Description

[Detailed Description of the Invention] This invention relates to a support device for a parabolic antenna reflector that can be used when receiving signals emitted from a broadcasting satellite or when receiving and transmitting local communication signals on the ground. .

In this type of antenna, the adjustment mechanism for adjusting the angle of attack of the parabolic antenna was complicated and expensive, and it was also heavy, making it difficult to move.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned problems and provides a support device for a parabolic antenna reflector that has a simple structure and can be easily adjusted.

The drawings showing the embodiments of the present application will be described below.

The antenna device shown in the figure consists of a stationary object A, a parabolic antenna C, and a support device B for attaching the parabolic antenna C to the stationary object A. In the fixed objects exemplified above, 3 is a hollow tubular support, 2 is a mounting base attached to the lower end of the support 3, and is for fixing to a foundation or building set on the ground 1, A through hole is provided through which a screw rod 5 for fixing is passed. 4 indicates a well-known reinforcing piece. Furthermore, if the mounting space 2 is made larger in area and heavier, the threaded rod for fixing becomes unnecessary.

Next, the parabolic antenna C will be explained.

This parabolic antenna C has a configuration called a well-known parabolic antenna. 6 is a reflecting mirror, the main body of which is molded from a synthetic resin material. For example, the material is FR
P (you can use any one such as 8M (3). Also, the front side of the antenna (the side opposite to the side marked 1 in the figure)
A known radio wave reflecting material (for example, conductive paint) is coated on the surface. The reflective surface is formed to have an area sufficient to receive radio waves from a broadcasting satellite. It may also be made of metallic material. In the reflecting mirror 6, 6' is a folded piece formed on the periphery for reinforcement. Reference numeral 8 in the parabolic antenna is a well-known primary radiator that receives the signal received by the reflecting mirror surface and sends the signal to the next stage via the converter 7.

If the parabolic antenna is used for transmission, the signal emitted from the parabolic antenna is applied to a mirror surface and used for transmission to others.

10, 10 is a horizontal support rod with base part 10' fixed to folding piece 6', 9 is a support arm with base part 9' fixed to the back side,
Converter 7 is supported by these three wires. (All of these configurations and modifications of the configuration may be configured using well-known techniques.) Furthermore, for the back surface 6a of the reflecting mirror 6, a rib 6' is provided which is made of (or integrated with) the reflecting mirror. They are arranged vertically and horizontally to prevent the surface of the reflecting mirror from being distorted. The other rib 6' is also used as a mounting part for one end of the tilting body stop in the support device B.

Next, in the support device B, U indicates a base body, which is provided with stoppers ν at the top and bottom. This Togusha pillar 3 is the base 1
1, for example, by disposing U-shaped holes above and below, with their free ends ν' penetrating the base U, and in the state shown in FIG. 3 is relatively inserted between the U-bolts, and the U-bolts ν are firmly tightened in the state shown in FIG. 2 so that they can be integrated. By loosening the U bolt a little, you can freely adjust the left and right rotation of the parabolic antenna. ν′ indicates a seat plate, which has a concave surface facing the support so that the outer periphery of the support 3 is aligned with the base H in a stable state, and this may be fixed to the base H in advance if necessary. Just leave it there. The positive part is a part constituting the base U, and is protruded toward the parabolic antenna from the left and right sides of the member to which the bolts are fastened. Further, above the member stop, a flat plate-shaped engagement piece is provided horizontally, and both members are constructed integrally. There is a pivot point 17 on the side of the member stop at the upper position.
Pivot bolts are disposed on the sides, and bolts as fasteners for preventing rocking of the tilting body are provided in a protruding manner on the lower side. The bolts constituting the pivot point 17 support the tilting body stops so as to be swingable in the direction of the parabolic antenna (in the direction of arrow A). There is a long groove 1 below the tilting body.
9, which includes a pole (20) configured as the fastening tool.
By protruding and tightening this in the state shown in FIG. 7, the swinging movement of the tilting member can be fixed. Further, a support device is horizontally fixed above the tilting body stop, and a threaded rod 6, which is exemplified as an adjustment rod, is screwed into a female screw provided thereon, and the free end δ' of the insert pin 5 is By making it possible to abut against the retaining piece 16 and rotating the knob, the distance of the support body relative to the engagement piece on the base U, that is, the reflector 6 can be adjusted to the solid line position in FIG. The tilting can be adjusted between the positions indicated by the two-dot chain line.

A female thread η' is provided on one side of the tilting body stop, through which a bolt η can be inserted to secure the tilting body stop to the rib 6' of the parabolic antenna.

When using the structure described above, the stationary object A is firmly established on any floor surface, such as the roof of a building, the roof of a house, or even on a roof, using known means. Next, the base body U is brought relatively close to the support column 3 in the state shown in FIG. 3 and joined together.

That is, the support 3 is passed between the U bolts ν and 12, and the nut opening is tightened. In this case, the gravity of the base H is supported by the support if it is brought into contact with the support piece 16 at the top 3' of the support. Nao U
When tightening the bolts, the rotation direction of the parabolic antenna is adjusted in advance. Once the base U is fixed to the support column 3 as shown in FIG. 3, the tilting body stop is then attached to the base H. Of course, both may be assembled in advance on the ground. In this assembly, the tilting body stop is attached to the base H using a bolt at the pivot point (3) so that the tilting body stop can swing downwardly in the direction of the arrow 21. Also, bolt addition is done using long groove 1.
9, the reflector 6 of the parabola antenna moves freely in the direction of the arrow 4, so this tilting is also set appropriately in advance and fixed with the pole 20. In that case, it is advisable to loosen the adjustment rod 6. Furthermore, the parabolic antenna for the tilting body stop is connected either beforehand or afterward on the ground.

Of course, electronic equipment is also connected to the converter 7. Furthermore, when making actual adjustments, the parabolic antenna can be tilted freely by loosening the bolts, so the tilting angle can be changed over a wide range. Fine adjustments are then made by turning the adjustment rod 6 using the knob U. After this adjustment is completed, the parabolic antenna device is firmly fixed to the fixed object by tightening the pole (20) again.The above tilt angle allows reception from anywhere from the north to the south of Japan. Although the parabolic antenna is designed to tilt within a range of approximately 3j°, it may be configured to allow for further tilting.As described above, in this invention, the fixed object A is The attached parabolic antenna B is attached to the stationary object A via a support device C which is pivotally connected above the stationary object and swingable below, so that it can be attached to the stationary object A, for example. Even if it is desired to change the angle of attack of the parabolic antenna in order to make it face the parabolic antenna, there is an advantage that the purpose can be achieved by swinging and displacing the tilting body in the support device C.

Furthermore, when changing the tilting angle of the reflector 6, the reflector 6 can be tilted largely by simply loosening the bolts.

That is, since the free end 6' of the adjusting rod 5 is only brought into contact with the retaining piece 16, it is easy to lift the lower end of the reflecting mirror 6 to the right in the figure. After adjusting the tilting angle over a large range as described above, by operating the adjusting rod 5 and applying its free end 5' to the retaining piece 16, fine adjustments can be made and the tilting angle after adjustment can be maintained. becomes possible. After doing this, it is possible to employ an extremely simple operation in which the tilting angle of the satellite parabolic antenna is fixed by simply tightening the pole 20.
