Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the attachment of instruments such as pressure gauges and thermometers to panels in frames.

[Conventional technology]

Conventionally, instruments having a flange for fixing to a panel have been of the intermediate flange type (FIG. 4) or the front flange type (FIG. 5), depending on the position of the flange.

The flange is manufactured separately by casting, die-casting, etc. and is then joined to the instrument, which causes high costs.

In addition, the flange is attached to the instrument by joining the flange 20 to the frame 1 of the instrument in the intermediate flange type, and to the lid 4 in the front flange type.

Furthermore, in the intermediate flange type, as shown in FIG. 6, there is also one in which the flange 20 is press-fitted into the frame 1 using a metal press.

[Problem that the invention attempts to solve]

As mentioned above, forming flanges on instruments has the disadvantage that the flanges must be joined separately, resulting in high costs.

Therefore, the purpose of this invention is to provide the instrument frame 1 with the same function as the flange, omit the flange, and correct the high cost.

[Means for solving problems]

This idea is to form two or more bent pieces 6 by bending appropriate parts of the side wall 5 outward, and after placing the supporting stand 2 and the viewing window 3 on the wall side 5 in sequence, the lid 4 is placed on top of them. A flange 8 of the lid 4 covers the bent piece 6.

[Effect]

This idea is based on the frame 1 instead of joining flanges.
Since the bent piece 6 is formed by bending the flange, no flange is required.

By using this bent piece 6, the instrument can be fixed to the panel even without a flange by bolting (screws) (Fig. 2) or by holding the panel from above and below as shown in Fig. 3. be able to.

Moreover, since the flange 8 of the lid 4 covers the folding piece 6, the strength of the folding piece 6 can be increased and the appearance of the instruments can be improved.

〔Example〕

An embodiment of this invention will be described based on the drawings.

FIG. 1 shows the outer case of the instrument, in which 1 is a frame 2 for supporting instruments such as a pressure gauge and a thermometer, 3 is a viewing window, and 4 is a lid.

The frame 1 is made by press molding metal, and is made by partially bending the side wall 5 of a cylindrical container with a bottom outward to form three bent pieces 6 at equal intervals. There is. Further, a screw hole 7 for attaching the lid 4 is formed in the side wall 5.

The support stand 2 is for supporting the viewing window 3, and is an integrally molded product of metal, plastic, or the like.

The viewing window 3 is made of transparent glass plate or vinyl chloride,
It is a transparent plate such as acrylic.

The lid 4 includes a flange portion 8 and an upright portion 9.

The method of assembling these is to sequentially place the support stand 2 and viewing window 3 on the frame 1 from above, put the lid 4 on top of it, match the screw hole 10 of the lid 4 with the screw hole 7 of the frame 1, and fix it with the screw 11. .

The standing portion 9 of the lid 4 covers the support base 2 and the viewing window 3,
The flange portion 8 covers the bent piece 6.

Next, a method for fixing the assembled instrument to the panel will be explained. There are two ways to do this.

(1) Bolt fastening (Figure 2) Bend piece 6 of frame 1, flange 8 of lid 4, and panel 12
A bolt hole is made in the hole, and the instrument is fixed with a bolt 13.

In this fixing method, the panel 12 is
If a female thread is formed in the bolt hole, the instrument can be secured by simply working from the front of the panel.

(2) Method of not making holes in the bent piece (Fig. 3) Fix the bolt 14 to the bottom surface 1a of the frame 1, and insert the meter from the front of the panel 12. And panel 1
2. After inserting a holding plate 15 made of a channel or the like into the bolt 14 on the rear surface, a nut 16 is attached. Then, by tightening the nut 16, the panel 12 is sandwiched between the presser plate tip 15a and the bent piece 6, and the instrument is fixed.

In this fixing method, since bolt holes are not drilled in the bent piece 6, the degree of protrusion of the bent piece 6 can be reduced, and the limited panel area can be used effectively.

Note that the holding plate 15 does not necessarily need to be located directly below the folded piece 6 as shown in FIG. Further, the number of tips 15a is not limited as long as it is two or more.

Further, the method of fixing the lid 4 to the frame 1 may be such that the lid 4 is press-fitted into the frame 1. According to this press-fitting method, the screw 11 and the screw holes 7 and 10 are not required, and it is possible to reduce costs and improve the appearance.

[Effect of idea]

Since this invention has the above structure, the flange can be omitted, and the cost can be reduced by reducing the number of parts.

Further, since the bent piece 6 can be easily formed by integral molding using a press, manufacturing is extremely easy compared to the conventional method of joining flanges.

Furthermore, since the flange 8 of the lid 4 covers the folded piece 6, both strength and appearance are comparable to those of the prior art.

Claims (1)

[Scope of utility model registration request] A bent piece 6 is formed by bending an appropriate part of the side wall 5 outward.
After the supporting stand 2 and the viewing window 3 are sequentially placed on the side wall 5, the lid 4 is placed over the support base 2 and the viewing window 3, so that the flange 8 of the lid 4 covers the bent piece 6. A frame for instruments that has a mounting part for the panel.
