[0005] Preferably, one side of the sealing ring is provided with a groove matched with the protrusion on the outer side of the lower base, and the other side is provided with a sealing lip, and the inner side of the upper base is provided with an annular groove for accommodating the sealing lip.

[0006] Preferably, the sealing lip is of a wave-shaped structure.

[0007] Preferably, sleeves are connected to the two ends of the upper support plate and the lower support plate by screws two respectively.

[0008] Preferably, the surfaces of the upper support plate and the spherical crown lining plate are cladded with a stainless steel layer by laser.

[0009] The utility model has the following advantages:

[0010] In use, the groove on one side of the sealing ring can quickly position the sealing ring on the outer side of the lower base, the wave-shaped sealing lip on the other side of the sealing ring is located in the annular groove on the inner side of the upper base, and the upper base and the lower base are fixed by a screw, so that external dust cannot enter the spherical crown lining plate, the spherical surface sliding plate and the flat surface sliding plate, and the upper support plate and the spherical crown lining plate have improved corrosion resistance by cladding with a stainless steel layer.
