For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Reference Figure 1-Figure 2 According to an embodiment of the utility model, an oil filter that is easy to disassemble and assemble includes a shell 11, a ring plate 12 is fixed to the outside of the shell 11, a first hinge groove 13 is provided in the curved surface of the ring plate 12, and a pull plate 14 is hinged in the first hinge groove 13, and a staff member can pull out the pull plate 14 to twist the shell 11 relative to the mounting platform in the vehicle. In addition, a force measuring mechanism is provided in the end surface of the ring plate 12 to measure the force exerted on the shell 11 when the pull plate 14 twists the shell 11, so as to avoid the oil filter that is easy to disassemble and assemble being over-tightened and causing damage to the sealing rubber ring therein.

[0027] In this embodiment, the force measuring mechanism includes an embedded block 15 embedded in the ring plate 12, a slide groove is provided in the embedded block 15, and a pressure plate 16 is connected to the slide groove through a spring, and the pressure plate 16 extends to the outside of the embedded block 15, and the pressure plate 16 can be pressed internally by the pull plate 14, and the embedded block 15 is also provided with an alarm device triggered according to the position of the pressure plate 16, the alarm device includes a buzzer provided in the embedded block 15, and a trigger device connected to the buzzer is provided on the bottom surface of the slide groove, and the trigger device can be triggered by the pressure plate 16, that is, when the staff uses the pull plate 14 to tighten the shell 11, the pull plate 14 will abut against the pressure plate 16, when the shell 11 is installed firmly enough, the pressure plate 16 will be pressed internally and the buzzer will be controlled to work through the trigger device, so as to prompt the staff to reduce the force and avoid over-tightening.

[0028] In this embodiment, in order to facilitate the packaging of the outer shell 11, a No. 2 hinge groove 17 is provided in the outer curved surface of the ring plate 12, and the embedded block 15 is hinged in the No. 2 hinge groove 17. In addition, a limit plate 31 for limiting the angle of the embedded block 15 is also provided in the ring plate 12. When it is necessary to install the oil filter that is easy to disassemble and assemble, the staff first pulls out the embedded block 15 until it abuts against the limit plate 31, and then pulls out the pull plate 14 until the pull plate 14 abuts against the pressure plate 16. At this time, the pressure plate 16 can abut against the side of the No. 2 hinge groove 17 to be diagonally supported on the pull plate 14.

[0029] In the second embodiment of the oil filter that is easy to disassemble and assemble, an empty groove is provided in the pull plate 14, and a support rod 18 is hinged in the empty groove, and a clamping groove for clamping the support rod 18 is provided in the inner curved surface of the No. 1 hinge groove 13. When the staff needs to disassemble the outer shell 11, the outer shell 11 needs to be reversed. At this time, the staff pulls out the pull plate 14 and then pulls out the support rod 18. At this time, the support rod 18 can be inserted into the clamping groove and support the pull plate 14. At this time, the staff can use the pull plate 14 supported by the support rod 18 to reverse the ring plate 12 and the outer shell 11, so that the oil filter that is easy to disassemble and assemble can be disassembled.

[0030] After the previous filter is disassembled, the sealing rubber ring inside it is easy to stick to the installation platform in the car. At this time, if the staff directly installs the oil filter that is easy to disassemble, the two sealing rubber rings will fit each other, and oil leakage is very likely to occur. Therefore, in the third embodiment of the oil filter that is easy to disassemble, a fool-proof design is also made: a permanent magnet 19 is provided in the inner curved surface of the No. 1 hinge groove 13 for attracting the pull plate 14 and making the pull plate 14 stick to the curved surface of the No. 1 hinge groove 13; in addition, a convex plate 20 extending axially along the outer shell 11 is provided on the side of the ring plate 12; a push rod 21 is connected to the convex plate 20 for sliding up and down, and the end of the push rod 21 is stuck to the inclined surface 22 in the pull plate 14.

[0031] Specific installation process:

[0032] First, the staff manually screws the housing 11 into the in-vehicle mounting platform. During this process, the end face of the housing 11 gradually approaches the in-vehicle mounting platform, and during this process, the push rod 21 is pressed by the in-vehicle mounting platform and squeezes the pull plate 14 out through the inclined surface, so that the pull plate 14 can be pulled out by the staff.

[0033] If there is an unremoved sealing rubber ring on the mounting platform in the vehicle, the push rod 21 will not be pressed inward, that is, at this time the pull plate 14 is still embedded in the No. 1 hinge groove 13 and is difficult to be removed. This fool-proof design ensures the reliability of the installation of the easily disassembled oil filter and avoids the problem of installing the easily disassembled oil filter before the previous sealing rubber ring is removed.

[0034] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
