Description

[Detailed Description of the Invention] The present invention relates to a pressure gauge vibration isolation plate used for mounting instruments such as pressure gauges.

Conventionally, when instruments, such as pressure gauges, are mounted on a board in an environment with a lot of vibration, the pressure gauge 1 is mounted on a bracket 2 with anti-vibration rubber 3 as shown in FIGS. 1 and 2. It was attached to plate 4 via a shaking stand. This installation method requires a large number of bolts and nuts, and it takes a lot of time to tighten them. Furthermore, the shape of the anti-vibration frame is large, so a large installation area is required, and the shape is not aesthetically pleasing. There were some drawbacks, such as the fact that it was impossible to use.

The purpose of the present invention is to eliminate these drawbacks, provide a pressure gauge vibration isolating plate that has a small shape, a small installation area, is extremely easy to install a pressure gauge, has an excellent appearance, and has a large vibration isolation effect. There is a particular thing. Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 3, the elastic member 5 of FIG. 1 is shown.

The first elastic member 5 is an annular member made of a flexible elastic material, such as nylon resin, and has a hole 6 in the center that is slightly larger than the body of the pressure gauge 1, and a hole 6 in the inner periphery. A burr part 7 that fits the total 1 brim 1a and has a locking tip facing inward.
is provided. A projection 8 that fits into one bolt hole of the collar 1a and positions the pressure gauge 1 is provided on the surface in contact with the collar 1a. (See Figure 6)
The burr 7 is provided with a slot 9 that equally divides its circumference into a required number of parts, making it easier to push the collar 1a of the pressure gauge 1 into it. A groove 10 having a narrow opening and a circular cross-sectional shape at the bottom is provided on the outer periphery of the elastic member 5.

In FIG. 5, the second elastic member 11 is shown.

The elastic member 11 is an annular member made of the same elastic material as the first elastic member 5 and having the same outer diameter, and the inner diameter is considerably larger than the body of the pressure gauge 1.
A burr portion 12 is provided that extends from the inner diameter portion to one side and has a tip facing outward. The burr portion 12 is dimensioned to fit the hole 4a of the plate 4 in which the pressure gauge 1 is to be attached. (See FIG. 6) A protrusion 13 is provided on the side surface of the elastic member 11 having a burr 12, and when the burr 12 is engaged with the plate 4, it fits into the small hole 4b of the plate 4 and the pressure gauge 1 position. The burr 12 is provided with slots 14 that equally divide its circumference into a required number of parts, making it easy to push the burr into the hole 4a of the plate 4. A groove 15 is provided on the outer periphery of the elastic member 11 and has a narrow opening and a circularly expanded bottom.

In FIG. 4, the third elastic member 16 is shown.

The elastic member 16 is an annular member made of the same elastic material as the first elastic member 5. Two protrusions 17 and 1 are provided on the inner circumferential portion to be removably fitted into grooves 10 and 15 provided on the outer circumferences of the first and second elastic members 5 and 11.
7 is provided. Between the protrusions 17, 17, the first and second elastic members 5,
A spacer portion 18 is provided to provide a constant spacing when the two parts 11 are connected.

Next, we will discuss the effect. 3 to 6, when the first elastic member 5 is first inserted from the front side of the pressure gauge 1 and the collar 1a is pushed into the burr 7, the burr 7 is divided into sections separated by slots 9. Opens per side and is easily installed. At this time, the protrusion 8 fits into one bolt hole of the collar 1a and can be positioned. Similarly, the burr portion 12 of the second elastic member 11 is pushed into the hole 4a of the plate 4 to which the pressure gauge 1 is to be attached. The burr part 12 can be opened into each part divided by the slot 14 and easily attached. The protrusion 17 of the third elastic member 16 is pushed into the groove 15 on the outer periphery of the second elastic member 11 which is engaged with the plate 4 to attach it. Groove 1 on the outer periphery of the first elastic member 5 that locks the pressure gauge 1
0 into the other protrusion 17 of the third elastic member 16 to attach it. At this time, it is only necessary to push the pressure gauge 1 into the correct position. It is easy to remove as well as to install.

As is clear from the above explanation, the pressure gauge is extremely easy to install and remove, has a small shape, and has an excellent appearance, and the third elastic member adjusts the distance between the first and second elastic members. The practical effects and advantages are extremely large, such as the ability to increase the vibration-proofing effect.
