【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. The configuration of the satellite broadcast receiving antenna is as shown in the side view shown in Figure 1. Na 1 mainly consists of a reflecting mirror surface 2, a primary radiator 3, and various mounting materials 4. The reflecting mirror surface 2 receives radio waves from the broadcasting satellite and reflects them intensively toward the primary radiator 3. The primary radiator 3 is installed at the focal point to collect the radio waves of the broadcasting satellite, and the It functions to convert circularly polarized waves from a satellite into linearly polarized waves, and the mounting material 4 converts the reflecting mirror surface 2 into It is fixed to a locking tool (hereinafter referred to as the pole support 5) for attaching the satellite broadcasting antenna 1. When fixed, the reflecting mirror surface 2 is initially set in the direction of the broadcasting satellite. It is necessary to ensure that the elevation and azimuth angles that have been set do not change.

[0007] The device for explaining the present invention is shown in a perspective view of the main part shown in FIG. A schematic cross-section having first constricted surfaces 8 that are supported at the center from the back side and that face each other on both sides of the opening. A first constriction surface 8 is provided with a fulcrum hole 7 forming a support part for adjusting the elevation angle on both sides of the concave shape. Each of them is provided with an arc-shaped elongated hole 9 whose fulcrum is the support part constituting the elevation adjustment part. Ru. The mounting member 10 that holds the pole support 5 has a cross section approximately C that fits into the pole support 5. A second narrowing surface 11 is provided opposite to both sides of the C-shaped opening, and both sides of the C-shaped part A locked member that is connected to the fulcrum hole 7 (for example, a hexagonal nut, a welded nut, or a built-in nut etc.) 12, while a through hole in each second constriction surface 11 engages with the elongated hole 9. Holes 15 are respectively drilled. Then, the mounting member 10 is attached to the inside of the base member 6. There is.

[0008] In the above configuration, the state in which the satellite broadcast receiving antenna is mounted on the pole support is shown in Figure 2. As shown in the main part sectional view shown in (b), the C-shaped portion of the mounting member 10 is attached to the pole support 5. Insert the hole into the hole to prevent the satellite broadcasting antenna 1 from moving downward from the pole support 5. The first fastening member 13 made of a bolt or the like is connected from the elongated hole 9 to the through hole of each second narrowed surface 11. 15 and into the opposing elongated hole 9, and the tip of the first fastening member 13 is covered with a nut or the like. While screwing the locking member 12, the first narrowing surface 8 and the second narrowing surface 11 are lightened. The first constriction surface 8 and the second constriction surface 11 are compressed by the same clamping. By temporarily fixing the pole support 5 inside the C-shaped part, the satellite broadcasting reception antenna can be installed. 1 can be temporarily fixed to the pole support 5, and the second fastening member 14 can be inserted into each fulcrum hole 7. Then, they are temporarily screwed onto each of the locked members 12 provided on the mounting member 10.

[0009] After that, the reflective mirror surface 2 constituting the satellite broadcast receiving antenna 1 is placed in the direction of the broadcast satellite. When fixing to the pole support 5, adjust the azimuth and elevation to align the reflective mirror surface 2 with the direction of the broadcasting satellite. The satellite broadcast receiving antenna 1 is fixed at a good position by adjusting the angle. Therefore, to adjust the azimuth angle, use the satellite broadcasting antenna 1 temporarily fixed to the pole support 5. Rotate horizontally to point the reflective mirror surface 2 in the azimuth direction of the broadcasting satellite, and roughly align the reflective mirror surface 2. 2 faces the azimuth of the broadcasting satellite, the first fastening portion between the base member 6 and the mounting member 10 Tighten the temporary fixing part with material 13. Next, to adjust the elevation angle, leave the temporary fixation to the pole support 5 as is, and then adjust the base member 6. A support portion is formed within the range of the elongated hole 9 provided in the first constriction surface 8 that constitutes the elevation adjustment portion of the With the portion of each second fastening member 14 as a fulcrum, the reflecting mirror surface 2 is adjusted to the elevation angle of the broadcast satellite While moving up and down in the direction, adjust the elevation angle to a predetermined angle so that the reflecting mirror surface 2 is approximately at the elevation angle of the broadcasting satellite. The first fastening member 13 and the second fastening member 14 are temporarily fixed to the pole support 5 at the appropriate locations. Temporarily tighten each of them again. Then, the above-mentioned azimuth angle adjustment and elevation angle adjustment are repeated until the reflecting mirror surface 2 is adjusted to a predetermined value. Once the azimuth and elevation angles are determined, the temporarily fixed second fastening members 14 and By firmly fixing the first fastening member 13, the satellite broadcast receiving antenna 1 satellite broadcasting to the pole support 5 by a pair of the first fastening member 13 and the locked member 12. The receiving antenna 1 can be fixed. During after-sales service, the pole support can be fixed by loosening each fixed part. You can remove the satellite broadcasting antenna 1 from 5, and adjust the azimuth and elevation again. It is possible to redo the angle adjustment. In addition, when adjusting the azimuth angle and elevation angle mentioned above, it is recommended to use the specified measuring device. Optimally, use a real television receiver to receive satellite broadcasts and receive Even if you make adjustments while visually checking the image, it may not be possible to make good adjustments as a general image. It is something that

0010 Note that by providing an elevation scale 16 near the elongated hole 9 of the first constriction surface 8, One that allows the reflective mirror surface 2 to be easily aligned to a predetermined angle when adjusting the elevation angle. It is. Furthermore, the arc-shaped elongated hole 9 drilled in the first constriction surface 8 is replaced with a through hole 15, An elevation angle scale 17 is provided near the through hole 15, and the through hole 16 of each first constriction surface 11 Even if the hole 9 is replaced with an arc-shaped elongated hole 9, the above-mentioned configuration is still valid. Furthermore, the materials used for the base member 6 and the mounting member 10 should be treated with anti-rust treatment such as plating. It is formed from a spring steel plate or a stainless steel plate for springs.
