[0019] The clamping assembly includes a clamping groove 55 and a clamping block 56, the side wall of the rotating groove 5 is provided with three movable grooves 52, the three movable grooves 52 are respectively provided on the upper and lower ends of the rotating groove 5 and the side away from the installation pivot 2, the clamping groove 55 is provided on the side close to the upper door plate 11 and the lower door plate 12, and the position is aligned with the movable groove 52, the clamping block 56 is slidingly connected in the movable groove 52, the outside of the clamping block 56 extends out of the movable groove 52 and is inserted in the clamping groove 55, a flat notch 57 is provided on the rotating plate 51, a telescopic block 53 is slidingly connected on the inside of the movable groove 52, the outside of the telescopic block 53 is fixed with the clamping block 56, the inside of the telescopic block 53 is of a circular arc structure and abuts against the outside wall of the rotating plate 51, and a return spring 54 is fixed between the telescopic block 53 and the inside wall of the movable groove 52.

[0020] The switch assembly includes a lock hole 43 and a telescopic groove 45, the lock hole 43 is provided at the center position of the lock cylinder 42, a billiard ball 44 is single slidingly connected on the lock hole 43, three telescopic grooves 45 are provided on the inside of the shell 41 and at the positions corresponding to the billiard ball 44, a top block 46 is slidingly connected in the telescopic groove 45, the bottom of the top block 46 abuts against the upper end of the billiard ball 44, a ejection spring 47 is fixed between the upper end of the top block 46 and the side wall of the telescopic groove 45, and the three telescopic grooves 45 are separately provided on the upper and lower ends of the shell 41 and the side away from the installation pivot 2.

[0021] Working principle: by rotating the rotating plate 51, the position of the flat notch 57 on the rotating plate 51 can be changed. When the flat notch 57 is rotated to align with the upper movable groove 52, the upper reset spring 54 pushes the telescopic block 53 downward, so that the bottom of the telescopic block 53 abuts against the side wall of the flat notch 57. At this time, the clamping block 56 is driven downward, so that the end of the clamping block 56 is pulled out of the clamping groove 55, thereby releasing the fixing between the connecting door plate 13 and the upper door plate 11, so that the upper door plate 11 can be opened independently. Similarly, when the flat notch 57 is rotated downward, the lower door plate 12 can be opened independently. When the flat notch 57 is rotated to the side away from the mounting shaft 2, the corresponding clamping block 56 is retracted, so that the fixing between the connecting door plate 13 and the switch cabinet is released. At this time, the upper door plate 11 and the lower door plate 12 are fixed with the connecting door plate 13, so that the switch cabinet door plate 1 can be opened as a whole, thereby increasing the flexibility and convenience of use. In this process, by inserting the key into the lock hole 43, the marble 44 is lifted, thereby pushing the top block 46 into the telescopic groove 45. Under the compression of the ejection spring 47, the connection between the marble 44 and the top block 46 is aligned with the connection between the lock cylinder 42 and the shell 41, thereby enabling the lock cylinder 42 to rotate freely, and finally enabling the rotating plate 51 to rotate freely. When the key is pulled out at the specified position, the reset of the ejection spring 47 can push the top block 46 out of the telescopic groove 45 and be located at the connection between the lock cylinder 42 and the shell 41, thereby fixing the lock cylinder 42.
