The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1 to 7, an embodiment of the present application provides a posture-correcting child chair, which includes a support base 1, a stool surface 2, and a backrest 3.

Referring to fig. 3, the supporting seat 1 includes a base 11, a vertical pillar 12, and a stool surface supporting frame 13. The stool surface 2 is connected with a stool surface support frame 13. The backrest 3 is connected with the stool surface 2. The vertical pillar 12 is fixedly connected to the base 11 and is located at the center of the base 11. The stool top support frame 13 includes a sliding sleeve 131 and a support rod 132 connected to a side wall of the sliding sleeve 131.

The sliding sleeve 131 is sleeved on the vertical pillar 12, and the sliding sleeve 131 can slide up and down along the vertical pillar 12. A height adjusting device 4 is arranged between the sliding sleeve 131 and the vertical pillar 12.

Referring to fig. 6, the height adjusting means 4 includes a first knob 41 and a first spring plate 42. The middle of the first spring plate 42 is higher than the two ends. A first spring plate accommodating chamber 133 is defined in the sliding sleeve 131. The side wall of the first spring plate accommodating cavity 133 is provided with an internal thread. The first knob 41 is provided with an external thread adapted to the internal thread. The threaded end of the first knob 41 passes through the internal thread and abuts against the middle of the first spring plate 42. Both ends of the first spring piece 42 abut against the outer wall surface of the vertical pillar 12.

Thus, after the chair height is adjusted, the first knob 41 is tightened to abut against the first spring plate 42, and the first spring plate 42 abuts against the vertical support 12, thereby preventing the sliding sleeve 131 from moving up and down relative to the vertical support 12. When the chair height needs to be adjusted, the first knob 41 is loosened, the first spring plate 42 is reset to extend, and the sliding sleeve 131 can be freely moved, so that the purpose of adjusting the chair height is achieved.

Referring to fig. 3, the support rod 132 is a diagonal rod. The lower end of the diagonal rod is connected to the center of the sliding sleeve 131 in the up-down direction, and the inclination angle adjusting device 5 is arranged between the middle part and the upper end of the diagonal rod and the stool surface 2. Specifically, the reclining device 5 includes a pushing mechanism 51 and a hinge mechanism 52. Wherein, the hinge mechanism 52 is positioned between the middle of the bottom of the stool surface 2 and the upper end of the diagonal rod. The pushing mechanism 51 is located between the rear end of the bottom of the stool surface 2 and the middle of the supporting bar 132.

The upper surface of the stool surface 2 is a cambered surface with radian of 10-15 degrees, and the middle part of the stool surface 2 is lower than the front part and the rear part. It should be noted that the stool surface 2 may also be an arc-shaped plate. The backrest 3 is connected to the stool surface 2 through a backrest connecting frame 6, the backrest connecting frame 6 is an L-shaped frame, the vertical section of the L-shaped frame is connected with the rear part of the backrest 3, and the horizontal section is connected with the bottom of the stool surface 2.

Referring to fig. 5, the hinge mechanism 52 includes a hinge shaft 521, two hinge lugs 522 disposed at the bottom of the stool surface 2, and a hinge sleeve 523 fixedly connected to the upper end of the diagonal rod. The two hinge lugs 522 are respectively positioned at the center of the stool surface 2 in the front-back direction and are arranged symmetrically left and right. The hinge sleeve 523 is located between the two hinge ears 522. The hinge shaft 521 passes through one of the hinge lugs 522, the hinge sleeve 523 and the other hinge lug 522 in sequence.

Referring to fig. 7, the push mechanism 51 includes a connection sleeve 511, a sliding rod 512, a second knob 513, and a second spring plate 514. The connecting sleeve 511 is fixedly connected to the side surface of the supporting rod 132. The upper end of the sliding rod 512 is fixedly connected with the bottom of the stool surface 2. The lower end of the sliding rod 512 is slidably connected in the connecting sleeve 511. The middle portion of the second spring plate 514 is higher than the two ends. The connection sleeve 511 defines a second spring plate accommodating chamber 515 therein. The side wall of the second spring plate accommodating cavity 515 is provided with internal threads. The second knob 513 is provided with an external thread adapted to the internal thread. The threaded end of the second knob 513 passes through the internal thread and abuts against the middle portion of the second spring plate 514. Both ends of the second spring piece 514 abut against the outer wall surface of the slide lever 512.

Thus, when the tilt angle of the chair is adjusted, the second knob 513 is tightened to abut against the second spring plate 514, and the second spring plate 514 abuts against the sliding rod 512 to prevent the sliding rod 512 from moving up and down. When the tilt angle of the chair needs to be adjusted, the second knob 513 is released, and the second spring 514 is reset to extend, so that the sliding rod 512 can be freely adjusted, because the middle part of the stool surface 2 is hinged with the supporting rod 132. Thus, the pushing mechanism 51 can push the stool surface 2 to rotate around the end of the slope rod to adjust the slope angle of the stool surface 2.

The working principle of the embodiment of the application is as follows:

when the hunchback posture of the child needs to be corrected and the forward and backward inclined sitting posture of the pelvis needs to be improved, the second knob 513 is turned and unscrewed, and the sliding rod 512 is adjusted upwards or downwards, so that the inclination angle of the stool surface can be changed, and the forward and backward inclined posture of the pelvis can be adjusted.

When the body bending mode of the spastic infant needs to be corrected, the second knob 513 is rotated, and then the sliding rod 512 is adjusted upwards, so that the stool surface is inclined downwards, and the whole body posture is in the stretching mode.

When the stretching mode of the infant needs to be corrected for the infant who is not free and has low muscle tension, the first knob 41 and the second knob 513 are turned and unscrewed, the inclination angle of the stool surface and the height of the seat are adjusted, the angle of the stool surface is inclined upwards, and the whole body posture is in the buckling mode.

The above is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
