Description

手摇轮椅转向机构
本实用新型涉及手摇轮椅转向机构技术领域。
现有的手摇轮椅转向机构其转向角度很小,给使用者带来很大不便,当在有限空间转向时,由于其转弯半径太大,要反复操作多次才能实现转弯目的。
本实用新型的目的是设计一种手摇轮椅转向机构,在车架前端固定连接着前叉转向支撑,使其转向角度增大,可使操作者非常方便的完成转弯目的。
本实用新型是这样实现的:前叉1上有前轮20,前轮20轴上固定有被动链轮9和大飞轮倒闸2,转动手柄8的轴上固定有驱动链轮7,驱动链轮7与传动介轮6之间连接着驱动刹车链条I 3,传动介轮6与被动链轮9之间连接者驱动刹车链条II 4,横传动支架10上有介轮轴12支撑者传动介轮6,其特征是:车架13固定连接着前叉转向支撑5,前叉转向支撑5固定连接轴套19,前叉轴16通过轴套19在紧固螺栓I 17作用下与竖传动支架22连接,转动手柄8与前后调节中轴架18连接,前后调节中轴架18插入横传动支架10内,横传动支架10上有紧固螺栓II 21,横传动支架10与竖传动支架22固定连接在一起。
本实用新型的优点是:构思新颖,设计巧妙,转向角度增大可使操作者非常方便的转弯,由于竖传动支架和横传动支架可调节使不同身高的使用者都可舒适的操作该轮椅。
下面结合附图,用实施例对本实用新型做进一步说明:
图1主视图,图2为在图1A向的视图,图3横传动支架局部视图,图4竖传动支架局部视图。
由于车架13前端固定连接着前叉转向支撑5,前叉转向支撑5固定连接轴套19,前叉轴16通过轴套19在紧固螺钉17作用下与竖传动支架22连接使前轮20的转向角度增大;前后调节中轴架18插入横传动支架10内,通过紧固螺栓II 21可移动前后调节中轴架18;通过紧固螺栓I 17可移动竖传动支架22。
