とになる。2. Description of the Related Art As a conventional switch suspender, FIG.
Some have the structure shown in FIGS. The hanging tool is attached to the mounting frame 5 above the upper lid 3 covering the top of the switch body 4.
The yoke 1 having a U-shaped cross section is fixed on the upper surface of the mounting frame 5 by welding, and the suspension bolt 2 is rotatably supported by a support shaft 6 inserted into both ends of the yoke 1. It was done. When the switch body 4 is suspended and fixed, with the suspension bolts 2 held in the vertical direction,
Pass the hanger plate by inserting it into the fixing target member not shown,
The switch body 4 is fixed by tightening the nut from the upper end.
The suspension bolts 2 are usually pivotally supported at the left and right ends of the yoke 1, and the length of the yoke 1 is substantially the same as the width of the mounting frame 5. Therefore, when the suspension bolt 2 is pivoted outward, the downward pivot range is widened, and the suspension bolt 2 and the free end of the hanger plate 7 rotate until the free ends of the suspension bolt 2 hit the upper lid 3.

しさがあった。As described above, if the suspension bolt 2 and the hanger plate 7 are configured to rotate outward and hit the upper lid 3, the suspension bolt 2 and the hanger plate 7 can be installed at the site. The tip of the hanger plate 7 may be repeatedly hit against the upper lid 3. As a result, the surface of the upper lid 3 may be scratched, or the coating film may peel off to expose the ground. If the scratch is left as it is, rust is generated and the life of the switch body 4 is shortened. Therefore, depending on the degree of the scratch, it is necessary to repaint and repair the switch. in this way,
In the conventional switch hanger, when operating the hanger bolt 2, the hanger bolt 2 is turned outward so that the free ends of the hanger bolt 2 and the hanger plate 7 are not hit against the upper lid 3. There was an annoyance that required careful work.

Attempted. However, even if the protection plate 12 is attached in this way, the protection plate 1 is actually mounted at the site.
2 is often removed and is not being used effectively. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to solve the problem that the upper lid of the switch is scratched by the suspension bolt and the hanger plate 7 when the switch is mounted. An object of the present invention is to provide a hanging device for a switch.

FIG. 1 is a view showing an embodiment of a switch hanger according to the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a perspective view showing the whole. In the figure, reference numeral 4 denotes a switch body, 3 denotes an upper cover, and both ends of a mounting frame 5 are fixed to both side surfaces of the switch body 4, and a central portion thereof is horizontally disposed above the upper cover 3. . A yoke 1 formed in a U-shaped cross section by a plate material is fixed to the upper surface of the mounting frame 5 by welding with the opening portion facing upward. Support shafts 6 are inserted into both ends of the yoke 1, and the suspension bolts 2 are rotatably supported by the support shafts 6. Further, the hanger plate 7 is inserted through the suspension bolt 2 and is rotatably supported by the shaft.

する。The yoke 1 is arranged such that the direction of rotation of the suspension bolt 2 is in the longitudinal direction of the mounting frame 5 (the mounting frame fixed to the switch).
(In the direction connecting the fixed ends of the mounting frame 5), so that when the free end of the suspension bolt 2 is turned outward and downward, the suspension bolt 2 Rotation is stopped by contacting the end position. When the switch body 4 is attached, the hanger plate 7 is fixed to a fixing target member such as a telephone pole (not shown) by appropriately rotating the suspension bolt 2 and vertically positioning the nut, and the nut is tightened from the upper end. Thus, the switch body 4 is supported and fixed.

It will not be attached. Therefore, in the work of mounting the switch body 4 on site, it is necessary to take care not to scratch the painted surface of the upper cover 3 with the suspension bolts 2 and the hanger plate 7, and to repair the painted surface of the upper cover 3. And workability is greatly improved.

が得られる。As described above, according to the present invention, the direction of rotation of the suspension bolt is the longitudinal direction of the mounting frame (fixed to the switch).
The yoke is fixed to the mounting frame so as to be parallel to the fixed end of the mounting frame to be fixed), and the free ends of the hanging bolt and the hanger plate are attached to the mounting frame when the hanging bolt is turned outward and downward. The free ends of the suspension bolts and the hanger plate will not be hit against the top cover of the switch body even if the suspension bolts are pivoted outward and downward due to transportation or mounting work. As a result, the workability when installing the switch on site is improved, and the protection plate, etc., which was conventionally attached, is not required, so that the cost can be reduced and the waste material after the operation is reduced. Benefits are obtained.
