[0021] refer to Figure 1 and Figure 3 The front and rear sides of the top of the bottom plate 1 are fixedly connected with sleeves 12 , and both sides inside the sleeve 12 are movably connected with piston racks 13 , and the piston rack 13 is fixedly connected to the slider 10 .

[0022] As a technical optimization scheme of the utility model, through the arrangement of the sleeve 12 and the piston rack 13, for example, the two sliders 10 move away from each other, thereby driving the two piston racks 13 to move away from each other, so that the gas pressure between the two piston racks 13 in the sleeve 12 is reduced, thereby hindering the movement of the piston rack 13, and then hindering the movement of the slider 10, thereby indirectly buffering and reducing vibration of the oil pump body 6.

[0023] refer to Figure 1Magnets 19 are fixedly connected to both sides of the top of the base plate 1 and both sides of the bottom of the support plate 3, and the magnetic poles of adjacent sides of the magnets 19 are the same.

[0024] As a technical optimization solution of the utility model, through the arrangement of the magnets 19, the magnetic poles of the adjacent sides of the upper and lower magnets 19 are the same, so that there is a repulsive force between the upper and lower magnets 19. Therefore, when the movable plate 5 moves downward, the repulsive force between the magnets 19 hinders the movable plate 5 from moving downward, thereby indirectly reducing the vibration of the oil pump body 6.

[0025] refer to Figure 1 The front side and the rear side of the top of the base plate 1 are fixedly connected with dampers 16.

[0026] As a technical optimization solution of the present invention, the high-frequency up-and-down reciprocating shaking of the movable plate 5 can be avoided by setting the damper 16 .

[0027] refer to Figure 1 Both sides of the bottom plate 1 are fixedly connected with mounting plates 17 , and the surface of the mounting plates 17 is provided with mounting openings 18 , and the number of the mounting openings 18 is two.

[0028] As a technical optimization solution of the present invention, by setting the mounting plate 17 and the mounting opening 18, the operator can use bolts to install and fix the device.

[0029] refer to Figure 1 and Figure 4 The top of the support plate 3 is fixedly connected with a limiting ring 15, the limiting ring 15 is movably connected to the rubber plate 9, and the limiting ring 15 is made of stainless steel.

[0030] As a technical optimization solution of the present invention, the rubber plate 9 can be limited by the setting of the limiting ring 15 to prevent the rubber plate 9 from deflecting due to shaking.

[0031] The working principle and use process of the utility model: when in use, the vibration of the oil pump body 6 will drive the movable plate 5 to vibrate. For example, when the movable plate 5 moves downward due to vibration, it will compress the rubber plate 9, and use the elasticity of the rubber plate 9 to indirectly perform the first-level vibration reduction treatment on the oil pump body 6. The downward movement of the movable plate 5 will drive the support plate 3 to move downward, and then drive the connecting rod 11 to move, so that the two sliders 10 move away from each other, and then stretch the tension spring 14. According to the relationship between the action force and the reaction force, the tension spring 14 indirectly exerts an upward force on the oil pump body 6, and then performs the second-level vibration reduction treatment on the oil pump body 6;

[0032] When the rubber sheet 9 is oxidized and hardened, the operator can loosen the nut 7, then remove the nut 7, then move up the movable plate 5, then move up the rubber sheet 9, and then remove the oxidized rubber sheet 9, and then replace it with a new rubber sheet 9. Through the setting of the compression spring 8, when the movable plate 5 is moved up, the elasticity of the compression spring 8 itself can be used to reduce the vibration of the oil pump body 6. At the same time, the compression spring 8 applies elastic force to the nut 7 to prevent the nut 7 from loosening.
