Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An easy-to-maintain oil removal filter includes an oil removal filter body 1, which includes an upper housing 101 and a lower housing 102. A docking positioning component 2 is provided between the upper housing 101 and the lower housing 102, and connecting and fixing components 3 are provided around the docking positioning component 2.

[0029] The docking positioning assembly 2 includes a positioning disk 201 and a docking ring block 202. The positioning disk 201 is fixedly connected to the top of the surface of the lower housing 102, and the docking ring block 202 is fixedly connected to the bottom of the surface of the upper housing 101. The top of the positioning disk 201 is provided with a positioning groove 203 that cooperates with the docking ring block 202. The docking ring block 202 is located in the positioning groove 203. Positioning sliders 204 are fixedly connected to all four sides of the docking ring block 202. Positioning grooves 205 that cooperate with the positioning sliders 204 are provided on all four sides of the inner wall of the positioning groove 203. The positioning sliders 204 are slidably connected in the positioning grooves 205.

[0030] In this embodiment, by setting up an oil removal filter body 1, an upper housing 101, a lower housing 102, a docking positioning component 2, and a connecting and fixing component 3, during use, the docking positioning component 2 enables the upper housing 101 and the lower housing 102 to be accurately and quickly docked and positioned after the internal structure maintenance of the oil removal filter body 1 is completed, effectively reducing the installation difficulty and improving the installation efficiency. The connecting and fixing component 3 allows the upper housing 101 and the lower housing 102 to be connected and fixed after the docking positioning component 2 has docked and positioned them. This connection and fixing method is convenient, making the disassembly and installation of the upper housing 101 and the lower housing 102 easier during the maintenance of the internal structure of the oil removal filter body 1, thus providing convenience for the user.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the connecting and fixing assembly 3 includes a fixing plate 301, which is fixedly connected to the bottom of the positioning plate 201. The bottom of the fixing plate 301 on the side away from the lower housing 102 is rotatably connected to a telescopic air rod 302 via a damping shaft.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the output rod of the telescopic air rod 302 is fixedly connected to a connecting plate 303. A pressing block 304 is fixedly connected to the bottom of the connecting plate 303 near the upper housing 101. A rubber pad 305 is fixedly connected to the bottom of the pressing block 304.

[0033] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, the top of the docking ring block 202 is provided with a slot 4 that works with the pressing and fixing block 304. The side of the pressing and fixing block 304 near the inner wall of the slot 4 contacts the inner wall of the slot 4, and the bottom of the rubber pad 305 is in close contact with the bottom of the inner wall of the slot 4.

[0034] In this embodiment: by setting a fixed plate 301, a telescopic air rod 302, a connecting plate 303, a pressing fixing block 304, a rubber pad 305, and a slot 4, after the docking ring block 202 is docked with the positioning plate 201, the telescopic air rod 302 can be rotated to a vertical state via the damping shaft. Then, the telescopic air rod 302 is activated, causing the output rod of the telescopic air rod 302 to retract and drive the connecting plate 303 to move downward. This causes the connecting plate 303 to drive the pressing fixing block 304 into the slot 4 of the docking ring block 202, and then press down. As the fixing block 304 continues to move downward, the pressing fixing block 304 presses down against the inner wall of the slot 4 through the rubber pad 305, thereby firmly fixing the docking ring block 202 in the positioning groove 203 of the positioning plate 201. This connects and fixes the upper housing 101 and the lower housing 102. The fixing method is relatively convenient to operate, and disassembly can be performed by reversing the operation. Therefore, when maintaining the internal structure of the oil filter body 1, the disassembly and installation of the upper housing 101 and the lower housing 102 are relatively convenient, bringing convenience to the user.

[0035] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, an annular sealing gasket 5 is fixedly connected to the bottom of the docking ring block 202, and the bottom of the annular sealing gasket 5 is in close contact with the bottom of the inner wall of the positioning groove 203.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, a sealing ring 6 is fitted on the bottom of the surface of the docking ring block 202. The side of the sealing ring 6 near the inner wall of the positioning groove 203 is in close contact with the inner wall of the positioning groove 203. A positioning ring groove 7 is opened on the bottom of the surface of the docking ring block 202 to cooperate with the sealing ring 6. The sealing ring 6 is snapped into the positioning ring groove 7.

[0037] In this embodiment: by setting the annular sealing gasket 5, the bottom of the docking ring block 202 and the bottom of the inner wall of the positioning groove 203 can be sealed to prevent the filtered fluid from leaking. By setting the sealing ring 6, the surface of the docking ring block 202 and the inner wall of the positioning groove 203 can be sealed, thereby achieving a double sealing effect. By setting the positioning ring groove 7, the position of the sealing ring 6 can be positioned.

[0038] Specifically, such as Figure 1 As shown, a support leg 8 is fixedly connected to the bottom of the surface of the lower housing 102. There are three support legs 8, which are evenly distributed on the bottom of the surface of the lower housing 102.

[0039] Specifically, such as Figure 1 As shown, a mounting plate 9 is fixedly connected to the bottom of the support leg 8, and a mounting hole 10 is provided on the top of the mounting plate 9.

[0040] In this embodiment: by setting support legs 8, the oil removal filter body 1 can be supported. By setting mounting plate 9 and mounting holes 10, the support legs 8 can be easily fixed to the ground or other support components using bolts.

[0041] Working principle: During installation, the upper housing 101 and the lower housing 102 are aligned. The alignment ring 202 on the upper housing 101 is inserted into the positioning groove 203 of the positioning plate 201 of the lower housing 102, and the positioning slider 204 is inserted into the positioning groove 205. This achieves quick alignment and positioning of the upper housing 101 and the lower housing 102, effectively reducing installation difficulty and improving installation efficiency. After alignment, the telescopic air rod 302 can be rotated to a vertical position via the damping shaft. Then, the telescopic air rod 302 is activated, causing its output rod to retract and drive the connecting plate 303 downwards. The connecting plate 303 moves, causing the pressing and fixing block 304 to enter the slot 4 of the docking ring block 202. Then, the pressing and fixing block 304 continues to move downward, pressing and abutting the inner wall of the slot 4 through the rubber pad 305. This firmly fixes the docking ring block 202 in the positioning groove 203 of the positioning plate 201, thus connecting and fixing the upper housing 101 and the lower housing 102. The fixing method is relatively convenient to operate, and disassembly can be performed by reversing the operation. Therefore, when maintaining the internal structure of the oil filter body 1, the disassembly and installation of the upper housing 101 and the lower housing 102 are relatively convenient, bringing convenience to the user.

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