If the sitting posture is not correct during the process of writing at a desk, it is very easy to cause spinal deformation or affect eyesight, etc.; while through the sitting posture corrector, effective correction can be carried out to avoid incorrect sitting postures.

[0003] The sitting posture corrector includes a chest support component that contacts and supports the human chest and a fixing component that fixes the chest support component to the desktop. However, the existing chest support components generally include two chest support structures arranged left and right, and the two chest support structures are fixed to each other and immovable, with a small application range and unable to adapt to different chest shapes of different users. Therefore, it may cause discomfort to users during use. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a chest support structure of a sitting posture corrector, which is used to solve the technical problems that the chest support structure of the prior art mentioned in the background art cannot be adjusted left and right, cannot adapt to different chest shapes of different users, and has a small application range.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A chest support structure of a sitting posture corrector, characterized by comprising:

[0007] A top chest plate;

[0008] Two sliders. There is a cavity inside the top chest plate, and a square limiting frame is horizontally fixed on the inner wall of the cavity. The two sliders are embedded in the limiting frame and are symmetrically arranged;

[0009] A linkage rod, the linkage rod is rotatably installed in the limiting frame, and two threaded portions with opposite thread directions are provided on the outer wall of the linkage rod. Threaded holes for the two ends of the linkage rod to pass through and be threadedly adapted to the threaded portions at the corresponding two ends are respectively opened on the two sliders;

[0010] Two connecting columns, the two connecting columns are respectively fixed at one end of the two sliders, and two limiting holes for the two connecting columns to pass through are opened on the top chest plate, and the limiting holes are communicated with the cavity; <()

[0011] Two top chest members, one ends of the two top chest members are respectively fixed to one ends of the corresponding two connecting columns passing through the limiting holes.

[0012] Working Principle:

[0013] When using the product in the unfolded state, drag one of the chest pressing parts at the left / right end outward and translate it by the actual required distance. The chest pressing part at the left end drives the slider at the left end to move along the limit frame through the connecting column. The slider at the left end drives the linkage rod to rotate, and the linkage rod drives the slider at the right end to move along the limit frame. The two sliders move the same distance in two opposite directions respectively. The slider at the right end drives the chest pressing part at the right end to move through the connecting column. Under the action of the linkage rod, the two sliders and the limit frame, the chest pressing parts at the left / right ends will each translate the same distance to both sides. Therefore, no matter which one of the chest pressing parts at the left / right end is dragged, the other will automatically translate the same distance in the opposite direction.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model realizes the position adjustment of the two chest pressing parts by setting the linkage rod and the two sliders. And only by dragging one of the chest pressing parts at the left / right end, the other will automatically translate the same distance in the opposite direction, so that the chest pressing parts at the left / right ends can move away from or close to each other. The operation is convenient and simple, effectively adjusting the distance between the two chest pressing parts, facilitating the use of people with different usage requirements, and having a large scope of application.

Detailed implementation manners

[0025] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] As Figure 1-4 , shown in Fig. 8, a chest support structure of a sitting posture corrector includes:

[0027] Top chest plate 1;

[0028] Two sliders 2, a cavity 3 is provided in the top chest plate 1, a square limit frame 4 is horizontally fixed on the inner wall of the cavity 3, and the two sliders 2 are embedded in the limit frame 4 and symmetrically arranged;

[0029] Linkage rod 5, the linkage rod 5 is rotatably installed in the limit frame 4, two threaded parts with opposite thread directions are provided on the outer wall of the linkage rod 5, and two threaded holes 6 are respectively provided in the two sliders 2 for the two ends of the linkage rod 5 to pass through and be threadedly adapted to the threaded parts at the corresponding two ends. Moving the left slider 2 drives the linkage rod 5 to rotate, the linkage rod 5 drives the right slider 2 to slide, and the moving direction of the right slider 2 is opposite to that of the left slider 2. The two sliders 2 move simultaneously and move the same distance;

[0030] Two connecting columns 7, the two connecting columns 7 are respectively fixed at one end of the two sliders 2, and two limit holes 8 for the two connecting columns 7 to pass through are provided in the top chest plate 1. The limit holes 8 are communicated with the cavity 3, and the connecting columns 7 can move along the limit holes 8. The limit holes 8 limit the moving direction and distance of the connecting columns 7;

[0031] Two top chest members 9, one end of each of the two top chest members 9 is fixed to one end of the corresponding two connecting columns 7 passing through the limit holes 8, and a mounting groove 26 for the connecting columns 7 to be clamped is fixed at one end of the top chest member 9.

[0032] As Figure 2 , 3As shown in FIGS. 5 and 6, one end of the top chest plate 1 is provided with a cover plate 10, the cover plate 10 covers the cavity 3, two limiting holes 8 are symmetrically formed in the cover plate 10, four mounting columns 11 distributed in a rectangle are fixed on the inner wall of the cavity 3, four fixing columns 12 corresponding to the four mounting columns 11 respectively are fixed on the inner side of the cover plate 10, the mounting column 11 is provided with a fixing groove 13 for the fixing column 12 to be clamped, and the inner side of the cover plate 10 can be abutted against one end of the four mounting columns 11.

[0033] As Figure 3 shown in FIGS. Figure 6 6 and 7, the linkage rod 5 includes a left-handed threaded rod 14, a right-handed threaded rod 15 and an annular block 16. The left-handed threaded rod 14 and the right-handed threaded rod 15 are respectively fixed at both ends of the annular block 16. The tops of the left-handed threaded rod 14 and the right-handed threaded rod 15 are respectively abutted against the two inner side walls of the limiting frame 4. The ends of the left-handed threaded rod 14 and the right-handed threaded rod 15 abutting against the inner side wall of the limiting frame 4 are both spherical parts 23. When the left-handed threaded rod 14 and the right-handed threaded rod 15 rotate, the two tops thereof abutting against the two inner side walls of the limiting frame 4 play a role in supporting the rotation of the linkage rod 5, making the rotation movement of the linkage rod 5 more stable and the linkage rod 5 not prone to position deviation.

[0034] As Figure 3 shown in FIGS. 5 6, 7 and 8, a first limiting block 17 is fixed in the limiting frame 4. The first limiting block 17 is provided with a first arc-shaped groove 18. Two ends of the first limiting block 17 are provided with first notches 19 communicating with the first arc-shaped groove 18. A second limiting block 20 is fixed on the inner side of the cover plate 10. The second limiting block 20 is provided with a second arc-shaped groove 21. Two ends of the second limiting block 20 are provided with second notches 22 communicating with the second arc-shaped groove 21. The second limiting block 20 can be embedded into the limiting frame 4 and abutted against one end of the first limiting block 17. The first arc-shaped groove 18 and the second arc-shaped groove 21 cooperate to form an annular groove for the annular block 16 to be embedded. The two first notches 19 and the corresponding two second notches 22 cooperate to form two round holes respectively for the corresponding left-handed threaded rod 14 and the right-handed threaded rod 15 to pass through. The annular block 16 in the middle of the linkage rod 5 is embedded in the first limiting block 17 and the second limiting block 20 provided on the top chest plate 1 and the cover plate 10. Therefore, when the linkage rod 5 rotates, no other position deviation except rotation will occur.

[0035] As Figure 3 shown in FIGS. 5As shown in FIGS. 6 and 7, two symmetrically arranged support ribs 24 are horizontally fixed to the inner wall of the cavity 3 and are located within the limit frame 4. Two symmetrically arranged limit ribs 25 are horizontally fixed to the inner side of the cover plate 10. The two limit ribs 25 can be embedded into the limit frame 4. The two ends of the two sliders 2 can respectively abut against one end of the corresponding two support ribs 24 and the two limit ribs 25. By arranging the cooperation of the two support ribs 24 and the two limit ribs 25, a certain supporting and guiding effect can be exerted on the two sliders 2, so that when the two sliders 2 move, their movement stability can be ensured.

[0036] The specific operation method of the present utility model is as follows:

[0037] When the product is unfolded and used: One of the chest pressing members 9 at the left and right ends is dragged outward and translated to the actual required position. The left chest pressing member 9 drives the left slider 2 to move along the limit frame 4 through the connecting column 7. The left slider 2 drives the left-handed threaded rod 14 to rotate. The left-handed threaded rod 14 drives the right-handed threaded rod 15 to rotate through the annular block 16. The right-handed threaded rod 15 drives the right slider 2 to move along the limit frame 4. The two sliders 2 move the same distance, and the moving directions of the two sliders 2 are opposite. The right slider 2 drives the right chest pressing member 9 to move through the connecting column 7. Under the action of the linkage rod 5, the limit frame 4 and the two sliders 2, the two chest pressing members 9 will each translate the same distance to both sides. Therefore, no matter which one of the left / right chest pressing members 9 is dragged, the other will automatically translate the same distance in the opposite direction.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
