Description

Technical Field

[0001] This application relates to the field of underwear adjustment structure technology, and in particular to an ultrasonic heat-pressed sports bra with an adjustable back buckle and adjustable back strap. Background Technology

[0002] Underwear, swimwear, and other intimate apparel are indispensable in daily life, serving not only aesthetic purposes but also providing comfort and functional support. As consumers' demands for a superior wearing experience continue to rise, underwear design is constantly evolving. In recent years, designers have focused on developing more invisible and comfortable back clasp designs to meet the needs of different body types and usage scenarios. These designs typically prioritize aesthetics and ease of wear, striving to enhance functionality without compromising visual appeal.

[0003] Currently, most bra back clasps on the market use metal hook-and-loop fasteners. While these are simple in structure and inexpensive, they are prone to rusting and deformation, and may loosen after repeated use. This makes them unsuitable for swimwear or sports bras, which are typically worn for physical activity. Furthermore, because multiple back clasps are usually required to ensure a secure hold, users often struggle to find the correct fastener position when putting on or taking off the bra. This results in inaccurate positioning and complex operation, making the fastening and adjustment process cumbersome and inconvenient for users. Utility Model Content

[0004] The purpose of this application is to provide an ultrasonic heat-pressing sports bra with an adjustable back buckle and adjustable back strap, so as to achieve quick positioning and convenient fastening of the back buckle.

[0005] Firstly, the ultrasonic heat-pressing sports bra adjustable back clasp provided in this application adopts the following technical solution:

[0006] An adjustable back clasp for an ultrasonic heat-pressed sports bra includes a clasp assembly and several clasp hole assemblies. The clasp assembly includes a clasp body, and the clasp hole assembly includes a clasp hole body adapted to the clasp body.

[0007] The buckle body is snapped into the buckle hole body so that the buckle assembly and the buckle hole assembly are fastened together.

[0008] By adopting the above technical solution, the snap-fit ​​design between the snap body and the snap hole body of this application allows users to easily align and fasten the snap body component and the snap hole component when putting on and taking off underwear, without having to try multiple times to complete the fastening operation, which greatly improves the convenience of use and user experience. It enables the quick positioning and convenient fastening of the back snap of the underwear. At the same time, this structure also ensures the stability after fastening and avoids safety hazards caused by loose fastening.

[0009] Furthermore, a limiting plate is provided on one side of the top of the buckle hole body, and a limiting block is provided inside the buckle hole body, with the limiting block located below the limiting plate;

[0010] The buckle body is engaged between the limiting block and the limiting plate, so that the buckle assembly and the buckle hole assembly are engaged with each other.

[0011] By adopting the above technical solution, the design of the limiting plate and limiting block in this application can effectively prevent the buckle body from moving within the buckle hole body, improving the stability and reliability after fastening. At the same time, the cooperation between the limiting plate and the limiting block allows the buckle body to be more precisely engaged within the buckle hole body, simplifying the user's operation steps and improving ease of use.

[0012] Furthermore, the buckle body is provided with a clearance groove at the engagement point with the limiting block and the limiting plate, and the width of the clearance groove is greater than the width of the limiting block.

[0013] By adopting the above technical solution, the recessed groove of this application allows the buckle body to smoothly engage between the limiting block and the limiting plate, avoiding the problem of engagement difficulties caused by the large width of the limiting block, and improving the convenience and reliability of the fastening. At the same time, the design that the width of the recessed groove is greater than the width of the limiting block further enhances the stability of the fastening, preventing the buckle body from loosening or falling off due to external forces during use, and improving the user's wearing experience.

[0014] Furthermore, the top of the limiting plate is provided with a protrusion, and the middle of the buckle body is provided with a hollow part.

[0015] By adopting the above technical solution, the protrusion on the top of the limiting plate of this application allows the user to determine the front and back of the buckle body by touch even when the back buckle is not visible.

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application provides a clear and complete description of the technical solutions. The described embodiments are merely possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can, in conjunction with the embodiments of the present invention, obtain other embodiments without creative effort, and these embodiments are also within the protection scope of the present invention.

[0042] The inventors of this application have discovered that existing bra back clasps, in order to be more concealed, typically have smaller back clasps and require multiple clasps to be fastened to ensure the strength of the clasp. However, users often find it difficult to position the back clasps when putting on and taking off bras, making the fastening process cumbersome and inconvenient. Therefore, this application provides an ultrasonic heat-pressing adjustable back clasp for sports bras, referring to... Figure 1 and Figure 2 The device includes a buckle assembly 1 and several buckle hole assemblies 2. The buckle assembly 1 includes a buckle body 11, and the buckle hole assembly 2 includes a buckle hole body 21 that is adapted to the buckle body 11. The buckle body 11 snaps into the buckle hole body 21, allowing the buckle assembly 1 and the buckle hole assembly 2 to engage with each other, thus simplifying the fastening process and improving the user experience. In practical implementation, both the buckle assembly 1 and the buckle hole assembly 2 can be made of high-strength plastic, possessing good durability and resistance to deformation.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a limiting plate 22 is provided on one side of the top of the buckle hole body 21, and a limiting block 23 is provided on the inner side of the buckle hole body 21, with the limiting block 23 located below the limiting plate 22. The buckle body 11 is engaged between the limiting block 23 and the limiting plate 22, so that the buckle body 11 and the buckle hole body 21 are tightly fitted, thereby enabling the buckle assembly 1 and the buckle hole assembly 2 to fasten together. In specific implementation, the limiting block 23 can be a straight structure, and the limiting plate 22 can be a horizontal beam, with both forming a stable clamping space. This design not only prevents the buckle body 11 from slipping out, but also reduces the influence of external factors on the fastening.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment of the application, the snap fastener body 11 has a relief groove 111 at the engagement point with the limiting block 23 and the limiting plate 22. The width of the relief groove 111 is greater than the width of the limiting block 23. Thus, when the snap fastener body 11 is engaged with the snap hole body 21, the relief groove 111 can accommodate a portion of the limiting block 23, reducing the pressure on the engagement point and extending its service life. In specific implementations, the relief groove 111 can be a straight groove, and its width can be adjusted according to actual needs.

[0045] like Figure 1 , Figure 3 and Figure 5 As shown, the limiting plate 22 of this embodiment has a protrusion 221 on its top and a hollow portion 112 in the middle of the buckle body 11. The protrusion 221 can guide the buckle body 11 when it is inserted into the buckle hole body 21, ensuring that the buckle body 11 accurately enters the predetermined position. The hollow portion 112 can increase the flexibility of the buckle body 11, making it easier to bend and stretch, and facilitating user operation. For example, the protrusion 221 can be a small circular or polygonal protrusion, and the hollow portion 112 can be a rectangular or elliptical opening.

[0046] like Figure 3 and Figure 5 As shown, for ease of installation and disassembly, the snap hole assembly 2 of this embodiment further includes a snap hole mounting block 24, with the snap hole body 21 formed in the middle of the snap hole mounting block 24. The snap body assembly 1 also includes a snap body mounting block 12, with the snap body body 11 fixed to one side of the bottom surface of the snap body mounting block 12. Both the snap body mounting block 12 and the snap hole mounting block 24 are made of soft, elastic material to facilitate fixing them to clothing by ultrasonic heat pressing.

[0047] like Figure 5 and Figure 6 As shown, to further enhance the fixing effect, the upper surface of the buckle mounting block 12 in this embodiment has two connecting grooves 121. These two connecting grooves 121 are located at both ends of the buckle body 11, facilitating the connection of the buckle mounting block 12 and the underwear body material via ultrasonic hot pressing. The lower surface of the buckle mounting block 12 is also provided with two anti-slip blocks 122, which are also located at both ends of the buckle body 11. The design of the connecting grooves 121 and the anti-slip blocks 122 not only enhances the stability of the buckle mounting block 12 but also facilitates its connection with other components. For example, the connecting grooves 121 can be elongated, and the anti-slip blocks 122 can be rubber or other materials with a high coefficient of friction.

[0048] like Figure 6 As shown, in this embodiment of the application, the side wall at the connection between the buckle body 11 and the buckle mounting block 12 is provided with several fixing posts 113. These fixing posts 113 contact the inner wall of the buckle hole body 21, making the buckle body 11 more firmly snapped into the buckle hole body 21. In specific implementation, the fixing posts 113 can be cylindrical, which ensures the stability of the buckle body 11 without affecting its flexibility.

[0049] The implementation principle of this embodiment is as follows: The ultrasonic heat-pressing sports bra back clasp of this application embodiment not only achieves fast and accurate fastening, but also greatly improves the user's wearing comfort. Especially for the elderly or people with poor hand dexterity, this design greatly reduces the difficulty of putting on and taking off clothing, improves the overall user experience, and enables quick positioning and convenient fastening of the bra back clasp. At the same time, this structure also ensures the stability after fastening, avoiding safety hazards caused by loose fastening.

[0050] This application also provides an ultrasonic heat-pressing sports bra adjustable back strap, see reference. Figure 1 and Figure 2 This invention includes an ultrasonic heat-pressed adjustable back clasp for a sports bra, and also includes a clasp mounting fabric 3 for mounting the clasp assembly 1 and a clasp hole mounting fabric 4 for mounting three clasp hole assemblies 2. The clasp assembly 1 is inserted into any of the clasp hole assemblies 2, connecting the clasp mounting fabric 3 and the clasp hole mounting fabric 4, achieving a simple and quick adjustment effect and improving wearing comfort. In specific implementation, the clasp hole assemblies 2 and the clasp assembly 1 are mounted on the clasp hole mounting fabric 4 and the clasp mounting fabric 3 using ultrasonic heat pressing.

[0051] like Figure 1 and Figure 2As shown, the fastener mounting fabric 3 of this embodiment includes a first outer layer 31 and a first inner layer 32 from the outside to the inside. These two layers can be tightly bonded together using ultrasonic hot pressing technology to form a sturdy whole. The fastener assembly 1 is installed between the first outer layer 31 and the first inner layer 32, and is located at the edge of the fastener mounting fabric 3 near the fastener hole mounting fabric 4. Specifically, one side of the fastener mounting block 12 is fixed between the first outer layer 31 and the first inner layer 32 using ultrasonic hot pressing technology. This layout not only saves space but also facilitates user operation. In specific implementation, the first outer layer 31 can be made of cotton fabric, which is soft and comfortable to the touch and suitable for long-term close-fitting wear; the first inner layer 32 can be made of breathable mesh fabric, which helps to wick away sweat and dissipate heat, keeping the wearer dry.

[0052] like Figure 1 and Figure 2 As shown, the snap-hole mounting fabric 4 in this embodiment includes a second outer layer 41 and a second inner layer 42 from the outside to the inside. These two layers are also tightly bonded together using ultrasonic hot-pressing technology. Three snap-hole components 2 are installed between the second outer layer 41 and the second inner layer 42, and are arranged sequentially at fixed intervals. Specifically, the perimeter of the snap-hole mounting block is fixed between the second outer layer 41 and the second inner layer 42 using ultrasonic hot-pressing technology. This design makes it more intuitive and convenient for users to adjust the size. For example, the second outer layer 41 can be a silk fabric with good luster and a beautiful appearance; the second inner layer 42 can be an antibacterial and odor-resistant fabric, which helps maintain hygiene.

[0053] In a preferred embodiment, to improve overall stability and comfort, the edges of both the fastener mounting fabric 3 and the buttonhole mounting fabric 4 are reinforced. For example, a reinforcing strip approximately 1 cm wide can be added around the edges to prevent cracking, increase thickness, and improve the feel. The reinforcing strip can be made of elastic fiber material, which maintains softness while providing some support.

[0054] Furthermore, the connection methods between the fastener mounting fabric 3 and the fastener hole mounting fabric 4 are also very flexible and diverse. In addition to the basic plug-in connection, some auxiliary fixing measures can be added. For example, Velcro or buttons can be installed at the connection between the fastener mounting fabric 3 and the fastener hole mounting fabric 4, so that they will not easily come loose even during vigorous exercise. Velcro can be selected with strong double-sided adhesion to ensure a firm and reliable hold; buttons can be made of metal, which is durable and easy to clean.

[0055] To accommodate users of different body types, the length and width of both the fastener mounting fabric 3 and the buttonhole mounting fabric 4 can be adjusted appropriately. For example, various specifications can be provided for users to choose from, or a certain margin can be reserved in the design to allow users to cut or splice them themselves. This not only better meets personalized needs but also expands the product's applicability.

[0056] The implementation principle of this embodiment is as follows: by integrating the adjustable back buckle of the ultrasonic heat-pressed sports bra into the back strap, the adjustable back strap of this invention not only possesses the basic functions of a traditional back strap, but also significantly improves in terms of adjustment convenience and comfort. Especially during sports activities, users can easily adjust the tightness of the back strap according to their own needs at any time, avoiding discomfort caused by improper size. In addition, the application of ultrasonic welding technology and multi-layer composite materials makes the entire back strap lighter and more durable, meeting the modern consumer's pursuit of high-quality underwear.

[0057] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
