DETAILED DESCRIPTION

[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the attached Figure 1-9 Shown in.

[0029] In the description of this specification, the description with reference to the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0030] The present application embodiment discloses a corrosion-resistant ceramic bearing structure, referring to Figure 1 , including an outer bearing 1 and an inner bearing 2, the arc surface of the inner bearing 2 is slidably connected with a fixing block 5, and two fixing blocks 5 are provided. A ball 4 is installed between the two fixing blocks 5, a main fixing frame 7 and a sub-fixing frame 8 are clamped on the surface of the outer bearing 1, an installation space is formed between the main fixing frame 7 and the sub-fixing frame 8, the outer bearing 1 is clamped in the installation control space, and a sponge ring 11 is clamped on the inner wall of the main fixing frame 7 and the sub-fixing frame 8.

[0031] The surfaces of the main fixing frame 7 and the auxiliary fixing frame 8 are fixedly connected with 5 limit arc blocks 18. The sponge ring 11, the main fixing frame 7, the auxiliary fixing frame 8, the outer bearing 1 and the inner bearing 2 are all provided with screw holes 6. The inner wall of the screw hole 6 is threadedly connected with a bolt rod 10. After the screw hole 6 and the bolt rod 10 are threadedly connected, the main fixing frame 7 and the auxiliary fixing frame 8 can be fixed, and it is convenient to fix them on the surface of the ceramic bearing. At the same time, the sponge ring 11 can absorb sweat on the hands of personnel or liquid flowing into the ceramic bearing from the outside, preventing these liquids from directly contacting the small cracks on the surface of the ceramic bearing and causing corrosion to the ceramic bearing. Figure 3 In order to facilitate the threaded cooperation between the bolt rod 10 and the screw hole 6, a rotating block 16 is fixedly connected to the end surface of the bolt rod 10, and the rotating block 16 is in the shape of a four-cornered plum blossom handle.

[0032] The outer arc surface of the outer bearing 1 is evenly coated with an anti-corrosion layer 3, wherein the anti-corrosion layer 3 can be a galvanized layer, a hot-dip aluminum-zinc layer, etc. The anti-corrosion layer 3 can further increase the corrosion resistance of the ceramic bearing surface.

[0033] A support frame 9 is fixedly connected to the surface of the main fixed frame 7 and the auxiliary fixed frame 8. The support frame 9 includes an integrally formed circular frame and four connecting frames interconnected with the circular frame. The support frame 9 can support the outer side of the sponge ring 11 to improve the stability of the connection between the sponge ring 11 and the main fixed frame 7 and the auxiliary fixed frame 8.

[0034] like Figures 4 to 9As shown, a film 12 is installed on the inner wall of the sponge ring 11, and the film 12 is closely attached to the inner wall of the sponge ring. At the same time, the internal film 12 can prevent external dust from entering the ceramic bearing through the holes on the surface of the sponge ring 11, thereby playing a certain protective role for the ceramic bearing.

[0035] The inner wall of the limiting arc block 18 is fixedly connected with a plurality of thorns 17, wherein the thorns 17 include an integrally formed base and a quasi-pointed protrusion structure. The plurality of thorns 17 are evenly distributed on the inner side of the limiting arc block 18, and the quasi-pointed protrusion structure can penetrate into the interior of the sponge ring 11, thereby increasing the points of force of the sponge ring 11 on the surface of the main fixing frame 7 and the auxiliary fixing frame 8.

[0036] The limiting arc blocks 18 are provided in pairs, and ten limiting arc blocks 18 are grouped in pairs. The surfaces of one group of limiting arc blocks 18 are fixedly connected with positioning rods 14. The surfaces of one group of limiting arc blocks 18 are provided with positioning holes 15. The size of the positioning rods 14 is adapted to the size of the positioning holes 15. The setting of the positioning holes 15 and the positioning rods 14 can achieve the alignment of the screw holes 6 between the main fixing frame 7 and the auxiliary fixing frame 8 during the installation process of the main fixing frame 7 and the auxiliary fixing frame 8, making it convenient for personnel to use the bolt rods 10 for fixing.

[0037] Four anti-slip sheets 13 are fixedly connected to the inner side of the support frame 9. The surface of the anti-slip sheets 13 is provided with anti-slip grooves. The anti-slip sheets 13 increase the friction between the sponge ring 11 and the support frame 9 to a certain extent, indirectly allowing the sponge ring 11 to be more stably placed on the inner walls of the main fixed frame 7 and the auxiliary fixed frame 8.

[0038] The implementation principle of the embodiment of the present application is as follows: the main fixing frame 7 and the auxiliary fixing frame 8 can be quickly combined through the positioning hole 15 and the positioning rod 14, so that the main fixing frame 7 and the auxiliary fixing frame 8 can clamp the ceramic bearing inside, and the threaded connection of the thread and the bolt rod 10 can make the main fixing frame 7 and the auxiliary fixing frame 8 be combined and fixed. At the same time, a sponge ring 11 is placed on the inner wall of the main fixing frame 7 and the auxiliary fixing frame 8. The sponge ring 11 absorbs the sweat of the hands of the personnel, thereby reducing the direct contact of sweat and other liquids with the surface of the ceramic bearing as much as possible. The convex thorns 17 on the limiting arc block 18 can make the sponge ring 11 limited to the inner wall of the main fixing frame 7 and the auxiliary fixing frame 8, avoiding the phenomenon that the sponge ring 11 shakes inside when the ceramic bearing rotates, and the anti-slip sheet 13 can further increase the stability of the connection between the sponge ring 11 and the main fixing frame 7 and the auxiliary fixing frame 8. .

[0039] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
