The experimental lifting platform of the device embeds the shelf on the experimental table, and in the process of manually adjusting the lifting of the experimental table, the shelf is driven to extend or retract into the experimental table. However, in the actual operation of the experiment, if the experimental table is raised to the highest point, the scissor-type mechanism will be located on one side of the experimental table, and the shelf is supported on one side, resulting in a center offset. If a heavier experimental object is placed on the shelf, there is a risk of the shelf overturning.

[0007] Furthermore, the pressing assembly consists of a connecting block, an air collecting pipe, a piston, a threaded rod and a limit rod. The connecting block is fixed to the side of the base, the air collecting pipe is connected to the connecting block and is connected to the lifting cylinder, the inside of the air collecting pipe is connected to the piston, the threaded rod is connected to the air collecting pipe by threads, the lower end of the threaded rod is rotatably connected to the piston, and the piston is fixed with a limit rod that is slidably connected to the air collecting pipe.

DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment: A lifting platform for chemical laboratory, such as Figure 1-Figure 4 As shown, it includes a base 1, a lifting cylinder 2, a pressing component and a placing table 3. The lifting cylinder 2 is installed on the base 1. The pressure of the lifting cylinder 2 is increased or decreased by the pressing component to control its height. The placing table 3 is connected to the telescopic end of the lifting cylinder 2, and also includes a clamping mechanism. The clamping mechanism is arranged on the placing table 3. The clamping mechanism includes a fixed plate 9, a movable plate 10 and a two-way adjustment rod 12. The placing table 3 is fixedly connected to the side of the fixing plate 9. The placing table 3 is provided with a slide rail 11. The movable plates 10 are arranged opposite to each other and are slidably connected to the placing table 3 through the slide rail 11. The movable plate 10 can clamp and fix the experimental equipment located on the placing table 3. The two-way adjustment rod 12 is provided with symmetrical threads. The two-way adjustment rod 12 is threadedly connected to the movable plates 10 on both sides. After rotating the two-way adjustment rod 12, the movable plate 10 can be driven to move synchronously towards or away from each other, thereby achieving the effect of clamping and releasing the clamping.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the pressing assembly consists of a connecting block 4, an air collecting pipe 5, a piston 6, a threaded rod 7 and a limiting rod 8. The connecting block 4 is fixed to the side of the base 1, the air collecting pipe 5 is connected to the connecting block 4 and is connected to the lifting cylinder 2, the piston 6 is connected to the inside of the air collecting pipe 5, the threaded rod 7 is threadedly connected to the air collecting pipe 5, the lower end of the threaded rod 7 is rotatably connected to the piston 6, and the piston 6 is fixed with a limiting rod 8 that is slidably connected to the air collecting pipe 5.

[0023] like Figure 1 As shown, a foam pad 13 is also included, and the foam pad 13 is arranged on the opposite side of the movable board 10.

[0024] like Figure 1 As shown, it also includes an anti-skid pad 14, a handle 15 and an adjustable foot 16. A handwheel is provided at the upper end of the threaded rod 7, the anti-skid pad 14 is sleeved on the upper end of the threaded rod 7, the handle 15 is fixedly connected to the side of the base 1, and the adjustable foot 16 is provided at the bottom of the base 1.

[0025] Working principle: After placing the experimental equipment on the placement table 3, rotate the two-way adjustment rod 12 to drive the movable plate 10 to move in opposite directions. The movable plate 10 can clamp and fix the experimental equipment to improve its stability, and then rotate the threaded rod 7. Since the threaded rod 7 is connected to the air collecting pipe 5 through threads, the threaded rod 7 can move downward after rotation. At the same time, the piston 6 at the lower end of the threaded rod 7 will move downward synchronously, and the piston 6 will press the air in the air collecting pipe 5 into the lifting cylinder 2, which will lift the lifting cylinder 2 upward, thereby achieving the effect of adjusting the height of the placement table 3.
