Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a viscometer, and particularly to a viscometer for measuring the viscosity of a fluid using a portable method.

[Conventional technology]

In general, viscometers have become indispensable as means for measuring the flow characteristics of fluids (liquids).

Among these viscometers, an example of a portable type viscometer that has been widely adopted is shown in FIG. This fifth
In the figure, numeral 1 indicates a pedestal made of cast metal and formed into a substantially U-shape. A stand 3 fixed with a nut 2 or the like is provided perpendicularly from a predetermined position of the pedestal 1, and a spur gear 3A is provided in a predetermined section on this stand 3. The main body 4 for measuring viscosity is attached to the stand 3 via a gear mechanism 4B that meshes with the flat gear 3A and is movable up and down by turning a height adjustment screw 4A.

On the other hand, main components for viscosity measurement are built into the main body part 4. The principle of this viscosity measurement is that when the rotation of a synchronous motor (not shown) is transmitted to a rotor immersed in the fluid to be measured 5 via a spring (not shown), a viscosity is generated on the outer periphery of the rotor 6. Frictional torque acts, so make use of it. In other words, since this torque and the spring force are in balance, the rotation is steady.
The magnitude of the torque is proportional to the value read by the scale plate 7 directly connected to the motor shaft, which is the angle of deviation of a pointer (not shown) fixed to the rotor shaft. Therefore, the absolute viscosity is determined by multiplying this indicated value by a conversion constant. Here, pedestal 1
The knobs 8, .

[Problem that the invention attempts to solve]

However, in the conventional example described above, the entire pedestal 1 is made of cast metal and has a fixed length, so the container 9 for the fluid to be measured 5 is too large and cannot be placed at a predetermined position within the pedestal 1. There may be cases where it is not possible, etc.
In addition to operational inconveniences, packaging becomes unnecessarily large-scale when moving and installing the viscometer or shipping it from the manufacturer, and additional space is required for storage, resulting in packaging costs, logistics costs, etc. This has led to the inconvenience of pushing up product costs.

The purpose of the present invention is to provide a practical viscometer with further cost reduction, which has been developed in view of the conventional example.

[Means for solving problems]

Therefore, the present invention includes a substantially U-shaped pedestal formed to surround a container for the fluid to be measured, and a main body that is disposed at a predetermined position from the pedestal via a stud part and measures the viscosity of the fluid to be measured. In the viscometer, the pedestal has a pedestal main body formed into a substantially V-shape, and a V formed by both side surfaces of the pedestal main body.
It is constructed with a pair of legs that can be detachably attached along the shape of the letter, thereby achieving the above object.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In FIG. 1, the viscometer according to the present embodiment includes a pedestal 20, a column 21 as a stand attached to a predetermined position of the pedestal 20, and a height-adjustable gear mechanism connected to the column 21. It is composed of a main body section 22 and the like for viscosity measurement.

The pedestal 20 includes a pedestal main body 30 formed of a steel member having a predetermined height and a substantially V-shape, a pair of legs 31 that can be detachably attached to the pedestal main body 30,
It consists of 31. In the V-shaped pedestal main body 30, as shown in _FIG . ₂
(θ ₂ > θ ₁ ) are shaped so that they are different, so
Either of the two can be selected as needed. On the other hand, the legs 31, 31 are rectangular parallelepipeds having a predetermined length and are formed in a hollow state, and are mounted through the opening surface 30C of the pedestal main body 30, and are mounted with screws 3.
3 and 33, it is detachably attached. FIG. 3 shows this situation. Here, 34,...
..., 34 is an adjustment knob for adjusting the horizontal height during measurement.

Further, the main body portion 22 measures the viscosity based on the same principle as the conventional example. In other words, the rotation of a synchronous motor (not shown) is controlled by a spring (not shown).
The torque is transmitted to the rotor 37 immersed in the fluid to be measured 36 in the container 35 through the viscous friction torque acting on the outer periphery of the rotor 37 to effect a phase delay. Then, this phase delay is detected and calculated and measured by a predetermined control section (not shown), and the display section 4
It is configured to digitally display 0. Here, 41 is a power switch, and 42 is a stop switch. Further, 43 is a clamp.

Next, the operation of the above embodiment will be explained.

First, as mentioned above, as for how to assemble the pedestal 20, as shown in FIGS. 4 1 and 2, the legs 31,
The angle formed by the angle 31 can be arbitrarily selected to be wide or narrow (θ ₂ or θ ₁ ). That is, the pedestal main body 30
If it is attached along both outer side surfaces 30A, 30A, a narrower angle θ ₁ will be obtained as shown in FIG. A wider angle θ ₂ can be obtained, so it is selected depending on the size and purpose of the container, and the mounting screws 33, .
..., 33 will be installed. Then, the container 35 for the fluid to be measured 36 is appropriately placed in the V-shaped space of the pedestal 20, and the handle 51 is turned to lower the main body 22 along the spur gear 21A in the support column 21 using the gear mechanism. Further, the rotor 37 and the sleeve 52 with an open bottom are immersed in the fluid 36, and the viscosity is measured according to a predetermined procedure (see FIG. 1).

Therefore, the width of the legs 31, 31 of the pedestal 20 can be selected depending on the purpose, which improves operability when preparing for measurement, and also improves versatility regarding installation locations. . On the other hand, the legs 31, 31 can be detachably attached even if the angle of the V-shape formed by them is either wide or narrow, so the packaging required for shipping or moving installation can be made more compact. In the end, packaging costs and logistics costs can be reduced.
Furthermore, in this embodiment, as shown in FIGS. 1 and 2, the V-shape is designed to have approximately the same length l in the vertical direction, so in the case of a wide angle (θ ₂ ) Even in the case of Fig. 2), consideration is given to reducing the danger of preventing the viscometer from falling over.

In addition, in the above embodiment, the legs 31, 31 of the pedestal 20
Although the cross section of is formed into a hollow rectangular shape, the present invention is not necessarily limited to this, and the cross section may be round, for example.

[Effect of idea]

As described above, according to the present invention, there is provided a substantially U-shaped pedestal formed to surround a container for a fluid to be measured, and a pedestal that is disposed at a predetermined position from the pedestal via a stud part, and which measures the viscosity of the fluid to be measured. In the viscometer having a main body part to be measured, the pedestal is approximately V
It is composed of a pedestal body formed into a letter shape and a pair of legs that can be detachably attached along the V-shape formed by both sides of the pedestal body. By separating the legs into a pair of legs and making them removably attachable, the entire unit can be stored more compactly during moving installation and shipping, reducing packaging costs, logistics costs, etc. Therefore, it is possible to provide a practical portable viscometer that can reduce the product cost.
