[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] During the use of the distribution cabinet, the internal electrical components may age and be damaged after long-term use, so the internal electrical components need to be replaced or inspected and repaired regularly. However, most of the existing distribution cabinets require hands to go deep into the interior of the distribution cabinet when replacing or inspecting and repairing the internal electrical components. The interior of the distribution cabinet is generally a layered structure, and each layer cannot be pulled out to the outside. Most of the electrical components can only be processed inside the distribution cabinet, but the space between each layer is small, which makes it inconvenient to inspect and repair the distribution cabinet.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. Through the linkage mechanism, connection mechanism, blocking mechanism and limit mechanism and other structures, the movable plate and the fixed plate inside the distribution housing are controlled by the moving rod, so as to drive the electrical components inside the distribution cabinet to move to the outside of the distribution housing, which is convenient for the staff to inspect and replace the electrical components. Moreover, through the setting of the blocking mechanism, the moving rod can move the movable plate in batches, so that it is more convenient to inspect the electrical components without moving all the movable plates out. Through the setting of the connection mechanism, the moving rod is rotated to flip the movable plate, so that the movable plate can stop rotating at any angle, making the inspection more convenient.

[0022] 2. Through the arrangement of the power distribution cabinet, linkage mechanism, limit mechanism and clamping mechanism, it is realized that when the movable rod drives the movable and fixed plates to move, the arc-shaped clamping block is separated from the arc-shaped limit block, so that the limit mechanism no longer limits the movable assembly, so that the movable plate can move, and through the arrangement of the clamping mechanism, the movable groove is sealed, so that the movable plate protects the power distribution housing when it is not moving, which not only makes the movement of the movable plate more stable, but also protects the inside of the power distribution housing and reduces the amount of dust entering, solving the problem in the prior art that when the movable plate moves, it cannot be limited, so the movement is relatively unstable, which may cause the movable plate to separate from the power distribution housing, thereby causing damage to the electrical components;

[0023] 3. By setting up structures such as connecting mechanism, limiting mechanism, clamping mechanism, linkage mechanism and blocking mechanism, it is achieved that when the movable plate is moved, the linkage mechanism and the connecting mechanism cooperate with each other to make the movable plate move to the outside of the distribution shell, and by setting the blocking mechanism, when it moves, the blocking plate is clamped with the threaded rod by the rotation of the clamping cylinder, so that the movable rod can drive the threaded rod to move, thereby driving the fixed plate to move synchronously, so that several fixed plates can be moved in batches by the rotation of the clamping cylinder, so that the movable plate can move individually or multiple plates can move synchronously, which solves the problem in the prior art that when the movable plate is moved out of the distribution shell, the movable plate can only be moved out individually, and if electrical components on multiple movable plates need to be repaired, more movable plates need to be moved, which makes it inconvenient to move the movable plate and makes it inconvenient to repair the electrical components.

Through the setting of the connecting rod 901, when the clamping disc 204 rotates, the blocking plate 902 is driven to rotate synchronously, so that it is clamped with the threaded rod 302. One end of the connecting rod 901 is fixedly connected with a blocking plate 902 corresponding to the through groove. The blocking plate 902 corresponds to the threaded rod 302, and the through groove corresponds to the threaded rod 302. By setting the blocking plate 902, the number of movable plates 304 that can be pulled out can be determined by the number of blocking plates 902 and threaded rods 302 that are clamped together, so that the movable plates 304 can move individually and can also move synchronously as needed, and by setting the clamping disc 204, the movable plates 304 can all move and unfold at the same time, making it more convenient to inspect and repair electrical components, wherein the linkage mechanism 2 includes a movable rod 201 that is slidably connected to the power distribution cabinet 1, and the surface of the movable rod 201 is a path array and is movably connected to a hollow cylinder 202;
