Specific embodiments

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] Embodiment 1: A filtering device for lubricating oil, such as Figure 1 , Figure 2 , Figure 5 , and Figure 7As shown in the figure, it includes a bracket 1, a filter 2, a sealing cover 3, a connecting shaft 32, a filter net 21, a mounting assembly and a locking assembly. The filter 2 is mounted on the bracket 1. On the right side of the top of the filter 2, the connecting shaft 32 is rotatably mounted. The sealing cover 3 is mounted on the connecting shaft 32 to seal the filter 2 and prevent unfiltered oil from flowing directly in or external impurities from entering. Inside the filter 2, the filter net 21 is movably mounted to intercept larger particles of impurities. A finer filter bag is also sleeved inside the filter net 21 to further purify the lubricating oil. At the top of the filter net 21, a mounting assembly is movably arranged, which makes the assembly and disassembly of the filter bag simple and fast, significantly improving the efficiency of replacing the filter bag. The mounting assembly is provided with a locking assembly to fix the filter net 21 inside the filter 2 and prevent it from shifting due to oil pressure or vibration during the filtering process, and also greatly simplifies the installation process, enabling users to easily complete the installation and disassembly of the filter net.

[0024] As Figure 3 and Figure 4 , Figure 5 and Figure 6 As shown in the figure, the mounting assembly includes a pressing plate 4, a second buckle 41, a first spring 42 and a fixing block 43. The pressing plate 4 is movably mounted on the top of the filter net 21 to apply appropriate pressure to ensure that the filter bag fits flatly on the filter net 21, so as to achieve effective filtration. On the bottom of the pressing plate 4, fixing blocks 43 are symmetrically arranged. The second buckle 41 is slidably mounted on the fixing block 43. A first spring 42 is arranged between the second buckle 41 and the fixing block 43. Notches are symmetrically opened at the top of the filter net 21. The second buckle 41 is clamped with the notches at the top of the filter net 21. The second buckle 41 can be firmly clamped with the notches at the top of the filter net 21 under the rebounding action of the first spring 42, thereby reliably fixing the pressing plate 4 on the filter net 21. When the filter bag needs to be replaced, the operator only needs to lift the pressing plate 4 upward. At this time, the first spring 42 is compressed, so that the second buckle 41 is disengaged from the notches at the top of the filter net 21, thus releasing the fixing state of the pressing plate 4 on the filter net 21.

[0025] As Figure 7As shown, the locking assembly includes a first sliding shaft 51, a second spring 52, a connecting plate 6, a connecting rod 61 and a wedge block 64. The first sliding shafts 51 are symmetrically installed on the pressing plate 4. The connecting plate 6 is slidably installed on the first sliding shafts 51. The first sliding shafts 51 play a guiding role to ensure that the connecting plate 6 can slide smoothly along the first sliding shafts 51. A second spring 52 is arranged between the bottom of the connecting plate 6 and the first sliding shafts 51. The connecting rods 61 are symmetrically and slidably arranged on the connecting plate 6. Wedge blocks 64 are symmetrically arranged on the inner wall of the filter 2 at positions corresponding to the connecting plate 6. A notch is formed at one end of the connecting rod 61 close to the inner wall of the filter 2. The wedge block 64 is clamped with the notch of the connecting rod 61. The second spring 52 provides a restoring force. When the connecting plate 6 is released, the connecting plate 6 is ejected outwards under the rebounding action of the second spring 52, driving the connecting rods 61 on the connecting plate 6 to be disengaged from the wedge block 64. At this time, the notch of the connecting rod 61 is automatically clamped with the wedge block 64, thereby locking the filter screen 21 in the filter 2.

[0026] As Figure 7 shown, it further includes a third spring 62 and a second sliding shaft 63. The second sliding shaft 63 is slidably installed in the connecting rod 61. The second sliding shaft 63 provides additional guidance for the connecting rod 61 to ensure the smooth sliding of the connecting rod 61 when performing locking or unlocking. A third spring 62 is arranged between the second sliding shaft 63 and the inner wall of the connecting plate 6. When the connecting rod 61 is pushed by an external force to be separated from the wedge block 64, the third spring 62 is compressed; when the external force is removed, the restoring force of the third spring 62 will push the second sliding shaft 63 and the connecting rod 61 back to their original positions, so that the notch of the connecting rod 61 is re-clamped with the wedge block 64 to achieve the automatic locking function.

[0027] Before use, rotate the sealing cover 3 upward through the connecting shaft 32 to make the sealing cover 3 in an open state. Then, put the filter bag set on the filter net 21, place the pressing plate 4 on the top of the filter net 21, ensure that the fixing block 43 at the bottom of the pressing plate 4 is aligned with the notch at the top of the filter net 21, press the pressing plate 4, so that the second buckle 41 on the fixing block 43 contacts the notch at the top of the filter net 21. At this time, the first spring 42 is compressed. Release the pressing plate 4, and the second buckle 41 is clamped with the notch at the top of the filter net 21 under the rebounding action of the first spring 42, completing the preliminary fixation of the filter net 21 and the filter bag. Next, pull the connecting rods 61 on both sides towards the center of the connecting plate 6, compress the third spring 62, so that the connecting rods 61 slide towards the center of the connecting plate 6 along the second sliding shaft 63. At this time, the length of the connecting rods 61 is shortened, which is convenient for the filter net 21 to be placed inside the filter 2. After accurately placing the filter net 21 inside the filter 2, align the two ends of the connecting plate 6 with the wedge-shaped blocks 64 on the inner wall of the filter 2. First, press the connecting plate 6 downward, compress the second spring 52, so that the connecting plate 6 slides downward along the first sliding shaft 51 until the connecting plate 6 and the connecting rods 61 thereon move downward to a position aligned with the wedge-shaped blocks 64. At this time, release the connecting rods 61, and the resilience of the third spring 62 drives the connecting rods 61 to pop outwards, and the wedge-shaped blocks 64 are accurately clamped with the notches of the connecting rods 61, completing the final locking of the filter net 21. Subsequently, rotate the sealing cover 3 along the connecting shaft 32 to align it with the corresponding position of the first buckle 31, press down the sealing cover 3, and the first buckle 31 is clamped with the sealing cover 3, completing the installation of the sealing cover 3 to ensure the sealing inside the filter 2. Inject lubricating oil into the filter 2 through the oil inlet. The lubricating oil flows through the filter bag, and the impurities therein are intercepted by the filter bag. The clean lubricating oil continues to pass through the filter net 21, and the filtered lubricating oil flows out from the oil outlet, completing the filtering process. When the filtering is completed, pull the connecting rods 61 on both sides towards the center of the connecting plate 6, compress the third spring 62, so that the connecting rods 61 slide towards the center of the connecting plate 6 along the second sliding shaft 63, and the wedge-shaped blocks 64 are disengaged from the notches of the connecting rods 61, thus releasing the locking of the filter 2 on the filter net 21. Subsequently, lift the connecting plate 6 upward to easily take out the filter net 21 for the next use.

[0028] Example 2: On the basis of Example 1, as Figure 2 and Figure 7As shown, it also includes a baffle 5 and a first buckle 31. Four baffles 5 are symmetrically installed on the pressing plate 4. The baffles 5 are distributed on both sides of the first sliding shaft 51. The baffles 5 can protect key internal components such as the first sliding shaft 51 and the connecting plate 6 from external collision or impact, significantly reducing the risk of damage to internal parts. In addition, the tight connection between the baffle 5 and the pressing plate 4 enhances the overall structural rigidity of the installation component, helps to evenly disperse the pressure borne by the pressing plate 4, and prevents deformation or damage caused by excessive local stress during use. A first buckle 31 is provided at a position on the top of the filter 2 relative to the connecting shaft 32. The first buckle 31 is movably clamped with the sealing cover 3. When the sealing cover 3 is placed on the filter 2, the first buckle 31 will engage with the corresponding structure on the sealing cover 3 to ensure that the sealing cover 3 will not fall off easily and at the same time provides a good sealing effect to prevent liquid leakage.

[0029] During the use of the device, the baffles 5 symmetrically installed on the pressing plate 4 can effectively protect internal components such as the first sliding shaft 51 and the connecting plate 6 from external collision or impact, significantly reducing the frequency of maintenance and replacement of internal parts. The connection between the baffle 5 and the pressing plate 4 enhances the structural rigidity of the entire installation component, helps to evenly disperse the pressure borne by the pressing plate 4, and avoids deformation or damage caused by uneven stress during use. By pressing down the sealing cover 3, the first buckle 31 is clamped with the sealing cover 3 to complete the installation of the sealing cover 3 and ensure the sealing inside the filter 2.

[0030] The above-described embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements, and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
