Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a power distribution transformer integrated distribution cabinet, including, The cabinet assembly 100 includes an outer shell 101, a cover plate 102 fixedly connected to the top of the outer shell 101, a door 103 hinged to the side wall of the outer shell 101, an air conditioner outer shell 104 fixedly connected to the middle of the door 103, and a mounting plate 105 fixedly connected to the inside of the outer shell 101. The mounting plate 105 has mounting holes evenly distributed on its side wall. The docking assembly 200 includes a support base 201 fixedly connected inside the housing 101, a guide rod 202 fixedly connected to the middle side wall of the support base 201, a main crossbeam 203 fixedly connected to the end of the support base 201, a sliding member 204 slidably connected to the side wall of the guide rod 202, a secondary crossbeam 205 fixedly connected to the end of the sliding member 204, and a support beam 206 snapped onto the end of the main crossbeam 203. The upper surfaces of the main crossbeam 203 and the secondary crossbeam 205 are arranged parallel to each other, and the other end of the support beam 206 is snapped onto the end of the secondary crossbeam 205.

[0019] The outer casing 101 forms the foundation of the overall frame, providing a closed protective space for the internal electrical components. A cover plate 102 is fixed to the top of the outer casing 101, serving two purposes: firstly, to block direct sunlight and reduce internal temperature rise, and secondly, to guide water accumulation to the sides, preventing rainwater from seeping into the cabinet. The door 103 is hinged to the side wall of the outer casing 101 and controlled by a lock, facilitating the installation and maintenance of internal equipment while providing complete protection when closed, preventing unauthorized operation or foreign object entry. An air conditioning casing 104 fixed in the middle of the door 103 integrates heat dissipation equipment (such as industrial air conditioners or axial flow fans). The heat dissipation device is fixed in a pre-reserved mounting position, allowing air circulation between the cabinet and the external environment, promptly dissipating the heat generated by the equipment and maintaining the internal temperature within the allowable operating range of the electrical components. The mounting plate 105 inside the outer casing 101 is a vertically fixed perforated plate with evenly distributed mounting holes on its side walls to accommodate electrical components of different specifications. Flexible fixing with bolts meets the diverse component layout requirements of the power distribution system. A support base 201 is fixed to the outer casing 101. 1. The interior (usually connected to the cabinet base plate or side beam by bolts) serves as the load-bearing foundation for the docking components; the guide rod 202 (such as an optical axis or chrome-plated round rod) fixed on its side wall provides a guide track for the sliding member 204, which can slide smoothly along the axial direction of the guide rod 202 to ensure the movement accuracy of the secondary crossbeam 205; the main crossbeam 203 is fixed to the end of the support base 201 and is set parallel to the secondary crossbeam 205 at the end of the sliding member 204. Together, they form a "double beam structure" for equipment support, which distributes the weight of the equipment through symmetrically distributed stress points and avoids deformation of a single crossbeam due to excessive load. The slots on the end sidewalls of the support beam 206 are adapted to engage with the ends of the main crossbeam 203 and the secondary crossbeam 205, achieving quick positioning and connection through a "concave-convex fit". At the same time, the anti-slip texture on the inner side of the slots can enhance friction and prevent the support beam from sliding. The mounting holes on the upper surface of the support beam 206 are used to fix the transformer base (connected by bolts). Multiple sets of support beams can be arranged at intervals along the length of the crossbeams to distribute the weight of the equipment to the main and secondary crossbeams and the support base, and finally transfer it to the bottom of the cabinet, ensuring the load-bearing stability of the overall structure.

[0020] Specifically, the docking assembly 200 also includes a limiting plate 207 fixedly connected to the side wall of the main crossbeam 203, and a guide post 208 inserted into the end of the limiting plate 207. The end of the limiting plate 207 is engaged with the side wall of the support beam 206, and the end of the guide post 208 protrudes from the upper surface of the support beam 206.

[0021] The limiting plate 207 on the side wall of the main crossbeam 203 is engaged with the side wall of the support beam 206. The guide post 208 (the end of which protrudes from the upper surface of the support beam 206) inserted into the end of the limiting plate 207 can play a positioning and guiding role during the installation of the support beam. The guide post is inserted into the pre-set positioning hole of the support beam to ensure that the connection between the support beam 206 and the main and secondary crossbeams is accurately aligned, avoiding uneven force caused by installation deviation.

[0022] Furthermore, the end sidewall of the support beam 206 is provided with a slot for use with the main crossbeam 203 and the secondary crossbeam 205, and the upper end face of the support beam 206 is provided with an installation hole.

[0023] Furthermore, an adjusting seat 209 is fixedly connected to the bottom side wall of the main crossbeam 203. An adjusting rod 210 is rotatably mounted at the center of the adjusting seat 209. A ball nut 211 is fitted to the side wall of the adjusting rod 210. The side wall of the ball nut 211 is bolted to the side wall of the secondary crossbeam 205. A handle 212 is fixedly connected to the end of the adjusting rod 210. The end of the handle 212 extends to the outside of the main crossbeam 203, and the side wall of the handle 212 is provided with an anti-slip groove.

[0024] The adjusting seat 209 at the bottom of the main crossbeam 203 provides rotational support for the adjusting rod 210. The adjusting rod 210 and the ball nut 211 form a helical transmission pair: when the handle 212 at the end of the adjusting rod 210 is rotated, the screw rotates, causing the ball nut 211 to translate axially. The ball nut 211 is connected to the secondary crossbeam 205 by bolts, thereby driving the secondary crossbeam 205 to move closer to or away from the main crossbeam 203 along the guide rod 202 with the sliding member 204, realizing continuous adjustment of the distance between the two. This design can be adapted to transformers or equipment of different widths.

[0025] It should be noted that the side wall of the adjusting seat 209 is threaded with a handle bolt 213, and the end of the handle bolt 213 is engaged with the side wall of the adjusting rod 210.

[0026] The handle bolt 213 on the side wall of the adjusting seat 209 is used to lock the adjusted position: when the beam spacing is adjusted to the correct position, tighten the handle bolt 213, and its end will be inserted into the anti-slip groove on the side wall of the adjusting rod 210 (or directly against the surface of the lead screw). The friction will limit the rotation of the adjusting rod and prevent the beam spacing from shifting due to vibration during equipment operation.

[0027] Preferably, the cabinet assembly 100 further includes a wiring board 106 fixedly connected to the middle of the top of the outer casing 101. The wiring board 106 has a cable outlet on its side wall, and a cover plate 102 is fitted over the outside of the wiring board 106.

[0028] The junction box 106 at the top center of the outer casing 101 serves as a centralized channel for cable entry and exit. The cable outlets on its side walls (with different apertures designed according to cable specifications) can classify and organize the incoming and outgoing cables, preventing them from becoming tangled. The cover plate 102 is fitted over the outside of the junction box 106, forming a double protection. This prevents rainwater from seeping into the cabinet along the cable gaps and also shields the wiring parts from external mechanical damage, ensuring the safety and stability of the cable connection.

[0029] In use, the cover 102 tilts to cover the top of the outer casing, blocking direct sunlight. The door 103 is hinged to the side wall of the outer casing, forming a complete sealed space when closed to prevent unauthorized operation and foreign object intrusion. The air conditioner casing 104 in the middle of the door has a reserved standardized installation position, which realizes air circulation inside the cabinet through integrated heat dissipation equipment, and stabilizes the temperature inside the cabinet within a stable range. The main crossbeam 203 is fixed to the end of the support base 201, and the secondary crossbeam 205 is slidably connected to the guide rod 202 through the sliding member 204. The two form a parallel "double beam support system". During adjustment, turning the handle 212 drives the adjusting rod 210 to rotate, and the ball nut 211 moves along the screw axis, causing the secondary crossbeam 205 to move smoothly along the guide rod 202 with the sliding member 204, realizing continuous adjustment of the distance between the main and secondary crossbeams, which can be adapted to transformers of different specifications. After adjustment, tighten the handle bolt 213 on the side wall of the adjusting seat 209. Its end engages with the side wall of the adjusting rod, and the mechanical locking restricts the rotation of the adjusting rod to prevent the spacing from shifting due to vibration during equipment operation. The limiting plate 207 on the side wall of the main crossbeam engages with the side wall of the support beam 206, and the guide post 208 is inserted into the positioning hole of the support beam to ensure that the support beam is precisely aligned with the crossbeam during installation, avoiding uneven stress. The end slot of the support beam 206 engages with the end of the main and auxiliary crossbeams, and the mounting hole on the upper end face is fixed to the transformer base with bolts. Multiple sets of support beams are arranged at intervals along the length of the crossbeam to distribute the weight of the transformer to the main and auxiliary crossbeams, and then transfer it to the bottom of the cabinet through the support seat, avoiding excessive stress at a single point that could cause structural deformation and ensuring long-term operational stability.

[0030] In summary, the cabinet assembly 100 constructs a closed protective space through its outer shell, cover, and door, working in conjunction with the heat dissipation equipment of the air conditioner casing and the cable management of the terminal block to provide a safe and orderly operating environment for the internal equipment. The docking assembly 200 achieves adjustable spacing between the main and auxiliary crossbeams through adjusting rods and ball nut transmissions. Combined with the slotted connection of the support beams and the positioning of the guide columns, it flexibly adapts to the installation of transformers and equipment of different sizes. At the same time, the handle bolt locking position ensures stable operation. The synergistic effect of both components enables the distribution cabinet to meet the installation needs of diverse power distribution equipment while ensuring the long-term safe operation of the equipment, making it suitable for power distribution systems in industrial plants, residential communities, and other scenarios.
