DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a viscometer elevating device used for measuring the viscosity of a viscous liquid.

[0002]

2. Description of the Related Art There are various types of viscous liquids, such as industrial products such as adhesives and fillers, and foods. When manufacturing or using such viscous liquids, furthermore, control and adjustment. At times, it may be necessary to appropriately measure the viscosity of the viscous liquid.

Therefore, conventionally, a viscometer for measuring the viscosity of such a viscous liquid has been known, but a known viscometer has a structure as shown in FIGS. 5 to 8, for example.

[0005] That is, in FIGS. 5 and 6, reference numeral 1 denotes a viscometer main body. The viscometer main body 1 has an output shaft which is rotated by a driving force of a motor incorporated therein and a coaxial shaft with the output shaft. A spindle 5 having an impeller 4 positioned in the beaker 3 at the lower end thereof,
When the output shaft and the spindle are connected by a spiral spring (not shown) and the output shaft is rotated at a predetermined speed, the spiral spring is caught by the viscosity of the viscous liquid contained in the beaker 3, The viscosity of the viscous liquid is measured and displayed based on the angle difference.
Is a column 7 vertically held by a stand 6
The support 7 is supported via a support rod 9 on a support 8 which is guided so as to be movable only in the axial direction of the support 7.

The specific structure of the support 8 is shown in FIG.
As shown in FIG. 8, the support 8 has a slider 12 having a through hole 11 vertically penetrating a column 7 having a rack 10 formed in the axial direction. It has a rack gear 13 meshed with the rack 10, an operation knob 14 fixed to the rack gear 13, and a fastening screw 15 for positioning the slider 12 at a predetermined position of the column 7.

Then, the viscometer main body 1 fixed to the support body 8 via the support rod 9 is moved in and out of the beaker 3 with respect to the impeller 4 provided below the viscometer main body 1. To move the slider 1 up and down, the rack gear 13 is turned by turning the operation knob 14.
The viscometer 2 moves up and down along the column 7, and when the slider 12 reaches a desired position on the column 7, the slider 12 and the column 7 are fastened by operating the fastening screw 15.
Is positioned at a desired position.

However, in such a conventional elevating / lowering device for the viscometer main body 1, since the operation knob 14 is rotated to raise and lower the viscometer main body 1, the viscometer main body 1 is moved. Cannot be moved up and down quickly. Further, in the elevating mechanism using the rack and the rack gear, since the rack 10 must be formed in the axial direction of the support shaft 7, the manufacturing cost of the support shaft is particularly high and the price is high. Further, when the weight balance of the elevating device is uncertain in the connection by the rack and the rack gear, the viscometer main unit may fall down, and the viscometer main unit may be damaged.

The present invention has been made in view of the above.

[0009]

SUMMARY OF THE INVENTION The operation of raising and lowering the viscometer main body for positioning the impeller provided in the viscometer main body in the beaker or pulling out the impeller from the beaker is made possible by a one-touch method. An object of the present invention is to quickly and easily raise and lower the meter main body, and to simplify the raising and lowering mechanism of the viscometer main body to reduce the cost of the raising and lowering mechanism.

It is another object of the present invention to improve the operability and workability of the positioning of the viscometer main body at a fixed position by one-touch operation.

[0011]

In order to achieve the above object, according to the present invention, a viscometer main body is supported via a parallel link on a column which is standing and held by a stand base, and the parallel link is further connected to the column. It is characterized in that it is a viscometer elevating device having a position means for positioning on the side surface of the viscometer main body by pressing frictional force.

According to a second aspect of the present invention, in addition to the first aspect, a viscometer in which a tension spring is interposed between an upper link and a lower link constituting a parallel link in order to enhance the weight balance of the viscometer main body. It is a lifting device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS.

Reference numeral 21 denotes a stand base on which a column 22 is fixed vertically. An arm base 23 is attached to the upper end of the support 22. One end of each of parallel links composed of an upper link 24 and a lower link 25 is provided on each of left and right side surfaces of the arm base 23. It is supported by The other ends of the upper and lower links 24 and 25 are connected to the viscometer main body 27.
The side wall surface, that is pivotally supported by the axles 28.

The structure of the viscometer main body 27 is the same as that described in the conventional example, and is not the gist of the present invention.
The description of the internal structure of the viscometer main body 27 is omitted.

Reference numeral 29 denotes a beaker placed on the stand 21. The beaker 29 contains a viscous liquid whose viscosity is to be measured. Further, in order to measure the viscosity of the viscous liquid, it is necessary to sink the impeller 31 attached to the tip of the spindle 30 expended downward from the viscometer main body 27 into the viscous liquid in the beaker 29. In addition, when the impeller 31 is positioned in the viscous liquid or pulled up from the viscous liquid, an operation of vertically moving the viscometer main body 27 together with the spindle 30 and the impeller 31 is required.

32 is an upper link 24 and a lower link 25
The tension balance of the tension spring 32 maintains the gravity balance of the viscometer main body 27 at a desired position.

Reference numeral 33 denotes a fixed plate which is supported by a pair of upper and lower support shafts 28 attached to the viscometer main body 27. The fixed plate 33 cooperates with a side surface of the viscometer main body. The upper link 24 and the lower link 25 are positioned so as to sandwich the same, and a fastening screw 34 screwed to the viscometer main body 27 is penetrated through the fixing plate 33. A handle 35 is integral with the fastening screw 34 and can rotate the fastening screw 34.

In order to position the impeller 31 provided in the viscometer main body 27 in the beaker 29, or to position the impeller 31 in the beaker 29, In order to raise the impeller 31, the handle 35 is rotated to operate the fixed plate 3.
When the handle 35 is moved up and down after the tightening force of the upper link 24 and the lower link 25 is loosened by 3, the viscometer main body 27 is moved up and down while maintaining the vertical position, and the viscometer main body 27 is moved to a desired vertical position. When the handle 35
Is rotated in the screw fastening direction, the upper link 24 and the lower link 25 are fixed to the viscometer main body 2 by the fixing plate 33.
7, and the vertical position of the viscometer main body 27 is determined.

As described above, in this embodiment, the vertical position of the viscometer main body 27 can be quickly and easily determined by a very simple operation of rotating the handle 35. In addition, since the positioning is ensured by the fastening means using the screws 34, it is possible to prevent the viscometer body from accidentally slipping off and damaging the spindle 30, the impeller 31, and the like.
