When the bolts are loosened, the connection between the lubricating oil pump and the other pipeline equipment will collide with each other due to the vibration, thereby affecting the noise reduction effect. At the same time, frequent collisions between the connection between the lubricating oil pump and other pipeline equipment will also cause damage to the seals on the lubricating oil pump, thereby causing leakage of lubricating oil, which in turn causes safety hazards.

At the same time, the second connection port 12 is synchronously Drive the first sound insulation cover 5 and the second sound insulation cover 51 to gradually fit together. When the first connecting port 11 and the second connecting port 12 are connected and installed, the first sound insulation cover 5 and the second sound insulation cover 51 are connected and fitted synchronously. Then rotate the sound insulation plate 52 to allow the sound insulation plate 52 to drive the second fixing plate 6 and the second clamping plate 61 to move, so that the second clamping plate 61 is inserted into the positioning plate 62 for clamping and fixing.
