Embodiment 1 FIG.
FIGS. 9 to 11 illustrate a panel casing device according to Embodiment 1 of the present invention, and FIG. 9 is a cross-sectional view corresponding to the line AA in FIG. FIG. 10 is a cross-sectional view corresponding to the BB line of FIG. 1 corresponding to the salt damage prevention structure of FIG. 9, and FIG. 11 is a CC line of FIG. It is arrow sectional drawing corresponded to. In the drawings, the same reference numerals denote the same or corresponding parts.
Compared to Reference Example 1 and Reference Example 2 above, if the specifications to enhance water tightness and dustproof property or to withstand salt damage in salt damage areas such as along the coast when installed outdoors, refer to the above reference. In the dustproof or normal watertight specification shown in FIGS. 7 and 8 in Example 2, as shown in FIGS. 9 and 10, the door 2 is provided between the outer peripheral end 2 a and the opening 11. A packing 5 </ b> B that can seal the inner side including the hinge member 6 when 2 is closed is provided. Specifically, the seal portion is made to have a double structure by fitting the packing 5B into the outer peripheral end 2a of the door 2. In this case, the water tightness is enhanced, and the rotating portion of the hinge member 6 is disposed inside the outer packing 5B, so that it is possible to prevent the occurrence of rust due to a sea breeze or the like.

  Furthermore, when watertightness between the housing body 1 and the base 7 is required, the fastening bolts 9 of the housing body 1 and the base 7 shown in FIG. 11 are loosened, and the jack bolt 8 for lifting the housing is turned. The casing main body 1 is lifted, the seal packing 5C is attached to the gap formed by the lifting, the jack bolt 8 is returned to the original position, and the casing main body 1 and the base 7 are fixed again by the tightening bolt 9. Thereby, the effect of watertightness can be obtained. The nut 8a is fixed to the bottom of the housing body 1 by welding. Moreover, although the example in which the jack bolt 8 and the fastening bolt 9 are installed inside the housing body 1 has been shown, it goes without saying that the installation position may be outside the housing body 1.

As described above, according to the first embodiment, one end is attached to the attachment surface 11a of the opening 11 of the housing body 1 so that the seal packing 5A can be interposed according to the sealing specification. A flange member 3 having a door abutting portion 3b formed so that the end portion protrudes forward from the opening 11 and the packing 5 can be interposed between the protruding end portion and the door 2 in accordance with a sealing specification. By doing in this way, the housing | casing main body 1, the door 2, and the flange member 3 can be shared among the models from which a sealing specification differs. For this reason, the manufacture of the casing device can be started regardless of the specifications such as the installation location and the dustproof or watertightness. Even when the specifications are changed during the production of the housing device, the change can be easily made by changing the packing 5, the seal packing 5A, or the packing 5B , and the flange member 3 . This eliminates the need for remanufacturing the casing device.

Conventionally, since the hinge member is attached to the hinge mounting bracket, it is necessary to attach it separately to the opening, and there are many attachment operations. In the first embodiment, the hinge member 6 is fixed to the flange member 3. Therefore, the effect of shortening the installation work can be obtained. In addition, since the chassis body 1 can be manufactured regardless of the installation location, the number of types is reduced, and the metal fittings are manufactured only when necessary, so that the production amount of the chassis device is consolidated, the production efficiency is improved, and the cost is low. The effect that it can provide is also acquired. Furthermore, by providing the jack bolts 8, it is possible to obtain the effect of reducing the movement time and preparation time of the crane truck as compared with the case where the housing body 1 is conventionally lifted by a crane.
In addition, although the case where the cross-sectional shape of the flange member 3 was L-shaped was illustrated in the said Embodiment 1, it cannot be overemphasized that a cross-sectional shape is not specifically limited. In addition, naturally, the shape of the opening 11, the door 2, the packing 5, etc., the position of the mounting surface 11a, the number of doors 2, the configuration of the hinge member 6 and the like can be appropriately modified or changed within the scope of the present invention.
