Description

[Detailed description of the invention] [Industrial field of application] This invention is for measuring instruments such as pressure gauges, in order to prevent danger or to make them convenient to use. This relates to the mechanism that indicates instructions on the board.

[Prior Art] Conventionally, in order to achieve the above object, the cap on the front of the instrument was removed and a predetermined setting range or setting point was displayed on the dial using paint or the like.

[Problems to be solved by the invention] The above method is not only time-consuming and inefficient, but also requires removing the cap again to change the setting range or setting point. After erasing the data, it is necessary to display the new setting range or setting point again using paint, etc., which is extremely troublesome.

[Means for Solving the Problems] In view of the above points, this invention is based on a meter body that houses a display portion including a dial and a pointer that cooperates with the dial to display measured values. A slit is formed in the cap section on the front side of the dial plate substantially parallel to the dial plate, and a moving piece is provided which includes an adjuster projecting to the outside of the cap part and an indicator indicating a limit value on the dial plate. The movable piece is configured to be separable into two halves to display an upper limit value and a lower limit value by engaging with the slit, and the cap portion is made of an elastic material such as rubber together with the adjuster of the movable piece. This paper proposes a set point defining mechanism for instruments that is covered with a cover.

[Function] Next, an embodiment of this invention shown in the drawings will be described.

In the figure, 1 is a meter body, and although not shown in the figure, a measuring mechanism is built into the base 2 of the meter body 1, and a dial 3 is arranged in front of this mechanism. A pointer 4 at the end display portion of the mechanism cooperates with the dial 3 to display the measured value.

A slit 6 is formed in the cap part 5 at the joint surface between the cap part 5, which together with the base part 2 constitutes the instrument body 1, and the base part 2.
is located in front of the dial 3 and approximately parallel to the dial 3.

A moving piece 9 consisting of an adjuster 7 that clamps the edge of the base 2 of the meter body 1 from the inside and outside, and an indicator 8 located inside the meter body 1 and extending above the dial 3 is engaged in this slit 6. This moving piece 9 shall be
consists of two halves 9a and 9b, and even if these halves 9a and 9b are combined to display one set point (Fig. 3), the half body 9a is the lower limit value, and the half body 9a is the lower limit value, and the half body 9a is the lower limit value. The setting range may be displayed such that 9b indicates the upper limit value (FIG. 4).

After the movable piece 9 is set at a predetermined position as described above, in this invention, the cap part 5 is covered with a cover 10 made of an elastic material such as rubber in order to prevent the set position from shifting. be.

[Effects of the invention] As described above, in this invention, after the moving piece 9 is set at a predetermined position, each adjuster 7 of the moving period 9 is attached to the cap portion 5 of the instrument body 1 made of an elastic material such as rubber. Since the cover 10 is placed over the device, there is no fear that the set position will move due to contact with hands or other objects during use, and risks such as malfunction due to accidental movement can be avoided. This has the effect of improving safety.

Claims (1)

[Scope of utility model registration request] A slit is provided on the front side of the dial approximately parallel to the dial in the cap portion of the instrument body which houses a display portion including a dial and a pointer that cooperates with the dial to display measured values. A movable piece consisting of an adjuster projecting to the outside of the cap portion and an indicator indicating a limit value on the dial plate is engaged with the slit, and the movable piece is set to the upper limit value and the lower limit value, respectively. A set point specifying mechanism for instruments, which is configured to be separable into two halves for display purposes, and is comprised of a cover made of an elastic material such as rubber, which covers the cap portion together with the adjuster of the movable piece.
