Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] Please see Figures 1-5 This is the first embodiment of the present invention, which provides a seat with an anti-hunchback structure, including a seat body 100. The seat body 100 includes a seat base 101 for support, casters 102 mounted on the bottom of the seat base 101 for movement, a seat cushion 103 mounted on the top of the seat base 101, and a backrest 104 connected to the side surface of the seat cushion 103; and, The anti-hunchback component 200 includes a lateral adjustment part 203 connected to the bottom surface of the seat cushion 103, an anti-hunchback backrest 201 connected to the end of the lateral adjustment part 203 for correcting sitting posture and preventing hunchback, and a height adjustment part 202 connected to the anti-hunchback backrest 201.

[0018] Preferably, the anti-hunchback 201 includes a housing 201a disposed on one side of the seat cushion 103, a drive motor 201b installed inside the cavity of the housing 201a, and an active bevel gear 201c disposed inside the cavity of the housing 201a and connected to the output end of the drive motor 201b.

[0019] Preferably, the anti-hunchback 201 further includes a first bearing 201d fitted and mounted on the upper surface of the housing 201a, a rotating shaft 201e that passes through and is connected inside the first bearing 201d, a driven bevel gear 201f connected to the end of the rotating shaft 201e and meshing with the driving bevel gear 201c, a movable plate 201g connected to the top of the rotating shaft 201e, and a correction rod 201h disposed above the movable plate 201g.

[0020] In practical use, when the drive motor 201b is running, it can drive the active bevel gear 201c to rotate. When the active bevel gear 201c rotates, it can generate a force on the driven bevel gear 201f through the meshing structure. When the driven bevel gear 201f is subjected to the force, it can drive the rotating shaft 201e to rotate inside the first bearing 201d. The rotation of the rotating shaft 201e can drive the corrective rod 201h to rotate through the movable plate 201g. When the corrective rod 201h rotates 90°, the horizontal part of the corrective rod 201h is placed across the student's chest, thereby correcting the student's sitting posture.

[0021] Working principle: When using this chair, first connect the drive motor 201b to an external power source. When the student sits on the surface of the seat cushion 103, the drive motor 201b can be run. When the drive motor 201b runs, it can drive the active bevel gear 201c to rotate. When the active bevel gear 201c rotates, it can drive the rotating shaft 201e to rotate through the driven bevel gear 201f. When the rotating shaft 201e rotates, it can drive the correction rod 201h to rotate through the movable plate 201g. After the correction rod 201h rotates 90° towards the backrest 104, the horizontal part of the correction rod 201h can be placed against the student's chest, thereby adjusting the student's sitting posture and preventing back curvature during learning. Example 2

[0022] Please see Figures 1-5 This is the second embodiment of the present invention, which provides a seat with an anti-hunchback structure.

[0023] The height adjustment part 202 is disposed between the movable plate 201g and the straightening rod 201h. The height adjustment part 202 includes a linkage block 202a connected to the surface of the straightening rod 201h, an adjustment screw 202b passing through the interior of the linkage block 202a, a second bearing 202c sleeved on the end of the adjustment screw 202b and fitted onto the surface of the movable plate 201g, and a first guide rod 202d inserted into the end of the straightening rod 201h and connected to the upper surface of the movable plate 201g.

[0024] In practical use, when the straightening rod 201h is subjected to a force, it can slide on the surface of the first guide rod 202d, which can limit the movement direction of the straightening rod 201h.

[0025] Preferably, the linkage block 202a and the adjusting screw 202b are threaded together.

[0026] In practical use, when the adjusting screw 202b rotates, it can drive the linkage block 202a to move longitudinally through the threaded connection. The longitudinal movement of the linkage block 202a can drive the straightening rod 201h to move longitudinally, thereby adjusting the height of the straightening rod 201h.

[0027] The rest of the structure is the same as in Example 1.

[0028] Working principle: Under the limiting action of the first guide rod 202d, rotating the adjusting screw 202b can drive the linkage block 202a to move longitudinally. The longitudinal movement of the linkage block 202a can drive the correcting rod 201h to move longitudinally, thus adjusting the height of the correcting rod 201h, so that the correcting rod 201h can be adapted to students of different heights. Example 3

[0029] Please see Figures 1-5 This is the third embodiment of the present invention, which provides a seat with an anti-hunchback structure.

[0030] Preferably, a lateral adjustment part 203 is connected between the housing 201a and the seat cushion 103. The lateral adjustment part 203 includes a connecting rod 203a connected to the bottom side of the housing 201a, a sliding sleeve 203b connected to the end of the connecting rod 203a, and a second guide rod 203c that passes through the interior of the sliding sleeve 203b and is connected to the bottom of the seat cushion 103.

[0031] In practical use, when the sliding sleeve 203b is subjected to a force, it can slide on the surface of the second guide rod 203c, so that the movement direction of the connecting rod 203a can be restricted by the sliding sleeve 203b.

[0032] Preferably, the lateral adjustment part 203 further includes a threaded tube 203d that passes through the middle of the connecting rod 203a, a threaded rod 203e that passes through the inside of the threaded tube 203d, and a bearing seat 203f that is sleeved on the surface of the threaded rod 203e and connected to the bottom of the seat cushion 103.

[0033] In practical use, when the threaded rod 203e rotates, it can drive the threaded tube 203d to move laterally through the threaded connection. When the threaded tube 203d moves laterally, it can drive the connecting rod 203a to move laterally. Thus, through the lateral movement of the anti-hunchback 201, the position of the straightening rod 201h can be adjusted.

[0034] The rest of the structure is the same as in Example 2.

[0035] Working principle: Under the limiting action of the sliding sleeve 203b and the second guide rod 203c, the rotation of the threaded rod 203e can drive the threaded tube 203d to move laterally. The lateral movement of the threaded tube 203d can drive the connecting rod 203a to move laterally. The lateral movement of the connecting rod 203a can drive the housing 201a to move laterally. The lateral movement of the housing 201a can be achieved through the first bearing 201d, the rotating shaft 201e, the movable plate 201g, the second bearing 202c, the adjusting screw 202b, and the lateral movement of the correcting rod 201h. This allows adjustment of the lateral position of the correcting rod 201h. In this way, the distance between the horizontal position of the correcting rod 201h and the backrest 104 after rotation can be adjusted, thus adapting to the use of students of different body types.
