Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an installation leg of an air conditioner outdoor unit.

[0002]

2. Description of the Related Art When an outdoor unit of an air conditioner is installed on an outdoor level ground, wall surface or roof of a building, it is often fixed to a stand by bolts. In this case, there are several methods depending on the shape of the installation leg of the outdoor unit of the air conditioner (hereinafter referred to as the installation leg).

The following is a description of the installation leg structure of the above-described conventional air conditioner outdoor unit (hereinafter referred to as an outdoor unit) and the installation work on the stand with reference to the drawings.

FIG. 4 is a plan view and a front view showing the shape of a commercially available outdoor unit table (hereinafter referred to as a table).

FIG. 5 is a plan view and a front view showing a conventional example of the shape of a commercially available outdoor unit, and 1a shows an installation leg in which only round holes are formed.

As shown in FIG. 6, when fixing the outdoor unit shown in FIG. 5 to the mounting table of FIG. 4, the nut 2 attached to the mounting table is removed from the bolt 3 and the mounting leg 1a of the outdoor unit is rounded. It is necessary to place the bolt 3 of the mounting table so as to pass through the elongated hole 4 of the mounting table, and screw the nut 2 removed first from above onto the bolt 3. In this case, it is necessary to remove all four nuts 2 on the stand, and to simultaneously pass through the round holes in the mounting leg 1a while lifting the outdoor unit on the four bolts 3 on the stand, which requires labor and skill. However, since the outdoor unit is fixed to the mounting table having the round holes of the mounting legs with bolts and nuts, even if the nut is loosened, the outdoor unit is firmly fixed without coming off the mounting table.

FIG. 7 is a plan view and a front view showing another conventional example of the shape of a commercially available outdoor unit.
b shows a mounting leg provided with only a notch.

As shown in FIG. 8, when fixing the outdoor unit shown in FIG. 7 to the stand of FIG. 4, the nut 2 attached to the stand is loosened, and the outdoor unit is mounted in the long hole 4 of the stand. It is necessary to place the cuts of 1b so that the cuts are aligned, push the bolt nut that was loosened first to the depth of the cuts, and loosen and fix the nuts again. In this case, the work of securely pushing the bolts and nuts into the four notches and tightening them sufficiently is a simple work that does not require labor or skill, but if the nuts loosen, the bolts and nuts should be immediately removed from the installation legs. There is a risk of coming off.

Further, as shown in FIG. 9, and both conventional
Also, mounting legs for easily become deformed during installation, making it difficult to bolt nut mounting work.

[0010]

SUMMARY OF THE INVENTION In view of the above problems, the present invention allows an outdoor unit to be mounted on a stand by an easy operation without requiring labor or skill, and even if the nut is loose, the outdoor unit can be mounted on the stand. The purpose is to be firmly fixed without further coming off. Moreover, it is intended to prevent deformation of the legs.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a notch for the mounting foot fixing bolts and nuts of a mounting leg, and a diaphragm for preventing the loosening from coming off. It is a thing. Further, diaphragms are provided on the left and right sides of the cut to prevent deformation of the legs.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Since the shape of the mounting location of the bolt and nut is a cut shape and a diaphragm is provided around the mounting location, the bolt and nut for fixing the mounting base can be easily mounted, and even if the bolt and nut are loose, they cannot be easily removed. Safety can also be improved.

[0013]

EXAMPLE An example of the present embodiment will be described below with reference to FIGS.
Description will be made with reference to FIG.

FIG. 1 is a plan view and a side view showing an installation leg of an outdoor unit according to the present invention, and FIG. 2 is a plan view when the installation leg is attached to a stand.

In FIG. 2, a protrusion 5 is provided at the entrance of the cut, and the distance of the protrusion at the entrance of the cut is set to be smaller than the size of the head of the mounting nut of the stand, so that the present invention can be applied to the stand as shown in FIG. When mounting the mounting leg of No. 3, the bolt nut in the long hole of the mounting table can be loosened to allow the notch of the mounting leg to pass through, and the bolt and nut can be easily tightened after passing through the depth of the notch.
Further, even if the nut is loosened, the distance between the projections on the left and right of the inlet is smaller than the size of the head of the nut in the notch of the installation leg, so that the head of the nut hits the diaphragm and the tip of the notch cannot move from there.

Further, as shown in FIG. 3, due to the structure in which the throttle is provided around the notch, the leg bending force is prevented.

[0017]

INDUSTRIAL APPLICABILITY As described above, the present invention has the effect of enhancing the safety by facilitating the work in mounting the outdoor unit on the stand and preventing the fixed bolts and nuts from coming off easily even if they are loose. Have. Also, it has an effect of preventing deformation of the legs.
