[0019] By arranging the double-eye hole on the L-shaped leg and the connecting part that can be sleeved into the double-eye hole on the shock-absorbing pad, the shock-absorbing pad can adjust the installation direction as needed. This design enables the same set of shock-absorbing legs to adapt to compressors with different cylinder wall thicknesses, without the need to design different legs for each wall thickness, greatly improving the adaptability and flexibility of the product.

[0020] Since the shock-absorbing leg can be applied to compressors with multiple cylinder wall thicknesses, the specification types of the L-shaped leg are greatly reduced. This not only simplifies production and inventory management, but also reduces manufacturing and procurement costs, which is particularly advantageous for large-scale production.

[0021] The design of the damping pad, especially the boss and through-hole structure on it, helps to absorb and disperse the vibrations generated during the operation of the compressor, thereby improving the stability and durability of the entire system. The connection part of the double-eye structure further enhances this damping effect, as it allows for more precise adjustment of the position and angle of the damping pad for optimal damping effect.

During installation, simply choose the appropriate installation direction according to the cylinder wall thickness of the compressor, and align the marks, greatly simplifying the installation process and improving installation efficiency and accuracy.

[0023] In summary, this technical solution achieves wide adaptability of the damping foot to compressors with different cylinder wall thicknesses through innovative design and clever assembly methods, while improving damping effect, installation efficiency, reliability, and safety, and optimizing space utilization. These technical effects collectively constitute the core value of this technical solution, bringing significant benefits to manufacturers and users of compressors and air conditioners.

However, the embodiment achieves the same specification of L feet and vibration pads to adapt to different cylinder wall thicknesses through the double-eye structure and specific assembly method, thereby significantly reducing the types of feet, and reducing the cost of production and management.

[0056] L feet and vibration pads are provided with marking lines or triangular marks, which provide clear guidance for installation. During installation, only the appropriate installation direction is selected according to the cylinder wall thickness, and the marks are aligned, which greatly improves the installation efficiency and accuracy.

[0057] The back plate of the L foot is connected to the compressor cylinder peripheral wall by projection welding, which has high strength and stability, can effectively support the compressor and prevent it from shaking. At the same time, the design of the boss and the connecting part of the vibration pad also enhances the stability of the entire structure, so that the compressor runs more smoothly.

[0058] The compact design of L feet and vibration pads allows them to efficiently utilize space, especially in the limited space inside the air conditioner. This design helps to reduce the volume and weight of the entire system, improve energy efficiency and environmental performance.

[0059] Through precise design and manufacturing, L feet and vibration pads can firmly connect the compressor and the air conditioner bottom plate, and maintain stable connection in long-term operation and vibration environment. This helps to improve the reliability and durability of the entire air conditioning system, reduces failures and accidents caused by loose or failed connections.
