As we all know, household appliances such as washing machines need to be transported to all parts of the country for sale after they are produced and assembled in factories. It is inevitable that the washing machine will be bumped during loading, unloading and transportation. In order to reduce the damage of the washing machine during handling and transportation, it is often necessary to pack the washing machine, and a buffer is added in the packing, which is generally made of a foam material.

However, the buffers added in the packaging of existing washing machines have not been adaptively designed according to the casing structure of the washing machine, such as the buffer support at the bottom of the washing machine. Reinforcement. The problem with this buffer support method is that the support part of the buffer support at the bottom is not the strongest part of the washing machine cabinet. In the actual loading and unloading or transportation process, the washing machine cabinet is deformed due to insufficient support strength, causing losses to the enterprise.
