Description

Static waterproof dustproof sealing ring Technical Field The utility model belongs to the technical field of sealing rings, and relates to a static waterproof dustproof sealing ring. Background In the current hub unit manufacturing process, the connection of the mandrel portions is typically accomplished using a spin riveting process. However, such spin riveting processes tend to cause deformation of the inner ring dimensions during operation, which is a disadvantage for maintaining the accuracy and performance of the hub. In addition, the operation difficulty in the spin riveting process is high, and ideal tightness between the hub mandrel and the hub inner ring is difficult to ensure, so that invasion of pollutants such as water, dust and the like can be caused, and the service life and reliability of the hub are affected. In view of these problems, it becomes very critical to design a static waterproof and dustproof sealing ring. Disclosure of Invention In order to solve the defects in the prior art, the utility model provides a static waterproof dustproof sealing ring. The static waterproof and dustproof sealing ring is characterized in that the cross section of the framework is Z-shaped, an inner ring sealing lip and a mandrel sealing lip are arranged on the rubber body, the lip of the inner ring sealing lip is contacted with the inner ring of the hub unit, and the lip of the mandrel sealing lip is contacted with the hub mandrel. The inner ring sealing lip is arranged obliquely outwards, and the mandrel sealing lip is arranged obliquely inwards. The inner ring sealing lip is positioned at the end part of one end of the framework, and the mandrel sealing lip is positioned at the end part of the other end of the framework. And a reinforcing colloid is arranged between the root of the mandrel sealing lip and the end part of the other end of the framework. The inner side surface of one end of the framework and the inner side surface of the middle section of the framework are contacted with the inner ring of the hub unit. By adopting the technical scheme, the utility model has the beneficial effects that: The waterproof and dustproof sealing ring can replace a spin riveting process, and can effectively prevent invasion of dust and muddy water on the outer side. Drawings Fig. 1 is a schematic structural view of the present utility model. In the figure, 1a, a framework, 1b, a rubber body, 1c, an inner ring sealing lip, 1d, a mandrel sealing lip, 1e, a hub unit outer ring, 1f, a hub oil seal, 1g, a hub unit inner ring, 1h, a hub mandrel and 1i, a reinforcing colloid. Detailed Description In order to further explain the technical scheme of the utility model, the utility model is explained in detail by specific examples. As shown in FIG. 1, the static waterproof dustproof sealing ring comprises a framework 1a, wherein a rubber body 1b is arranged on the framework 1a, the cross section of the framework 1a is Z-shaped, an inner ring sealing lip 1c and a mandrel sealing lip 1d are arranged on the rubber body 1b, the lip of the inner ring sealing lip 1c is in contact with an inner ring 1g of a hub unit, the inner ring sealing lip 1c is static sealing, muddy water is prevented from entering the hub mandrel 1h through the inner ring 1g of the hub unit, the lip of the mandrel sealing lip 1d is in contact with the hub mandrel 1h, the mandrel sealing lip 1d is static sealing, muddy water is prevented from entering the hub mandrel 1h, the inner ring sealing lip 1c is obliquely outwards arranged, and the mandrel sealing lip 1d is obliquely inwards arranged. The inner ring sealing lip 1c is positioned at the end part of one end of the framework 1a, the mandrel sealing lip 1d is positioned at the end part of the other end of the framework 1a, and a reinforcing colloid 1i is arranged between the root part of the mandrel sealing lip 1d and the end part of the other end of the framework 1 a. The inner side surface of one end of the framework 1a and the inner side surface of the middle section of the framework 1a are contacted with the inner ring 1g of the hub unit. In summary, by adopting a static sealing structure, external dust and muddy water can be effectively prevented from invading the inside of the mandrel, thereby avoiding failure of the hub unit caused by rust. All the components are general standard components or components known to the person skilled in the art, and the structures and principles of the components are known to the person skilled in the art through technical manuals or through routine experimental methods. The above examples and drawings are not intended to limit the form or form of the present utility model, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present utility model.
