Description
Technical field
The present invention relates to the clips (it is vertical to adjust capillary) that fixed capillary viscosimeter is used in the measurement of kinematic viscosity
Or it is similar this at work for adjusting vertical device.
Background technique
Viscosity is the intrinsic attribute of object, and the measurement of kinematic viscosity widely is applied to produce, liquid motion viscosity
Measurement is the measured value at a certain temperature of regulation, it is by capillary constant, temperature, timer, capillary in viscosity determinator
In whether position vertical etc. that factors determine.
Capillary viscometer, which is placed in, at present and adjusts vertical method in viscosity determinator is joined using gravity (plummet)
It is realized according to three screws adjusted on installation clip equipment level face, user bothers in operation, it has not been convenient to use.
Summary of the invention
The present invention is intended to provide a kind of device for capillary viscometer, as intermediate connector, for clip and
Viscosity determinator connection, adjusts the vertical of testee, guarantees the vertical of capillary viscometer capillary in the measurements.
A kind of device for capillary viscometer, including the upper connector and lower connector being connected through a screw thread, and
Sphere between upper connector and lower connector；
The upper connector upper end closed lower end is open, inside have a cylindrical cavity, and hold on inner wall under the cavity
Be provided with screw thread, have on the upper surface of upper connector one perpendicular to the threaded cylinder in upper surface and surface；
The lower connector upper end opening lower end closed, inside have a cylindrical cavity, and in the lower end of lower connector
A through-hole coaxial with the cylinder is provided on face, the upper end outer surface of lower connector is provided with screw thread；
The spherome surface has a cylindrical body, and the axis of cylindrical body crosses the centre of sphere of sphere, and cylindrical outer surface is provided with
Screw thread, cylindrical body passes through the through-hole of lower connector lower end surface and the outer diameter of cylindrical body is less than through-hole internal diameter.
The upper connector and lower connector are the equal cavity cylindrical body of outer diameter.
There is and the annular solid that is connected coaxial with lower connector in the upper end of the lower connector, under the outer diameter of annular solid is less than
The outer diameter of connector is provided with screw thread on the outer surface of annular solid.
There is an annular protrusion on the cylindrical body, the outer diameter of annular protrusion is greater than the outer of through-hole on lower connector lower end surface
Diameter.
Signified clip is the clip with connection screw thread hole in the present invention, and retained part is used for capillary viscometer
In clamp capillary, threaded hole connect with the present invention, and device through the invention is connected with the clip for pressing from both sides capillary, adjustable hair
Capillary viscometer verticality.
The through-hole internal diameter of lower connector lower end surface is greater than the outer diameter of cylindrical body on sphere, and so there are one therebetween
Annular gap, as the rotation space of the relatively upper and lower connector of sphere, when verticality is adjusted in place, relative rotation connects above and below
Junctor makes the two clamp sphere, so that the relative position of fixed three, guarantees verticality.
Sphere is clamped in upper connector and lower company by adjusting the upper connector and lower connector of threaded connection by the present invention
Between junctor, then the cylinder (or cylindrical body of sphere) on upper connector is connect with clip, and the cylindrical body on sphere passes through down
Connector (or cylinder on upper connector) is simultaneously fixed on viscosity testing device, is then arbitrarily adjusted according to the vertical requirement of adjustment
It is whole, so that the capillary portion verticality of clip clamping is adjusted.
Compared with prior art, the invention has the characteristics that:
(1) easy for installation, the cylindrical body on the cylinder or sphere on upper connector is connected by when use with clip respectively, ball
Cylinder on cylindrical body or upper connector and viscosimeter (such as heating and heat-insulating device, such as the lid of water bath on body
Son) it is connected；
(2) easy to adjust, sphere is compressed by connector in relative rotation and lower connector, clamps hair so as to adjust clip
The angle of tubule adjusts the vertical of testee, guarantees the vertical of capillary viscometer capillary in the measurements.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
