Description

一种拉链 技术领域
本发明涉及一种拉链。
背景技术
现有的拉链，通常包括链牙、拉头、两链带，两片链带的相对侧边分别嵌有一列链牙，两列链牙相互错位啮合，拉头卡在链带相对侧板的链牙上。拉链通常应用于衣服、手袋等，如果利用尖锐的物品就会很容易地将拉链的链牙从咬合部位分离开来。这样的状况在应用于手袋时，往往会较容易被偷窃。
发明内容
本发明要解决的技术问题是提供一种结构简单、可以防止咬合的链牙被分离的拉链。
为达到上述目的，本发明的技术方案是：一种拉链，包括链牙、拉头、两链带，两片链带的相对侧边分别嵌有一列链牙，两列链牙相互错位啮合，拉头卡在链带相对侧板的链牙上，所述链牙包括头部、设于头部上位于头部与链带之间的卡接杆，所述头部靠近另一链带的侧面上设有卡接部，当两排链牙啮合时卡接部卡接于卡接杆上。
优选的，所述卡接杆有两个，分别设于链牙的左右侧面。
优选的，所述卡接杆为椭圆杆。
优选的，所述头部靠近卡接杆的一侧的左右两端分别设有圆弧倒角。
上述技术方案具有如下有益效果：通过在链牙的头部上设有卡接部，在头部与链带之间设有卡接杆，通过卡接部与卡接杆的配合从而可以防止拉链的链牙被分离，从而使得拉链的保护性更强，更具有实用性；进一步的，卡接杆设置的数量为两个，分别位于链牙的左右侧面，从而使每个链牙都可以跟相对一侧的两个链牙的卡接杆相卡接，从而使得整个拉链的连续性、卡接性更强、更紧密。
附图说明
图1是本发明结构示意图；
图2是图1中A-A处的剖视图。
具体实施方式
下面结合附图和具体的实施方式对本发明作进一步详细说明。
图1、图2所示，本实施例提供一种拉链，包括链牙1、拉头、两链带2，两片链带2 的相对侧边分别嵌有一列链牙1，两列链牙1相互错位啮合，拉头卡在链带2相对侧板的链牙1上，所述链牙1包括头部11、设于头部11上位于头部11与链带2之间的卡接杆12，所述头部11靠近另一链带2的侧面上设有卡接部111，当两排链牙1啮合时卡接部111卡接于卡接杆12上。所述卡接杆12有两个，分别设于链牙1的左右侧面。所述卡接杆12为椭圆杆。所述头部11靠近卡接杆12的一侧的左右两端分别设有圆弧倒角112。
上述的链牙，通过头部上卡接部设置为圆弧形，该圆弧的弧长小于圆周的一半，该圆弧的半径略大于卡接杆的短半径，从而能够更好地配合；上述链牙的头部通过设置圆弧倒角，可以更好地实现左右两排链牙的卡接配合。
通过在链牙的头部上设有卡接部，在头部与链带之间设有卡接杆，通过卡接部与卡接杆的配合从而可以防止拉链的链牙被分离，从而使得拉链的保护性更强，更具有实用性；进一步的，卡接杆设置的数量为两个，分别位于链牙的左右侧面，从而使每个链牙都可以跟相对一侧的两个链牙的卡接杆相卡接，从而使得整个拉链的连续性、卡接性更强、更紧密。
以上仅是本发明一个较佳的实施例，本领域的技术人员按权利要求作等同的改变都落入本案的保护范围。
