The universal wheel comprises a connecting main body, a connecting column is arranged on the connecting main body, a first groove is formed in the upper surface of the connecting column, a first connecting rod is connected to the interior of the first groove through a bearing, a third groove and a fourth groove are formed in the two sides of the connecting main body, a bearing is arranged in the third groove, and a second connecting rod is connected to the interior of the fourth groove through a bearing. A connecting shaft is arranged in the bearing, a rolling wheel is arranged on the side, away from the third groove, of the connecting shaft, and a clamping spring is installed on the inner side wall of the clamping groove. The device has the beneficial effects that the bearing of the first connecting rod is connected into the connecting column, meanwhile, the rolling wheels are connected to the two sides of the connecting body through the connecting shaft and the bearing, friction of the two rolling wheels is reduced, and the device can rotate by 360 degrees and is simple in structure, few in part and convenient to maintain and install. External tables and chairs can be connected together through the clamping springs on the outer sides of the first connecting rods, the structure is simple, and installation is convenient.
一种万向轮,包括连接主体,所述的连接主体上设有连接柱,所述的连接柱的上表面开设有第一凹槽,所述第一凹槽的内部通过轴承连接有第一连接杆,所述的连接主体的两侧内部设有第三凹槽和第四凹槽,所述的第三凹槽内设有轴承,所述的轴承内设有连接轴,所述的连接轴远离第三凹槽的一侧设有滚动轮,所述的卡槽内侧壁安装有卡簧。本发明的有益效果为:本发明的第一连接杆轴承连接在连接柱内,同时滚动轮通过连接轴和轴承连接在连接主体的两侧,两个滚动轮减少摩擦,使得本装置可360度旋转,结构简单,零件少,方便维修和安装。本发明通过第一连接杆外侧的卡簧可外部的桌椅连接在一起,结构简单,方便安装。
