 and the horizontal direction is 10 - 20°.

[0051] In addition, the range of the included angle α1 formed by the first plane 12 and the second plane 13 is 10 - 20°, which is convenient for writing while correcting the sitting posture, and the writing line of sight is good. Preferably, the included angle α1 between the first plane 12 and the second plane 13 is 12°.

[0052] Exemplarily, the base 1 is a triangular structure, and both the bottom surface (i.e., the first plane 12) and the side surface of the base 1 have notches, which play a role in weight reduction.

[0053] In this embodiment, one side of the mounting block 11 has a limiting surface 111, and the limiting surface 111 extends downward and is perpendicularly connected to the first plane 12.

[0054] In the above embodiment, when installing this multifunctional sitting posture corrector, the first plane 12 is attached to the desktop, and the limiting surface 111 is attached to the table edge, realizing reliable limiting of the multifunctional sitting posture corrector and preventing the multifunctional sitting posture corrector from sliding inward along the desktop during use.

[0055] Exemplarily, anti-slip patterns are provided on both the first plane 12 and the second plane 13, thereby increasing the friction when they come into contact and reducing the risk of slipping.

[0056] Figure 3 It is a schematic structural view of the base provided by an embodiment of the present utility model. As Figure 3 shown, the base 1 has a positioning groove 14, and the positioning groove 14 is located between the second plane 13 and the reading board 3. The positioning groove 14 is used for inserting a tablet computer. The tablet computer can be conveniently inserted into the positioning groove 14, facilitating students to use the tablet computer.

[0057] Furthermore, the bottom of the reading board 3 has a protrusion 31. One side surface of the protrusion 31 is parallel to one side surface of the positioning groove 14. The protrusion 31 can further support the tablet computer, making the arrangement of the tablet computer more stable.

[0058] Figure 4 It is a schematic structural view of the reading board provided by an embodiment of the present utility model. Combining Figure 3 and Figure 4 shown, the bottom of the reading board 3 has a plurality of mounting platforms 32 arranged at intervals. The base 1 has a plurality of slots 15 arranged at intervals, and one side of the slot 15 extends out of the side of the base 1. Each mounting platform 32 is slidably inserted into the corresponding slot 15.

[0059] In the above embodiment, the convenient insertion of the reading board 3 can be achieved through the cooperation of the slot 15 and the mounting platform 32, facilitating carrying after disassembly.

[0060] Exemplarily, the number of the mounting platforms 32 can be 2.

[0061] Furthermore, one end of each mounting platform 32 has a convex block 321. The convex block 321 is slidably inserted into the base 1. Through the anti-abutment cooperation of the base 1 on the convex block 321, the mounting platform 32 can be prevented from disengaging from the slot 15 in the vertical direction. That is to say, the vertical limit can be achieved through the convex block 321, avoiding accidental dropping during use. In addition, under the limit of the convex block 321, the reading board 3 can only be inserted from the side (horizontal direction).

[0062] Exemplarily, the convex block 321 is inserted into the notch at the bottom of the base 1.

[0063] It should be noted that the reading board 3 can also be detachably connected by bolts or buckles, and the present utility model does not limit this.

[0064] Exemplarily, the included angle α2 between the reading board 3 and the second plane 13 is 120° - 150°, so that the reading surface of the reading board 3 can be inclined outward, facilitating the placement and reading of books.

[0065] In this embodiment, there are two skirt edges 16 on the side of the base 1. The two skirt edges 16 are located between the correction member 2 and the reading board 3 and on both sides of the second plane 13. The skirt edges 16 are used to support the student's elbows to avoid the elbows hanging in the air and enhance the comfort during writing.

[0066] Exemplarily, the skirt edge 16 is arranged coplanarly with the second plane 13.

[0067] In one implementation manner of the present utility model, there are two book clips 33 arranged at intervals on the side of the reading board 3 facing the correction member 2.

[0068] In the above implementation manner, the book clips 33 are used to clip books, especially when the books are opened.

[0069] Further, the bottom of the reading board 3 has a mounting plate 34. The mounting plate 34 is detachably arranged on the base 1. There are two accommodating grooves 341 arranged at intervals on the mounting plate 34. One end of the book clip 33 is hinged in the corresponding accommodating groove 341, and the other end of the book clip 33 is used to rotate out of the accommodating groove 341 and then clip the book with the reading board 3.

[0070] It is easy to understand that when no book is placed on the reading board 3, the book clip 33 can be rotated and placed in the accommodating groove 341 at this time for easy hiding. And when it is necessary to clip a book on the reading board 3, rotate the book clip 33 so that the clamping end of the book clip 33 rotates above the reading board 3 to cooperate with the reading board 3 to realize the clamping of the book.

[0071] Exemplarily, the mounting table 32 is located on the bottom surface of the mounting plate 34. The protrusion 31 is located on the mounting plate 34.

[0072] Figure 5 It is a schematic structural diagram of the correction member provided by the embodiment of the present utility model. As Figure 5 shown, the correction member 2 includes a support portion 21 and a limiting portion 22. The bottom end of the support portion 21 is inserted into the mounting block 11, and the limiting portion 22 is located at the top end of the support portion 21.

[0073] In the above implementation manner, the support portion 21 plays a role in supporting and elevating the limiting portion 22, and the limiting portion 22 can support the student's lower jaw or prevent the student's shoulders from moving down, thereby forcing the student to adjust to the correct sitting posture.

[0074] In this embodiment, the support portion 21 is a rod with adjustable length. By adjusting the support portion 21 in the height direction, the sitting height is limited, and the applicable range is increased.

[0075] Specifically, the support portion 21 includes a plurality of sub-rods arranged coaxially in sequence. The top end of the uppermost sub-rod is connected to the limiting portion 22, and the lowermost sub-rod is rotatably inserted into the mounting block 11 through a rotating shaft, so as to rotate the correction member 2 below the desktop in the non-use state, avoiding interference in the non-use state. One end of the adjacent sub-rods is slidably inserted into one end of the adjacent sub-rods to achieve telescopic adjustment.

[0076] Exemplarily, the number of sub-rods can be 3 - 5.

[0077] In addition, on the side of the limiting portion 22 facing away from the reading board 3, there are two resilient bread pads 23 arranged at intervals. The resilient bread pads 23 play a buffering role to avoid hard contact between the student's body and the limiting portion 22.

[0078] Exemplarily, this multifunctional sitting posture corrector can be a polyethylene structural member, with high structural strength and long service life.

[0079] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
