DETAILED DESCRIPTION

[0023] The following description will be made in conjunction with the accompanying drawings Figure 1 - the accompanying drawings Figure 3 The application will be further described in detail.

[0024] A power distribution cabinet convenient to maintain, referring to Figure 1 and Figure 2 , comprising a cabinet body 1, a cabinet door 2 and a mounting frame 3, the cabinet body 1 is hollow and has an opening on one side, the cabinet door 2 is rotationally connected to the cabinet body 1 and is used to close the opening of the cabinet door 2, and the mounting frame 3 is slidingly arranged in the cabinet body 1, and electrical equipment is mounted on the mounting frame 3. When the maintenance personnel need to maintain the electrical equipment, the mounting frame 3 is pulled out of the cabinet body 1, so that the electrical equipment is extended out of the cabinet body 1, at this time, since the mounting frame 3 is not blocked on both sides, the maintenance personnel can conveniently maintain the electrical equipment.

[0025] Specifically, the mounting frame 3 comprises a back plate 31, a top plate 32 and a mounting plate 33, the top plate 32 is fixedly connected to the top end of the back plate 31 and is slidingly connected in the cabinet body 1, the bottom plate 34 is fixedly connected to the bottom end of the back plate 31 and is slidingly connected in the cabinet body 1, the mounting plate 33 is provided with a plurality of mounting plates 33, and the plurality of mounting plates 33 are fixedly connected to the back plate 31. The top plate 32 and the back plate 31 are slidingly arranged on the cabinet body 1, so as to realize the sliding connection between the mounting frame 3 and the cabinet body 1, and the mounting plate 33 is used to mount various electrical equipment, and a plurality of mounting plates 33 are arranged to provide mounting positions for a plurality of electrical equipment. Moreover, since the mounting frame 3 is not blocked on both sides, the maintenance personnel can maintain the electrical equipment from both sides, and the maintenance is more convenient.

[0026] Further, there is a gap between the back plate 31 and the inner wall of the cabinet body 1, and various electrical equipment connection wires can be stored in the gap, when the mounting frame 3 moves out of the cabinet body 1, the position of the electrical equipment will also change, and some electrical equipment with connection wires can leave a moving allowance for the connection wires, and the connection wires are placed in the gap, when the mounting frame 3 slides, the connection wires gradually straighten, so as to avoid the situation that the connection wires are broken due to the movement of the mounting frame 3.

[0027] Further, the mounting plate 33 is detachably connected to the back plate 31. The height of each electrical equipment is different, and thus the required space is also different. By detachably connecting the mounting plate 33 to the back plate 31, before the electrical equipment is installed, the mounting position of the mounting plate 33 can be adjusted, so as to adapt to the installation space of the electrical equipment, and thus the space utilization is optimized.

[0028] Further, a through slot 331 is formed in each mounting plate 33, so as to form a handle 332 on the mounting plate 33. When the sliding mounting frame 3 is slid, the handle 332 can be held to slide, and thus the maintenance personnel can use conveniently.

[0029] Specifically, a plurality of mounting holes 311 are formed in the back plate 31, and a bolt 312 is arranged on the mounting plate 33. The mounting plate 33 is detachably connected to the back plate 31 by screwing the bolt 312 and the mounting hole 311. A plurality of mounting holes 311 are reserved in the back plate 31. When the position of the mounting plate 33 is adjusted, only the mounting bolt 312 needs to be disassembled, and thus the mounting and dismounting process is convenient. After the mounting plate 33 is installed, a plurality of mounting holes 311 without the mounting bolt 312 are reserved. These mounting holes 311 can discharge the heat generated by the electrical equipment into the gap between the back plate 31 and the inner wall of the cabinet 1, and the heat is discharged through the heat dissipation holes on the cabinet 1, so as to reduce the damage of the electrical equipment due to high temperature.

[0030] Further, the power distribution cabinet further comprises a limiting device 4. The limiting device 4 is used for limiting the sliding of the mounting frame 3, so as to reduce the position movement of the mounting frame 3 in the daily use of the power distribution cabinet.

[0031] Referring to Figure 2 and Figure 3 Specifically, the limiting device 4 comprises a limiting rod 41 and a limiting plate 42. The limiting rod 41 is fixedly connected to the cabinet 1 and is arranged along the sliding direction of the top plate 32 and / or the bottom plate 34. The back plate 31 is provided with a through hole 313. When the mounting frame 3 slides in the cabinet 1, the limiting rod 41 slides in the through hole 313. In the embodiment, two limiting rods 41 are arranged. In other embodiments, the number of the limiting rods 41 can be several. The through hole 313 is provided with a plurality of through holes 313. The plurality of through holes 313 are arranged in one-to-one correspondence with the plurality of limiting rods 41.

[0032] The limiting rod 41 is provided with a first limiting slot 411, which is located at one end of the limiting rod 41 close to the inner bottom wall of the cabinet 1. The limiting plate 42 is slidingly connected to the back plate 31 and can slide towards the direction close to or away from the perforated hole 313. When the top plate 32 and the bottom plate 34 slide into the cabinet 1, the limiting plate 42 is positionally corresponding to the first limiting slot 411, and the limiting plate 42 is inserted into the first limiting slot 411. At this time, the movement of the back plate 31 is limited through the mutual cooperation of the limiting plate 42 and the first limiting slot 411, so as to limit the sliding of the mounting rack 3. When it is needed to slide the mounting rack 3, the limiting plate 42 is slid upward to release the limiting of the back plate 31, and at this time, the mounting rack 3 can be continuously slid.

[0033] Further, the limiting plate 42 is provided with a slot 421. When the limiting plate 42 is inserted into the first limiting slot 411, the limiting rod 41 is inserted into the slot 421, so as to further increase the mutual connection between the limiting plate 42 and the limiting rod 41, and further increase the fixing effect on the mounting rack 3.

[0034] Further, the limiting rod 41 is provided with a second limiting slot 412, and the limiting plate 42 can be slid into the second limiting slot 412. The second limiting slot 412 is spaced apart from the first limiting slot 411 along the axis direction of the limiting rod 41. That is, when the mounting rack 3 is slid outward to a predetermined position, the limiting plate 42 is positionally corresponding to the second limiting slot 412, and at this time, the electrical equipment is located outside the cabinet 1. Then, the limiting plate 42 is slid and inserted into the second limiting slot 412 to limit the sliding of the mounting rack 3, so as to reduce the movement of the mounting rack 3 when the electrical equipment is maintained by the maintenance personnel, and facilitate the maintenance of the electrical equipment by the maintenance personnel.

[0035] Further, the limiting device 4 further comprises a fixing assembly 43. When the limiting plate 42 is inserted into the first limiting slot 411 or the second limiting slot 412, the fixing assembly 43 limits the position of the limiting plate 42, so as to reduce the situation that the limiting plate 42 is separated from the first limiting slot 411 or the second limiting slot 412 due to external factors.

[0036] Specifically, the fixing assembly 43 comprises a first magnet 431 and a second magnet 432, the first magnet 431 and the second magnet 432 are arranged staggeredly, the limiting plate 42 is made of a magnetic material and can be magnetically attracted to the first magnet 431 or the second magnet 432, when the limiting plate 42 is inserted into the first limiting slot 411 or the second limiting slot 412, the first magnet 431 is magnetically attracted to the limiting plate 42, and the second magnet 432 is arranged on the side of the first magnet 431 away from the through hole 313. That is, when the limiting plate 42 is separated from the first limiting slot 411 or the second limiting slot 412, the limiting plate 42 is magnetically attracted to the second magnet 432 at this time, thereby limiting the movement of the limiting plate 42 and reducing the friction between the limiting plate 42 and the limiting rod 41, so as to facilitate the sliding of the mounting frame 3.
