Description

[Detailed Description of the Invention] This invention relates to a pointer holding device for various meters that is capable of holding the pointer in any desired position.

Conventionally, in various meters used for various purposes, the operating pointer indicates the appropriate scale on the character display board, such as when indicating the maximum value or minimum value, or when a certain period of time has elapsed. When indicating the scale on the plate, the inspector must read the instantaneous scale indicated by the pointer, so it is difficult to read the scale, or it is very rough and there are many misreadings, resulting in extremely inaccurate inspection. The reality is that it is a situation.

Therefore, the central issue among those involved was to develop a device or mechanism that would eliminate the above-mentioned inconveniences and that would be able to easily and accurately read the scale indicated by the pointer.

This invention aims to solve the above-mentioned inconveniences of conventional meters and to provide a pointer holding device for various meters that has a simple structure and is easy to manufacture.The structure is explained as follows with reference to the drawings. It is.

This invention consists of a fixing plate 3 having a cutout 2 extending from the center lower part to the lower end of a pair of left and right mounting parts 1.
and a traction arm 6 which is formed integrally and continuously with the fixed plate 3 at the lower part, is released by the cut groove 4, has a protruding strip 5 at the upper part, and is stretched to an appropriate length from the left and right ends of the upper part. The pointer 9 of the meter body 8 is formed from the fixed plate 3.
The fixing plate 3 is attached and fixed to the character display plate 10 of the meter main body 8 so as to be located between the main body 8 and the operating plate 7.
An electromagnet 12 is made to protrude to the rear through a hole 11 drilled in the meter body 8, and is separately fixed to the rear of the meter body 8.
This pointer holding device for various meters is characterized in that the end of the pulling arm 6 is locked to a movable rod 13 which is attached to a movable rod 13 and is operated by the action of an electromagnet 12.

In the above configuration, the pointer holding device of this invention is formed from the fixed plate 3 and the actuating plate 7. Both plates 3 and 7 are punched out of a single plate, and a pair of left and right mounting plates are attached to the upper part of the fixed plate 3. A protruding strip 5 capable of holding the parts 1 in contact with each other and a bent part 14 at the lower part of the actuating plate 7 can be manufactured by folding the respective parts.

Further, both the plates 3 and 7 are integrally and continuously formed at the lower part, but are separated by cutting grooves 4 in other parts, and the fixed plate 3 is connected to the character display board 10 of the meter body 8. The mounting portion 1 is fixed with screws 15 or the like, and the actuating plate 7 is in a released state.

The materials of the plates 3 and 7 may be anything, such as a thin aluminum plate, phosphor bronze, or stainless steel, and are not specified.

The pointer 9 shown in the drawings is designed so that only its tip comes into contact with the surface of the character display board 10 through the protrusion 5 when the operating plate 7 is operated, but the pointer 9 is not limited to this. It is also possible to design the pointer 9 so that most of it comes into contact with the pointer 9 instead of the pointer 9.

Next, to explain the operating state of this invention, first, due to the action of the electromagnet 12 electrically connected by the input cord 16, the magnetic terminal 17 of the electromagnet 12
The movable rod 13 is activated, and
The actuating plate 7, which has the bent end of its pulling arm 6 locked to the movable rod 13, is pulled in the direction of the arrow in the figure, thereby causing the protruding strip 5 of the actuating plate 7 to However, the pointer 9 is pushed toward the character display board 10 and the pointer 9 is stopped and held at an arbitrary position with the tip of the pointer 9 in contact with the surface of the character display board 10.

Note that holding the pointer 9 at an arbitrary position means, for example, when the highest current value is indicated, when the lowest current value is indicated, or when a certain period of time has elapsed. Refers to the position of pointer 9.

As explained above, according to the pointer holding device for various meters of this invention, a single plate is punched out and formed into a fixed plate and an actuating plate, and then folded, so that the mounting part, protruding stripes, etc. Since it forms each part, it is easy to manufacture and has a simple structure, and the manufacturing cost is very low and economical, making it suitable for mass production. Because it can reliably hold the scale, the inspector can accurately and easily read the scale indicated by the pointer, eliminating misreading and other inaccuracies that occur in the past. This provides great convenience for meter reading operations, and the pointer is pressed halfway into contact with the surface of the character display board by a protruding strip on an actuating plate operated by an electromagnet. Therefore, the fulcrum of the pointer, that is, the bearing part, will not be damaged due to this holding.

Furthermore, this pointer holding device can be easily attached to various types of off-the-shelf meters, thereby improving off-the-shelf meters.
