[0036] When in use, by turning the adjustment knob 61, the two abdominal components 31 are pulled toward each other through the elastic rope 62 to achieve the effect of adjusting the tightness, and the adjustment knob 61 is a one-way adjustment knob, which can effectively prevent the human body's muscles from contracting and expanding to affect the tightness of the optimally adjusted abdominal component 31. After use, the adjustment knob 61 can be pressed to loosen it, making it easier for the user to put on and take off.

[0037] In addition, other structures similar to the quick lacing buckle are prior art, and the specific structures are not described in detail. For example, the structure of the no-tie knob disclosed in patent CN218737504U, the structure of the rotating shoe buckle for conveniently adjusting the tightness of the shoelace disclosed in CN 219645167 U, or other structures that can achieve this function can also be used as a substitute.

[0038] Furthermore, the brace waist 12 is also provided with two reinforcing fixing belts 9, one end of the two reinforcing fixing belts 9 is fixed to the brace waist 12, and the other end extends forward and can be connected at the brace abdomen 3. In one embodiment, the two reinforcing fixing belts 9 are provided with Velcro at adjacent sections, and can be bonded together by Velcro to achieve tightening of the abdomen. The abdomen can be further tightened by the reinforcing fixing belts 9, and the abdomen component 31 can be tightened with the knob adjustment component 6 to further tighten it for a second time, and the tightening effect is good.

[0039] Furthermore, in the self-traction lumbar brace, a second stretching belt 7 is provided between the brace waist 12 and the brace belly 3, the second stretching belt 7 passes through the fixing ring 10 and extends to the lower part of the brace body 1, and a handle 8 is provided at the end of the first stretching belt 5 and / or the second stretching belt 7.

[0040] In one embodiment, the second stretching belt 7 is located on the mid-axillary line on both sides of the body, is led out from the vest-shaped brace body 1 and passes through a pair of fixing rings 10. After tightening the reinforcing fixing belt 9, both hands hold the handles 8 of the second stretching belt 7 on both sides and apply force vertically downward to achieve traction on the lumbar spine. In addition, when in use, the first stretching belt 5 and the second stretching belt 7 are independent of each other and do not affect or pull each other.

[0041] In one embodiment, the handle 8 is a hollow ring or a handle that is narrow at the top and wide at the bottom, which is convenient for holding and pulling operations.

[0042] Based on the above structure, when using, the user can stand and use it. After wearing the brace, the cross-set first stretching belt 5 passes downward through the fixing rings 10 on both sides of the axillary midline of the vest-shaped brace body 1 and connects to the handle 8. The abdominal component 31 is tightened by the knob adjustment component 6 and fixed with the assistance of the reinforced fixing belt 9. When the waist belt is tightened appropriately, when both hands hold the handle 8 and exert force to the outside and rear of the body, the user can perform a waist extension movement. That is, by pulling the handle 8 of the first stretching belt 5 downward and outside the body, the force is transmitted to the fixed point in front of the brace shoulder 2 along the cross-set first stretching belt 5. At this time, the tension is transmitted to the abdominal component 31 and the strengthening fixing belt 9 through the fixing buckles 21 of the shoulders. The tightened abdominal component 31 and the strengthening fixing belt 9 are lifted up together with the abdomen under the action of the tension. At the same time, because the mid-axillary line fixing ring 10 is located in front of the waist and back limit fixer 4, i.e., the butterfly disc, the butterfly disc under the action of the tension is forced to move forward to the body, generating a pushing effect on the waist and back. At this time, the force F acting on the waist and back limit fixer 4 (butterfly disc) area can be decomposed into a forward thrust F1 and a downward force F2 of the hand according to the parallelogram law. At this time, the abdominal component 31 and the strengthening fixing belt 9 contract the abdomen and push the waist in the butterfly disc area, jointly realizing the effect of "contracting the abdomen and pushing the waist", achieving the purpose of reducing the pressure of the abdomen and abdominal contents on the lumbar spine, assisting the core muscle groups such as the waist and back muscles, completing a combined training, and reshaping the treatment and rehabilitation purpose of the physiological lordosis of the lumbar spine.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
