[0002] The combined power distribution cabinet is an electrical device used to integrate and manage multiple functions in the power system. It consists of multiple units, each of which has different functional modules. The combined power distribution cabinet mainly distributes electricity from the power supply to various electrical equipment and loads to meet different electrical needs. Through switches, contactors and other equipment, it can start, stop and adjust the circuit to ensure the normal operation of the power system. Through the built-in protection device, it monitors the current, voltage and other parameters of the circuit to promptly detect and protect the system from overload, short circuit, leakage and other faults.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:

[0004] (1) Traditional distribution cabinets usually have a fixed structure and layout, and cannot be freely adjusted and assembled according to specific needs, resulting in an inflexible layout and inability to maximize the use of existing space, affecting the design and layout of the electrical system. Since the structure and components of traditional distribution cabinets are relatively fixed and lack customized design, the space utilization rate is low, and some spaces cannot be effectively utilized or the layout is unreasonable, which affects the layout of electrical equipment and the overall space utilization efficiency.

[0005] (2) The complex door opening design makes the maintenance and repair process more difficult. Special tools or professional skills are required to maintain certain distribution cabinets, which increases the maintenance cost and cycle. The complex door opening design increases the manufacturing cost of the distribution cabinet and requires the use of more parts or more complex manufacturing processes, which will lead to an increase in the price of the equipment and affect its market competitiveness.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. This combined power distribution cabinet is prepared in advance with at least two groups of power distribution cabinets. First, the first group of power distribution cabinets and the second group of power distribution cabinets are placed side by side and aligned, and one of the groups of power distribution cabinets is pushed. At this time, the outer wall of the connector one contacts the outer wall of the plug rod. The plug rod subjected to the thrust slides on the surface of the connector one, and the plug rod moves toward the inside of the limit block one, further driving the connecting rod one and the shifting block to move outward. When the protruding end of the plug rod shrinks to the inner wall of the connector two, the outer wall of the connector one fits with the inner wall of the connector two. At this time, the elastic potential energy of the spring two pushes the plug rod to move toward the inside of the connector two, and It is snapped into the slots inside the connector to fix the two groups of distribution cabinets. Conversely, when they need to be disassembled, the two groups of shift blocks are pulled to both sides, and at the same time, any group of distribution cabinets are pulled to separate the two groups of distribution cabinets, thereby achieving the effect that multiple groups of distribution boxes can be quickly and freely disassembled and connected. They can be freely assembled and arranged according to actual needs and site conditions. Components and accessories can be flexibly selected according to different electrical equipment layouts and power requirements, and customized assembly can be performed to meet specific electrical system requirements.

[0016] 2. This combined distribution cabinet, when closing the box door, pushes the box door to fit toward the front of the shell with the hinge as the center. At this time, the clamping block on the back of the box door fits with the inner wall of the claw, and drives the connecting rod 2 to rotate with the connecting rod 3 as the center. At the same time, the claw wraps the clamping block, and the connecting rod 6 inside the connecting rod 2 slides in the groove inside the limiting slide plate, and pulls the limiting slide plate to slide inside the limiting block 2. At the same time, the connecting rod 4 slides inside the limiting slide plate. When the connecting rod 4 slides to the concave point of the slide groove, it is affected by the elastic potential energy of the spring 3 and pulls the limiting slide plate to fix it, thereby achieving the effect of quickly closing the box door. The quick door opening design can greatly shorten the opening time of the distribution cabinet, thereby saving the working time of the maintenance personnel. It is especially important for occasions that require frequent maintenance and overhaul, and can improve work efficiency and production efficiency. The simple and convenient operation method makes users more willing to use such equipment and have a higher evaluation and recognition of its convenience. BRIEF DESCRIPTION OF THE DRAWINGS
