Description

Memory reset back buckle and underwear Technical Field The utility model relates to the field of bra accessories, in particular to a memory reset back buckle and underwear. Background In the field of bra accessories, the back button is a key component for connecting the front and back fabric of the bra, and the performance and comfort of the back button are directly related to the experience of a wearer. Traditional back buckles are often limited by overall size and material selection, resulting in back buckles that do not achieve accurate repositioning after telescoping during wear. This problem makes the wearer feel a remarkable binding feeling and a sense of urgency when wearing the bra for a long time, and affects the comfort and freedom of wearing. Specifically, conventional back buckles are generally made of rigid materials, and are structurally fixed and do not have elastic expansion and contraction capability. Therefore, when the tightness of the bra needs to be adjusted during wear, the back buckle often cannot adapt to the change, which causes discomfort to the wearer. In addition, due to the material and structural design limitations of the traditional back button, the durability of the traditional back button is relatively poor, and the traditional back button is easy to damage or deform in the use process, so that the wearing comfort and the service life of the bra are further influenced. In order to solve the above problems, some improved back buckle designs are presented in the market. However, most of these designs are only fine-tuned in appearance or material, and the problem that the back buckle cannot be accurately reset after being stretched is not fundamentally solved. Thus, these improved back fasteners still present a large lifting space in terms of wearing comfort and durability. Disclosure of utility model The utility model aims to overcome the defects that the common back buckle in the prior art cannot be accurately reset after being stretched and the internal structure of the back buckle is loose and is inconvenient for a user to use, is limited by the whole size or materials and is worn to feel the constraint and pressing sense. The technical scheme adopted by the utility model is that the memory reset back buckle comprises a hook part and a ring part, wherein the hook part and the ring part are mutually buckled to realize connection, the ring part comprises a base layer and a plurality of rows of buckles arranged on the base layer, the base layer comprises an elastic base layer and a surface layer from inside to outside, the buckles are sewn and fixed on the elastic base layer, the surface layer is coated with the elastic base layer, and part of buckles are exposed. The hook part and the ring part are connecting parts of the back buckle, the connecting parts are mutually buckled to fix the bra, the elastic base layer is arranged on the inner layer of the base layer, longitudinal and transverse stretching performance is provided for the whole back buckle, and the back buckle can automatically and accurately reset after stretching, so that the original specification and the size of the back buckle are always kept, and the problem of unstable size caused by continuous stretching deformation of the traditional back buckle is solved. Meanwhile, the retaining ring is sewn on the elastic base layer, so that the retaining ring can be stably fixed on the base layer, thread off or breakage caused by repeated stretching is avoided, and the stability of the whole structure of the back buckle is maintained. The surface layer is an outer layer coating the elastic base layer and is also a contact layer of skin, so that not only is the inner sewing thread hidden and protected, but also foreign body sensation during skin contact is reduced, good touch feeling is provided for the skin, meanwhile, softness of the surface layer is cooperated with elasticity of the base layer, unbound wearing experience is provided, and wearing comfort is increased. Further, the elastic base layer is of a three-layer structure and comprises a middle layer made of memory reset glue and a double-stretching layer which is thermally fixed on the front side and the back side of the memory reset glue layer. The memory reset rubber material layer can automatically and accurately reset after stretching when the back buckle is endowed with longitudinal and transverse stretching capability due to the elastic characteristics of the memory reset rubber material layer, so that the back buckle can be restored to the original shape after the bra is taken off, and the durability and the stability of the back buckle are maintained. The double-layer cloth has two-way stretchability, and can further cooperate with the elasticity of the memory reset adhesive layer to provide additional support and stability. Further, the memory reset glue layer is a reticular structure, each unit of the reticular structure is a rectangular unit, the lo
