Abstract

The invention discloses an automatic horizontal hanging ring for measuring the surface tension of liquid by using an abruption method, which relates to the field of physical experimental devices, and especially relates to the automatic horizon of a hanging ring for an experiment of measuring the surface tension coefficients of liquid by using an abruption method. In the current experiments, through manually bending one metal wire in a hanging ring, the hanging ring is in a horizontal state, and the horizontal adjustment of the hanging ring is difficult. The invention adopts the following technical scheme: the surface tension exerted on each part of a non-horizontal hanging ring is not balanced, so that an effect of point contact is achieved between the hanging ring and a wire drawing device; and under the action of the surface tension and through the advantage of small rolling friction, the automatic horizon of the non-horizontal hanging ring is realized before an abruption operation is performed. The hanging device disclosed by the invention has the advantages of carrying out automatic horizon adjustment, reducing an experiment adjusting step, simplifying the experiment process, improving the experiment efficiency, and improving the experiment accuracy.

Description

technical field [0001] The invention relates to the field of physical experiment devices, in particular to the automatic leveling of suspension rings for the experiment of measuring the surface tension coefficient of liquids by the pull-off method. Background technique [0002] The suspension ring in the current pull-off method for measuring the surface tension coefficient of a liquid is hung on the hook of the measuring instrument by three metal wires. By manually bending one of the wires, the suspension ring is in a horizontal state, and the level adjustment is difficult. Contents of the invention [0003] In order to overcome the difficulty of adjusting the level of the suspension ring in the experiment of measuring the surface tension coefficient of the liquid by the pull-off method, the present invention designs a suspension ring device that can realize automatic leveling by rolling. [0004] The technical scheme adopted by the present invention to solve the technical...
