Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for attaching an inner door of a distribution board comprising a box body that houses various electric devices, a frame that is attached to the periphery of the opening of the box body, and an inner door that covers the wiring of the electric device.
[0002]
[Prior art]
As shown in FIG. 4 , the inner door mounting structure in the prior art attaches a panel 33 on which equipment is placed to the bottom surface of the box body 31 via an inner door mounting part 32. The inner door mounting bracket 34 is mounted on the opposite side of the inner door mounting component 32 from the portion mounted on the box body 31, and the inner door (not shown) is mounted on the inner door mounting bracket 34. Further, the mounting position of the inner door mounting bracket 34 is fixed.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, if the panel 33 is removed at the time of construction or the like, the inner door attachment part 32 is also removed, and parts such as attachment screws of the removed inner door attachment part 32 are lost or the panel 33 is attached again. There was a risk of mistakes. Further, since the mounting position of the inner door mounting bracket 34 is fixed, the mounting position cannot be moved, and the inner door cannot be divided. For this reason, it is impossible to change a single-opening box to a double-opening door, limiting the mounting position of the equipment to be stored, and the box may be multifaceted. If it does so, an installation place will also become large, and the electrical connection wiring between apparatuses was needed, and there existed a fault that it took an effort.
[0004]
[Means for Solving the Problems]
Therefore, the present invention aims to provide a distribution board inner door mounting structure that facilitates panel mounting / removing work, and the structure is provided with mounting holes in the bent portion of the frame, and the inner door mounting. The fitting is characterized in that a screw hole facing the attachment hole is formed, a holding fitting is hinged, and the inner door fitting fitting and the holding fitting sandwich the bent portion of the frame and are screwed .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The inner door mounting structure of the distribution board according to the present invention includes an inner door mounting bracket and a pressing bracket hinged to the inner door mounting bracket, and is screwed with the bent part of the frame body sandwiched between the inner door mounting bracket and the inner door mounting bracket. Install the inner door. To remove the panel during construction, remove the frame from the box body with the inner door mounting bracket attached.
[0006]
The inner door attachment structure of the distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
The box body 1 stores various electrical devices, and a frame 3 is attached to the periphery of the opening 2 of the box body 1. The device is mounted on the panel 4 and attached to the box body 1, and wiring of the electrical equipment is stored inside. The distribution board 5 is configured by covering with a door (not shown). The present invention relates to an inner door mounting structure.
[0008]
Frame 3, 26, the bent portion 6 is formed in a stepped shape, provided the mounting holes 7, 27 the bent portion 6, when mounting the inner door mounting brackets 8, 24 to the mounting hole 7, 27 The inner door mounting brackets 8 and 24 are screwed so as to sandwich the pressing bracket 25 from the outside . The inner door mounting bracket 8 is formed by screwing a pressing bracket, and is provided with a screw hole 9 at a position opposite to the mounting holes 7 and 27 provided in the frame 3 , so that the frames 3 and 26 are boxed. The screw hole 9 and the mounting holes 7 and 27 are opposed to each other from the inside of the main body 1, and the screw 10 is inserted and fastened and fixed. Further, the shapes of the inner door mounting brackets 8 and 24 are changed depending on their use, such as the bracket 8a for supporting the inner door or the hinge pin holders 8b and 8c depending on the mounting position.
[0009]
A screw insertion hole 11 is provided on the periphery of the opening 2 of the box body 1, and the frame bodies 3 and 26 to which the inner door mounting brackets 8 and 24 are attached are screwed to the screw insertion hole 11.
[0010]
When removing the panel 4 during installation, the inner door is left frame 3 Toritsui may by removing 26 from the box body 1, the inner door mounting brackets 8, 24 of the prior art because it is attached to the frame body 3, 26 Thus, it is not necessary to remove the inner door mounting brackets 8 and 24 , respectively. Further, the mounting holes 7 and 27 for attaching the inner door mounting brackets 8 and 24 may be the bent portion 6 in FIG. 2 or the bent portion 6 in FIG .
[0011]
The inner door mounting bracket 24 is formed by buttering the pressing bracket 25. When the inner door mounting bracket 24 is mounted in the mounting hole 27 provided in the frame body 26, the inner door mounting bracket 24 is screwed so as to sandwich the pressing bracket 25 from the outside.
[0012]
【The invention's effect】
As described above, in the distribution door inner door mounting structure according to the present invention , the inner metal bracket is attached to the inner door mounting bracket, and the bent portion of the frame is sandwiched between the inner door mounting bracket and the pressing bracket. Since the inner door mounting bracket can be fixed more securely by screwing, and the inner door mounting bracket is screwed into the mounting hole, the panel on which the device is placed can be removed independently, improving workability. In addition, the screws that hold the inner door mounting parts are not lost.
