[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Reference Figure 1 and Figure 2 Now, the vibration reduction mechanism and air compressor provided by the utility model are described.

[0030] In a first aspect, this embodiment provides a vibration reduction mechanism.

[0031] Example 1

[0032] A vibration damping mechanism includes a vibration damping base 1, a vibration damping rubber ring, and a connecting mechanism 3. The vibration damping base 1 is mounted at the bottom of an air compressor leg, the vibration damping rubber ring 2 is positioned between the vibration damping base and the air compressor leg, and the connecting mechanism 3 is mounted on the air compressor leg. The connecting mechanism 3 passes through the vibration damping rubber ring 2 and secures the vibration damping rubber ring 2 to the air compressor leg.

[0033] The vibration-damping rubber ring 2 is primarily made of rubber. The vibration-damping rubber ring 2 utilizes the elastic deformation of rubber to absorb and reduce vibration and noise, thereby achieving a vibration-damping effect. Rubber material has high elasticity and toughness, effectively absorbing energy and reducing the transmission of vibration and noise. Furthermore, the vibration-damping rubber ring 2 may also be composed of rubber and reinforcing materials, such as fabric and steel wire, to increase its durability and stability. Polyurethane elastic rubber rings and rubber buffer washers are also examples of the vibration-damping rubber ring 2, which similarly utilize the elastic deformation of the material to absorb impact and reduce the transmission of vibration and noise.

[0034] In summary, the main material of the vibration-damping rubber ring 2 is rubber, which is widely used in various occasions requiring vibration reduction and noise reduction due to its excellent elasticity and toughness.

[0035] Compared to existing technologies, the vibration damping mechanism provided by this utility model features a vibration damping base 1 installed at a designated location within the system. Vibration generated by the system is transmitted to the air compressor via the vibration damping mechanism. When the system's vibration is transmitted to the air compressor via the vibration damping base, the vibration amplitude is significantly attenuated by the vibration-damping rubber ring 2, significantly reducing the vibration frequency and minimizing the vibration response to the air compressor. This prevents damage to the compressor or structural loosening caused by vibration.

The sleeve 31 passes through the through hole in the center of the vibration-damping rubber ring 2 and the isolation pad 12. The fixing bolt 32 passes through the sleeve 31 and is threadedly connected to the air compressor leg.

[0040] Optionally, a protective ring 33 is provided at the bottom end of the sleeve 31. When installing the vibration damping mechanism provided in this embodiment, first place the two vibration damping rubber rings on both sides of the isolation pad 12 in the installation cavity 11, and then pass the sleeve 31 from the bottom of the vibration damping base 1 through the vibration damping rubber ring 2 provided below the isolation pad 12, the through hole in the center of the isolation pad 12, and the vibration damping rubber ring 2 provided above the isolation pad 12, and then pass the fixing bolt 32 through the sleeve 31 and fix it in the threaded hole at the bottom of the air compressor leg through threaded engagement, so that the protective ring 33 is pressed against the vibration damping rubber ring below the isolation pad 12, connecting the vibration damping base 1, the vibration damping rubber ring and the air compressor leg together. When the vibration generated by the system is transmitted to the air compressor leg through the vibration damping base 1 and the vibration damping rubber ring 2, the amplitude and frequency of the vibration are greatly reduced, effectively reducing the impact of the vibration on the air compressor, and avoiding damage to the air compressor due to vibration or loose structure.

[0041] Optionally, a fixing seat 4 is provided on the side of the vibration-damping base 1 , and the fixing seat 4 is used to fix the vibration-damping base 1 at a specified position.

[0042] Optionally, a threaded hole is opened on the fixing seat 4, and the fixing seat 4 is fixed at a specified position by bolts.

The connecting mechanism 3 passes through the vibration damping rubber ring 2 and secures the vibration damping rubber ring 2 to the air compressor leg.

[0045] The vibration-damping rubber ring 2 is primarily made of rubber. The vibration-damping rubber ring 2 utilizes the elastic deformation of rubber to absorb and reduce vibration and noise, thereby achieving a vibration-damping effect. Rubber material has high elasticity and toughness, effectively absorbing energy and reducing the transmission of vibration and noise. Furthermore, the vibration-damping rubber ring 2 may also be composed of rubber and reinforcing materials, such as fabric and steel wire, to increase its durability and stability. Polyurethane elastic rubber rings and rubber buffer washers are also examples of the vibration-damping rubber ring 2, which similarly utilize the elastic deformation of the material to absorb impact and reduce the transmission of vibration and noise.

[0046] Compared to existing technologies, the vibration damping mechanism provided by this utility model features a vibration damping base 1 installed at a designated location within the system. Vibration generated by the system is transmitted to the air compressor via the vibration damping mechanism. When the system's vibration is transmitted to the air compressor via the vibration damping base, the vibration amplitude is significantly attenuated by the vibration-damping rubber ring 2, significantly reducing the vibration frequency and minimizing the vibration response to the air compressor. This prevents damage to the compressor or structural loosening caused by vibration.
