[0003] In daily life, both students and office workers cannot live without desks and chairs. However, in order to relax, we often sit in an improper posture. Sitting for a long time can easily lead to hunchback and shoulder problems. Therefore, some posture correctors for desks or chairs have appeared on the market. However, their functions are relatively simple and their practicality is relatively low. Utility Model Content

[0004] The purpose of this invention is to provide a posture corrector, which aims to solve the problem that the existing posture correctors have relatively limited functions.

[0005] This utility model is a posture corrector that includes a vertically arranged support base and a clamping mechanism. The clamping mechanism is located at the bottom of the support base. A connector is protruding from the front end of the support base. The connector is fixedly connected to the support base. A posture correction component is installed on the connector. The posture correction component is horizontally arranged on the connector. The connector and the posture correction component are connected by a shaft to adjust the up-and-down swing of the posture correction component. The shaft includes a fixed shaft, which is laterally disposed on the front end of the connector. The connector and the fixed shaft are connected by screws. Rotary shafts are rotatably connected to both ends of the fixed shaft. The rotating shafts are coaxially arranged with the fixed shaft. The straightening component is rotatably connected to the fixed shaft via the rotating shafts.

[0006] Furthermore, a limiting groove is formed on the front end of the connector, the limiting groove extends laterally through the front end of the connector, and the middle of the fixed shaft has a flat connecting section recessed on both the front and rear sides, the connecting section being installed laterally in the limiting groove.

[0007] Furthermore, the fixed shaft and the connector are connected by two screws, which are arranged at intervals along the length of the connecting section to fix the fixed shaft through and to the front end of the connector.

[0008] Furthermore, an air cushion is provided on the front end of the corrective component, and a breathable cavity is formed by a transverse indentation in the middle of the front end of the air cushion.

[0009] Furthermore, the rear end of the air cushion is recessed to form an inlay groove, and an abutment plate is installed in the inlay groove. The air cushion is installed on the front end of the corrective member through the abutment plate. The corrective component has a front opening at its front end, and the outer circumferential side of the air cushion abuts against the inner circumferential side of the front opening.

[0010] Furthermore, the clamping mechanism includes a clamping part and an adjusting nut. The clamping part has an "L"-shaped structure. The upper part of the clamping part is inserted into the bottom of the support base from bottom to top, forming a vertically arranged toothed section. The bottom of the support base extends backward to form a clamping seat. The clamping seat is arranged opposite to the lower part of the clamping part. The adjusting nut is installed on the clamping seat. The adjusting nut and the clamping part are adjustablely connected through the toothed section.

[0011] Furthermore, the retaining tooth section and the adjusting nut are engaged by a wedge block. The support base is provided with a guide frame for the retaining tooth section to pass through vertically. The bottom of the guide frame is provided with a lateral guide groove for the wedge block to be inserted laterally. A spring is installed on the wedge block to drive the wedge block away from the retaining tooth section. One end of the spring abuts against the inner wall of the guide frame, and the other end of the spring abuts against the wedge block. The adjusting nut abuts against the side of the wedge block away from the retaining tooth section from top to bottom.

[0021] Reference Figures 1-6 The image shown is a preferred embodiment of the present invention.

[0022] A posture corrector includes a vertically arranged support base 10 and a clamping mechanism 20. The clamping mechanism 20 is located at the bottom of the support base 10. A connector 50 protrudes from the front end of the support base 10 and is fixedly connected to the support base 10. A corrective element 30 for posture correction is installed on the connector 50. The corrective element 30 is horizontally arranged on the connector 50. The connector 50 and the corrective element 30 are connected by a shaft 60 for adjusting the up-and-down swing of the corrective element 30. The shaft 60 includes a fixed shaft 61, which is laterally disposed on the front end of the connector 50. The connector 50 and the fixed shaft 61 are connected by screws. Rotating shafts 62 are rotatably connected to both ends of the fixed shaft 61. The rotating shafts 62 and the fixed shaft 61 are arranged coaxially. The straightening member 30 is rotatably connected to the fixed shaft 61 through the rotating shafts 62 and the fixed shaft 61.

[0023] The posture corrector described above achieves stable fixation through the vertical support base 10 and the bottom clamping mechanism 20. The connection structure between the connector 50 and the shaft 60 of the corrector 30 allows the corrector 30 to swing up and down for adjustment, adapting to different users' body shapes and sitting posture needs, thus improving the versatility of the corrector. The shaft 60 adopts a coaxial rotation design of a fixed shaft 61 and a rotating shaft 62, which not only ensures the flexibility of the corrector 30's swing but also enhances the stability of the connection structure, preventing loosening or displacement after long-term use and extending the product's service life; it also solves the problem of the posture corrector having relatively limited functionality.

[0024] In this embodiment, a limiting groove 51 is provided on the front end of the connector 50. The limiting groove 51 extends laterally through the front end of the connector 50. The middle of the fixed shaft 61 has a flat connecting section 63 recessed on both sides. The connecting section 63 is installed laterally in the limiting groove 51.

[0025] The limiting groove 51 at the front end of the connector 50 cooperates with the flat connecting section 63 of the fixed shaft 61, achieving precise positioning of the fixed shaft 61 on the connector 50, preventing lateral rotation or axial displacement of the fixed shaft 61, and ensuring the stability of the shaft 60 installation. At the same time, the transverse through-hole design of the limiting groove 51 facilitates rapid assembly of the fixed shaft 61, improving production efficiency, and the flat surface structure increases the contact area between the fixed shaft 61 and the connector 50, reducing local stress and enhancing the overall load-bearing capacity.

[0026] In this embodiment, the fixed shaft 61 and the connector 50 are connected by two screws. The two screws are arranged at intervals along the length of the connecting section 63 to fix the fixed shaft 61 through the front end of the connector 50.

[0027] Two screws are spaced apart along the length of the connecting section 63, making the fixing force distribution between the fixed shaft 61 and the connector 50 more uniform, avoiding stress concentration caused by single-point fixing, and effectively preventing the fixed shaft 61 from deforming or loosening when under force; the through-type threaded connection structure further strengthens the fixing effect, ensuring that the fixed shaft 61 always remains stable during the swing adjustment of the straightening component 30, and improving the structural reliability of the product.

[0028] In this embodiment, an air cushion 31 is provided on the front end of the corrective member 30, and a breathable cavity 32 is formed by a transverse indentation in the middle of the front end of the air cushion 31.

[0029] The air cushion 31 at the front end of the corrector 30 has good elasticity and softness. When the corrector 30 comes into contact with the user's body, it can reduce the pressure and discomfort caused by hard contact, improve the user's comfort during use, and make it easier for the user to maintain the correct sitting posture for a long time.

[0030] The air cavity 32 formed by the horizontal indentation at the front center of the air cushion 31 can increase the air circulation between the air cushion 31 and the user's body, reduce the stuffiness and sweat accumulation caused by prolonged contact, and further improve the comfort and hygiene of use.

[0031] In this embodiment, the rear center of the air cushion 31 is recessed to form an inlay groove 33, and an abutment plate 34 is installed in the inlay groove 33. The air cushion 31 is installed on the front end of the corrector 30 through the abutment plate 34. The front end of the corrective component 30 has a front opening, and the outer circumferential side of the air cushion 31 abuts against the inner circumferential side of the front opening.

[0032] The air cushion 31 is securely connected to the straightener 30 through the engagement of the insert groove 33 and the abutment plate 34, preventing the air cushion 31 from falling off or shifting during use, while also facilitating the disassembly and replacement of the air cushion 31. The front opening design of the straightener 30 ensures that the outer circumference of the air cushion 31 fits tightly against the inner wall of the opening, guaranteeing the installation stability of the air cushion 31 and limiting excessive deformation of the air cushion 31 through the edge of the opening, thus extending the service life of the air cushion 31 and facilitating cleaning and maintenance.

[0033] In this embodiment, the clamping mechanism 20 includes a clamping part 21 and an adjusting nut 22. The clamping part 21 has an "L" shaped structure. The upper part of the clamping part 21 is inserted into the bottom of the support base 10 from bottom to top, forming a vertically arranged toothed section 23. The bottom of the support base 10 extends rearward to form a clamping seat 19. The clamping seat 19 is arranged opposite to the lower part of the clamping part 21. The adjusting nut 22 is installed on the clamping seat 19. The adjusting nut 22 and the clamping part 21 are adjustablely connected through the toothed section 23. When the clamping seat 19 and the lower part of the clamping part 21 are arranged at a distance, a clamping area for clamping the edge of the table is formed.

[0034] The L-shaped clamping part 21 and the clamping base 19 are arranged opposite each other to form a clamping area, which can be adapted to the edge of the table of different thicknesses. The clamping tightness can be adjusted by adjusting the engagement of the nut 22 and the toothed section 23. The operation is simple and the fixation is firm. The design of the upper part of the clamping part 21 being inserted into the bottom of the support base 10 makes the clamping mechanism 20 and the support base 10 form an integrated structure, which enhances the overall stability, prevents the corrector from shaking during use, and ensures the correction effect.

[0035] In this embodiment, the toothed section 23 and the adjusting nut 22 are engaged by a wedge block 24. The support base 10 is provided with a guide frame 110 through which the toothed section 23 passes vertically. The bottom of the guide frame 110 is provided with a side guide groove 111 for the wedge block 24 to be inserted laterally. A spring 25 is installed on the wedge block 24 to drive the wedge block 24 away from the toothed section 23. One end of the spring 25 abuts against the inner wall of the guide frame 110, and the other end of the spring 25 abuts against the wedge block 24. The adjusting nut 22 abuts against the side of the wedge block 24 away from the toothed section 23 from top to bottom. The top of the clamping base 19 is provided with a threaded hole for the adjusting nut 22 to be inserted vertically. The adjusting nut 22 and the clamping base 19 are threadedly connected.

[0036] The design of the guide frame 110 and the side guide groove 111 provides guidance and limit for the toothed section 23 and the wedge block 24, ensuring a stable and smooth adjustment process. The toothed section 23 on the upper part of the clamping part 21 cooperates with the adjusting nut 22 through the wedge block 24. Under the action of the spring 25, the wedge block 24 can reliably engage with the toothed section 23. When the adjusting nut 22 is tightened downwards, it pushes the wedge block 24 to further clamp with the toothed section 23, thus achieving a stable fixation of the clamping part 21. When adjustment is required, the adjusting nut 22 is loosened upwards, and the spring 25 pushes the wedge block 24 away from the toothed section 23, making it easy to adjust the position of the clamping part 21. The operation is convenient and quick, and the clamping is firm and reliable, which can effectively prevent the corrector from loosening or falling off during use.

[0037] In this embodiment, a mounting position is provided on the top of the support base 10, and a distance sensor 11 is installed in the mounting position to detect whether an object is approaching from above within a set distance. The distance sensor 11 is electrically connected to the main control board 12, and the main control board 12 is electrically connected to the speaker 13. A control button 40 electrically connected to the main control board 12 is provided on one side of the support base 10. A Bluetooth module is connected to the main control board 12.

[0038] The distance sensor 11 can detect the distance between the user's head and the orthodontic device in real time. When the user's head is too close, the distance sensor 11 transmits a signal to the main control board 12, which then controls the speaker 13 to emit a reminder sound. This achieves automatic monitoring and timely reminders of the user's posture, effectively preventing myopia and spinal deformities caused by prolonged close-range eye use or hunching over. It also solves the problem of the orthodontic device having relatively limited functionality. The addition of the Bluetooth module enables the orthodontic device to wirelessly connect with smart devices such as mobile phones and tablets, supporting the uploading and analysis of posture data (such as the number of errors and usage time) (matching the APP data analysis function). Users can view historical records through the APP to help develop good posture habits.

[0039] The corrective component 30 provides physical support for the user's chest, guiding the user to maintain an upright sitting posture. Combined with sensors and reminder functions, it forms a closed-loop correction mechanism of "physical support + intelligent monitoring + active reminders", and the correction effect is significantly better than single physical correction or reminder products.

[0040] In this embodiment, the main control board 12 is installed inside the support base 10, and the main control board 12 is connected to the display screen 14, which is installed on the rear end of the support base 10.

[0041] The main control board 12 is installed inside the support base 10, which can prevent external dust and collisions from damaging the core circuit, extend the service life of the equipment, and make the appearance of the equipment simpler. The display screen 14 is installed at the rear of the support base 10 and can intuitively display the device's operating status (such as Bluetooth connection icon, timer, fill light 17 indicator, number of incorrect sitting postures, battery level, etc., which are consistent with the content displayed on the screen). Users can obtain key information in real time without operating the APP (such as the screen flashing to remind charging when the battery level is below 10%), which improves the convenience of operation. The electrical connection between the display screen 14 and the main control board 12 ensures synchronized data updates (such as automatically resetting the time to 00:00 after the timer ends and automatically recording the usage data before powering off), avoiding data delays or errors and improving the user experience.

[0042] During device use, the display screen 14 updates the number of incorrect sitting postures and usage time in real time; when the device is turned off, it automatically uploads the usage record to the APP (uploads after the next connection if there is no Bluetooth); when the battery is below 10%, the yellow battery circle on the display screen 14 flashes. Connect the device to the charger and it will be fully charged in 60 minutes (the display screen 14 is always on when the device is on and off when the device is off). The 1500mAh battery capacity supports 20 days of standby time (consistent with product parameters).

[0043] In this embodiment, a speaker hole 15 is provided on the rear end of the support base 10, and the speaker hole 15 is arranged opposite to the speaker 13.

[0044] The speaker 13 is installed inside the support base 10, which can prevent the speaker 13 from being damaged by external impact, and at the same time reduce the interference of external noise on the sound quality of the speaker 13. The speaker hole 15 at the rear end of the support base 10 is arranged opposite to the speaker 13, which can ensure that the prompt sound (such as "wrong posture" or "time is up") is clearly transmitted, and avoid the sound being blocked by the support base 10, causing the user to miss the reminder, thus ensuring the timeliness and effectiveness of the reminder. The design of the speaker 15 takes into account both sound propagation and component protection, solving the problems of easy damage to the traditional external speaker 13 and weak sound of the internal speaker 13, thus balancing practicality and durability.

[0045] In this embodiment, a lamp holder 16 protrudes outward from the rear end of the support base 10, and a supplementary light 17 is installed in the lamp holder 16. The supplementary light 17 is arranged in an inclined manner and is electrically connected to the main control board 12. The fill light 17 is arranged at an angle, which can specifically illuminate the desktop study / office area (such as books and keyboards), avoid direct light shining into the user's eyes and cause visual fatigue, and at the same time make up for the problem of insufficient ambient light (suitable for students studying at night and backlit office scenarios). The fill light 17 is electrically connected to the main control board 12 and can be controlled by the control button 40 to switch on and off and adjust the brightness (with three brightness adjustment functions). Users can adjust it flexibly according to the ambient light to meet the needs of different scenarios. The lamp holder 16 protrudes from the rear end of the support base 10, so that the illumination angle of the supplementary light 17 is more in line with the user's usage habits (such as tilting downward to illuminate the desktop), avoiding light waste and improving lighting efficiency. This design integrates posture correction and lighting functions, eliminating the need for users to use a separate desk lamp and saving desktop space. It is especially suitable for study or office scenarios with small desktop areas.

[0046] The lamp holder 16 has an outwardly arranged light-transmitting plate 18, which is arranged at an angle. Along the direction from top to bottom, the light-transmitting plate 18 is arranged at an inward angle.

[0047] The light-transmitting plate 18 covers the outside of the lamp holder 16, which can effectively prevent dust and water stains from entering the lamp holder 16, protect the fill light 17 from damage, and prevent users from directly contacting the lamp body and getting burned (especially when the lamp body gets hot after long-term use). The angle at which the light-transmitting plate 18 tilts inward from top to bottom matches the tilt angle of the supplementary light 17, which can ensure that the light is efficiently projected onto the target area (desktop) after passing through the light-transmitting plate 18, reducing light refraction loss and improving lighting brightness and uniformity. The inward-sloping light-transmitting panel 18 can further prevent light leakage (such as upward-scattered light), reduce ambient light pollution, and at the same time prevent light from irritating the user's eyes, optimize lighting comfort, and solve the problems of light scattering and poor lighting effect of traditional supplementary lights 17.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
