Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a novel hole-shaft universal combined sealing ring. Background Art

[0002] A sealing ring, also known as a gasket, sealing ring or O-ring, is a device used to seal between two or more interconnected parts. It is usually made of annular rubber, plastic, metal or other materials with a circular or annular cross-section.

[0003] However, some existing combined sealing rings are directly installed in the limiting grooves where the sealing rings are set when they are used. When lubricating, the lubricating oil will pass through the gap between the sealing ring and the shaft component, or through the gap between the sealing ring and the limiting groove for lubrication. No lubricating oil will be left on the sealing ring. At connections with high frequency of use, lubricating oil needs to be used frequently, which is more troublesome. If lubricating oil is not used, the sealing ring at that location will have greater operating resistance when the equipment is working, thereby reducing its service life. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing sealing ring has no function of temporarily storing lubricating oil, so that the sealing ring needs to be frequently lubricated, which is troublesome to operate.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is a new type of universal hole-shaft combined sealing ring, including an outer gasket structure, a mosaic gasket structure is provided on the inner side of the outer gasket structure, the mosaic gasket structure includes an upper ring and a lower ring, a plurality of mosaic grooves are opened on the lower side of the upper ring, and mosaic blocks are fixed on the upper side of the lower ring at the mosaic grooves, and a plurality of arc-shaped grooves are opened on the side adjacent to the mosaic groove and the mosaic block.

[0006] As a further solution of the utility model: the outer gasket structure includes an upper gasket and a lower gasket, and an oblique matching structure is provided on the side where the upper gasket contacts the lower gasket, so as to prevent left-right deviation between the upper gasket and the lower gasket.

[0007] As a further solution of the utility model: annular grooves are provided on the lower side of the upper washer and the upper side of the lower washer, and the upper ring and the lower ring are respectively located in the two annular grooves, which can limit the positions of the upper ring and the lower ring.

[0008] As a further solution of the utility model: the upper washer, the lower washer, the upper circle and the lower circle exist independently of each other, and gaps are left when they are matched to facilitate the penetration of lubricating liquid.

[0009] As a further solution of the utility model: small through holes are opened on the side surfaces of the upper circle and the lower circle at the arc-shaped groove holes to facilitate the lubricating liquid to penetrate into the arc-shaped groove holes.

[0010] Compared with the prior art, the utility model has the following advantages: the utility model adds an arc-shaped groove structure between the upper circle and the lower circle, which can retain a certain amount of lubricating oil, eliminating the need for frequent oiling, and adds small through holes to facilitate the flow of lubricating oil.

[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 a technical solution to solve the existing problems raised in the background technology.

[0022] Combined with Figure 3 , 4 6, it can be known that the sealing ring includes an outer gasket structure, the inner side of the outer gasket structure is provided with a fitting gasket structure, the fitting gasket structure includes an upper ring 1 and a lower ring 2, a plurality of fitting grooves 1.1 are provided on the lower side of the upper ring 1, and fitting blocks 2.1 are fixed at the fitting grooves 1.1 on the upper side of the lower ring 2, and a plurality of arc-shaped slots 3 are provided on the side adjacent to the fitting grooves 1.1 and the fitting blocks 2.1 for temporarily storing lubricating oil; the upper gasket 4, the lower gasket 5, the upper ring 1, and the lower ring 2 exist independently of each other, and gaps are left when they are matched to facilitate the infiltration of lubricating liquid;

[0023] Combined with Figure 1 , 2 , 5, it can be seen that the outer gasket structure includes an upper gasket 4 and a lower gasket 5, and a diagonal matching structure is provided on the side where the upper gasket 4 contacts the lower gasket 5, which is used to prevent the upper gasket 4 and the lower gasket 5 from being offset to the left and right; an annular groove is provided on the lower side of the upper gasket 4 and the upper side of the lower gasket 5, and the upper ring 1 and the lower ring 2 are respectively located in the two annular grooves, which can limit the position of the upper ring 1 and the lower ring 2; a small through hole 6 is provided on the side of the upper ring 1 and the lower ring 2 at the arc-shaped groove hole 3, so as to facilitate the lubricating liquid to penetrate into the arc-shaped groove hole 3;

[0024] The working principle of the present application is as follows: during lubrication, the lubricating oil will enter the annular groove through the gap between the upper gasket 4 and the lower gasket 5, and then the lubricating oil will enter between the upper circle 1 and the lower circle 2 and inside the arc-shaped groove 3 through the small through hole 6 and the gap. Some of the lubricating oil will temporarily remain therein, so that there is no need to frequently add lubricating oil there.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
