本申请要求于2022年11月17日提交中国专利局，申请号为202211440908.5，名称为“一种钩扣结构及内衣背扣”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及内衣配件技术领域，特别涉及一种钩扣结构及内衣背扣。
背景技术
传统的钩扣结构，扣眼多为平面结构，部分为阶梯面折弯形成且只有单个定位环；传统的钩件多为平直折弯，部分钩头嵌设于定位环内圈，没有设置安全卡点，而且只有单个定位环。上述传统的钩扣结构都是贴近内衣背扣的布层，导致触压面大，增大了对皮肤的压迫感；另外折弯成型结构通常折弯处因受力容易变形甚至折断，影响整件内衣的使用寿命。
发明内容
为了克服现有技术存在的缺陷，本发明提供一种钩扣结构及内衣背扣。
本发明解决其技术问题所采用的技术方案是：一种钩扣结构，包括：
扣眼，其一端设有定位环，另一端设有台阶扣位；
钩件，其一端设有定位环，另一端设有钩部；
所述台阶扣位向远离扣眼的定位环底面方向凸出，钩件通过钩部扣合在台阶扣位上，从而与扣眼扣合。
作为优选，所述台阶扣位包括平扣段和斜延段，平扣段与扣眼的定位环相互平行，平扣段通过斜延段与扣眼的定位环相连，平扣段位于扣眼的定位环远离底面的一侧，钩部扣合在平扣段上。
作为优选，所述扣眼两侧分别设有一组定位环，扣眼由整条料条一体弯折成型。
作为优选，所述钩件的定位环与钩部间形成有扣合开口，钩件的定位环面向钩部一侧设有安全卡点。
作为优选，所述安全卡点的顶部形成有弧形凸起，两侧分别与钩件的定 位环和钩部形成有弧形平滑过度。
作为优选，所述钩部前端设有向远离扣合开口方向翘起的翘曲部。
作为优选，所述钩部前端向安全卡点方向弯折，翘曲部的后端与安全卡点在扣合开口中形成狭窄段，翘曲部的前端与钩件的定位环在扣合开口处形成外扩导向段。
作为优选，所述钩件两侧分别设有一组定位环，钩件由整条料条一体弯折成型。
一种内衣背扣，包括第一连接带、第二连接带，以及上述的钩扣结构，所述扣眼设置在第一连接带上，钩件设置在第二连接带上。
作为优选，所述扣眼沿第一连接带长度方向阵列设有多排，扣眼通过定位环配合车缝固定在第一连接带上，其中，第一连接带由多层布料构成，扣眼的定位环包覆在布料中，台阶扣位穿出到第一连接带外侧，第一连接带上、与台阶扣位相对的位置均设有超声波压点，钩件沿第二连接带宽度方向间隔设置有多组，钩件通过定位环配合车缝固定在第二连接带上。
本发明的有益效果是：
1、通过在扣眼上设置向远离人体背面方向凸出的台阶扣位，使得台阶扣位与人体背面间形成了避空间隙，钩件在通过钩部扣合在台阶扣位上时，钩部前端置于避空间隙中，并不与人体背面接触，从而有效避免了钩部压迫人体背面，给人体带来不适感，相较于现有技术，整体的佩戴舒适性更好；
2、由于台阶扣位向远离扣眼的定位环底面方向凸出，在佩戴时，钩件的钩部能够更方便的扣入台阶扣位。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例一
如附图1－6所示，本发明提供的一种钩扣结构，包括：
扣眼10，其一端设有用于固定扣眼10的定位环31，另一端设有台阶扣位11，扣眼10两侧分别设有一组定位环31，扣眼10由整条金属料条一体弯折成型；
钩件20，其一端设有用于固定钩件20的定位环31，另一端设有钩部21，钩件20两侧分别设有一组定位环31，钩件20由整条金属料条一体弯折成型；
台阶扣位11向远离扣眼10的定位环31底面方向凸出，钩件20通过钩部21扣合在台阶扣位11上，从而与扣眼10扣合，在使用状态下，扣眼10的定位环31位于靠近人体一侧，即扣眼10的定位环31贴靠在人体背面上，台阶扣位11向远离人体背面的方向凸出。
具体的，通过在扣眼10上设置向远离人体背面方向凸出的台阶扣位11，使得台阶扣位11与人体背面间形成了避空间隙41，钩件20在通过钩部21扣合在台阶扣位11上时，钩部21前端置于避空间隙41中，并不与人体背面接触，从而有效避免了钩部21压迫人体背面，给人体带来不适感，相较于现有技术，整体的佩戴舒适性更好，同时，由于台阶扣位11向远离扣眼10的定位环31底面方向凸出，在佩戴时，钩件20的钩部21能够更方便的扣入 台阶扣位11。
进一步的，台阶扣位11包括U型的平扣段12和倾斜设置的斜延段13，平扣段12与扣眼10的定位环31相互平行，平扣段12通过斜延段13与扣眼10的定位环31相连，平扣段12位于扣眼10的定位环31远离底面的一侧，钩部21扣合在平扣段12上，由于平直折弯容易受力变形甚至折断，影响内衣的整体寿命，为此通过设置斜延段13，避免扣眼10形成平直折弯，同时，通过设置斜延段13，缩小平扣段12和扣眼10的定位环31与扣眼10定位环31所处平面的夹角α，从而避免平扣段12受力时，扣眼10定位环31由于受到过大的斜向牵拉，导致扣眼10定位环31的一侧压迫在人体背面上、带来不适感。
进一步的，钩件20的定位环31与钩部21间形成有扣合开口42，其中，为避免钩件20过于容易的从扣眼10中滑开，钩件20的定位环31面向钩部21一侧设有与平扣段12相配合的安全卡点22，钩部21延伸至与钩件20的定位环31相对，安全卡点22与扣合开口42相对，在钩件20与扣眼10扣合状态下，通过安全卡点22配合平扣段12对钩部21进行一定的限位，防止钩部21过于容易的从平扣段12滑出。
进一步的，安全卡点22的轴向与钩部21的轴向相同，安全卡点22的顶部形成有弧形凸起23，沿轴向，安全卡点22的两侧分别与钩件20的定位环31和钩部21形成有弧形平滑过度24，通过弧形平滑过度24和弧形凸起23。使得平扣段12能够相对平顺的扣入钩部21内，提高了扣入的平顺感，需要说明的是，虽然安全卡点22两侧设置了弧形平滑过度24，但并不影响安全卡点22配合平扣段12对钩部21形成限位作用。
进一步的，为了使钩部21能够更便捷的扣合在平扣部上，钩部21前端设有向远离扣合开口42方向翘起的翘曲部25，钩部21在扣入平扣段12时，翘曲部25能够起到导向作用。
进一步的，为了提高限位作用，钩部21前端向安全卡点22方向弯折，翘曲部25的后端与安全卡点22在扣合开口42中形成狭窄段43，翘曲部25的前端与钩件20的定位环31在扣合开口42处形成用于扣合导向的外扩导向段44。
需要说明的是，现有技术中通过平直折弯形成的平钩，在佩戴时，在受 外力压迫的情况下，平钩的一侧会整体的压迫在人体背面上，即受力点是平钩一侧的一整个平面，摩擦受力面的面积会比较大，增大了对人体背面的压迫感，通过设置翘曲部25，使得在受外力压迫时，仅在翘曲部25前端形成一个受力点，受力点会形成一个比较小面积的摩擦点，从而降低了在受外力压迫时人体背面所受到的压迫感。此外，在受外力压迫时，由于仅有翘曲部25前端的一个受力点，因为在翘曲部25前端受力时，翘曲部25后端及钩部21后端的半弧形段，能够形成一个有效的弹性缓冲，并且在外力消失后，通过弹性形变恢复推动翘曲部25前端恢复，通过弹性缓冲和弹性形变恢复，能够有效的避免钩部21由于受力发生塑性变形，提高了钩扣结构的使用寿命。
如附图7－10所示，一种内衣背扣，包括第一连接带50、第二连接带60，以及上述的钩扣结构，扣眼10设置在第一连接带50上，钩件20设置在第二连接带60上。
相同的，通过在扣眼10上设置向远离人体背面方向凸出的台阶扣位11，使得台阶扣位11与第一连接带50的带体间形成了避空间隙41，钩件20在通过钩部21扣合在台阶扣位11上时，钩部21前端置于避空间隙41中，并不会直接压迫在人体背面上，从而有效避免了钩部21压迫人体背面，给人体带来不适感，相较于现有技术，内衣背扣整体的佩戴舒适性更好，同时，由于台阶扣位11向远离扣眼10的定位环31底面方向凸出，在佩戴时，钩件20的钩部21能够更方便的扣入台阶扣位11。
进一步的，扣眼10沿第一连接带50长度方向阵列设有多排，扣眼10通过定位环31配合车缝固定在第一连接带50上，其中，第一连接带50由多层布料构成，扣眼10的定位环31包覆在布料中，台阶扣位11穿出到第一连接带50外侧，钩件20沿第二连接带60宽度方向间隔设置有多组，钩件20通过定位环31配合车缝固定在第二连接带60上，安全卡点22通过将布料顶起在第二连接带60上形成凸起卡点61，第一连接带50和第二连接带60的外边缘上通过布料的反包形成有圆角包边，并且通过圆角反包边工艺在两组的前端两侧形成柔软的圆角边位，避免外边缘形成利边、刮伤肌肤，使得内衣背扣更加亲肤，也能够防止水洗导致外边缘分层。
实施例二
本实施例与上述实施例的不同之处在于，扣眼10沿第一连接带50长度方向阵列设有多排，扣眼10通过定位环31配合车缝固定在第一连接带50上，其中，第一连接带50由多层布料构成，扣眼10的定位环31包覆在布料中，台阶扣位11穿出到第一连接带50外侧，第一连接带50上、与台阶扣位11相对的位置均通过超声波热压设有用于提高扣眼10稳固性的超声波压点51，防止扣眼10从穿出孔处滑出以及防止布层分离，钩件20沿第二连接带60宽度方向间隔设置有多组，钩件20通过定位环31配合车缝固定在第二连接带60上，安全卡点22通过将布料顶起在第二连接带60上形成凸起卡点61。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
