其中，解锁开关能控制固定销从档位槽11中脱离，解锁开关与导轨硬连接，轨道4的长度方向与导轨的长度方向一致，使得解锁开关在轨道4内移动时能带动导轨在套管的通道3内移动；这种利用第一拆分件1和第二拆分件2组装后就能形成轨道4的设计，减少轨道4加工工序，提高生产效率。
可选地，结合图1、图2、图3、图4所示，所述顶板12的后侧边间隔设有多个凹槽121，所述第一后侧板23的顶边对应设有与所述凹槽121配合的凸块231。
其中，凹槽121的深度方向位于前后方向上，凸块231的高度方向位于上下方向上，当凹槽121与凸块231组装后，顶部与第一后侧板23能实现相互垂直连接；本实施例中设置相互配合的凹槽121和凸块231，既方便第一拆分件1和第二拆分件2实现快速高效的相互组装，又能增强第一拆分件1与第二拆分件2相互连接的强度。
可选地，结合图1、图2、图3、图4所示，所述第一拆分件1的一端设有第一连接部14，所述第二拆分件2设有与所述第一连接部14配合的第二连 接部24。
其中，通过第一连接部14和第二连接部24相互配合连接，以确保第一拆分件1和第二拆分件2能相互牢固连接；第一连接部14与第一拆分件1相互一体成型设置，第二连接部24与第二拆分件2相互一体成型设置。
可选地，结合图1、图2、图3、图4所示，所述第一连接部14包括与所述第一底板21抵接的第二底板141和从所述第二底板141的前后两侧边分别向上延伸出的第三前侧板142和第二后侧板143，所述第三前侧板142与所述第二前侧板22抵接，所述顶板12的后侧边向下延伸形成第三后侧板144；所述第二连接部24包括从所述第一后侧板23延伸形成的第四后侧板241，所述第二后侧板143和所述第三后侧板144均与所述第四后侧板241的后表面抵接。
其中，第一底板21和第二底板141位于同一平面，以便导轨能顺利在通道3内移动，且第一底板21和第二底板141相互抵接连接，能增强整体的结构强度；第二底板141的强度要求较低，其上设有镂空结构，以减轻整体结构的重量；第三前侧板142与第二前侧板22位于同一平面，且第三前侧板142的上端面与第二前侧板22的上端面齐平，以便解锁开关内顺利在轨道4内移动，且第二前侧板22和第三前侧板142相互抵接，能增强整体结构的强度；第三前侧板142上远离第二前侧板22的一端向上继续延伸并与第一前侧板13连接，使得轨道4的一端被封闭设计，以防止解锁开关从轨道4内脱离；第四后侧板241与第一后侧板23位于同一平面，第二后侧板143的前表面和第三后侧板144的前表面均与第四后侧板241的后表面抵接，实现双层叠加，这种双层叠加的设计能大大提升套管后侧面的受力强度，从而提升第一连接部14和第二连接部24相互连接的强度；第一连接部14和第二连接部24各自本身的结构都是一体成型的部件，整体结构的抗变形强度大。
可选地，结合图1、图2、图3、图4所示，所述第一连接部14还包括从所述顶板12的后侧边向上延伸出的第一竖向固定耳145和从所述第二底板141的后侧边向后延伸出的第一横向固定耳146，所述第二连接部24还包括从所述第四后侧板241的上侧边向上延伸出的第二竖向固定耳242和从所述第四后侧板241的下侧边向后延伸出的第二横向固定耳243；所述第一竖向固 定耳145设有多个第一安装孔1451，所述第二竖向固定耳242对应设有与所述第一安装孔1451重叠的第二安装孔2421，所述第一横向固定耳146设有多个第三安装孔1461，所述第二横向固定耳243对应设有多个第四安装孔2431。
其中，第一安装孔1451、第二安装孔2421、第三安装孔1461和第四安装孔2431的数量均优选为两个，各个安装孔内可安装螺钉等连接件，以便将套管与儿童安全座椅进行固定连接，将数量设计为两个，既能确保套管与儿童安全座椅相互连接的稳固性，又能尽量不影响各个固定耳的抗变形强度；将第一连接部14的第一竖向固定耳145与第二连接部24的第二竖向固定耳242进行叠加设置，以及将第一连接部14的第一横向固定耳146与第二连接部24的第二横向固定耳243进行叠加设置，不仅组装方便，而且叠加形成的固定耳的抗变形强度更大，使得套管能与儿童安全座椅牢固连接，提升安全性。
可选地，结合图1、图2、图3、图4所示，所述第一竖向固定耳145的形状大小与所述第二竖向固定耳242的形状大小一致，和/或，所述第一横向固定耳146的形状大小与所述第二横向固定耳243的形状大小一致。
其中，将第一竖向固定耳145的形状大小设计的与第二竖向固定耳242的形状大小一致，使得第一拆分件1和第二拆分件2相互组装后，第一竖向固定耳145与第二竖向固定耳242能完全重叠，使得竖向固定耳整体的结构强度更大；同理，将第一横向固定耳146的形状大小设计的与第二横向固定耳243的形状大小一致，使得横向固定耳整体的结构强度更大。
可选地，结合图1、图2、图3、图4所示，所述第二横向固定耳243延伸出有三角加强板244，所述三角加强板244与所述第四后侧板241之间形成有与所述第二后侧板143配合的插槽245。
其中，三角加强板244与第二横向固定耳243位于同一平面，三角加强板244与第四后侧板241相互垂直设置，三角加强板244与第四后侧板241之间形成的插槽245的宽度与第二后侧板143的厚度尺寸相近，第一拆分件1和第二拆分件2相互组装后，第二后侧板143能与插槽245相互紧配，插槽245具有一定的长度，通过第二后侧板143与插槽245的相互配合，起到第一拆分件1和第二拆分件2相互组装时预定位的作用。
可选地，结合图1、图2、图3、图4所示，所述第二拆分件2设有镂空部25。
其中，第二拆分件2的抗变形强度要求较低，因此在第二拆分件2的第一后侧板23和第一底板21分别设置镂空部25，以降低套管整体结构的重量。
可选地，结合图1、图2所示，所述第一拆分件1和所述第二拆分件2通过全焊接连接的方式相互固定连接。
其中，全焊接连接是指将第一拆分件1与第二拆分件2的相互连接处全部进行焊接操作，使得由第一拆分件1和第二拆分件2相互组装成的套管具有更高的结构强度；具体为，第一后侧板23的顶边与顶边的后侧边相互焊接连接，第一底板21与第二底板141相互焊接连接，第三前侧板142与第二前侧板22相互焊接连接，第二后侧板143和第三后侧板144与第四后侧板241的后表面焊接连接，第一竖向固定耳145与第二竖向固定耳242相互焊接连接，第一横向固定耳146与第二横向固定耳243相互焊接连接。
本发明另一实施例提供了一种儿童安全座椅，包括如上所述的ISOFIX套管。
本发明中的儿童安全座椅，第一拆分件1采用厚度更厚的材料制作而成，使得第一拆分件1的抗变形强度增大，从而使得设置在第一拆分件1上的档位槽11在受固定销作用力时不会发生变形，且ISOFIX套管由第一拆分件1和第二拆分件2这两个部件组装而成，零件少，产品功能稳定性高，还可节省设备、人工等方面的成本，另外只需加厚第一拆分件1的厚度，而不会受固定销作用力的第二拆分件2的厚度减薄或保持原有厚度，能降轻整体结构的重量和尽量节省材料成本。
虽然本公开披露如上，但本公开的保护范围并非仅限于此。本领域技术人员在不脱离本公开的精神和范围的前提下，可进行各种变更与修改，这些变更与修改均将落入本发明的保护范围。
