DETAILED DESCRIPTION

[0026] The following will be combined with the attached embodiment of the utility model Figure 1-4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] A multi-angle rotatable and easily removable oil filter comprises a shell 1, a fixing member 2 is fixedly connected to one side of the inner cavity of the shell 1, both ends of one side of the fixing member 2 are penetrated with bayonet pins 4 distributed at equal intervals, a spring 5 is sleeved on the surface of the bayonet pin 4, both ends of the spring 5 are respectively fixedly connected to the bayonet pin 4 and the fixing member 2, a raised plate 14 is fixedly connected to one side of the fixing member 2, both sides of the raised plate 14 are provided with bayonet grooves 6, one side of the inner part of the bayonet groove 6 is provided with a lock groove 7, an inner end block 9 is inserted into the interior of the fixing member 2, both sides of the inner end block 9 are fixedly connected with bayonet blocks 10, and one end of the two bayonet blocks 10 away from the inner end block 9 is fixedly connected with an outer ring plate 8 located on the outer side of the inner end block 9, and the bayonet blocks 10 are adapted to the bayonet groove 6 and the lock groove 7.

[0028] The specific usage process is as follows: when the filtering effect of the filter paper deteriorates and needs to be replaced, the user can operate as follows, because both ends of the inner cavity of the lock slot 7 can be installed with fixed blocks 10 by the user, so according to the installation position of the block 10, the user rotates the outer ring plate 8 and the inner end block 9 in the opposite direction until the block 10 is rotated to align with the slot 6, so that the block 10 can be taken out from the lock slot 7 and through the slot 6. The following is an explanation of the slot 6, the block 10 and the lock slot 7 on one side, and refer to Figure 3-4When the card block 10 on the corresponding side passes through the card slot 6 and is stuck in the bottom position of the inner cavity of the lock slot 7, the plug hole 11 on the corresponding side is also at the same horizontal position as the card block 10. At this time, the lowest card pin 4 on the corresponding side will be stuck in the corresponding plug hole 11 under the action of the spring 5, and vice versa, the uppermost card pin 4 is stuck in the plug hole 11, thereby positioning and fixing the outer ring plate 8 and the inner end block 9. Since the outer ring plate 8 and the inner end block 9 will rotate during the installation process, the card block 10 on the side opposite to the current side is stuck in the positioning of the inner cavity of the lock slot 7. The uppermost bayonet 4 on this side will be snapped into the corresponding bayonet 4 under the action of the corresponding spring 5, so that the installation of the outer ring plate 8 and the inner end block 9 can be completed. During the installation process, after the block 10 is snapped into the slot 6 and enters the lock slot 7, the bayonet 4 in the middle position will also be snapped into the corresponding socket 11 under the action of the corresponding spring 5. When the outer ring plate 8, the inner end block 9 and the block 10 rotate, the position of the socket 11 will also rotate accordingly, and then the bayonet 4 in the middle position will be squeezed out of the inner cavity of the socket 11, and at the same time The spring 5 on the bayonet 4 is stretched. When the socket 11 on this side rotates downward, the bayonet 4 on the corresponding side and the middle bayonet 4 are squeezed and stretched at the same time until the socket 11 rotates to align with the corresponding bayonet 4 below. At this time, the spring 5 originally in the stretched state will shrink, thereby pulling the bayonet 4 back, so that the bayonet 4 is inserted into the socket 11 to achieve positioning and fixing of the outer ring plate 8 and the inner end block 9. At this time, the card block 10 is not aligned with the card slot 6, so it will not enter the card slot 6, and the positioning of the bayonet 4 When the outer ring plate 8 is disassembled, the outer ring plate 8 is rotated in the opposite direction to that during installation until the block 10 is aligned with the card slot 6, and then the outer ring plate 8 is taken out. At this time, the openings of the fixing part 2 and the inner guard plate 20 are exposed, so that the filter paper 18 can be taken out and the filter paper 18 can be replaced. After replacing the new filter paper 18, the entire filter can be used again, which provides convenience for the user's work and reduces the cost investment.

[0029] Therefore, a multi-angle rotating installation structure design is adopted. The end cover of the oil filter can be installed by rotating it in any direction, and the end cover can also be disassembled by rotating it in any direction. In this way, there will be no restrictions, which provides users with more and more flexible options for disassembly work, improves the user's disassembly and assembly efficiency, and the filter can be used again after replacing the filter paper, reducing maintenance costs and providing convenience for users' work.

[0033] Specifically, the thread groove 15 and the end head 16 are arranged such that the thread groove 15 is installed on the filter by means of a threaded connection, that is, the thread is installed on the inner end block 9. When the filter is installed and used, the end head 16 can extend into the oil pan to ensure that the engine oil can smoothly enter and exit the filter, thereby filtering the engine oil and facilitating the user to disassemble, assemble and replace the filter.

[0034] The top and bottom of one side of the outer ring plate 8 are both provided with a limit slot 12 , and the top and bottom of one side of the fixing member 2 are both provided with a limit pin 13 slidably installed in the inner cavity of the limit slot 12 .

[0035] Specifically, with the setting of the limit slot 12 and the limit pin 13, when the outer ring plate 8 is installed, the limit pin 13 will be stuck in the corresponding limit slot 12, and with the rotation of the outer ring plate 8, the limit pin 13 will also slide in the corresponding limit slot 12, so that the installation of the outer ring plate 8 and the inner end block 9 can be limited, ensuring that the outer ring plate 8 and the inner end block 9 are installed smoothly and quickly, providing convenience for the user's work.

[0036] A tail end block 19 is integrally formed at one end of the housing 1 , and the cross-section of the tail end block 19 is a polygon.

[0037] Specifically, the rear end block 19 is configured such that the shape of the rear end block 19 is similar to a nut, so that the user can use a tool to clamp the rear end block 19, thereby quickly removing the entire filter from the vehicle, providing convenience for the user's disassembly work.

[0038] A ferrule 17 is fixedly connected to one side of the inner cavity of the housing 1 , and a filter paper 18 is inserted into the interior of the ferrule 17 .

[0039] Specifically, the arrangement of the card sleeve 17 and the filter paper 18 is that the card sleeve 17 is fixed on the inner wall of the shell 1, and one end of the filter paper 18 is inserted into the card sleeve 17, so that the card sleeve 17 will not shake in the shell 1 during use, providing convenience for the user's work.

[0040] An inner guard plate 20 is fixedly connected to a side of the fixing member 2 away from the raised plate 14 , and one end of the inner end block 9 is inserted into the inner guard plate 20 .

[0041] Specifically, when the inner guard plate 20 is set, the inner end block 9 will also be inserted into the inner guard plate 20 during installation, so that the inner guard plate 20 can limit the inner end block 9 and the outer ring plate 8, preventing the outer ring plate 8 and the inner end block 9 from shifting to one side, ensuring the stability and tightness of the outer ring plate 8 and the inner end block 9 after installation, and providing convenience for the user's work.
