Flask placing mechanism and water bath kettle

Abstract

The invention provides a flask placing mechanism and a water bath kettle comprising the flask placing mechanism. The flask placing mechanism comprises a placing seat, which comprises an annular seat body with a variable diameter and an elastic compression ring piece, wherein the lower end of the annular seat body can be attached to the bottom wall of a pot body; and an expansion component, which is used for enabling the annular seat body to perform outward expansion action. The annular seat body comprises m fan-shaped blocks which are mutually independent and circularly arranged at intervals, a space defined by all the fan-shaped blocks forms a placing cavity used for placing flasks, a gap between every two adjacent fan-shaped blocks is set as a fan-shaped block gap, the expansion component comprises a pushing and pressing ring piece located above the annular seat body and m expansion plate pieces extending downwards in the axial direction of the pushing and pressing ring piece, the lower ends of the m expansion plate pieces are inserted into the gaps of the m fan-shaped blocks respectively, the two side walls, in the circumferential direction, of each expansion plate piece are symmetrically arranged, and the width between the two side walls is gradually reduced from top to bottom.

Description

technical field [0001] The invention belongs to the technical field of fixing a flask of a water bath, and in particular relates to a flask placement mechanism and a water bath including the flask placement mechanism. Background technique [0002] The constant temperature water bath is an essential tool for education and scientific research in biology, genetics, virus, aquatic products, environmental protection, medicine, hygiene, biochemical laboratories and analysis rooms. When the flask has less internal solution, it is prone to swaying and floating and tilting and spilling during the heat preservation or heating process, causing the water in the water bath to pollute the neck of the flask and even the solution inside the flask. For this reason, usually adopt the preparation clamp above the pot body to clamp and fix the flask. [0003] However, it is necessary to manually tighten and loosen the jaws of the fixing clip every time the flask is taken out, which is cumbersom...
