Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to an oil filter. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. An oil filter is one type of filter, located in the engine lubrication system. Existing oil filters consist of a body and a mounting bracket, with the body typically screwed directly onto the mounting bracket.

[0003] However, the single threaded connection between the main body and the mounting base results in poor installation stability of the main body. Utility Model Content

[0004] The purpose of this application is to provide an oil filter that solves the problem of poor stability caused by the use of a single threaded connection in the main body of the oil filter in the related art.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] This application provides an oil filter, including a body and a mounting base. The body has a protrusion that abuts against the mounting base. Corresponding slots are formed on the protrusion and the mounting base. The slots are constructed in an arc shape along their cross-section, and a limit post is engaged inside the slots.

[0007] The oil filter provided in this application embodiment engages with both the mounting base and the slot on the protrusion via a limiting post. Compared to the prior art, this allows for circumferential limiting of the main body, improving the stability of the main body when installed on the mounting base.

[0008] In some embodiments, the bump is configured as an arc.

[0009] In some embodiments, the bump and the mounting base are arranged coaxially.

[0010] In some embodiments, the protrusion abuts against the top surface of the mounting base.

[0011] In some embodiments, the outer wall of the protrusion and the outer wall of the mounting base are located on the same circumferential surface.

[0012] In some embodiments, the axis of the card slot is arranged parallel to the axis of the mounting base.

[0013] In some embodiments, a shaft hole is provided at the axis of the limiting post.

[0014] In some embodiments, the sidewall of the limiting post is provided with an opening communicating with the shaft hole.

[0015] In some embodiments, the opening is arranged radially along the limiting post.

[0016] In some embodiments, the openings are spaced apart along the axial direction of the limiting post. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0025] A filter is an accessory that uses filter paper to filter impurities or gases. An oil filter is one type of filter, located in the engine lubrication system. Existing oil filters consist of a body and a mounting bracket, with the body typically screwed directly onto the mounting bracket.

[0026] However, the single threaded connection between the main body and the mounting base results in poor installation stability of the main body.

[0027] Based on the above considerations, in order to solve the problem of poor stability caused by the use of a single threaded connection in the main body of the oil filter in the relevant technology, an oil filter is designed that uses a limiting post to simultaneously engage with the mounting base and the slot on the protrusion. Compared with the existing technology, this can circumferentially limit the main body and improve the stability of the main body when installed on the mounting base.

[0028] The oil filter of the present application embodiment will now be described in detail.

[0029] Please see Figures 1 to 2This application provides an oil filter 100, including a main body 10 and a mounting base 20. The main body 10 is provided with a protrusion 11 that abuts against the mounting base 20. Corresponding slots 21 are formed on the protrusion 11 and the mounting base 20. The slots 21 are constructed in an arc shape along the cross section. A limit post 12 is engaged inside the slots 21.

[0030] The main body 10 and the mounting base 20 are arranged coaxially. The main body 10 is screwed into the inside of the mounting base 20. When the main body 10 is installed in place on the mounting base 20, the protrusion 11 abuts against the end face of the mounting base 20. At this time, the slot 21 on the protrusion 11 and the slot 21 on the mounting base 20 are aligned. The limiting post 12 simultaneously forms a snap-fit ​​engagement with the protrusion 11 and the slot on the mounting base 20.

[0031] The slot 21 is constructed in an arc shape along its cross section. The cylindrical limiting post 12 is fitted into the slot 21 in a matching shape, which can restrict the limiting post 12 inside the slot 21 and prevent the limiting post 12 from detaching from the slot 21, thus ensuring the stability of the connection between the limiting post 12 and the slot 21.

[0032] It should be understood that the limiting post 12 engages with both the protrusion 11 and the slot 21 on the mounting base 20, which prevents relative rotation between the main body 10 and the mounting base 20 and improves the stability of the main body 10 on the mounting base 20.

[0033] The limiting post 12 has a certain degree of elasticity and can be squeezed into the slot 21.

[0034] The oil filter 100 provided in this application embodiment can be engaged with the mounting base 20 and the slot 21 on the protrusion 11 by the limiting post 12. Compared with the prior art, it can circumferentially limit the main body 10 and improve the stability of the main body 10 on the mounting base 20.

[0035] Please see Figures 1 to 2 The bump 11 is constructed in an arc shape.

[0036] The protrusion 11 is welded to the outer wall of the main body 10, and the protrusion 11 and the mounting base 20 are arranged coaxially. After the main body 10 is installed on the mounting base 20, the protrusion 11 is in contact with the top surface of the mounting base 20, and the outer wall of the protrusion 11 and the outer wall of the mounting base 20 are located on the same circumferential surface.

[0037] The axis of the slot 21 is arranged parallel to the axis of the mounting base 20. The limiting post 12 is engaged inside the slot 21. The limiting post 12 and the slot 21 are arranged coaxially. The upper end of the limiting post 12 abuts against the bottom of the slot 21 on the protrusion 11, and the lower end of the limiting post 12 abuts against the bottom of the slot 21 on the mounting base 20.

[0038] By simultaneously engaging the limiting post 12 with the mounting base 20 and the slot 21 on the protrusion 11, the main body 10 can be circumferentially limited compared to the prior art, thus improving the stability of the main body 10 when installed on the mounting base 20.

[0039] Please see Figures 1 to 2 In some embodiments, a shaft hole 121 is provided at the axis of the limiting post 12.

[0040] An opening 122 communicating with the shaft hole 121 is provided on the side wall of the limiting post 12, and the opening 122 is arranged radially along the limiting post 12 and spaced apart along the axial direction of the limiting post 12.

[0041] By using a hook or other tool to insert into the opening 122 and hook onto the shaft hole 122, the limiting post 12 can be pulled out from the slot 21, making it easier to disassemble the limiting post 12.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
