The invention relates to the technical field of universal wheels, and discloses a universal wheel device capable of keeping standing according to the advancing direction of a wheel, which comprises asupport plate, a movable hole is formed in the side wall of the support plate, a fitting plate is movably connected to the bottom side of the support plate, a connecting plate is fixedly connected tothe bottom of the fitting plate, and a movable column penetrates through the interior of the connecting plate; and a connecting shaft penetrates through the bottom end of the side wall of the movablecolumn. In the rotating process of the movable ring, the movable ball is scraped, so that the movable ball tilts in an arc shape, the movable ball hooks the arc block upwards, the bottom of the arc block gets close to the center of the connecting plate, the side wall of the upper end of the elastic column at the bottom and the side wall of the movable ring are extruded, and the supporting rod penetrating through the interior of the elastic column is pulled at the moment; the side wall of the supporting rod is limited by the cross plate and becomes straight, and lines in the bottom of the supporting frame are straightened, so that the supporting frame is opened, the box can stand on the ground at the moment when the box stops, and the box is prevented from rolling at will.

    本发明涉及万向轮技术领域,且公开了一种可根据轮子前进方向来保持站立的万向轮装置,包括支撑板,支撑板的侧壁处开设有活动孔,支撑板的底侧活动连接有贴合板,贴合板的底部固定连接有连接板,连接板的内部贯穿有活动柱,活动柱的侧壁底端贯穿有连接轴。活动圈旋转的过程中会刮动到活动球,使得活动球弧形翘起,活动球将弧块向上勾起,弧块的底部向连接板的中心部位靠拢,使得底部的弹力柱上端的侧壁处和活动圈的侧壁处进行挤压,此时将弹力柱内部贯穿的支撑杆进行拉动,支撑杆的侧壁受到交叉板的限制,可变得笔直,并将支撑架的底部内部的线条给拉直,使得支撑架张开,可在箱子停下的瞬间站立在地面上,避免箱子随意滚动。
