Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a housing for accommodating a display in an electromagnetic counter, etc., which is attached to a measuring instrument such as an electromagnetic integrating calorimeter and is used to display the integrated measurement value. It is something.

[Prior art]

Conventionally, the electromagnetic counter that displays the integrated calorific value of an integrating calorimeter has been overwhelmingly housed in the casing of the calorific value calculation unit. In addition, it was equipped with a knock-out to facilitate wiring work, and required a small housing, making it difficult to put it into practical use. However, recently, small electronic calorimeters have been developed, and when they are installed in ceiling water pipes in buildings, it is necessary to separate the display unit and install it in any location. There is a need for a display unit that can be easily installed, and there has been a demand for a display housing suitable for this purpose.

On the other hand, conventionally, when installing a display in a case that has a cover with a display window, it is necessary to adjust the mounting status of the display in order to match the display part of the display with the display window of the cover. This has the disadvantage of requiring a large amount of man-hours.

[Summary of the idea]

The present invention has the purpose of satisfying such demands and eliminating the shortcomings of the conventional ones at once. By assembling according to an easy procedure, the display part of the display unit and the display window of the cover can be assembled automatically. The purpose of the present invention is to provide a display casing that completely matches the .

03, a support fitting 201 is locked by a screw 104, and a display 202 using a flange-shaped electromagnetic counter is fixed to this by a spring 203.

Furthermore, a box-shaped cover 301 is fitted to the frame 101 from the front and outside, and the display section 204 of the display device 202 is positioned on the front side of the frame 101 so that it can be viewed from the front. Display window 302
is drilled.

Note that the horizontal parts 102 and 103 of the frame 101
A knockout 105 for piping is formed in the cover 301, and a first protrusion 106 having a wire hole is formed outward near the front edge of the horizontal portion 103. The corresponding portion is formed in an open state, and the protrusion 106
A second protrusion 303 formed in the same manner is provided at a portion opposite to the second protrusion 303, which enables sealing after assembly at the installation site.

In addition, the cover 301 is fixed with screws 304 after being fitted to the frame 101, and strips 305 indicating display units are affixed to the display window 302 of the cover 301. At the same time, a name plate 306 is attached to the lower front surface of the display window 302.

FIG. 2 shows details of the frame 101, in which A is a front view, B is a top view, C is a side view, and D is a bottom view.
7 is formed, and the front edge between these is bent inward to form a mounting portion 1 having a screw hole 108.
09 is formed, and the tip of the protrusion 107 presses against the inside of the front surface of the cover 301, thereby
The fitting stop position of the cover 301 is regulated.

In addition, a knockout 105 is formed approximately at the center of the back side of each of the horizontal sections 102 and 103, and a screw hole 110 for a screw 304 is bored approximately at the center near the front edge of the horizontal section 103. A protrusion 106 having a wire passage hole 111 is formed on the side of the rear side slightly from this.

In addition, from the horizontal parts 102 and 103 to the back part 112
Reinforcing striped embossments 113 are formed on both sides of the groin, while circular embossments are formed on the back surface 112, as well as through-holes 114 for attachment and through-holes for hooking. 115 is drilled.

FIG. 3 shows a support fitting 20 for a flange type display device.
1 is a front view, FIG. 4 is a support fitting 201 for a display without a flange, A is a front view,
B is a plan view, C is a side view, and in FIG. An elongated cut hole 208 corresponding to the screw hole 108 drilled in the mounting portion 109 of the horizontal portion 103 is formed in the abutting edge portion 207, and thereby,
The horizontal relative positions of the mounting portion 109 and the support fitting 201 are regulated.

In FIG. 4, a front part 211, a base part 212, and a back part 213 are integrally formed by bending a sheet metal, and the front part 211 is provided with an edge part 207 and a cutout hole 20 similar to that in FIG. , bent parts 214 are formed upward on both sides of the horizontal part 212 for regulating the mounting position of the display 202, while a back part 213 bent according to the length of the display 202 has , a through hole 215 for attachment is bored.

Note that the dimensional relationship between the edge portion 207 and the through hole 206 and the dimensional relationship between the edge portion 207 and the horizontal portion 212 are determined in correspondence with the display window 302 of the cover 301.

FIG. 5 shows the details of the cover 301, in which A is a front view, B is a side sectional view, and C is a bottom view, with the back surface and the parts corresponding to the knockout 105 and the protrusion 106 of the frame 101 in an open state. It has a box shape, and a display window 30 is provided approximately in the center of the front panel 307 corresponding to the display section 204 of the display unit 202.
2 is bored, and a transparent plate 308 made of transparent acrylic or the like is fixed to the inside thereof by adhesive or the like.

In addition, a long hole-shaped cutout hole 310 is formed from the back side at a portion of the bottom plate 309 that corresponds to the screw 304, and a wire-through hole 311 is formed at a portion of the bottom plate 308 that faces the protrusion 106. A protrusion 303 is formed.

Therefore, if the support fitting 201 is selected from those shown in FIG. 3 or 4 according to the shape of the display 202, the housing can be shared, and when installing, the cover 301 can be removed and screw 104
Support metal fittings 201 and display device 20 by screwing back
2 is removed, the frame 101 is made into a single unit, and the frame 101 is mounted on a wall surface etc. and knocked out 10.
5. Pass the wire from the specified direction by punching,
After connecting the wires to the display 202, the edge portion 207 of the support fitting 201 is brought into contact with the protruding portion 107 of the frame 101, and the mounting portion 10 is connected through the notch hole 208 of the support fitting 201.
By screwing the screw 104 into the screw hole 108 of 9, the mounting part 109 and the support fitting 201 are locked together, and at the same time, the mounting position of the display 202 is regulated. Then, when the cover 301 is fitted, , indicator 2
Display section 204 of 02 and display window 30 of cover 301
2 naturally coincide with each other, and the display section 204 becomes visible from the front through the display window 302.

In addition, in order to fix the cover 301 with the screws 304 and seal it, the protrusions 106, 303
It is sufficient to insert a steel wire or the like into the wire passage holes 111 and 311 of the through hole 1 and fix the ends of the wire with lead or the like.
Since the axes of 11 and 310 are aligned and their inner diameters are large, it is easy to insert the sealing wire therethrough.

However, the frame 101 has horizontal parts 102 and 1
03 may be reversed vertically, or similar ones may be provided on both left and right sides. The same applies to those that fit from above, below, or from the side, and the formation parts of the protrusions 106, 303 may be determined accordingly.
Various modifications are possible.
