Description

双层封闭拉链的使用方法 技术领域
本发明涉及一种安全拉链的使用方法，特别是一种双层封闭拉链的使用方法。
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封闭拉链的使用方法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，提供一种双层封闭拉链的使用方法，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：双层封闭拉链包括有链座、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6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，钢卷带与左上链条以及右上链条动配合连接，钢卷带位于链座的上方；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。
双层封闭拉链的使用方法是：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，拉出的钢卷带被左上链条的左上链扣以及右上链条的右上链扣扣在链座的上面，将左上链条与右上链条的闭合口上方封住；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，将双层封闭拉链设置于行李箱上，双层封闭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。

为了实施利用钢卷尺4的钢卷带16封住上链条2以及下链条3的闭合口，以及保持链条2以及链条3的闭合以及分开功能，左上链扣18设有左弯钩26，右上链扣21设有右弯钩29；左下链条13设有左下链扣24以及左下链布25，左下链扣24与左下链布25连接；右下链条14设有右下链扣27与右下链布28，右下链扣27与右下链布28连接；左下链布25以及右下链布28与左上链布20以及右上链布23连接，左下链布25、右下链布28、左上链布20以及右上链布23与链头封口件11以及链尾封口件12连接；钢卷带16与左上链扣18以及右上链扣21动配合连接，钢卷带16位于左弯钩26与右弯钩29之间，左弯钩26以及右弯钩29位于左上链槽5以及右上链槽6的上方，利用左弯钩26以及右弯钩29钩住钢卷带16；链座1包括有上链板30、上合链柱31、中链板32、下合链柱33以及下链板34，上链板30与上合链柱31连接，上合链柱31与中链板32连接，中链板32与下合链柱33连接，下合链柱33与下链板34连接；或者，上链板30、上合链柱31、中链板32、下合链柱33以及下链板34由一体的材料构成；上链板30设有导轮43，钢卷带16经过导轮43与链头封口件11连接；钢卷尺4的外壳15与上链板30连接；左上链槽5由上链 板30以及中链板32与上合链柱31的左边构成，左上链槽5位于上合链柱31的左边；右上链槽6由上链板30以及中链板32与上合链柱31的右边构成，右链槽6位于上合链柱31的右边；左下链槽7由中链板32以及下链板34与下合链柱33的左边构成，左下链槽7位于下合链柱33的左边；右下链槽8由中链板32以及下链板34与下合链柱33的右左边构成，右下链槽8位于下合链柱33的右边。
为了使钢卷带16以及上链板30能于左弯钩26与右弯钩29之间移动，左弯钩26与右弯钩29之间的距离大于钢卷带16的宽度，使钢卷带16能于左弯钩26与右弯钩29之间移动；左弯钩26与右弯钩29之间的距离大于上链板30的宽度，使上链板30能于左弯钩26与右弯钩29之间移动；左弯钩26的左钩尾35到右弯钩29的右钩尾36的距离小于钢卷带16的宽度；钢卷带16位于上链板30与左钩尾35以及右钩尾36之间；使钢卷带16不能脱离左弯钩26以及右弯钩29。
为了实施左上链扣18与右上链扣21的动配合连接，一个左上链扣18与另一个左上链扣18之间的左间隙37比左防插片19的宽度大0.2毫米至0.5毫米；一个右上链扣21与另一个右上链扣21之间的右间隙38比右防插片22的宽度大0.2毫米至0.5毫米；左上链扣18的宽度与右上链扣21的宽度相等；左防插片19的宽度与右防插片22的宽度相等；左上链扣18的宽度与左防插片19的宽度相等，右上链扣21的宽度与右防插片22的宽度相等。
为了利用锁具锁住链座1，其特征在于：所述的钢卷尺4设有动锁孔39，链尾封口件12设有定锁孔41，以方便利用锁具将链座1与链尾封口件12锁在一起。
双层封闭拉链的使用方法是：使用时，将左上链布20、右上链布23、右下链布28以及左下链布25与行李箱的箱口连接，并使钢卷尺4上的拉手40位于行李箱外；封闭行李箱时，手抓拉手40牵引钢卷尺4以及链座1移动，链座1跟随拉手40移动，使左上链条9与右上链条10咬合扣接在一起，以及使左下链条13与右下链条14咬合扣接在一起，将行李箱的箱口封闭；同时，钢卷尺4跟随链座1移动，钢卷带16随着钢卷尺4移动被拉出，拉出的钢卷带16被左上链条9的左上链扣18以及右上链条10的右上链扣21扣在链座1的上面，将左上链条9与右上链条10的闭合口 上方封住；左上链条9与右上链条10闭合时，左防插片19移动到位于一个左上链扣18与另一个左上链扣18之间的位置，以及右防插片22移动到位于一个右上链扣21与另一个右上链扣21之间位置，利用左防插片19挡住一个左上链扣18与另一个左上链扣18之间的间隙，利用右防插片22挡住一个右上链扣21与另一个右上链扣21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40牵引链座1反方向移动，链座1跟随拉手40移动，使闭合的左上链条9与右上链条10分开，以及使左下链条13与右下链条14分开；同时，钢卷带16跟随链座1反方向移动，钢卷带16在钢卷尺4扭簧的弹力作用下收回钢卷尺4内。
所述的防插拉链封闭行李箱时，手抓拉手40牵引外壳15以及链座1移动，左上链扣18以及左防插片19由左上链槽5导入，右上链扣21以及右防插片22由右上链槽6导入，左下链扣24由左下链槽7导入，右下链扣27由右下链槽8导入，利用链座1的左上链槽5、右上链槽6使左上链扣18与右上链扣21咬合连接，利用左下链槽7以及右下链槽8使左下链扣24与右下链扣27咬合连接；同时，左防插片19跟随左上链扣18移动到一个左上链扣18与另一个左上链扣18之间的左间隙37的位置；右防插片22跟随右上链扣21移动到一个右上链扣21与另一个右上链扣21之间的右间隙38的位置；同时，钢卷尺4跟随链座1移动，钢卷带16随着钢卷尺4移动被拉出，拉出的钢卷带16被左弯钩26的左钩尾35以及右弯钩29的右钩尾36扣在左弯钩26以及右弯钩29内，被拉出钢卷带16位于上链板30与左钩尾35以及右钩尾36之间。
所述的左上链扣18与右上链扣21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。
所述的左上链条9与右上链条10咬合扣接在一起时，钢卷尺4跟随链座1移动，上链板30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上链条9与右上链条10闭合的长度成正比或者相等；左上链条9与右上链条10分开时，钢卷尺4跟随链座1反方向移动，上链板30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内的长度与左上链条9与右上链条10分开的长度成正比或者相等。
所述的左上链条9与右上链条10闭合时钢卷尺4被拉出的钢卷带16长度大于左上链条9与右上链条10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；所述的每个左防插片19与相邻的左上链扣18动配合连接，每个右防插片22与相邻的右上链扣21动配合连接。
为了减少钢卷带16移动的摩擦力，所述的导轮43设有铰轴42，上链板30设有铰孔44，导轮43的铰轴42与上链板30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。
