Sound insulation structure of elevator car

The utility model provides an elevator car sound insulation structure, which relates to the technical field of elevator cars, and comprises a support frame body, a fixed plate on the upper surface of the support frame body is connected with a support keel, the upper surface of the support keel is fixedly connected with a fixed sealing cover plate, and the bottom surface of the fixed sealing cover plate is fixedly connected with shock absorption short columns which are distributed at equal intervals. According to the device, the first heat insulation layer, the first sound insulation layer, the second sound insulation layer and other components are arranged, and the first heat insulation layer and the first sound insulation layer component are matched with the second sound insulation layer component, so that the first sound insulation layer component can weaken sound through a flexible high-density material; therefore, the device can absorb sound through the second sound insulation layer, and the problems that
