AI Technical Summary
When the filter element vibrates inside the housing for a long time, it may cause looseness at the connection between the housing and the end cap, resulting in leakage at the connection, which makes the filter element weaken the fluid filtration effect.
A double sealing filter element is designed, and double sealing of the outer shell is achieved by providing a first and a second sealing groove at both ends of the shell and a first and a second sealing ring in the groove. In addition, by symmetrically placing the push rod on the first and second end caps, and combining the limiting block and the locking mechanism, the fixing of the first and second end caps is quickly fixed and released, preventing leakage at the connection from being caused by prolonged working. Meanwhile, by providing mounting slide rods and damping springs on the first and second end covers, vibrations generated when the filter element body is operated are absorbed, and the stability of the filter element body is maintained.
Through the dual seal design and push rod limit locking mechanism, leakage at the connection between the shell and the end cover is effectively prevented, and the filtering effect of the filter element is maintained; vibration is absorbed through the damping spring to ensure that the filter element body remains stable during operation.

[0027] The locking mechanism includes a sliding plate 22, which is slidably arranged inside the fixed box 20, a limit block 21 is fixedly arranged on one side of the sliding plate 22, a fixing groove is arranged at one end of the push rod 19 corresponding to the position of the limit block 21, a guide slide bar is slidably arranged in a circular perforation on one side of the sliding plate 22, and the guide slide bar is fixed inside the fixed box 20, a return spring 23 is fixedly arranged between one side of the sliding plate 22 and one side of the inside of the fixed box 20, and a rectangular perforation is arranged at the upper end of the fixed box 20 corresponding to the position of one end of the push rod 19. When in use, when it is necessary to fix the first end cover 13 and the second end cover 14, The two push rods 19 on one side of the first end cover 13 and the second end cover 14 are respectively inserted into the rectangular through-holes at the upper ends of different fixed boxes 20, and at the same time, one end of the push rod 19 is chamfered so that one end of the push rod 19 pushes the sliding plate 22 to slide on the guide slide rod. When one side of the limit block 21 is aligned with the fixed groove on one side of the push rod 19, the sliding plate 22 drives the limit block 21 back to the initial position under the action of the reset spring 23, so that the limit block 21 moves into the fixed groove, thereby fixing the first end cover 13 and the second end cover 14. One side of the sliding plate 22 is provided with a pushing component for quickly releasing the fixation of the first end cover 13 and the second end cover 14.
[0028] The pushing assembly includes a push rod 24, which is fixed on one side of the sliding plate 22.

When in use, the filter element main body 12 is installed into the interior of the outer shell 11, and then the first end cover 13 and the second end cover 14 are installed, so that the plurality of damping springs 18 are compressed. When the filter element main body 12 is vibrated during operation, the plurality of damping springs 18 can absorb the vibration, so that the filter element main body 12 remains stable during operation.
[0035] The above embodiment discloses a double-sealed filter element, wherein, when in use, the filter element body 12 is installed inside the housing 11, and then the first end cover 13 and the second end cover 14 are installed to both ends of the housing 11, and the first sealing ring 15 and the second sealing ring 16 facilitate double-layer sealing of the inside of the housing 11, and at the same time, two push rods 19 on one side of the first end cover 13 and the second end cover 14 are respectively inserted into the rectangular perforations at the upper ends of different fixed boxes 20, and at the same time, one end of the push rod 19 is chamfered, so that one end of the push rod 19 pushes the sliding plate 22 to slide on the guide slide rod, and when one side of the limit block 21 is aligned with the fixed groove on one side of the push rod 19, the sliding plate 22 is pushed under the action of the reset spring 23. 2 drives the limit block 21 back to the initial position, so that the limit block 21 moves into the fixing groove, thereby fixing the first end cover 13 and the second end cover 14. When the filter element body 12 is subjected to vibration during operation, the plurality of damping springs 18 can absorb the vibration, so that the filter element body 12 remains stable during operation. When it is necessary to release the first end cover 13 or the second end cover 14, the mounting ring 26 is rotated in two directions, and the mounting ring 26 drives the plurality of guide bevel blocks 25 to rotate. The guide bevel blocks 25 cooperate with the push rod 24, so that the push rod 24 pushes the sliding plate 22 to move, and the sliding plate 22 drives the limit block 21 to be separated from the fixing groove, thereby removing the first end cover 13 and the second end cover 14.
