The invention provides a trundle assembly structure, a trundle and a household appliance, relates to the technical field of trundle, and solves the technical problems of low efficiency and high production rejection rate during trundle assembly. The trundle assembling structure comprises a mounting support, an axial limiting assembly and a radial limiting assembly, and one end of the mounting support is in rotatable clearance fit with a trundle; the other end of the mounting bracket is in clearance fit with a mounting hole in a to-be-mounted position; the axial limiting assembly is arranged between the trundle and a to-be-mounted position so as to axially limit the trundle; the radial limiting assembly is arranged between the mounting support and the to-be-mounted position so as to limit the trundle in the radial direction. The mounting bracket is in clearance fit with the trundles and the base, so that the problems of low mounting efficiency, poor assembly consistency and high part rejection rate during interference fit connection of the trundles are solved; and through the axial limiting assembly and the radial limiting assembly, it is guaranteed that the installation position is fixed after clearance fit is adopted.

    本发明提供了一种脚轮装配结构、脚轮及家用电器,涉及脚轮技术领域,解决了脚轮装配时低效、生产报废率高的技术问题。该脚轮装配结构,包括安装支架、轴向限位组件、径向限位组件,安装支架一端与脚轮可转动间隙配合;安装支架另一端与待安装位置的安装孔间隙配合;轴向限位组件设置在脚轮和待安装位置之间,以对脚轮轴向进行限位;径向限位组件设置在安装支架和待安装位置之间,以对脚轮径向进行限位。本发明通过将安装支架与脚轮和底座之间均设置成间隙配合结构,解决脚轮过盈配合连接时存在的安装效率低、装配一致性差以及零件报废率高的问题;通过轴向限位组件和径向限位组件,保证采用间隙配合后的安装位置固定。
