[0033] Reference Figure 4-Figure 5 A filter 16 is fixedly connected to the adjacent side of the two side blocks 17. The filter 16 here is used to filter impurities in the air to prevent them from entering the interior of the cabinet 1 to affect the electrical equipment. The left side of the filter 16 is in contact with the top right side of the cabinet 1. A groove 18 is opened inside the side block 17. A button 19 is slidably connected to the inner wall of the groove 18. The groove 18 here provides a stable sliding space for the button 19. The outside of the button 19 is fixedly connected to a limit block 20, and the outside of the limit block 20 is slidably connected to the inner wall of the groove 18.

[0034] Reference Figure 5The limit block 20 here is used to limit the sliding range of the button 19. The outer sleeve of the button 19 is provided with a spring 21. The inner wall of the top right side of the cabinet 1 is slidably connected with two blocks 22. The cabinet 1 here provides stable support and sliding space for the two blocks 22. The front right side of the block 22 contacts the left side of the button 19. One end of the spring 21 is fixedly connected to one side of the limit block 20, and the other end of the spring 21 is fixedly connected to one side of the groove 18. The limit block 20 and the groove 18 here provide stable support for the spring 21 to ensure its stability during extension and retraction.

[0035] Reference Figure 5 The left front end of the card block 22 is movably connected with two ball bearings 23. The ball bearings 23 here are used to reduce the friction between the card block 22 and the cabinet 1 when the card block 22 slides inward when the button 19 is pressed to apply pressure to the card block 22. Two springs 3 24 are arranged on the inner wall of the right top end of the cabinet 1. One end of the spring 3 24 is fixedly connected to one side of the card block 22, and the other end of the spring 3 24 is fixedly connected to one side of the inner wall of the right top end of the cabinet 1. The card block 22 and the cabinet 1 here provide stable support for the spring 3 24. The card block 22 and the side block 17 are in a snap-fitting relationship. When the card block 22 and the side block 17 are disengaged, the filter 16 can be taken out to complete the cleaning work.

[0036] Working principle: When the staff needs to inspect the equipment inside the switch cabinet, they can first open the safety lock of the drawer 4 by turning the operating handle 5, and then pull the handle at the bottom of the front end to pull it out. After the drawer 4 is pulled out to the farthest distance, the side bars 7 at the bottom of the left and right sides will pop it out under the interaction of the spring 12 and the outer column 9. Here, the spring 12 is in a compressed state, and the limit plate 11 here plays a limiting role to prevent the inner column 10 from escaping from the range of motion of the outer column 9.

[0037] The position of the drawer 4 after the side bar 7 is popped out is further stabilized, and here one side of the outer column 9 and one side of the inner column 10 are movably connected with a ball 8 to adapt to the slight deviation of the outer column 9 and the inner column 10 caused by the side bar 7 when it is popped out, so that it can be more adaptable to the mutual force. After the side bar 7 is popped out, the staff will insert it into the slot 13, and then start to inspect the equipment inside it. After the inspection is completed, the side bars 7 on both sides can be pressed, and then the drawer 4 can be pushed back into the cabinet 1.

[0038] Then turn the operating handle 5 again, and check the indicator light 2 and the instrument 3 to see whether they are successfully engaged with the safety lock to prevent accidents.

[0039] After long-term use, a lot of dust will adhere to the surface of the filter 16 outside the switch cabinet fan 15. At this time, it needs to be cleaned to ensure the normal operation of the heat dissipation function. At this time, the two buttons 19 can be pressed. The buttons 19 here will transfer the pressure to the block 22 after being squeezed. Because of the presence of the spring three 24, the block 22 will move inward. The two ball bearings 23 here ensure the smoothness and smoothness of the sliding of the block 22, making it easier to press.

[0040] When the right side of the card block 22 is disengaged from the engagement with the side block 17, the side block 17 together with the filter 16 can be taken out and the dust on it can be cleaned. The spring 21 inside the groove 18 is used to cooperate with the limit block 20 to complete the reset operation. After cleaning, the above steps can be reversed to reinstall the filter 16.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
