Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a panel box used in a distribution board.

(Prior art) Conventionally, as shown in FIG. 5, as a panel box for both exposed type and push-in type, an inner frame B is attached to the periphery of the opening of the main body A. There is a door C that is hinged so that it is located inside the side plate D and the four side plates D of the door C are flush with the four side plates E of the main body A.
Since there is not enough room in the area where the
A stopper fitting F was welded to the back of the door C to prevent the paint from coming off when it hits the main body A.

(Problems to be solved by the invention) In the conventional model, the stopper fitting F was attached to the door C by welding, which made workability difficult.Moreover, it was difficult to apply paint to the parts that would be in the shadow of the stopper fitting F. There were some leftovers that had to be corrected.
Furthermore, since the door C tilts due to its own weight when the box is attached, the door C hits the middle frame B when the door C is closed, making it difficult to open and close it smoothly. Furthermore, middle frame B
Since it is formed by cutting off the rear end of the bending process, there are problems such as burrs generated in the cutting process protrude toward the outside surface, requiring deburring work.

(Means for Solving the Problems) The present invention solves the above-mentioned problems. It is easy to install the member that prevents the door from hitting the main body, and it can be installed after welding, and the door can be tilted. This was done to provide a panel box that can be opened and closed smoothly even when the door is opened, and the inner frame can be easily processed. In a panel box that is located inside the side plate and has a hinged door so that the four side plates are flush with the four side plates of the main body, when the door is closed on the outer periphery of the middle frame, the door is parallel to the side plate of the door. At the same time, a notch is formed in the corner opposite to the hinge part of the middle frame, and a cutout is formed in the bottom of the side wall parallel to the side plate of the main body, so that when the door is closed, there is a cutout between the door and the main body. forming a brim located on the side wall,
The present invention is characterized in that a corner member is fitted that forms a protrusion for guiding the door, which protrudes from the side plate of the inner frame and comes into contact with the side plate of the door when the door is closed.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. 1 is the main body. Reference numeral 2 denotes a middle frame which has a side plate 2a formed on its outer periphery and is attached to the periphery of the opening of the main body 1. The middle frame 2 has a fixed hinge fitting 3 fixed to one side and a notch 4 formed at the other corner. ing. Reference numeral 5 denotes a door, and when the door 5 is closed, the inner frame 2 is located within the four circumferential side plates 6 of the door 5, and the four circumferential side plates 6 are parallel to the side plates 2a of the inner frame 2 and in plane with the four circumferential side plates 7 of the main body 1. It is hinged to the middle frame 2 with a movable hinge metal fitting 8 so that it is aligned with the center frame 2. 9 hangs an engaging leg 11 from one piece of the approximately triangular front plate part 10, forms a collar 13 at the bottom of the side wall 12 on the other two sides, and hangs from the front plate part 10 to the collar 13 approximately in the center of the side wall 12. The corner member 9 is a corner member on which a guiding protrusion 14 is formed, and the corner member 9 is fitted and fixed to the notch 4 of the middle frame 2 by engaging the engaging legs 11 with the end faces of the notch 4 of the middle frame 2 .

(Function) As described above, the collar 13 is formed at the bottom of the side wall 12 of the corner member 9 that is fitted and fixed in the notch 4 formed at the corner of the inner frame 2, and the side wall 1
Since the guiding protrusion 14 is formed approximately in the center of 2,
By fitting the corner member 9 into the notch 4 after painting the inner frame 2, which is an extremely simple operation, the door 5 is attached to the main body 1 at the brim 13 where the side plate 6 of the door 5 contacts when the door 5 is closed. It also prevents the door from hitting the door 5.
When closing the door 5, the guide protrusion 1 of the side wall 12 of the corner member 9 protrudes from the side plate 2a of the inner frame 2.
4, the door 5 can be opened and closed smoothly without the risk of hitting the inner frame 2.Furthermore, since the notch 4 is formed at the corner of the inner frame 2, the inner frame 2 can be bent after cutting. As a result, burrs generated during cutting can be directed toward the inner surface, eliminating the need for deburring.

(Effects of the invention) As described above, according to the invention, it is easy to install the corner member 9 that prevents the door 5 from hitting the main body 1, and it can be installed after painting. This has the excellent effect of providing a panel box that does not require correction, can be opened and closed smoothly even if the door 5 is tilted, and is easy to process the inner frame 2.
