[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. The "upper", "lower", "front" and "back" mentioned in this embodiment all refer to the positional relationship of the bra relative to the human body after it is worn on the human body.

[0024] like Figures 2 to 4As shown, a bra with adjustable back ratio comprises a cup 1, a back ratio 2 and a shoulder strap structure 4, wherein the two cups 1 are located in the middle part, and the part where the two cups 1 are connected forms a heart 5, and the two back ratios 2 are respectively arranged on the outsides of the two cups 1, and the two shoulder strap structures 4 respectively connect the top ends of the cups 1 and the upper ends of the back ratios 2 on the same side near the outsides, and a binding structure 23 is arranged on the back ratio 2, and the binding structure 23 is arranged as a cross structure for adjusting the fat on both sides of the chest and the back, and an adjusting part 3 is arranged near the back ratio 2 of the shoulder strap structure 4. The adjusting part 3 comprises a fixed end 31 and an adjusting end 32, and one end of the fixed end 31 and the adjusting end 32 are both connected to the shoulder strap structure 4, and the other end of the adjusting end 32 is slidably connected to the lower part of the back ratio 2, thereby achieving a good shaping and adjustment effect, and at the same time, when the bra is worn for too long and the elasticity of the back ratio is reduced, the back ratio can be adjusted by the sliding connection of the adjusting end, while ensuring the beauty, the comfort of the one-line bra can be taken into account for a long time, and the problem of the elasticity of the back ratio being easily invalidated is effectively solved.

[0025] The binding structure 23 includes a first binding rib 231 and a second binding rib 232. The first binding rib 231 and the second binding rib 232 cross at the middle or near the middle of the rear portion 2. The first binding rib 231 and the second binding rib 232 are both made of high elastic material.

[0026] Specifically, an upper tie 21 is provided at the upper end of the back ratio 2, and a lower tie 22 is provided at the lower end of the back ratio 2, wherein one end of a first tie rib 231 is connected to the outer side of the cup 1, and the other side of the first tie rib 231 is connected to the lower tie 22, and one end of a second tie rib 232 is connected to the upper tie 21, and the other end of the second tie rib 232 is connected to the lower tie 22, and the connection part is close to the outer side of the cup 1. The cross-arranged tie structure has the effect of pushing the fat and accessory breasts on both sides inward, and has the effect of supplementing and adjusting the straight back ratio.

[0027] Furthermore, a connecting buckle 41 is provided on the shoulder strap structure 4 near the rear ratio 2, and the top end of the adjustment part 3 is detachably connected to the connecting buckle 41. The fixed end 31 and the adjustment end 32 of the adjustment part 3 are both configured as belt structures, and the fixed end 31 and the adjustment end 32 form an eight-shaped structure, so that the adjustment structure 3 can cover a larger range of the rear ratio 2, thereby increasing the adjustment area of ​​the rear ratio 2.

[0028] Furthermore, a buckle 24 is provided at one end of the back ratio 2 away from the cup 1, and the two cups 1 are overlapped and connected as a whole through the buckle 24. The lower end of the fixed end 31 is connected to the buckle 24, and the lower end of the adjustment end 32 is connected to the inside of the lower bundle 22. Therefore, effective lifting and adjustment can be formed for the end and the middle of the back ratio, supplementing the adjustment effect of the elastic failure of the back ratio.

[0029] A sliding structure 6 is provided at the connection portion between the lower end of the adjustment end 32 and the lower bundle 22. The sliding structure 6 is provided along the length direction of the lower bundle 22, so that the lower end of the adjustment end 32 can slide along the length direction of the lower bundle 22, thereby adjusting the lifting and tightening effect of the rear bundle 2. The sliding structure 6 is provided in the middle or near the middle of the binding structure 23. Specifically, the sliding structure 6 is provided between the lower ends of the first binding rib 231 and the second binding rib 232. Preferably, the sliding structure 6 is provided directly below the intersection of the first binding rib 231 and the second binding rib 232.

[0030] The sliding structure 6 includes a slide rail 61, which is embedded in the lower bundle 22, and an opening structure is set just above the lower bundle 22 corresponding to the slide rail 61, so as to facilitate the extension of the adjustment end 32 and prevent the adjustment end 32 from getting stuck when sliding. Correspondingly, a connecting sleeve 321 is set at the lower end of the adjustment end 32, and the connecting sleeve 321 is sleeved on the slide rail 61, so that the adjustment end 32 can slide along the slide rail 61 through the connecting sleeve 321.

[0031] As part of an embodiment of the utility model, further, the shoulder strap structure 4 includes a shoulder strap body and a plurality of adjustment blocks 42 arranged on the outer surface of the shoulder strap body, the adjustment blocks 42 protrude outward relative to the shoulder strap body, the plurality of adjustment blocks 42 are arranged at intervals, an adjustment ring 43 is installed on the shoulder strap body, and the adjustment ring 43 covers an adjustment block 42, when the shoulder strap structure 4 moves upward, the adjustment ring 43 is subjected to the pulling force of the adjustment part 3, and the position of the adjustment ring 43 relative to the human body remains basically unchanged, when the shoulder strap structure 4 moves upward to a certain position, the adjustment block 42 contacts the upper edge of the adjustment ring 43, preventing the shoulder strap structure 4 from continuing to move upward, thereby making the degree of tension of the adjustment ring on the adjustment part 3 unchanged, and will not cause the adjustment part 3 to loosen with the movement of the human body. When the shoulder strap structure 4 moves downward, the adjusting ring 43 is subjected to the pulling force of the adjusting part 3, and the position of the adjusting ring 43 relative to the human body remains basically unchanged. When the shoulder strap structure 4 moves downward to a certain position, the adjusting block 42 contacts the lower edge of the adjusting ring 43, preventing the shoulder strap structure 4 from continuing to move downward, thereby making the tightening degree of the adjusting ring on the adjusting part 3 unchanged. At the same time, when the bra is used for a long time and the back ratio 2 is loose, the adjusting ring can be removed and replaced to other adjusting block positions, thereby ensuring the adjustment effect of the adjusting part 3 on the back ratio. Among them, the material of the adjusting block 42 is set to at least one of fabric, metal material, plastic material, etc. The adjusting block 42 is fixedly connected to the shoulder strap body by sewing, welding, glue bonding, etc. The connected and fixed adjusting block and the shoulder strap body are an integrated structure to prevent the adjusting block from loosening. The material of the slide rail of the sliding structure 6 can be set to be the same as the material of the adjusting block 42.
