Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a control panel that is installed outdoors and houses electrical equipment inside.

[Conventional technology]

A control panel that houses electrical equipment has a door on the front for installing and inspecting the internal equipment. A double door is attached to the door so as not to occupy too much space when the door is opened.

In addition, when a double door is provided, an intermediate frame is provided at the joint between the right door and the left door to prevent rainwater, dust, etc. from entering the control panel through the gap between both doors.

This intermediate frame limits the size of the equipment when it is stored, and gets in the way during wiring assembly work, so a structure in which it is removable has been proposed (Utility Model Publication No. 60-19443). (see official bulletin).

[Problem that the invention attempts to solve]

In order to ensure the safety of internal equipment and the stability of power supply, the door of such control panels, especially those installed on ordinary pavements such as switch towers, must be opened only by personnel in charge. A locking handle is provided for easy access. Conventionally, in the case of double-swinging doors, a handle with a lock is provided on each of the left and right doors.

In general, locking handles have a complicated structure and are expensive, so providing them on both the left and right doors leads to an increase in costs. Furthermore, since this locking handle is exposed on the outside of the control panel, there is a possibility that the lock of each door may become unusable or destroyed due to mischief or the like.

The present invention was devised in view of the above circumstances, and aims to reduce the cost of the control panel and reduce the possibility of destruction due to mischief or the like.

[Means for solving problems]

In order to achieve this purpose, the control panel of the present invention is
In a control panel in which a double door is provided at the front opening of an outer box, an intermediate frame is removably attached to the mating part of both doors, a handle device for one door is attached to this intermediate frame, and a handle device for one door is attached to the intermediate frame. The handle operation part is configured to be covered by the surface of the other door when the other door is closed.

〔Example〕

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

FIG. 1 is an exploded perspective view of an embodiment in which the present invention is applied to a control panel, FIG. 2 is a cross-sectional view of the intermediate frame portion, and FIG. 3 is a front view showing details of the locking device according to the present invention.
FIG. 4 is a rear view thereof.

In these figures, 1 indicates the outer box of the control panel, 2 indicates the left door, and 3 indicates the right door. Screw holes are provided in the upper and lower frames 1a and 1b of the outer box 1, and the intermediate frame 4 is fixed to the screw holes with tightening screws. When installing equipment or performing wiring work, the intermediate frame 4 can be removed by removing the tightening screws so that the work will not be hindered. The left door 2 is provided with an external handle device 5, 5 with a lock on the front, and the intermediate frame 4 is provided with an external handle device 5, 5 with a lock.
Engagement metal fittings 6, 6 into which the engagement rods of the locking handle devices 5, 5 are fitted are fixed by welding or the like.
FIG. 5 shows an example of the structure of the locking handle device 5 when the left door 2 is viewed from the back. That is, a handle arm 11 is connected to a handle shaft 10 that rotates 90 degrees when the handle of the locking handle device 5 is operated.
A rod 13 is connected via 2. The rod 13 is a lock guide 14,1 welded to the left door 2.
5 and 16 to vertically move up and down, and a midway portion thereof is provided so as to pass through a hole 6a of an engaging metal fitting 6 that extends from the intermediate frame 4 and is fixed.

Furthermore, an internal handle device 7 for holding the right door is attached to the intermediate frame 4, as shown in FIGS. 2 to 4. This internal handle device 7 may be one without a lock, and in this embodiment, the handle device (for example, manufactured by Takigen Seizo Co., Ltd. , small flat handle A-250,
(Refer to Utility Model Publication No. 56-3494) is shown. This means that when the lower part of the lever 7a is pressed, the engagement piece 7b rotates toward the horizontal position, that is, upward in the drawing, and when the upper part is pressed, it rotates downward by 45 degrees. On the other hand, an engagement seat plate 8 is fixed to the back surface of the right door 3 by welding or the like, and the engagement piece 7b
When it rotates to the horizontal position, it engages with the engagement piece 7b, and when it rotates to the diagonal position, it separates from the engagement seat plate 8. This engagement seat plate 8 is formed with a guide piece 8a for guiding the engagement piece 7b.

In addition, there is a U-shaped bent part 3a on the edge of the right door 3.
is formed, and a rubber gasket 9 is attached thereto, so that when the left door 2 is closed, the L-shaped bent portion 2a comes into contact with the left door 2, thereby eliminating rattling of the right door 3.

In this way, if the left door 2 is closed and locked after the right door 3 is closed and held by the internal handle device 7, the right door 3 will be locked at the same time as the left door 2.

[Effect of idea]

As explained above, in the present invention, a removable intermediate frame is provided at the mating part of double doors, the lockless internal handle device of one door is attached to this intermediate frame, and the lockless internal handle device of one door is attached to the intermediate frame. - The handle operation part for opening is covered by the surface of the other door when the other door is closed. Therefore, the locking handle device, which has a complicated and robust structure, only needs to be attached to one door, which can reduce costs. Furthermore, the possibility of the locking device being destroyed by mischief or the like is halved, and the number of locking and unlocking operations can also be reduced. Furthermore, when the control panel is closed, both doors are visible on the outside.
Since only the handle device of one door is visible, it looks better.
