AI Technical Summary
The sealing properties of existing rubber seals are sharply attenuated in high temperature and high pressure environments, resulting in oil leakage failure of the engine oil filter base assembly.
A rubber seal is designed, including the sealing body consisting of an annular sealing ring, and the annular sealing ring is provided with a tight ring structure and a sealing protrusion. The tight ring structure includes a continuous protrusion in the middle of the inner and outer contours of the annular sealing ring. The sealing protrusion is continuously and uninterrupted on the upper and lower end surfaces, improving sealing properties and pressure-changing rebound performance.
By adding the tight ring rib structure and sealing protrusion, the rubber seal maintains good sealing performance in high temperature and high pressure environments, preventing oil leakage and failure of the engine oil filter base assembly, extending service life, and being simple in structure, easy to process and easy to assemble.

Abstract
Description
Technical Field
[0001] The utility model relates to a sealing device, in particular to a rubber sealing piece. Background Art
[0002] The existing rubber seals have multiple tight-fitting points evenly distributed on the inner and outer contours of the rubber seals, which are then tightly fitted with the sealing groove of the oil filter base assembly to prevent swinging and falling off. The cross-section of some sealing points and the volume ratio of the sealing groove exceed 100%, which will cause the rubber seals to experience a sharp decline in compression resilience sealing performance under high temperature and high pressure conditions after installation, causing the oil filter base assembly to leak and fail. Utility Model Content
[0003] In view of the deficiencies in the existing technology, the utility model provides a rubber sealing element.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a rubber seal, including a seal body, the seal body is composed of at least one annular sealing ring, the annular sealing ring is provided with a tight-fitting ring rib structure, the tight-fitting ring rib structure includes a first protrusion arranged in the middle of the inner contour of the annular sealing ring and a second protrusion arranged in the middle of the outer contour of the annular sealing ring, the first protrusion continuously and uninterruptedly surrounds the inner contour of the annular sealing ring, and the second protrusion continuously and uninterruptedly surrounds the outer contour of the annular sealing ring.
[0005] The upper and lower end surfaces of the annular sealing ring are respectively provided with sealing protrusions, and the sealing protrusions include a third protrusion close to the inner contour of the annular sealing ring and a fourth protrusion close to the outer contour of the annular sealing ring.
[0006] The third protrusion continuously and uninterruptedly surrounds the upper end surface of the annular sealing ring, and the fourth protrusion continuously and uninterruptedly surrounds the lower end surface of the annular sealing ring.
[0007] The sealing body is an integrated structure made of rubber.
[0008] The beneficial effects of the utility model are as follows: a tight-fitting ring rib structure is added in the middle position of the rubber seal of the utility model, which is tightly fitted with the sealing groove of the oil filter base assembly. The cross-section of the rubber seal at any position is uniformly consistent with the volume ratio of the sealing groove, which meets the volume ratio standard; and sealing protrusions are added to the upper and lower end surfaces of the rubber seal to improve the sealing performance; after the rubber seal is installed on the vehicle, in a high temperature and high pressure environment, the pressure-dependent rebound sealing performance is effectively increased, the oil filter base assembly is prevented from leaking and failing, and the service life is increased.
[0009] The utility model also has the characteristics of simple structure, convenient processing and easy assembly, and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
