[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0033] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0034] This embodiment provides a posture corrector, referring to... Figure 1 The system includes a tabletop 1, a reading rack 2, and a chest rest. The chest rest and reading rack 2 are located at the front and back ends of the tabletop 1, respectively, allowing users to maintain a healthy reading distance and writing posture, thus achieving the effect of posture correction. The user's chest rests against the chest rest.

[0035] Specifically, the tabletop 1 can adopt a square, round or other arbitrary shape planar structure, allowing users to place items, or their hands and arms, on the tabletop 1.

[0036] Furthermore, the tabletop 1 is tilted upwards at a set angle from the front end to the rear end (towards the user), so that the front end of the tabletop 1 is in a low position and the rear end is in a high position. The appropriate tilt of the tabletop 1 ensures that the items on it are not easy to slip off, while raising the height of the items on the tabletop 1, thereby reducing the angle at which the user looks down when viewing items such as books on the tabletop 1, and has a better anti-myopia effect.

[0037] Preferably, the tilt angle of the tabletop 1 is 15°.

[0038] like Figure 1 , Figure 3 , Figure 9-10 As shown, the chest rest is located at the front end of the tabletop 1. The chest rest includes a head 31, a telescopic rod 32, and a connecting part 33. The head 31 and the connecting part 33 are respectively located at both ends of the telescopic rod 32. The head 31 is used to provide support for the user to lean against the tabletop 1, and the connecting part 33 is used to form a rotatable connection with the front end of the tabletop 1.

[0039] Reference Figure 4The front end of the tabletop 1 is provided with a mounting groove 12 that mates with the connecting part 33. The connecting part 33 is provided with a rotating shaft 331. The two ends of the rotating shaft 331 are respectively inserted into the inner side of the left and right side walls of the mounting groove 12. The rotating shaft 331 enables the connecting part 33 to rotate the entire chest rest relative to the tabletop 1. The tabletop at the mounting groove 12 includes an upper part and a lower part. The upper part and the lower part are engaged to form a mounting hole for the rotating shaft 331 to pass through. Preferably, the axis of the rotating shaft 331 is parallel to the left and right direction of the tabletop 1, so that the chest rest can rotate in the up and down direction relative to the tabletop 1.

[0040] Preferably, the mounting groove 12 is configured to form an opening facing forward. When the chest rest rotates around the pivot 331, when the chest rest rotates to the upward and downward positions, the telescopic rod 32 will abut against the rear wall of the mounting groove 12 to prevent the chest rest from rotating further. Thus, the range of rotation angle of the chest rest is 180°.

[0041] Reference Figure 5 As shown, a support ring 334 is provided inside the mounting groove 12 in the tabletop 1. The support ring 334 is fixedly connected to the tabletop. The support ring 334 is located on the outer periphery of the rotating shaft 331 to increase the stability of the rotating shaft when it rotates.

[0042] Furthermore, one or both sides of the shaft end of the connecting part 33 are provided with a toothed groove 332. The toothed groove 332 is distributed in a circumferential array on the outer periphery of the rotating shaft 331. Correspondingly, the mounting groove 12 is provided with a retaining tooth 333 on one or both sides of the side wall opposite to the shaft end of the connecting part 33. At any angle of the chest rest, the retaining tooth 333 engages with the toothed groove 332, thereby forming a certain damping effect on the rotation of the chest rest, so that the chest rest can stop at any angle position within the 180° rotation range. Its damping stopping effect provides users with more diverse comfort angle adjustment, allowing users to adjust the angle of the chest rest to achieve a more suitable sitting posture. Moreover, the retaining tooth 333 and the toothed groove 332 will produce clear tactile feedback during relative movement, effectively improving the user's operating experience. In addition, it can also effectively prevent the chest rest from accidentally flipping down quickly when the user temporarily removes it during use, causing fright or bumps.

[0043] Preferably, the tooth groove 332 is set as a semi-circular shape, covering the outer circumference of the rotating shaft 331 by 180°.

[0044] Reference Figure 2 and Figure 3 The bottom rear end of the tabletop 1 is provided with a support leg 11 that supports downwards to the placement surface. The bottom front end of the tabletop 1 can directly contact the placement surface, and the bottom rear end of the tabletop 1 contacts the placement surface through the support leg 11, thereby maintaining the tilted posture of the tabletop 1.

[0045] Due to the inclined design of the tabletop 1, a wedge-shaped space is formed between the bottom of the tabletop 1 and the horizontal plane. Furthermore, a drawer 4 is installed in the wedge-shaped space at the bottom of the tabletop 1 to make reasonable use of the space at the bottom of the tabletop 1.

[0046] Drawer 4 is mounted to the bottom of tabletop 1 via a bracket assembly, see reference. Figure 9 and Figure 10 The bracket assembly includes a slide rail 42 and a fixing frame 41. The fixing frame 41 has a U-shaped structure and an opening. It is fixedly installed on the bottom of the tabletop 1 by screws. The opening of the fixing frame 41 faces the left or right end in the direction perpendicular to the front and back of the tabletop 1, so that the fixing frame 41 forms an opening at the left or right end of the tabletop 1. The drawer 4 is set inside the fixing frame 41, so that it can be moved and pulled out relative to the left and right lateral sides of the tabletop 1.

[0047] The slide rail 42 is installed in the fixed frame 41 along the pull-out direction of the drawer 4. Specifically, slide rail 42 is provided on both opposite sides of the fixed frame 41. The length direction of the slide rail 42 is parallel to the pull-out direction of the drawer 4. The slide rail 42 is snapped and fixed to the fixed frame 41. The drawer 4 is provided with a sliding piece 44 and a roller 43 on one or both sides perpendicular to the pull-out direction. After the slide rail 42 is installed with the fixed frame 41, it forms a limiting groove for the sliding piece 44 to be inserted and move along the pull-out direction, and a roller groove for placing the roller 43 and making the roller 43 roll along the pull-out direction. The limiting groove and the roller groove provide vertical support and limiting for the drawer 4, and make the pull-out movement of the drawer 4 smoother.

[0048] A blocking part 421 is also provided on the end of the slide rail 42 near the drawer pull handle. The blocking part 421 is located at the end of the roller groove. When the drawer 4 is about to be completely pulled out from the fixing frame 41, the blocking part 421 will block the roller 43 so that the drawer 4 cannot be completely pulled out, thus avoiding the difficulty of reinstalling and resetting the drawer 4 after it is completely pulled out, effectively improving the user experience.

[0049] Preferably, in this embodiment, there are two drawers 4, which are arranged symmetrically and pulled out in opposite directions from the left and right ends of the bottom of the tabletop 1, making full use of the space at the bottom of the tabletop 1.

[0050] like Figure 3 As shown, the support legs 11 at the bottom rear end of the tabletop 1 have universal slots 111 for installing various external devices, including but not limited to cameras, projectors, sensors, etc., which can be detached and quickly installed. The installation methods include but are not limited to snap-fit, fastening, and plugging.

[0051] Furthermore, the support leg 11 has an internal cavity, and the tabletop 1 has a through hole 112 so that the through hole 112 is connected downward to the cavity inside the support leg 11. Users can place stationery and other items in the cavity through the through hole 112 for storage, and a cover can also be provided at the through hole 112 for opening and closing.

[0052] The reading rack 2 is detachably mounted on the rear end of the tabletop 1 via a base 21. The rear end of the tabletop 1 has a slot, and the bottom of the base 21 is inserted into the slot, enabling a detachable and quick connection with the tabletop 1.

[0053] The bottom of the reading rack 2 is hinged to the base 21 by a hinge shaft 23, which allows the reading rack 2 to flip back and forth relative to the base 21. The reading rack 2 can be flipped forward to be close to or flush with the table 1 for storage, or it can be flipped backward to place books on the reading rack 2.

[0054] like Figure 8 As shown, a backrest 211 is provided at the rear end of the base 21. After the reading rack 2 flips backward to form a set angle with the table 1, the backrest 211 abuts against the rear end of the reading rack 2, preventing the reading rack 2 from flipping backward and providing support for the reading rack 2. At this time, the angle of the reading rack 2 allows the book to be placed stably, making it convenient for the user to read.

[0055] Furthermore, refer to Figure 7 The base also has a protruding strip-shaped rib 231, which is close to the hinge shaft 23. The bottom of the reading rack is provided with a locking block 232, which is located at a radial position on the outer periphery of the hinge shaft 23. When the reading rack rotates, it synchronously drives the locking block 232 to rotate. In this embodiment, preferably, when the reading rack flips backward to a set angle and forms contact with the backrest, the locking block 232 interferes with the rib 231 as the reading rack rotates, and is squeezed and moved to the other side of the rib 231. When the reading rack contacts the backrest, the locking block 232 and the rib 231 form a certain resistance to prevent the reading rack from flipping forward, thus avoiding collisions or vibrations that could cause the reading rack to tip forward.

[0056] like Figure 1 and Figure 2 As shown, the reading rack 2 has clamps 22 on its left and right sides respectively. The two clamps 22 are arranged symmetrically. The outer side of the clamps 22 has a retaining edge 222 to abut against the left and right sides of the reading material. The clamps 22 have an elastic strip 221. The elastic strip 221 has a certain elasticity to abut against the surface of the clamps 22. The reading material can be pressed and fixed on the clamps 22 by the elastic strip 221.

[0057] Furthermore, the back of the reading rack is provided with a slide groove 24, and the clamps are slidably inserted into the slide groove 24, so that the clamps 22 can move laterally relative to the reading rack 2, and the two clamps 22 can be pulled outward to the left and right sides of the reading rack 2, increasing the distance between the two clamps 22 so that larger reading materials can be placed.

[0058] To improve the stability of the clamping plate during pulling and its self-locking capability at the desired position, refer to Figure 6 The clamping plate is also provided with an elastic sheet 223. The end of the elastic sheet 223 protrudes from the outer periphery of the clamping plate and abuts against the inner wall of the slide groove 24. The middle part of the elastic sheet 223 forms a certain elastic bend under the abutting effect of its end. The abutting force provided by the elastic bend causes the end of the elastic sheet 223 to form a certain static friction force with the inner wall of the slide groove 24, thereby increasing the damping when the clamping plate is pulled out, enhancing stability, and providing a self-locking effect.

[0059] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
