[0002] Oil filter, also known as oil filter. It is used to remove impurities such as dust, metal particles, carbon sediments and soot particles in the oil to protect the engine. Oil filters are divided into full-flow type and split-flow type. The full-flow filter is connected in series between the oil pump and the main oil channel, so it can filter all the lubricating oil entering the main oil channel. The split-flow filter is connected in parallel with the main oil channel and only filters part of the lubricating oil sent by the oil pump.

[0003] The existing oil filter is connected to the oil pipeline through threads to filter the oil, and the filter is mostly cylindrical in structure, which causes slippage between the palm and the filter housing when tightening or removing, resulting in the phenomenon of being unable to remove or poor sealing after installation. Therefore, the existing filter will be provided with multiple facets at the tail to cooperate with the external special wrench for operation, but the space inside the frame is limited, resulting in the limited range of operation of the wrench during installation. If you forget to bring the wrench, you cannot install or remove the work, which is extremely inconvenient. At the same time, the filter is only installed on the pipeline through threads, which increases the probability of the filter loosening due to bumps during the driving of the car.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 3 As shown, an oil filter that is easy to disassemble includes a shell body 1, a corrugated surface 11 is arranged below the outer surface of the shell body 1, a top cover 2 is pressed on the top of the shell body 1, an oil outlet 21 is opened at the center of the top of the top cover 2, and oil inlets 22 are evenly opened on the surface of the top cover 2 with the center as the center of the circle, the top cover 2 seals the top of the shell body 1, so that the oil can only flow through the oil inlet 22 and the oil outlet 21, a check valve plate 3 is installed on the inner surface of the top cover 2, and the check valve plate 3 is placed below the oil inlet 22 to prevent the oil from flowing back, a filter element 4 is arranged inside the shell body 1, the oil outlet 21 is connected with the inside of the filter element 4, the oil flows out through the oil inlet 22 and then is filtered by the filter element 4, and finally flows out through the oil outlet 21 to filter the oil.

[0025] Please refer to Figure 1 and Figure 3 As shown, a fixing block 5 is symmetrically arranged above the outer surface of the shell 1, and a connecting rod A6 is installed on the outer side of the fixing block 5 through a pin shaft, a boss 7 is symmetrically arranged below the outer side of the shell 1, and the boss 7 is placed directly below the fixing block 5, and a track bar 71 is symmetrically arranged on the outer side of the boss 7. Limiting grooves 72 are evenly arranged on the surface of the two track bars 71 that are close to each other, and sliders 8 are slidably installed on the surfaces of the two track bars 71. The track bars 71 can ensure that the slider 8 can only move up and down, and a connecting rod B9 is installed on the upper outer side of the slider 8 through a pin shaft, and the end of the connecting rod B9 is installed on the end of the connecting rod A6 through a pin shaft. When the slider 8 moves up, the distance between the fixing block 5 is reduced. At this time, the connection between the connecting rod A6 and the connecting rod B9 is offset outward to increase the fulcrum. Conversely, during transportation, the connecting rod A6 and the connecting rod B9 can be placed on the same vertical line to save transportation space.

[0026] Please refer to the Figure 3 and Figure 4 As shown, mounting holes 81 are symmetrically provided on both sides of the slider 8, and a pressing block 82 is slidably installed inside the mounting hole 81. The pressing block 82 exceeds the outer surface of the slider 8 to facilitate pressing the slider 8 from the outside. A connecting rod 83 is provided on the side where the two pressing blocks 82 are close to each other. The connecting rod 83 passes through the inner wall of the mounting hole 81, and a spring 84 is sleeved on the surface of the connecting rod 83. The spring 84 is placed inside the mounting hole 81, and one end of the spring 84 contacts the inner surface of the pressing block 82. The elastic force of the spring 84 is used to make the pressing block 82 be pushed outward, and then when no force is applied, the wedge block 85 remains in cooperation with the corresponding limit groove 72 to keep it fixed.

[0027] Among them, a wedge block 85 is horizontally arranged at one end of the connecting rod 83 away from the pressing block 82. The wedge block 85 is placed inside the slider 8. The wedge block 85 is adapted to the internal size of the limiting groove 72. The matching direction of the two can ensure that there is no obstruction when the slider 8 moves up, so as to improve the convenience during operation.

[0028] Please refer to Figure 3 As shown, a limiting block 73 is provided at the bottom of the two track bars 71 to limit the slider 8 to prevent it from falling off when sliding down.

[0029] Working principle: During installation, the thread inside the top cover 2 can be used to keep the filter connected to the oil pipeline. The oil enters through multiple oil inlets 22, then passes through the filter element 4 and flows out from the oil outlet 21 to filter the oil. During installation or removal, the housing 1 can be rotated by the cooperation of the wrench and the multi-corrugated surface 11. If there is no ratchet wrench, the slider 8 can be controlled to move toward the top cover 2. The inclined surface of the wedge block 85 and the inclined groove of the limit groove 72 can ensure that the slider 8 will not be blocked when it moves up. When the slider 8 moves up, the distance from the fixed block 5 is reduced. The connection between the connecting rod A6 and the connecting rod B9 is small, so that the connection between the connecting rod A6 and the connecting rod B9 can be raised outward to provide a fulcrum for rotating the shell 1, thereby facilitating the disassembly of the shell 1. Conversely, the force during tightening can be increased to ensure the sealing. When the filter is installed in place, the connection between the connecting rod A6 and the connecting rod B9 can be controlled to move outward to abut against the inner wall of the frame to improve the stability of the filter during driving. Conversely, when the control slider 8 moves downward, the pressing block 82 can be pressed to make the wedge block 85 move inward and not cooperate with the limiting groove 72, so that the slider 8 can slide freely.

[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
