[0004] In the above patent, the purpose of expanding the internal capacity of the power cabinet is mainly achieved by pulling out the lateral expansion cabinet set in the hollow cabinet body. However, since there is a baffle on the side of the lateral expansion cabinet close to the cabinet door of the power cabinet, when the power cabinet does not need internal expansion, the baffles in front of the lateral expansion cabinets on both sides will directly block the cabinet door, which is inconvenient for the installation of electronic components inside the power cabinet, resulting in a significant reduction in the practicality of the power cabinet. Utility Model Content

[0005] In response to the above problems, the present invention provides a power distribution cabinet with adjustable internal expansion capacity. By adjusting the regulator in the adjustment device, the power cabinet with adjustable internal expansion capacity can be expanded in space during use without affecting the normal operation of the power cabinet, effectively avoiding the impact on the normal operation of the power cabinet caused by the need to greatly affect the normal operation of the power cabinet before internal expansion can be carried out.

[0006] To achieve the above-mentioned object, the present invention is implemented through the following technical solution: a power distribution cabinet with adjustable internal expansion, comprising an adjustment device, a plurality of side doors installed on the side of the adjustment device, a main door installed on the front end of the adjustment device, a plurality of adjusters installed in the adjustment device, a plurality of snap-fit ​​keys in the adjusters, an expansion cavity defined next to the snap-fit ​​keys, a plurality of slide keys installed next to the expansion cavity, a rotation slot defined next to the slide keys, a plurality of smooth plates fixedly connected next to the expansion cavity, the inner sides of the snap-fit ​​keys cooperating with the inner sides of the slide keys.

[0008] Furthermore, the cabinet includes an outer shell, a plurality of limit plates fixedly connected to the outer shell, and a plurality of upper rotating shafts fixedly connected to the outer shell. The outer side of the smooth plate engages with the inner side of the limit plates, and the outer side of the upper rotating shafts nests with the inner side of the rotating groove. The nesting of the outer side of the upper rotating shafts with the inner side of the rotating groove makes the internal structure of the power cabinet with adjustable internal capacity more solid and reliable, greatly improving the safety of the operation of the power cabinet with adjustable internal capacity.

[0009] Furthermore, a spring column is fixedly connected to the inside of the outer shell, with an insert key connected to the front end of the spring column. A swing shaft is nested at the upper end of the insert key, and the outer side of the swing shaft mates with the inner side of the spring column. This mates with the inner side of the spring column, ensuring more stable operation of the insert key and improving the practicality of the power cabinet with adjustable internal expansion capacity.

[0010] Furthermore, the upper end of the insertion key mates with the upper end of the smooth plate, the inner side of the expansion cavity mates with the inner side of the cabinet, and the outer side of the side shaft nests with the inner side of the side door. This nesting of the outer side shaft and the inner side door makes the internal structure of the power cabinet with internal expansion and adjustment more solid and reliable, greatly improving the operational stability of the power cabinet with internal expansion and adjustment.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model moves the locking key in the adjustment device in the expansion cavity and cooperates with the upper adjuster to rotate around the upper rotating shaft, so that the power cabinet with adjustable internal expansion can operate normally when the expansion is not needed. It effectively avoids that when the power cabinet does not need internal expansion, the baffles in front of the expansion cabinet on both sides will be directly blocked behind the cabinet door, which is inconvenient for the installation of electronic components inside the power cabinet and greatly reduces the practicality of the power cabinet.

A plurality of upper rotating shafts 141 are fixedly connected to the outer shell 142. The outer side of the smooth plate 111 cooperates with the inner side of the limit plate 143. The outer side of the upper rotating shaft 141 is nested with the inner side of the rotating groove 114. A spring column 121 is fixedly connected to the inner side of the outer shell 142. The front end of the spring column 121 is connected to the insert key 123. The upper end of the insert key 123 is nested with the swing shaft 122. The outer side of the swing shaft 122 cooperates with the inner side of the spring column 121, and the upper end of the insert key 123 cooperates with the upper end of the smooth plate 111. The inner side of the expansion cavity 115 cooperates with the inner side of the cabinet 14, and the outer side of the side rotating shaft 13 is nested with the inner side of the side door 2.

[0024] The height of the locking key 113 is consistent with that of the sliding key 112 , so that the sliding key 112 can be finally limited by the locking key 113 when moving.

[0025] The swing limit of the smooth plate 111 is exactly on the same straight line as the limiting plate 143 , so that the adjuster 11 can enter the limiting plate 143 through the smooth plate 111 and be fixed after swinging.

In order to observe the professional and technical features more intuitively in the figure, the bolt connection is appropriately hidden. When the power cabinet with adjustable internal expansion does not need internal expansion, the spring column 121 extends outward with the insertion key 123. At this time, the insertion key 123 will swing on the swing shaft 122, and then the outward-extending insertion key 123 will be supported under the smooth plate 111 to install the regulator 11 above the cabinet body 14. When the operator needs to expand the internal space of the power cabinet with adjustable internal expansion, he will directly let the side The door 2 swings backward around the side shaft 13 until the side door 2 swings and is completely fixed at the rear of the cabinet 14. Then the user compresses the spring column 121 inward and simultaneously swings the adjuster 11 downward along the upper shaft 141. Then the locking key 113 slides in the expansion cavity 115 and is finally limited in front of the sliding key 112. At this time, the smooth plate 111 is inserted into the bottom end of the limiting plate 143, so that two more expansion cavities 115 will be directly added to the cabinet 14. In this way, the power cabinet with adjustable internal expansion can further expand the space inside the power cabinet without affecting the normal operation of the power cabinet, thereby improving the practicality of the power cabinet with adjustable internal expansion.
