Elevator car buffer capable of reducing elevator noise

The utility model belongs to the technical field of elevator shock absorption. The utility model relates to an elevator, in particular to an elevator car buffer for reducing elevator noise. Elevator comprising an elevator car, a plurality of uniformly distributed first springs are fixedly connected to the inner wall of the elevator car; the other ends of the plurality of first springs are connected with a sound insulation box; a bottom plate is fixedly connected to the lower ends of the elevator car and the sound insulation box, four pressure cylinders are installed on the lower end face of the bottom plate, piston rods are installed at the output ends of the four pressure cylinders, the outer side walls of the four piston rods are sleeved with second springs, first shock pads are arrangedat the lower ends of the four piston rods, and a water tank is fixedly connected to the lower end faces of the first shock pads. When the elevator falls or is collided, vibration of the elevator is reduced by compressing the
