Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

as shown in fig. 1-5, a ball bearing cover plate comprises an outer connecting ring 1, an arc-shaped connecting ring 2 integrally formed with an inner ring of the outer connecting ring 1, and an inner connecting ring 3 integrally formed with an inner ring of the arc-shaped connecting ring 2, wherein a concave surface of the arc-shaped connecting ring 2 is arranged towards one side of a central axis of the outer connecting ring 1, and a convex ring 7 with the same size as the inner connecting ring 3 is integrally formed on one side of the inner connecting ring 3 away from the outer connecting ring 1.

Integrated into one piece has a plurality of bosses 4 that are the ring array and distribute between 2 concave surfaces of arc-shaped connecting ring and 3 top surfaces of in-connection circle, and outer connecting ring 1, arc-shaped connecting ring 2, in-connection circle 3 and a plurality of bosses 4 all adopt stainless steel, and the top surface and the bottom surface of outer connecting ring 1, arc-shaped connecting ring 2, in-connection circle 3 and the outside of a plurality of bosses 4 all coat and have the catalysis nickel phosphorus coating.

As shown in fig. 1 to 7, the outer ring of the outer connecting ring 1 is connected with a circle of outer convex ring 5 made of PVC material by means of bonding with an adhesive, the inner ring of the inner connecting ring 3 is connected with a circle of inner convex ring 6 made of PVC material by means of bonding with an adhesive, the flat sections of the outer convex ring 5 and the inner convex ring 6 are both semicircular, the heights of the outer convex ring 5 and the inner convex ring 6 are respectively half of those of the outer connecting ring 1 and the inner connecting ring 3, and the outer ring of the outer connecting ring 1, the outer surface of the outer convex ring 5, the inner ring of the inner connecting ring 3 and the outer surface of the inner convex ring 6 are all coated with a sealant.

By arranging the outer convex ring 5 and the inner convex ring 6, when the cover plate is embedded into two sides of the bearing and two sides of the bearing are covered, the outer convex ring 5 can be embedded into an outer ring of the bearing, the inner convex ring 6 can be embedded into an inner ring of the bearing, the outer convex ring 5 and the inner convex ring 6 can generate elastic deformation to a certain degree due to the PVC material, and the sealing glue layer coated on the outer surfaces of the outer convex ring 5 and the inner convex ring 6 is driven to generate elastic deformation, and when the cover plate is embedded into two sides of the bearing, the outer convex ring 5, the inner convex ring 6 and the sealing glue layer release elastic potential energy to restore the original state, so that the outer convex ring 5 and the inner convex ring 6 abut against the inner wall of the bearing, thereby reducing the gap between the cover plate and the bearing, preventing dust or liquid from entering the inside of the bearing, achieving a better sealing effect, and by arranging the reinforcing block 4, thereby make this apron itself possess better structural strength, the difficult condition of buckling or warping that takes place, simultaneously because this apron adopts stainless steel to make this apron be difficult for appearing rusty condition, have longer life, this apron still coats outward and has the catalysis nickel phosphorus coating in addition, through setting up the catalysis nickel phosphorus coating, thereby makes it can play better protection effect to the apron, thereby prolongs the life of this apron.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
