DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0032] like Figures 1 to 3 As shown, the flip-type sitting posture corrector comprises:

[0033] The clamping seat 10 is clamped on the edge of the table top. The clamping seat 10 has a vertical plate 11. The upper and lower ends of the vertical plate 11 are bent and extended to form an upper clamping plate 12 and a lower clamping plate 13. The table top is located between the upper clamping plate 12 and the lower clamping plate 13. Two bolts 14 are vertically penetrated on the lower clamping plate 13. Each bolt 14 is sleeved with a top cap 15 and the two top caps 15 are respectively against the bottom of the table top;

[0034] The support seat 20 is vertically installed on one side of the vertical plate 11. The support seat 20 includes a rotating block 21 movably connected to the vertical plate 11 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 support block 23 to rotate to the bottom of the lower clamping plate 13.

[0035] Most of the existing sitting posture correctors are fixedly installed and need to be disassembled when not in use, 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.

[0036] To this end, the utility model provides a flip-up sitting posture corrector, which realizes the function of rotating the entire support base 20 by 270° through the coordinated arrangement of the rotating block 21, the vertical plate 11 and the lower clamping plate 13, and the support base 20 can hover at any angle within the range of 270°, which is easy to use and convenient to store and organize, and has a good use effect.

[0037] Specifically, the utility model adopts a clamping table structure, which is composed of a clamping seat 10 and a supporting seat 20 that are installed in coordination. The clamping seat 10 is actually composed of an upper clamping plate 12, a vertical plate 11 and a lower clamping plate 13, which are arranged in a "[" shape. During actual installation, the clamping seat 10 is placed on the edge of the table board, the upper clamping plate 12 is against the surface of the table board, and the two bolts 14 are rotated so that the two top caps 15 are against the bottom of the table board to achieve clamping of the table board.

[0038] The two bolts 14 cooperate with the top cap 15 to facilitate the clamping base 10 to clamp the table top, while also ensuring the stability of the clamping base 10, further ensuring the stable installation of the support base 20, and facilitating use. The bolts 14 and the top cap 15 are detachable. If the bolts 14 and the top cap 15 are damaged after long-term use, they can be directly disassembled and replaced.

[0039] Preferably, a first gasket 121 is provided at the bottom of the upper clamping plate 12, and each top cap 15 is covered with a second gasket 151. The provision of the first gasket 121 and the second gasket 151 can protect the table top and reduce damage to the table top during the clamping process.

[0040] Here, the support base 20 is preferably installed on the side of the vertical board 11 away from the table top. The support base 20 is rotatably connected to the vertical board 11 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.

[0041] When in use, the rotating block 21 is in a vertical state together with the vertical board 11, 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 rotates with the pull rod 22 and the supporting block 23 to the bottom of the lower clamping plate 13 for storage, so as to avoid affecting other uses of the table top.

[0042] 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.

[0043] like Figures 4 to 6 As shown, preferably, the middle portion of the vertical plate 11 is concave inward toward the two clamping plates to form a first groove 111, and the middle portion of the lower clamping plate 13 is concave upward to form a second groove 131. The first groove 111 and the second groove 131 are perpendicular to each other and interconnected, and the above-mentioned rotating block 21 can rotate from the first groove 111 to the second groove 131.

[0044] In this embodiment, a first groove 111 is preferably provided on the vertical plate 11, and a second groove 131 is provided on the lower clamping plate 13. The two grooves are interconnected to facilitate the rotating block 21 to be able to reciprocate between the first groove 111 and the second groove 131. The setting of the two grooves facilitates accommodating the rotating block 21 at both ends of the rotating trajectory, thereby ensuring the stability of the rotating block 21 (the entire support seat 20).

[0045] The two grooves are arranged perpendicular to each other. When the rotating block 21 rotates from the first groove 111 to the second groove 131, it rotates 270 degrees, thereby achieving the purpose of large-angle rotation.

[0046] Furthermore, two first ridges 112 are symmetrically arranged on the two side walls of the first groove 111, and two second ridges 132 are symmetrically arranged on the two side walls of the second groove 131. Here, it is preferred to arrange ridges in the corresponding grooves, and when the rotating block 21 rotates into the corresponding groove, it engages with the corresponding ridges, further ensuring the stability of the rotating block 21, and also facilitating the user to confirm whether the rotating block 21 (support seat 20) has been rotated into place.

[0047] Preferably, two sleeves 115 are symmetrically provided at the bottom of the vertical plate 11 , and the two sleeves 115 are arranged on both sides of the rotating block 21 . One end of the sleeve 115 is threadedly connected to the vertical plate 11 , and the other end is movably connected to the rotating block 21 through a damping shaft 116 .

[0048] In this embodiment, the rotating block 21 is preferably connected to the sleeve 115 on the vertical plate 11 through the damping shaft 116. The end of the sleeve 115 has a knob. The knob is turned to thread the sleeve 115 with the bottom of the vertical plate 11. One end of the damping shaft 116 is embedded in the rotating block 21, and the other end is embedded in the sleeve 115. When the rotating block 21 rotates, it can drive the damping shaft 116 to rotate around itself, thereby realizing the rotation of the rotating block 21 around the vertical plate 11.

[0049] After long-term use, if the sleeve 115, the damping shaft 116 and other parts are damaged, the sleeve 115 can be removed from the vertical plate 11, and the knob can be rotated in the opposite direction to pull out the sleeve 115, and the sleeve 115 or the damping shaft 116 and other parts can be replaced, which is easy to operate.

[0050] The damping shaft 116 is provided here to enable the rotating block 21 to 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.

[0051] Furthermore, a through hole 212 corresponding to the damping shaft 116 is formed through the bottom of the rotating block 21 , and the outer peripheral portion surrounding the through hole 212 is hollowed out.

[0052] 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 116, 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.

[0053] like Figures 6 to 8 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.

[0054] 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.

[0055] 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.

[0056] 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 .

[0057] 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 .

[0058] 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.

[0059] like Figure 8 and Fig. 9 As shown, preferably, the support block 23 includes a bottom plate 231 and a cushion block 232 covering the surface of the bottom plate 231 , a clamping block 241 is arranged at the back of the bottom plate 231 , and two slide grooves 251 corresponding to the two clamping blocks 241 are opened on the arc plate 25 .

[0060] 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.

[0061] 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.

[0062] like Figure 7 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.

[0063] 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 .

[0064] 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.

[0065] It is worth mentioning that in this embodiment, the back of the bottom plate 231 is preferably fixedly connected with an auxiliary block 24, and the above-mentioned clamping block 241 and circular protrusion 242 are both located on the corresponding auxiliary block 24. The provision of the auxiliary block 24 can avoid direct contact between the bottom plate 231 and the arc plate 25, reduce friction, facilitate adjustment, and avoid wear between the support block 23 and the arc plate 25.

[0066] like Figure 4 and Figure 5 As shown, further, a plurality of buckles 114 are provided on both sides of the vertical plate 11 , and a plurality of third reinforcing ribs 113 are fixedly provided inside the vertical plate 11 .
