The invention provides a wheel device and a cart. The wheel device comprises a wheel; a pair of protective covers which are arranged on the two sides of the wheel along the axial direction of the wheel, wherein each protective cover is provided with a clamping groove; and a support which comprises a pair of connecting rods, wherein the pair of connecting rods are in one-to-one correspondence withthe pair of protective covers; and at least a part of each connecting rod is embedded into the corresponding clamping groove. According to the wheel device, the connecting rods of the support in the wheel device are at least partially embedded into the protective covers, a gap between each connecting rod and the corresponding protective cover is eliminated, and the situation that the wheel rotatesto drive foreign matter and silk threads to be wound into the protective covers and the connecting rods, and then a middle screw shaft and a wheel bearing in the wheel are damaged is avoided.
本发明提供一种车轮装置及推车,所述车轮装置包括:车轮;一对保护盖,沿着车轮的轴向装配于车轮的两侧,每一保护盖上设置卡合槽;以及支架,其包括一对连接杆,所述一对连接杆与所述一对保护盖一一对应;其中,所述连接杆至少部分嵌入所述卡合槽中。本发明中,车轮装置中支架的连接杆至少部分嵌入保护盖中,消除连接杆和保护盖之间的间隙,避免车轮转动带动异物、丝线卷入保护盖和连接杆中,进而损伤车轮中的中间螺杆轴和车轮轴承。
