Description

Technical Field

[0001] The invention relates to the field of automatic shaking devices, in particular to a novel automatic shaking device for a conical bottle. Background Art

[0002] The conical flask is a common glass instrument in chemical laboratories. It was invented by German chemist Richard Orlenmayer in 1861. The conical flask is a titration reactor made of hard glass with a triangular longitudinal section. It has a small mouth and a large bottom, which is conducive to the full reaction and the liquid is not easy to splash out during the titration process. The container can be heated in a water bath or an electric furnace; in chemical experiments, it is often necessary to shake the conical flask. The existing shaking and mixing device has certain difficulties in fixing the conical flask due to the special shape of the conical flask. Secondly, a few shaking devices cannot drip the titration solution into the bottle smoothly during shaking. Since then, the shaking amplitude of the conical flask cannot be adjusted. For this reason, we propose a new automatic shaking device for conical flasks. Summary of the invention

A supporting base is arranged on the rotating base, and the supporting base is movably connected to the rotating base through a magnetic steel, so that the eccentricity can be arbitrarily adjusted according to actual needs, thereby making the conical flask form different shaking amplitudes to meet the requirements. An adjusting bolt is arranged on one side of the movable clamp, and the movable clamp is movably connected to the supporting base through a rubber connecting belt, which is conducive to installing the conical flask in the fixed clamp and the movable clamp, and can fix the conical flask.
