[0028] In some embodiments, the above-mentioned characteristic rotating assembly can be used as follows Figure 1 and Figure 5 See the structure shown. Figure 1 and Figure 5, the rotating assembly includes a fixed rod 51 and two connecting rods 52. The fixed rod 51 is arranged along the rotation axis of the rotating assembly. The two connecting rods 52 are respectively located on both sides of the test box 1 along the length direction of the fixed rod 51, and the connecting rod 52 is fixedly connected to the fixed rod 51. The connecting rod 52 is used to be connected to the test box 1 around the horizontal axis. Among them, the test column 6 is fixed on the fixed rod 51.

The rotating connection between the rotating assembly and the test box 1 is realized by the rotation connection between the connecting rod 52 and the test box 1. When the rotating assembly rotates, the fixed rod 51 rotates around the test box 1, so that the test column 6 can be driven to reach directly above or directly below the test box 1.
[0029] In some embodiments, see Figure 2 and Figure 6 The environmental simulation device for concrete further includes two fixed shafts 8. The two fixed shafts 8 are respectively located on both sides of the test box 1 relative to the two connecting rods 52. The fixed shafts 8 are arranged along the rotation axis of the rotating assembly and are fixedly connected to the test box 1. The fixed shafts 8 penetrate the connecting rods 52 on the same side. The connecting rods 52 are rotatably connected to the test box 1 by rotating with the fixed shafts 8 on the same side.
[0030] In some embodiments, see Figure 2 and Figure 6 The side of the fixed shaft 8 has a first stopper 81 protruding outward, and the first stopper 81 is located between the test box 1 and the connecting rod 52 on the same side. The first stopper 81 stops the connecting rod 52 from contacting the test box 1, so that friction damage to the test box 1 can be avoided during the rotation of the connecting rod 52.
[0031] In some embodiments, see Figure 2 , Figure 5 and Figure 6 , the side of the fixed shaft 8 has a second limit portion 82 protruding outward, the second limit portion 82 is located on the side of the connecting rod 52 on the same side away from the first limit portion 81, a first threaded hole 521 is provided on the connecting rod 52, and the locking member 7 is a bolt and there are two of them. The screws of the two locking members 7 are respectively inserted into the two second limit portions 82. When the rotating assembly is in the first position, the screws of the two locking members 7 are respectively threaded into the two first threaded holes 521. At this time, the fixed shaft 8 fixed on the test box 1 can limit the rotation of the connecting rod 52 through the locking member 7, thereby locking the rotating assembly with the test box 1. When the screw of the locking member 7 exits the first threaded hole 521, the rotating assembly can continue to rotate. In this embodiment, the axis centerline of the first threaded hole 521 is parallel to the axis centerline of the fixed shaft 8.
[0032] In some embodiments, see Figure 2 , Figure 5 and Figure 6 , a second threaded hole 522 is provided on the connecting rod 52. When the rotating assembly is in the second position, the screws of the two locking members 7 are respectively threadedly connected in the two second threaded holes 522. At this time, the fixed shaft 8 fixed on the test box 1 can limit the rotation of the connecting rod 52 through the locking member 7, thereby locking the rotating assembly with the test box 1. When the screw of the locking member 7 exits the second threaded hole 522, the rotating assembly can continue to rotate. In this embodiment, the axis of the second threaded hole 522 is parallel to the axis of the fixed shaft 8, and the second threaded hole 522 and the first threaded hole 521 are symmetrically arranged on both sides of the axis of the fixed shaft 8.
[0033] In some embodiments, see Figure 4 The bracket 2 has a horizontally arranged first fixing plate 21, and the first fixing plate 21 is located below the opening and closing plate 3. The environmental simulation device for concrete further includes a sliding shaft 9. There are at least two sliding shafts 9, and the sliding shafts 9 are arranged vertically. The sliding shafts 9 are fixedly connected to the opening and closing plate 3 and slide through the first fixing plate 21. The sliding connection between the opening and closing plate 3 and the bracket 2 is achieved by the sliding cooperation between the first fixing plate 21 and the sliding shafts 9.
[0034] In some embodiments, see Figure 1 and Figure 3 The bracket 2 has a second fixing plate 22 arranged horizontally, and the second fixing plate 22 is located below the first fixing plate 21. The driving assembly 4 is fixed on the second fixing plate 22. The first fixing plate 21 is provided with a through hole 211 for the piston rod 41 of the driving assembly 4 to pass through, thereby achieving the fixing of the driving assembly 4 on the bracket 2.
[0035] In some embodiments, see Figure 4 The environmental simulation device for concrete further comprises a rectangular frame 10. The rectangular frame 10 is horizontally arranged and fixedly arranged on the bottom surface of the opening and closing plate 3. The rectangular frame 10 can increase the strength of the opening and closing plate 3, thereby preventing the opening and closing plate 3 from deforming.
[0036] In some embodiments, the driving assembly 4 uses a hydraulic cylinder or a jack, which can be selected according to actual needs.
