The turntable 26 is rotatably connected to the middle part of the bottom wall of the cover body 3. The arc-shaped shifting frames 24 are all arranged on the upper side of the turntable 26. The inner wall of the disassembly column 21 is provided with an evenly distributed adjustable arc-shaped shifting frame 24. The mounting mechanism 2 also includes a turntable 26. The turntable 26 is rotatably connected to the middle part of the bottom wall of the cover body 3. The arc-shaped shifting frames 24 are all arranged on the upper side of the turntable 26. The end face is provided with a connecting plate 22, and a pin 23 is provided at one end of the lower side surface of the connecting plate 22 near the center of the cover body 3. The lower end of the pin 23 is located inside the arc-shaped shifting frame 24 adjacent to the lower side. The mounting mechanism 2 also includes a driven bevel gear 25, a support column 28 and an active bevel gear 29. A support column 28 is provided in the middle of the upper side surface of the turntable 26. The outer arc surface fixed sleeve of the support column 28 is provided with a driven bevel gear 25. The top wall of the cover body 3 is rotatably connected to the mounting column 9 through the mounting frame 10. The right end of the outer arc surface of the mounting column 9 is fixed with a driving bevel gear 29. The driving bevel gear 29 is meshed with the driven bevel gear 25. The left end of the outer arc surface of the mounting column 9 is provided with a gear 11. The left end of the upper side wall of the cover body 3 is slidably connected with a sliding column 12. The lower end of the sliding column 12 is provided with a rack plate 13. The strip plate 13 is meshed with the gear 11, and the upper end of the sliding column 12 is fixedly connected to the sleeve 5, and the internal rotation of the sleeve 5 is connected to the rotating shaft 6. The upper and lower sides of the right end of the outer arc surface of the rotating shaft 6 are provided with limiting grooves 61. A limiting column 7 is provided on the left side of the upper side surface of the cover body 3, and a limiting block 71 is provided on the left side of the outer arc surface of the limiting column 7. The limiting block 71 is installed in conjunction with the limiting column 7 adjacent to the left side (the distance between the left side surface of the limiting block 71 and the left inner wall of any limiting groove 61 is greater than the distance between the front and rear sides of the limiting block 71). First, install the mounting ring 1 in the scene where the end cover of the hydraulic filter is used, and then the worker rotates the rotating shaft 6. At this time, the rotating shaft 6 rotates inside the sleeve 5. At this time, the limiting groove 61 is separated from the restriction of the limiting block 71, and then the worker pulls the rotating shaft 6 upward to rotate The shaft 6 drives the sleeve 5 to move upward. At this time, the sliding column 12 drives the rack plate 13 to move upward as the sleeve 5 moves. At this time, under the action of meshing, the gear 11 drives the mounting column 9 to rotate clockwise, thereby driving the active bevel gear 29 to rotate synchronously. At this time, under the action of meshing, the driven bevel gear 25 drives the turntable 26 to rotate through the support column 28, and the turntable 26 drives the arc-shaped shifting frame 24 to rotate clockwise. At this time, as the arc-shaped shifting frame 24 rotates, the pin 23 gradually moves inward as the arc-shaped shifting frame 24 rotates. In this process, the interior of the arc-shaped shifting frame 24 slides and rotates along the arc surface of the adjacent pin 23, and then the pin 23 drives the disassembly column 21 to move inward synchronously through the connecting plate 22. At this time, the disassembly column 21 slides inside the adjacent rotary barrel 27.When it is adjusted to the appropriate position, the worker rotates the shaft 6. At this time, the limit groove 61 on the lower side is stuck on the limit block 71, and the shaft 6 is not easy to slide up and down. The worker holds the cover body 3 and slides it into the interior of the mounting ring 1. At this time, the arc surface of the cover body 3 is tightly fitted with the sealing ring 8 embedded in the sealing groove of the mounting ring 1. Then the worker rotates the shaft 6 again, and then presses the shaft 6 down first. The interior of the mounting mechanism 2 is adjusted in the opposite direction, and the arc-shaped shifting frame 24 rotates counterclockwise. At this time, the pin shaft 23 gradually moves outward with the rotation of the arc-shaped shifting frame 24, and the pin shaft 23 drives the disassembly through the connecting plate 22. The mounting post 21 moves outward synchronously, and the disassembly post 21 slides inside the adjacent rotating barrel 27 until it passes through the two radially adjacent mounting holes 4 in sequence. The worker then rotates the rotating shaft 6, and the upper limit groove 61 is now stuck on the limit block 71, so the rotating shaft 6 is not easy to slide up and down. The installation of the end cover is now completed. When the end cover needs to be removed, the worker only needs to repeat the step of pulling the rotating shaft 6 upward again. The disassembly post 21 in the installation mechanism 2 is disengaged from the mounting hole 4, and the worker can remove the cover body 3, completing the disassembly work, which facilitates the rapid disassembly and installation of the hydraulic filter end cover.

[0028] The working principle of the hydraulic filter end cover provided by the present invention which is convenient for disassembly and assembly is as follows: first, the mounting ring 1 is installed in the scene where the hydraulic filter end cover is used, and then the worker rotates the rotating shaft 6. At this time, the rotating shaft 6 rotates inside the sleeve 5. At this time, the limit groove 61 is free from the restriction of the limit block 71. Then the worker pulls the rotating shaft 6 upward, and the rotating shaft 6 drives the sleeve 5 to move upward. At this time, the sliding column 12 drives the rack plate 13 to move upward with the movement of the sleeve 5. At this time, under the meshing action, the gear 11 drives the mounting column 9 to rotate clockwise, and the sleeve 5 is moved upward. And drive the active bevel gear 29 to rotate synchronously. At this time, under the meshing action, the driven bevel gear 25 drives the turntable 26 to rotate through the support column 28, and the turntable 26 drives the arc-shaped shifting frame 24 to rotate clockwise. At this time, as the arc-shaped shifting frame 24 rotates, the pin 23 gradually moves inward with the rotation of the arc-shaped shifting frame 24. In this process, the interior of the arc-shaped shifting frame 24 slides and rotates along the arc surface of the adjacent pin 23, and then the pin 23 drives the disassembly column 21 to move inward synchronously through the connecting plate 22. At this time, the disassembly column 21 is in the adjacent rotary barrel. 27 slides inside and is adjusted to the appropriate position. The worker rotates the shaft 6. At this time, the limit groove 61 on the lower side is stuck on the limit block 71. The shaft 6 is not easy to slide up and down. The worker holds the cover body 3 and slides it into the interior of the mounting ring 1. At this time, the arc surface of the cover body 3 fits tightly with the sealing ring 8 embedded in the sealing groove of the mounting ring 1. Then the worker rotates the shaft 6 again, and then presses the shaft 6 down first. The interior of the mounting mechanism 2 is adjusted in the opposite direction, and the arc-shaped frame 24 rotates counterclockwise. At this time, the pin 23 gradually moves outward with the rotation of the arc-shaped frame 24, and the pin 2 3. The disassembly column 21 is driven to move outward synchronously through the connecting plate 22. At this time, the disassembly column 21 slides inside the adjacent rotating barrel 27 until it passes through the two radially adjacent mounting holes 4 in sequence. Then the worker rotates the rotating shaft 6. At this time, the upper limit groove 61 is stuck on the limit block 71, and the rotating shaft 6 is not easy to slide up and down. At this time, the installation of the end cover is completed. When the end cover needs to be disassembled, it is only necessary to repeat the step of pulling the rotating shaft 6 upward again. The disassembly column 21 in the installation mechanism 2 is separated from the mounting hole 4, and the worker can remove the cover body 3 to complete the disassembly.
