In the invention, a base plate through hole 12 is formed in the center of the inner wall of the bottom of the radial positioning groove 11, the compressor positioning bolt 3 penetrates through the base plate through hole 12 and extends to the lower part of the base plate 1, and the bottom end of the compressor positioning bolt 3 extends to the lower part of the base plate 1, so that the compressor positioning bolt 3 can be conveniently detached in the later period.

In the invention, the compressor positioning bolt 3 comprises a stud bolt 31, a positioning shaft shoulder 32 and a dismounting head 33, the positioning shaft shoulder 32 is fixed at the central position of the stud bolt 31, the dismounting head 33 is fixedly arranged at the bottom of the stud bolt 31, the compressor is conveniently fixed on the base through the arrangement of the stud bolt 31, the positioning shaft shoulder 32 and the dismounting head 33, and the fixing structure is stable and the dismounting is convenient.

In the invention, the positioning shaft shoulder 32 is of a circular truncated cone structure, and the compressor vibration reduction rubber pad is sleeved on the positioning shaft shoulder 32, so that the position of the compressor vibration reduction rubber pad is convenient to limit and is always positioned between the chassis and the compressor.

In the invention, the two ends of the stud bolt 31 are both provided with external threads, the two ends of the stud bolt 31 are both provided with the nut 5 with the gasket in a threaded manner, and the external threads of the stud bolt 31 are arranged, so that the nut 5 with the gasket can be conveniently mounted in a threaded manner.

In the invention, the bottom of the upper nut 5 with the pad is contacted with the top of the connecting block 21, the top of the lower nut 5 with the pad is contacted with the bottom of the chassis 1, and the connecting block 21 and the chassis can be firmly connected together without loosening by the contact of the nut 5 with the pad and the connecting block 21 with the chassis 1.

According to the invention, the nut 5 with the pad comprises the nut and the washer, the washer is fixed on the nut, and the nut can be more stably and firmly installed through the arrangement of the washer.

In the invention, the cavity is formed in the vibration reduction rubber pad of the compressor, the positioning shaft shoulder 32 is positioned in the cavity, and the positioning shaft shoulder 32 is conveniently arranged through the cavity to limit the position of the vibration reduction rubber pad of the compressor so as to be always positioned between the chassis and the compressor.

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.

In another state, when the air conditioner is used (before the air conditioner is installed after being purchased by a user) and the packaged air conditioner is disassembled, the nut with the gasket at the lower end of the positioning bolt can be disassembled by using a tool such as a wrench, the disassembling structure is specially designed at the lower end of the positioning bolt of the compressor, the nut is equivalent to a four-corner or hexagonal column, the lower end of the positioning bolt is fixed by using an inner four-corner hexagonal wrench, and the nut with the gasket at the lower end can be easily disassembled by using the wrench.

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.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
