The surface of the inner edge 9 is provided with a slide groove corresponding to the pull rod 10, and a side opening is provided on one side of the top of the slide groove. Push the pull rod 10 to move upward inside the slide groove of the inner edge 9, and the pull rod 10 also moves upward inside the vertical groove of the cabinet door 2. The upward pull rod 10 makes the baffle move upward inside the cabinet body 1 until the baffle corresponds to the side opening. Pull the pull rod 10 forward, and the baffle fits the rear side of the cabinet door 2 through the side opening. At this time, pull the cabinet door 2 to open. Multiple filter plates 6 are correspondingly plugged into the inner frame 5.

After the two convex plates 12 of the inner frame 5 correspond to the two vertical rods 13, the inner frame 5 is vertically placed between the two side frames 11. At this time, the convex plates 12 are correspondingly sleeved on the surfaces of the vertical rods 13. The downwardly moved convex plates 12 cooperate to squeeze the first springs 17 on the surfaces of the vertical rods 13 until the bottom surface of the convex plates 12 fits with the top surface of the side frames 11. The two nuts 16 on the surface of the cross bar 15 are screwed.

The moving slider 22 drives the filter plate 6 to move synchronously through the plug-in components. The gear 20 is rotated, and the rotating gear 20 uses the rack 21 to make the gear 20 on the adjacent side rotate synchronously. The rotating gear 20 makes the rotating rod 19 rotate inside the inner groove 18. The spiral cooperation between the rotating rotating rod 19 and the slider 22 makes the slider 22 move inside the inner groove 18 until the slider 22 corresponds to the plug-in component of the filter plate 6, pushing the filter plate 6 to move downward. The downwardly moved filter plate 6 is plugged into the surface of the slider 22 by the plug-in component. The moving slider 22 drives the filter plate 6 to move inside the inner frame 5 by the plug-in component until the outer side surface of the filter plate 6 fits with the outer side wall inside the inner frame 5. At this time, the filter plate 6 corresponds to the heat dissipation port 4 through the second opening 8.

[0034] The remaining filter plates 6 are installed in sequence inside the inner frame 5 through plug-in components, and the positions of the filter plates 6 are adjusted through the spiral cooperation of the rotating rod 19 and the slider 22, so that multiple filter plates 6 are arranged in parallel and fit inside the inner frame 5, which facilitates the cooperation of multiple filter plates 6 to filter external dust and prevents external dust from entering the cabinet 1 through the heat dissipation port 4.

The two sides of the filter plate 6 are embedded with inner rods 25, the plug-in bracket 23 is vertically sleeved on the surface of the inner rod 25, and the surface of the inner rod 25 is sleeved with a second spring 26, the top end of the second spring 26 is connected to the bottom surface of the plug-in bracket 23, and the bottom end of the second spring 26 is connected to the bottom end of the inner rod 25, and the second spring 26 is in a stretched state. After the filter plate 6 has been used for a period of time, the gear 20 is rotated in the opposite direction, and the gear 20 causes the rotating rod 19 to rotate in the opposite direction. The rotating rod 19 that rotates in the opposite direction causes the slider 22 to move inward. The slider 22 uses the plug-in component to move the filter plate 6 inward, and the filter plate 6 gradually moves away from the inner wall of the cabinet 1, pulling the outermost filter plate 6 upward, and the second spring 26 gradually contracts. The elastic force of the second spring 26 makes the rack 23 always cooperate with the slider 22, and the filter plate 6 continues to be pulled upward. The upwardly moved filter plate 6 is separated from the rack 23 and the slider 22 by the elastic force of the second spring 26, and the new filter plate 6 is reinserted into the inner frame 5, and the new filter plate 6 is conveniently confined inside the inner frame 5 by the spiral cooperation of the rotating rotating rod 19 and the slider 22.

[0036] By rotating the rotating rod 19 and the slider 22, the rack 23 can drive the filter plate 6 to move inside the inner frame 5, so that filter plates 6 of different thicknesses can be installed inside the inner frame 5. At the same time, different numbers of filter plates 6 can also be installed inside the inner frame 5, thereby improving the adaptability of the inner frame 5 to different filter plates 6 and ensuring quick replacement of the filter plates 6.

The two nuts 16 on the surface of the crossbar 15 are screwed. Since the two nuts 16 cooperate with the side frames 11 to limit the crossbar 15, the rotating nuts 16 make the crossbar 15 use the bottom block 14 to drive the inner frame 5 to move. The outer side surface of the moving inner frame 5 gradually fits with the inner wall of the cabinet 1.
