Description

Technical Field

[0001] The utility model relates to the technical field of sitting posture correction, and more specifically to a sitting posture correction frame. Background Art

[0002] With the popularization of education, people spend more time studying at desks. Wrong sitting posture not only affects children's spinal development, but also easily damages their eyesight. For this reason, sitting posture correctors came into being. Sitting posture correctors are also called sitting posture correction frames, which are used to fix the edge of the table against the user's torso.

[0003] The sitting posture correction frame is generally composed of three parts: a table clamping mechanism, a column and a chest support. The two ends of the column are connected to the table clamping mechanism and the chest support respectively. In order to make the sitting posture correction frame adapt to users of different heights, the column adopts a telescopic structure. The most common telescopic column structure is: a locking structure is set on the outer tube, and a rack is set at the position of the inner tube corresponding to the locking structure. The locking tongue of the locking structure bites the rack to fix the telescopic column. When adjusting the height of the column, it is necessary to unlock it by pressing or rotating the locking structure, and the steps are relatively cumbersome. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] like Figure 1-11 As shown, in this embodiment, a sitting posture correction frame is disclosed, comprising:

[0042] Chest support 9;

[0043] A table clamping mechanism, which is used to fix to the edge of the table;

[0044] A telescopic column, one end of which is hinged to the table clamping mechanism and the other end is connected to the chest support 9;

[0045] Among them, the telescopic column includes an articulated seat 1, a first telescopic rod 2 that slides with the articulated seat 1, and a second telescopic rod 3 that slides with the first telescopic rod 2. A number of soft first damping rings 4 are provided between the articulated seat 1 and the first telescopic rod 2, and a number of soft second damping rings 5 ​​are provided between the first telescopic rod 2 and the first telescopic rod 2.

[0046] Furthermore, combined with Figure 8-11 As shown, in this embodiment, a notch is provided on the hinge seat 1, and one end of the telescopic column is located in the notch and is hinged to the side wall of the notch.

[0047] Furthermore, a through hole is provided on the side wall of the notch, and pivots rotatably matched with the through hole are provided on both sides of the articulated seat 1. The telescopic column can swing back and forth around the axis of the pivot relative to the table clamping mechanism. When the telescopic column rotates to the upper part of the table clamping mechanism relative to the table clamping mechanism, the articulated seat 1 abuts against the inner wall of the notch, and the soft structure on the surface of the chest support 9 faces the user's position. The telescopic column is extended by pulling the chest support 9 or the first telescopic rod 2 or the second telescopic rod 3. Under the action of the first damping ring 4 and the second damping ring 5, the relative height of the first telescopic rod 2 and the articulated seat 1 remains unchanged, and the relative height of the second telescopic rod 3 and the first telescopic rod 2 remains unchanged.

[0048] Specifically, combined Figure 1-6 As shown, the first damping ring 4 is hooped on the outer circumference of the first telescopic rod 2, or the first damping ring 4 is embedded in the inner circumference of the articulated seat 1, the first telescopic rod 2 has a first shoulder 22 adapted to the inner diameter of the articulated seat 1, the first shoulder 22 is provided with a first annular mounting groove 23, the first telescopic rod 2 is provided with a first connecting hole 11a at one end away from the articulated seat 1, and the inner diameter of the first connecting hole 11a is smaller than the inner diameter of the articulated seat 1, the second damping ring 5 is hooped on the outer circumference of the second telescopic rod 3, or the second damping ring 5 is embedded in the inner circumference of the first telescopic rod 2, the second telescopic rod 3 has a second shoulder 32 adapted to the inner diameter of the first telescopic rod 2, the second shoulder 32 is provided with a second annular mounting groove 33, the second telescopic rod 3 is provided with a second connecting hole 21 at one end away from the articulated seat 1, and the inner diameter of the second connecting hole 21 is smaller than the inner diameter of the first telescopic rod 2.

[0049] In this embodiment, the first damping ring 4 and the second damping ring 5 are respectively directly sleeved on the outer circumference of the first telescopic rod 2 and the second telescopic rod 3 by their own elasticity. In another embodiment, the first damping ring 4 and the second damping ring 5 are respectively directly molded on the outer circumference of the first telescopic rod 2 and the second telescopic rod 3 by injection molding. A connecting end 31 is provided at one end of the second telescopic rod 3 away from the first telescopic rod 2, and the connecting end 31 is used to be detachably connected to the chest support 9.

[0050] Combination Figure 3 As shown, in this embodiment, the inner diameter of the base body 11 of the articulated base 1 and the inner diameter of the first telescopic rod 2 remain unchanged along any cross-sectional area of ​​their axial direction.

[0051] Specifically, combined Figure 4 and Figure 7 As shown, in this embodiment, the articulated seat 1 comprises a seat body 11 and an end cover 12 connected to the seat body 11, a first pivoting half-shaft 11b is provided on both sides of the seat body 11, and a second pivoting half-shaft 12a is provided on both sides of the end cover 12. The first pivoting half-shaft 11b and the second pivoting half-shaft 12a are combined to form the pivot of the articulated seat 1.

[0052] Specifically, combined Figure 8-11 As shown, the table clamping mechanism includes a first clamping plate 6, a second clamping plate 7 and a plurality of locking knobs 8. The head of the locking knob 8 is located outside the first clamping plate 6, and the locking knob 8 passes through the second clamping plate 7 and is threadedly connected to the first clamping plate 6. By rotating the locking knob 8, the second clamping plate 7 is forced to move toward the first clamping plate 6.

[0053] Specifically, combined Fig.10 and Fig.12 As shown, in this embodiment, when the telescopic column rotates to the lower part of the table clamping mechanism relative to the table clamping mechanism, the chest support 9 is located below the locking knob 8. In another embodiment, when the telescopic column rotates to the lower part of the table clamping mechanism relative to the table clamping mechanism, the head of the locking knob 8 limits the chest support 9.

[0054] That is, in another embodiment, the sitting posture correction frame is used as follows:

[0055] Insert the clamping gap between the first clamping plate 6 and the second clamping plate 7 into the edge of the table, and fix the table clamping mechanism on the table by tightening the locking knob 8. At this time, the telescopic column rotates to the lower part of the table clamping mechanism relative to the table clamping mechanism, and the head of the locking knob 8 abuts against the chest support 9, that is, the locking knob 8 constrains the rotation of the telescopic column relative to the table clamping mechanism. At this time, it is necessary to pull the telescopic column downward to stretch it from the shortest length until the edge of the chest support 9 is lower than the lower edge of the locking knob 8, and the locking knob 8 is released from the constrained state of the telescopic column. Rotate the telescopic column so that the telescopic column rotates to the upper part of the table clamping mechanism relative to the table clamping mechanism, and the sitting posture correction frame can be used normally. When idle, the telescopic column can be rotated again so that the telescopic column rotates to the lower part of the table clamping mechanism relative to the table clamping mechanism, which may save space and reduce the space occupied by the sitting posture correction frame.
