[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model discloses an electric power equipment cabinet with adjustable internal space, including a cabinet body 1 and a plurality of guide grooves 3, wherein a plurality of connecting plates 2 distributed on the inner walls on the left and right sides of the cabinet body 1 are vertically installed in the cabinet body 1, and the plurality of guide grooves 3 are strip-shaped in appearance and are respectively opened on the inner top wall and the inner bottom wall of the cabinet body 1 along the length direction of the cabinet body 1, and each guide groove 3 is combined with the corresponding connecting plate 2 in a T shape, and each guide groove 3 is rotatably and slidably provided with a column 4.

[0026] In one embodiment, the column 4 is a rectangular parallelepiped with a hollow interior, and the side with a longer cross-section is a first mounting surface 41. The two sides of the corresponding first mounting surface 41 on the column 4 are second mounting surfaces 42. A plurality of mounting openings 43 are vertically distributed on the first mounting surface 41 and the second mounting surface 42. The corresponding equipment is installed between the corresponding mounting surfaces of the columns 4 on both sides. A limiting device 5 is provided on the connecting plate 2. The limiting device 5 is used to limit the column 4 after the column 4 is rotated to adjust the corresponding mounting surface.

[0027] During the specific implementation, the staff releases the limit of the column 4 by the limit device 5, so that the column 4 can rotate to the first mounting surface 41 or the second mounting surface 42 facing the middle of the cabinet body 1. When the first mounting surface 41 of each column 4 faces the middle of the cabinet body 1, the distance between the columns 4 on the left and right sides of the cabinet body 1 is larger (i.e. 21 inches). When the second mounting surface 42 of each column 4 faces the middle of the cabinet body 1, the distance between the columns 4 on the left and right sides of the cabinet body 1 becomes smaller (i.e. 19 inches). Therefore, after adjustment, power communication equipment of different sizes can be installed. After the rotation adjustment of the column 4 is completed, it is limited by the limit device 5 to keep it parallel to the connecting plate 2, thereby facilitating the subsequent installation of the corresponding equipment, so that the device can take into account the installation space of 19 inches and 21 inches to meet the installation of different power communication equipment.

[0028] In one embodiment, the cabinet body 1 includes a cabinet body 11 which is rectangular in shape and hollow inside. A cover door 12 is hingedly provided on the cabinet body 11. A copper busbar 13 is provided on the side wall of the cabinet body 11. A plurality of wiring holes 14 are opened on the bottom wall of the cabinet body 11. Each cable passes through the corresponding wiring hole 14 and enters the cabinet body 11. The column 4 is vertically arranged between the top wall and the bottom wall of the cabinet body 11.

[0029] With such a design, the cover door 12 is used to protect the safety of the power communication equipment in the cabinet 11 after being closed. The copper busbar 13 includes a safety grounding copper busbar and a working grounding copper busbar. The safety grounding copper busbar is directly connected to the cabinet 11, mainly to prevent damage to operators caused by leakage. The working grounding copper busbar is isolated from the cabinet by rubber insulating material. The metal casings of the equipment installed in the cabinet should all be connected to the working grounding copper busbar. The wiring holes 14 are used to allow various cables to pass through the wiring holes 14 and enter the cabinet 11.

[0030] In one embodiment, mounting pins 6 are installed on the top and bottom of the column 4 , and each mounting pin 6 can be rotatably inserted into the corresponding guide slot 3 .

[0031] With such a design, when the column 4 is not limited by the limiting device 5 , the column 4 can rotate on the guide groove 3 with the mounting pin 6 as the axis, or move along the opening direction of the guide groove 3 .

[0032] In one embodiment, the limiting device 5 includes a shell 51 which is installed on the connecting plate 2 and has a cylindrical shape and a hollow interior, an adjustment slot 52 which is opened on the shell 51 and has an L-shaped shape, a support rod 53 which is inserted into the shell 51 at one end and can be telescopically slidable, and a limiting plate 54 which is installed at the end of the support rod 53 away from the shell 51 and can pass through the installation opening 43. The limiting plate 54 has a rectangular shape, and the support rod 53 and the limiting plate 54 are combined in a T shape. The limiting plate 54 is used to pass through the installation opening 43 and be clamped with the column 4. A pull rod 55 which passes through the adjustment slot 52 is installed on the support rod 53. A mounting plate 56 is rotatably installed at one end of the support rod 53 located inside the shell 51, and a tension spring 57 which is rotatably connected to the inner wall of the shell 51 at the other end is installed on the mounting plate 56.

[0033] In the specific implementation, the initial state of the limit plate 54 is a horizontal setting. When the column 4 is close to the connecting plate 2, the limit plate 54 will pass through the mounting opening 43 of the corresponding mounting surface and extend to the inside of the column 4. Then, the staff holds the pull rod 55 and rotates it ninety degrees along the horizontal section of the adjustment groove 52, so that the support rod 53 and the limit plate 54 rotate synchronously to become a vertical state. At this time, the limit plate 54 will be stuck in the inside of the column 4, so that the column 4 can be stably fixed on the connecting plate 2, and the tension spring 57 will continue to tighten the support rod 53 to ensure that the limit plate 54 is tightly attached to the inner wall of the column 4 when it is stuck in the inside of the column 4, thereby enhancing the stability of the device installation. Since the tension spring 57 is rotatably connected to the shell 51, and the mounting plate 56 is also rotatably connected to the support rod 53, the support rod 53 will not have an adverse effect on the limit plate 54 when rotating, so as to ensure safe use.

[0034] In one embodiment, an anti-skid sheet is installed on the limiting plate 54. The anti-skid sheet can be a rubber sheet with anti-skid patterns. It fits the inner wall of the column 4 and can be used in conjunction with the tension spring 57 to further prevent the limiting plate 54 from sliding and rotating without cause when it is inside the column 4.
