DETAILED DESCRIPTION

[0035] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0036] like Figures 1 to 4 As shown, the multifunctional sitting posture corrector comprises:

[0037] The main board 10 is buckled on the table top. The main board 10 is composed of a panel 11 and a vertical board 12 which are perpendicular to each other. The panel 11 covers the surface of the table top. The vertical board 12 is buckled on the edge of the table top. Both sides of the main board 10 can be plugged with extension boards 30.

[0038] The support base 20 is vertically installed on one side of the vertical plate 12. The support base 20 includes a rotating block 21 movably connected to the vertical plate 12 and two pull rods 22 embedded in the rotating block 21. Two support blocks 23 are arranged on the top of the two pull rods 22. The pull rods 22 can drive the two support blocks 23 to move up and down. The rotating block 21 can drive each pull rod 22 and the support block 23 to rotate to the bottom of the lower table board.

[0039] Most of the existing sitting posture correctors are clamped on the table top, but the connection between the clamping part and the table top is not suitable, and the supporting part is basically fixed. When not in use, the entire sitting posture corrector needs to be disassembled, which is inconvenient to use; some styles can rotate the supporting part to reduce space occupation, but the rotation angle is limited and cannot be completely stored; in addition, the rotatable sitting posture corrector can only achieve rapid rotation and cannot achieve arbitrary hovering according to actual use needs.

[0040] To this end, the utility model provides a multifunctional sitting posture corrector, which can be directly buckled on the table top through the setting of the main board 10, and is suitable for different types of table tops; at the same time, extension plates 30 can be arbitrarily installed on both sides of the main board 10 to further increase the use area of ​​the desktop; in addition, the matching setting between the rotating block 21 and the protrusion 13 and the vertical plate 12 realizes the function of rotating the entire support base 20 by 270°, and the support base 20 can realize any angle hovering within the range of 270°, which is easy to use and convenient to store and organize, and has a good use effect.

[0041] Specifically, the sitting posture corrector is composed of a main board 10 and a support base 20. When in use, the main board 10 is buckled on the table board, and the panel 11 can independently form a flat work surface. The user can directly study and work on the panel 11, which is suitable for different types of table boards. The vertical board 12 cooperates with the panel 11 to ensure that the main board 10 is tightly buckled with the table board, which is also conducive to the installation of the support base 20.

[0042] The provision of the extension plate 30 can increase the usable area of ​​the main board 10 and expand the learning and working space. The extension plate 30 can actually be installed on one side of the main board 10 or on both sides of the main board 10. The user can choose according to actual needs.

[0043] Among them, the main board 10 and the extension board 30 can be printed with learning-related formulas, principles, graphics, tables and other contents, which are convenient for users to search and have good use effect.

[0044] Here, the support base 20 is preferably installed on the side of the vertical plate 12 away from the table top. The support base 20 is movably connected to the vertical plate 12 through a rotating block 21. The rotating block 21 is provided with a pull rod 22 and a support block 23 to support the user's body.

[0045] When in use, the rotating block 21 is in a vertical position together with the vertical board 12, so that the supporting block 23 can be against the user to ensure a correct sitting posture; when not in use, the rotating block 21 is rotated with the pull rod 22 and the supporting block 23 to the bottom of the table top for storage, so as to avoid affecting other uses of the table top.

[0046] Preferably, the support block 23 is connected to the rotating block 21 through a pull rod 22, and the height position of the support block 23 is adjusted by moving the pull rod 22 up and down, so as to be suitable for users of different heights. The specific height range of the pull rod 22 can be selected according to actual needs and is not limited in this embodiment.

[0047] like Figure 1 , Figure 4 and Figure 5As shown, preferably, part of the vertical plate 12 protrudes outward to form a protrusion 13, and the middle part of the protrusion 13 is reversely concave inward to form a first groove 131. A second groove 121 corresponding to the first groove 131 is opened at the bottom of the vertical plate 12. The first groove 131 and the second groove 121 are interconnected and arranged perpendicular to each other. The above-mentioned rotating block 21 is embedded in the first groove 131 and the rotating block 21 can rotate from the first groove 131 to the second groove 121.

[0048] The setting of the protrusion 13 here facilitates the installation of the support seat 20. The rotating block 21 is actually embedded in the first groove 131 on the protrusion 13. A second groove 121 is further set at the bottom of the vertical plate 12. The two grooves are interconnected to facilitate the rotating block 21 to reciprocate between the first groove 131 and the second groove 121. The setting of the two grooves facilitates the accommodation of the rotating block 21 at both ends of the rotation trajectory, thereby ensuring the stability of the rotating block 21 (the entire support seat 20).

[0049] The two grooves are arranged perpendicular to each other, so that the rotating block 21 rotates 270° when rotating from the first groove 131 to the second groove 121, thereby achieving the purpose of large-angle rotation.

[0050] In this embodiment, the second groove 121 is preferably actually a notch at the bottom of the vertical plate 12 , and the notch is connected to the first groove 131 to form the second groove 121 , so as to accommodate the rotating block 21 and facilitate production.

[0051] Furthermore, two ridges 132 are symmetrically arranged on the two side walls of the first groove 131. Preferably, the ridges 132 are arranged in the first groove 131, and when the rotating block 21 rotates into the first groove 131, it engages with the corresponding ridges 132 to ensure the stability of the rotating block 21, further ensure the stability of the support seat 20, and also facilitate the user to confirm whether the rotating block 21 (support seat 20) has been rotated into place.

[0052] like Figure 1 , Figure 5 and Figure 7 As shown, preferably, two sleeves 14 are symmetrically provided at the bottom of the protrusion 13 , and the two sleeves 14 are arranged on both sides of the rotating block 21 . One end of the sleeve 14 is threadedly connected to the protrusion 13 , and the other end is movably connected to the rotating block 21 through the damping shaft 15 .

[0053] In this embodiment, the rotating block 21 is preferably connected to the sleeve 14 on the protrusion 13 through the damping shaft 15. The end of the sleeve 14 has a knob. The knob is turned to thread the sleeve 14 with the bottom of the vertical plate 12. One end of the damping shaft 15 is embedded in the rotating block 21, and the other end is embedded in the sleeve 14. When the rotating block 21 rotates, it can drive the damping shaft 15 to rotate around itself, thereby realizing the rotation of the rotating block 21 around the protrusion 13.

[0054] After long-term use, if the sleeve 14, the damping shaft 15 and other parts are damaged, the sleeve 14 can be removed from the protrusion 13, and the knob can be rotated in the opposite direction to pull out the sleeve 14, and the sleeve 14 or the damping shaft 15 and other parts can be replaced, which is easy to operate.

[0055] The damping shaft 15 provided here can make the rotating block 21 hover at any position, which is more suitable for various occasions of actual use. The rotation angle can be selected according to the use requirements, and the practicability is good.

[0056] Furthermore, a through hole 212 corresponding to the damping shaft 15 is formed through the bottom of the rotating block 21 , and the outer peripheral portion surrounding the through hole 212 is hollowed out.

[0057] Preferably, a through hole 212 is provided at the bottom of the rotating block 21, which, on the one hand, facilitates the installation of the damping shaft 15, and on the other hand, can also reduce the weight of the rotating block 21 and facilitate rotation; wherein the outer peripheral portion of the through hole 212 is hollowed out, and it can also be considered that reinforcing ribs are provided around the through hole 212, which can further reduce the weight of the rotating block 21, and at the same time also improves the structural strength of the rotating block 21, enhances the torque, and is beneficial to increasing the service life of the rotating block 21.

[0058] like Figures 7 to 9 As shown, preferably, an arc plate 25 is provided on the top of the pull rod 22, the two support blocks 23 are installed on the surface of the arc plate 25 and the support blocks 23 can move left and right along the arc plate 25, and the back of the arc plate 25 is fixedly connected to the two pull rods 22 through a cover cap 26.

[0059] In this embodiment, an arc plate 25 is preferably provided on the top of the pull rod 22 to install the support block 23, wherein two pull rods 22 are provided, which is beneficial to improving the overall stability of the support base 20. The structure of the pull rod 22 can be in the form of a suitcase pull rod 22, and in actual production, a suitable pull rod 22 can also be selected according to needs.

[0060] The arrangement of the cover cap 26 here facilitates the connection between the arc plate 25 and the pull rod 22. The arc plate 25 is bent toward the user, and the two support blocks 23 are against the user for support during use.

[0061] Furthermore, a plurality of first reinforcing ribs 211 are fixedly disposed in the rotating block 21 around the two pull rods 22 , and a plurality of second reinforcing ribs 261 are fixedly disposed in the cap 26 around the two pull rods 22 .

[0062] The provision of the first reinforcing rib 211 and the second reinforcing rib 261 can ensure that the pull rod 22 is firmly connected to the rotating block 21 and the cover cap 26 , while also reducing the weight of the rotating block 21 and the cover cap 26 , which is beneficial to the smooth rotation of the entire support seat 20 .

[0063] The pull rod 22 is connected to the rotating block 21 and the cover cap 26 by screws. Such a structure makes it easy to install and disassemble the support seat 20, and further facilitates the replacement of parts.

[0065] The clamping block 241 on the bottom plate 231 cooperates with the slide groove 251 on the arc plate 25 to facilitate the support block 23 to move left and right along the arc plate 25. The distance between the two support blocks 23 can be adjusted according to the different sizes of the body frames of different users, so as to adapt to the body structures of different users.

[0066] The setting of the pad 232 is convenient for improving the softness of the support block 23 and improving the comfort of the pad 23 when it is used against the user. The pad 232 can be set with an integrated sponge structure or by filling the pad 232 with sponge.

[0067] like Figure 8 As shown, in this embodiment, preferably, an annular groove 233 is formed around the bottom plate 231, and the edge of the cushion block 232 is clamped inside the annular groove 233. The cushion block 232 is filled with elastic materials such as sponge, which is convenient for installation and disassembly, and the user can fill the sponge appropriately according to their own use. The area of ​​the cushion block 232 is relatively large, which increases the contact area between the cushion block 232 and the user, further improving the comfort.

[0068] Furthermore, circular protrusions 242 are respectively provided on the upper and lower sides of the clamping block 241 , and two rows of circular grooves 252 corresponding to the two circular protrusions 242 are opened on both sides of the sliding groove 251 .

[0069] When the clamping block 241 moves along the slide groove 251, the circular protrusions 242 on the upper and lower sides of the clamping block 241 move accordingly and are embedded in the corresponding circular grooves 252 on the slide groove 251 for clamping, thereby realizing the gear adjustment of the relative position between the support block 23 and the arc plate 25. The specific number of circular protrusions 242 and circular grooves 252 can be set according to the length of the arc plate 25 and the specific adjustment conditions during actual use, and is not limited here.
