孔６が形成されている。 In Figure 1, 1 is a handle mounting hole 2 on one side.
It is a metal door body with a transparent structure, and side plates 3 are formed on the four sides of the door, which are folded back on the inner surface.
A bent portion 4 having a U-shaped cross section is formed on the inner surface on the handle side. A doorstop bushing mounting hole 5 is transparently provided in this bent part 4, and the doorstop bushing can be attached here and the strength of the door body 1 can be improved by making this bending part 4 act as a rib. . In the present invention, through holes 6, 6 are provided at the upper and lower corner portions where the bent portion 4 is connected to the upper and lower side plates 3, 3. The shape of the through hole 6 is free, but the hole edges on the upper and lower side plates 3 should be at the same height as the inner surfaces of these side plates 3. In this embodiment, a semicircular through hole 6 as shown is formed.

である。(Function) The door configured in this way has a hanger 8 inserted into the hanger hole 7 formed in the upper side plate 3 as shown in the figure.
It is suspended by inserting the tip of the tube, and is first subjected to pretreatment such as degreasing, cleaning, and chemical conversion treatment. In this process, the entire door is sequentially immersed in the pretreatment liquid, but when the door is lifted out of the liquid, the bottom corner of the folded part 4 is fixed as shown in Figure 2. The processing liquid is discharged from the through hole 6 whose hole edge on the side of the lower side plate 3 is at the same height as the inner surface of the side plate 3, and no processing liquid remains in the lower corner portion. After the pretreatment, the door is then immersed in an electrocoating tank to be coated with electrocoating.In this case, as shown in Figure 3, the door is immersed in an electrocoating bath through the through hole 6 provided in the upper corner. Since air escapes from the corners, there is no possibility of paint defects due to air bubbles.
Therefore, with the door of the present invention, there is no risk of residual treatment liquid or insufficient penetration of paint, and a complete painting process is possible.

用的価値は極めて大きいものである。(Effect of the invention) As explained above, the invention provides a through hole in which the edge of the hole on the upper and lower side plates is at the same height as the inner surface of the side plate in the upper and lower corners of the bent part with a U-shaped cross section. By providing this door, it is possible to completely paint the inner surface of the corner part without causing pre-treatment defects or unpainted parts, so it can be used as a door for electrical equipment storage boxes that solves the drawbacks of the conventional ones. Its practical value is extremely great.
