The outer wall is rotatably connected to the inner wall of the cover body 8 through a bearing, and the outer wall of the threaded column 10 is threadedly connected with a cross column 11, and the threaded column 10 drives the cross column 11 to move, and the outer wall of the cross column 11 is fitted with a sealing ring 12, and the cross column 11 moves in the sealing ring 12, and the sealing ring 12 increases the sealing between the cross column 11 and the shell 1, and the outer wall of the sealing ring 12 is fixedly connected to the inner wall of the shell 1, and the side of the cross column 11 away from the rotating knob 9 is fixedly connected with a clamping plate 13, and the cross column 11 drives the clamping plate 13 to move, and the clamping plate 13 contacts the filter element 6 to fix the filter element 6, and the outer wall of the cross column 11 away from the clamping plate 13 is fixedly connected with a connecting block 14, and the cross column 11 drives the connecting block 14 to move, and the inner wall of the connecting block 14 is slidably connected with a sliding rod 15, and the connecting block 14 slides in the sliding rod 15 to limit the cross column 11, and the end of the sliding rod 15 is fixedly connected to the inner wall of the cover body 8;

[0026] In the specific implementation process, it is worth pointing out that the external non-return fuel enters the interior of the housing 1 through the oil inlet pipe 4, and the non-return fuel is discharged through the oil discharge pipe 5 after filtering. The non-return fuel is filtered by the filter element 6, and the staff rotates the rotary knob 9, and the rotary knob 9 drives the threaded column 10 to rotate, and the threaded column 10 drives the cross column 11 to move, and the cross column 11 moves in the sealing ring 12, and the sealing ring 12 increases the sealing between the cross column 11 and the housing 1, and the cross column 11 drives the clamping plate 13 to move, and the clamping plate 13 contacts the filter element 6 to fix the filter element 6, and the cross column 11 drives the connecting block 14 to move, and the connecting block 14 slides in the sliding rod 15 to limit the cross column 11, so as to fix the filter element 6;

[0027] Furthermore, the top of the inner wall of the housing 1 and the bottom of the inner wall of the top cover 2 are respectively connected with sealing rings 25, and the sealing rings 25 increase the sealing between the housing 1 and the top cover 2;

[0028] In the specific implementation process, it is worth pointing out that the sealing ring 25 increases the sealing between the housing 1 and the top cover 2;

[0029] Furthermore, the outer wall of the housing 1 is fixedly connected with a mounting plate 7, and the filter is installed at a designated position by a worker through a mounting hole inside the mounting plate 7. The mounting hole is circular in shape, and there are four mounting holes, which are distributed at the left and right front positions of the mounting plate 7.

[0030] In the specific implementation process, it is worth pointing out that the filter is installed at the designated position by the staff through the mounting holes inside the mounting plate 7. The mounting holes are circular in shape and there are four mounting holes, which are distributed at the left and right front positions of the mounting plate 7.

[0031] Furthermore, a cross column 23 is fixedly connected to the bottom of the inner wall of the shell 1, and the cross column 23 is fixedly connected to the blocking block 21 through a second spring 24. The blocking block 21 drives the second spring 24 to stretch. When the check fuel is filtered, the blocking block 21 is no longer affected by the gravity of the check fuel. The second spring 24 bounces the blocking block 21 back to its initial position, closing the bottom of the shell 1 to prevent backflow. The material of the second spring 24 is carbon spring steel. The elastic coefficient of the second spring 24 is selected according to actual needs to meet the work. A connecting rod 22 is fixedly connected to the bottom of the blocking block 21. The connecting rod 22 passes through the cross column 23 and is movably connected to the cross column 23. When the filtered check fuel flows to the position of the blocking block 21, the blocking block 21 is affected by the gravity of the check fuel, and the blocking block 21 descends to open the bottom of the shell 1. The blocking block 21 drives the connecting rod 22 to move, and the connecting rod 22 slides in the cross column 23.

[0032] In the specific implementation process, it is worth pointing out that the material of the second spring 24 is carbon spring steel, and the elastic coefficient of the second spring 24 is selected according to actual needs to meet the work. When the filtered check fuel flows to the position of the blocking block 21, the blocking block 21 is subjected to the gravity of the check fuel, and the blocking block 21 drops to open the bottom of the shell 1. The blocking block 21 drives the connecting rod 22 to move, and the connecting rod 22 slides in the cross column 23. The blocking block 21 drives the second spring 24 to stretch. When the check fuel is filtered, the blocking block 21 is no longer subjected to the gravity of the check fuel. The second spring 24 passes, and the blocking block 21 is rebounded to the initial position, and the bottom of the shell 1 is closed to avoid backflow.

[0033] Furthermore, the top of the housing 1 is fixedly connected with a top cover 2 by means of bolts 3. The staff rotates the bolts 3 to remove the top cover 2 and place the filter element 6 inside the housing 1. The staff then rotates the bolts 3 in the opposite direction to re-fix the top cover 2 to install the filter element 6 or replace the filter element 6.

[0034] In the specific implementation process, it is worth pointing out that the staff can remove the top cover 2 by turning the bolt 3, and place the filter element 6 inside the housing 1. The staff then turns the bolt 3 in the opposite direction, re-fixes the top cover 2, and installs the filter element 6, or replaces the filter element 6.

[0035] Specifically, first the staff rotates the bolt 3 to remove the top cover 2 and place the filter element 6 inside the housing 1. The staff then rotates the bolt 3 in the opposite direction to re-fix the top cover 2 to install the filter element 6. After completion, the staff rotates the rotating knobs 9 on both sides, and the rotating knobs 9 drive the threaded columns 10 to rotate, and the threaded columns 10 drive the cross columns 11 to move. The cross columns 11 move in the sealing ring 12, and the cross columns 11 drive the connecting blocks 14 to move. The connecting blocks 14 slide in the sliding rods 15, and the cross columns 11 drive the clamping plates 13 to move. The clamping plates 13 contact the filter element 6 to fix the filter element 6. After completion, the staff stops rotating the rotating knob 9. When the staff rotates the rotating knob 9 in the opposite direction, the filter element 6 is released, and then the staff passes through the mounting plate 7. The internal mounting hole installs the filter to the specified position. When the check fuel needs to be filtered, the external check fuel enters the interior of the housing 1 through the oil inlet pipe 4, and the check fuel is filtered through the filter element 6. When the filtered check fuel flows to the position of the blocking block 21, the blocking block 21 is affected by the gravity of the check fuel, and the blocking block 21 descends to open the bottom of the housing 1. The blocking block 21 drives the connecting rod 22 to move, and the connecting rod 22 slides in the cross column 23. The blocking block 21 drives the second spring 24 to stretch, and the filtered check fuel is discharged through the oil drain pipe 5. After the filtering is completed, the blocking block 21 is no longer affected by the gravity of the check fuel. The second spring 24 passes and bounces the blocking block 21 back to the initial position, closing the bottom of the housing 1 to avoid backflow.

[0036] Embodiment 2, by Figure 1-5It can be seen that the inner wall of the housing 1 is fixedly connected with a sleeve 19. When the filter element 6 needs to be taken out of the housing 1, the top cover 2 leaves the top of the filter element 6. At this time, the first spring 18 starts to rebound, and the column 17 is driven to move by the elastic force. The sleeve 19 is fixedly connected with the column 17 through the first spring 18.

[0037] In the specific implementation process, it is worth pointing out that the material of the first spring 18 is carbon spring steel, and the elastic coefficient of the first spring 18 is selected according to actual needs and meets the work requirements. When the filter element 6 needs to be taken out from the housing 1, the top cover 2 leaves the top of the filter element 6. At this time, the first spring 18 begins to rebound, and the column 17 is driven to move by elastic force, and the column 17 moves in the sleeve 19, and the column 17 drives the slider 20 to move, and the sliders 20 on both sides slide in the slide grooves on both sides of the sleeve 19, and the column 17 drives the cross plate 16 to rise, and the cross plate 16 drives the filter element 6 to move, and the top of the filter element 6 is pushed out of the interior of the housing 1, so that the staff can take the filter element 6 out of the interior of the housing 1.

[0038] Specifically, when the filter element 6 needs to be taken out from the housing 1, the top cover 2 leaves the top of the filter element 6. At this time, the first spring 18 begins to rebound, and the column 17 is driven to move by the elastic force. The column 17 moves in the sleeve 19, and the column 17 drives the slider 20 to move.
