[0031] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0032] Please see Figures 1-7In a preferred embodiment of this utility model, a spinal correction and care chair includes a seat body. Preferably, the backrest 11 and seat cushion 12 of the seat body are rotatably connected. The specific rotatable connection method is prior art and will not be described in detail here. A sliding mechanism is installed on the backrest 11 of the seat body, and a placement opening 111 is provided. A functional pad 3 is movably installed in the placement opening 111. The functional pad 3 is slidably connected to the backrest 11 via the sliding mechanism, with the sliding direction being the height direction of the backrest 11. The position of the functional pad 3 on the backrest 11 is adjusted by the sliding mechanism. Further, a rotating shaft 31 is installed on the functional pad 3, and the movable part of the sliding mechanism is rotatably connected to the rotating shaft 31. A locking mechanism is installed on the rotating shaft 31 to prevent the functional pad 3 from rotating relative to the movable part of the sliding mechanism. The functional pad 3 can rotate under the rotation of the rotating shaft 31. Preferably, the sliding mechanism includes a slider 21 and a drive rod 22. The drive rod 22 has a threaded section, and both ends of the drive rod 22 are rotatably connected to the backrest 11. The slider 21 is threadedly fitted onto the drive rod 22 through the threaded section, and the slider 21 is also slidably connected to the backrest 11. A rotating shaft 31 is rotatably connected to the slider 21. The drive rod 22 rotates to drive the slider 21 to slide along the height direction of the backrest 11. Because the slider 21 is rotatably connected, the rotating shaft 31 can be driven to slide along the height direction of the backrest 11. Since the rotating shaft 31 is mounted on the functional pad 3, the functional pad 3 can be driven to slide along the height direction of the backrest 11, thereby adjusting the position of the functional pad 3 on the backrest 11. In this embodiment, the sliding mechanism also includes a guide rod 23, which is parallel to and spaced apart from the drive rod 22. The slider 21 is slidably connected to the backrest 11 by slidingly fitting the guide rod 23. Under the action of the guide rod 23, the sliding of the slider 21 can be made more stable. More preferably, two sliders 21 are provided. One slider 21 is threadedly connected to the drive rod 22, and the other slider 21 is slidably connected to the guide rod 23. The functional pad 3 is disposed between the two sliders 21, and the two ends of the rotating shaft 31 are rotatably connected to one slider 21 respectively. Sliders 21 are provided on opposite sides of the functional pad 3. The two sliders 21 move synchronously under the action of the drive rod 22 and the guide rod 23, thereby ensuring that the functional pad 3 can move stably and smoothly relative to the sliders 21. In addition, the upper end of the drive rod 22 passes through the top of the backrest 11 and extends to the outside of the backrest 11, and is equipped with an operating handle 221 for operating the rotation of the drive rod 22. The rotation of the drive rod 22 can be easily operated by using the operating handle 221.

[0033] In this embodiment, the locking mechanism includes a locking rod 41, and the movable part has a first locking hole 211. Specifically, the movable part is a slider 21, and the rotating shaft 31 is provided with a second locking hole 311. The second locking hole 311 is aligned with and connected to the first locking hole 211 through the rotation of the rotating shaft 31 relative to the movable part of the sliding mechanism. The locking rod 41 moves through both the first locking hole 211 and the second locking hole 311 simultaneously, and the locking rod 41 and the second locking hole 311 are detachably connected. When the locking rod 41 moves through both the first locking hole 211 and the second locking hole 311 simultaneously, the rotating shaft 31 and the slider 21 are in a locked state, and the rotating shaft 31 cannot rotate relative to the slider 21. When it is necessary to unlock, it is only necessary to remove the locking rod 41 from the second locking hole 311. Preferably, the locking rod 41 is a threaded rod, and at least one of the first locking hole 211 and the second locking hole 311 is a threaded hole that matches the locking rod 41. This can prevent the locking rod 41 from accidentally coming off after passing through the first locking hole 211 and the second locking hole 311, thus preventing accidental unlocking. In particular, the first locking hole 211 is preferably a threaded hole, which can prevent the locking rod 41 from accidentally coming off the first locking hole 211 and the second locking hole 311, and prevent the locking rod 41 from falling off the first locking hole 211 when unlocking, thus avoiding loss of the locking rod 41.

[0034] Furthermore, the functional cushion 3 has two accommodating cavities arranged side-by-side along the thickness direction of the backrest 11. One cavity is equipped with a massage mechanism for massaging the back, and the other cavity is equipped with a training mechanism for training spinal flexion movements. When the functional cushion 3 rotates relative to the sliding mechanism, only one of the training mechanism or the massage mechanism is positioned on the front of the backrest 11 at a time. Preferably, the accommodating cavity containing the massage mechanism is a first accommodating cavity 32. The massage mechanism includes a first motor 321, a rotating rod 322, and a massage cylinder 323. The first motor 321 and the rotating rod 322 are installed within the first accommodating cavity 32. The output shaft of the first motor 321 is driven to one end of the rotating rod 322, and the other end of the rotating rod 322 is rotatably connected to the cavity wall of the first accommodating cavity 32. The massage cylinder 323 is fitted onto the shaft of the rotating rod 322, and a portion of the massage cylinder 323 protrudes from the surface of the functional cushion 3. Multiple massage blocks 3231 are provided on the outer wall of the massage cylinder 323. When a massage is needed, the motor is activated to rotate the rotating rod 322, which in turn rotates the massage cylinder 323. The massage cylinder 323 then rotates the massage blocks 3231 to massage the user's back. Additionally, the training mechanism is housed in a second accommodating cavity 33. The training mechanism includes an arc-shaped frame 331 for supporting the patient's lumbar spine. The arc-shaped frame 331 is installed within the second accommodating cavity 33 and partially protrudes from the surface of the functional pad 3. In this embodiment, the arc-shaped frame 331 has a plate-like structure. During training, the user's back conforms to the arc-shaped frame 331, and the curvature of the frame 331 provides bending training for the user's spine. Preferably, the arc-shaped frame 331 is elastic. Those skilled in the art can select elastic materials to make the arc-shaped frame 331 according to the actual situation, such as plastics, polymer composite materials PP / NBR, etc.; a second motor 332 is installed in the second accommodating cavity 33. The output shaft of the second motor 332 is connected to the transmission rod 333. The length direction of the transmission rod 333 is parallel to the height direction of the backrest 11, and the transmission rod 333 has a threaded section. A transmission block 334 is threadedly sleeved on the threaded section. The transmission block 334 is connected to one end of the arc-shaped frame 331; a sliding opening 335 is opened on the functional pad 3. The length direction of the sliding opening 335 is parallel to the height direction of the backrest 11, and the transmission block 334 is slidably installed on the sliding opening 335. The second motor 332 drives the transmission rod 333 to rotate, which in turn drives the transmission block 334 on the transmission rod 333 to slide along the height direction of the backrest 11. This causes one end of the arc frame 331 installed on the transmission block 334 to move as well, thereby adjusting the distance between the two ends of the arc frame 331 and thus adjusting the curvature of the arc frame 331. This allows for easy adjustment of the degree of curvature according to the user's physique or training intensity requirements, so that the degree of curvature of the arc frame 331 matches the user and improves the effect of spinal correction training.More preferably, the transmission rod 333 has threaded sections with opposite ends, and each threaded section is threaded with a transmission block 334. Each transmission block 334 is connected to one end of the arc-shaped frame 331, allowing adjustment of the bending degree of the arc-shaped frame 331 from both ends, so that it can bend in the center. It should be noted that those skilled in the art should know that this application requires power from a power module to start the first motor 321 and the second motor 332. This is a well-known and commonly used technical means and is not an improvement of this application, so it will not be described in detail. This is also omitted in the accompanying drawings. Those skilled in the art can start the motors based on common knowledge.

[0035] When using this invention, firstly, adjust the sliding mechanism according to the user's height and body type to move the functional pad 3 to a specific position on the backrest 11, so that the functional pad 3 is positioned on the user's back where massage or training is needed. If back massage is required, the massage mechanism can be rotated to the front of the backrest 11 under the action of the rotating shaft, and then locked using the locking mechanism to prevent the functional pad 3 from rotating relative to the moving part of the sliding mechanism. If spinal curvature training is required, the training mechanism can be rotated to the front of the backrest 11 using the above method and then locked. In addition, to prevent the user's back from detaching from the backrest 11 during use and affecting the nursing effect, this embodiment provides a restraint strap 5 on the backrest 11 to fix the user's back to the backrest 11. Under the restraint of the restraint strap 5, the user's back cannot detach from the backrest 11 on its own. This invention combines a massage mechanism and a training mechanism on the seat, allowing users to perform spinal correction while seated without interrupting their studies or work. Furthermore, the user can easily switch between massage and spinal correction training according to their needs, eliminating the need to change equipment for different treatment methods. Additionally, the sliding mechanism allows the position of the function pad 3 on the backrest to be adjusted according to the user's height, making it suitable for users of different heights and thus having a wide range of applications.

[0036] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
