Abstract

PURPOSE: To obtain an indicating instrument in which a limit region display can be changed and which can deal easily with a change in the specification of an object to be measured by a method wherein a variable-limit-region display panel is fixed to a front plate so as to be turned. CONSTITUTION: A dial 2 is displayed on a front plate 2a at a case body 7, and a scale part is formed in the circumferential direction so as to match a rotation according to the measuring amount of a pointer 3. A variable-limit-region display panel 1 is turned by making use of the center of a measuring instrument as an axis by means of an indication lever which is extended to the radial direction at the rear of a through hole 2b which has been made in the front plate 2a in parallel with the dial 2, and a normal region 1a and a limit region 1b are displayed according to colors. A hole is worked between measurable regions on the dial 2 so that a limit region display can be confirmed. In addition, the display panel 1 is fixed to the front plate 2a by a fixation implement 4 such as a screw or the like via a coupling rod 6, and the coupling rod 6 can be moved along the through hole 2b. Consequently, when the fixation implement 4 is loosened, the coupling rod 6 adjusts the rotation of the display panel 1, and the range of the regions 1a, 1b is made variable. Thereby, the setting of the limit region can be changed easily from the outside of the measuring instrument.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicating instrument applicable to all industries.

[0002]

2. Description of the Related Art When a wide-angle instrument is displayed in a limit area (usually in a red band), the dial (color, current, voltage, etc.) or more is individually manufactured to color the dial.

Alternatively, a wide-angle instrument with a pointer has been applied.

[0004]

When a specification of an object to be measured is changed after manufacturing and delivering a wide-angle instrument equipped with a limit area display, a limit area display according to the rating after the specification change is provided. There was a problem that the wide-angle instrument of the above had to be manufactured and delivered again.

The present invention provides a wide-angle instrument equipped with a mechanism capable of variably setting the limit region display, whereby not only the productivity of the instrument can be improved by eliminating individual production, but also the instrument An object of the present invention is to provide an indicating instrument that can easily change the limit area even when the object to be measured is changed after manufacturing and delivery.

[0006]

The indicating instrument of the present invention is mounted by passing through a dial displayed on the front plate of the case body and a through hole formed in the front plate substantially in parallel with the dial. There are a pointer that rotates according to the measurement amount, a variable limit area display panel behind the through hole that displays the normal area and the limit area, and a fixture that fixes and stops the variable limit area display panel on the front plate. It is characterized by having.

[0007]

In the indicating instrument of the present invention, a dial is displayed on the front plate of the case body, a through hole is opened in the front plate almost in parallel with the dial, a pointer is attached through the front plate, and the measured amount is measured. The variable limit area display panel is mounted behind the through hole to display the normal area and the limit area, and the variable limit area display panel is fixed and stopped.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the indicating instrument of the present invention will be described below. 1 and 2, the dial 2 is a case body 7
It has a graduation portion which is displayed on the front plate 2a and has a graduation formed in the circumferential direction in accordance with the rotation of the pointer 3, for example. The through hole 2b is a hole formed in the front plate 2a substantially in parallel with the dial 2. The pointer 3 is an indicator device that is attached through the front plate 2a and that rotates according to the measured amount. The variable limit area display panel 1 is a part of a ring which is a display panel for displaying the normal area 1a and the limit area 1b behind the through hole 2b and has a support rod extending in the radial direction so that the center of the instrument is centered. It can be rotated. The fixture 4 is, for example, a screw, and fixes the variable limit region display board 1 to the front plate 2 a via the connecting rod 6 and stops it. Protective cover 5 is front plate 2
The front of the case body 7 is protected by covering a. FIG. 3 is a sectional view taken along the line III-III in FIG. 2, showing the outer shape of the variable limit area display panel 1.

That is, although FIG. 1 shows a speedometer, any wide-angle instrument such as a voltmeter, an ammeter or the like may be used. 2 shows a side view (cross section). The display of the limit area of a normal wide-angle instrument is colored on the dial 2 with red or the like, but in this embodiment, the variable limit display panel 1 is provided on the back side of the dial 2.

On the dial 2, holes are made between the measurable areas so that the display of the limit area can be confirmed (0 to 1 in FIG. 1).
Between 00 rpm). Further, FIG. 3 shows a front view of the variable limit area display panel 1. The variable limit area display panel 1 can freely rotate around the center of the wide-angle instrument, and the normal area 1
a and the limit area 1b are color-coded. Further, by making the variable limit area display panel 1 longer than the measurable area,
The structure is possible even if the entire measurable region is the limit region.

One side of the connecting rod 6 shown in FIG. 2 is vertically fixed to the variable limit area display panel 1 and is movable along the through hole 2b. Rotate and adjust area 1
The range of a and 1b is changed. One side of the other connecting rod 6 is connected to the fixture 4 of the variable limit area display panel 1 provided outside the protective cover 5. To change the setting of the limit area, use fixture 4
This can be done by loosening the, and the structure is such that the setting can be easily changed from outside the instrument.

Further, after setting, the variable limit area display panel 1 is structured so as to be fixed to the protective cover 5 by tightening the fixing screw 4 so that the variable limit area display panel 1 does not easily move. In this case, although the protective cover 5 is also provided with a circumferential slit, it can be fixed by pressure contact with the connecting rod 6 inside the cover while the case body is covered with the protective cover 2.

[0013]

According to the present invention, the individual production can be reduced, so that the productivity can be improved and the specification change of the measured object can be easily dealt with.
