[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: an adjustable experimental platform for particle analysis experiments, including an operating table 1, a slide groove 2 is opened inside the operating table 1, a slide 3 is arranged inside the operating table 1, a connecting frame 4 is fixedly connected to the bottom of the slide 3, a rotating rod 5 is rotatably connected to one side of the connecting frame 4, a rotating column 6 is rotatably connected to one side of the rotating rod 5, a connecting block 7 is rotatably connected to one end of the rotating column 6, a fixed frame 8 is fixedly connected to the bottom of the slide 3, a rotating block 9 is rotatably connected to the inside of the fixed frame 8, a spring 10 is fixedly connected to one side of the connecting block 7, one end of the spring 10 is fixedly connected to one side of the rotating block 9, a bracket 11 is rotatably connected to one side of the slide 3, a connecting rod 12 is rotatably connected to one side of the bracket 11, and one side of the connecting rod 12 is fixedly connected to the outer wall of the rotating column 6, a limiting component is arranged on one side of the slide 3, the limiting component includes a limiting plate 13, one side of the limiting plate 13 is fixedly connected to one side of the slide 3, and a storage box 24 is arranged inside the operating table 1.

[0025] Specifically, when using the experimental platform, the slide 3 can be moved to the outside of the operating table 1 by pulling the slide 3. At this time, the slide 3 is forced to slide inside the slide groove 2. When the slide 3 moves out of the operating table 1, the rotating rod 5 begins to rotate under force, driving the rotating column 6 connected to it on one side to rotate, and then pushing the connecting block 7 to rotate. The movement of the connecting block 7 triggers the contraction of the spring 10 fixedly connected on one side, which provides power for the expansion of the experimental platform. After the slide 3 stops moving, the spring 10 releases the stored energy, resets the connecting block 7 and the rotating rod 5, and clamps the connecting block 7 on the outer wall of the operating table 1. At the same time, the movement of the rotating column 6 also causes the connecting rod 12 fixedly connected to the outer wall to rotate, thereby driving the bracket 11 connected to one side of the connecting rod 12 to rotate. When the bracket 11 rotates to a certain position, it is blocked by the limit plate 13 to ensure that it stands firmly on the ground, thereby fixing the experimental platform and achieving the effect that the experimental platform can be expanded.

[0026] Reference Figure 1 and Figure 4 A fixing rod 23 is fixedly connected to the top of the operating table 1, a fixing frame 14 is fixedly connected inside the fixing rod 23, a turntable 15 is rotatably connected to the upper surface of the fixing frame 14, a handle 16 is fixedly connected to the outer wall of the turntable 15, a limiting groove 17 is provided inside the turntable 15, a connecting plate 18 is rotatably connected to the top of the turntable 15, a limiting column 19 is arranged inside the turntable 15, and the limiting column 19 is slidably connected inside the limiting groove 17.

[0027] Specifically, when placing the experimental container, first place the container on the surface of the connecting plate 18 to ensure that it is stable. Then, by turning the handle 16, the handle 16 is driven by force to drive the rotating disk 15 fixed at one end to rotate on the top of the fixing frame 14. A limiting groove 17 is provided in the rotating disk 15. Through the limiting of the limiting groove 17, the limiting column 19 is forced to slide in it, achieving the limiting effect.

[0028] Reference Figure 4 and Figure 5 A second limiting groove 20 is provided inside the connecting plate 18 , a slider 21 is fixedly connected to the top of the limiting column 19 , a side wall of the slider 21 is slidably connected inside the second limiting groove 20 , and a clamping block 22 is fixedly connected to the top of the slider 21 .

[0029] Specifically, the limiting column 19 is then forced to drive the slider 21 fixedly connected at the top to slide inside the limiting groove 20, and the movement of the slider 21 drives the clamping block 22 fixedly connected at the top to move. The movement of the clamping block 22 clamps the outer wall of the container to ensure that the container is firmly fixed on the experimental platform, so that the container will not move or shake during the experiment, thereby achieving the effect of fixing the container.

[0030] Working principle: When using the experimental platform, the slide 3 can be moved to the outside of the operating table 1 by pulling the slide 3. At this time, the slide 3 is forced to slide inside the slide groove 2. When moving out of the operating table 1, the rotating rod 5 is forced to rotate, and at the same time, the rotating rod 5 drives the rotating column 6 rotatably connected on one side to rotate. The rotating column 6 is forced to drive the connecting block 7 rotatably connected at one end to rotate. The connecting block 7 is forced to drive the spring 10 fixedly connected on one side to contract. Then, when the slide 3 stops moving, the spring 10 unloads the force and rebounds, thereby driving the connecting block 7 and the rotating rod 5 to reset, so that the connecting block 7 is stuck on the outer wall of the operating table 1. At the same time, the rotating column 6 is also forced to drive the connecting rod 12 fixedly connected to the outer wall to rotate, and the connecting rod 12 is forced to drive the support 12 rotatably connected on one side The frame 11 rotates, and when the frame 11 rotates to a certain position, it is blocked by the limit plate 13, so that the frame 11 stands on the ground and is fixed, thereby achieving the effect that the experimental platform can be expanded. When placing the experimental container, first place the container on the upper surface of the connecting plate 18, and then rotate the handle 16. The handle 16 is driven by the force to drive the turntable 15 fixed at one end to rotate on the top of the fixed frame 14, and the turntable 15 drives the limit column 19 to slide inside it through the limit groove 17 opened inside. The limit column 19 is driven by the force to drive the slider 21 fixed at the top to slide inside the limit groove 20, and the slider 21 is driven by the force to drive the clamping block 22 fixed at the top to move, and the outer wall of the container is clamped by the movement of the clamping block 22, thereby achieving the effect of fixing the container.
