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卷单层防插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，提供一种双卷单层防插拉链，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：双卷单层防插拉链包括有链座、链条以及钢卷尺，钢卷尺包括有上钢卷尺以及下钢卷尺，链座与链条以及钢卷尺的外壳连接；链座设有左链槽以及右链槽，链条包括有左链条、右链条、链头封口件以及链尾封口件，左链条以及右链条与链头封口件以及链尾封口件连接；左链条与左链槽连接，右链条与右链槽连接；左链条设有左链扣以及左链布，左链扣与左链布连接，左链扣设有左防插片、左上链钩以及左下链钩，左链扣、左防插片、左上链钩以及左下链钩由一体的材料构成；右链条设有右链扣以及右链布，右链扣与右链布连接，右链扣设有右防插片、右上链钩以及右下链钩，右链扣、右防插片、右上链钩以及右下链钩由一体的材料构成；上钢卷尺设有上钢卷带，上钢卷带的上头端与链条的链头封口件连接，上钢卷带与左上链钩以及与右上链钩动配合连接，上钢卷带位于链座的上方；下钢卷尺设有下钢卷带，下钢卷带的下头端与链条的链头封口件连接，下钢卷带与左下链钩以及右下链钩动配合连接，下钢卷带位于链座的下方；左防插片位于每个左链扣之间的位置，右防插片位于每个右链扣之间的位置，利用左防插片以及右防插片封住左链扣以及右链扣之间的间隙，增加不法分子插开上链条的难度；当不法分子用利器插入链条时，利器被上钢卷带以及下钢卷带挡住，使不法分子难以插开链条。
双卷单层防插拉链的使用方法是：使用时，将左链布、右链布与行 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，使左链条与右链条咬合扣接在一起，将行李箱的箱口封闭；上钢卷尺跟随链座移动，上钢卷带随着钢卷尺移动被拉出，拉出的上钢卷带被左上链钩以及右上链钩扣在链座的上面，将左链条与右链条的闭合口上方封住；同时，下钢卷尺跟随链座移动，下钢卷带随着下钢卷尺移动被拉出，拉出的下钢卷带被左下链钩以及右下链钩扣在链座的下面，将左链条与右链条的闭合口下方封住；左链条与右链条闭合时，左防插片移动到位于一个左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链扣与另一个右链扣之间位置，利用左防插片挡住一个左链扣与另一个左链扣之间的间隙，利用右防插片挡住一个右链扣与另一个右链扣之间的间隙，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，使闭合的左链条与右链条分开；同时，上钢卷带跟随链座反方向移动，上钢卷带在上钢卷尺扭簧的弹力作用下收回上钢卷尺内；以及下钢卷带跟随链座反方向移动，下钢卷带在下钢卷尺扭簧的弹力作用下收回下钢卷尺内。
本发明的有益效果是：使用时，将双卷单层防插拉链设置于行李箱上，双卷单层防插拉链设有上钢卷尺以及下钢卷尺，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链扣以及右链扣之间的间隙，利用上钢卷带以及下钢卷带封住链条，当不法分子利用利器插入链条时，增加不法分子用利器插开拉链的难度。
