る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting mechanism for an indicator for fluid, and more specifically, an indicator that is incorporated in an operating circuit of a fluid pressure device and indicates the fluid pressure in the circuit is attached to a panel. A mechanism for fitting the indicator instrument to the cover member, positioning the cover member integrally with the indicator instrument in the hole formed in the panel, and then tightening with the tightening member. The present invention relates to a mounting mechanism for a fluid indicating instrument which is configured so that the indicating instrument can be easily attached to a panel and can have a beautiful appearance.

路の指示計器等と共に装着することが好ましい。For example, conventionally, in a fluid pressure circuit for operating a fluid device such as a pneumatic motor and a pneumatic cylinder, the state of the fluid in the fluid pressure circuit, for example, as an indicator instrument for visually observing the fluid pressure from the outside Pressure gauges are widely used. In this case, it is preferable that the pressure gauge is mounted together with an indicator of an electric circuit on a panel that can be more easily confirmed than in a place where it is difficult to visually recognize the inside of the machine.

より前記圧力計をパネルに対して固着しているのが現状
である。By the way, the pressure gauge is generally composed of a substantially columnar main body and a flange portion that surrounds the main body and integrally projects. Therefore, when the pressure gauge is attached to the panel, screw holes corresponding to a plurality of holes formed in the flange portion of the pressure gauge are formed in the panel, and screws are provided in these holes and the screw holes. At present, the pressure gauge is fixed to the panel by charging.

観を呈することが到底困難であるという欠点が指摘され
ている。However, since the flange portion of the pressure gauge is formed around the axially intermediate portion of the body portion of the pressure gauge, the body portion often projects considerably from the panel surface. Moreover, there is no external appearance in agreement with other indicating instruments attached to the panel, for example, indicating instruments of the electric system due to a difference in manufacturing series, and accordingly, a plurality of indicating instruments arranged on the entire panel. It has been pointed out that it is extremely difficult to present a unified aesthetic among instruments.

という不都合が指摘されている。Further, when the pressure gauge is mounted on the panel, as described above, it is necessary to form a screw hole corresponding to the hole formed in the flange portion of the pressure gauge on the panel. However, the drilling work is extremely troublesome because the work is performed on site. Therefore, the work efficiency for mounting the pressure gauge and the like on the panel is significantly reduced. On the other hand, if a screw hole for mounting the indicator on the panel is preliminarily drilled, there is a positional difference between the screw hole and the hole formed in the flange portion of the pressure gauge. If it happens,
It has been pointed out that it is very difficult to attach the pressure gauge to the panel.

が困難であるという不都合がある。Further, since the main body of the pressure gauge is formed in a substantially cylindrical shape, a pipe line for introducing pressure fluid is screwed into the fluid pressure introduction port of the pressure gauge attached to the panel for connection. In doing so, there is an inconvenience that the pressure gauge rotates and it is difficult to connect the pipeline.

する。The present invention has been made to overcome the above-mentioned inconvenience, and includes a cover member having a hole formed in the axial direction and a tightening member that engages with the cover member. Then, the cover member and the indicating instrument are integrally fitted into the hole formed in the panel, and then the tightening member is attached to the cover member from the back surface of the panel to instruct the panel. An object of the present invention is to provide a mounting mechanism for a fluid indicating instrument which is configured to fix the indicating instrument, thereby facilitating the work of attaching the indicating instrument and providing an excellent appearance.

を未然に防止する。First, in the state shown in FIG. 1, the pressure gauge 16 is fitted into the hollow portion 12a of the cover member 12. In this case, the cover member 12 covers substantially the entire outer peripheral surface of the pressure gauge 16 and, in the tapered portion 24 of the cover member 12, the tongue pieces 27a to 27h.
The diameter of the end of the pressure gauge 16 is enlarged by the outer peripheral surface of the pressure gauge 16 until it becomes a substantially straight state. The tongue pieces 27a to 27h forming the tapered portion 24 by expanding the diameter as described above.
The pressure gauge 16 is gripped by the elastic force generated in the. Further, the protrusion 3 formed on the tongue piece 27a of the cover member 12
2 engages with a recess defined in the outer peripheral surface of the pressure gauge 16, whereby the pressure gauge 16 is a hollow portion of the cover member 12.
The inconvenience of causing an unnecessary turning operation in 12a is prevented in advance.

Screw displacement in the opposite direction,
By simply removing the tightening member 14 from the cover member 12, the pressure gauge 16 and the cover member 12 can be integrally removed from the panel 40. When it is necessary to replace only the pressure gauge 16 with another indicator, press the pressure gauge 16 from the back side of the cover member 12 and the tightening member 14 attached to the panel 40. It is possible to remove the cover member 12 and replace it with another indicating instrument.
