The invention relates to the technical field of universal wheels, and discloses a universal wheel device capable of preventing chippings from being wrapped into a wheel to make the wheel difficult to rotate, the universal wheel device comprises a connecting rod, a connecting shaft penetrates through the top side wall of the connecting rod, a supporting rod penetrates through the side wall of the connecting rod, and the bottom end of the supporting rod is fixedly connected with an arc-shaped cover; a roller penetrates through the inner side wall of the arc-shaped cover, a center column is rotationally connected to the axis of the side wall of the roller, and a movable ring penetrates through the outer side wall of the roller. When the movable ring projects out of a part outwards, the inner side wall of the movable ring pulls out a section of the pull rod outwards and drives the movable rod to move towards the outer ring, the movable rod drives the push rod to extend towards the outer ring, and the side wall of the push rod drives the supporting frame to pop up the movable frame to the side wall of the movable column and support the movable frame towards the outer ring. Due to the fact that the outer side wall of the movable frame is bulged towards the outer ring, the arc-shaped frame is bulged outwards at the moment, scraps can be pushed outwards from the side wall of the rolling wheel, and the situation that the rolling wheel is clamped by the scraps and cannot move is avoided.

    本发明涉及万向轮技术领域,且公开了一种避免碎屑裹进车轮而使车轮难以转动的万向轮装置,包括连接杆,所述连接杆的顶侧壁处贯穿有连接轴,连接杆的侧壁中贯穿有支撑杆,支撑杆的底端固定连接弧形罩,弧形罩的内侧壁中贯穿有滚轮,滚轮的侧壁处轴心处转动连接有中心柱,滚轮的外侧壁处贯穿有活动环。由于活动环向外弹出一部位时,活动环的内侧壁处将拉杆向外拉出一节,同时带动移动杆向外圈移动,移动杆带动推杆向外圈扩伸,推杆的侧壁带动支撑架将活动架冲活动柱的侧壁处弹起并向外圈撑起,由于活动架的外侧壁是向外圈鼓起的,此时就会将弧形架向外鼓起,可将碎屑从滚轮侧壁处向外推动,避免滚轮被碎屑卡住无法移动。
