[0026] Split-type pull-out power distribution cabinet equipment, such as Figures 1-3As shown, the device includes an outer casing 10 and several internal cabinets 20 installed inside the outer casing 10. A pull rod 30 for pulling out the internal cabinets 20 is installed on one bottom side of the outer casing 10. Several sets of evenly spaced pull-out grooves 12 are provided on the top and bottom of the outer casing 10. Positioning bolts 11 corresponding to the positions of the pull rods 30 are installed on the bottom of the outer wall of the outer casing 10. Pull-out slide seats 23 that are adapted to the size of the pull-out grooves 12 and are slidably engaged are installed on the top and bottom of the internal cabinets 20. A connecting seat 24 is provided at the bottom of the pull-out slide seat 23 at the bottom of the internal cabinet 20. The end of the pull rod 30 is rotatably connected to the connecting seat 24. Threaded rods 32 that are adapted to the size of the positioning bolts 11 and are threadedly connected are provided at both ends of the pull rod 30. The outer casing 10 provides structural support and protection for the overall equipment. The internal cabinets 20 installed inside the outer casing 10 facilitate modular management of electrical components. A pull-out rod 30 installed on the bottom side of the outer casing 10 facilitates the operation of pulling out and pushing in the inner cabinet 20. Several sets of evenly spaced pull-out grooves 12 on the top and bottom of the outer casing 10 are adapted to and slide in conjunction with the pull-out slide blocks 23 installed on the top and bottom of the inner cabinet 20, ensuring the smoothness and stability of the pull-out process. Positioning bolts 11 corresponding to the position of the pull-out rod 30 are installed on the bottom of the outer wall of the outer casing 10, and threaded rods 32 at both ends of the pull-out rod 30, adapted to the size of the positioning bolts 11 and threadedly connected, can fix the inner cabinet 20 in place when it is pulled to the appropriate position. A connecting seat 24 at the bottom of the pull-out slide block 23 at the bottom of the inner cabinet 20 is rotatably connected to the end of the pull-out rod 30, allowing the pull-out rod 30 to rotate flexibly, facilitating the operation of the cabinet. The overall design improves the ease of use and maintenance efficiency of the distribution cabinet equipment.

[0027] It is worth noting that the cross-sections of both the pull-out slide 12 and the pull-out slide base 23 are isosceles trapezoids, which allows the split cabinet 20 to maintain better stability during the pull-out process, making it less prone to shaking or derailment, thus ensuring the smoothness and reliability of the pull-out operation.

[0028] Furthermore, a partition 13 is installed between every two adjacent cabinets 20, and flame-retardant plates 14 are provided on both sides of the partition 13. The partition 13 separates each cabinet 20, enabling independent partitioning of electrical components, while the flame-retardant plates 14 can effectively prevent the spread of fire between the cabinets 20, thus improving the safety of the equipment.

[0029] Specifically, each cabinet 20 has a door 21 connected to one side by a hinge. A handle 22 is installed on the outer wall of the door 21. The door 21 can seal and protect the electrical components inside the cabinet 20, preventing dust, foreign objects, etc. from entering. The handle 22 makes it convenient for operators to open and close the door 21, facilitating the operation and maintenance of the internal components.

[0030] The pull rod 30 is connected to the connecting seat 24 by a bearing 25. The bearing 25 allows the pull rod 30 to rotate flexibly, reducing friction during the pulling process and making it easier for operators to pull out the split inner cabinet 20, thus improving the convenience of operation.

[0031] In addition, a pull ring 31 is installed at the end of the pull rod 30 away from the connecting seat 24. The pull ring 31 provides an easy part for the operator to hold and apply force, making the pull operation more convenient and further improving the ease of use of the equipment.

[0032] Working principle of this split-type pull-out power distribution cabinet:

[0033] First, when it is necessary to operate or maintain the electrical components inside the cabinet 20, the operator holds the pull ring 31 at the end of the pull rod 30 and applies outward pulling force. Since the pull rod 30 and the connecting seat 24 under the bottom pull slide 23 of the cabinet 20 are rotatably connected by the bearing 25, under the action of pulling force, the cabinet 20 slides smoothly outward along the pull slide groove 12 on the outer shell 10 through the pull slide 23 at its top and bottom.

[0034] After the inner cabinet 20 is pulled out to the appropriate position, rotate the threaded rods 32 at both ends of the pull rod 30 to make them threadedly connected with the positioning bolts 11 at the bottom of the outer wall of the outer shell 10, thereby realizing the positioning and fixing of the inner cabinet 20.

[0035] Next, the cabinet door 21 is opened using the handle 22 on one side of the cabinet door 21 of the internal cabinet 20 to perform relevant operations on the internal electrical components. The partition 13 and flame-retardant plate 14 between adjacent internal cabinets 20 can ensure the independence and safety of the electrical components in each zone.

[0036] After the operation is completed, rotate the threaded rod 32 in the opposite direction to separate it from the positioning bolt 11, then push the inner cabinet 20 back into the outer shell 10, and connect it to the positioning bolt 11 by threading the threaded rod 32 at the other end. Finally, close the cabinet door 21.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
