[0030] Working principle:
[0031] When using this utility model, the user should first grasp the pull rod 9 located on the front side of the operation panel 3 and pull the pull rod 9 to pull out the isolation plate 6 fixed to the pull rod 9 from the sliding groove 7 opened on the front side of the operation panel 3. After the isolation plate 6 is partially pulled out, the user can flip the isolation plate 6 upward by pulling the pull rod 9. One side of the isolation plate 6 will be close to the front side of the baffle 1, and the baffle 1 is fixed to the top of the operation panel 3. A rotating sleeve 14 is fixedly connected to the front side of the baffle 1, and a rotating rod 15 is rotatably connected to the rotating sleeve 14. A sliding block 13 is fixedly connected to one end of the rotating rod 15. The vertical section of the sliding block 13 is perpendicular to the opening. The vertical cross-section of the sliding groove 10 on the isolation plate 6 is aligned with that of the sliding block 13 located on the front side of the baffle 1. Rotating the sliding block 13 causes the rotating rod 15 fixed to one side of the sliding block 13 to rotate synchronously. This, in turn, causes the torsion spring 16, located inside the rotating sleeve 14 and fixed at both ends to one side of the rotating rod 15 and the inner side wall of the rotating sleeve 14, to twist. After rotating 90 degrees, the sliding block 13 aligns with the sliding groove 10 on the isolation plate 6. By aligning one side of the isolation plate 6 with the front side of the baffle 1, the sliding block 13 moves along the sliding groove 10 to the isolation plate 6. On the other side of plate 6, release the clamp on the sliding block. At this time, the sliding block 13 will reset under the rebound action of the torsion spring 16. After resetting, the sliding block 13 will be perpendicular to the sliding groove 10. Therefore, the contact between the sliding block 13 and the sliding groove 10 can firmly fix the isolation plate 6. At this time, the user can insert their hand, which is wearing protective gear, into the insertion hole 11 opened on the isolation plate 6. In this way, the user can freely conduct experiments on the operating panel 3. The isolation plate 6 can isolate the chemical experiment in case of user error or explosion. Plate 6 blocks splashed liquid or fragments to prevent injury to the user. Below the isolation plate 6, a connecting plate 12 is rotatably connected. There are multiple connecting plates 12, and the user can pull out different numbers of connecting plates 12 according to their own height to adapt to different heights. One of the connecting plates 12 has a movable block 17 fixed on both sides. The movable block 17 slides with the movable groove 8 set on the left and right sides of the slide 7. A drawer 4 slides on the front side of the control plate 3. A handle 5 is fixed on the front side of the drawer 4 for easy pulling by the user. A support leg 2 is fixed at the bottom of the control plate 3 to support the entire device.
[0032] In this utility model, the torsion spring 16, handle 5, baffle 1 and other components are all existing technologies, and their working principle is the same as that of similar products on the market, so they will not be described in detail here.
[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
