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
The present invention relates to the physics facility field, particularly pull the automatic horizontal that method is measured the suspension ring of Coefficient of Tension of Liquid Surface.
Background technology
The suspension ring that the current method that pulls is measured in the Coefficient of Tension of Liquid Surface are to hang on the hook of measuring instrument through three one metal wires, through manual a certain tinsel wherein, make suspension ring be in horizontality, and horizontal adjustment is difficulty relatively.
Summary of the invention
The present invention overcomes the difficulty that the method that pulls is measured the horizontal adjustment of the suspension ring in the Coefficient of Tension of Liquid Surface, and designing one can be through the suspension ring device of scrolling realization automatic horizontal.
The present invention solves the technical problem of technical solution adopted is: do not horizontal rings of each part by the surface tension is uneven, the rings and rings hanging device to achieve point contact, through the action of surface tension and the advantage of less rolling friction so does the level of rings before taking off in La automatic level.
The invention has the beneficial effects as follows: automatic horizontal is regulated, and reduces the experiment regulating step, simplifies experimentation, improves conventional efficient, improves experimental precision.

Embodiment
Suspension ring use aluminum alloy materials; Form by suspension ring sphere top 1, trapezoidal hole 2 and suspension ring cylinder 3; Suspension ring cylinder 3 is cylinders of an external diameter 10.2cm, internal diameter 10cm, height 0.5cm; Suspension ring sphere top 1 is a diameter 10cm who on cylinder, adheres to, the hemisphere face of thickness 1mm, and trapezoidal hole 2 is trapezoidal holes of four long length of side 6.5cm on hemisphere face, digging, the long 4.5cm of minor face, high 4.5cm.
The suspension ring suspender is made up of hollow tubular 4, pillar 5, bead 6 and messenger wire 7; Hollow tubular 4 length 10cm, internal diameter 3mm, external diameter 5mm; Use aluminum alloy materials, 4 one-tenth 90 degree of two hollow tubulars intersect, and the point of crossing is intercommunication; Can one of them pipe be cut, another one pipe reach through hole, be welded then; Pillar 5 is welded on the hollow tubular point of crossing, is used to support bead 6, and pillar 5 is hollow aluminium alloy right cylinder, thickness 1mm, the height 3cm of diameter 5mm, bead diameter 5mm.Messenger wire 7 passes from hollow tubular 4, comes out from the trapezoidal hole 2 of suspension ring, at last messenger wire is hung on the hook of stalagmometry appearance.
Rings 1 and the top of the spherical ball 6 is in point contact state, it will cause a slight imbalance force moves rings, rings cylinder 3 will not level the surface tension of the top 1 is moved to the spherical rings, finally guarantee La off the cylinder 3 when the bail is level.
