Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door of a housing, and more particularly to a double door of a housing used outdoors for mounting electronic devices.

[Conventional technology]

The door of the case of the double door structure for outdoor use is provided with a rubber packing between the door and the periphery of the opening of the case to prevent rainwater and dust for outdoor use.

An example of a door of such a conventional double-door case is shown in FIGS. FIG. 4 is an external perspective view of the entire housing 21, FIG.
4 is a view showing a door portion of a conventional case, and FIG. 6 is a partially cutaway view showing an upper portion of the door of the conventional case shown in FIG. It is a perspective view.

In the figure, 22 and 23 are the bottom part and the bank part of the gutter provided on the periphery of the opening of the housing 21. 24 is a notch formed by cutting the upper and lower edge gutters of the housing 21 in the middle, 25 is a left door attached to the left side of the housing 21 by a hinge 27, and 26 is a hinge 28.
Is a right door that is attached to the right side of the housing 21 so as to be openable and closable by means of the left door 25 and the right door 26. Has been. The protrusion of the stepped portion 29 has a shape that can be accommodated in the cutout portion 24 when the left door 25 is closed. 30 is the lock handle of the left door 25, 31 is the lock handle of the right door 26, with a key. Reference numeral 32 denotes a rubber packing provided between the bank 23 of the gutter provided at the periphery of the opening of the housing 21 and the left door 25 and the right door 26, and is adhered to the inner surfaces of the left door 25 and the right door 26. . 33 is a rubber packing provided between the stepped portion of the left door 25 and the overlapping portion of the edge portion of the right door 26, and is bonded to the inner surface of the edge portion of the right door 26.
A channel base 34 is attached to the bottom surface of the housing 21.

[Problems to be solved by the invention]

In the door of the conventional case described above, the gutter provided at the peripheral edge of the opening of the housing 21 is interrupted by the notches 24 provided at the upper and lower portions, so that the peripheral edge of the opening of the housing 21 and the doors 25, 26. There is a drawback that a gap is created between the two and the housing 21 is not completely sealed. That is, rainwater and dust enter the inside of the housing 21 through the gap of the cutout portion 24, and the rainwater and dust cannot be completely blocked.

It is an object of the present invention to provide a housing door that eliminates the above drawbacks.

[Means for solving problems]

The door of the housing of the present invention comprises a pair of doors that open and close the opening of the housing in a double-door manner, and an edge of the other door provided at one edge of the pair of doors when the pair of doors is closed. A first edge gutter comprising a bottom overlaid with a first elastic packing in between and a first bank along both sides of the bottom; and a peripheral edge of the opening of the housing. A second gutter, a recess provided in the second gutter so that the first gutter when the one door is closed, and the pair of the second gutter. A second bank portion on the side of the door and a second elastic packing provided between the pair of doors when closed, wherein the first gutter is located at least in the recess. One edge gutter is a surface in which the first bank portion is inclined so as to spread toward the front side of the pair of doors, and the second groove is formed in the concave portion. Parts, characterized in that the bent so smoothly continuous with the rest of the corresponding to the bending Moreover the second bank portion of the first Entoi.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an external perspective view of the entire housing 1 provided with a housing door according to an embodiment of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG. Figure 2 shows the door part of the
It is a perspective view which fractures | ruptures a part and shows the upper part of the door of the housing | casing shown in the figure. In the figure, 2 and 3 are the bottom part and the bank part of the gutter provided on the periphery of the opening of the housing 1.

Reference numeral 4 denotes a recess in which the bank portions 4 of the upper and lower edge casings of the casing 1 are recessed corresponding to the protrusion of the edge gutter of the left door 5 described later,
The edge gutters on the periphery of the opening of the housing 1 are smoothly continuous without a break, and the edge gutters of the left door 5 fit into the recesses 4 when the left door 5 is closed. The bottom 2 of the recess 4 of the edge gutter has a narrowed shape. The bank 3 in the recess 4 is bent at a right angle so as not to be recessed and has an oblique shape so that the opening / closing operation of the left door 5 can be smoothly performed.

The left door 5 is openably and closably attached to the left side of the housing 1 by a hinge 7, and the right door 6 is openably and closably attached to the right side of the housing 1 by a hinge 8. Nos. 9 and 10 are left gutter bottom 9 and bottom gutter on left door 5 so that the edges of left door 5 and right door 6 overlap near the center of the housing, and rainwater and dust do not enter inside the housing. A bank portion 10 is provided on both sides of the gutter 9. The bottom portion 9 and the bank portion 10 of the gutter have a shape corresponding to the recess 4. The bank portion 10 has an indented shape that is not a right angle but an oblique shape so that the opening and closing operation of the left door 5 can be smoothly performed similarly to the concave portion 4.

A rubber packing 11 bonded to the bank 3 is provided between the peripheral edge of the opening of the housing 1 and the left and right doors 5 and 6, and when the doors 5 and 6 are closed, the bottom part of the edge gutter of the left door 5 is provided. 9 and the bank portion 10 are also in contact with the recess 4 of the housing 1 with the rubber packing 11 in between,
The entire opening edge of the casing 1 and the doors 5 and 6 are in contact with each other without leaving a gap,
Is completely sealed.

12 is a lock handle for the left door 5 and 13 is a lock handle for the right door 6 with a key. 14 is a rubber packing provided between the bottom 9 of the edge gutter of the left door 5 and the bank 10 and the overlapping portion of the edges of the right door 6, and is bonded to the bottom 9 of the edge gutter of the left door 5 and the bank 10. There is. Reference numeral 15 is a channel base attached to the bottom surface of the housing 1.

[Effect of device]

As described above, according to the present invention, the second curb on the peripheral edge of the opening of the housing is provided with the concavity that is continuously curved corresponding to the first curb of the door, and thus the first curb including the recess is provided. The elastic packing can be continuously provided between the edge gutter and the door without interruption, and the gap between the double door and the housing can be completely removed, thus improving the hermetic sealing of the housing. It is possible to improve the protection against rainwater and dust when used outdoors.
