Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cover for an electric equipment casing.

[0002]

2. Description of the Related Art The cover of a power supply casing used for electric welding is designed to cope with heat dissipation during operation, and on the other hand, it must be sealed for waterproof and moistureproof for electric insulation, and must be handled and stored easily. It is required to fill. Since no one satisfies these conditions, conventionally, a sheet, a veneer plate, or the like was merely placed on the top surface of the power supply housing. In addition, a general housing cover has a bag shape, and its side sheet part covers the side surface of the power supply housing, so it is difficult to insert and remove due to protrusions such as switches, and a large space is required for storage and storage. did. Furthermore, it is impossible to deal with heat dissipation such as power supply operation.

Further, as shown in FIG. 7, a housing cover 12 having four corners developed is conceivable, but there is a serious problem that water flows in from an open portion of the top surface of the housing.

A bag-like protective cover for waterproofing and dust-proofing is also used in other electric devices, but the electric device lacks functionality in operating the electric device with the cover attached, or when the cover is attached or detached.

[0005]

The cover, which merely mounts a sheet, a veneer plate, etc. on the top surface of the conventional electric equipment housing, is deformed and displaced by the wind and is not useful for waterproofing. Further, the bag-shaped housing cover has a problem that it is difficult to insert and remove due to the protrusion on the side surface of the housing, and a large space is required for storage.

The present invention has been made in view of the above-mentioned conventional problems, and provides a structure of a cover for an electric equipment casing which is effective for attachment / detachment, waterproofing, storage and the like.

[0007]

A cover for an electric equipment casing according to the present invention includes a quadrilateral central sheet portion placed on the top surface of the electric equipment casing, and can be bent from each side. Four side sheet portions that are extended and can be independently hung along the side surface of the electric device, and two adjacent two side sheet portions at four corners formed by hanging the side sheet portions.
A superposing sheet portion which is provided on any one of the side sheet portions of the side sheet portions facing each other and overlaps the inner surface side of the other side sheet portion in a suspended state, and the other side sheet portion. And a locking portion which is provided in the overlapping sheet portion and locks both sheet portions. Further, in the electric equipment housing cover, a support body extended from the top surface of the housing is installed on the electric equipment housing side of the central sheet portion.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A power supply housing cover for a welding machine according to an embodiment of the present invention will be described below with reference to the drawings.

As shown by the perspective view of FIG.
The support plate 1a placed on the top surface 10a of the power supply housing 10 (see FIGS. 3 and 4) is formed of, for example, a four-sided veneer plate expanded from the plane area of the top surface. The top surface here means the upper surface of the housing. Also, this support plate 1a
An example of a housing cover made of a waterproof sheet made of thick vinyl or nylon as shown in the exploded view in Figure 2 above.
The quadrilateral central sheet portions 1b of 1 are arranged to face each other,
In addition, from the peripheral edge of the central sheet portion, a plurality of side sheet portions 1c are provided, that is, a plurality of side sheet portions 1c, which are hung so as to face and surround the side surfaces of the power supply housing 10 and overlap their side edges.
Is extendedly connected so that it can be bent from the side of the central seat.

These side sheet portions 1c hang down in a state of covering the housing 10. At this time, four open corners of the sheet are formed at the four corners of the housing. 2 adjacent to each corner
The overlapping sheet portion 1e is provided by extending one of the opposite side edge portions 1d of the one side sheet portion, in this example, both side edge portions 1d-1 of the narrow side sheet portions 1c-1 and 1c-2. .
The overlapping sheet portion 1e overlaps the side facing the housing, that is, the inner surface at the side edge portion 1d of the wide side sheet portions 1c-3 and 1c-4 with the side sheet portion hanging down.

Further, the other side sheet portion 1c-3 facing the overlapping sheet portion 1e of the one side sheet portion 1c-1.
The hooking means 1f of the fiber hook fastener (trade name, Velcro) is provided on the overlapping surface of (1) to lock each other. The locking means shown by the broken line in the figure is attached to the inner surface.
A snap button as shown in FIG. 5 may be used as the locking means 1f.

Further, the fiber hook fastener may be used in combination with a snap button, a hook, a button and a slide fastener.

As described above, the top surface of the power supply housing is brought into contact with a support plate having a high heat resistance such as a veneer plate, and at the same time, the contact with the side surface of the power supply housing is also reduced, so that the heat resistance and heat dissipation are high.

Next, the cover 1 for the power source housing is shown in FIG.
It is possible to improve heat dissipation by using a part of it, for example, one side surface of the power supply casing 10 as shown in FIG.

Further, this power supply housing cover 1 is shown in FIG.
As shown in 6 and 6, when the power supply is used, the lower part can be tucked up to be mounted to improve heat dissipation.

The support plate may be formed of a frame, and in any case, it is preferable that the surface of the support plate is insulative so as not to cause any inconvenience in terms of electrical characteristics when the electric device is used. Further, although the above-mentioned embodiment describes the cover for the power source housing of the welding machine which is arranged indoors and outdoors, it can be applied to the dustproof and dustproof protective cover of other electric equipment such as indoor OA equipment. . In this case, the support structure placed on the top surface of the electric device can be omitted if necessary.

[0017]

According to the present invention, it is effective for waterproofing without being deformed or displaced by wind pressure. High heat resistance and heat dissipation.
There is no difficulty due to protrusions on the side of the housing when loading and unloading, and no large space is required for storage. Further, it has a remarkable advantage that it can be rolled up and used, or the lower part can be tucked up and attached to improve heat dissipation. It is also effective in dustproofing.
