The waterproof adapter box 24 is existing technology, and the matching waterproof cover is discarded. The third cabinet 23 has a cable passage opening, and then the cable pass cover is inverted and placed on the third cabinet 23 to fit together, and locked on the third cabinet 23 with screws. Waterproof glue needs to be applied to the gap between the waterproof adapter box 24 and the third cabinet 23 and the position of the mounting screws.

[0021] Please see Figure 1-4 A further embodiment of this solution is as follows: a guide rod is provided on the side of the fixed hook 31 facing the movable hook 32, and a spring 34 is sleeved on the guide rod to push the movable hook 32 away from the fixed hook 31. The movable hook 32 is provided with a guide hole corresponding to the guide rod. The guide rod and the guide hole form a guide structure to ensure that the movable hook 32 slides smoothly and does not deviate; the spring 34 provides an automatic reset force, so that the hook remains open when not subjected to external force, realizing a quick installation operation of "one push and it closes", improving assembly convenience and repeated use stability.

[0022] Please see Figure 2-5 A further solution based on this embodiment is as follows: a positioning plate 33 is installed on the connecting plate 15. The positioning plate 33 has a circular groove corresponding to the guide rod, and an insertion hole 331 is provided on the positioning plate 33. A rod can be inserted into the insertion hole 331 to push the movable hook 32 toward the fixed hook 31. The insertion hole 331 structure provides a convenient unlocking method. By inserting the rod, the spring 34 can be compressed and the hook can be released. The insertion hole 331 helps to prevent the rod from slipping on the surface of the movable hook 32, providing a limiting function.

[0023] Please see Figure 2-5A further solution based on this embodiment is as follows: a stud 41 engages at the top of the upper plate 14, a pressure plate is integrally formed at the bottom of the stud 41, a nut 42 engages at the outer diameter of the stud 41 to tighten the threads of the stud 41 and the upper plate 14, a hexagonal hole 411 is provided on the stud 41 for rotating the stud 41, and a positioning ring 231 corresponding to the pressure plate is provided on the third cabinet 23. By rotating the stud 41 to drive the pressure plate to press down, a controllable preload can be applied to the top cabinet to ensure its stable fixation; the hexagonal hole 411 is designed for easy adjustment with an Allen wrench; the locking nut 42 prevents loosening due to vibration and improves connection reliability; and the positioning ring 231, together with the nut 411, achieves precise alignment and tightening, enhancing the overall structural stability.

[0024] Please see Figure 2-5 A further solution based on this embodiment is as follows: positioning grooves are respectively provided at the bottom of the first cabinet 21, the second cabinet 22, and the third cabinet 23, and corresponding second positioning blocks 25 are respectively provided at the top of the first cabinet 21 and the second cabinet 22. Mechanical alignment is achieved between the upper and lower cabinets through the positioning blocks and positioning grooves, ensuring accurate positioning and no deviation during stacking and installation, thereby improving modular assembly efficiency and structural consistency.

[0025] Please see Figure 2-5 A further solution based on this embodiment is as follows: the top of the first cabinet 21 is provided with a first cable passage hole 211, the bottom of the third cabinet 23 is provided with a third cable passage hole 232, and the top and bottom of the second cabinet 22 are respectively provided with annular retaining edges 222. The annular retaining edges 222 can be inserted into the first cable passage hole 211 of the first cabinet 21 or the third cable passage hole 232 of the third cabinet 23; the inner wall of the annular retaining edges 222 is provided with a second cable passage hole 221. The annular retaining edges 222 and the cable passage holes form a "plug-in labyrinth seal" channel, which effectively extends the moisture intrusion path and prevents moisture and dampness from spreading vertically along the cable to adjacent cabinets, achieving high sealing performance of the cable channel between cabinets. A sealing gasket can also be fitted on the annular retaining edges 222.

[0026] Working principle: First, the entire appliance cabinet is moved to the designated installation position using the casters 12 and secured with brakes on the casters 12. The first positioning block on the lower frame plate 11 is used for initial positioning of the first cabinet 21. Then, the first cabinet 21 is placed on the lower plate 11 to complete the basic installation. The second positioning block 25 on the top of the first cabinet 21 engages with the positioning groove at the bottom of the second cabinet 22 to achieve vertical alignment and stacking. Similarly, the second positioning block 25 on the top of the second cabinet 22 engages with the positioning groove at the bottom of the third cabinet 23 to complete the positioning and installation of the top cabinet. This positioning structure ensures accurate vertical alignment of each cabinet, preventing misalignment. During the cabinet stacking process, the second cabinet 21... 2. The top and bottom annular flanges 222 are respectively inserted into the first cable passage hole 211 of the first cabinet 21 and the third cable passage hole 232 of the third cabinet 23, forming a vertically continuous cable channel. The inner wall of the annular flange 222 is provided with a second cable passage hole 221 to allow the cable to pass through. This plug-in structure, together with the sealing gasket that can be fitted on the annular flange 222, forms a labyrinth seal, effectively blocking moisture. After the cabinets are stacked, the hexagonal hole 411 on the rotating stud 41 drives the stud 41 to move downward, so that the integrated pressure plate at its bottom is gradually pressed and passes through the positioning ring 231 on the third cabinet 23, realizing the vertical pressing and fixing of the top cabinet. Then, the nut on the outer diameter of the stud 41 is tightened. 42 uses a locking thread connection to prevent loosening due to equipment vibration, thus ensuring the overall structural stability and reliability. Simultaneously, the connection between the electrical cabinet and external racks or other equipment is achieved through a quick-release assembly. After aligning the connecting plate 15 with the rack mounting position and pushing it, the fixed hook 31 and the movable hook 32, under the action of the guide rod and spring 34, engage with the rack holes. The spring 34 pushes the movable hook 32 back to its original position, allowing the two hooks to clamp the rack quickly and lock together, completing tool-free quick-release. When disassembly is required, insert a rod through the insertion hole 331 to push the movable hook 32 against the spring force of the spring 34, moving it towards the fixed hook 31. After all cabinets are installed, cover the front opening of the cabinet with the sealing cap 20 to seal it. The cover 20 presses the sealing ring 511 on the sealing edge 51 to form a surface contact seal. Then, use a torque wrench to tighten the fixing screws to ensure uniform pressure and increase the sealing performance. For the part where the cable needs to be led out, install a waterproof adapter box 24 at the cable passage on the side wall of the third cabinet 23. After removing the original waterproof cover, invert the waterproof adapter box 24 onto the cable passage and lock it with screws. At the same time, apply waterproof glue to the joint between the waterproof adapter box 24 and the third cabinet 23 and the screw holes to further improve the sealing performance. The cable is led out from the exit hole to realize the external connection. A desiccant can also be placed inside the first cabinet 21, the second cabinet 22, and the third cabinet 23. The desiccant inside can be replaced during regular maintenance.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
