The utility model relates to a switch zipper, which relates to the technical field of suitcase clothing accessories and security theft prevention. Inspection line of zipper state is arranged on zipper, which is distributed across zipper at intervals of several segments; each section of the detection line of zipper is composed of a middle chain teeth switch connected in series with a flexible conductor segment on both sides of the chain; the chain teeth switch is composed of one or more pairs of conductive chain teeth which engage and lead through material selection, surface treatment and compact meshing structure. Flexible conductor segment can be made by coating conductive film, coating conductive solution or even implanting conductive material into the chain, benign contact with the conductive chain teeth and extend to the outside of the chain, and arrange external contact points on the chain to lead to the detection circuit. The invention has the characteristics of distributed circuit switch and preset sensitivity index, which can effectively prevent the zipper from being opened and destroyed maliciously or accidentally, and generate real-time and measurable state signals, thus providing a technical basis for security theft prevention of bags, clothing, tents, etc. and their covering property.

开关拉链
本专利技术涉及箱包服装配件和安全防盗
技术介绍
拉链,是一种实用便捷的连接配件,广泛流行应用于各种箱包、服装、帐篷等各种包容物上。拉链的材质和结构特点,又决定了它比较脆弱,所以在安全防盗方面贵在预防及时发现与报警,而基础要求则是拉链必须是状态可检测的。“一种可发光或发声的拉链头结构”(专利技术专利申请号CN201610746575.7),通过改变拉链头结构设计产生拉动时的声光警示;“拉链带及拉链组件”(技术专利申请号CN201620215837.2),沿链带设置导电条以便随处可取电;“一种智能指纹拉链”(技术专利申请号CN201520430069.8),在拉链两头设四块带头电池,链牙内置导线与拉链头拉柄上指纹识别连通;“拉链链齿可导电的指纹识别防盗包具”(专利技术专利申请号CN201510806112.0),利用拉链拉动链齿啮合导电连接拉链头上指纹识别;“报警拉链”(技术专利申请号CN201320174185.9),在拉链两侧纵向布设两条耐洗导线,与铁质拉链头连通报警回路;“防盗拉链”(技术专利申请号CN201220106296.1),拉齿分导电与绝缘两部分,拉座设两导电柱接触拉齿拉手报警。诸如上述方案的现有技术,至少不能圆满防范两种拉链异常情况:其一,拉链被尖物(如圆珠笔)从中间捅开;其二,链布被利刃(如刀片)割裂。
技术实现思路
普通拉链的基本构成包括,两条链带,每条链带的一边固定一排链牙序列,通过拉动拉链头,拉合两排链牙相啮合而使两条链带接合,拉开两排链牙脱离啮合而使两条链带分开。拉链类型按链牙的材质分,有金属拉链、注塑拉链、尼龙拉链 ...
