When the bottom plate 4 contacts the ground, the cabinet body 1 will be lifted up, so that the cabinet body 1 can be suspended in the air to prevent the accumulated water on the ground from seeping into the cabinet body 1. The cabinet 1 is provided with a rainproof mechanism 5; wherein the rainproof mechanism 5 comprises: a top cover 51, a slide groove 52, a limit rod 53, a rotating shaft 54, a wind cover 55, a drain hole 56, a counterweight rod 57, an eccentric wheel 58, a slide frame 59, a push-pull rod 510, a baffle 511, a positioning rod 512, an L rod 513, a limit groove 514 and a limit inclined rod 515, the inner wall of the top cover 51 is fixedly installed with the limit rod 53, the outer wall of the cabinet 1 is rotatably connected with the rotating shaft 54, and the outer wall of the rotating shaft 54 ​​is fixedly installed with the wind cover 55 When it rains and a strong wind blows at the same time, the wind blows the wind shield 55, causing the wind shield 55 to gradually tilt. At the same time, the wind shield 55 drives the rotating shaft 54 ​​to rotate on the outer wall of the cabinet 1. The wind shield 55 is provided with a drainage hole 56. When rain drops on the inside of the wind shield 55, it will be discharged from the wind shield 55 through the drainage hole 56, thereby preventing rain from accumulating inside the wind shield 55.

At the same time, the top cover 51 can be used to block the falling raindrops to prevent the raindrops from impacting the surface of the cabinet 1 and causing water seepage inside the cabinet 1. When it rains and a strong wind blows, the wind blows the wind cover 55 to make the wind cover 55 gradually tilted. At the same time, the wind cover 55 will drive the rotating shaft 54 ​​to rotate on the outer wall of the cabinet 1. When the rotating shaft 54 ​​rotates, it will drive the eccentric wheel 58 to push the sliding frame 59, so that the sliding frame 59 slides on the outer wall of the cabinet 1. When the sliding frame 59 slides on the outside of the cabinet 1, it will drive the push-pull rod 510 to move in contact with the inner wall of the slide groove 52. At the same time, the push-pull rod 5 10 will push the top cover 51, so that the top cover 51 rotates and gradually tilts on the top of the cabinet 1.
