Technical Field

[0001] This utility model relates to the field of bra back clasp technology, and in particular to a bra back clasp that is easy to put on and take off. Background Technology

[0002] As people increasingly value the comfort and functionality of underwear, optimizing the structure of underwear accessories has gradually become a key focus of product development. As a crucial component for connecting and securing underwear, the design of the back clasp directly affects the ease of putting on and taking off the underwear and the overall experience. Traditional back clasps are usually located at the back of the underwear, requiring users to operate them from behind during the wearing process, which presents problems such as inconvenience and low efficiency, especially for people with limited arm mobility, making it more difficult to put on and take off the underwear.

[0003] Current bra back clasp technology typically uses a male-female snap structure or metal hook-and-loop assembly for connection, relying mainly on physical interlocking or hooking principles. The female snap is fixed to one side of the strap, and the male snap is inserted or hooked to complete the closure. Although the structure is stable, its position is still mostly at the back, often requiring the use of a mirror or assistance from others during wear. Furthermore, in actual use, because the back clasp assembly is located at the back, it is inconvenient to adjust and view, resulting in a poor user experience.

[0004] However, a common problem with existing technologies is that the back clasp structure of underwear is mostly located at the back, requiring the user to go around the body to put it on and take it off. This is inconvenient, time-consuming, and affects wearing efficiency, especially for the elderly or those with limited mobility who may not be able to use it independently. Therefore, there is an urgent need to provide a back clasp structure that is easier to operate and put on and take off, in order to improve wearing convenience and enhance the user experience.

[0037] Adjusting piece 1 and fixing piece 2 are used to connect and bind the underwear. Adjusting piece 1 and fixing piece 2 are fastened together by a detachable structure, making it easy to put on and take off.

[0038] Sub-plate 6 has a suture hole 8 inside, which provides a path for the stitches to pass through and enhances the stability of the suture. The outer wall of sub-plate 6 is provided with a suture thread 7, which passes through the suture hole 8 and fixes sub-plate 6 to the adjusting plate 1 to achieve reliable positioning of sub-plate 6 on the adjusting plate 1.

[0039] The mother plate 4 has a second suture hole 9 inside, which is used to improve the fixation stability of the mother plate 4; the outer wall of the mother plate 4 is provided with a first suture 5, which passes through the second suture hole 9 to fix the mother plate 4 to the fixing piece 2, so as to ensure a firm connection between the mother plate 4 and the fixing piece 2; the mother plate 4 has a stress hole 11 inside, which can cause the mother plate 4 to undergo local elastic deformation during the fastening process, thereby dispersing stress concentration, improving the displacement capacity during fastening, and enhancing the fastening stability and service life;

[0040] A connecting post 12 is fixedly connected to the top of the sub-plate 6 at its bottom, providing a mechanical connection structure with the mother plate 4. A connecting groove 13 is provided between the connecting post 12 and the sub-plate 6. The connecting groove 13 is used to engage with the internal partition structure of the mother plate 4 during the fitting process, playing a locking and limiting function to prevent loosening after fastening. An installation hole 10 is provided inside the mother plate 4, which is adapted to the connecting post 12. After the connecting post 12 is inserted into the installation hole 10, it engages with the internal structure of the mother plate 4 through the connecting groove 13, which is used to securely combine the mother plate 4 and the sub-plate 6, facilitating quick insertion and removal operations and improving connection reliability.

[0041] Reference Figure 1 and Figure 2Both the adjusting piece 1 and the fixing piece 2 are fixedly connected to an extension strip 14. The extension strip 14 is used to extend the length range of the adjusting piece 1 and the fixing piece 2, making it easier for users of different body types to wear and adapt, and improving wearing flexibility. The extension strip 14 is provided with a third suture 15, which is used to sew the extension strip 14 together to realize the structural connection and fixation of the extension strip 14, enhance the overall structural strength, and avoid stretching deformation. At the same time, the extension strip 14 and the adjusting piece 1 are fixed together by a second suture 7.

[0042] Both the adjustment piece 1 and the fixing piece 2 have a breathable layer 16 inside. The breathable layer 16 is used to improve air circulation in the back buckle area, reduce the increase in local skin temperature during wearing, and reduce the feeling of dampness and heat. A reinforcing layer 17 is fixedly connected to the top of the breathable layer 16. The reinforcing layer 17 is used to support the connection part during wearing and improve the deformation resistance of the back buckle structure. The breathable layer 16 is cuboid and 3mm thick. It is used to conform to the chest contour, enhance the fit and comfort of wearing, and reduce edge lifting or bulging. The reinforcing layer 17 is cuboid and 3mm thick. It is used to provide better support and prevent the buckle from falling off or tearing the fabric under tension, ensuring connection safety and usage stability.

[0043] A cover 3 is fixedly connected to the outer wall of the fixing piece 2.

[0044] Sub-plate 6 can be a metal sub-plate or a plastic sub-plate, and mother plate 4 can be a metal mother plate or a plastic mother plate. When sub-plate 6 is a metal sub-plate and mother plate 4 is a metal mother plate, the stability of the structural fit can be improved. When sub-plate 6 is a plastic sub-plate and mother plate 4 is a plastic mother plate, the hardness can be reduced and the user's comfort can be improved. Sub-plate 6 and mother plate 4 of appropriate materials can be selected and produced according to market demand. In this embodiment, sub-plate 6 is a plastic sub-plate and mother plate 4 is a plastic mother plate.

[0045] Working principle: When using this easy-to-wear bra back buckle, firstly, the main plate 4 and the fixing piece 2 are connected together by the first stitch 5 passing through the second stitch hole 9. When the adjusting piece 1 is connected to the sub-plate 6, the sub-plate 6 and the adjusting piece 1 are fixed together by the second stitch 7 passing through the first stitch hole 8. Then, when connecting, the connecting post 12 on the sub-plate 6 is pressed into the mounting hole 10 on the main plate 4, so that the inside of the main plate 4 is divided into multiple cards through the stress hole 11. Then, the cards are embedded in the connecting groove 13 for locking, thus achieving the effect of setting the back buckle at the front and making it easy to wear and take off.

[0046] The adjusting piece 1 and the fixing piece 2 are sewn together internally by stitch 15 and extension strip 14. Then, the extension strip 14 is folded into the adjusting piece 1 to hide the excess extension strip 14, making it a single structure. Subsequently, both the adjusting piece 1 and the fixing piece 2 are provided with a breathable layer 16 and a reinforcing layer 17. The reinforcing layer 17 is a high-strength woven fabric, which provides good support and prevents the fasteners from falling off or tearing the fabric. The breathable layer 16 is latex cotton, which has a certain degree of elasticity and helps to conform to the chest contour. Then, the fixing piece 2 is provided with a cover 3. When the adjusting piece 1 is fastened to the fixing piece 2, the adjusting piece 1 retracts into the cover 3, hiding the mother plate 4 and daughter plate 6 on the adjusting piece 1 and the fixing piece 2, so that the adjusting piece 1 and the fixing piece 2 form a whole, which improves comfort and hides the back buckle.
