Description

Technical Field

[0001] The utility model mainly relates to the technical field of household appliance bases, and in particular to a plastic mobile chassis for small household appliances. Background Art

[0002] Among small household heaters, baseboard heaters are used frequently in winter. Due to their limited heating range, users need to move the heater according to their location. In the current iteration of heater product design, the shapes of the heater's legs are varied and mostly fixed. If self-locking universal wheels are directly installed on the heater's legs, it will damage the integrity of the product's appearance design. Therefore, a mobile chassis is usually provided to users as an option.

[0003] Currently, most mobile chassis are made of an injection-molded one-piece plastic chassis plus self-locking universal wheels to adapt to the legs of different heaters, which results in insufficient product compatibility design.

[0004] The inventor proposed a plastic mobile chassis for small household appliances, which can adapt to the feet of different heater products. At the same time, self-locking universal wheels are installed under the support plate to facilitate users to move the placement of the heater according to their own needs. Utility Model Content
