DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.

[0024] See also Figure 1-3 A high-strength filter screen for a silencer comprises a connecting frame 1, a screen frame 2 and a filter screen 3 fixedly connected to the inner side of the screen frame 2. A supporting structure for enhancing the structural stability of the filter screen 3 is provided on the right side of the screen frame 2.

[0025] like Figure 1 As shown, the supporting structure includes two brackets 4 fixedly connected to the right side of the net frame 2, an elastic telescopic rod 5 fixedly connected to the right side wall of the bracket 4, a connecting plate 6 fixedly connected to the piston rod of the elastic telescopic rod 5, a connecting rod 7 fixedly connected to the other side of the connecting plate 6, and an activated carbon plate 8 fixedly connected to the other end of the connecting rod 7.

[0026] Using activated carbon board 8 to support filter 3 can bring a series of significant benefits. First, activated carbon board 8 itself has good stability and strength, which can effectively support filter 3, ensure its stability, and prevent filter 3 from being deformed or shifted due to external force or internal airflow. This can not only extend the service life of filter 3, but also ensure that filter 3 always remains in the best working state, thereby improving the filtering effect. Secondly, activated carbon board 8 has a developed microporous structure and a high specific surface area, which enables it to adsorb more organic molecules and harmful gases. When air passes through filter 3, activated carbon board 8 can adsorb and remove pollutants such as odor and harmful gases, further improving the cleanliness of the air.

[0027] A connection component for connecting to the connection frame 1 is provided on the left side of the connection frame 1 .

[0028] It should be noted that a sliding groove is opened on the inner side of the connecting plate 6, and a sliding rod 9 is slidably connected to the inner side of the sliding groove of the connecting plate 6. The left end of the sliding rod 9 is fixedly connected to the right side wall of the net frame 2, and the right end of the sliding rod 9 is fixedly connected to the inner right side wall of the corresponding bracket 4.

[0029] The two brackets 4 are fixedly connected to the top and bottom of the right side of the screen frame 2 respectively, a connecting strip 10 is fixedly connected between the opposite sides of the two connecting rods 7, and the left side wall of the activated carbon plate 8 is in contact with the filter screen 3.

[0030] The connecting assembly includes an installation cavity 11 respectively opened at the inner top and inner bottom of the connecting frame 1, a limit frame 12 fixedly connected to the inner side of the installation cavity 11, a threaded shaft 13 rotatably connected to the inner side of the limit frame 12, a threaded block 14 threadedly connected to the outer side of the threaded shaft 13, a positioning bolt 15 fixedly connected to one side of the threaded block 14, and a positioning block 16 penetrated through the other end of the positioning bolt 15.

[0031] The two positioning blocks 16 are fixedly connected to the top and bottom of the left side of the screen frame 2 respectively. The right side wall of the connecting frame 1 is provided with two sockets adapted to the positioning blocks 16 , and the sockets are connected to the corresponding installation cavities 11 .

[0032] The top limiting frame 12 is fixedly connected to the inner top wall of the top installation cavity 11 , and the bottom limiting frame 12 is fixedly connected to the inner bottom wall of the bottom installation cavity 11 .

[0033] In addition, the length and width of the threaded block 14 are respectively equal to the length and width of the interior of the limit frame 12, so that the threaded block 14 is limited by the limit frame 12. The upper surface of the upper positioning block 16 and the bottom of the lower positioning block 16 are both provided with positioning grooves adapted to the positioning bolts 15, the bottom end of the upper positioning bolt 15 penetrates the inner bottom wall of the upper limit frame 12 and extends to the interior of the positioning groove of the upper positioning block 16, and the top end of the lower positioning bolt 15 penetrates the inner top wall of the lower limit frame 12 and extends to the interior of the positioning groove of the lower positioning block 16. The top end of the upper threaded shaft 13 sequentially penetrates the inner top wall of the upper mounting cavity 11 and the upper surface of the connecting frame 1 and is fixedly connected with a twist cap, and the bottom end of the lower threaded shaft 13 sequentially penetrates the inner bottom wall of the lower mounting cavity 11 and the bottom of the connecting frame 1 and is also fixedly connected with a twist cap.

[0034] The working principle of the above embodiment is:

[0035] When in use, firstly, the screen frame 2 with the filter screen 3 installed needs to be connected to the connecting frame 1, and the positioning block 16 of the screen frame 2 is inserted into the inner side of the installation cavity 11 through the socket of the connecting frame 1, and then the twist cap is turned to drive the threaded shaft 13 to rotate. During the rotation of the threaded shaft 13, a thread thrust is generated on the inner side of the thread groove of the thread block 14. Through the thread thrust, the thread block 14 moves on the outer side of the threaded shaft 13. During the movement, the thread block 14 drives the positioning bolt 15 to move. During the movement, the positioning bolt 15 approaches the direction of the positioning block 16 until it is inserted into the inner side of the positioning groove of the positioning block 16.

[0036] In terms of supporting the filter screen 3, two brackets 4 fixedly connected to the right side of the mesh frame 2 provide a solid supporting foundation for the filter screen 3. The two brackets 4 are respectively located at the top and bottom of the mesh frame 2, ensuring the stability of the filter screen 3 in the vertical direction. The elastic telescopic rod 5 is connected to the activated carbon board 8 through the connecting plate 6 and the connecting rod 7 to form a stable supporting system. When the filter screen 3 is affected by external impact or internal airflow, since the activated carbon board 8 is in close contact with the filter screen 3, these external impacts or airflow will also act on the activated carbon board 8, and the activated carbon board 8 will act on the elastic telescopic rod 5 through the connecting plate 6 and the connecting rod 7. The telescopic rod 5 can absorb these forces and reduce the deformation and displacement of the filter 3. In addition, the design of the slide groove and the slide rod 9 on the inner side of the connecting plate 6 allows the connecting plate 6 to slide stably within a certain range, thereby adapting to the deformation of the filter 3. In addition, the two connecting rods 7 are connected by a connecting strip 10 to enhance the stability and integrity of the entire supporting structure. In addition, the activated carbon board 8, as a key part of the supporting structure, not only has a supporting function, but also can improve the filtering effect of the filter 3. The porous structure and adsorption performance of the activated carbon board 8 can adsorb and remove pollutants such as odors and harmful gases in the air, thereby further improving the cleanliness of the air.
