[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1:

[0027] like Figure 1-6As shown, the present embodiment provides a split assembled filter structure, including a first split filter 1, wherein a plurality of positioning rods 12 are fixedly connected on the left and right sides of the first split filter 1, a second split filter 11 is tightly fitted on the left and right ends of the first split filter 1, a plurality of positioning holes 13 are provided on the ends of the two second split filters 11 close to each other, the outer surfaces of the plurality of positioning rods 12 are plugged into the inner walls of the positioning holes 13 on the same side, two cables 14 are arranged inside the second split filter 11 on the left side, a sealing assembly 2 is arranged on the left side of the second split filter 11 on the left side, and a connecting assembly 3 is arranged inside the first split filter 1.

[0028] Specifically, in order to achieve the purpose of sealing the connection hole of the device connecting the cable, refer to Figure 3 and Figure 4 In this embodiment, the sealing assembly 2 includes two connecting tubes 21, the right ends of the two connecting tubes 21 are fixedly connected to the left end of the second split filter 11 located on the left side, and the two connecting tubes 21 are symmetrically arranged around the center of the second split filter 11 located on the left side.

[0029] For further information, see Figure 3 In this embodiment, the outer surface of the connecting tube 21 is provided with a thread, and the outer surface of the connecting tube 21 is threadedly connected to a rotating block 22, and the inner wall of the connecting tube 21 is fixedly connected to a circular block 23, and the inner wall of the circular block 23 is rotatably connected to four sealing plates 231, and the four sealing plates 231 are arranged in a circular array with the center of the connecting tube 21.

[0030] When the device completes the connection to the cable 14, the rotating block 22 is rotated clockwise to move it to the left. After the rotating block 22 moves a certain distance, since the left side of the rotating block 22 is set as an inclined surface, when the rotating block 22 contacts the limit plate 234 during the movement, the rotating block 22 will push the limit plate 234 to move downward. During the downward movement of the limit plate 234, the fixing rod 232 will drive the sliding of the inner wall of the rotating frame 24. When the fixing rod 232 slides, the rotating frame 24 will rotate with the movement of the fixing rod 232. When the fixing rod 232 slides downward, it will push the sealing plate 231 to rotate so that it is close to the surface of the cable 14.

[0031] See also Figure 4 In this embodiment, one end of the sealing plate 231 close to the center of the connecting tube 21 is tightly fitted with the surface of the cable 14, and one end of the sealing plate 231 away from the center of the connecting tube 21 is fixedly connected to a fixing rod 232. Four recessed holes are opened on the left inner wall of the connecting tube 21, and the inner walls of the four recessed holes are rotatably connected to the rotating frame 24. The outer surface of the fixing rod 232 is slidably connected to the inner wall of the rotating frame 24 on the same side.

[0032] At the same time, the outer surface of the fixing rod 232 is fixedly connected to the limiting block 233, the top of the fixing rod 232 is fixedly connected to the limiting plate 234, the end of the limiting plate 234 away from the center of the connecting tube 21 contacts the left inner wall of the rotating block 22, and a spring 235 is sleeved on the outer surface of the fixing rod 232, the end of the spring 235 away from the center of the connecting tube 21 is fixedly connected to the end of the rotating frame 24 on the same side away from the center of the connecting tube 21, and the end of the spring 235 away from the center of the connecting tube 21 is fixedly connected to the end of the limiting block 233 on the same side close to the center of the connecting tube 21.

[0033] During the implementation process, the connecting holes inside the connecting tube 21 can be sealed by four sealing plates 231, which can not only prevent tiny particles such as dust and fluff from entering the filter, ensuring the stability and reliability of its performance, but also significantly reduce the impact of external electromagnetic interference on the filter, ensuring that the filter can accurately filter the signal, thereby ensuring the normal operation of the electronic equipment.

[0034] Embodiment 2:

[0035] This embodiment sets a connection component based on the first embodiment.

[0036] Specifically, in order to achieve the purpose of being able to quickly assemble the device, refer to Figure 5 and Figure 6 In this embodiment, the connecting assembly 3 includes a bidirectional threaded rod 31, the front and back outer surfaces of the bidirectional threaded rod 31 are rotatably connected to the inner wall of the first split filter 1, and the front of the bidirectional threaded rod 31 is fixedly connected to a rotating block 2 32.

[0037] In this embodiment, the tops of the inner walls of the two second split filters 11 are fixedly connected with fixing plates 34 , and the front and back sides of the two fixing plates 34 are provided with card slots.

[0038] At the same time, the outer surface of the bidirectional threaded rod 31 is threadedly connected to two limit frames 33, and the tops of the two limit frames 33 are fixedly connected to connecting blocks 331. A slide groove is provided on the top of the inner wall of the first split filter 1, and the outer surfaces of the tops of the two connecting blocks 331 are slidably connected to the inner walls of the slide grooves. The left and right outer surfaces of the ends of the two limit frames 33 that are close to each other are plugged into the inner walls of the card slots on the same side.

[0039] During the implementation process, when the filter needs to be assembled, first, the several positioning holes 13 opened in the two second split filters 11 are plugged into the positioning rods 12 connected to the first split filter 1 so that they can be preliminarily assembled. When the two second split filters 11 are assembled, the rotating block 2 32 is rotated clockwise to drive the bidirectional threaded rod 31 to rotate on the inner wall of the first split filter 1. When the bidirectional threaded rod 31 rotates, it will drive the two limit frames 33 to move closer to each other. When the limit frames 33 move a certain distance, the protrusions on both sides of the limit frames 33 will be respectively inserted into the slots opened in the two fixing plates 34, so that the two second split filters 11 can be fixed on both sides of the first split filter 1. Not only can the filters be assembled quickly and the assembly efficiency of the staff is improved, but also by setting the connecting component 3 inside the device, it can avoid the rusting of its parts due to external influences.

[0040] The working principle of the present invention is as follows: when the device completes the connection of the cable 14, the rotating block 22 is rotated clockwise to move it to the left. After the rotating block 22 moves a certain distance, since the left side of the rotating block 22 is set as an inclined surface, when the rotating block 22 contacts the limit plate 234 during the movement, the rotating block 22 will push the limit plate 234 to move downward. During the downward movement of the limit plate 234, the fixing rod 232 will drive the sliding of the inner wall of the rotating frame 24. While the fixing rod 232 slides, the rotating frame 24 will rotate with the movement of the fixing rod 232. When the fixing rod 232 slides downward, it will push the sealing plate 231 to rotate so that it is tightly attached to the surface of the cable 14. The four sealing plates 231 can seal the connecting hole inside the connecting tube 21, which can not only prevent dust, fluff and other tiny particles from entering the filter, ensuring the stability and reliability of its performance, but also significantly reduce the influence of external electromagnetic interference on the filter, ensuring that the filter can accurately The signal is filtered to ensure the normal operation of the electronic equipment. When the filter needs to be assembled, the several positioning holes 13 opened in the two second split filters 11 are first plugged into the positioning rods 12 connected to the first split filter 1 so that they can be preliminarily assembled. When the two second split filters 11 are assembled, the rotating block 2 32 is rotated clockwise to drive the bidirectional threaded rod 31 to rotate on the inner wall of the first split filter 1. When the bidirectional threaded rod 31 rotates, the two limit frames 33 are driven to move closer to each other. When the limit frames 33 move a certain distance, the protrusions on both sides of the limit frames 33 are respectively inserted into the slots opened in the two fixing plates 34, so that the two second split filters 11 can be fixed on both sides of the first split filter 1. Not only can the filters be assembled quickly and the assembly efficiency of the staff is improved, but also by arranging the connecting component 3 inside the device, it can avoid the rusting of its parts due to external influences.
