Abstract

本发明公开了一种拉链链牙，包括齿顶、齿根，齿顶与齿根之间由齿肩过渡形成整体，齿顶上开设有凹槽，齿肩靠近齿根的一端设置有与齿顶的凹槽相对应的齿肩护台；齿根的两侧根壁呈向内凹陷的弧形，且齿顶呈球形曲面状，且齿肩护台与齿顶的凹槽相对应的前端为半圆弧形。用本发明的链牙制成的拉链，柔软而易弯曲且闭合较顺滑。

Description

一种拉链链牙
技术领域
本发明涉及一种拉链链牙。
背景技术
现有的拉链链牙，其结构一般包括齿顶、齿根，齿顶与齿根之间由齿肩过渡形成整体，齿顶上开设有凹槽，齿肩靠近齿根的一端设置有与齿顶的凹槽相对应的齿肩护台，齿根中部设有接纳链带的带筋槽、链带槽，链带槽向着齿根根壁开口，在齿根根壁链带槽口缘的两侧，链带槽的槽壁向开口方向延伸后在此形成了两个链带护台。这种拉链链牙，由于其齿根的两侧根壁为平板状，用这样的链牙制成拉链后，链牙自身占用拉链的空间较大(即，齿与齿之间的空间较小)，制成的拉链较硬不易弯曲。
发明内容
本发明的目的是提供一种可节省链牙自身所占用拉链的空间、制成的拉链较柔软而易弯曲的拉链链牙。
本发明的技术方案是这样的：一种拉链链牙，包括齿顶、齿根，齿顶与齿根之间由齿肩过渡形成整体，齿顶上开设有凹槽，齿肩靠近齿根的一端设置有与齿顶的凹槽相对应的齿肩护台；上述齿根的两侧根壁呈向内凹陷的弧形。
上述齿顶呈球形曲面状。
上述齿肩护台与上述齿顶的凹槽相对应的前端为半圆弧形。
采用上述方案后，本发明的一种拉链链牙，齿根的两侧根壁呈向内凹陷的弧形，制成拉链后，节省了链牙自身所占用拉链的空间，即加大了齿与齿之间的空间，从而使制成的拉链柔软而易弯曲，而且，两侧根壁呈向内凹陷的弧形，使制成的拉链更加美观。且本发明中，齿顶设计为球形曲面状，加大了拉链两侧链牙的齿顶在闭合过程中相互之间的滑度，减小了闭合过程中两侧齿顶之间的相互摩擦，使整个闭合过程较顺滑。且本发明中，齿肩护台与齿顶的凹槽相对应的前端为半圆弧形，使拉链在闭合过程中，任意一侧的齿肩护台在嵌入另一侧齿顶的凹槽时变得更加顺滑。
附图说明
图1为本发明的结构示意图。
图2为本发明的使用状态示意图。
具体实施方式
本发明的一种拉链链牙，如图1、图2所示，包括齿顶1、齿根2，齿顶1与齿根2之间由齿肩3过渡形成整体。起啮合作用的齿顶1呈球形曲面状，且齿顶1上开设有凹槽11；齿肩3靠近齿根2的一端设置有与齿顶的凹槽11相对应的齿肩护台31，齿肩护台31与齿顶的凹槽11相对应的前端为半圆弧形；齿根2的两侧根壁21呈向内凹陷的弧形，且齿根2中部设有接纳链带的带筋槽4、链带槽5，链带槽5向着齿根2根壁开口，在齿根2根壁链带槽口缘的两侧，链带槽的槽壁向开口方向延伸后在此形成了两个链带护台6。
