[0025] The following will be combined with the attached embodiment of the present 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

[0026] A rotary oil filter comprises an outer shell 1, a cover 2 is embedded and fixedly connected to one side of the outer shell 1, four slide grooves 3 are opened and closed on one side of the cover 2, a limiting slide rod is fixedly connected to one side of the inner cavity of the slide groove 3, a push block 5 is slidably installed on the surface of the limiting slide rod, a spring 6 is sleeved on the surface of the limiting slide rod, and the two ends of the spring 6 are respectively fixedly connected to the push block 5 and the inner wall of the slide groove 3, a docking hole 8 is opened at the center of one side of the cover 2, and an oil pipe is threadedly installed in the inner cavity of the docking hole 8.

[0027] The specific use process is as follows: first, put the filter element 14 into the shell 1, then align the cover 2 with the opening of the shell 1, and then put the shell 1 and the cover 2 together into a special device for compression processing, and die-cast the cover 2 on the shell 1, so that the cover 2 can be firmly fixed on the shell 1, wherein the cover 2 can prevent the filter element 14 from falling, and can also play a role in pressing the filter element 14 with the cooperation of the pressing block 13, and can play a role in positioning the filter element 14 while ensuring that the filter element 14 can work normally, providing convenience for the user, and the filter production is completed. This is the prior art, and the specific details are not described in detail herein. It should be noted that the threaded tube 9 is installed on the vehicle, that is, the oil pipe composed of the threaded tube 9 and the baffle 10 is installed on the vehicle in advance. During installation, the user holds the filter in his hand, that is, holds the filter in his hand and aligns it with the threaded tube 9, and aligns the docking hole 8 with the threaded tube 9, and then ensures that the end of the threaded tube 9 is inserted into the docking hole 8, and then rotates the housing 1. Since the threaded tube 9 and the docking hole 8 are threadedly connected, the housing 1 can be installed on the threaded tube 9 during the rotation, and then the entire housing can be installed. The filter is installed on the vehicle, wherein during the rotation of the housing 1, the housing 1 will move toward the baffle 10, and during the movement of the housing 1, the baffle 10 will first contact the baffle 10, and then under the extrusion of the baffle 10, the push block 5 will be squeezed into the inner cavity of the slide groove 3. During the extrusion, the push block 5 will slide on the surface of the rod 4, and the slider 17 will also slide in the inner cavity of the slide hole 16. At the same time, the push block 5 will also compress the spring 6, and then the housing 1 continues to rotate and move, and the push block 5 will continue to be squeezed until the card block 12 on the baffle 10 is inserted into the corresponding card slot 7, thereby achieving The positioning of the threaded tube 9 can prevent the threaded tube 9 from moving randomly during use, and can also improve the stability of the entire filter operation, providing convenience for the user's work. At this time, with the cooperation of the spring 6 and the push block 5, a reverse thrust will be provided to the filter according to the axial direction of the filter, so that the filter will not move randomly without the intervention of external force, and the filter will not loosen, thereby ensuring the stability of the filter during operation, and the outer shell 1 is not easy to loosen, and it is not easy to slip, thereby improving the service life of the threaded tube 9 and the cover 2, and the filter is now installed.

[0028] Therefore, a structural design is adopted to increase the pre-tightening force of the filter. After the filter is installed and fixed, the structure will provide a reverse thrust to the filter according to the axial direction of the filter. In this way, the filter will not move at will without the intervention of external force, and the filter will not loosen, thus ensuring the stability of the filter during operation. It can also play a certain sealing role, reduce oil leakage, and provide convenience for users' work.

[0029] One side of the cover 2 is provided with four clamping grooves 7 located outside the slide groove 3 , and one side of the baffle 10 is fixedly connected with a clamping block 12 adapted to the clamping grooves 7 .

[0030] Specifically, with the arrangement of the slots 7 and the blocks 12, after the threaded tube 9 is installed, the multiple blocks 12 on the baffle 10 will also be correspondingly inserted into the slots 7 on the cover 2, thereby realizing the positioning of the threaded tube 9, preventing the threaded tube 9 from moving freely during use, and also improving the working stability of the entire filter, providing convenience for the user's work.

[0031] A retaining ring 11 is fixedly connected to one end of the shell 1, and the retaining ring 11 is fixedly connected to the edge of the cover 2. A plurality of pressing blocks 13 are fixedly connected to the side of the cover 2 facing the inner cavity of the shell 1. The inner cavity of the shell 1 is provided with a filter element 14 adapted to the pressing blocks 13.

[0032] Specifically, with the arrangement of the pressing blocks 13 and the filter element 14, after the filter element 14 is placed and the cover 2 is installed on the housing 1, the multiple pressing blocks 13 will also be pressed tightly on the filter element 14, which can position the filter element 14 while ensuring that the filter element 14 can work normally, providing convenience for users.

[0033] An end block 15 is fixedly connected to one end of the housing 1 away from the cover 2 , and the outer surface of the end block 15 is polygonal.

[0034] Specifically, the end block 15 is configured such that the outer surface of the end block 15 is configured as a polygon, so that the end block 15 can be easily removed by the user by rotating it using a tool, just like a nut, thereby providing convenience for the user's disassembly work.

[0035] The limiting slide bar includes a rod 4 fixedly connected to the inner wall of the slide groove 3, one end of the rod 4 located in the inner cavity of the push block 5 is fixedly connected to a slide block 17, and one side of the push block 5 is provided with a slide hole 16 adapted to the rod 4 and the slide block 17.

[0036] Specifically, the setting of the limit slide bar is used for the sliding work of the push block 5, and can also play a role of limiting and guiding the sliding of the push block 5, thereby ensuring the sliding stability of the push block 5 and providing convenience for the user's work.

[0037] The oil pipe comprises a threaded pipe 9 threadably mounted in the docking hole 8 , and a baffle 10 matched with the push block 5 is fixedly connected to one side of the surface of the threaded pipe 9 .
