[0014] like Figure 1-Figure 3As shown, a sample rotating table structure of a rain test box comprises an inner liner 1 of the rain test box, a sample table 2 and a connecting pipe 3. The connecting pipe 3 longitudinally penetrates the bottom plate of the inner liner 1 and is rotatably connected to the bottom plate of the inner liner 1 through a sealing bearing 4. A sliding sleeve 5 is provided on the connecting pipe 3. A slider 51 is fixedly connected to the inner wall of the sliding sleeve 5. A longitudinal slide groove 31 is transparently provided on the circumferential surface of the connecting pipe 3. The slider 51 is slidably fitted in the slide groove 31, and the slider 51 extends to the inside of the connecting pipe 3 through the slide groove 31. The top screw of the connecting pipe 3 The sample stage 2 is circular, and a hinge block is provided at the bottom center of the sample stage 2. The sample stage 2 is hinged in the hinge seat at the top of the sealing cover 6 through the hinge block. A connecting rod 7 is hinged between the bottom surface of the sample stage 2 and the outer wall of the sliding sleeve 5 at a position of half of its own radius. The connecting tube 3 is sequentially sleeved with a first telescopic tube 8 and a second telescopic tube 9 from top to bottom. Both the first telescopic tube 8 and the second telescopic tube 9 are corrugated hoses. The two ends of the first telescopic tube 8 are respectively sealed and fixed. The second telescopic tube 9 is sleeved on the sealing cover 6 and the sliding sleeve 5, and the two ends of the second telescopic tube 9 are respectively and sealedly fixedly sleeved on the sliding sleeve 5 and the bottom of the connecting tube 3.
