The vacuum pump body 5 can be disassembled from the vacuum pump group bracket 1, and the vacuum pump body 5 can be maintained and repaired. However, the vacuum pump body 5 and the vacuum pump group bracket 1 are connected by a number of screws. A special disassembly tool is required to disassemble the vacuum pump body 5 from the vacuum pump group bracket 1. In addition, the screws used to install the vacuum pump body 5 are loosened one by one by using a special tool, which will slow down the disassembly speed. The slow disassembly speed will affect the efficiency of the maintenance personnel in maintaining and repairing the vacuum pump body 5.

The end of the bottom plate 203 close to the contact plate 211 is arc-shaped.When the bottom plate 203 drives the vacuum pump body 5 to contact the connection groove 202, the arc-shaped end of the bottom plate 203 close to the contact plate 211 can improve the connection efficiency between the bottom plate 203 and the connection groove 202, and improve the connection speed between the two. The connecting rod 208 is a titanium alloy rod. The surface of the connecting rod 208 made of titanium alloy is relatively hard, which also makes the surface of the connecting rod 208 made of titanium alloy not easy to deform when used for a long time, and has a long service life;

[0038] In the embodiments of the present invention, please refer to Figure 6 and Figure 7 The auxiliary device 3 includes two connecting plates 31, and the two connecting plates 31 are slidably connected to the vacuum pump group bracket 1. The inner wall thread of the connecting plate 31 is penetrated by two screw rods 32, and the two screw rods 32 are threadedly connected to the vacuum pump group bracket 1. The side of the connecting plate 31 away from the vacuum pump group bracket 1 is fixedly connected to two assembling plates 33, and the sides of the two assembling plates 33 close to each other are fixedly connected to fixing rods 34, and the ends of the two fixing rods 34 close to each other are connected to the same fan blade group 35 through damping rotation. When the vacuum pump body 5 installed on the vacuum pump group bracket 1 works for a long time, the auxiliary device 3 can be used to cool the surface of the vacuum pump body 5, thereby avoiding overheating of the surface of the vacuum pump body 5 and affecting the service life of the vacuum pump body 5. The screw rods The arc surface of 32 is fixedly connected with a connecting ring 36, and the cross section of the connecting ring 36 is annular. When the screw rod 32 rotates in the connecting plate 31 and contacts the connecting plate 31, the connecting ring 36 installed on the screw rod 32 can prevent the screw rod 32 from connecting with the connecting plate 31, so that the connecting ring 36 can prevent the screw rod 32 and the connecting plate 31 from contacting and causing damage. The end of the screw rod 32 away from the connecting ring 36 is fixedly connected with a guide block 37, and the guide block 37 is funnel-shaped.

[0039] The working principle of a vacuum pump group that is easy to maintain provided by the utility model is as follows: when it is necessary to remove the vacuum pump body 5 that has abnormal noise or vibration from the vacuum pump group bracket 1, the contact plate 211 is stretched in the direction of the spring 209 through the connecting rod 208, and the movement of the connecting rod 208 will slide in the adjusting block 207, thereby driving the spring 209 to reel up. At this time, the effect of the spring 209 driving the contact plate 211 to abut against the bottom plate 203 can be released, and the elastic sheet 204 can be pressed in the direction of the bottom plate 203. The movement of the elastic sheet 204 will drive the card block 205 to pop out of the card slot 206. At this time, the fixing effect on the bottom plate 203 can be released, and the bottom plate 203 can be driven to be taken out of the connecting groove 202 through the vacuum pump body 5, so that the vacuum pump body 5 can be removed from the vacuum pump group bracket 1 by the sliding of the bottom plate 203 and the connecting groove 202.

[0040] When the vacuum pump body 5 is used for a long time, the connecting plate 31 is installed on the vacuum pump group bracket 1 through the screw 32, and the fan blade group 35 is rotated by the fixing rod 34. Under the effect of damping, the fan blade group 35 rotated by the fixing rod 34 can be temporarily fixed, and the angle of the fan blade group 35 is aligned with the vacuum pump body 5. Then, the fan blade group 35 is started. The movement of the fan blade group 35 can cool the surface of the vacuum pump body 5, thereby increasing the service life of the vacuum pump body 5.
