Fixing frame for distillation flask

Abstract

The invention discloses a fixing frame for a distillation flask, which belongs to the field of laboratory equipment. The fixing frame for the distillation flask comprises a bracket and a mounting table, wherein the mounting table is slidably connected to the bracket; a first groove, a second groove and a third groove are formed in the mounting table; a lifting rod is connected into the first groove in a sliding manner; a button is connected to the top of the lifting rod; the bottom of the lifting rod is rotationally connected with a tray through a first hinge; a positioning hole is formed in the end, away from the mounting table, of the tray; a first rotating shaft is rotationally connected into the second groove; the tray is rotatably connected to the first rotating shaft, a clamping device is slidably connected into the third groove, the clamping device is connected with the lifting rod through a pull rope, symmetrical elastic clamping plates are connected to the end, away from the mounting table, of the clamping device, a roller is rotatably connected into the third groove, and the roller is matched with the clamping device and the lifting rod. The gravity of the flask is converted into a bottleneck clamping force by utilizing a lever principle, so that the flask is fixed.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a fixing frame for a distillation flask. Background technique [0002] A flask is a glass vessel with a neck used in the laboratory. It is used to hold liquid substances. It is called a flask because it can withstand a certain amount of heat; flasks usually have a flat bottom and a round bottom. The flat bottom is called a flat bottom flask, and the round bottom is called a flask. Round bottom flask; the flask is usually used with a condenser tube and a liquid receiver, and can also be equipped with a gas generator, mostly used to make distilled water. [0003] The existing laboratory devices for fixing flasks mostly use iron frames and clamping bolts, such as CN208894077U. This device mainly relies on screws to clamp the neck of the flask, causing the flask to tilt easily, which is very inconvenient for the experimental operation. Therefore, a A sturdy and stable...

[0003] The existing laboratory devices for fixing flasks mostly use iron frames and clamping bolts, such as CN208894077U. This device mainly relies on screws to clamp the neck of the flask, causing the flask to tilt easily, which is very inconvenient for the experimental operation. Therefore, a A strong and stable distillation flask holder is all that is needed
