Abstract

The invention discloses a retaining plate sealing structure for an oil filter. The retaining plate sealing structure comprises a housing and a bracket; the lower part of the housing is connected with a cylindrical cover with a filter element; an oil inlet through hole is formed in the position, on the end part of the upper part of the housing, of the lower part of an oil inlet; a retaining plate is arranged on a position, above the filter element, on the lower part of the oil inlet through hole; the middle part of the retaining plate is equipped with a ring-shaped lug boss with a threaded through hole; a concave part is arranged on the side surface, which is in contact with the end opening of the housing, of the ring-shaped lug boss; the concave part can be used for receiving a sealing component used for blocking oil flow between the end opening of the housing and the ring-shaped lug boss in a matched manner; and an elastic sealing pad is arranged on the end surface, which is in contact with the inner wall of the end part of the housing, of the retaining plate. According to the retaining plate sealing structure disclosed by the invention, a structure for sealing through the sealing component and the elastic sealing pad is adopted on the retaining plate, so that the occurrence probability of the oil leakage problem of the oil filter is effectively reduced, and the sealing property of the retaining plate is greatly improved; and the retaining plate is not easily loosened even under a long-term vibrating condition, so that working stability performance of the oil filter is strengthened.

Description

technical field [0001] The invention relates to the technical field of oil filter sealing for automobiles, in particular to a sealing structure of a retaining plate for an oil filter. Background technique [0002] Generally, a filter for an automobile includes a housing and a bracket, and the housing and the bracket are detachably connected. An oil inlet and an oil outlet are often set on the bracket, and the lower end of the housing is connected with a cylinder threaded with a filter element. It is used to communicate with the oil inlet on the bracket. A retaining plate is provided between the end and the cylinder, and a through hole is also provided on the retaining plate to communicate with the oil inlet and the filter cavity in the cylinder. The holding plate not only plays the role of connecting the shell and the cylindrical filter cavity, but also plays the role of sealing the oil inlet and outlet. Therefore, the performance and sealing degree of the holding plate dir...
