Technical Field
[0001] This utility model relates to the field of freely replaceable bra technology, specifically a novel freely replaceable back bra. Background Technology
[0002] With the accelerating pace of modern life and people's pursuit of quality of life, women have increasingly higher requirements for the comfort and convenience of bras. Consumers' demand for personalized bras is growing, with more requirements not only for style, color, and pattern, but also for more choices and customization in function and structure. Various new adjustment structures are constantly emerging, such as rotating buckles, Velcro, and zippers. These adjustment structures not only make it easy to adjust the tightness of the bra, but also improve the bra's appearance and durability. Furthermore, advanced manufacturing processes, such as hot pressing and seamless processes, make the bra more refined and beautiful, while also improving the bra's quality and comfort.
[0003] In the current technology, most traditional bras that cannot be freely changed at the back are back-fastening designs. During daily wear, if the bra feels too tight or too loose after wearing it for a period of time, it is relatively troublesome to adjust it because the back structure cannot be freely changed. In addition, when matching different clothes, it is impossible to change the style of the bra back according to the requirements of the clothes, which may lead to the bra and clothing not matching, affecting the overall aesthetics. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a new type of bra with freely replaceable back, in order to solve the technical problem that traditional bras, which cannot be freely replaced at the back, are mostly back-fastening designs. In daily wear, if the bra feels too tight or too loose after wearing it for a period of time, it is relatively troublesome to adjust it because the back structure cannot be freely replaced. Furthermore, when matching different clothes, it is impossible to change the style of the bra's back according to the requirements of the clothing, which may lead to the bra and clothing not matching, affecting the overall aesthetics.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel backless interchangeable bra, comprising two sets of cups, each set of cups being fixedly connected on one side by a strap, and each set of cups being fixedly connected to a bandage on one side, wherein one set of bandages is movably connected to a first back strap on one side, and the other set of bandages is movably connected to a second back strap on one side, wherein one side of the first back strap is movably connected to one side of the second back strap.
[0006] By adopting the above technical solution, the connecting buckles, which are fixedly connected to the connecting fabric inside the cavity, are movably connected to the first back strap, and the connecting buckles, which are fixedly connected to the connecting fabric, are movably connected to the second back strap. The connecting buckles are locked by an elastic plate, which achieves the function of freely changing the back of the bra. This allows the bra back to be matched with the style of the clothing and to be easily changed when the shoulder straps or underbust are too tight or too loose.
[0007] Furthermore, each set of cups is fixedly connected to a shoulder strap at the top, each set of shoulder straps is fixedly connected to a buckle at the bottom, the band is fixedly connected to an ear, and the first back strap and the second back strap are both fixedly connected to two sets of ear.
[0008] By adopting the above technical solution, the shoulder straps are fixedly connected to the back of the bra via a connecting buckle, thereby fixing the two sets of cups to the back and achieving the effect of freely changing the back. At the same time, because women's body structures are different, the shoulder straps of traditional bras are prone to slipping. By adding multiple sets of tabs, women can freely adjust the bra according to their own body shape.
[0009] Furthermore, each set of the aprons is movably connected to one side with a connecting buckle, each set of the connecting buckles is fixedly connected to one side with a connecting cloth, and each set of the connecting buckles is fixedly connected to the bottom with an elastic plate.
[0010] By adopting the above technical solution, the two sets of welts and the two sets of connecting fabrics can be movably connected by the connecting buckle. After the connecting fabric is connected to the welt, the connecting buckle is locked by rotating the elastic plate to prevent it from falling off during use.
[0011] Furthermore, one side of one set of the connecting fabric is fixedly connected to the inside of the first back strap, and one side of the other set of the connecting fabric is fixedly connected to the inside of the second back strap. Both the first back strap and the second back strap have cavities on one side for connecting with the connecting fabric.
[0012] By adopting the above technical solution, two sets of connecting fabrics are fixedly connected to the first back strap and the second back strap respectively, and the connecting fabrics are connected through the cavity.
[0013] Furthermore, three sets of hooks are fixedly connected to one side of the first back strap, and three sets of grooves are fixedly connected to one side of the second back strap.
[0014] By adopting the above technical solution, the first back strap and the second back strap are movably connected by three sets of hooks and three sets of grooves, and the back strap distance can be adjusted by grooves at different distances.
[0015] Furthermore, the top of both the first and second back straps is provided with an insertion hole for connection with a fastening buckle, and a silicone pad is fixedly connected inside each set of cups.
[0016] By adopting the above technical solution, the shoulder strap is connected to the first back strap and the second back strap through the insertion hole, and the silicone pad prevents the skin from rubbing against the fabric.
[0017] In summary, the present invention has the following advantages: The present invention uses connecting buckles with connecting cloth fixedly connected inside the cavity to movably connect with the first back strap, and connecting buckles with connecting cloth fixedly connected with the second back strap, and the connecting buckles are locked by an elastic plate, so as to achieve the function of freely changing the back of the bra. This achieves the effect of matching the style of the bra back according to the requirements of the clothing and conveniently changing the bra back when the shoulder straps or underbust are too tight or too loose.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] A new type of backless interchangeable bra, such as Figure 1-7 As shown, it includes two sets of bra cups 1. Both sets of bra cups 1 are fixedly connected on one side by a strap 2. Each set of bra cups 1 is fixedly connected to one side by a band 3. Each set of band 3 is movably connected to one side by a connecting buckle 8. Each set of connecting buckles 8 is fixedly connected to one side by a connecting fabric 7. One side of one set of connecting fabric 7 is fixedly connected to the inside of the first back strap 5, and the other side of one set of connecting fabric 7 is fixedly connected to the inside of the second back strap 10. Both the first back strap 5 and the second back strap 10 have cavities 6 on one side to connect with the connecting fabric 7. The two sets of connecting fabric 7 are fixedly connected to the first back strap 5 and the second back strap 10 respectively, and the connecting fabric 7 is connected through the cavities 6.
[0029] Each set of connecting buckles 8 has an elastic plate 9 fixedly connected to its bottom. The two sets of webbing 3 and the two sets of connecting cloth 7 are movably connected through the connecting buckles 8. After the connecting cloth 7 is connected to the webbing 3, the connecting buckle 8 is locked by rotating the elastic plate 9 to prevent it from falling off during use.
[0030] One set of bandages 3 is movably connected to the first back strap 5 on one side, and the other set of bandages 3 is movably connected to the second back strap 10 on one side. The top of the first back strap 5 and the second back strap 10 are both provided with insertion holes 13 for connecting with the fixing buckle 4. Each cup 1 is fixedly connected to a silicone pad 14. The shoulder strap 15 is connected to the first back strap 5 and the second back strap 10 through the insertion holes 13, and the silicone pad 14 prevents the skin from rubbing against the fabric. At the same time, due to different body structures, the shoulder straps of traditional bras are prone to slipping. Therefore, multiple sets of loops 16 are added to one end of the bandages 3, the first back strap 5 and the second back strap 10, so that women can adjust the effect freely according to their own body.
[0031] The first back strap 5 is movably connected to the second back strap 10 on one side. Three sets of hooks 12 are fixedly connected to one side of the first back strap 5, and three sets of grooves 11 are fixedly connected to one side of the second back strap 10. The first back strap 5 and the second back strap 10 are movably connected through the three sets of hooks 12 and the three sets of grooves 11, and the distance of the back straps can be adjusted through the grooves 11 at different distances.
[0032] Please see Figure 4 Each set of cups 1 is fixedly connected to the top of a shoulder strap 15, and each set of shoulder straps 15 is fixedly connected to the bottom of a buckle 4. By setting the above structure, the shoulder straps 15 are fixedly connected to the back of the bra through the buckle 8, thereby fixing the two sets of cups 1 to the back and achieving the effect of freely changing the back.
[0033] The working principle of this utility model is as follows: When in use, the user sews the two sets of cups 1 together with needle and thread by pulling the strap 2, and then fixes the two sets of shoulder straps 15 together with thread. Each set of shoulder straps 15 is fixedly connected with a fixing buckle 4 at the end. Finally, the two sets of silicone pads 14 are fixed to one side inside the cup 1 to prevent the user's skin from rubbing against the cup 1 and getting injured during use.
[0034] After the main body of the bra is connected, the back of the bra can be freely changed. After selecting the back to be connected, find the cavity 6 opened on one side of the first back strap 5 and the second back strap 10. Each cavity 6 is fixedly connected with a connecting cloth 7. Each connecting cloth 7 is fixedly connected to a connecting buckle 8 through a connecting hole on one side. Then, pull open one side of the first back strap 5 to expose the connecting buckle 8. Pass the elastic plate 9 fixedly connected to the bottom of the connecting buckle 8 through the connecting hole of the band 3. Manually rotate the elastic plate 9 to a position flush with the band 3 to connect the back to the main body of the bra. At the same time, due to different body structures, the shoulder straps of traditional bras are prone to slipping. Therefore, multiple sets of ear loops 16 are added to one end of the band 3, the first back strap 5 and the second back strap 10 to allow women to adjust the effect freely according to their own body.
[0035] After the first back strap 5 is connected to one of the band straps 3, the second back strap 10 is connected to the band strap 3 through the same steps. When the user needs to use the bra, the two shoulder straps 15 are fixed to it through the insertion holes 13 opened in both the first back strap 5 and the second back strap 10, and the entire bra is connected through the hook 12 fixedly connected to one side of the first back strap 5 and the groove 11 fixedly connected to one side of the second back strap 10.
