Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to measures for waterproofing and soundproofing casings of power generators, air conditioners, and the like.

[Conventional technology]

FIG. 5 is a sectional view showing a conventional casing disclosed in, for example, Japanese Utility Model Laid-Open No. 62-12422, in which 1 and 2 are upper and lower frames, 3 is an intermediate frame, and 4 is the above frame 1. 3 is a cover provided between the frame 2 and 3, 5 is a cover provided between the frames 2 and 3, 6 is a packing, and 7 is a fixing screw.

That is, in such a structure, first, the frames 1, 2, and 3 are fixed to each other, and the covers 4 and 5 processed in the shape of a concave box are fixed to the frame formed in a rectangular shape with the packing 6 attached to the inside. The fixing screw 7 is used for fixing.

[Problems to be solved by the device]

Since the conventional casing is configured as described above,
When fixing the frame part and the cover, due to the manufacturing variations of the frame and the cover, it is not possible for them to adhere to each other. There was a problem such as not being able to do it.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a casing which can absorb manufacturing variations and can be easily assembled.

[Means for Solving the Problems]

In the casing according to the present invention, the framework is composed of a lower underframe, an upper frame, and a vertical frame. A shielding bar is fixed to the outer surface of each frame, and removable vertical frames are attached to the lower underframe and the upper frame, respectively. The shield bars are arranged so as to project, and the shield bars are fixed in a concave shape so that the lower underframe and the upper frame face each other, and each shield bar is configured to be engaged through diagonally parallel voids. is there.

[Action]

In the casing of this invention, a shielding bar is arranged on the surface of the casing, and the packing of the door and the shielding bar are connected with a certain degree of freedom to absorb variations in manufacturing such as hinge mounting of the panel and frame structure. As a result, it is possible to improve the assemblability, functionally prevent water from entering from the outside, and reduce external leakage of noise generated by internal equipment.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 15 is an upper frame, 16 is a lower underframe, and 17 is this upper frame.
A removable vertical frame arranged between 15 and the lower underframe 16 to connect them, 18 is a shield bar fixed to the upper frame 15,
Reference numeral 19 is a shield bar fixed to the vertical frame 17, 20 is a shield bar fixed to the lower underframe 16, and 21 is a diagonally parallel void formed between these shield bars.

2 is a side view of FIG. 1, FIG. 3 is a perspective view showing the overall structure of the casing, and 22 is a vertical frame having the same function as the frame 17.

Further, FIG. 4 shows a cross section taken along line IV-IV in FIG.
Is a cover to protect the equipment inside the casing with rainwater and to block the noise generated from the equipment, 24 is packing, 25
Is a hinge for opening and closing the cover 23.

Next, the operation will be described. The casing is assembled into a cube by fixing the upper frame 15 and the lower underframe 16 that are integrally manufactured by a removable vertical frame 17 and a vertical frame 22. At the time of this assembly, since the shield bars 19 of the vertical frames 17 and 22 are arranged so as to project to the upper frame 15 and the lower underframe 16, they act as stoppers and are inclined to the shield bars 18 and 20. The processed part is assembled as a guide, the casing is assembled into a cube, and the gap becomes obliquely parallel to prevent water from entering from the outside. Therefore, the equipment provided in the casing is protected from rainwater and dust. Further, in order to prevent noise generated from the equipment, as shown in FIG. 4, the cover 23 is fixed to the vertical frame 22 by the hinge 25 to open and close, and the packing 24 provided around the cover 23 shields when closed. Achieve that function by squeezing the bar 19.

Although the shield bar is circular in the above embodiment, it may be rectangular. Further, in the above-mentioned embodiment, the hinge is used so that the panel can be opened and closed. However, when the panel is screwed without using the hinge, the same effect as that of the above-mentioned embodiment is obtained.

[Effect of device]

As described above, according to the present invention, the shielding rod is provided on the outer surface of the casing, and the casing of the equipment to be installed and used outdoors has a dustproof and waterproof structure, and can be manufactured at low cost as a low noise type. .

[Brief description of drawings]

FIG. 1 is a front view showing a casing according to an embodiment of the present invention, FIG. 2 is a sectional side view of FIG. 1, FIG. 3 is a perspective view showing the whole constitution of the present invention, and FIG. 4 is a sectional view taken along line IV-IV of FIG. 5, and FIG. 5 is a sectional view showing a conventional casing. In the figure, 15 is an upper frame, 16 is a lower underframe, 17 is a vertical frame, 18, 19,
20 is a shield rod and 21 is a void. The same reference numerals in the drawings indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] 1. A casing framework is constructed such that a lower underframe and an upper frame are connected by a removable vertical frame, and a shield bar is provided on the outer surfaces of the lower underframe and the upper frame in parallel with the bottom surface of the casing. The shield bar is fixed to the outer surface of the vertical frame in a direction perpendicular to the bottom surface of the casing, and the shield bar fixed to the vertical frame is projected and arranged on the lower underframe and the upper frame. However, the shield bars of the lower frame and the upper frame are configured to be concave so that they face each other, and the shield bars of the lower frame and the shield bars of the vertical frame and the shield bars of the upper frame and the shield bars of the vertical frame are A casing characterized in that the casings are arranged so as to face each other with a gap in parallel with each other.
