[0031] Reference Figure 1-Figure 3 The top of the mounting shell 10 is fixedly connected with a fixing block 14, and the top of the connecting shell 11 is fixedly connected with a mounting block 15. The inner wall of the mounting block 15 is slidably connected with a limiting plate 16. Two groups of limiting plates 16 are provided. The two groups of limiting plates 16 are elastically connected by a movable spring 17. One end of the movable spring 17 is connected to the upper limiting plate 16, and the other end of the movable spring 17 is connected to the lower limiting plate 16. When the limiting plates 16 are brought close to each other, the movable spring 17 is compressed. When resetting, the movable spring is used to 17 is reset with the limit plate 16, the inner wall of the mounting block 15 is fixedly connected with a support tube 18, the support tube 18 mainly guides the limit plate 16, and allows the limit plate 16 to move vertically without offsetting the moving track, the fixed block 14 contacts the outer wall of the mounting block 15, the fixed block 14 matches the mounting block 15, and after the mounting shell 10 and the connecting shell 11 are spliced, the fixed block 14 contacts the mounting block 15, and the limit plate 16 is clamped with the inner wall of the fixed block 14, such as Figure 5 As shown, a slot corresponding to the limit plate 16 is provided on the fixed block 14, so that the limit plate 16 can be snapped into the slot to connect the fixed block 14 and the mounting block 15. The limit plate 16 is slidably connected to the outer wall of the support tube 18, and the mounting shell 10 is in contact with the side of the connecting shell 11.

[0032] Reference Figure 1-Figure 3 The top of the bottom plate 1 is fixedly connected to one end of the supporting spring 4. When the movable plate 5 moves downward, the supporting spring 4 will be compressed. When resetting, the elastic force of the supporting spring 4 is used to reset. The other end of the supporting spring 4 is fixedly connected to the bottom end of the movable plate 5. The top of the slider 6 is hinged to one end of the hinged rod 8. Since the length of the hinged rod 8 is certain, when the movable plate 5 moves downward, the hinged rods 8 will be separated from each other. On the contrary, when the movable plate 5 moves upward, the hinged rods 8 will be brought closer to each other. The other end of the hinged rod 8 is hinged to the bottom end of the movable plate 5. The slider 6 is slidably connected to the outer wall of the guide tube 9. The piston tube 3 is fixedly connected to the bottom end of the movable plate 5. The driving mechanism includes a circulating pump 13. The circulating pump 13 is a device for circulating liquid or gas from one place to another. It is a prior art and will not be described in detail here. The circulating pump 13 can be detachably mounted on the top of the movable plate 5. The circulating pump 13 is mounted and disassembled with the movable plate 5 by bolts.

[0033] Working principle: First, when the circulating pump 13 generates vibration and noise, the sound-absorbing cotton 12 in the mounting shell 10 and the connecting shell 11 will absorb the noise, and the vibration generated will cause the movable plate 5 to move downward. When the movable plate 5 moves downward, it will move the piston tube 3 downward. Since there is air in the sleeve 2, the piston tube 3 will compress the air in the sleeve 2 to generate a certain resistance to reduce the vibration. At the same time, the support spring 4 will be compressed and the reverse elastic force of the support spring 4 will be used to alleviate part of the vibration. The movable plate 5 moves downward and will move one end of the hinged rod 8 downward, allowing the other end of the hinged rod 8 to separate from the slider 6, which will cause the slider 6 to stretch the reset spring 7 to a certain length. The friction generated by the moving slider 6 and the inner wall of the bottom plate 1 and the reverse elastic force of the reset spring 7 will alleviate part of the vibration and reduce the noise generated by the vibration of the circulating pump 13.

[0034] The entire movable plate 5 moves upward and is reset upward by the reverse elastic force of the supporting spring 4, allowing the movable plate 5 to move upward with one end of the hinged rod 8, and the two sets of sliders 6 move closer to each other by the elastic force of the reset spring 7. When the movable plate 5 moves upward with the piston tube 3, the air will re-enter the sleeve 2 from the circular hole of the sleeve 2. When the circulating pump 13 vibrates, noise reduction will be performed according to the first and second stage methods.

[0035] When it is necessary to disassemble and assemble the mounting shell 10 and the connecting shell 11, it is only necessary to press the limit plate 16 to bring the limit plates 16 closer to each other and compress the movable spring 17 to separate the limit plate 16 from the inner wall of the fixed block 14, and then move to separate the mounting shell 10 and the fixed block 14 from the connecting shell 11 and the mounting block 15. During installation, it is only necessary to bring the mounting shell 10 and the connecting shell 11 closer to each other, splice the mounting shell 10 and the connecting shell 11, and splice the mounting block 15 and the fixed block 14, and press the limit plate 16 in advance to make the inner wall grooves of the limit plate 16 and the fixed block 14 overlap, then release the limit plate 16 and use the reverse elastic force of the movable spring 17 to reset the limit plate 16, so that the limit plate 16 and the fixed block 14 are engaged, and the mounting shell 10 and the connecting shell 11 can be quickly disassembled and assembled to maintain the circulating pump 13.
