Description

双层保护拉链 技术领域
本发明涉及一种安全拉链，特别是一种双层保护拉链。
背景技术
目前，行李箱或者行李袋使用的拉链，由于拉链的强度不够，在使用的过程中，不法分子用利器插入拉链，就可以将拉链划开，一种防止拉链被划开的双层保护拉链已成为提高拉链强度以及防盗的需要。
发明内容
本发明的目的是克服现有技术的不足，提供一种双层保护拉链，用于提高拉链强度以及提高拉链的防盗性能。
本发明所采用的技术方案是：双层保护拉链包括有链座、上链条、下链条以及钢卷尺，链座与上链条、下链条以及钢卷尺连接；链座设有左上链槽、右上链槽、左下链槽以及右下链槽，上链条包括有左上链条、右上链条、链头封口件以及链尾封口件，下链条包括有左下链条以及右下链条；左上链条、右上链条、左下链条以及右下链条与链头封口件以及链尾封口件连接；左上链条与左上链槽连接，右上链条与右上链槽连接，左下链条与左下链槽连接，右下链条与右下链槽连接；钢卷尺包括有外壳以及钢卷带，钢卷带的头端与上链条的链头封口件连接，钢卷带与左下链条以及与右下链条动配合连接，钢卷带位于链座的下方；左上链条设有左上链扣、左防插片以及左上链布，左上链扣与左防插片由一体的材料构成，左上链扣与左上链布连接；右上链条设有右上链扣、右防插片以及右上链布，右上链扣与右防插片由一体的材料构成，右上链扣与右上链布连接；左防插片位于每个左上链扣之间的位置，右防插片位于每个右上链扣之间的位置，利用左防插片以及右防插片封住左上链扣以及右上链扣之间的间隙，增加不法分子插开上链条的难度；当不法分子用利器插入上链条以及下链条时，利器被钢卷带挡住，使不法分子难以插开上链条以及下链条。
双层保护拉链的使用方法是：使用时，将左上链布、右上链布、右下链布以及左下链布与行李箱的箱口连接，并使钢卷尺上的拉手位于行李箱外；封闭行李箱时，手抓拉手牵引钢卷尺以及链座移动，链座跟随拉手 移动，使左上链条与右上链条咬合扣接在一起，以及使左下链条与右下链条咬合扣接在一起，将行李箱的箱口封闭；同时，钢卷尺跟随链座移动，钢卷带随着钢卷尺移动被拉出，拉出的钢卷带被左下链条的左下链扣以及右下链条的右下链扣扣在链座的下面，将右下链条与右下链扣的闭合口下方封住；左上链条与右上链条闭合时，左防插片移动到位于一个左上链扣与另一个左上链扣之间的位置，以及右防插片移动到位于一个右上链扣与另一个右上链扣之间位置，利用左防插片挡住一个左上链扣与另一个左上链扣之间的间隙，利用右防插片挡住一个右上链扣与另一个右上链扣之间的间隙，增加不法分子利用利器插开拉链的难度；打开行李箱的箱口时，用手通过拉手牵引链座反方向移动，链座跟随拉手移动，使闭合的左上链条与右上链条分开，以及使左下链条与右下链条分开；同时，钢卷带跟随链座反方向移动，钢卷带在钢卷尺扭簧的弹力作用下收回钢卷尺内。
本发明的有益效果是：使用时，将双层保护拉链设置于行李箱上，双层保护拉链设有两层链条以及钢卷尺，上链条设有左防插片以及右防插片，利用左防插片以及右防插片封住左上链扣以及右上链扣之间的间隙，利用钢卷尺的钢卷带封住两层链条，当不法分子利用利器插入链条时，利器被钢卷带挡住，增加不法分子用利器插开拉链的难度。

所述的左下链扣24与右下链扣27咬合扣接在一起时，左弯钩26的左钩尾35与右弯钩29的右钩尾36距离小于钢卷带16的宽度，使钢卷带16被扣在左弯钩26与右弯钩29内，以避免钢卷带16脱离左弯钩26以及右弯钩29。
所述的左下链条13与右下链条14咬合扣接在一起时，钢卷尺4跟随链座1移动，下链板34跟随拉手40于左弯钩26与右弯钩29之间移动，钢卷带16被牵引出的长度与左下链条13与右下链条14闭合的长度成正比或者相等；左下链条13与右下链条14分开时，钢卷尺4跟随链座1反方向移动，下链板34跟随拉手40于左弯钩26与右弯钩29之间移动，钢卷带16回收到钢卷尺4内的长度与左下链条13与右下链条14分开的长度成正比或者相等；所述的左下链条13与右下链条14闭合时钢卷尺4被拉出的钢卷带16长度大于左下链条13与右下链条14分开时钢卷尺4被 拉出的钢卷带16长度。
所述的上链条2以及下链条3闭合时，链座1向链尾封口件12方向移动移动，上链条2以及下链条3随着链座1的移动而不断闭合；上链条2以及下链条3分开时，链座1向链头封口件11方向移动移动，上链条2以及下链条3随着链座1的移动而不断分开。
为了减少钢卷带16移动的摩擦力，导轮43设有铰轴42，下链板34设有铰孔44，导轮43的铰轴42与下链板34的铰孔44铰接；钢卷带16由钢卷尺4被牵引出来时，钢卷带16压住导轮43，钢卷带16驱动导轮43转动，减少钢卷带16与导轮43的摩擦力；钢卷带16被钢卷尺4收回时，钢卷带16压住导轮43，钢卷带16驱动导轮43转动，减少钢卷带16与导轮43的摩擦力。
