[0036] Among them, the elastic decorative belt 30 is arranged on the outside of the waistband 20, and can be connected to the waistband 20 by sewing technology. The elastic decorative belt 30 not only provides elastic adjustment function within a certain size range of the waistband 20, but also plays a decorative role, making the bottom more beautiful. The elastic decorative belt 30 can be arranged in a circle position of the waistband 20 in a ring shape, or can be arranged in a part of the waistband 20 in a non-ring shape, which is not specifically limited here. The installation positions 22 are evenly distributed on both sides of the waistband 20 near the placket 21, and at least two installation positions 22 are provided on each side. The decorative fastener 40 can cooperate with different installation positions 22 to adjust the tightness of the waistband 20. By selecting different installation positions 22, the waist circumference can be further adjusted to ensure the comfort of the wearer.

[0037] In this embodiment, a plurality of mounting positions 22 are respectively provided on both sides of the waistband 20 near the placket 21, and the tightness adjustment structure includes a primary adjustment component and a secondary adjustment component. The primary adjustment component includes an elastic decorative belt 30 arranged along the length direction of the waistband 20, and the elastic decorative belt 30 is integrally connected with the waistband 20, providing basic tightness adjustment, making the bottoms more convenient and comfortable to wear, and improving the aesthetics of the bottoms.

For example, when the waistband 20 needs to be tightened, the slot 221 with a larger interval can be selected; conversely, when the waistband 20 needs to be loosened, the slot 221 with a smaller interval can be selected. It should be further explained that the two hooks 411 are respectively arranged at non-edge positions at both ends of the inner side of the decorative fastener 40, that is, reserved spaces are provided between the two hooks 411 and the two side edges of the decorative fastener 40. When it is necessary to loosen the waistband 20 and select the slots 221 with smaller intervals, the reserved space can cover the unused slots 221 next to it, thereby ensuring the aesthetics of the lower garment.

[0040] In some optional embodiments, the elastic decorative band 30 is arranged in a ring shape at a position of the waistband 20, and the slot 221 includes an opening 2211 and a body 2212 connected to the opening 2211. The openings 2211 of the slot 221 are arranged on both sides of the elastic decorative band 30 near the placket 21, and the body 2212 of the slot 221 is formed between the elastic decorative band 30 and the waistband 20. The hook 411 can be inserted into the opening 2211 from top to bottom and then stored in the body 2212. In this embodiment, the hook 411 can be inserted into the opening 2211 from top to bottom and then stored in the body 2212, which not only ensures the stability of the hook 411, but also makes it hidden inside the waistband 20, so that it does not directly touch the wearer's skin, avoiding discomfort when wearing.

[0041] In some optional embodiments, the elastic decorative belt 30 is non-circular and is only arranged at a part of the waistband 20 away from the placket 21. The slot 221 includes an opening 2211 and a body 2212 connected to the opening 2211. The openings 2211 of the slot 221 are arranged on both sides of the waistband 20 where the elastic decorative belt 30 is not arranged and close to the placket 21; the position where the opening 2211 is arranged on the waistband 20 is provided with an isolation layer, and the body 2212 of the slot 221 is formed between the waistband 20 and the isolation layer. The hook 411 can be stored in the body 2212 after being inserted into the opening 2211 from top to bottom. The isolation layer can be connected to the inner side of the waistband 20 by sewing technology, and a softer and more comfortable fabric can be selected. In this embodiment, the isolation layer is arranged, so that the hook 411 is covered by the isolation layer after being inserted into the opening 2211, and will not directly contact the wearer's skin, so that friction or pressure can be avoided and the wearing comfort can be improved.

[0042] In some optional embodiments, the elastic decorative band 30 is non-annular and is only arranged at a portion of the waistband 20 away from the placket 21, and the slot 221 includes an opening 2211 and a body 2212 connected to the opening 2211. The waistband 20 includes an outer layer and an inner layer, the opening 2211 is arranged in the outer layer, the body 2212 of the slot 221 is formed between the outer layer and the inner layer, and the hook 411 can be stored in the body 2212 after being inserted into the opening 2211 from top to bottom, so that the hook 411 is covered by the inner layer after being inserted into the opening 2211 and does not directly contact the wearer's skin.

[0043] Please refer to the attached Figure 6 and attached Figure 7 In some optional embodiments, the hook 411 includes a connecting end, an inserting end, and a body 2212 section connected between the connecting end and the inserting end. The connecting end is fixedly connected to the decorative fastener 40, and the inserting end is provided with a locking portion 4115. When the locking portion 4115 is inserted from top to bottom into the bottom end of the slot 221, it abuts against the side wall of the bottom end of the slot 221 to prevent the hook 411 from slipping off. Among them, the locking portion 4115 adopts a rounded design to avoid sharp edges to prevent damage to clothing or skin. Specifically, the locking portion 4115 can be bent from the insertion end in a direction away from the decorative fastener 40 to form a rounded ring, or it can be expanded outward along the circumference of the body 2212 section to form a rounded sphere.

[0044] In some optional embodiments, the body 2212 includes a first section 4113 arranged perpendicularly to the side of the decorative fastener 40 and a second section 4114 arranged parallel to the side of the decorative fastener 40, the connecting end is connected to the first section 4113, and the inserting end is connected to the second section 4114. The length of the first section 4113 should not be too long, so that after the hook 411 is inserted into the slot 221, the side of the decorative fastener 40 where the hook 411 is arranged is as close as possible to the outside of the elastic decorative band 30 or the waistband 20, so as to maintain the overall flatness and beauty. The length of the second section 4114 is greater than the length of the first section 4113, and the length of the second section 4114 is adapted to the depth of the slot 221, so that after the second section 4114 is inserted into the slot 221, it can be completely hidden inside the body 2212 as much as possible to avoid being exposed, thereby improving the beauty and use stability of the decorative fastener 40.

[0045] In some optional embodiments, the end of the second section 4114 away from the insertion end is expanded along the circumference of the second section 4114 to form another locking portion 4115, so that when the second section 4114 is fully inserted into the slot 221, the locking portion 4115 can abut against the opening 2211 of the slot 221, further enhancing the connection stability between the hook 411 and the slot 221, and preventing the hook 411 from accidentally slipping out.

[0046] It should be further explained that the width of the middle part of the second section 4114 is greater than the width of the two end parts, forming a structure with a wide middle part and narrow ends; wherein, the structure with a wide middle part and narrow ends not only saves effort during the insertion process of the hook 411, but also provides stronger connection stability after the hook 411 is fully combined with the slot 221. Specifically, since the two ends of the hook 411 are narrower, the force required for the hook 411 to be inserted into the slot 221 will be smaller, which reduces the friction resistance between the hook 411 and the slot 221, reduces the difficulty of insertion, and enables the user to insert the hook 411 into the slot 221 more easily. The middle part of the hook 411 is wider, and when the hook 411 is fully inserted into the slot 221, the middle wide part will fit tightly against the inner wall of the slot 221, thereby increasing the friction between the hook 411 and the slot 221, which can effectively prevent the hook 411 from loosening or falling off during use, and ensure the stability of the connection.

[0047] Please refer to the attached Figure 8In some optional embodiments, the width of the middle part of the slot 221 is greater than the width of the two end parts, forming a structure that is wide in the middle and narrow at both ends. This structural design cooperates with the aforementioned plug hook 411 that is wide in the middle and narrow at both ends, so that the plug hook 411 can enter the slot 221 more easily when inserted, and obtain a tighter connection when inserted into the middle part. Among them, the middle wide part of the slot 221 fits tightly with the middle wide part of the plug hook 411, which increases the friction and contact area, thereby effectively improving the connection stability. The width of the narrow parts at both ends of the slot 221 is slightly greater than the width of the narrow parts at both ends of the plug hook 411, so that the plug hook 411 is easier to insert into the slot 221.

[0048] In some optional embodiments, the width of the upper end of the slot 221 is greater than the width of the lower end, forming a structure with a wide upper end and a narrow lower end; wherein the design of the wide upper end makes it easier for the hook 411 to align and insert into the slot 221, reducing the difficulty of insertion. When the hook 411 is gradually inserted into the slot 221, the narrow part of the lower end provides a gradually increasing friction force, and finally a firm connection is achieved at the narrow part of the lower end of the slot 221, so that when the hook 411 completely enters the slot 221, a firm lock is achieved to prevent the hook 411 from loosening or falling off.

[0049] In some optional embodiments, the decorative fastener 40 and the plug hook 411 are an integrally formed structure, which is easy to manufacture, has enhanced strength and improved aesthetics. Furthermore, the decorative fastener 40 and the plug hook 411 can be made of materials with high strength and relatively good durability. Specifically, the decorative fastener 40 and the plug hook 411 are made of metal materials or high-strength plastic materials to ensure their durability and stability in daily use. Among them, the metal material can be stainless steel, aluminum alloy, etc.; the high-strength plastic material can be reinforced polypropylene.

[0050] In some optional embodiments, not only the elastic function of the elastic decorative belt 30 should be considered, but also it is necessary to ensure that it has a certain stiffness to improve the texture of the bottoms (such as pants, skirts, etc.), which can be selected from one of the following: elastic leather belt, high-density elastic webbing, polyurethane coated elastic belt. Among them, the elastic leather belt can be made of natural or synthetic leather, and elastic materials are usually added inside to provide elastic function, and the leather itself has a certain stiffness. High-density elastic fabric can be made of spandex fiber and other fiber blended weaving, with excellent elasticity and a certain stiffness. The polyurethane coated elastic belt can be formed by coating a polyurethane coating agent on the surface of the elastic belt.

[0051] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
