The invention discloses a sound insulating and noise reducing device for an elevator car. The sound insulating and noise reducing device is arranged in an elevator box body. A containing cavity is formed between the inner wall and the outer wall of the box body, fixed clamping blocks are arranged on the inner side of the inner wall and/or the outer wall of the box body, and the outer side faces ofmultiple sound insulating assemblies are fixed through the fixed clamping blocks. Each sound insulating assembly comprises a left sound insulating part and a right sound insulating part, wherein theleft sound insulating part and the right sound insulating part are hollow, the adjacent surfaces of the left sound insulating part and the right sound insulating part are fixed through a fixing assembly, the fixing assembly comprises a slot and an inserting rod, the left sound insulating part and the right sound insulating part are filled with sound absorbing materials, fixed clamping grooves cooperating with the fixed clamping blocks are formed in the outer sides of the left sound insulating part and the right sound insulating part, and supporting rods are arranged in the left sound insulating part and the right sound insulating part. The containing cavity is formed between the inner wall and the outer wall of the box body, the multiple sound insulating assemblies are arranged in the containing cavity, the multiple sound insulating assemblies can be connected and fixed end to end according to the actual requirements, the sound insulating assemblies are filled with the sound absorbingmaterials, the effect of noise reducing is achieved, and the sound insulating and noise reducing device is simple in structure, good in noise reducing effect and high in practicality.
