[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations usually use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets on the low voltage side. The low voltage distribution cabinets are then connected to the distribution boards, control boxes and switch boxes of various power users. The inside of the distribution cabinet is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] The installation process of most electrical components in distribution boxes on the market is cumbersome and inconvenient. Multiple tools must be carried during installation, and they are not easy to disassemble, which affects work efficiency.

[0004] For example, a high and low voltage distribution cabinet. According to the patent specification, the high and low voltage distribution cabinet provided by the present invention adopts a variety of technical solutions, including a distribution cabinet body, a mounting assembly, a protection assembly, a detection module, a control module, a dust removal and heat dissipation module, a dehumidification module, an air cylinder, a fan, a dust removal device, a control valve, an air cylinder and a driving part, a dehumidification module, a heating device, etc. These components each have different functions, such as protecting electrical components, detecting the physical parameter values ​​of the air in the distribution cabinet, controlling the dust removal and heat dissipation module and the dehumidification module to start or shut down, etc. Through the synergistic effect of these components, automatic dust removal, heat dissipation and dehumidification of the high and low voltage distribution cabinet are realized, and work efficiency and practicality are improved.

[0005] The above invention simplifies the installation process of electrical components by setting up installation components, thereby improving work efficiency. However, the high and low voltage distribution cabinets themselves are large in size and weight, and in actual use, multiple distribution cabinets are usually used in combination. It is not suitable for the situation where cabinet doors are opened on both sides of the above distribution cabinets, so it is necessary to improve the installation efficiency of the high and low voltage distribution cabinets. Summary of the invention

A quick mounting structure is arranged at each mounting position, and the electrical components are quickly mounted on the mounting position through the quick mounting structure.

[0008] By adopting the above technical solution, various parts of the distribution cabinet body, such as the side panels, rear sealing plate, fixing rods and cover plates are detachably connected to the base. During installation, the first mounting blocks of the side panels and rear sealing plates are first installed in the first mounting grooves provided on the base, and then the fixing rods are installed on the base in correspondence with the limiting grooves of the fixing rods and the side edges of the side panels and rear sealing plates to achieve the connection between the side panels, rear sealing plates and fixing rods. Then, the fixing rods are fixed above the base by the first fixing members provided on the base, and at the same time, the side panels and rear sealing plates are limited to prevent the side panels and rear sealing plates from moving. Then, the cover plates are fixed by the second fixing members. The mounting plate is fixed on the top of the fixing rod to complete the installation of the distribution cabinet body. A slide rail is arranged on the top of the base. The slider under the mounting frame is aligned with the slide rail and made to slide along the slide rail to realize the connection between the mounting frame and the base. Then, multiple mounting positions are arranged on the mounting plate, and a quick mounting structure is arranged on each mounting position. The electrical components are quickly installed on the mounting position through the quick mounting structure.

The sub-panel is installed in the mounting groove of the adjacent sub-panel through the second mounting block to fix the two adjacent sub-panels.

[0010] By adopting the above technical solution, a modular design is achieved by splitting the side panels and the rear cover panel into multiple sub-panels. The adjacent sub-panels are spliced ​​and fixed by the second mounting block and the second mounting groove. The installation of the side panels and the rear cover panel can be quickly completed through simple splicing and fixing methods, thereby improving the installation efficiency. At the same time, the splicing design can adapt to the needs of different sizes and shapes, thereby improving the adaptability and customizability of the product.

[0011] Preferably, the first mounting block and the second mounting block are configured as T-shaped blocks having the same shape and size.

[0012] By adopting the above technical solution, the first mounting block and the second mounting block are set to have the same shape and size, so as to achieve standardized design and simplify the production and assembly process. Since the two mounting blocks are exactly the same, they can be easily interchanged when replacement or repair is required, thereby reducing maintenance costs. The T-block has good structural stability and can withstand greater forces and torques, thereby ensuring the stability of the installation. At the same time, the same shape and size make the installation process more intuitive and convenient, reducing the possibility of installation errors.

[0013] Preferably, the first mounting groove and the second mounting groove are configured as a T-slot adapted to the T-block and a splicing groove located at one end of the T-slot, and the splicing groove is for the T-block to slide into the T-slot after being inserted.

[0014] By adopting the above technical solution and setting the splicing groove, the T-block can be first inserted into the splicing groove and then easily slid into the T-slot, which simplifies the installation process, thereby reducing the installation time and improving the installation efficiency. At the same time, the T-shaped structure itself has strong shear and torsion resistance, so such a design can enhance the stability of the overall structure.

[0015] Preferably, the first mounting groove and the first mounting block and the second mounting groove and the second mounting block are arranged in three groups along the length direction of the sub-board.

[0016] By adopting the above technical solution, through the cooperation of multiple sets of mounting grooves and mounting blocks, the connection stability between the sub-board and other structural parts can be greatly improved, the stress can be effectively dispersed, and single point failure can be prevented, thereby enhancing the stability of the overall structure. Multiple sets of mounting grooves and mounting blocks mean more positioning points, which helps to improve the relative position accuracy between the components and ensure that the assembled product meets the design requirements of size and shape.

[0017] Preferably, the first fixing member includes a fixing block, a control handle and a compression spring, and an intermediate rod connected to the fixing block and the control handle; the base is provided with a movable groove for the fixing block to move; the control handle is arranged on the outside of the base; the compression spring is arranged in the middle of the fixing block and the movable groove close to the control handle; the fixing rod is provided with a fixing groove for the fixing block to pass through; during installation, the fixing block is inserted into the fixing groove to fix the fixing rod; during disassembly, the control handle is pulled to separate the fixing block from the fixing groove.

[0018] By adopting the above technical solution, the connection and disengagement of the fixing block and the fixing groove can be easily achieved through the operation of the control handle, thereby meeting the needs of quick installation and disassembly. In the installed state, the fixing block is inserted into the fixing groove, and a stable fixing force is maintained through the action of the compression spring to ensure that the fixing rod does not move accidentally, reducing the loosening or falling off of the fixing rod during use, thereby improving the safety of operation. The control handle is set on the outside of the base for easy user operation. At the same time, the design of the movable groove provides a clear path for the movement of the fixing block, simplifying the operating steps.

[0019] Preferably, the fixing block is arranged in a square shape, and an inclined surface is arranged at one end of the fixing block away from the middle rod.

[0020] By adopting the above technical solution, the setting of the inclined surface can play a guiding role. When the fixing block needs to be inserted into the fixing groove, the inclined surface can help the user to align and insert it more easily, thereby improving the convenience of operation. The stability of the square and the guiding insertion function of the inclined surface jointly enhance the user experience during use, making the fixing operation smoother and more efficient.

[0021] Preferably, the slide rails are provided in two numbers, and the two slide rails are arranged in parallel.

[0022] By adopting the above technical solution and setting two parallel slide rails, a more stable support can be provided for the installation frame to prevent it from shaking or shifting during use, which helps to maintain the stability of the installation frame during the sliding process and reduce sticking and friction. The two slide rails can disperse the weight of the installation frame and the electrical components thereon, thereby improving the bearing capacity of the entire structure.

[0023] Preferably, sliding grooves for the mounting plate to move up and down are provided on both sides of the mounting frame, a threaded hole is provided on the side where the mounting plate is in contact with the mounting frame, and screws passing through the sliding grooves are provided on the side of the mounting frame away from the mounting plate, and the mounting plate is fixed by connecting the screws and the threaded holes provided on the mounting plate.

The combined design of the slide groove and the threaded hole simplifies the installation steps. The user only needs to move the mounting plate to the appropriate position and then tighten the screws to complete the installation, which greatly improves the installation efficiency.

[0025] Preferably, the mounting position is arranged as a T-shaped structure along the length direction of the mounting plate, a T-shaped slot is provided on the quick mounting structure, the electronic components are fixedly connected to the quick mounting structure, are quickly mounted on the T-shaped structure through the T-shaped slot, and move along the length direction of the mounting plate.

[0026] By adopting the above technical solution and the matching design of the T-shaped structure and the T-shaped slot, the electronic components can be quickly aligned and installed at the designated position, which greatly improves the installation efficiency.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The various parts of the power distribution cabinet body, such as the side panels, rear sealing plate, fixing rod and cover plate, are detachably connected to the base. During installation, first install the first mounting block of the side panels and rear sealing plate into the first mounting groove opened on the base, then install the fixing rod to the base in correspondence with the side edge of the fixing rod limit groove and the side of the side panel and rear sealing plate to realize the connection between the side panel, rear sealing plate and the fixing rod, then fix the fixing rod above the base through the first fixing piece provided on the base, and limit the side panels and rear sealing plate at the same time to prevent the side panels and rear sealing plate from moving, and then fix the cover plate to the fixed position through the second fixing piece.
