[0027] refer to Figures 1 to 3 The embodiment of the present application provides a quick-adjustable shoulder strap, comprising a waist belt 10, a shoulder strap 20 and an adjustment strap 30. The waist belt 10 has a front side portion 11 and a rear side portion 12 opposite to each other. The shoulder strap 20 is a double-shoulder strap type, comprising two shoulders 21 for wearing on both sides of the shoulders, and at the same time, the two ends of the two shoulders 21 close to each other are connected as a whole, namely a front shoulder 211 and a rear shoulder 212, wherein the front shoulder 211 is connected to the front side portion 11, and a V-shaped structure 201 is formed between the two shoulders 21 at one end close to the front side portion 11 and the rear side portion 12, respectively, and at the same time, the width of the two ends of the V-shaped structure 201 is smaller than the width of the middle portion, wherein the rear shoulder 212 is connected to the front shoulder 211 by the adjustment strap. The section belt 30 is movably connected to the rear side portion 12, so that the rear shoulder portion 212 can be relatively close to or away from the rear side portion 12. In this way, when adjusting the distance between the rear shoulder portion 212 and the rear side portion 12 by adjusting the belt 30, that is, when adjusting the shoulder length, based on the special structural design of the double V-shaped structure 201 formed between the two shoulders 21, the size of the shoulder width can also be adjusted synchronously, so that the adjustment of the shoulder length and shoulder width can be completed at the same time through one-step operation, which can be operated by one person, and the adjustment is convenient, fast and easy to use.

[0028] In one embodiment, the rear portion 12 is provided with a first connecting strap 13 at one end near the rear shoulder portion 212. The width of the first connecting strap 13 is greater than the width of the adjustment strap 30. The first connecting strap 13 is connected to the rear shoulder portion 212 via the adjustment strap 30. This reduces the length of the adjustment strap 30 to a certain extent, while also increasing the contact area with the user through the wider first connecting strap 13, thereby improving the structural strength and comfort of the harness.

The adjustment strap 30 has a fixed end 31 and a movable end 32 opposite to each other, wherein the fixed end 31 is fixed to the first connecting strap 13, and the movable end 32 passes through the fixing buckle 213 and then passes out of the fixing buckle 213. In this way, the adjustment strap 30 can be fixed by the fixing buckle 213 after being adjusted into place, so that the shoulder strap can be better maintained in the adjusted position.

[0030] Further preferably, the fixing buckle 213 includes a fixing frame 2131 and a buckle wrench 2132, and the fixing frame 2131 is installed on the rear shoulder 212. A movable groove is provided on the side of the fixing frame 2131 away from the rear shoulder 212. The buckle wrench 2132 is hingedly provided in the movable groove. The buckle wrench 2132 includes a pressing portion and a movable portion connected at a predetermined angle, the pressing portion being close to the bottom of the movable groove, and when the movable portion gradually moves away from the bottom of the groove along the hinge direction, the gap between the buckle wrench 2132 and the bottom of the groove gradually increases, thereby enabling the adjustment strap 30 to be unlocked and then pulled out. In addition, when the movable portion gradually approaches the bottom of the groove along the hinge direction, the pressing portion gradually approaches the bottom of the groove, thereby enabling the adjustment strap 30 to be locked and fixed, so that it can be stably maintained in the adjusted position, and is convenient to use.

[0031] In one embodiment, the fixed end 31 of the adjusting strap 30 is connected to the first connecting strap 13, and the movable end 32 is embedded in the rear shoulder 212 and extends from the fixed buckle 213, thereby increasing the structural connection strength between the adjusting strap 30 and the first connecting strap 13 and the rear shoulder 212.

[0032] In one embodiment, the rear shoulder portion 212 is provided with a connecting slot 202, and the opening of the connecting slot 202 is provided at the end of the rear shoulder portion 212. The movable end 32 passes through the connecting slot 202 and extends from the fixing buckle 213, so that when the shoulder length is shortened for a larger size, the first connecting strap 13 can be directly inserted into the connecting slot 202, thereby increasing the adjustment range of the shoulder length of the shoulder strap and having a wide range of applications. In addition, the cooperation between the first connecting strap 13 and the connecting slot 202 makes the overall structure of the shoulder strap more compact and can also improve the stability of the shoulder strap to a certain extent.

[0033] In one embodiment, the adjustment strap 30 is provided with height size marks 33 along the length direction, so that the adjustment strap 30 can be pre-adjusted into place directly according to the height size when wearing the brace, which is more convenient and standardized to use.

[0034] In one embodiment, combined Figure 4 and Figure 5 The waist belt 10 is provided with an adjustment knob 40, which includes a housing 41, a rotating cover 42, and a button 43. A first engaging portion 411 is provided in the housing 41. The rotating cover 42 is elastically connected to the top of the housing 41. The rotating cover 42 is provided with a second engaging portion 421 that engages with the first engaging portion 411. A micro-adjustment strap 422 is connected to the outer surface of the second engaging portion 421. The other end of the micro-adjustment strap 422 is connected to the side of the waist belt 10 away from the adjustment knob 40. The button 43 is symmetrically arranged on both sides of the housing 41 with the first engaging portion 411 as the axis of symmetry. The button 43 is provided with an inclined surface structure 431, which abuts against the bottom of the second engaging portion 421. The thickness of the inclined surface structure 431 at the end closer to the housing 41 is smaller than the thickness of the inclined surface structure 431 at the end farther from the housing 41. During the process of pressing the button 13, the rotating cover 42 is gradually moved away from the first engaging portion 411 through the inclined structure 431. When the first engaging portion 411 and the second engaging portion 421 are disengaged, the rotating cover 42 can be rotated to adjust the length of the micro-adjustment belt 422, thereby quickly adjusting the waist size.
