[0026] The clamping assembly 2 is slidably assembled on the lifting assembly 1, and the filter body 3 is detachably assembled on the clamping assembly 2;

[0027] The clamping assembly 2 includes a mounting seat 21 assembled on the lifting assembly 1, a main frame 26 is mounted on the side of the mounting seat 21, and two oppositely arranged limit frames 27 are mounted on the side of the main frame 26. The two limit frames 27 are U-shaped and the sides thereof are both threadedly connected with an adjusting screw 28. The two limit frames 27 form a rectangular clamping space, and the filter body 3 is clamped between the two limit frames 27;

[0028] A base plate 29 is also mounted on the side of the mounting seat 21 , and shock absorbing blocks 210 are protrudingly provided at the four corners of the base plate 29 .

[0029] In this embodiment, when the filter body 3 of the present application is adjusted in position, due to the limitation of the side limit rod 16 and the screw rod 13, the filter body 3 can be adjusted in position over a long stroke during movement and adjustment, and the overall movement is stable, so that the filter body 3 can adapt to different application requirements. At the same time, the lifting assembly 1 can provide precise lifting position control, so that the lifting process of the filter body 3 can be fine-tuned as needed. This precise control can ensure that the filter body 3 stops at a specific position and can maintain a stable working state, ultimately making the filter body 3 of the present application more applicable in terms of adjustability.

[0030] Furthermore, in actual use, through the mutual cooperation of multiple components in the clamping assembly 2, the user can press one side of the filter body 3 between the two limit frames 27 and make the bottom of the filter body 3 between the four shock-absorbing blocks 210, and cooperate with the encirclement of the limit frames 27 and the tight abutment of the adjusting screw 28 against the side wall of the filter body 3, thereby realizing the rapid assembly of the filter body 3 in the clamping assembly 2; the shock-absorbing blocks 210 can also provide buffering protection for the side of the filter body 3. Compared with the fixed installation method in the cited document, the filter body 3 of the present application can be quickly and easily installed on the clamping assembly 2. At the same time, the clamping assembly 2 can adapt to the installation of filter bodies 3 of different sizes and shapes, thereby flexibly responding to different installation and use requirements, and the overall use is more convenient.

[0031] Specifically, refer to Figure 1 and Figure 4 The shock absorbing block 210 is made of rubber material and each shock absorbing block 210 is threadedly connected with a pin shaft, and one end of the pin shaft passes through the base plate 29 and extends to be threadedly connected with the mounting seat 21 .

[0032] In this embodiment, the pin shaft can be used to install the shock-absorbing block 210 on the mounting seat 21. After the shock-absorbing block 210 has been used for a period of time, the user can disassemble and replace the shock-absorbing block 210. The shock-absorbing block 210 can effectively reduce the transmission of external vibrations to the filter body 3. Combined with the surrounding of the filter body 3 by the limit frame 27, when the filter body 3 is subjected to external vibrations, the shock-absorbing block 210 can absorb and disperse the vibration energy to reduce its impact on the filter body 3. At the same time, when the size of the filter body 3 changes, the shock-absorbing block 210 can be adapted to change the size accordingly.

[0033] Specifically, refer to Figure 1 and Figure 4 The side of the mounting seat 21 is equipped with two positioning bolts 24 and a positioning seat 22, wherein an adjacent positioning seat 22 and a positioning bolt 24 are arranged as a group, and the outside of the two positioning bolts 24 are both sleeved with a slider seat 23, and the slider seat 23 is provided with a slot and can slide radially on the outside of the positioning bolt 24 perpendicular to the mounting seat 21.

[0034] In this embodiment, the slider seat 23 can be used to adjust the position horizontally on the positioning bolt 24. The user moves one end of the slider seat 23 to one side of the filter body 3 until it is tightly against the filter body 3, and then fixes the slider seat 23. The filter body 3 can be further limited and clamped by two oppositely arranged slider seats 23.

[0035] Specifically, refer to Figure 1 and Figure 4 One end of the positioning bolt 24 passes through the slider seat 23 and is threadedly connected with an adjusting nut 25 . One end of the adjusting nut 25 abuts against the slider seat 23 , and the bottom of the slider seat 23 slides on the positioning seat 22 at the same time.

[0036] In this embodiment, when adjusting the slider seat 23, the user can loosen the adjusting nut 25 so that the slider seat 23 can be laterally displaced outside the positioning bolt 24. When the ends of the two slider seats 23 abut against the side walls of the filter body 3, the user then tightens the adjusting nut 25 again so that the slider seat 23 is fixed at the end of the positioning bolt 24, thereby completing the clamping and limiting of the filter body 3 by the two slider seats 23.

[0037] Specifically, refer to Figure 1-2 The lifting assembly 1 includes a screw seat 11, a bearing member 12 is assembled in the screw seat 11, a screw rod 13 is rotatably arranged in the bearing member 12, and a sliding seat 15 is engaged with the external thread of the screw rod 13. The screw seat 11 is U-shaped and two side limit rods 16 are provided on both sides thereof. The two side limit rods 16 are respectively arranged on one side of the screw rod 13 and penetrate the sliding seat 15 at the same time.

[0038] In this embodiment, when adjusting the position of the filter body 3, the user can assemble the filter body 3 on the clamping assembly 2, and at the same time assemble the clamping assembly 2 on the sliding seat 15 using bolts; the user controls the screw rod 13 to rotate, and at this time, when the screw rod 13 is rotating, the two side limit rods 16 cooperate to limit the sliding seat 15 sideways, so that the sliding seat 15 can slide radially outside the screw rod 13. At this time, the user can achieve different position adjustments of the sliding seat 15 by adjusting the number of rotations and the positive and negative directions of the screw rod 13, and further achieve different precise position adjustments of the filter body 3.

[0039] Specifically, refer to Figure 1-2 A reciprocating motor 14 is also mounted on one side of the screw seat 11. The output end of the reciprocating motor 14 penetrates the screw seat 11 and extends to be connected to one end of the screw rod 13. The sliding seat 15 is connected to the mounting seat 21 through a bolt.

[0040] In this embodiment, the reciprocating motor 14 can be used to control the rotation of the screw rod 13, thereby realizing precise control of the number of rotations of the screw rod 13, so as to achieve precise position control of the sliding seat 15. In a preferred embodiment, the reciprocating motor 14 can also be replaced by a handle to realize manual rotation control of the screw rod 13.

[0041] The utility model is an adjustable filter that is easy to install:

[0042] Step 1: When the user needs to assemble the filter body 3, by pressing one side of the filter body 3 between the two limit frames 27, and making the bottom of the filter body 3 between the four shock absorbing blocks 210, the user can then turn the multiple adjusting screws 28 in sequence until the end of the adjusting screw 28 abuts against the side wall of the filter body 3. At this time, the clamping and limiting of the filter body 3 can be achieved by cooperating with the surrounding of the limit frames 27, and the shock absorbing blocks 210 can also provide buffering protection for the side of the filter body 3;

[0043] Step 2: After the user adjusts the adjusting screw 28 to complete the initial limiting of the filter body 3, the user can loosen the adjusting nut 25 so that the slider seat 23 can be laterally displaced outside the positioning bolt 24. At this time, the user controls the two slider seats 23 to move toward one side of the filter body 3 until the ends of the two slider seats 23 abut against the side wall of the filter body 3. Then the user tightens the adjusting nut 25 again so that the slider seat 23 is fixed at the end of the positioning bolt 24. At this time, the two slider seats 23 limit the side wall of the filter body 3, and the clamping and limiting of the filter body 3 can be further completed;

[0044] Step 3: After the filter body 3 is quickly assembled on the clamping assembly 2, the user can connect the power supply to the reciprocating motor 14 so that the output end of the reciprocating motor 14 drives the screw 13 to rotate. When the screw 13 rotates, the two side limit rods 16 cooperate to limit the sliding seat 15, so that the sliding seat 15 can slide radially outside the screw 13. At this time, the user can adjust the position of the sliding seat 15 by adjusting the number of rotations and the positive and negative directions of the reciprocating motor 14. By assembling the clamping assembly 2 on the filter body 3, the position of the filter body 3 can be further adjusted.
