[0043] Then the staff drives the rotating part 220 to rotate. When the rotating part 220 rotates, the rotating part 220 will drive the screw rod 219 to rotate synchronously. The screw rod 219 will drive the sliding block 218 to move horizontally. The sliding block 218 will drive the connecting seat 217 to move horizontally. The connecting seat 217 will drive the pulling rod 216 to gradually change from a horizontal state to an inclined state. The pulling rod 216 will pull the connecting shaft 215. The connecting shaft 215 will drive the sliding plates 211 on both sides to slide horizontally.

The first sliding member 27 moves through the sliding groove 1, so that the first sliding member 27 is slidably connected to the support frame 21, and the side of the connecting plate 28 away from the first sliding member 27 is fixedly connected to the top of the vertical cross plate 29. The connecting bottom plate 210 is fixedly connected to the end of the vertical cross plate 29 away from the connecting plate 28, so that the connecting plate 28 is fixedly connected to the connecting bottom plate 210 through the vertical cross plate 29. The top of the connecting plate 28 is penetrated with a sliding groove 2, and the sliding plate 211 moves through the sliding groove.

[0045] At this time, the connecting base plate 210 can be slid horizontally according to the needs of the experiment to cooperate with the experiment. When the position of the connecting base plate 210 needs to be fixed, it is only necessary to continue to rotate the rotating member 220 so that the sliding plate 211 continues to move horizontally relative to each other, so that the holes of the connecting strips 213 on both sides are aligned, and then the screws 214 are passed through the two connecting strips 213 in turn to fix the two sides together. At this time, the roller 222 located in the slide rail 223 is squeezed by the relative pressure of the sliding plate 211 and the first sliding member 27 and can no longer rotate, thereby completing the fixation of the connecting base plate 210.

[0046] Reference Figure 4 - Figure 7The end of the sliding plate 211 away from the clamping plate 212 is fixedly connected to the top of the connecting shaft 215, and the top of the pulling rod 216 close to the connecting shaft 215 is provided with a second circular hole, and the outer wall of the connecting shaft 215 is movable through the second circular hole, so that the pulling rod 216 is rotatably connected to the connecting shaft 215, and the top of the pulling rod 216 away from the connecting shaft 215 is provided with a third circular hole, and the connecting seat 217 is movable through the third circular hole, so that the connecting seat 217 is rotatably connected to the pulling rod 216, and the side of the connecting seat 217 away from the pulling rod 216 is fixedly connected to the end of the sliding block 218 close to the connecting seat 217, and the side wall of the sliding block 218 is provided with an internal threaded hole three, and the screw rod 219 is threaded through the internal threaded hole three, so that the screw rod 219 is threadedly connected to the sliding block 218, vertically There is a circular hole four on the side wall of the horizontal plate 29, and the two ends of the screw rod 219 close to the vertical horizontal plate 29 and the side wall of the vertical horizontal plate 29 are movably passed through the circular hole four, so that the screw rod 219 is rotatably connected to the vertical horizontal plate 29, and one end of the screw rod 219 close to the rotating member 220 is fixedly connected to the rotating member 220, and the side of the sliding plate 211 close to the first sliding member 27 is fixedly connected to the end of the connecting piece 221 close to the sliding plate 211, and a rotating shaft is fixedly connected between the two connecting pieces 221, and the roller 222 is movably passed through the rotating shaft, so that the roller 222 is rotatably connected to the connecting piece 221, and the slide rail 223 is horizontally opened on the side wall of the first sliding member 27, and the slide rail 223 is slidably connected to the side of the roller 222 close to the first sliding member 27, and the two ends of the second sliding member 224 are fixedly connected to the inner wall of the support frame 21.

[0047] When the height needs to be raised, the staff rotates the rotating cylinder 24, and the rotating cylinder 24 will move vertically, thereby driving the sliding cylinder 25 to move vertically, and the sliding cylinder 25 will drive the lifting member 26 to move vertically, and the lifting member 26 will drive the first sliding member 27 to move vertically, thereby completing the lifting of the entire mechanism, thereby increasing the vertical height of the connecting base plate 210, making the equipment operation more flexible. If the equipment needs to be set horizontally, it is only necessary to turn the connecting plate 28 to a vertical state and then rotate the rotating member 220 so that the connecting plate 28 is clamped on the side of the second sliding member 224, so as to facilitate switching according to the needs of the experiment.

[0048] The implementation principle of a modular safety cabinet in the embodiment of the present application is as follows:

[0049] The staff drives the rotating member 220 to rotate, and the rotating member 220 will drive the connecting seat 217 to move horizontally. The connecting seat 217 will drive the pulling rod 216 to gradually turn from a horizontal state to an inclined state. The pulling rod 216 will drive the sliding plates 211 on both sides to slide horizontally, and the clamping plate 212 will drive the roller 222 to embed into the slide rail 223, so that the connecting base plate 210 is suspended on the top of the first sliding member 27. When the position of the connecting base plate 210 needs to be fixed, the rotating member 220 is continued to be rotated, so that the sliding plate 211 continues to move horizontally relative to each other, so that the holes of the connecting strips 213 on both sides are aligned, and the screws 214 are rotated through in sequence. The two connecting bars 213 fix the two sides together, and the roller 222 is squeezed by the sliding plate 211 and the first sliding member 27 so that it can no longer rotate, thereby completing the fixation. When the height needs to be raised, the staff rotates the rotating cylinder 24, and the rotating cylinder 24 will drive the first sliding member 27 to move vertically, thereby completing the lifting of the entire mechanism, thereby increasing the vertical height of the connecting base plate 210, making the equipment operation more flexible. If the equipment needs to be set horizontally, just turn the connecting plate 28 to a vertical state, and then rotate the rotating member 220 so that the connecting plate 28 is clamped on the side of the second sliding member 224.
