Description of reference numerals: the compressor comprises a box body side plate 1, a compressor 2, a compressor bin 3, a compressor bottom plate 4, a first damping gasket 5, a first fastening bolt 6, a nut sleeve 9 and a side plate flanging 10.
Detailed Description
The technical solution is described in detail with reference to specific embodiments below.
As shown in fig. 1-2, a vibration damping structure of a compressor bottom plate comprises a compressor bottom plate 4 and a box body side plate 1 of a refrigerator, wherein the compressor bottom plate 4 is installed at the bottom of the box body side plate 1, the box body side plate is provided with a side plate flange 10, a first flange through hole is formed on the side plate flange, the compressor bottom plate 4 is provided with a first bottom plate through hole corresponding to the first flange through hole, and a first fastening bolt 6 penetrates through the first flange through hole and the first bottom plate through hole and fixes the compressor bottom plate 4 on the side plate flange 10; first bottom plate through-hole nestification has first damping packing ring 5, first damping packing ring establishes first contact terminal surface, and is perpendicular first contact terminal surface link up and is provided with first bolt hole, a fastening bolt passes first bolt hole, first contact terminal surface elasticity is contradicted on curb plate turn-ups 10.
