DETAILED DESCRIPTION

[0024] The technical solution in one embodiment of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-6 :

[0026] A conveniently fixed sitting posture corrector, comprising a correction member assembly, a support body, a lower movable splint assembly, an upper movable splint 5, a lower button assembly, and a fine-tuning knob assembly;

[0027] The support body is an L-shaped shell structure, including a vertical cylinder 31 and a horizontal column base 32. The column base 32 is generally cylindrical and has a downward opening. The cylinder 31 and the column base 32 are connected. A button hole 321 is provided on the lower rear side of the column base 32, and a fine-tuning knob mounting hole 322 is provided on the top surface of the column base 32.

[0028] The correction abutment assembly includes a correction abutment 11, which is sleeved with the upper portion of the cylinder 31 and can be lifted and lowered relative to the upper portion of the cylinder 31;

[0029] The lower movable splint assembly includes a lower lifting column 41 and a lower movable splint 42 integrally connected to the bottom of the lower lifting column 41. The front side of the lower lifting column 41 is provided with a strip-shaped lower lifting tooth 411;

[0030] The lower button assembly includes a button column 61, a moving block 62, and a lower spring 63. The button column 61 is located on the rear side of the moving block 62 and is sleeved in the button hole 321. The moving block 62 has a first through-hole 621 for the lower lifting column 41 to pass through. The front side of the inner wall of the first through-hole 621 is provided with a strip-shaped lower locking tooth 622 that cooperates with the strip-shaped lower lifting tooth 411. The moving block 62 is moved within the column seat 32 by the lower spring 63.

[0031] The upper movable splint 5 is provided with a second through-hole 51 for the lower lifting column 41 to pass through, and a nut structure 52 is provided on the upper movable splint 5. The fine-tuning knob assembly is mounted on the column base 32 through the fine-tuning knob mounting hole 322 and is threadedly connected to the nut structure 52. The button assembly structure of this solution is simple in design and easy to operate. During installation, a single press of the button column 61 is required to push the movable block 62, disengaging the locking rack 622 from the bar-shaped lower lifting tooth 411. After adjusting the height of the lower movable splint, the button column is released, and the bar-shaped lower lifting tooth and the bar-shaped lower locking tooth are plugged and locked. Since the bar-shaped lower lifting tooth of the lifting column and the bar-shaped lower locking tooth of the movable block are both configured as bar-shaped structures, the bar-shaped lower locking tooth of the movable block has a larger locking surface on the bar-shaped lower lifting tooth of the lifting column, making the locking more secure, thereby making the clamping of the table edge more secure.

[0032] In this embodiment, an upper locking block 324 is preferably provided on the inner wall of the cylinder 31, and an elastic locking tongue 412 is provided on the upper portion of the lower lifting column 41. When installing the lower movable clamp assembly, the lower lifting column 41 is inserted into the cylinder 31 from the bottom of the support body. During the insertion process, the elastic locking tongue 412 passes over the upper locking block 324, thereby preventing the lower lifting column 41 from being separated from the support body.

[0033] In this embodiment, as a preference, limiting holes 623 are provided on both sides of the first through hole 621 of the moving block 62, and the limiting holes 623 are in the shape of an elongated strip. The inner wall of the top of the column seat 32 is connected with a limiting column 325 which is sleeved on the limiting hole 623. The limiting column 325 is provided with a limiting screw hole. The outer diameter of the limiting hole 623 is larger than the outer diameter of the limiting column 325. The moving block 62 is moved inside the column seat 32 through the screws, the limiting column 325 and the limiting hole 623.

[0034] In this embodiment, preferably, a lower spring mounting groove 624 is provided on the rear side of the moving block 62, a lower spring mounting plate 326 is provided in front of the moving block 62, and the lower spring 63 is provided between the lower spring mounting groove 624 and the lower spring mounting plate 326 to facilitate the installation of the lower spring 63.

[0035] In this embodiment, the fine-tuning rotation assembly preferably includes a fine-tuning knob 71 and a stud 72. The stud 72 is connected to the knob 71 by a screw. A raised nut structure 52 is provided on the upper surface of the upper movable clamping plate 5. The stud 72 and the nut structure 52 cooperate to adjust the raising and lowering of the upper movable clamping plate 5, thereby securing the upper movable clamping plate 5 and the lower movable clamping plate 42 to the edge of the table.

[0036] In this embodiment, as a preference, the correction resist assembly further includes an upper lifting column 12 integrally connected to the correction resist 11, and an upper button assembly is also attached to the cylinder 31, the upper button assembly including a button block 21, an upper spring 22, a button slot frame 23, and a rotating shaft 24. The button slot frame 23 is attached to the front side of the cylinder 31, and an upper jack 323 is provided on the side of the cylinder 31 located above the interior of the button slot frame 23; a first shaft hole 231 is provided in the middle of the left and right opposite sides of the button slot frame 23, and the upper back of the button block 21 is provided. The upper lifting column 12 is provided with a toothed insert 211, a second axial hole 212 in the middle, and an upper spring mounting slot 213 in the lower portion. A strip-shaped lifting tooth 121 is provided on the side of the upper lifting column 12 facing the upper socket 323, which mates with the toothed insert 211. The button block 21 and the button slot frame 23 are rotatably connected via a rotating shaft 24, a first axial hole 231, and a second axial hole 212. The upper spring 22 is mounted within the upper spring mounting slot 213 and the lower portion of the button slot frame 23. The toothed insert 211 can lock the upper lifting column 12 through the upper socket 323. This solution allows the upper button assembly to be used to raise and lower the corrective abutment assembly, making operation very convenient.

[0037] A lower gasket 82 is provided at the bottom of the upper movable splint, and an upper gasket 81 is provided at the top of the lower movable splint to avoid damage to the desktop.

[0038] When in use, first press the button column 61 to disengage the locking rack 622 from the bar-shaped lower lifting tooth 411, then adjust the lower movable splint 42 to form a clamping gap between the upper movable splint 5 and the lower movable splint 42 to clamp the edge of the table, then release the button column 6 to plug the locking rack 622 into the bar-shaped lower lifting tooth 411, locking the lower lifting column 41, finally, rotate the fine-tuning knob 71 to lower the upper movable splint 5 to further clamp the edge of the table; when in use, just press the button column.

[0039] Next, the height of the upper lifting column 12 is adjusted by adjusting the upper button assembly 2. The operation method is: first press the lower part of the upper button block 21, and the upper part of the upper button block 21 tilts backward to disengage the inserting teeth 211 of the upper button block 21 from the lifting teeth 121 of the upper lifting column 12. Then, adjust the correction member 11 to a suitable height, release the upper button block 21, and make the inserting teeth 211 of the upper button block 21 engage with the lifting teeth 121 of the lower upper lifting column 12, thereby completing the adjustment and fixation of the correction member 11.
