[Embodiment 2]
4 is a perspective view of the periphery of a suspension fitting of an air conditioner installation apparatus according to Embodiment 2 of the present invention, FIG. 5 is a bottom view of FIG. 4, and FIG. 6 is a perspective view of a receiving fitting and a locking fitting in FIG. It is. The same parts as those in the first embodiment are denoted by the same reference numerals.
This embodiment is provided with a locking means for preventing the position adjusting screw 10 that adjusts the position of the air conditioner provided on the metal fitting 5 of the main body 1 of the first embodiment from being loosened. .

  In the present embodiment, the receiving metal 5a constitutes a locking means, so that one end of the horizontal piece in the width direction is bent in an L shape downward in the figure, and a screw insertion hole is formed in the horizontal part parallel to the horizontal piece. The attachment portion 7 having 8 is formed.

  Further, the locking metal fitting 11 constituting the locking means is formed in a substantially S shape, and has a fixing portion 11a including a first horizontal portion having a screw insertion hole 12 and fixed to the mounting portion 7 of the receiving metal fitting 5a. The locking portion 13 is provided in the second horizontal portion 11b above and is formed in a shape (substantially pentagonal) corresponding to the shape of the head (hexagon) of the position adjusting screw 10 and opens to the tip portion. It has become.

  In the present embodiment configured as described above, when the position adjustment of the main body 1 is completed by the position adjusting screw 10 provided on the receiving metal fitting 5a, the locking portion 13 of the locking metal fitting 11 is connected to the position adjusting screw 10. The head is fitted to the head from below, and the fixing portion 11a is fixed to the mounting portion 7 of the metal fitting 5a with a screw. Thereby, the position adjusting screw 10 is prevented from rotating. In this case, since the side edge of the fixing portion 11a of the locking metal fitting 11 is in contact with the vertical piece of the receiving metal fitting 5a, the locking metal fitting 11 itself does not rotate.

FIG. 7 shows another example of the loosening prevention metal fitting 11 of the present embodiment. In this example, as shown in FIG. 8, the locking portion provided on the second horizontal piece 11b of the loosening prevention metal fitting 11 is shown. 13a is formed in a substantially U shape corresponding to the shape (hexagon) of the head of the position adjusting screw 10, and the inner peripheral surface thereof is formed in a sawtooth shape.
In this example as well, the same operation and effect as the locking metal fitting 11 of FIG. 6 can be obtained. However, since the locking portion 13a is formed in a sawtooth shape, it is possible to prevent the locking regardless of the tightening position of the position adjusting screw 10. It can be performed.

  According to the present embodiment, after adjusting the position of the main body of the air conditioner, the locking metal fitting 13 (or 13a) provided integrally with the receiving metal fitting 5a is locked to the head of the position adjusting screw 10. Thus, since the position adjusting screw 10 is prevented from loosening (rotating), the air conditioner can be installed and maintained more stably and reliably.
