[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] A pull-out DC power distribution cabinet includes an outer cabinet 1. A movable tray 2 is installed inside the outer cabinet 1. Fixed guide rails 3 are provided on both sides of the bottom of the movable tray 2. The fixed guide rails 3 are detachably installed on the side wall of the inner cavity of the outer cabinet 1. Mounting grooves 4 are provided on both sides of the bottom of the movable tray 2. Rollers 5, evenly spaced, are rotatably installed inside the mounting grooves 4. A positioning spring 8 is fixedly installed on one side of the top of the fixed guide rail 3. Positioning blocks 6 are detachably installed at both ends of the top side of the movable tray 2. The bottom of the positioning block 6 has a groove 7 that matches the positioning spring 8. The top of the fixed guide rail 3 has a mounting groove 11 that matches the rollers 5.

[0031] The specific usage process is as follows: It should be noted that the rear side of the outer cabinet 1 is provided with heat dissipation holes to ensure that the electrical components inside the distribution cabinet are not damaged by high temperatures. In addition, the structure of the entire U-shaped cabinet panel 12, besides the perforated plate structure used in this article, can also adopt a large-spacing grille structure design, thereby maximizing the space reserved for user maintenance operations and providing convenience for user maintenance work. When maintaining the distribution cabinet, first grasp the handle 20 and lift it upwards, and then you can lift the cabinet door 18 upwards with the help of the handle 20. The two sliding pins 19 at the top of the cabinet door 18 will slide in the corresponding slide grooves 17, and the sliding pins 19 are round, so they can also move freely and flexibly at the turns inside the slide grooves 17. By rotating the cabinet door 18, it can be lifted and adjusted to a horizontal position, allowing it to be pushed to the top of the outer cabinet 1 to open. This retracts the cabinet door 18 to the top of the outer cabinet 1, thus avoiding interference with user maintenance and providing convenience. Opening the cabinet door 18 reveals the inner cabinet, which consists of a movable support plate 2, a U-shaped cabinet panel 12, and a top panel 13. After opening the cabinet door 18, the user can simply grasp the U-shaped cabinet panel 12 and move it outwards. The movable support plate 2 slides on two fixed guide rails 3 while moving, and rollers 5 are installed on both sides of the bottom of the movable support plate 2, within mounting grooves 11 on the fixed guide rails 3. The fixed guide rail 3 can limit the movement of the movable tray 2, and with the action of the roller 5, the movable tray 2 can slide more flexibly on the fixed guide rail 3, making it easier to open the inner cabinet and providing convenience and assistance for users. When the movable tray 2 moves, the positioning block 6 also moves along with it, and the roller 10 rolls within the mounting groove 11. Thus, the fixed guide rail 3 can also limit the movement of the positioning block 6, ensuring its stability and providing convenience and assistance for users. When the positioning block 6 moves with the movable tray 2, the positioning spring 8 will move out of the groove 7. During this process, the groove 7 will deform by squeezing the positioning spring 8 to adjust the position of the groove 7. After the inner cabinet adapts, it will be moved to the outside, allowing users to maintain and repair the electrical components inside the distribution cabinet without restriction, providing convenience for users' work. After maintenance and repair, the inner cabinet will be pushed into the outer cabinet 1. During operation, simply push the U-shaped cabinet plate 12. The U-shaped cabinet plate 12 will drive the moving tray 2 to slide on the two fixed guide rails 3. At the same time, the positioning block 6 will also move with the moving tray 2. Rollers 1 5 and 2 10 roll within the mounting groove 2 11. As the positioning block 6 moves, it will first contact and compress the positioning spring 8. Then, the positioning block 6 continues to move until the groove 7 aligns with the positioning spring 8. Finally, the positioning spring 8 returns to its original position and locks into the groove 7.This fixes the positioning block 6 in place, securing the inner cabinet within the outer cabinet 1 for protection. Finally, the handle 20 is grasped to pull the cabinet door 18 back and close it. This method of moving electrical components from the distribution cabinet to the outside for maintenance and repair allows users to perform maintenance in a more open space, without physical limitations due to confined space. The groove 9 is for installing the roller 10. When the moving tray 2 moves, the positioning block 6 also moves, causing the roller 10 to roll within the mounting groove 11, thus securing the positioning block 6. The U-shaped cabinet 12 serves as a limit switch, ensuring the stability of the positioning block 6 and the movable tray 2 during movement, providing convenience for users. The U-shaped cabinet 12 has evenly and densely distributed pre-installed holes, allowing it to not only dissipate heat but also install electrical components in any position and arrange them arbitrarily, facilitating user installation. The top plate 13 blocks foreign objects and liquids from above, protecting the electrical components inside the U-shaped cabinet 12 and providing convenience for user installation. When the U-shaped cabinet 12 moves, it simultaneously moves the fixing frame 14, thus ensuring the rollers 16 are tightly secured. The sliding mechanism rolls along the inner wall of the top of the outer cabinet 1, supporting the U-shaped cabinet panel 12 and improving its flexibility of movement, thus providing convenience for users. When the cabinet door 18 is opened, the two sliding pins 19 at the top of the door 18 slide within their corresponding grooves 17. These pins 19 also rotate flexibly when they reach the bend in the groove 17, allowing the door 18 to be easily rotated. Finally, users can easily push the door 18 to the top of the outer cabinet 1 for temporary placement, ensuring unobstructed removal of electrical components from the outer cabinet 1, thus facilitating maintenance and repair. The handle 20 is for users to grip when opening the cabinet door 18, allowing them to lift the door more easily and quickly for maintenance and repair, thus facilitating the user's maintenance work. The ramp 21, located on the top of the outer cabinet 1, is used to guide and drain accumulated water. When the distribution cabinet is operating outdoors, rainwater will drain along the ramp 21 to the ground, preventing rainwater from entering the cabinet and damaging electrical components. The ramp 21 can be designed with an inclination angle of five degrees, ten degrees, etc., depending on actual working needs, providing convenience for the user.

[0032] Therefore, the design adopts a built-in pull-out structure, in which all electrical components inside the distribution cabinet are installed in a movable built-in cabinet. During maintenance, the inner cabinet can be pulled out to the outside for maintenance work, so that the working posture is not restricted by the confined space, thereby improving the maintenance speed and efficiency of the distribution cabinet and providing convenience for users.

[0033] A groove 9 is provided on one side of the bottom of the positioning block 6, and a roller 10 is rotatably installed on the inner side of the groove 9.

[0034] Specifically, the groove 9 and the roller 10 are designed so that the groove 9 is used to install the roller 10. When the moving tray 2 moves, the positioning block 6 will also move along with it, and the roller 10 will also roll in the mounting groove 11 at the same time, thereby limiting the positioning block 6 and ensuring the stability of the positioning block 6 and the moving tray 2 when they move, thus providing convenience for the user's work.

[0035] A U-shaped cabinet panel 12 is fixedly installed on the top of the movable pallet 2, and a top plate 13 is fixedly installed on the top of the U-shaped cabinet panel 12.

[0036] Specifically, the U-shaped cabinet panel 12 and the top panel 13 are designed with evenly distributed and densely distributed pre-installed holes on the U-shaped cabinet panel 12. This allows the U-shaped cabinet panel 12 to not only have heat dissipation function, but also to allow electrical components to be installed in any position and arranged arbitrarily, providing convenience for users' installation work. The top panel 13 can block foreign objects and liquids from above, thereby protecting the electrical components inside the U-shaped cabinet panel 12 and providing convenience for users' installation and use.

[0037] Both sides of the U-shaped cabinet panel 12 can be detachably installed with a fixing frame 14. The top of the fixing frame 14 is provided with a mounting groove 3 15, and a roller 3 16 is rotatably installed inside the mounting groove 3 15.

[0038] Specifically, the arrangement of the fixing frame 14, mounting groove 3 15, and roller 3 16 means that when the U-shaped cabinet panel 12 moves, it will simultaneously drive the fixing frame 14 to move. In this way, the roller 3 16 will roll close to the inner wall of the top of the outer cabinet 1, thereby supporting the U-shaped cabinet panel 12 and improving the flexibility of the U-shaped cabinet panel 12's movement, providing convenience for the user's work.

[0039] The front side of the outer cabinet 1 is provided with a cabinet door 18. Sliding pins 19 are fixedly installed on the top and bottom of both sides of the cabinet door 18. Sliding grooves 17 that are adapted to the sliding pins 19 are opened at both ends of the top of the inner side of the outer cabinet 1.

[0040] Specifically, the sliding groove 17, cabinet door 18, and sliding pin 19 are designed such that when the cabinet door 18 is opened, the two sliding pins 19 located at the top of the cabinet door 18 will slide within the corresponding sliding groove 17. At the same time, when the sliding pins 19 move to the bend in the inner cavity of the sliding groove 17, they can also rotate flexibly, thereby allowing the cabinet door 18 to flexibly change direction. Finally, it is convenient for users to push the cabinet door 18 to the top of the outer cabinet 1 for temporary placement, ensuring that the electrical components inside the outer cabinet 1 can be moved out without obstruction, providing convenience and assistance for users' maintenance and repair work.

[0041] Two handles 20 are fixedly installed on the bottom of the outer side of the cabinet door 18.

[0042] Specifically, the handle 20 is designed for users to grip when opening the cabinet door 18, allowing them to lift the cabinet door 18 more easily and quickly open it for maintenance and repair, thus providing convenience for users' maintenance and repair work.

[0043] The top of the outer cabinet 1 is provided with a ramp 21, and the inclination angle of the ramp 21 is five to ten degrees.

[0044] Specifically, the ramp 21 is set on the top of the outer cabinet 1 and is used to guide the drainage of accumulated water. When the distribution cabinet is working outdoors, the rainwater will be discharged to the ground along the ramp 21, thereby preventing rainwater from entering the cabinet and damaging the electrical components. The inclination angle of the ramp 21 can be designed to be five degrees or ten degrees, etc. The specific angle can be determined according to the actual working needs, providing convenience for users.

[0045] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
