Description

Technical Field

[0001] This utility model relates to the field of filter-related technology, specifically a gasket structure for a raised filter. Background Technology

[0002] The primary function of filters in hydraulic systems is to remove solid contaminants from the working medium, maintaining its cleanliness. Most hydraulic system malfunctions are caused by contamination of the working medium, making filters indispensable. In hydraulic transmission systems, oil filtration devices are required to remove impurities such as iron filings and sludge from the oil.

[0003] The existing publication number CN221451880U discloses an in-tank oil return filter element, including a filter element housing and a retainer. A fine filter element is disposed within the filter element housing. A base is installed at one end of the filter element housing, and an upper end cover is installed at the end of the base away from the filter element housing. A filter element pressure ring is disposed between the upper end cover and the fine filter element. A coarse filter element and a retainer are installed at the end of the filter element housing away from the fine filter element. Through holes are opened on both sides of the filter element housing at the end of the retainer. A coarse filter element end cover and a bypass valve are installed at the end of the retainer away from the filter element housing. Oil enters through the interface on the side of the base, is filtered by the fine filter element, and then discharged through the through holes on both sides of the filter element housing. This improves the filtration accuracy and dirt holding capacity of the filter, and can filter oxides, harmful acids, and moisture generated during the use of lubricating oil, thereby greatly extending the service life of the lubricating oil. Filter paper is integrated into this filter element, increasing the filtration area and improving the filtration accuracy.

[0004] While existing technologies have increased the filtration area and improved filtration accuracy to some extent, they are prone to oil leakage due to poor sealing at the base. To solve the above technical problems, we propose a gasket structure for a raised filter. Utility Model Content

[0005] The purpose of this invention is to provide a gasket structure for a raised filter to solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gasket structure for a raised filter, comprising a gasket, the gasket comprising a gasket body, the gasket body having a through hole in the middle for a base to pass through, the gasket body having annular protrusions on both sides of the through hole, and the gasket body having a plurality of first through holes uniformly arranged on the outer side of the annular protrusions.

[0007] Preferably, the gasket body and the annular protrusion are an integral structure, and the gasket is made of rubber.

[0008] Preferably, it also includes a base, the base including a base body, the base body having an installation groove for mounting the gasket, the depth of the installation groove being less than the thickness of the gasket body.

[0009] Preferably, the base body has multiple second through holes corresponding to the first through hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: both sides of the gasket body are provided with annular protrusions, which can improve the sealing effect of the gasket, thus resulting in better sealing performance after the base is installed and preventing oil leakage.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] Please see Figure 1-4In this embodiment of the utility model, a gasket structure for a raised filter includes a gasket 2. The gasket 2 includes a gasket body 21. The gasket body 21 has a through hole in the middle for the base 1 to pass through. The gasket body 21 has annular protrusions 22 on both sides of the through hole. The gasket body 21 has a plurality of first through holes 23 evenly arranged on the outer side of the annular protrusions 22. The gasket body 21 and the annular protrusions 22 are an integral structure. The gasket 2 is made of rubber. The annular protrusions on both sides of the gasket body can improve the sealing effect of the gasket, so that the sealing performance after the base is installed is better and there will be no oil leakage problem.

[0019] It also includes a base 1, which includes a base body 11. The base body 11 has an installation groove 13 for mounting the gasket 2. The depth of the installation groove 13 is less than the thickness of the gasket body 21. The base body 11 has a plurality of second through holes 12 corresponding to the first through hole 23.

[0020] The working principle of this utility model is as follows: both sides of the gasket body are provided with annular protrusions. The use of annular protrusions can improve the sealing effect of the gasket, so that the sealing performance after the base is installed is better and there will be no oil leakage problem.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
