The hinge 5 includes a pivot connecting part 6 and a door panel connecting part 7. The outer surfaces of the pivot boss 2 and the pivot connecting part 6 are flush with the outline of the column 1, forming a continuous decorative line visually.

[0043] Understandably, this hinge 5 is a free hinge, without springs or damping, and cannot be stopped arbitrarily (stopping arbitrarily means stopping at a fixed angle). Therefore, it can be opened and closed an unlimited number of times without damaging the lifespan of hinge 5, making it more durable.

[0044] Specifically, column 1 is provided with a slot for connecting with the plate.

[0045] The number of mounting slots 4 can be two or more, and the two or more mounting slots 4 are spaced apart in the vertical direction. The number of hinges 5 is equal to the number of mounting slots 4, and they are set in a one-to-one correspondence.

[0046] Specifically, the bearing boss 2 is integrally formed on the front side of the column 1. The pivot connection part 6 and the door panel connection part 7 are integrally formed structures.

One end of the side panel 11 is connected to the rear side post 14 through the side panel slot, and the other end is snapped into the front side post 16. One end of the center vertical panel 12 is connected to the rear center post 15 through the center vertical panel slot, and the other end is snapped into the front center post 17. The top panel 9 and the bottom panel 10 are respectively fixed to the upper and lower ends of the rear side post 14, the rear center post 15, the front post 16, and the front center post 17 with screws. The door panel 13 is fixed to the door panel connecting part 7 of the door body connecting structure.

[0049] Specifically, the cabinet body can be made of aluminum alloy, which is lighter and more durable. The outer surface of the cabinet body can be coated with an anti-corrosion coating to further improve the cabinet's durability.

[0050] In practice, first insert the back panel 8 into the back panel slots of the two rear side posts 14, and then use screws (from the back of the back panel 8) to fix the rear center post 15 to the back panel 8.
