[0006] Preferably, the disassembly and assembly component includes a concave plate, four of the concave plates are connected to one side of the refrigerator back panel body, the outer wall of the noise reduction box is connected with docking plates that match the concave plates, one side of the concave plate is connected with a screw, one end of the screw passes through the docking plate, and one end of the screw is threadedly connected to a threaded ring.

[0007] Preferably, one side of the sound absorbing plate is connected to a plurality of openings.

[0008] Preferably, a sound insulation felt is connected to one side of the outer wall of the noise reduction box, and curved surfaces are provided at the corners of the noise reduction box.

[0009] Preferably, polyurethane foam is filled between the noise reduction box and the through groove.

[0010] Preferably, the outer wall of the threaded ring is provided with a plurality of arc grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The utility model provides a noise reduction component, which absorbs the noise inside the refrigerator through the sound-absorbing board, and allows part of the noise to enter the interior of the noise reduction box, so that the pores and fine fibers on the rock wool board scatter and absorb the sound waves. Then, the convex and concave wave structure of the rubber-plastic egg cotton absorbs the sound waves again, thereby achieving the effect of the refrigerator back panel reducing the noise inside the refrigerator, effectively avoiding the refrigerator from interfering with people's rest and sleep during operation, indirectly improving people's quality of life, and being beneficial to protecting people's physical and mental health.

[0013] (2) The utility model provides a disassembly and assembly component. When the noise reduction box and the refrigerator back panel body need to be transported, the threaded ring is screwed to move the threaded ring on the screw rod and disengage it from the screw rod, thereby releasing the limit of the docking plate on the concave plate. Thereafter, the noise reduction box is pulled outward to disengage the docking plate from the screw rod, thereby separating the noise reduction box from the refrigerator back panel body, improving the disassembly and assembly efficiency of the noise reduction box, facilitating the separate transportation or replacement of the noise reduction box, and improving the convenience of the refrigerator back panel.
