[0002] Electric cabinet is a general term for motor control center, also known as distribution cabinet. Distribution cabinet generally constitutes low-voltage electrical wiring, requiring switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in closed or semi-closed metal cabinets or on screens to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches.

[0003] For example, the utility model with publication number CN214337191 U discloses a power distribution cabinet with adjustable internal space. The utility model relates to the technical field of power distribution equipment, and has the advantages of being able to adjust the height of the internal space to an optimal space, so that the internal space of the cabinet can be adjusted according to the electrical components required to be installed.

[0004] The above-mentioned distribution cabinet with adjustable internal space can change the layout of the internal space by adjusting the internal sliding partitions separately, so that electrical components of different sizes can be installed. However, in actual use, after the cabinet is put into use, if it is necessary to add components to the cabinet, since the internal space is fixed, it is impossible to accommodate the added components, and a larger cabinet needs to be replaced, or another cabinet needs to be installed, which causes inconvenience during use. Therefore, an electric cabinet with adjustable internal space is proposed to solve the above-mentioned problem. Utility Model Content

[0017] Furthermore, a plurality of heat dissipation holes are provided on one side of the movable plate.

[0018] The beneficial effect of adopting the above further solution is that the heat dissipation holes are used to dissipate heat in the space between the inner frame and the outer frame through the movable plate.

[0019] Furthermore, a handle is fixedly connected to one side of the groove plate, and the handle is welded to the groove plate.

[0020] The beneficial effect of adopting the above further solution is that the handle makes it easier for personnel to find the force point when closing or opening the groove plate.

[0021] Furthermore, a dust filter is detachably connected to one side of the movable plate via bolts, and the dust filter is located on one side of the plurality of heat dissipation holes.

[0022] The beneficial effect of adopting the above further solution is that the dust filter is arranged on one side of the plurality of heat dissipation holes, which can reduce the dust from entering the inner frame and the outer frame through the heat dissipation holes and affecting the electronic components installed inside.

[0023] Furthermore, a connecting plate is fixedly connected to one side of the inner frame, a fixing plate is fixedly connected to one side of the connecting plate, and a plurality of mounting holes are provided on one side of the fixing plate.

[0024] The beneficial effect of adopting the above further solution is that the fixing plate is fixed by passing the corresponding fasteners through the mounting holes, and then the inner frame is fixed by the connecting plate, thereby increasing the convenience of its installation.

[0025] Furthermore, both the front and rear sides of the inner frame are fixedly connected with limiting blocks, and both the front and rear sides of the inner wall of the outer frame are fixedly connected with limiting grooves, and the limiting blocks are slidably connected with the limiting grooves.

[0026] The beneficial effect of adopting the above further solution is that when the outer frame moves upward, the limiting block slides in the limiting groove, thereby increasing the stability and smoothness of the movement between the inner frame and the outer frame.
