[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] In the present utility model, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0025] See also Figure 1-4 The oil filter assembly shown in the figure comprises a filter body 10, the outer side of the filter body 10 is provided with an external thread 11; it also comprises a sleeve, the sleeve is provided with a movable sleeve 13 which can slide in the axial direction, the inner side of the movable sleeve 13 is provided with an internal thread corresponding to the external thread 11; the side surface of the sleeve is provided with a pressing unit which can extend into the sleeve and press the movable sleeve 13, and the end of the sleeve is provided with a plurality of mounting feet 4.

[0026] Through the implementation of the above technical solution, during installation, firstly, the movable sleeve 13 is clamped by the pressing unit, and the filter body 10 is transferred into the movable sleeve 13 through the cooperation of the external thread 11 and the internal thread, and then the pressing unit is loosened, and the sleeve is installed into the preset screw hole on the vehicle body through the bolt passing through the mounting foot plate 4, and then the filter body 10 is rotated and the filter body 10 is screwed to the corresponding mounting position on the vehicle body, so that the oil filter assembly is installed in place. When the oil filter assembly is subjected to external lateral force, the force is sequentially transmitted to the movable sleeve 13, the sleeve, and then transmitted to the vehicle body through the mounting foot plate 4, thereby reinforcing the filter body 10, making the filter body 10 more stable, and being able to play a good reinforcing role on the filter body 10, and having strong resistance to external forces.

[0027] In this embodiment, the mounting foot plate 4 is provided with an oblong hole 5 extending in the radial direction of the filter body 10. With such a configuration, the mounting foot plate 4 has a wider installation application range.

[0028] In this embodiment, in order to further provide a sleeve structure, the sleeve includes an outer sleeve 1 and an inner sleeve 2 , and a plurality of connecting ribs 3 are fixedly connected between the outer sleeve 1 and the inner sleeve 2 .

[0029] In this embodiment, in order to further provide a pressing unit, the pressing unit includes an arc-shaped pressing plate 6; an optical axis 9 penetrating the outer cylinder 1 is provided on the back of the arc-shaped pressing plate 6; a pressing plate 7 is fixedly connected to the outer end of the optical axis 9, and a through hole capable of extending into the arc-shaped pressing plate 6 is provided on the side of the inner cylinder 2.

[0030] In one embodiment, two pressing units are symmetrically arranged, and two optical axes 9 are arranged on each pressing unit. By pressing the pressing plate 7, the arc pressure plate 6 is pushed to press on the outside of the movable sleeve 13 under the drive of the optical axis 9, so as to facilitate the spiral installation of the filter body 10 in the movable sleeve 13.

[0031] In this embodiment, a spring 8 is sleeved on the optical axis 9 between the pressing plate 7 and the outer cylinder 1. The spring 8 allows the arc-shaped pressing plate 6 to be released from the movable sleeve 13 under the reset action of the spring 8 after the pressing is released, and does not contact the movable sleeve 13, thereby avoiding excessive friction caused by contact friction when the movable sleeve 13 rotates, thereby preventing the filter body 10 from being installed on the vehicle body.

[0032] In this embodiment, a limit plate 12 is fixedly connected to the optical axis 9 between the outer cylinder 1 and the arc-shaped pressure plate 6. The limit plate 12 is provided to prevent the optical axis 9 from extending outward and causing shaking. When the spring 8 is in a normal state, the limit plate 12 is in a state of being pressed against the inner wall of the outer cylinder 1.
