Description

[Brief explanation of drawings]

Fig. 1 is a perspective view of a specific embodiment of the present invention, Fig. 2 is a perspective view of a U-shaped metal fitting used in Fig. 1, and Fig. 3 is a perspective view of a specific embodiment of the present invention.
The figure is a perspective view of a structure using a holding piece as a temporary fixing means in another embodiment, and FIG. 4 is still another embodiment,
As a temporary fixing means, a positioning plate is hung down and fixed to the base plate at the bottom end of the antenna mounting column, a horizontal long hole is drilled at the top end of the column, and a locking rod is inserted through there and fitted into the positioning plate. Perspective view of the structure, No. 5
The figure is a perspective view of a conventional example in which a parabolic reflector attachment device is attached to a support column, Figure 6 is an enlarged perspective view of the azimuth adjustment mechanism shown in Figure 5, and Figure 7 is another conventional example in which a parabolic reflector attachment device is attached to a support column. Fig. 8 is a perspective view of the parabolic antenna attached to the parabolic reflector mounting device shown in Fig. 7, Fig. 9 is a side view of Fig. 8, and Fig. 10 shows the strut and mounting column shown in Fig. 9.

Claims (1)

[Claims for Utility Model Registration] (1) A parabolic reflector mounting device in which a parabolic reflector is provided on the upper end of the mounting column in a freely undulating manner is installed on a support plate fixed to the upper end surface of the upright column, and In a parabolic antenna device in which a substrate fixed to the lower end face is placed in contact with the support plate, the substrate and the support plate are rotatably provided, and are screwed together with bolts and nuts. 1. A parabolic antenna device comprising a temporary fixing mechanism for maintaining surface contact between a substrate and a support plate before screwing with bolts and nuts. (2) The temporary fixing mechanism has a U-shaped cross section with horizontal upper and lower pieces connected to each other and a vertical base piece, and the upper and lower pieces are set at intervals that sandwich the stacked support plate and substrate. ,
2. The parabolic antenna device according to claim 1, wherein the upper piece and the lower piece are U-shaped metal fittings each having a through hole for a bolt. (3) The parabolic antenna device according to claim 1, wherein the temporary fixing mechanism has a structure in which holding pieces for sandwiching the support plate are provided on the lower surface of the substrate. (4) The temporary fixing mechanism fixes the positioning plate with holes drilled on the bottom surface of the board in a hanging manner, and when the positioning plate is housed at the upper end of the column, a horizontal hole is formed on the side wall of the column opposite to the hole in the positioning plate. 2. The parabolic antenna device according to claim 1, wherein the parabolic antenna device has a structure in which an elongated hole is bored and a locking rod is inserted into the elongated hole and fitted into a hole in a positioning plate.
