Technical Field

[0001] This utility model relates to the field of experimental platform technology, specifically an adjustable height experimental platform. Background Technology

[0002] Laboratory benches are workbenches used by hospitals, schools, chemical plants, research institutes and other enterprises and institutions for conducting experiments. They are classified according to their placement as: central laboratory benches, side laboratory benches, and corner benches; and according to their material as: all-steel laboratory benches, steel-wood laboratory benches, all-wood laboratory benches, PP laboratory benches. There are also some tall cabinets: fume hoods, medicine cabinets, glassware cabinets, gas cylinder cabinets, explosion-proof cabinets, glass slide cabinets, etc.

[0003] An experimental table is a workbench used for experimental testing and storage of instruments. However, existing experimental tables do not have the function of adjusting the height, which cannot meet the needs of experimental personnel of different heights, reduces the comfort of the experimental table, and leads to frequent accidents during the experiment. Therefore, we propose an adjustable height experimental table. Utility Model Content

[0008] Furthermore, the pulling assembly includes a fixing strip and a handle. The front sides of the two front racks are fixed with fixing strips, and a handle is fixed between the two fixing strips. The pulling assembly facilitates the user to pull the two front racks to move them.

[0009] Furthermore, the pressing assembly includes a U-shaped rod, a limiting plate, and a first spring. A sliding hole is provided on the upper side of the fixing strip, and a U-shaped rod is slidably connected inside the two sliding holes. Two corresponding limiting plates are fixed to the lower end of the U-shaped rod, and two corresponding first springs are sleeved on the surface of the U-shaped rod. The lower end of the first spring is fixed to the upper end of the corresponding limiting plate, and the upper end of the first spring is fixed to the lower side of the corresponding fixing strip. The pressing assembly drives the two pull ropes to move.

[0010] Furthermore, the fixing assembly includes a mounting groove, a sliding plate, a locking head, a second spring, a pull rope, and a locking slot. The mounting groove is located on the rear side of the fixing strip, and the sliding plate is slidably connected inside the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable height experimental platform has the following advantages:

[0013] By setting up a pressing component, users can press the U-shaped rod downwards to pull the two ropes to move the device as needed. The movement of the two ropes causes the two clips to separate from their corresponding slots. After separation, pressing the U-shaped rod further compresses the handle downwards, causing the two fixing bars to move upwards and move the two front racks downwards. This causes the two gear rings to rotate, moving the two rear racks upwards. In this way, the height of the platform can be adjusted, which is extremely convenient. Attached Figure Description

The pressing component 4 includes a U-shaped rod 41, a limiting plate 42, and a first spring 43. Sliding holes are opened on the upper side of the fixing strips 31, and the inner surfaces of the two sliding holes... A U-shaped rod 41 is slidably connected to the fixing component 31. Two corresponding limiting discs 42 are fixed to the lower end of the U-shaped rod 41. Two corresponding first springs 43 are sleeved on the surface of the U-shaped rod 41.

A mounting groove 51 is provided on the rear side of the fixing strip 31. A sliding plate 52 is slidably connected inside the mounting groove 51. A locking head 53 is fixed to the rear end of the sliding plate 52, and a second spring 54 is sleeved on the surface of the locking head 53. The front end of the second spring 54 is fixed to the rear end of the slide plate 52, and the rear end of the second spring 54 is fixed to the front side of the corresponding support plate 22.

[0024] The working principle of the adjustable height experimental platform provided by this utility model is as follows: During use, the user can press the U-shaped rod 41 downwards to pull the two pull ropes 55 to move it as needed. The movement of the two pull ropes 55 causes the two locking heads 53 to separate from the corresponding two locking slots 56. After separation, continue to press the U-shaped rod 41 to squeeze the handle 32 downwards, causing the two fixing bars 31 to move upwards and drive the two front racks 25 downwards, thereby causing the two gear rings 26 to rotate and drive the two rear racks 25 upwards. In this case, the height of the platform 1 can be adjusted. After the height of the platform 1 is adjusted, release the U-shaped rod 41. At this time, the U-shaped rod 41 will return to its original position under the action of the two first springs 43. At the same time, the two locking heads 53 will enter the interior of the corresponding two locking slots 56 under the action of the two second springs 54. In this case, the two fixing bars 31 can be fixed, thereby fixing the two front racks 25. In this case, the platform 1 can be fixed, and after fixing, it is convenient for the user to conduct experiments.
