一种快脱拉链的下止组件
技术领域
本发明涉及一种快脱拉链的下止组件，尤其是指一种可以有效提供拉链下端 卡定功能， 并提供拉链被快速脱开的快脱拉链的下止组件。
背景技术
拉链被用作为衣物等织物品的扣件已经是大众所公知的技术。为了将拉链应 用到织物品， 其一般都包括有下止组件。 所述下止组件， 其一般安装在拉头起点 位置的拉链端部，主要功能就是在拉头起步前将分离的左右拉链扣合在一起从而 便于拉链的拉头扣紧拉链。
现有技术中， ZL200710141666. 9所披露的 "一种带有可分离后止码的拉链" , 其能够由每个人方便地操作并且容易闭合或分开，带有可分离后止码的拉链包括: 一对左右拉链带的链牙列穿过的拉头和可分离后止码，其包括设置在拉链带之一 上的配合体和设置在另一拉链带上并且能够与配合体相接合的枢转止动体。枢转 止动体具有枢转止动部分，其能够通过将配合体从枢转止动体侧部装入枢转止动 部分中而与配合体旋转接合，并且能够通过将配合体从拉头的牙脚口通过链牙引 导通路插入枢转止动部分而与配合体旋转接合。该结构的后止码， 也即通常所说 的下止组件， 虽然其能够实现快速分离， 但是其配合体 10只有局部位置保持在 其枢转止动体 20的凹槽 26和狹缝 27中，而且其要枢转部分 12在上下方向没有 得到定位和限制，而其枢转止动部分 23呈钩状从而实际上呈悬臂状，容易断裂； 其要枢转部分 12在上下方向的力度会存在比较大的隐患， 特别是将该种拉链用 于高强度体力运动的场合， 插入凹槽 26和狹缝 27中的位于所述配合体 10上配 合板部 11由于太薄而容易破裂。 发明内容
为了解决现有技术中的问题，本发明提供一种拉链的下止组件， 包括左止件 和右止件， 所述左止件、 右止件的外侧分别连接有左拉链带、 右拉链带； 其特征 在于， 所述右止件的内侧设置有沿内侧方向延伸的右插槽和环孔， 所述环孔位于 所述右插槽的前端并与所述右插槽的槽孔前后直通，所述右插槽具有的侧边槽口 朝向所述右止件的内侧；所述左止件能够活动地插入所述右插槽的槽孔中并能够 从所述右插槽的侧边槽口中脱出； 当所述左止件插入所述右插槽的槽孔中时， 所 述左止件的顶端部能够插入到所述环孔中。
根据上述结构， 与现有技术对比可以发现其优点是：
1. 由于所述环孔位于所述右插槽的前端并与所述右插槽的槽孔前后直通， 为此实际上也相当于将所述右插槽的前端部位予以封闭，所述环孔的外侧壁大大 提高了所述右插槽的上、 下槽壁的连接结构强度， 反过来所述右插槽的上、 下槽 壁也强化了所述环孔的结构强度；
2. 由于所述左止件的顶端部能够插入到所述环孔中， 为此所述环孔能够包 容所述左止件的顶端部， 为所述左止件提供上下左右方向的定位， 甚至还可以提 供前后方向的定位；
3. 由于所述左止件能够活动地插入所述右插槽的槽孔中， 这样所述左止件 被包容收藏在所述右插槽中，所述右插槽能够为所述左止件提供上下方向的定位, 也能使所述左止件不易受到损坏， 两者结合在一起使其结构紧促；
4. 由于所述左止件能够从所述侧边槽口中脱出， 这样所述左止件从所述右 插槽和所述环孔中退出时的行程短，可以在所述左拉链带的带动下绕所述环孔的 外侧壁转动即可旋转出， 退出非常便捷。
需要说明的是， 上述方案中所定义的左、 右， 前、 后， 内、 外都是一种相对 的方位定义。
进一步的技术方案还可以是， 所述左止件的能够插入到所述环孔中的顶端部 的长度小于所述右插槽的槽孔的深度。 由于所述顶端部的长度小于所述右插槽的 深度， 为此所述左止件从所述右插槽中退出时， 完全无需原路退出任何行程而是 可以在所述左拉链带的带动下直接绕所述环孔的外侧壁转动即可立即旋转出， 退 出不仅便捷而且快速，所述顶端部在转动时不会受到所述右插槽的槽底壁的阻碍。 其中所述左止件的能够插入到所述环孔中的顶端部的长度， 或者说所述左止件插 入到所述环孔中的深度， 可以通过连接到所述左止件上的左拉链带来限制， 也可 以通过所述环孔的孔型来限制。
进一步的技术方案还可以是， 所述左止件包括能够插入所述右插槽的槽孔中 的内侧壁体部、 与拉链布带连接的外侧壁体部和位于所述内侧壁体部、 外侧壁体 部之间的中间过渡部； 在所述左止件的内侧壁体部的顶端设置有沿所述左止件的 内侧方向向上延伸的凸起从而使所述左止件的顶端呈 L形； 当所述左止件插入到 所述右插槽的槽孔中时， 所述凸起能够插入所述环孔中并且所述左止件的顶端壁 顶靠在所述环孔的外侧壁上。 这样所述左止件插入到所述环孔中的深度， 可以通 过所述凸起本身的高度来限制。
在上述方案中， 为了使所述凸起插入所述右插槽中以及以旋转方式退出所述 环孔时比较圆顺， 还可以是将所述凸起的顶端内側邯设置为弧形过渡状。
进一步的技术方案还可以是，所述凸起的高度小于所述右插槽的槽孔的深度。 这样所述凸起以旋转方式退出所述环孔时不会受到所述右插槽的槽底壁的阻碍。
进一步的技术方案还可以是， 所述右插槽的侧边槽口部的前端设置有相对延 伸的上延伸臂和下延伸臂， 所述上延伸臂和下延伸臂之间的间隙空间形成所述右 插槽的前侧边槽口， 所述左止件的内侧壁体部的厚度大于中间过渡部的厚度从而 形成所述左止件的内侧台阶； 所述右插槽的前侧边槽口的间距小于所述内侧台阶 的厚度但大于所述中间过渡部的厚度， 所述右插槽的剩余侧边槽口间距大于所述 内侧台阶的厚度。
根据本方案， 所述右插槽侧边槽口实际上呈阶梯型， 其中所述前侧边槽口的 间距小于其余侧边槽口的间距， 并且所述内侧台阶也能够被限定的所述前侧边槽 口内， 这样所述左止件插入到所述右插槽的槽孔中时， 所述左止件的内侧壁体部 被包容在所述右插槽中， 通过所述内侧台阶及所述凸起， 大大提高了所述左止件 和所述右止件之间的横向抗拉强度； 当所述左止件需要退出时， 仅仅只需在所述 左拉链带的带动下后退所述前侧边槽口的距离后就可以接着直接绕所述前侧边槽 口的台阶转动即可立即旋转出， 退出不仅便捷而且快速。 其次所述上延伸臂和下 延伸臂又能提高所述侧边槽口的结构强度，使所述右插槽不易受外力冲击而破裂。
进一步的技术方案还可以是， 所述凸起的厚度小于所述前侧边槽口的间距， 这样当所述左止件退出时， 在所述内侧台阶退出所述前侧边槽口时， 所述凸起就 可以直接从所述前侧边槽口中滑出， 而所述左止件的其余部位就可以直接从所述 其余侧边槽口中滑出。
另一种实施方案还可以是， 所述右插槽的侧边槽口部设置有相对延伸的上延 伸臂和下延伸臂， 所述上延伸臂和下延伸臂之间的间隙空间形成所述右插槽的侧 边槽口， 所述左止件的内侧壁体部的后部的厚度大于中间过渡部的厚度从而形成 所述左止件的后部内侧台阶； 所述右插槽的侧边槽口的间距小于所述后部内侧台 阶的厚度但大于位于所述中间过渡部的厚度， 也大于所述左止件的内侧壁体部的 其余部位的厚度。 根据本方案， 所述左止件插入到所述右插槽的槽孔中时， 由于 后部内侧台阶能够被限定在所述右插槽内， 这样通过所述后部内侧台阶及所述凸 起， 大大提高了所述左止件和所述右止件之间的横向抗拉强度； 当所述左止件需 要退出时， 仅仅只需在所述左拉链带的带动下后退所述后部内侧台阶的距离后就 可以接着直接从所述右插槽中拔出， 退出不仅便捷而且快速。
进一步的技术方案还可以是， 所述左止件、 右止件的尾端内侧设置有相互扣 合的扣合装置。 这样可以借助于所述扣合装置， 将所述左止件、 右止件的尾端相 互扣紧定位。
与现有技术对比，本发明的下止组件中的所述左止件与所述右止件在拉链锁 合时在上下内外方向上不仅相互定位可靠， 而且连接的结构强度高， 并且也非常 容易实现相互快速分离。 由于本发明具有上述特点和优点， 为此可以应用到拉链 的下止组件中。 附图说明

下面结合附图对本发明的具体实施方式作进一步说明。
如图 1、 图 2所示， 一种拉链的下止组件， 包括左止件 2和右止件 1 , 所述 左止件 2、 右止件 1的外侧分别连接有左拉链带 21、 右拉链带 13 , 它们之间通 过注塑方式连接成型。 在所述左拉链带 21、 右拉链带 13的内侧还分别注塑连接 有能够相互扣接的左链牙 11和右链牙 12。锁合拉链时，先将拉头（图中未画出） 放置在所述右止件 1的尾端，并将所述左止件 1穿过拉头后再插入到所述右止件 1中，再拉动拉头就可以将所述左链牙 11和右链牙 12锁合起来。需要说明的是， 本方案中所定义的左、 右， 前、 后， 内、 外等都是一种相对的方位定义。
如图 1和图 2所示， 所述右止件 1的内侧设置有沿内侧方向延伸的右插槽 11和环孔 10 , 所述环孔 10位于所述右插槽 11的前端， 所述环孔 10与所述槽孔 3所组成的通道前后直通， 并直通到所述右止件 1尾端和前端。 所述右插槽 11 具有的侧边槽口 18朝向所述右止件 1的内侧，在该结构中， 所述右插槽 11的槽 孔 3 包括有内侧壁 31、 上壁体 32和下壁体 33 , 所述右插槽 11的侧边槽口 18 部位设置有相对延伸的上延伸臂 17和下延伸臂 16 , 所述上延伸臂 17和下延伸 臂 16之间的间隙空间形成所述右插槽 11的侧边槽口 18。 所述环孔 10与所述右插槽 11的不同点在于所述环孔 10具有外侧壁 15 , 并 用所述外侧壁 15将所述上壁体 32和下壁体 33连接起来，这样所述环孔 10不仅 能够用于收容保持所述左止件 1的顶端部 23 , 为所述左止件 1的顶端部 23提供 上下左右前后方向的定位，而且所述环孔 10的外侧壁 15大大提高了所述右插槽 11 的槽孔 3的上、 下槽壁 （32、 33 ) 的连接结构强度； 反过来， 所述上延伸臂 17和下延伸臂 16及上、 下槽壁 （32、 33 ) 又能增强所述环孔 10的结构强度。
如图 1和图 1所述，所述左止件 1能够沿方向 a从所述右止件 1的尾端或从 所述右止件 1的内侧活动地插入所述右插槽 11的槽孔 3中， 所述左止件 1的顶 端部 23也能够延伸插入到所述环孔 10中，所述左止件 1的被包容在所述右插槽 11的槽孔 3中， 所述槽孔 3的上、 下槽壁 （32、 33 ) 能够可靠地限制所述左止 件 1在上下方向上的移动；所述左止件 1的顶端部 23插入到所述环孔 10中的深 度，可以通过所述左拉链带 21顶抵在所述环壁 15上的方式予以定位，还可以是 通过适当改变所述环孔 10与所述顶端部 23之间的配合形状予以定位，即通过所 述环孔 10限制所述顶端部 23的插入深度。
所述左止件 1的高度小于所述侧边槽口 18的高度 dl ,从而在所述左链牙 11 与右链牙 12相对分开时（拉头打开或人为地撕开）， 所述左止件 1能够在所述左 拉链带 21的带动下绕所述环孔 10的外侧壁 15转动即可从所述侧边槽口 18中旋 转滑出， 退出非常便捷
为了防止所述左止件 1退出时其顶端部 23与所述右插槽 11的内侧壁 31发 生憋死问题，其中一种方案是将所述顶端部 23的顶端内侧部 24设置为弧形过渡 状，其二是将所述顶端部 23相对于所述左拉链带 21的凸出高度设置为小于所述 右插槽 11的槽孔 3的槽深度， 该槽深度是所述内侧壁 31到槽口 18的距离。 这 样所述左止件 1从所述右插槽 11中退出时， 完全无需原路退出任何行程而是可 以在所述左拉链带 21的带动下直接绕所述环孔 10的外侧壁 15转动即可立即从 所述侧边槽口 18中旋转出， 退出不仅便捷而且快速， 所述顶端部 23在转动时不 会受到所述右插槽 11的槽底壁 31的阻碍。
第二种实施结构是如图 3和图 4所示，所述左止件 1包括能够插入所述右插 槽 11的槽孔 3中的内侧壁体部 25、 与拉链布带连接的外侧壁体部 27和位于所 述内侧壁体部 25、外侧壁体部 27之间的中间过渡部 26 ; 在所述左止件 1的内侧 壁体部 25的顶端设置有沿所述左止件 1的内侧方向向上延伸的凸起 231从而使 所述左止件 3的顶端呈 L形； 当所述左止件 1插入到所述右插槽 11的槽孔 3中 时， 所述左止件 1的内侧壁体部 25被包容在所述右插槽 11的槽孔 3中， 所述凸 起 231能够插入所述环孔 10中并且所述左止件 1的顶端壁 28顶靠在所述环孔 10的外侧壁 15上。 所述左止件 2插入到所述环孔 10中的深度， 可以通过所述 凸起 231本身的高度或者说所述顶端壁 28来限制。 所述凸起 231相对于所述顶 端壁 28的凸起高度小于所述右插槽 11的深度，这样所述凸起 231以旋转方式退 出所述环孔 10时不会受到所述右插槽 11的内侧壁 31 (也称槽底壁） 的阻碍。 在上述方案中， 为了使所述凸起 231插入所述右插槽 11中以及以旋转方式退出 所述环孔 10时比较圆顺， 还可以是将所述凸起 231的顶端内侧部 241设置为弧 形过渡状。
本方案还可以是， 如图 3、 图 4、 图 5、 图 6所示， 在所述右插槽 11的侧边 槽口部 18的前端部位设置相对延伸的上延伸臂 17和下延伸臂 16 , 所述上延伸臂 17和下延伸臂 16之间的间隙空间形成所述右插槽 11的前侧边槽口 181 , 所述左 止件 1的内侧壁体部 25的厚度大于中间过渡部 26的厚度从而形成所述左止件 2 的内侧台阶；所述右插槽 11的前侧边槽口 181的间距小于所述内侧台阶的厚度但 大于所述中间过渡部 26的厚度， 所述右插槽 11的剩余侧边槽口 182的间距大于 所述内侧台阶的厚度。 根据本方案， 所述右插槽 11侧边槽口 18实际上呈阶梯型 包括所述前侧边槽口 181和其余侧边槽口 182 , 其中所述前侧边槽口 181的间距 小于其余侧边槽口 182的间距， 所述内侧台阶所在的位置也就是所述内侧壁体部 25所在的位置。 这样， 当所述左止件 1插入到所述右插槽 11的槽孔 3中时， 所 述上延伸臂 17和下延伸臂 16能够伸入到所述中间过渡部 26 , 而所述内侧台阶能 够被限定的所述前侧边槽口 181 内但其能够从所述其余侧边槽口 182中脱出。 通 过所述内侧台阶与所述前侧边槽口 181的配合， 补强所述凸起 231承受横向拉力 的强度， 大大提高了所述左止件 2和所述右止件 1之间的横向 （图 5中所示的方 向 D )抗拉强度； 当所述左止件 1需要退出时， 如图 7所示， 仅仅只需在所述左 拉链带 21的带动下后退所述前侧边槽口 181的距离后，所述凸起 231就可以接着 直接绕所述前侧边槽口 181的台阶转动 （图 7所示 b方向） 即可立即从所述其余 侧边槽口 182中旋转出， 退出不仅便捷而且快速。 其次所述上延伸臂 17和下延伸 臂 16又能提高所述侧边槽口 18的结构强度，使所述右插槽 11不易受外力冲击而 破裂。
为了进一步减少所述凸起 231退出的障碍， 还可以是， 将所述凸起 231的厚 度设置为小于所述前侧边槽口 181的间距， 这样当所述左止件 2退出时， 在所述 内侧台阶退出所述前侧边槽口 181时， 所述凸起 231就可以直接从所述前侧边槽 口 181 中滑出， 而所述左止件 1的其余部位就可以直接从所述其余侧边槽口 182 中滑出。
为了帮助所述左止件 1和所述右止件 1之间的尾端在前后和左右方向的定位， 在所述左止件 1的尾端内侧设置有稍微倾斜的倒钩槽 29 , 在所述右止件 1的尾端 内侧设置有与所述倒钩槽 29适配的尾部凸起 19。 当所述左止件 1插入到所述右 止件 1中时， 所述倒钩槽 29与所述尾部凸起 19相互扣合， 从而所述倒钩槽 29与 所述尾部凸起 19共同形成相互扣合的扣合装置。所述相互扣合的扣合装置能够增 强所述左止件 1和所述右止件 1之间的定位强度和稳定性。
第三种方案还可以是如图 8所示， 与上述图 3、 图 4、 图 5、 图 6所示方案不 同的是，所述右插槽 11的侧边槽口 18位置设置相对延伸的上延伸臂 17和下延伸 臂 16 , 所述上延伸臂 17和下延伸臂 16之间的间距也大致相同， 所述左止件 1的 内侧壁体部 25的后部的厚度大于中间过渡部 26的厚度从而形成所述左止件 1的 后部内侧台阶 251 ; 所述右插槽 11的侧边槽口 18的间距小于所述后部内侧台阶 251的厚度但大于位于所述中间过渡部 26的厚度， 也大于所述左止件 1的内侧壁 体部 25的其余部位 252的厚度。根据本方案， 所述右插槽 11侧边槽口 18间距虽 然大致相同， 但所述左止件 1插入到所述右插槽 11的槽孔 3中时， 由于后部内侧 台阶 251 能够被限定在所述右插槽 11 的槽孔 3 内， 这样通过所述后部内侧台阶 251及所述凸起 231 ,大大提高了所述左止件 1和所述右止件 1之间的横向抗拉强 度； 当所述左止件 1需要退出时， 仅仅只需在所述左拉链带 21的带动下后退所述 后部内侧台阶 251的距离后， 就可以接着直接从所述右插槽 11的侧边槽口 18中 拔出， 退出不仅便捷而且快速。
