Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monitoring panel that performs intensive monitoring by integrating a display section with an operation section, and its purpose is to correspond to the internal unit of the display device equipped with a lamp device. To provide a monitoring panel in which a display panel for displaying monitoring status on the front side can be easily removed.

The display section of a conventional desk-type centralized monitoring panel is a combination of an operation section 1 and a display section 2 as shown in FIG. 1, and the display panel 3 has a load name printed thereon.

This load name changes for each subject, and even if the subject is the same, the contents may change due to changes in specifications during construction, changes in load due to renovation, etc. Therefore, it is necessary to change the contents of the display panel 8 in response to these changes.
The display section 2 has a display panel 3 fitted inside a box body 4, and bolts 6,
6,... are erected, the display panel 3 is passed through the bolts 6, 6... and positioned, and the display lamps 7, 7,...
・Place the inner container 8 housing the same into the bolts 6, 6... and screw the nuts 9, 9,... onto the bolts 6, 6... from the back side inside the box body 4. , and fix the back plate 10 with the mounting screws 11, 11, . . .
It is installed on 2.

Therefore, in order to change the contents by removing the display panel 3, the display panel 3 cannot be removed unless both the back plate 10 and the internal unit 8 are removed, which has the disadvantage that it is time-consuming to replace the display panel 3. As an improvement for this purpose, as shown in FIG. 2, the inner container 8, display panel 8, and decorative frame 13 are housed and attached in order from the front of the opening of the box 4, and the mounting screws 11, 11, . . . It is considered that the frame 13, the display panel 3, and the inner device 8 are installed from the front side of the frame 13 into the opening □ opening 5 of the box 1, but in this case, other mounting screws 14, The inner unit 8 is attached to the box body 4 at 14, and the display panel 3 is similarly attached to the box body 4 using other mounting screws 15, 15.
The display panel 3 can be removed from the front side by removing only the mounting screws 11, 11 and 15, 15, but the mounting screws 11, 11, . . . on the surface of the frame 13 can be removed.
Since the head of the frame 13 is exposed, the surface of the frame 13 will be scratched when screwing the screws every time the display panel 3 is changed, and if the frame 13 is made of metal, the coating may be damaged. This will cause the metal to peel off and rust, resulting in a decrease in value.

Furthermore, due to the drawbacks mentioned above, as shown in FIG.
, 16 to open the display panel 3 as a unit and contact the □ part □ green, and then bolts 6, 6, . . .
・Protrudes to the rear side through the display panel 3 and the mouth edge of the entrance part, and is attached to the frame body 1 by screwing the nuts 17', 17', .
3 so that the screw heads are not exposed on the surface side of the frame 13, or as shown in FIG. A configuration in which the female thread 17a is brought close to the back surface of the box body 4 and is attached using the mounting screws 11, 11 is also conceivable.
In the former case, the nuts 17', 17',
It is extremely difficult to install and remove the pillars 17, 17, .
・Because of its long size, it is not easy to install, remove, or manufacture, and it is easy to change, and the mounting screws 11, 11,...
・It is also difficult to screw in.

The present invention has been made in view of the above reasons.

The embodiment of the monitoring panel of the present invention will be described below with reference to FIGS. 4 and 5, in which the same parts as in the conventional example are given the same reference numerals. A monitoring panel for monitoring has a front opening □ and support pins 18, 18 are set upright on the inner wall, slide holes 19 are provided in the support pins 18, 18 to engage them, and a screw 20 is screwed into one end. A box body 4 equipped with a connecting rod 22 whose other end is an engaging end 21;
An indicator lamp 7 mounted in the box body 4 from the entrance part of the box body 4
The inner container 8 with the inner container 8 attached, the display panel 3 attached on the inner container 8, and the opening green 5 of the box body 4 are brought into contact with each other, and the inner wall 3a is engaged with the engaging portion of the connecting rod 22. It consists of a frame 13 on which a fixture 24 having an engaging part 23 is erected, and the screw 20 of the connecting rod 22 is engaged with the bottom wall 4b of the box body 4, and the bottom wall 4 is
b The engaging part 2 between the connecting rod 22 and the fixture 24 is operated from the outside.
1 and 23 are made to appear inside and outside the box body 4 as a monitoring board. In addition, 25 is a retaining ring that connects the camphor 2.
2 is held on support pins 18, 18.

To remove the display panel 3, rotate the screw 20 to move the connecting frame 22 in the direction of arrow A, and then remove the engaging portions 21, 23.
When it is closed in the front direction of the box body 4, by moving the frame body 13 in the direction of arrow B, the engaging portions 21 and 23 are disengaged, and the frame body 13 can be separated from the box body 4. .

This operation exposes the display panel 3 to the front, so that the display panel 3 can be replaced by removing the mounting screws (not shown) of the display panel 3. To attach the display panel 3, the engaging part 23 of the fixture 24 of the frame body 13 is engaged with the engaging part 21 of the connecting rod 22 and temporarily fixed, and then the box body 4
Attach the cotton by turning the screw 20 on the back side.

The connecting birch 22 moves in the opposite direction to the arrow A and pulls the fixture 24, and the bottom wall of the frame 13 comes into contact with the entrance green 5 of the box 4 and stops, completing the installation of the display panel 3. .

In the above operation, the display panel 3 is attached to the entrance edge 5 of the box body 4 with mounting screws, or is held between the inner device 8 and the frame body 13.

As described above, according to the present invention, in a monitoring panel that performs intensive monitoring by roughly integrating a display section with an operation section, the monitor panel has a front entrance section, a support pin is erected on the inner wall, and the display panel slides onto the support pin. A box body is made of a connecting rod with a hole provided and a screw screwed into one end and the pond end is the engaging end, and an indicator lamp is installed into the box body from the opening of the box body. an inner container, a display panel mounted on the inner container, and a fitting having an engaging part that comes into contact with the opening edge of the box body and engages with the engaging part of the continuous cassette on the inner wall. It consists of a frame that stands upright, and the screws of the connecting camphor are engaged with the bottom wall of the box body and operated from the outside of the bottom wall, so that the engaging part between the connecting bolt and the mounting frame can be moved in and out of the box body. Since the mounting screws are not exposed on the front side of the frame, problems such as damage to the frame surface or rust caused by operating the mounting screws will not occur, and the screws can be inserted from the back side. The display panel can be installed and removed just by rotating it, which makes replacing the display panel very easy.Also, when fixing the frame, you can engage the engagement part between the connecting bolt and the mounting tool and screw it in place. Since the frame body can be temporarily fixed without tightening the box body, screw tightening work on the back side of the box body is easy, and a distribution board that can be operated satisfactorily even by one person is obtained.
