Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0024] Reference Figure 1-4 This is the first embodiment of the present invention, providing a GGD type AC low-voltage distribution cabinet, including a cabinet body 1. The cabinet body 1 has an internal cavity. An air inlet pipe 5 communicating with the cavity is located at the bottom of the outer wall of the cabinet body 1. The air inlet pipe 5 is positioned low, resulting in a lower air temperature, which facilitates heat dissipation. A first base 6 is fixedly connected to the inner wall of the air inlet pipe 5. An air intake fan 8 is fixedly installed on the outer wall of the first base 6. The negative pressure generated by the rotation of the air intake fan 8 draws external air into the cabinet body 1. A filter plate 7 is snapped into the inner wall of the air inlet pipe 5. To prevent dust from entering the interior of cabinet 1, a support 21 is provided above the filter plate 7. A push rod 20 is slidably connected to the inner wall of the support 21. The push rod 20 is used to move the rectangular block 15 and the circular block 16. An air outlet pipe 9 communicating with the cavity is opened at the top of the outer wall of cabinet 1. The air outlet pipe 9 is located at a high position and the air temperature is high. A second base 10 is fixedly connected to the inner wall of the air outlet pipe 9. An air outlet fan 11 is fixedly installed on the outer wall of the second base 10. The air outlet fan 11 is used to exhaust the hot air inside cabinet 1 from the air outlet pipe 9.

[0025] The inner wall of the air inlet duct 5 is provided with an installation groove to facilitate the sliding of the filter plate 7. The outer wall of the filter plate 7 is fixedly connected to an installation block 12 that is fixedly connected to the bottom of the bracket 21. The installation block 12 is used to drive the filter plate 7 to move. The inner wall of the installation groove is provided with a limiting groove that penetrates the outer wall of the installation block 12. The inner wall of the limiting groove is slidably connected to two mirror-distributed limiting posts 13. The limiting posts 13 are used to engage the installation block 12. A first spring 14 is connected between the outer wall of the limiting post 13 and the inner wall of the limiting groove. The first spring 14 is used to push the limiting post 13.

[0026] A rectangular block 15 is slidably connected to the outer and inner walls of the push rod 20. The outer wall of the rectangular block 15 is provided with a slider. The outer wall of the mounting block 12 is provided with a moving groove to facilitate the sliding of the rectangular block 15. A connecting post 24 is fixedly connected to the bottom end of the push rod 20. The connecting post 24 is used to drive the arc block 23 to rotate. The arc block 23 is fixedly connected to the bottom end of the connecting post 24. The arc block 23 is used to drive the limit rod 17 to move. A circular block 16 is fixedly connected to the bottom end of the arc block 23.

[0027] The inner wall of the rectangular block 15 has a circular groove for installing the circular block 16. The inner wall of the circular groove has two rectangular holes that are mirror-distributed. The inner wall of the rectangular holes is slidably connected to a limit rod 17. The limit rod 17 is used to push the limit post 13. The top of the limit rod 17 is fixedly connected to a rectangular plate 18. A second spring 19 is connected between the outer wall of the rectangular plate 18 and the inner wall of the circular groove. The second spring 19 is used to drive the rectangular plate 18 to move.

[0028] During use, after prolonged use, it needs to be disassembled. Pushing the disc 22 moves the push rod 20, which in turn moves the rectangular block 15. The rectangular block 15 moves to the bottom along the moving groove. Rotating the disc 22, via the push rod 20, rotates the connecting column 24, which in turn rotates the arc-shaped block 23. The arc surface of the arc-shaped block 23 pushes the limiting rod 17 to move along the inner wall of the rectangular hole. The limiting rod 17 moves the rectangular plate 18, compressing the second spring 19. The limiting rod 17 compresses the limiting column 13, and the limiting column... 13. The first spring 14 is squeezed to disengage from the mounting block 12. Then, the mounting block 12 is moved by pulling the bracket 21. The mounting block 12 moves the filter plate 7 away from the air inlet pipe 5. After cleaning, the filter plate 7 is aligned with the mounting groove and placed in. The mounting block 12 squeezes the limiting post 13 to move along the limiting groove. After placement, the rotating disc 22 drives the arc block 23 to rotate. The second spring 19 drives the limiting rod 17 to reset through the rectangular plate 18. The first spring 14 is released and pushes the limiting post 13 to engage with the mounting block 12. Example

[0029] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a disc 22 is fixedly connected to the top of the push rod 20; a movable groove is provided on the inner wall of the air outlet pipe 9; a plurality of fixed columns 26 arranged in a circular array are fixedly connected between the inner walls of the movable groove; a baffle 25 is slidably connected to the outer wall of the fixed column 26; the baffle 25 is used to prevent foreign objects from entering the cabinet 1 when not in use; a push plate 29 is fixedly connected to the outer wall of the baffle 25; the push plate 29 is used to drive the baffle 25 to rotate around the cross-section of the fixed column 26; and a slot is provided on the inner wall of the movable groove.

[0030] A locking block 27 is slidably connected to the inner wall of the slot. The locking block 27 is used to engage the position of the baffle 25. A third spring 28 is connected between the outer wall of the locking block 27 and the bottom of the slot. The third spring 28 is used to drive the locking block 27 to move. The outer wall of the baffle 25 has a slot with the same opening as the slot. Two cabinet doors 2 are slidably connected to the inner wall of the cavity. A handle 3 is fixedly connected to the outer wall of the cabinet door 2. Four casters 4 are fixedly connected to the bottom of the cabinet body 1 in a rectangular array.

[0031] During use, when needed, rotate the push plate 29. The push plate 29 drives the baffle 25 to rotate around the cross-section of the fixed column 26. The baffle 25 presses against the locking block 27. The locking block 27 is forced to press against the third spring 28. When the slot passes the locking block 27, the third spring 28 is released and pushes the locking block 27 into the slot, thus fixing the position of the baffle 25. When no longer needed, rotate the push plate 29 to drive the baffle 25 to rotate. Since the outer wall of the locking block 27 is rounded, the locking block 27 retracts under force, and the baffle 25 resets under the influence of gravity. The operation is then complete.

[0032] The remaining structure is the same as that in Example 1.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
