[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example

[0020] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention proposes a vacuum pump vibration damping structure, including a vacuum pump body 1 and a support plate 2. The vacuum pump body 1 is installed on the top of the support plate 2. A base plate 3 is provided below the support plate 2. First damping telescopic rods 4 are fixed at the four corners of the top of the base plate 3. The top ends of the first damping telescopic rods 4 are fixedly connected to the bottom of the support plate 2. First springs 5 ​​are sleeved on the surface of the first damping telescopic rods 4. The two ends of the first springs 5 ​​are fixedly connected to the top of the base plate 3 and the bottom of the support plate 2, respectively. Two connecting rods 6 are symmetrically rotatably connected to the bottom of the support plate 2 by pins. The bottom ends of the two connecting rods 6 are rotatably connected to the first racks 7 by pins. A slide plate 8 is fixed to one end of each first rack 7. Two second racks 8 are symmetrically fixed to one side wall of each slide plate 8. The base plate 3 has two second damping telescopic rods 9, one end of which is fixed to a first fixing plate 10. The first fixing plate 10 is fixed to the top of the base plate 3. Each second damping telescopic rod 9 has a second spring 11 fitted onto its surface. The two ends of the second spring 11 are fixedly connected to one side wall of the adjacent sliding plate 8 and one side wall of the first fixing plate 10, respectively. Two support plates 12 are symmetrically fixed at both ends of the top of the base plate 3. A rotating shaft 13 is rotatably connected between the two support plates 12 via a bearing. A gear 14, which meshes with the first rack 7, is fitted onto the surface of the rotating shaft 13. A second fixing plate 15 is fixed to the middle of the upper surface of the base plate 3. Two third damping telescopic rods 16 are symmetrically fixed to the two side walls of the second fixing plate 15. One end of each of the two corresponding third damping telescopic rods 16... A connecting plate 17 is fixed at one end. A third spring 18 is fitted onto the surface of the third damping telescopic rod 16. The two ends of the third spring 18 are fixedly connected to one side wall of the adjacent second fixed plate 15 and one side wall of the connecting plate 17, respectively. A second rack 19 is fixed to the other side wall of the connecting plate 17. The second rack 19 meshes with the corresponding gear 14. When the vacuum pump body 1 operates, it drives the support plate 2 to move vertically. When the support plate 2 moves downwards, it compresses the first damping telescopic rod 4 and the first spring 5. Under the combined action of the first damping telescopic rod 4 and the first spring 5, a good shock absorption and buffering effect can be achieved. When the support plate 2 moves downwards, it also drives the two connecting rods 6 to move. The connecting rods 6 drive the corresponding first rack 7 to move outwards. The first rack 7 will drive the corresponding slide plate 8 to move outward, thereby squeezing the second damping telescopic rod 9 and the second spring 11. Under the combined action of the second damping telescopic rod 9 and the second spring 11, the shock absorption and buffering effect can be further improved. When the first rack 7 moves outward, it will drive the corresponding gear 14 to rotate. The gear 14 can drive the corresponding second rack 19 to move inward. The second rack 19 can drive the corresponding connecting plate 17 to move inward. The connecting plate 17 will squeeze the corresponding third damping telescopic rod 16 and the third spring 18. Under the combined action of the third damping telescopic rod 16 and the third spring 18, the shock absorption and buffering effect can be further improved, so the noise generated by the vibration of the vacuum pump body 1 during operation can be reduced.

[0021] like Figure 1 As shown, in some embodiments, the surface of the slide plate 8 is provided with a clearance opening 20 for the second rack plate 19, so that when the second rack 19 moves outward, it can smoothly pass through the corresponding slide plate 8.

[0022] like Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the base plate 3 is fixed with an anti-slip rubber pad 21 in order to better play the role of shock absorption and cushioning, thereby reducing the noise generated by vibration during operation.

[0023] like Figure 1 As shown, in some embodiments, the vacuum pump body 1 is fixed to the top of the support plate 2 by bolts in order to facilitate the installation of the vacuum pump body 1 on the support plate 2.

[0024] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. 。
