A control cabinet body is located on one side of the interior of the housing. Two sliding blocks are fixedly connected to both sides of the control cabinet body. A circular hole is formed on one side of each sliding block. The advantages of this invention are: by starting the four motors, the four threaded shafts rotate, causing the control cabinet body to move out of the housing, making it easier for maintenance personnel to inspect the electronic components inside the control cabinet body. LED lights illuminate the control cabinet body to facilitate maintenance.

[0004] However, in the above technical solution, only four motors are used to drive the threaded rod to rotate. The main body of the control cabinet is moved directly out of the control shell to facilitate maintenance work by the staff. However, the electrical equipment and the main body of the control cabinet itself have a certain weight. Although the high and low voltage control cabinets are fixed on the ground, the movement of the electrical equipment will cause the control cabinet to bear greater pressure, which will reduce its service life and increase the risk of damage.

[0023] Example 1

[0024] like Figures 1-5 As shown, the present invention proposes a high and low voltage control cabinet that is easy to maintain, including a control cabinet body 1, a heat dissipation window 2 and an unfolding assembly. The heat dissipation window 2 is provided on the side wall of the control cabinet body 1, and the unfolding assembly is connected to the control cabinet body 1. When the unfolding assembly is in use, the moving end of the unfolding assembly gradually rotates, and the moving end unfolds the control cabinet body 1 and pushes the terminal block with power distribution equipment and lines away from the control cabinet body 1.

[0025] In an optional embodiment, the control cabinet body 1 comprises a base 3, a fixed plate 4, a top plate 5, a movable plate 6, and a cabinet door 7.

[0026] In an optional embodiment, a lighting lamp 8 and a photoresistor 9 are connected to the top plate 5, and the photoresistor 9 is electrically connected to the lighting lamp 8.

[0027] Example 2

[0028] like Figures 2-5 As shown, this utility model proposes a high and low voltage control cabinet that is easy to maintain. Compared with Embodiment 1, this embodiment describes the detailed structure of the unfolding assembly. The unfolding assembly includes a rotating shaft 10, an adjusting handwheel 11, a rotating plate 12, a connecting rod 13, a fixing block 14, a sliding assembly, and an auxiliary assembly. The rotating shaft 10 is rotatably connected to the top plate 5 by a bearing. The adjusting handwheel 11 is connected to the rotating shaft 10. The rotating plate 12 is connected to the rotating shaft 10. Both ends of the rotating plate 12 are hinged to the connecting rod 13. Two fixing blocks 14 are arranged in parallel. The fixing blocks 14 are connected to the movable plate 6. One end of the connecting rod 13 is rotatably connected to the fixing block 14 by a convex rod bearing. The sliding assembly is connected to the base 3. When the sliding assembly is in use, the moving end of the sliding assembly moves synchronously with the movable plate 6, and the moving end drives the terminal block of the installed power distribution equipment away from the main body 1 of the control cabinet. The auxiliary assembly is connected to the cabinet. When the auxiliary assembly is in use, the auxiliary assembly changes the position of the operator when adjusting the rotating shaft 10.

[0029] The sliding assembly includes a push block 15, a sliding rod 16, a fixed base 17, a sliding seat 18, and an elastic element 19. Two push blocks 15 are symmetrically arranged and connected to the movable plate 6. Two sliding rods 16 are arranged in parallel, and each end of the sliding rod 16 is connected to a fixed base 17, which is connected to the base 3. The sliding seat 18 is slidably connected to the sliding rod 16 and is connected to the wiring plate. The number of elastic elements 19 corresponds to the number of sliding rods 16, and the elastic elements 19 are sleeved on the outside of the sliding rods 16. The elastic elements 19 may be selected from, but are not limited to, springs.

[0030] The auxiliary components include a driven gear 20, a mounting base 21, an adjusting shaft 22, an adjusting handle 23, a driving gear 24, and a limiting member 25. The driven gear 20 is connected to the rotating shaft 10. There are two mounting bases 21 arranged in parallel, and the adjusting shaft 22 is rotatably connected to the mounting base 21.

[0031] In an optional embodiment, the adjusting shaft 22 consists of a rotating cylinder 26 and a moving rod 27. The inner wall of the rotating cylinder 26 is provided with a plurality of grooves 28, and the moving rod 27 is connected with a plurality of protrusions 29 that are slidably connected to the grooves 28.

[0032] One end of the adjusting shaft 22 is connected to the adjusting handle 23, and the driving gear 24 is connected to the adjusting shaft 22. The driving gear 24 meshes with the driven gear 20 for transmission. Both the driving gear 24 and the driven gear 20 are bevel gears or bevel gears.

[0033] The limiting component 25 is connected to the adjusting shaft 22;

[0034] In an optional embodiment, the limiting member 25 consists of a fixed plate 30 and limiting rods 31. The fixed plate 30 is connected to the moving rod 27, and multiple limiting rods 31 are connected to the fixed plate 30. The mounting base 21 has through holes that cooperate with the limiting rods 31.

[0035] In summary, when using this utility model, during maintenance, the operator first opens the lock on the cabinet door 7, and then rotates the adjusting handwheel 11 or the adjusting handle 23. Due to individual height and habits, adjustments are made in two different ways. Directly rotating the adjusting handwheel 11 will cause the rotating shaft 10 and the rotating plate 12 to rotate. The connecting rod 13 on the rotating plate 12 drives the fixed blocks 14 on the two movable plates 6 to rotate around their hinge point with the fixed plate 4. Simultaneously, the rotation of both will push the sliding seat 18 with protrusions along the sliding rod 16 horizontally via the pushing block 15, causing the terminal block on the sliding seat 18, used for connecting electrical components and lines, to move a distance away from the control cabinet body 1 to prevent the control cabinet body 1 from obstructing the view. At the same time, during control... After the cabinet body 1 is opened, the photoresistor 9 detects the change in light and controls the lighting lamp 8 to turn on to provide lighting conditions. When the adjustment handle 23 is rotated, the adjustment handle 23 will drive the adjustment shaft 22 and the drive gear 24 to rotate. The drive gear 24 meshes with the driven gear 20 on the rotating shaft 10 to drive the rotating plate 12 to rotate and adjust the position of the fixed plate 4. After the adjustment is completed, the adjustment handle 23 can be moved along the central axis of the adjustment shaft 22 to make the moving rod 27 slide in the rotating cylinder 26, so that the fixed plate 30 on the moving rod 27 moves and inserts the limiting rod 31 into the through hole opened on the mounting base 21, thereby fixing the position of the adjustment shaft 22, the fixed plate 4, the rotating shaft 10 and the sliding seat 18, and preventing them from being disturbed by external forces. The rotation of the movable plate 6 will not disturb the workers in the maintenance state.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
