[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] according to Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this embodiment proposes a power distribution switch control cabinet, including a cabinet 1. The cabinet 1 is provided with an exhaust window 2 and a ventilation window 3 on the outside. The ventilation window 3 is fixedly connected to the side of the cabinet 1.

[0027] A filter frame 4 is provided on the side of the ventilation window 3 away from the cabinet 1. The upper end of the filter frame 4 is engaged with the ventilation window 3 through a snap-fit ​​structure. A connecting plate 7 is provided at the lower end of the filter frame 4. The connecting plate 7 is rotatably connected to the lower end of the ventilation window 3 through a hinge 8. A filter 5 is provided on the inner side of the filter frame 4.

[0028] The fan is located inside the exhaust window 2. When the fan starts, a negative pressure is formed inside the cabinet 1. External air enters the cabinet 1 through the ventilation window 3 and is then discharged from the exhaust window 2 at the bottom of the cabinet 1. When the airflow passes through the filter frame 4, the dust carried in the airflow is blocked by the filter screen 5 inside the filter frame 4, while the airflow passes normally.

[0029] A movable shaft 15 is provided on the side of the connecting plate 7 facing the filter frame 4. The movable shaft 15 is rotatably connected to the filter frame 4. A spring reset assembly for pulling the movable shaft 15 into the connecting plate 7 is provided inside the connecting plate 7. A pin positioning assembly for limiting the rotation of the filter frame 4 is provided on the facing sides of the connecting plate 7 and the filter frame 4.

[0030] The lower end of the filter frame 4 is hinged to the lower end of the ventilation window 3 via the connecting plate 7 and the hinge 8. During normal use, the filter frame 4 is fixed to the outside of the ventilation window 3 by a snap-fit ​​mechanism. When the filter screen 5 needs to be cleaned, pull the filter frame 4 to release the snap-fit ​​between the filter frame 4 and the ventilation window 3, and flip the filter frame 4 down from one side of the ventilation window 3. During the cleaning process, the filter screen 5 can also be pulled outward to pull out the movable shaft 15 and release the locking of the pin positioning component on the filter frame 4, so that the filter screen 5 can be flipped over. The filter screen 5 is easy to clean and maintain.

[0031] It is worth explaining in detail that one end of the movable shaft 15 is rotatably connected to the filter frame 4, and the other end of the movable shaft 15 away from the filter frame 4 is inserted into the connecting plate 7, and the movable shaft 15 is slidably connected to the connecting plate 7.

[0032] Specifically, the pin positioning assembly includes at least two limiting pins 13. The limiting pins 13 are fixedly connected to the side of the filter frame 4 facing the connecting plate 7. The side of the connecting plate 7 facing the filter frame 4 has a pin groove 14, and the pin groove 14 is plugged into and pulled into the limiting pin 13.

[0033] After pulling the filter frame 4 outward, the movable shaft 15 slides outward along the inner wall of the connecting plate 7, increasing the distance between the filter frame 4 and the connecting plate 7. At this point, the filter frame 4 can be rotated to flip the filter 5, making it easier to clean. After cleaning, the limiting pin 13 on the filter frame 4 is engaged in the corresponding pin groove 14. The pin groove 14, in cooperation with the limiting pin 13, continues to restrict the rotation of the filter frame 4.

[0034] Regarding the spring return assembly:

[0035] The spring reset assembly includes a spring groove 18, which is formed inside the connecting plate 7. A spring 16 and a baffle 17 are provided in the spring groove 18. The baffle 17 is slidably connected to the spring groove 18 and is fixedly connected to the end of the movable shaft 15 away from the filter frame 4. The spring 16 is sleeved on the outside of the movable shaft 15 and is fixedly connected between the baffle 17 and the inner wall of the spring groove 18.

[0036] After the filter screen frame 4 is pulled outward, the baffle 17 slides along the spring groove 18, and the spring 16 in the spring groove 18 contracts. After the filter screen frame 4 is released, under the action of the spring 16, the baffle 17 will drive the movable shaft 15 to return to its original position, so that the filter screen frame 4 and the connecting plate 7 are in a tight fit.

[0037] To facilitate the opening of the filter frame 4, the filter frame 4 is fixed to the ventilation window 3 using a snap-fit ​​connection. Specifically, the snap-fit ​​structure includes multiple snaps 11 located at the upper end of the filter frame 4. The snaps 11 are fixedly connected to the side of the filter frame 4 facing the ventilation window 3, and the snaps 11 engage with the slots 12 located on the outside of the ventilation window 3. After rotating the filter frame 4 and placing it on the ventilation window 3, the snaps 11 at the upper end of the filter frame 4 will engage with the slots 12 at the upper end of the ventilation window 3. The slots 12, through their cooperation with the snaps 11, limit the movement of the filter frame 4 without affecting its opening.

[0038] To facilitate the pulling and flipping of the filter frame 4, in a preferred embodiment, a pull ring 6 is provided on each of the left and right sides of the filter frame 4, and the pull ring 6 is fixedly connected to the filter frame 4. When rotating or pulling the filter frame 4, simply engage the pull ring 6.

[0039] To prevent the filter frame 4 from falling directly to the ground when opened, a check plate 10 is provided on the outside of the cabinet 1 to restrict the continued rotation of the connecting plate 7. The check plate 10 is located below the hinge 8, and multiple fixing bolts 9 are fitted at the lower end of the check plate 10. The fixing bolts 9 are threaded into bolt holes on the outside of the cabinet 1. To remove the check plate 10 from the outside of the cabinet 1, simply unscrew the fixing bolts 9 at the lower end of the check plate 10 from the bolt holes on the outside of the cabinet 1.

[0040] How this application works:

[0041] The fan is located inside the exhaust window 2. When the fan starts, a negative pressure is created inside the cabinet 1. External air enters the cabinet 1 through the ventilation window 3 and then exits through the exhaust window 2 at the bottom of the cabinet 1. When the airflow passes through the filter frame 4, the dust carried in the airflow is blocked by the filter screen 5 inside the filter frame 4, while the airflow passes normally. The lower end of the filter frame 4 is hinged to the lower end of the ventilation window 3 via the connecting plate 7 and the hinge 8. During normal use, the filter frame 4 is fixed to the outside of the ventilation window 3 by a snap-fit ​​mechanism. When the filter screen 5 needs to be cleaned, pull the filter frame 4 to release the snap-fit ​​between the filter frame 4 and the ventilation window 3, and flip the filter frame 4 down from one side of the ventilation window 3. During the cleaning process, the filter screen 5 can also be pulled outwards to pull out the movable shaft 15 and release the locking of the pin positioning component on the filter frame 4, allowing the filter screen 5 to be flipped over. The filter screen 5 is easy to clean and maintain.
