In the invention, the dismounting head 33 is a hexagonal column, so that the dismounting is conveniently carried out by a hexagonal wrench.
A vibration-damping rubber pad comprises the compressor vibration-damping rubber pad 4.
According to the invention, a compressor positioning bolt passes through a middle cavity of a vibration-damping rubber pad and is assembled together by virtue of a positioning shaft shoulder on the compressor positioning bolt, then the compressor positioning bolt is placed in a radial positioning groove of a chassis, one end of the compressor positioning bolt penetrates out of a through hole of the chassis, then one side of a dismounting head is screwed by a nut with a pad, so that the positioning bolt and the vibration-damping rubber pad are fixed on the chassis, then the compressor is placed on the vibration-damping rubber pad, and then the upper end of the positioning bolt is positioned by the nut with the pad;
the compressor positioning bolt is in a mode that both ends of the compressor positioning bolt are threaded and the nuts with the cushions are matched, so that rigid connection and non-rigid connection are formed between the compressor positioning bolt and the chassis, when the air conditioner is subjected to a drop test and is transported, the nuts with the cushions on the upper portion and the lower portion are in a screwed state, the nuts at the lower end are screwed, and the mode is equivalent to a mode that the compressor positioning bolt and the chassis are integrally molded or welded.

After the nut with the pad at the lower end is disassembled, the non-rigid connection among the compressor, the compressor positioning bolt and the chassis is really realized relative to the connection mode of the compressor positioning bolt and the chassis. Meanwhile, after the lower end of the positioning bolt of the compressor with the gasket is disassembled, the radial direction of the compressor is not limited, and in the shutdown process of the air conditioner, large vibration can be generated, so that large stress can be generated on the pipeline in the process, and the problem of stress fatigue cracking can occur on the pipeline when the air conditioner is stopped and started for many times. In view of the above, the inner diameter of the positioning groove of the radial positioning groove is slightly larger than the outer diameter of the vibration damping rubber pad. Then, after the nut at the lower end of the compressor positioning bolt is removed, the radial vibration amplitude of the compressor during the shutdown process is greatly reduced. Thereby avoiding the situation that the pipeline is subjected to large stress.
The screw thread design of both ends of the compressor positioning bolt designed by the invention is matched with the nut with the pad, so that the rigid connection and the real non-rigid connection between the compressor and the chassis can be realized, the requirements of an air conditioner on the fixation of the compressor in the falling test and the actual transportation process can be met, the aim of reducing the vibration and the noise of the whole machine in the working process of the air conditioner can be fulfilled, the influence on users by the vibration and the noise of the split air conditioner is slightly smaller, but the noise can be effectively reduced for the air conditioners with the compressor, such as a mobile air conditioner, a dehumidifier and the like, which are placed indoors for working, and the invention has obvious effects on the performance of products and the improvement of user experience.
