Description

手推车
技术领域
本发明涉及一种手推车，尤其是一种可做二轮手推车或四轮平台式手推车变换的手推车。
背景技术
目前常见的手推车有二轮与四轮两种，分别提供两种不同的使用方式，可由使用者视其实际需要选用，换言之，既有的手推车只能在单一形式下工作，然而搬运工作进行时，因货物的性质不同，有时使用立式推车较为简单便捷，有时使用平台式推车则将较为平稳且易于操作。但由上述可知，不论是立式或平台式推车，均只能以其中一种形式使用，对于必须交替使用两种推车的使用者而言，即必须分别购置前述两种不同形式的推车，此不仅将增加花费，闲置时亦有占用空间的问题。本发明的发明人人便开发出了申请号为US6,938,905、US7,600,765的技术方案来解决上述问题，但上述专利仍存在一定的缺陷，如US7,600,765专利中的关节结构不易定位且结构复杂。
发明内容
为解决关节结构容易发生晃动的问题，本发明提供一种简便易行且更为稳固可靠、可依使用者需要实现两轮车推车或四轮平台板车变换的手推车。
本发明的技术方案如下：
一种手推车，包括车架、轮组、手把以及连接车架和手把的关节结构，所述车架包括承载板和框杆，所述轮组设于框杆上，框杆与关节结构相连接的端部设有定位部和套合部，其特征在于：所述关节结构包括枢接块和分别枢设于枢接块两端的圆柱形的枢接座。
所述枢接块的两端凸设有圆弧状的枢接体,枢接体上分别设有枢接孔,中央设有定位凸体。
所述枢接座的一端为套合体，套合体与所述框杆的套合部匹配相接，枢接座的另一端的端面上设有挡持面，并沿轴向开设有枢接槽，于枢接槽的两侧边设置枢接孔。
所述手把的两端设有套合部，并与所述枢接座的套合体匹配相连接。
所述手把上设有可滑动的定位滑套，定位滑套的下部设有U形定位凹面，当手把与车架的框杆呈90度角或者称直线状时，定位滑套向下滑动使枢接座以及枢接块的定位凸体套合于U形定位凹面中。
所述两个定位滑套的中间设有连接两个定位滑套的防止定位滑套转动的滑套连杆。
手把上定位滑套的上方还设有定位杆。
本发明的手推车可依使用者需要做简单的折收组合变化，占用空间小，可完成两轮车推车或四轮平台板车的变换。本发明的关节结构与定位滑套配合定位，当手把与车架的框杆呈90度角或者称直线状时，定位滑套向下滑动使枢接座以及枢接块的定位凸体套合于U形定位凹面中，故不易发生晃动，更为牢固可靠。

具体实施方式
如图1-6所示的手推车，包括车架1、轮组2、手把3以及连接车架1和手把3的关节结构，车架1包括承载板13和框杆10，轮组2设于框杆10上，框杆10与关节结构相连接的端部设有定位部11和套合部12，关节结构包括枢接块40和分别枢设于枢接块40两端的圆柱形的枢接座41、42，枢接块40的两端凸设有圆弧状的枢接体400，枢接体400上分别设有枢接孔4000，中央设有定位凸体401，枢接座41、42的一端为套合体411，套合体411与框杆的套合部12匹配相接，枢接座41、42的另一端的端面上设有挡持面4100、4200，并沿轴向开设有枢接槽410和枢接槽420，于枢接槽410和枢接槽420的两侧边设置枢接孔4101和枢接孔4201，枢接孔4101、4201与直立壁面4102、4202约呈90°角。
手把3的两端设有套合部31，并与枢接座的套合体421匹配相连接，手把3上设有可滑动的定位滑套30，定位滑套30的穿孔300套在手把3上，定位滑套30的下部设有U形定位凹面301，当手把3与车架1的框杆10呈90度角或者称直线状时，定位滑套30向下滑动使枢接座41以及枢接块40的定位凸体401套合于U形定位凹面301中。
为防止定位滑套30转动以便更方便的套接关节结构，两个定位滑套30的中间设有连接两个定位滑套的滑套连杆。
为了使手把3更好的定型，手把3上定位滑套30的上方还设有定位杆32。
组合时，将关节结构的枢接座41、42与枢接块40用枢接组件N由枢接孔4101、4201穿入定位组成关节结构，再将关节结构的套合体411、421分别套合定位于车架1的套合部12与手把3的套合部31内，这样即可组合出一可收合的手推车结构。
当需要使用两轮推车时，将手把3与车架1展开成一直线，此时关节结构上的枢接座41、42则被展开，枢接块40两端的枢接体400可在枢接座41、42的枢接槽410、420中转动，当枢接块40之定位凸体401端面抵持于枢接槽410、420之挡持面4100、4200上时，即手把3与车架1已成一直线了，再将定位滑套30下推，使关节结构完全被定位滑套30包覆定位，如此，即可完成实用且方便的两轮手推车。
当使用四轮平台式板车时，将框杆10上的轮组2的轮子调整到定位后，将手把3上的定位滑套30上拉，再将手把3上折至与车架1约呈90°，此时将定位滑套30下压使枢接座41完全被包裹，并使枢接座42被套合于定位滑套30的U形定位凹面301上，此时关节结构即完全被定位滑套30套合定位，这样，即可完成一四轮平台式手推车。
