At the same time, rubber pads of the same specifications also have a uniform thickness. During installation and use, rubber pads of different thicknesses need to be adapted.

[0004] Therefore, it is necessary to invent a rubber pad structure resistant to acid and alkali corrosion to solve the above problems. Utility Model Content

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model is provided with a magnetic component, which can, on the one hand, reduce the force on the rubber pad body through the magnetic component, and on the other hand, when the surface of the rubber pad body is worn, resulting in reduced connectivity between the rubber pad body and other parts, the repulsive force in the magnetic component can restore the rubber pad body to its initial state in time, thereby restoring the connectivity between the rubber pad body and other parts, and increasing the service life of the rubber pad body. At the same time, the rubber pad body is used by being sleeved on a cylindrical part, and after damage is caused between the circular hole of the rubber pad body and the cylindrical part, the connectivity between the rubber pad body and the cylindrical part will also be reduced.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-Figure 3 As shown, a rubber pad structure resistant to acid and alkali corrosion includes a rubber pad body 1, the interior of the rubber pad body 1 is fixedly connected with a rubber partition 15, and the rubber partition 15 divides the interior of the rubber pad body 1 into two circular grooves 5;

[0022] The rubber pad body 1 is made of rubber and has elasticity. The rubber is fluororubber and has excellent acid and alkali corrosion resistance, so that the rubber pad body 1 will not be corroded by acids and alkalis.

[0023] A magnetic assembly is arranged inside the circular groove 5, and the magnetic assembly includes a first magnetic block 6. There are multiple first magnetic blocks 6, and the multiple first magnetic blocks 6 are fixedly connected in the circular groove 5. The first magnetic blocks 6 in the two circular grooves 5 repel each other. A rubber ring 7 is arranged inside the circular groove 5, and the rubber ring 7 is fixedly connected to the rubber diaphragm 15. An arc groove 12 is opened inside the rubber ring 7. A plurality of second magnetic blocks 13 and a third magnetic block 14 are arranged inside the arc groove 12. The plurality of second magnetic blocks 13 and the third magnetic block 14 are fixedly connected in the arc groove 12, and the second magnetic blocks 13 and the third magnetic blocks 14 repel each other. The plurality of second magnetic blocks 13 and the third magnetic blocks 14 are distributed in a circular array.

[0024] The utility model is provided with a magnetic component, which can, on the one hand, reduce the force on the rubber pad body 1 through the magnetic component, and on the other hand, when the surface of the rubber pad body 1 is worn, resulting in reduced connectivity between the rubber pad body 1 and other parts, the repulsive force in the magnetic component can restore the rubber pad body 1 to its initial state in time, thereby restoring the connectivity between the rubber pad body 1 and other parts, and increasing the service life of the rubber pad body 1. At the same time, the rubber pad body 1 is used by being sleeved on a cylindrical part, and after damage is caused between the circular hole 2 of the rubber pad body 1 and the cylindrical part, the connectivity between the rubber pad body 1 and the cylindrical part will also be reduced. Therefore, when the circular hole 2 is worn, the repulsive force between the second magnetic block 13 and the third magnetic block 14 can be used to make the circular hole still fit tightly with the cylindrical part, thereby increasing the service life of the rubber pad body 1.

[0025] A circular hole 2 is provided inside the rubber ring 7, and a buffer assembly is arranged at the outer ring of the rubber ring 7. The buffer assembly includes a first fixed block 8. Two first fixed blocks 8 are arranged, and the two first fixed blocks 8 are respectively fixedly connected to the rubber ring 7.

[0028] The sealing plate 4 plays a role of sealing, and the gas pipe 3 plays a role of conveying gas.

[0029] Furthermore, since the rubber pad body 1 is made of rubber material and has a certain ductility, during the installation process, the thickness of the corresponding rubber pad body 1 is of uniform specification, and the installation of parts requires rubber pad bodies 1 of different thicknesses to adapt. Therefore, an inflation component is provided on the rubber pad body 1, and the rubber pad body 1 can be partially inflated by the inflation component to increase the thickness of the rubber pad body 1, so that the rubber pad body 1 has diversity and can be suitable for the installation of different parts. At the same time, after installation, the thickness of the rubber pad body 1 can be fine-tuned by inflation to make the connection between the rubber pad body 1 and other parts tighter.
