Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole mounting member for mounting a cable laying member such as a support metal of an underground power cable laying device to a pole, and more particularly, to a function of allowing the member itself to rotate freely. The present invention relates to the provision of a rotary mounting device including a part.

[0002]

2. Description of the Related Art FIG. 2 shows an example of mounting of a conventional underground power cable laying pole mountable mounting bracket. The mounting members are a main body side fitting 1 and a presser fitting connected to the receiving bracket side. The metal fittings 1 and 2 are formed in a half-cylindrical cylindrical shape surrounding the pole 4, and both ends of the presser fitting 2 are fastened to the metal fitting 1 on the main body side with bolts 3 and nuts 3 c, so that the pole can be fixed to the pole. A mounting fixation is achieved.

In the pole mounting member having such a configuration, it is necessary to completely remove or insert and assemble the bolt 3 and the nut 3c from the hardware 1 and 2 at the time of disassembly and assembly.

[0004]

As described above, in the conventional cable pole mounting member shown in FIG. 2, when the pole is mounted, the pole is surrounded by fitting the presser foot 2 to the main body side metal piece 1 which is half-split. , Pass the bolt 3 between the metal fittings 1 and 2,
Fastening with nut 3c, while disassembling, bolt 3
And the nut 3c are removed once, and the presser foot 2 and the main body side hardware 1 are completely disassembled. This requires man-hours for disassembly and assembly, and also causes the bolt 3 and the nut 3c to be completely detached and lost. There was a problem.

Accordingly, an object of the present invention is to provide a pivot mounting device for a pole mounting member which can solve the problems of the prior art described above, that is, the problems of disassembling and assembling steps and the loss of bolts and nuts at once. To provide.

[0006]

The means provided by the present invention comprises a metal fitting on the main body side and a presser fitting provided on the cable laying member side, and these fittings form a half-split cylindrical shape having a shape surrounding the pole. At one end, the holding member is pivotally connected to the body-side metal member by a hinge, and one end of a crank bolt is rotatable between the other end of the holding member and the body-side metal member, and the other end. Consists of a rotary mounting device provided so as to be detachable.

[0007] One end of the crank bolt is rotatably pivotally connected to the presser foot via a pin, and the other end of the crank bolt is passed through a cutout slot provided at an end of the main body side hardware, and tightened. Good to serve.

[0008]

FIG. 1 shows an embodiment of a pivot mounting device for a pole mounting member according to the present invention.

As shown in the drawing, the apparatus of this embodiment comprises a mounting member for mounting an underground power cable arranging universal receiving bracket to the pole 4, and includes a main body side fitting 1 and a presser fitting 2 connected to the receiving bracket. The metal body 1 and 2 form a half-cylindrical tube surrounding the pole 4.

The presser fitting 2 is pivotally attached to the main body side fitting 1 at one end by a hinge 3a at one end thereof, so that it can rotate about 120 degrees with respect to the main body side fitting 1 as shown in the drawing; Is done. Due to the connection of the hinge 3a, the hardwares 1 and 2 can be handled as an integral body.

At the other end of the presser foot 2, a crank bolt 3
b is rotatably mounted. That is, presser foot 2
Two pin support plates 2a are provided in parallel outside the other end of the
One end (base side) of the crank bolt 3b is made to penetrate the pin 2b passed through the pin support plate 2a,
a and the pin 2b and / or the pin 2b and the crank bolt 3b are rotatably supported at the pin penetrating portion, so that the crank bolt 3b is rotatably (rotatably) supported with the pin 2b as a rotation axis as illustrated. You. Since the crank bolt 3b is pin-supported by the presser fitting 2 in this manner, the crank bolt 3b can be handled as an integral body together with the hardware 1 and 2.

A cut-out slot 1a is formed at the end of the main body side bracket 1 with respect to the crank bolt 3b. A similar notched slot is also formed at the end of the presser foot 2.

According to the rotary mounting device of the present embodiment configured as described above, the crank bolt 3b and the presser foot 2 are
As shown by the thin line in FIG.
Thus, the main body-side metal piece 1 whose mounting surface side is opened is applied to the side surface of the pole 4, and the presser metal piece 2 is turned so as to face the main body-side metal body 1 (the state of the solid line), and is attached to the side surface of the pole 4. At the same time, the crank bolt 3b in the rotating state (the state of the thin line) is turned to the upright state (the state of the solid line), and the bolt shaft is inserted into the notch slot 1a of the main body side metal from the side. By screwing the nut 3c from the outside of the main body side hardware 1 to the crank bolt 3b passed through the main body side hardware 1 in this manner,
The main body side hardware 1 and the presser foot 2 are tightened up in a direction in which opposing end portions approach each other with the hinge 3a as a fulcrum, so that the main body side hardware 1 and the presser foot 2 are attached and fixed to the pole 4.

At the time of disassembly, the nut 3c is simply loosened (it is not necessary to remove it), the crank bolt 3b is tilted to be separated from the metal fitting 1 on the main body side, and
Can be detached from the pawl 4 by turning it outward.

As described above, in the apparatus for pivotally mounting the pole mounting member of this embodiment, the presser fitting 2 is formed in series with the main body side hardware 1 via the hinge 3a, and the crank bolt 3b And the nut 3c can also be screwed onto the crank bolt 3b, so that all the parts are integrated, so that the bolt and nut fastening and mounting structure is one-touch. With a fastening structure, assembly and disassembly are almost one-touch and workability is greatly improved. Also, since there is no detachment of parts or assembly of other parts, there is no need to manage members during assembly, and there is no loss of bolts and nuts during disassembly and assembly. Further, since only one bolt fastening point is required, the number of assembling and disassembling steps can be reduced. For example, the efficiency of the work of assembling and disassembling can be improved, and the effect can be said to be great.

[0016]

As described above, according to the present invention, there is provided a pivot mounting device for a pole mounting member, which can solve the problems of disassembly and assembly steps and the loss of bolts and nuts at once. The initial task is to be able to achieve the objectives and have high practical value.
