[0029] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and the specific embodiments.

[0030] Please refer to Figures 1 to 6 , the embodiment of the present application provides a sitting posture corrector for students, including a main body 1 and a fixing component 2. A U-shaped notch 11 is provided at the top of the main body 1, and a connecting hole 12 is provided at the bottom of the main body 1. The main body 1 is rotatably connected to the fixing component 2 through the connecting hole 12; two groups of first rotating rods 13 are symmetrically arranged in the U-shaped notch 11, and a support rod 3 is rotatably connected to the two groups of first rotating rods 13. A semi-circular surface is provided at the bottom end of the support rod 3, and a plurality of first protrusions 31 and first grooves 32 are arranged at intervals on the semi-circular surface; a first sliding rod 14 is further provided in the U-shaped notch 11. The first sliding rod 14 is located below the first rotating rod 13, and a slider 4 is slidably connected to the first sliding rod 14. A convex block 41 is provided at the top end of the slider 4, and an arc surface is provided at the top of the convex block 41. A plurality of second protrusions 42 and second grooves 43 are arranged at intervals on the arc surface. The second protrusions 42 are adapted to the first grooves 32, and the second grooves 43 are adapted to the first protrusions 31; sliding grooves 15 are provided on both sides of the main body 1. The sliding grooves 15 are located below the U-shaped notch 11, and a handle 16 is provided on one side of the slider 4. The handle 16 is slidably connected to the sliding groove 15.

[0031] Working principle and effect: This device is installed on the table through the fixing component 2 and is located directly in front of the user. The main body 1 is rotatably connected to the fixing component 2, so that the main body 1 can rotate, thereby driving the two groups of support rods 3 on the main body 1 to rotate, enabling the support rods 3 to replace between two states of being perpendicular to the tabletop or parallel to the tabletop; as Figure 1 or Figure 2As shown, the two groups of support rods 3 on the main body 1 can be rotated and opened in opposite directions. The user can adjust the opening angle of the support rods 3 according to their own needs, so that the support rods 3 can avoid the chest position and press against the user's body, thereby helping the child to maintain an upright sitting posture. Specifically, when the user does not need to use the sitting posture corrector, the two groups of support rods 3 are rotated in a direction close to each other until the two groups of support rods 3 are parallel to each other and perpendicular to the desktop, then the rotation is stopped and fixed. Then, the main body 1 and the two groups of support rods 3 are rotated to a state parallel to the desktop through the rotation connection between the main body 1 and the fixing component 2. At this time, as shown in FIG. Figure 3 As shown, the two groups of support rods 3 and the main body 1 are in a state parallel to the desktop, which will not block the user's line of sight in front of them, effectively solving the problem of folding and unfolding the sitting posture corrector without disassembling it, making it convenient for users to use.

[0032] like Figures 5 to 6 As shown, the support rod 3 can rotate around the first rotating rod 13. Specifically, the handles 16 in the slide grooves 15 on both sides of the main body 1 are used to control the sliding of the slider 4. When the support rod 3 is in a fixed state (cannot rotate), the first protrusion 31 at the bottom of the support rod 3 is inserted into the second groove 43 at the top of the slider 4, and the second protrusion 42 at the top of the slider 4 is inserted into the first groove 32 at the bottom of the support rod 3. The support rod 3 is fixed by the snap connection between the first protrusion 31 and the second groove 43 and the snap connection between the second protrusion 42 and the first groove 32. When the support rod 3 needs to be rotated, pull the handles 16 on both sides of the main body 1. 6, so that the handle 16 slides along the slide groove 15 toward the user, thereby driving the slider 4 to slide along the first slide rod 14 toward the user, so that the second protrusion 42 disengages from the first groove 32, and the first protrusion 31 disengages from the second groove 43, and then the support rod 3 is rotated until it is rotated to the position required by the user, and then the handles 16 located on both sides of the main body 1 are pulled to make the handles 16 slide along the slide groove 15 away from the user, thereby resetting the slider 4, so that the second protrusion 42 is re-engaged with the first groove 32, and the first protrusion 31 is re-engaged with the second groove 43, and the support rod 3 is fixed again.

[0033] In one embodiment, Figure 1 As shown, the fixing assembly 2 includes a U-shaped clamping head, which includes an upper horizontal plate 21, a lower horizontal plate 22 and a vertical plate 23, and a clamping threaded column 24 is provided on the lower horizontal plate 22. The U-shaped opening of the U-shaped clamping head is aligned with the table board so that the table board is located between the upper horizontal plate 21 and the lower horizontal plate 22, and then the clamping threaded column 24 is rotated from the lower horizontal plate 22 toward the upper horizontal plate 21, so that the clamping threaded column 24 fixes the U-shaped clamping head on the table board.

[0034] In one embodiment, a mounting seat 5 is provided on the vertical plate 23. The mounting seat 5 includes a disc 51 and a square block 52. A second rotating rod 53 is provided on the disc 51, and the connecting hole 12 is rotatably connected to the second rotating rod 53. The connecting hole 12 is rotatably connected to the second rotating rod 53, so that the main body 1 is mounted on the mounting seat 5 and can rotate around the mounting seat 5.

[0035] In one embodiment, a convex-shaped groove 54 is provided on the square block 52. A reset spring (not shown in the figure) is provided in the convex-shaped groove 54. A push block 55 is provided on the reset spring. The push block 55 is slidably connected to the convex-shaped groove 54. A clamping block 56 is provided on the push block 55. A plurality of clamping grooves 121 are provided on one side of the connecting hole 12, and the clamping grooves 121 are located on the side close to the mounting seat 5. The clamping block 56 is adapted to the clamping grooves 121. When the device is in the retracted state (that is, both sets of support rods 3 and the main body 1 are in a state parallel to the tabletop), by pressing the push block 55 in the direction of the convex-shaped groove 54, the push block 55 slides along the convex-shaped groove 54, so that the clamping block 56 on the push block 55 disengages from the clamping groove 121 on one side of the connecting hole 12. At this time, the main body 1 and the mounting seat 5 are in an active connection, and the main body 1 can rotate around the mounting seat 5. When the main body 1 rotates to a state perpendicular to the tabletop, release the push block 55. Under the action of the reset spring, the push block 55 slides in the direction away from the convex-shaped groove 54, so that the clamping block 56 on the push block 55 is clamped into the clamping groove 121 on one side of the connecting hole 12, thereby fixing the main body 1 in a state perpendicular to the tabletop for the convenience of the user; conversely, the main body 1 in a state perpendicular to the tabletop can be rotated to a state parallel to the tabletop, so as to realize the retraction of the main body 1 and the two sets of support rods 3.

[0036] In one embodiment, as Figure 4 shown, a sheath 33 is sleeved on the support rod 3. The support rod 3 is used to abut against the user's body. A sheath 33 is sleeved on the support rod 3. The sheath 33 made of a soft material can be used to improve the user's comfort during use.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
