一种便携式儿童滑车，如图1-6所示，包括滑车本体1、座垫2、折叠轮架3、前轮4、后轮5和把手6，座垫2设置在滑车本体1上，座垫2上可以设置海绵等，使得孩子能够舒适的玩耍。滑车本体1底部凹设第一安装槽11，折叠轮架3安装在第一安装槽11内。其中，折叠轮架3包括折叠底座31、折叠臂32和快装机构33，折叠底座31的下表面凹设第二安装槽34，折叠臂32设置两个，分别通过转轴转动设置在第二安装槽34的两端，快装机构33设置在折叠臂32的端部；展开时，折叠臂32突出于折叠底座的两端；当折叠时，折叠臂32隐藏于第二安装槽34内；前轮4设置在快装机构33上，后轮5分设在滑车本体1的尾部的两侧；滑车本体1的前部凸出设置安装块12，安装块12的竖直方向(滑车本体1的高度方向)设置第一插孔13，安装块12的左右方向(滑车本体1的长度方向)设置第二插孔14，并且延伸至滑车本体1内；安装块12的前后方向(滑车本体1的宽度方向)设置插销孔15，并且穿过第一插孔13和第二插孔14具有重叠部分，把手6上设置锁孔61，把手6可切换的设置在第一插孔13和第二插孔14内，并且通过插销7连接插销孔15和锁孔61。当折叠轮架3展开时，把手6插入第一插孔13内，并且通过插销7将把手6固定，此时为一辆儿 童滑车。而当折叠轮架3折叠后，同时将把手6插入第二插孔14内，此时相当于一个能够拖行的旅行箱，家长只需要单手即可将其拖行。
在一实施例中，如图1-3所示，滑车本体1内设置储物腔16，座垫2与滑车本体1的前部铰接，其尾部通过锁扣固定。实现座垫2的打开和锁定。其中，锁扣结构具有较多结构，且为现有技术，在此不在过多赘述。该储物箱16能够将取下的前轮4进行收纳，同时也能够放置一些随行物品。
在一实施例中，如图1-9所示，快装机构33包括连接轴331、插拔块332、隔离套333和锁块334，连接轴331固定设置在折叠臂32上，其可以通过焊接的方式连接，也可以为一体结构。连接轴331的一端凹设安装孔，安装孔为长方体结构，并且在其两端设置贯穿的引导孔，锁块334滑动设置在两端的引导孔内，隔离套333设置在安装孔内，并且与安装孔固定连接，插拔块332包括与隔离套内孔配合的块本体335和设置在块本体端部的磁铁336，插拔块332插入隔离套333内，锁块334为磁铁，当磁铁336与锁块334磁极相同时，锁块334突出于引导孔；当磁极相反时，锁块334隐没于引导孔内。其中，前轮4包括连接部41和滚动部42，滚动部42通过轴承滚动连接在连接部41上，连接部41与快装机构33连接。连接部41轴向设置贯穿的通孔，在通孔内设置连接孔43，当前轮4与快装机构33连接时，锁块334插入连接孔43内。当安装前轮4时，插入插拔块332，使得插拔块332与两侧锁块334的磁极相反，锁块334隐没于引导孔内，而后将前轮套在连接轴331上，并且使得锁块334与前轮4内的连接孔43对应，拔除插拔块332，转动180°后插入，使得插拔块332与两侧锁块334的磁极相同，锁块334被推出引导孔插入前轮4的连接孔43内，完成前轮4的快速安装；当拆卸时，只需要改变插拔块332的磁极以吸引锁块334，使得锁块334隐没于引导孔内，即可将前轮4拆除。另外，由于前轮4套入连接轴331后无法观察到连接孔43，使得安装不便，但对于利用磁铁同极相斥的原理，只需要将前轮4套入后就改变插拔块332的磁极，使得锁块334向外顶出，此时，锁块334定在前轮4的通孔的内壁上，只需要调节前轮4的位置，直至听到“啪嗒”的声音，即说明锁块334插入前轮4 的连接孔43内。
在上述实施例中，如图1-9所示，磁铁336与隔离套333间隙配合，块本体335与隔离套333紧配合。优选的，块本体335采用塑料制成，因塑料相比于金属易被压缩，因此，插拔块332在插入时更加方便。
在一实施例中，如图1-9所示，锁块334包括锁块本体337和锁定部338，锁定部338设置在锁块本体337上，并且呈阶梯结构，引导孔为与锁块配合的阶梯孔，锁块本体337为磁铁。利用阶梯结构的引导孔与隔离套333配合，保证锁块334处于引导孔内，并且不会与连接轴331分离。优选的，引导孔为长方体孔状结构。
在一实施例中，如图1-9所示，连接轴331侧壁对称设置定位平面339，前轮4的通孔与连接轴331配合。即通孔内设置有与定位平面339配合的平面，当两平面贴合时，保证锁块334与连接孔43对应。
在一优选实施例中，如图1-9所示，连接轴331由塑料制成。隔离套33也可为塑料制成，这样能够减少对磁铁的影响；当然，也可以采用其他不被磁铁吸引的材料。
在一实施例中，如图1-9所示，第二安装槽34的内壁上设置固定孔37，固定孔37与折叠臂32折叠处于位置时的锁块334位置相对应。因此，当折叠臂32处于折叠位置时，将锁块334推出插入固定孔37内，即可完成折叠臂32与折叠底座31的锁定。
在一实施例中，如图1-9所示，折叠轮架3还包括C形卡箍36，C形卡箍36设置四个，分别设置在折叠臂32的旋转中心的两侧，用于固定折叠臂32，防止其转动。
在一实施例中，如图1-11所示，插销孔15的端部设置沉孔17，沉孔17内设置磁环，插销7的端部设置铁块71，利用磁环吸附铁块71。使得插销7隐没于沉孔17内。为了方便插销7取出，在铁块71上设置手握槽，提供家长取出时的施力点。
在一实施例中，如图1-11所示，把手6呈T字形，并且在其侧壁上对 称设置轴向的导槽62，并且在第一插孔13和第二插孔14内对应位置设置导条18。首先，导条18与导槽61配合，能够防止把手6转动；另外，能够快速调节至插销孔15与锁孔61对齐。
本发明在使用时，如图1-11所示，将折叠臂32展开，并且将前轮4安装，将把手6插入第一插孔13内，通过插销7锁定，此时为一辆滑车；同时，折叠臂32突出部分与前轮4之间能够作为孩子脚踏板，家长手拉把手6，能够拖动孩子前行。当把前轮4拆下，能够将前轮4放入储物腔16内，将把手6插入第二插孔14内，并且将折叠臂32旋转入第二安装槽34内，卡入C形卡箍36，同时更换插拔块332使得锁块334插入固定孔37，实现折叠臂32的收纳。此时，家长只需要单手拉动手把6，即可实现拖行，方便滑车的搬运。
以上仅为本发明的较佳实施例，并非用来限定本发明的实施范围；如果不脱离本发明的精神和范围，对本发明进行修改或者等同替换，均应涵盖在本发明权利要求的保护范围当中。
