Description

一种儿童安全座椅可拆装式跨带 技术领域
本实用新型涉及一种可拆装式跨带，尤其涉及一种儿童安全座椅可拆装式跨带。
背景技术
现有的儿童安全座椅中的跨带，跨带与儿童安全座椅都是整体式，在使用的过程中导致一定的不便，遇到特殊的情况，使安全系数降低。
中国专利201420474392.0，公开一种儿童汽车座上跨带调节结构，所述儿童汽车座包括供儿童乘坐的座椅本体、设于所述座椅本体上的跨带、与所述跨带的上部可打开或扣合的安全带，其特征在于：所述跨带通过所述跨带调节结构在所述座椅本体上前后位置可调地设置，所述跨带调节结构包括可沿前后方向滑动地设于所述座椅本体上的滑动件，所述跨带的底部固定地连接在所述滑动件上，当所述安全带与所述跨带相连接时，所述安全带拉动所述跨带与所述滑动件前后运动而使得所述跨带贴紧在儿童的裆部。此结构是跨带的调节机构，只能调节跨带的松紧，无法拆卸跨带，在操作方面存在一定的不便，无法提升使用安全性能。
实用新型内容
本实用新型主要是解决现有技术中存在的不足，提供一种结构紧凑度高，拆装方便，同时进一步使用安全性和操作便利性的一种儿童安全座椅可拆装式跨带。
本实用新型的上述技术问题主要是通过下述技术方案得以解决的：
一种儿童安全座椅可拆装式跨带，包括椅座和可拆卸跨带，所述的可拆卸跨带通过锁止组件与椅座呈活动式启闭，所述椅座中设有跨带插入孔；
所述的锁止组件包括锁壳、止转舌和解锁按钮铁片，所述的锁壳中设有与跨带插入孔相连通的跨带插入槽，所述的锁壳中设有沿锁壳进行弹性转动的锁舌，所述的锁舌与跨带插入槽呈配接式分布，所述的可拆卸跨带与锁舌呈活动式配接；
所述的止转舌沿锁壳进行限位滑动，所述的止转舌与锁舌呈活动式配接，所述的止转舌与锁壳呈弹性连接，所述的解锁按钮铁片的一端通过解锁按钮进行位移，所述的解锁按钮与解锁按钮铁片呈弹性连接，所述的解锁按钮铁片的另一端通过解锁按钮拨杆驱动止转舌进行位移。
作为优选，所述的可拆卸跨带的底部设有与锁舌呈活动锁止的跨带锁定环，所述的锁舌与锁壳通过锁舌扭簧进行弹性回位，所述的止转舌外套有与锁壳呈弹性连接的止转舌弹簧，所述的解锁按钮外套有按钮复位弹簧。
作为优选，所述的解锁按钮设在椅座的外壁，所述的解锁按钮拨杆呈“Z”状。
机构部件说明：
1.解锁按钮：按一下按钮，在机构的作用下锁舌转动解锁，跨带可以拆卸。
2.按钮复位弹簧：失去外力，按钮在弹簧作用下回去原始位置。
3.解锁按钮铁片：用螺丝和按钮固定成一体，把按钮前推的动作传递给解锁拨杆。
4.解锁按钮拨杆：把按钮动作传递给止转舌，拨动止转舌前后滑动。
5.止转舌：沿着锁壳上的长槽前后滑动，用来锁住锁舌。
6.止转舌弹簧：始终给止转舌一个往前点的推力。
7.锁壳：固定在安全座椅上，其上有止转舌的滑动轨道，和固定锁舌转动销的孔。
8.锁舌：通过旋转来锁定跨带锁定环，锁住跨带。
9.锁舌转动销：锁舌可以绕着销轴转动，同时用来固定左右锁壳。
10.锁舌扭簧：提供锁舌一个解锁的旋转力。
11.跨带锁环：跨带的一部分，锁住环就是锁住了整个跨带。
工作原理：
止转舌锁住锁舌，锁舌锁住跨带锁定环，跨带被牢牢固定住不能拆卸。
用手指往左推动解锁按钮，在按钮推动下解锁按钮铁片也往左滑动，在铁片的推动下，解锁按钮拨杆做一定角度的转动，拨杆上端拨动止转舌沿着锁壳上的滑槽往右运动，止转舌脱开锁舌的锁定面。
止转舌脱开锁舌的锁定面，机构解锁，在锁舌扭簧的作用下，锁舌绕着锁壳上的销轴做逆时针转动一定角度，转到最大角度使，这时跨带锁定环脱钩失去了锁舌的限制，整个跨带可以拆卸下来。
如果跨带需要重新安装的话，只要下压跨带，在跨带锁环的下压作用力下，锁舌做顺时针旋转，转到一定角度，止转舌在止转舌弹簧的作用下往左滑动深入锁舌锁定面，不让其逆时针旋转，锁住锁舌，锁舌同时锁住跨带锁定环，跨带被牢牢固定住不能拆卸
因此，本实用新型的一种儿童安全座椅可拆装式跨带，结构紧凑，拆卸方便，进一步提升使用安全性能。
