[0002] Modern people's pursuit of quality in life naturally requires daily household appliances to meet high-grade requirements. Household appliance manufacturers generally use metal materials as decorations to improve product quality. The expansion coefficients are about fifteen times different. When heated, the size of the plastic becomes larger, but the change of the metal ring is small, causing the metal ring to squeeze the plastic and deform it. When the temperature drops, the size of the plastic shrinks, and the plastic part has been squeezed and deformed. , A gap is formed between the metal ring and the plastic, causing the metal ring to loosen. Similarly, when the temperature drops, the size of the metal ring changes slightly, but the shrinkage of the plastic is larger, and a gap is formed between the metal ring and the plastic, causing the metal ring to loosen. take off
Another situation: when the expansion coefficient of the installation body is close to or the same as that of the metal ring, the assembly of the two will also form a gap due to manufacturing tolerances, resulting in loose fixation. The above problems will affect the overall performance of the product

Embodiment Construction
[0024] like Figure 1-8 As shown, the present invention includes: an installation body shell 10 and a decorative metal ring 20 sheathed on the installation body shell 10, and an elimination device is also provided between the installation body shell 10 and the decorative metal ring 20. The compressible part 30 acts on the gap caused by the difference in expansion coefficient between the decorative metal ring 20 and the installation body shell 10 when heated and cooled, and the gap caused by the manufacturing tolerance.
[0025] like Figure 2-5 As shown, the mounting body shell 10 is a soymilk machine head shell, which is composed of a machine head upper shell 11 and a machine head lower shell 12, and the connection between the machine head upper shell 11 and the machine head lower shell 12 is formed. The installation groove 13, the compressible member 30 is installed in the installation groove 13, the decorative metal ring 20 is sleeved on the outer surface of the compressib...

The invention relates to the technical field of household daily life electrical appliances, in particular to a locking device for mounting metal rings of a household electrical appliance. The locking device comprises a mounting body shell, decorative metal rings sleeved on the mounting body shell, and a compressible piece is arranged between the mounting body shell and the decorative metal rings,wherein the compressible piece plays a role in eliminating a clearance caused by different expansion coefficients when the decorative metal rings and the mounting body shell are heated and cooled, and the clearance caused by manufacturing tolerances. Aiming at achieving the aim, the locking device uses a compressible material to eliminate the clearances between the metal rings so as to prevent the metal rings from getting loose.
