The damping block 1 is internally provided with a clamping channel 11 and a damping channel 12, the damping block 1 is provided with a notch 13, the notch 13 penetrates through two ends of the damping block 1 in the axial direction (the direction B in figure 2) and is communicated with the clamping channel 11, and the damping channel 12 penetrates through the notch 13. The connecting piece 21 is arranged in the vibration reduction channel 12 in a penetrating way, the balance weight 23 is arranged on the connecting piece 21 and is positioned in the vibration reduction channel 12, the elastic piece 22 is connected with the balance weight 23, and the balance weight 23 can reciprocate along the axial direction of the connecting piece 21 so as to press or stretch the elastic piece 22.

According to the vibration damping assembly provided by the embodiment of the utility model, the compressor pipeline 3 can be matched to the clamping channel 11 through the notch 13 on the vibration damping block 1, and then the vibration damping block 1 is locked through the connecting piece 21, so that the reliability of the vibration damping assembly after being installed can be improved. On the other hand, since the balance weight 23 is arranged in the vibration reduction channel 12, when the pipeline 3 vibrates, the vibration reduction assembly can convert the vibration energy of the pipeline 3 into the elastic potential energy of the elastic piece 22 or the kinetic energy of the reciprocating movement of the balance weight 23, so that the vibration reduction of the pipeline 3 is realized. Therefore, the vibration damping assembly of the embodiment of the utility model not only can fix the vibration damping block 1, but also can improve the vibration damping effect of the vibration damping block 1, and has higher reliability in use.

For example, the damper block 1 is generally cylindrical, and the damper block 1 is made of a rubber material, so that the damper effect of the damper assembly can be improved.

In some embodiments, as shown in fig. 3-6, the connector 21 includes a nut 211 and a screw 212, the nut 211 being fitted over an end of the screw 212 and abutting a port of the damper passageway 12. For example, the axial direction of the vibration damping channel 12 is orthogonal to the axial direction of the grip channel 11. When the clamping channel 11 wraps the pipeline 3 of the compressor, the threaded piece 212 can be penetrated into the vibration reduction channel 12 from one end of the vibration reduction channel 12 and locked through the nut 211, so that the vibration reduction block 1 can be firmly fixed on the pipeline 3, the problem of loosening of the vibration reduction block 1 and the pipeline 3 is avoided, the connection is reliable, and the service life is long.

Alternatively, as shown in fig. 3 to 6, the end of the threaded element 212 facing away from the nut 211 can be designed as an end cap 2121, or a nut 211 can likewise be provided. In an embodiment of the utility model, the end of the screw 212 facing away from the nut 211 has an end cap 2121. When the damping block 1 needs to be fixed, the nut 211 can be screwed towards the end cap 2121, so that the gap of the notch 13 is reduced, and the damping block 1 is firmly clamped on the pipeline 3.

In some embodiments, as shown in fig. 5 and 6, the weight 23 is slidably received over the threaded member 212. Specifically, the balance weight 23 is provided with a through hole 231, the screw 212 is in clearance fit with the through hole 231, and the balance weight 23 can move axially relative to the screw 212 under the action of external force. The vibration damping assembly of the embodiment of the utility model can facilitate the processing and manufacturing of the vibration damping balance component 2 by connecting the balance weight 23 and the screw 212 in the above manner, and has higher connection reliability.

Alternatively, as shown in fig. 3 to 6, the elastic member 22 includes a first elastic member 221 and a second elastic member 222, the first elastic member 221 and the second elastic member 222 are respectively sleeved on the connecting member 21, and the balance weight 23 is disposed between the first elastic member 221 and the second elastic member 222. For example, the first elastic member 221 and the second elastic member 222 are each springs. It can be appreciated that one end of the first elastic member 221 abuts against the nut 211, and the other end of the first elastic member 221 abuts against one end of the weight 23. One end of the second elastic member 222 abuts against the end cap 2121, and the other end of the second elastic member 222 abuts against the other end of the weight 23. When the vibration reduction assembly works, the balance weight 23 can vibrate under the driving of the pipeline 3, namely, the balance weight 23 can axially move relative to the threaded piece 212, and the first elastic piece 221 and the second elastic piece 222 are arranged on two sides of the balance weight 23, so that the moving track of the balance weight 23 can be restrained better through the elastic pieces 22 on two sides, and vibration energy of a part of the balance weight 23 can be absorbed, and the purpose of vibration reduction is achieved.

Alternatively, as shown in fig. 5 and 6, the outer peripheral surface of the weight 23 is an arc-shaped surface. For example, the weight 23 has a spherical structure, so that the friction area between the weight 23 and the vibration reduction channel 12 can be reduced, the weight 23 can move more smoothly, and the vibration reduction effect of the vibration reduction assembly can be improved.

In some embodiments, as shown in fig. 1, 2 and 4, at least two damping channels 12 are provided, two damping channels 12 are arranged at intervals along the axial direction of the clamping channel 11, at least two sets of damping balance components 2 are provided, and the two sets of damping balance components 2 are in one-to-one correspondence with the two sets of damping channels 12.

Alternatively, as shown in fig. 1, 2 and 4, the vibration damping block 1 includes a vibration damping body 15 and two thickened portions 16, the outer diameter of the thickened portion 16 being larger than the outer diameter of the vibration damping body 15, the two thickened portions 16 being disposed at both ends of the vibration damping body 15 in the axial direction, respectively, the vibration damping passages 12 being two, the two vibration damping passages 12 being disposed on the two thickened portions 16, respectively. It can be understood that the end positions of the vibration damping block 1 are thicker than the middle position of the vibration damping block 1, so that the stability of the connection of the vibration damping balance part 2 and the vibration damping block 1 can be ensured, and the vibration damping effect is better.

Alternatively, as shown in fig. 3 and 4, the vibration damping block 1 is provided with a mounting notch 14, the mounting notch 14 is provided at the end of the vibration damping channel 12, the mounting notch 14 is provided with a mounting plane 141, and the axial direction of the vibration damping channel 12 is orthogonal to the mounting plane 141. It will be appreciated that the vibration damping channel 12 is provided through the thickened portion 16, and the mounting notch 14 is provided to the outer wall surface of the thickened portion 16. Since the axial direction of the vibration damping channel 12 is orthogonal to the mounting plane 141, the nut 211 and the end cap 2121 can be abutted against the mounting plane 141, thereby reducing the problem that the nut 211 and the screw 212 are loosened due to vibration and improving the reliability of the connection of the nut 211 and the screw 212.

On the other hand, since the balance weight 23 is arranged in the vibration reduction channel 12, when the pipeline 3 vibrates, the vibration reduction assembly can convert the vibration energy of the pipeline 3 into the elastic potential energy of the elastic piece 22 or the kinetic energy of the reciprocating movement of the balance weight 23, so that the vibration reduction of the pipeline 3 is realized. Therefore, the vibration damping assembly of the compressor can fix the vibration damping block 1, can improve the vibration damping effect of the vibration damping block 1, and has higher reliability in use.
