[Conventional technology]

An antenna mounting tool for mounting a parabolic reflector for receiving satellite broadcasts, a flat antenna, etc. on an antenna pole is, for example, as shown in FIG. , And insert the antenna fixture into the antenna pole 51 so that the antenna pole 51 is located in the space formed by this mount body 53, the U-shaped bolt 56 attached to it, and the presser foot 59 inserted therethrough. (Fig. 5). Then, the parabolic reflector 52 is set to a substantially desired azimuth angle, the nut 57 is temporarily tightened, and the antenna pole 51 is sandwiched between the pair of upper and lower receiving plates 58, 58 of the mount body 53 and the presser bar 59, and temporarily attached. While watching the TV image and level meter, loosen the nut 57 a little and move the parabolic reflector 52 left and right to move the nut 57 at the best position.
Had been concluded.

[Problems to be solved by the device]

However, the azimuth adjustment on the antenna pole 51 cannot be performed unless the nut 57 is loosened, so that the adjustment is performed by supporting the antenna which is going to be dropped due to the weight of the antenna. Moreover, since it is a fine adjustment, the adjustment becomes extremely troublesome and inefficient work, and the antenna may move when tightening the nut 57 at the best position, so it was necessary to set it carefully.

The present invention has been made in view of the above points, and an object of the present invention is to provide an antenna mounting tool that can easily and efficiently perform an azimuth adjustment work on an antenna pole.

[Means for Solving the Problems]

In order to achieve this object, in the antenna mounting device of the present invention, a pair of bolts projecting on both sides of the receiving metal fitting are inserted between the holding metal fittings and the nuts are screwed together, and an intermediate part is provided between the side walls of the receiving metal fittings. A base for a plurality of upper and lower U bolts, which are locked by the locking part, insert a presser foot into the tip and screw a nut, are attached to the main body, and the main body is brought into contact with the receiving bracket so as to be rotatable left and right. It comprises an azimuth angle adjusting tool having a long hole for a bolt and an antenna elevation angle adjusting tool having an antenna mounting portion and rotatably mounted on a main body.

The abutting surface portion between the receiving metal member and the main body portion may be a convex arcuate surface portion on one side and a concave arcuate surface portion on the other side, or a pair of protruding strips that abut on a generatrix of the convex arcuate surface portion.

The locking portion for locking the U bolt may be a receiving groove, and a plurality of sets of protrusions for supporting and guiding both sides of the U bolt.

[Action]

The main body 8 of the azimuth angle adjuster 3 is set on the antenna 1 by the antenna elevation angle adjuster 2 at the elevation angle of the installation area, and the space between the receiving metal fitting 5 and the holding metal fitting 6 of the pole clamp 4 and the azimuth angle adjusting tool 3 is set. When the antenna mounting tool is inserted into the antenna pole 7 so that the antenna pole 7 is located between the main body 8 and the presser foot 23 and the antenna 1 is set at a substantially desired azimuth angle, the nut 20 is fastened and the receiving metal 5 is received. The antenna pole 7 is clamped by the holding metal fitting 6, and the pole clamp 4 is firmly fixed to the antenna pole 7. As a result, the azimuth angle adjuster 3 supported by the U-bolt 21 in the receiving groove 22 of the receiving fitting 5 is held by the antenna pole 7 via the pole clamp 4. Also, the azimuth angle adjuster 3
The antenna 1 attached via the antenna elevation angle adjusting tool 2 is also held by the antenna pole 7, so that the antenna 1 does not fall by its own weight. Therefore, the azimuth angle can be adjusted by rotating the main body 8 in the left-right direction while watching the television image and the level meter without supporting the antenna 1. Also, when the adjustment of the azimuth angle is completed and the antenna 1 is fixed to the antenna pole 7 by sandwiching the receiving member 5 and the antenna pole 7 with the main body portion 8 of the azimuth angle adjuster 3 and the pressers 23, 23, The antenna 1 and the main body 8 integrated by the antenna elevation angle adjuster 2 are connected to the antenna pole 7 via the pole clamp 4.
Since the antenna 1 and the main body portion 8 are pressed against the pole clamp 4 and the nut 27 is fastened, the antenna 1 can be securely fixed to the antenna pole 7 without moving.
