Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the utility model easily understood, the utility model is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the utility model, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention are described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-2, a convenient and fast replaceable oil filter assembly comprises a rubber ring 3, a lower shell 4 is fixed at the upper end of the rubber ring 3, a check valve 2 is sleeved at the upper end of the lower shell 4, a filter element 5 is fixed at the upper end of the check valve 2, an upper shell 1 is sleeved at the upper end of the filter element 5, the lower shell 4 comprises a ring body 42, an insertion groove 41 is fixed at the upper end of the ring body 42, the upper shell 1 comprises a protective shell 12, and a fixing plate 11 is fixed at the upper end of the protective shell 12.

Connecting the filter assembly with an external engine oil pipeline, controlling the external pipeline to charge engine oil into the upper shell 1, enabling the engine oil to enter the upper shell 1, and be extruded by subsequent engine oil to pass through a filtering hole on the surface of the filter element 5, removing impurities in the engine oil, enabling the engine oil passing through the filter element 5 to pass through the check valve 2 along the hollow filter element 5 and finally enter the engine, enabling the upper shell 1 to move upwards relative to the lower shell 4 through an external tool after the filter element 5 is used for a long time, enabling the upper shell 1 to move to drive the fixing plate 11 on the surface to move, enabling the fixing plate 11 to be separated from the slot 41, enabling the upper shell 1 to be separated from the lower shell 4, taking out the filter element 5 to clean and replace the filter element 5, enabling the fixing plate 11 on the surface of the protective shell 12 to be mutually connected with the slot 41 on the surface of the ring body 42, and completing the fixing between the upper shell 1 and the lower shell 4, when needing to be dismantled, the upper shell 1 and the lower shell 4 can be separated by using an external hydraulic device, waste caused by replacing the whole filter assembly at one time is avoided, and unnecessary waste is reduced.
