Description

Technical Field

[0001] The utility model relates to the field of air-conditioning equipment, in particular to a compressor vibration-damping foot pad with adjustable hardness. Background Art

[0002] The compressor is the power core of the refrigeration system, providing power for the refrigeration system, and is also the source of vibration and noise in the air-conditioning outdoor unit system. The compressor body will cause vibration and noise problems, and the vibration of the compressor will be transmitted to the pipe system connected to it. The structure of the variable frequency air-conditioning outdoor unit pipe system is complex and has low flexibility. It is easily stimulated by the vibration of the compressor and causes pipe vibration and noise problems. In order to prevent the compressor vibration from being directly transmitted to the sheet metal structure of the outdoor unit, the compressor mounting feet are vibration-damping rubber structures, and the elasticity of the rubber feet is used to absorb and eliminate vibration. Different compressor systems have different requirements for the characteristics of the rubber feet. In the test process for the rubber characteristics, the parameters of the vibration-damping foot pads are obtained, and then the vibration and noise parameters of the compressor are tested, so as to obtain the correlation between the parameters of the vibration-damping foot pads and the vibration and noise parameters of the compressor. However, in actual experiments, it is necessary to replace the vibration-damping foot pads with different hardness parameters for experiments. The disassembly and assembly process is relatively cumbersome and the work efficiency is low. Utility Model Content

Through the fixing effect of the mounting blind hole and the mounting bolt, the foot pad body can be stably positioned in the air conditioner to ensure the stability of the compressor connection.

[0007] Furthermore, the shape of the inflation cavity is the same as that of the foot pad body, and the foot pad body and the inflation cavity form a shell, and the wall thickness of the shell is the same everywhere, which can ensure that the overall hardness characteristics of the foot pad body are balanced after inflation, so that the hardness adjustment effect of the foot pad body is better.

[0008] Furthermore, the sealing member is a sealing cover that is clamped to the outer end of the inflation port, and the sealing cover can ensure that the inflation port does not leak and ensure the sealing of the inflation cavity.

[0009] Furthermore, the inflation port is provided on the top wall of the foot pad body, and the inflation port is provided on the top wall of the foot pad body, which is convenient for inflation using an inflation device.

[0010] Furthermore, the foot pad body is cylindrical, and the upper outer diameter of the foot pad body is smaller than the lower outer diameter, so that the support effect of the foot pad body is better.

[0011] The beneficial effects of the utility model are:

[0012] By providing an inflation cavity in the foot pad body, the air pressure in the inflation cavity can be adjusted through inflation and exhaust operations, thereby adjusting the hardness of the foot pad body.

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] according to Figure 1-Figure 3As shown, the embodiment of the present application proposes a vibration-damping foot pad for a compressor 100 with adjustable hardness, comprising a foot pad body 1, a mounting portion 2 for fixing the foot pad body 1 is provided at the lower portion of the foot pad body 1, a sealed inflation cavity 4 is provided inside the foot pad body 1, the foot pad body 1 is provided with an inflation port 5 for inflating the inflation cavity 4 and a sealing member 3 adapted to the inflation port 5; the foot pad body 1 is made of rubber, and the foot pad body 1 is specifically provided with a connecting portion, which is used to connect to the support frame of the compressor 100, and the compressor 1 00 is provided with three supporting legs, and three foot pad bodies 1 are correspondingly provided, and the foot pad body 1 can achieve a stable supporting effect on the compressor 100, and the foot pad body 1 is made of rubber material, has a certain elasticity, can buffer and absorb the vibration generated when the compressor 100 is working, so as to achieve the effect of vibration reduction and noise reduction, and the hardness and rigidity of the foot pad body 1 can be adjusted by setting the inflation port 5 and the inflation cavity 4, and the structure is simple, and the adjustment process is carried out by adjusting the air pressure through the inflation equipment, and the adjustment process is relatively accurate and convenient to control.

[0019] It should be noted that the foot pad body 1 needs to be stably positioned in the air-conditioning case. In order to improve the positioning stability of the foot pad body 1, the above-mentioned mounting portion 2 includes a mounting blind hole 201 opened at the bottom of the above-mentioned foot pad body 1. The above-mentioned mounting blind hole 201 is not connected to the above-mentioned inflation chamber 4. The above-mentioned mounting blind hole 201 is provided with a mounting bolt 202 extending to the bottom end of the above-mentioned foot pad body 1. Specifically, the bottom end of the above-mentioned mounting bolt 202 is fixed to the internal connecting plate of the air conditioner by welding or other fixing methods, and the top end of the mounting bolt 202 extends into the mounting blind hole 201, and the mounting blind hole 201 may be provided with a thread or no thread.

The specific depth size is compatible with the size of the installation bolt 202 to ensure the stability of the connection. The above-mentioned installation blind hole 201 is not connected to the inflation chamber 4 to ensure the air tightness of the inflation chamber 4.

[0021] Moreover, in a specific implementation manner, the provision of the inflation chamber 4 may cause uneven wall thickness of the foot pad body 1, resulting in differences in the air pressure and hardness parameters of each surface of the foot pad body 1 after inflation, which may further affect the actual hardness parameters of the foot pad body 1 during the test.

[0023] The inflation port 5 may be disposed on the side wall of the foot pad body 1 or on the top of the foot pad body 1, so as to facilitate connection operation when inflating through an inflation device.

[0024] Regarding the shape of the foot pad body 1, in some embodiments, the foot pad body 1 is cylindrical, and the upper outer diameter of the foot pad body 1 is smaller than the lower outer diameter.
