Posture-correcting chairs are important tools to help children maintain correct posture. One type of chair has the following structure:

[0003] 1. Backrest: It conforms to the curve of the back, provides back support, helps children keep their spine straight, reduces back pressure, and prevents hunchback;

[0004] 2. Footrest: Provides a place for children to place their feet, allowing their legs to be in a comfortable and relaxed state, and helping to maintain a correct sitting posture.

[0005] 3. Knee pads: They can rotate 360 ​​degrees and adjust according to the child's leg movements and postures, protecting the knees and helping to correct leg position.

[0006] 4. Chest support: The chest support structure is installed on the bracket and has six adjustable positions to adapt to different children's body sizes, providing appropriate chest support, preventing children from bending over excessively, and guiding them to sit correctly.

[0007] 5. Seat cushion: Provides a comfortable seating surface; its soft material reduces pressure on the buttocks.

[0008] 6. Stable carbon steel five-claw base: Provides stable support, distributes the weight of the chair and child, and ensures that the chair is not easy to tip over during use, thus ensuring safety.

[0009] Children vary greatly in body size, especially in the distance from their back to their chest. For children with a smaller distance from their back to their chest, the chest support may not provide effective support, while for children with a larger distance from their back to their chest, it may cause pressure and tension, resulting in poor comfort and reduced effectiveness of posture correction. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a chair for correcting posture, which solves the technical problem that the chest support part cannot provide effective support for children with small back-to-chest dimensions, while it can easily cause pressure and tension for children with larger back-to-chest dimensions, resulting in poor comfort and reduced posture correction effect.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A chair for correcting posture includes a frame, a chest support mechanism on the outside of the frame, and an adjustment mechanism on the outside of the frame for adjusting the position of the chest support mechanism. The adjustment mechanism includes a channel, a lead screw, an adjustment block, a through hole, and a handle.

[0028] This application provides a posture-correcting chair that effectively solves the technical problem that the chest support cannot provide effective support for children with small back-to-chest dimensions, while for children with larger back-to-chest dimensions, it can cause pressure and tension, resulting in poor comfort and reduced posture correction effect.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the problem that for children with smaller back-to-chest dimensions, the chest support part cannot provide effective support, while for children with larger back-to-chest dimensions, it easily causes pressure, leading to tension in the child's body, resulting in poor comfort when the child uses it, and thus reducing the effectiveness of posture correction. The overall idea is as follows:

[0031] To address the problems existing in the prior art, this utility model provides a chair for correcting sitting posture, including a support 1, a chest support mechanism 2 externally disposed on the support 1, and an adjustment mechanism for adjusting the position of the chest support mechanism 2 externally disposed on the support 1. The adjustment mechanism includes a channel 3, a lead screw 4, an adjustment block 5, a through hole 6, and a handle 7. The channel 3 is opened on the outside of the support 1, the lead screw 4 is rotatably connected to the inside of the channel 3, the adjustment block 5 is threadedly connected to the outside of the lead screw 4, the chest support mechanism 2 is disposed at the upper end of the adjustment block 5, the through hole 6 is opened on the outside of the support 1 and communicates with the inside of the channel 3, and the handle 7 is fixedly installed on the outside of the lead screw 4 through the through hole 6.

[0032] A limiting ring 8 is fixedly installed on the outside of the handle 7, and the limiting ring 8 is located inside the channel 3.

[0033] The chest support mechanism 2 has a fixing groove 9 on one side corresponding to the adjusting block 5. The chest support mechanism 2 is snapped onto the outside of the adjusting block 5 through the fixing groove 9. The chest support mechanism 2 has a guide hole 11 on the side close to the fixing groove 9. The guide hole 11 communicates with the inside of the fixing groove 9. A bolt 12 is rotatably connected inside the guide hole 11. The adjusting block 5 has an installation groove 14 on the outside. A threaded block 13 is snapped into the inside of the installation groove 14. A threaded hole 10 is opened on the outside of the threaded block 13. The bolt 12 is threaded into the inside of the threaded hole 10 through the guide hole 11.

[0034] Each side of channel 3 away from through hole 6 has a support hole 15, and the end of lead screw 4 away from handle 7 is rotatably connected to the inside of support hole 15.

[0035] Adjustment Mechanism: Channel 3 provides space for the installation and movement of lead screw 4 and adjustment block 5. Lead screw 4, through its own rotation, converts the rotational movement of handle 7 into the linear movement of adjustment block 5, thereby achieving precise adjustment of the position of chest support mechanism 2. Adjustment block 5 connects lead screw 4 and chest support mechanism 2, and moves under the drive of lead screw 4, thereby adjusting the position of chest support mechanism 2 on bracket 1 to adapt to different users' body conditions. Through hole 6 serves as the structure connecting handle 7 and lead screw 4, allowing handle 7 to be installed on lead screw 4 and rotated through through hole 6. Handle 7 is the direct component for users to operate the adjustment mechanism. By rotating handle 7, lead screw 4 can be rotated, thereby adjusting the position of chest support mechanism 2. The operation is simple and convenient, improving the ease of use of the chair.

[0036] Limiting ring 8: Limits the axial displacement of handle 7 during rotation, preventing handle 7 and lead screw 4 from disengaging from the inside of channel 3;

[0037] Fixed slot 9: Used to engage the adjusting block 5, enabling a detachable connection between the chest support mechanism 2 and the adjusting block 5, facilitating disassembly when the chest support mechanism 2 is not needed, and meeting different usage requirements;

[0038] Guide hole 11: communicates with the inside of the fixing groove 9, provides guidance for the rotation and movement of bolt 12, and ensures that bolt 12 can be connected and separated from threaded hole 10 on threaded block 13;

[0039] Bolt 12: By rotating within the guide hole 11, it can be threadedly connected or disconnected from the threaded hole 10 on the threaded block 13, thereby fixing and disassembling the chest protection mechanism 2 and the adjusting block 5. The operation is simple and the connection is firm.

[0040] Mounting slot 14 and threaded block 13: Mounting slot 14 is used to engage threaded block 13, providing an installation position for threaded block 13;

[0041] Support hole 15: Provides support for lead screw 4 to ensure the stability of lead screw 4 during rotation.

[0042] Working principle:

[0043] The first step is that when the user is using the chair, the position of the chest support mechanism 2 can be adjusted according to the body condition. That is, the handle 7 is turned to drive the lead screw 4 to rotate. Since the lead screw 4 and the adjusting block 5 are connected by threads, the lead screw 4 will drive the adjusting block 5 to move. At this time, the adjusting block 5 will drive the chest support mechanism 2 to move until the chest support mechanism 2 moves to the appropriate position. At this time, the handle 7 can be stopped.

[0044] The second step is to rotate the bolt 12 to disconnect the bolt 12 from the threaded hole 10 when the chest support mechanism 2 is no longer needed. Then, pull the chest support mechanism 2 upward to disconnect the adjusting block 5 from the fixing groove 9. At this time, the chest support mechanism 2 is disassembled.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
