                                    背景技术
现有技术中，三轮供儿童乘坐的手推车由前腿、前腿上的前轮、后腿、后腿上的后轮、前后端分别铰接在前腿和后腿上的篮框杆、与前腿相铰接的推手杆所组成，后腿的上端部铰接在推手杆上。这种供儿童乘坐的手推车的折叠后的体积大，不便于收藏及携带。
                                    发明内容
本发明的目的在于提供一种折叠后体积小的供儿童乘坐的手推车。
本发明的技术方案是：一种供儿童乘坐的手推车，前轮支架上设有前轮，后轮支架上设有后轮，后轮支架的上端部分别与前轮支架的后端部及前推杆的前端部相铰接，推手杆与前推杆的后端部相铰接，上支撑杆的上端部与推手杆相铰接，上支撑杆与后轮支架相铰接，上支撑杆的下端部与下支撑杆相铰接，下支撑杆的下端部与后篮框杆相铰接，后篮框杆的后端部与后轮支架相铰接，后篮框杆的前端部与前篮框杆的后端部相铰接，前篮框杆的前端部与前轮支架相铰接。
本发明与现有技术相比具有下列优点：
打开后整车的刚性好，在整车折叠后，推手杆的推把朝上，便于操作。整车折叠或打开的操作仅操作推把即可完成。整车的折叠后体积小。
                                    附图说明
下面结合附图及实施例对本发明作进一步的描述：
附图1为本发明实施例一的打开时的原理示意图；
附图2为本发明实施例一的半折叠时的原理示意图；
附图3为本发明实施例一的全折叠时的原理示意图；
附图4为本发明实施例二的打开时的结构主视图；
附图5为本发明实施例二的半折叠时的结构主视图；
附图6为本发明实施例二的全折叠时的结构主视图；  其中：
1、前轮；2、下支撑杆；3、后轮支架上连接块；4、前推杆；5、推手杆；6、上支撑杆；7、后轮支架；8、后轮；9、后篮框杆；10、前篮框杆；11、前轮支架；12、前座垫杆；13、靠背杆；14、后座垫杆；15、后支撑杆；16、后踏脚板；17、前踏脚板；
                            具体实施方式
参见附图1至3，一种供儿童乘坐的手推车，前轮支架11上设有前轮1，后轮支架7上设有后轮8，后轮支架7的上端部分别与前轮支架11的后端部及前推杆4的前端部相铰接，推手杆5与前推杆4的后端部相铰接，上支撑杆6的上端部与推手杆5相铰接，上支撑杆6与后轮支架7相铰接，上支撑杆6的下端部与下支撑杆2相铰接，下支撑杆2的下端部与后篮框杆9相铰接，后篮框杆9的后端部与后轮支架7相铰接，后篮框杆9的前端部与前篮框杆10的后端部相铰接，前篮框杆10的前端部与前轮支架11相铰接。
参见附图4至附图6，前轮支架11的上部或后轮支架7的上部铰接有前座垫杆12的前部，所述的前座垫杆12的后端部与后座垫杆14的前端部相铰接，所述的下支撑杆2的上端部与所述的后座垫杆14相铰接。所述的后座垫杆14的后部还铰接有后支撑杆15的上端部，后支撑杆15的下端部与后篮框杆9或后轮支架7相铰接。所述的后座垫杆14或前座垫杆12上铰接有靠背杆13的下端部，靠背杆13与后座垫杆14或前座垫杆12之间设有靠背杆角度锁定机构，该角度锁定机构用于调节靠背杆13向前倾斜或向后倾斜。所述的后座垫杆14的后部设有后踏脚板16。所述的前轮支架11的下部设有前踏脚板17。所述的靠背杆13的前方的前座垫杆12上设有前座垫，所述的靠背杆13的后方的后座垫杆14上设有后座垫。前座垫是在婴儿朝前坐时使用，它与前踏脚板17相配合使用，此时靠背杆13向后倾斜；后座垫是在婴儿朝后坐时使用，它与后踏脚板16相配合使用，而此时靠背杆13向前倾斜。
参见附图，所述的上支撑杆6与推手杆5的铰接处位于前推杆4与推手杆5的铰接处的前部。所述的后轮支架7的上端部的后侧与前推杆4的前端部相铰接，所述的后轮支架7的上端部前侧与前轮支架11的后端部相铰接。
所述的推手杆5与前推杆4之间设有锁定机构。在该锁定机构解锁时，可以把本发明折叠。该锁定机构锁定时，本发明可处于稳定的打开状态。
