[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A multi-layer folding and assembly mechanism is set up. Through the cooperation of lifting screw, lifting column, support arm, guide rod, sliding plate, rotating frame and bonding plate, the folding side plates on both sides of the back panel can be simultaneously rotated and unfolded or folded around the concave hinge seat. This realizes the rapid modular splicing of the distribution box components, improves the convenience of component replacement, and when unfolded, the side partition and sliding splicing plate slide relative to each other at one end of the central partition, and forces the multi-section telescopic sleeve rod to extend and retract, forming lateral support. At the same time, it protects the internal folding components to prevent damage to the folding components when installing electronic components. By using the combination of rotating cabinet doors, telescopic support rods, double door panels and compression springs, the two double door panels are pushed to press against each other when the door is closed, ensuring the sealing effect of the cabinet door. When folding, the double door panels and rotating cabinet doors are rotated in the opposite direction to fit against the outside of the folding side panel. Then, the compression springs press the double door panels against the frame to achieve the limiting and fixing of the door panels after folding. Simultaneously, when the folding side panel, along with the side partition and center partition, are stacked together, rotating the double-acting screw causes the two locking pins to move in opposite directions, engaging with the limiting buckles on the folding side panel for secure fixing. This effectively prevents the folding side panel and rotating cabinet door from accidentally unfolding during transportation and handling, ensuring safety in the folded state. Through the cooperation of the internal tensioning plate, connecting plate and rebound spring, the sealing strip is always tightly fitted to the end face of the back panel when pulled, and the fitting surface is provided with anti-slip vertical grooves, which improves the waterproof and dustproof performance of the splicing area.

[0015] 2. A flip-folding and bottom-sealing mechanism is set up. Through the cooperation of the tension spring, connecting pull plate and reset slide plate in the fixed frame, the rotating support, outer sealing frame and inner sealing frame are moved to facilitate the sealing and fitting of the top and bottom of the assembled distribution box. Then, the drive main shaft and bevel gear drive the drive sleeve, push rod and locking plate to accurately embed into the locking groove of the folding side plate to form a reliable lock and ensure the sealing of the distribution box when unfolded. When folding, the lock can be quickly released by reverse drive and the tension spring can be used to pull the outer sealing frame to automatically reset, making it easy for the positioning pin to be inserted into the slot. This ensures the stability of the outer sealing frame after flipping and folding, and further reduces the overall footprint.

[0016] In summary, the modular assembly of the distribution box components is achieved through the cooperation of multi-layer folding and assembly mechanisms and flip-folding and bottom-sealing mechanisms. This ensures rapid unfolding and bidirectional folding of components, improving the convenience of assembly. When unfolded, the components automatically form lateral supports and lock the top and bottom, ensuring the stability of the assembled distribution box structure and improving the sealing effect. When folded, the components move together and lock themselves, preventing them from falling apart during transportation and ensuring transportation stability. This makes the overall operation simple and tool-free, significantly improving the portability, installation efficiency, and safety of the distribution box. Attached Figure Description

The outer sealing frame 407 has symmetrical insertion holes at one end, and the opening position of the insertion holes corresponds to the installation position of the positioning pins 418.

[0022] The working principle and usage process of this invention are as follows: First, when in use, the lifting screw 302 inside the adjustment frame 301 is rotated, pushing the lifting column 303 to slide upward inside the adjustment frame 301. With the cooperation of the support arm 304, the sliding push plate 306 is moved, which drives the guide rod 305 and the sliding plate 307 to move. Then, with the cooperation of the rotating frame 308 and the bonding plate 309, the folding side plate 2 and the hinge block 311 are pulled to rotate along the concave hinge seat 310, thereby supporting the folding side plate 2 and making it perpendicular to the back plate 1. Simultaneously, the rotation of the folding side panel 2 and the bonding plate 309 pulls the side partition 315 and the sliding splicing plate 316 to slide along the central partition 318, adjusting the distance between the two side partitions 315, and pulling the multi-section telescopic sleeve rod 317 to extend, making the central partition 318 parallel to the side partition 315, facilitating cooperation, forming a lateral support between the two folding side panels 2, and further improving the positional stability between the folding side panel 2 and the back panel 1; Next, by utilizing the cooperation of the anti-deviation guide rod 402, the reset slide plate 403 and the tension spring 404 inside the fixed frame 401, it is convenient to push the rotating support 406, the connecting pull plate 405 and the outer sealing frame 407 to slide, release the connection between the positioning pin 418 and the insertion hole, and facilitate the rotation of the outer sealing frame 407, forcing the outer sealing frame 407 to rotate and fit against the top and bottom of the back panel 1, so that the back panel 1 and the folding side panel 2 are filled between the outer sealing frame 407 and the inner sealing frame 408, ensuring the sealing performance after splicing; Next, the drive spindle 415 rotates and transmits power through the bevel gear 416, driving the drive sleeve 410 to rotate, which in turn pushes the push rod 411, guide push plate 412 and locking plate 413 to move, forcing the locking plate 413 to embed into the locking groove 414 on the folding side plate 2, thereby fixing the position between the outer sealing frame 407, the folding side plate 2 and the back plate 1, completing the assembly of the distribution box, and ensuring the stability and strength of the distribution box after splicing. Next, with the help of the spring 329, the tensioning plate 326 is easily pushed to slide inside the frame 325, and with the help of the connecting plate 327, the sealing strip 328 is pulled to move and fit tightly against one end of the back panel 1. The sealing strip 328 and the back panel 1 are provided with anti-slip texture, which improves the sealing effect and limits the folding side panel 2 and the back panel 1, ensuring the vertical effect. Then, with the cooperation of the positioning door frame 313, it is convenient to rotate the two rotating cabinet doors 314 to align. Then, by utilizing the extension and retraction characteristics of the compression spring 324, the double door panels 323 and the telescopic support rod 322 are pushed to slide and fit together, ensuring the sealing between the cabinet doors and preventing dust from entering. Next, when folding is required, the two double-door panels 323 are pulled apart, and then the double-door panels 323 and the rotating cabinet door 314 are rotated by the telescopic support rod 322, so that they are folded and fit against the outside of the folding side panel 2. And because of the telescopic characteristics of the compression spring 324, the double-door panels 323 are pushed to fit tightly against one end of the frame 325, so that the double-door panels 323 and the frame 325 are engaged, ensuring the effect after folding. Then, the drive spindle 415 is rotated in reverse, and moves through the bevel gear 416, drive sleeve 410, push rod 411, guide push plate 412 and locking plate 413, so that the locking plate 413 moves out of the locking groove 414, releases the limit, and facilitates the flipping of the position between the outer sealing frame 407, the folding side plate 2 and the back plate 1, so that it fits against one end of the back plate 1. And through the cooperation of the tension spring 404 contraction, the reset slide plate 403, the rotating support 406, the connecting pull plate 405 and the outer sealing frame 407 are pulled, forcing the positioning pin 418 to be embedded in the insertion hole, ensuring the effect after folding; Next, the lifting screw 302 is reversed to make the lifting column 303 slide down. Then, through the cooperation of the support arm 304, the sliding push plate 306, the guide rod 305, the sliding plate 307, the rotating frame 308 and the bonding plate 309, the folding side plate 2 is pulled to rotate and fold. At the same time, through the cooperation of the bonding plate 309, the side partition 315 is pushed to slide along the central partition 318, forcing the multi-section telescopic sleeve 317 to retract, so that the two folding side plates 2 can be aligned and folded. At the same time, the side partition 315 and the central partition 318 are folded between the folding side plate 2 and the back plate 1, reducing the thickness after folding, making it easier to stack and store, improving the convenience of transportation, and making it easier to transport the distribution box to a suitable location for assembly, ensuring the convenience of installation. Finally, after folding, rotating the bidirectional screw 320 causes the two locking pin plates 321 to move synchronously in opposite directions, forcing the locking pin plates 321 to engage with the limiting buckles 330 on the folding side plate 2, thereby limiting the folding side plate 2 after folding, preventing it from loosening and falling apart during transportation, and improving convenience.
