Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a foldable and portable satellite broadcast receiving antenna device equipped with a fine elevation angle adjustment mechanism.

2. Description of the Related Art In recent years, as satellite broadcasting has become popular, various satellite broadcast receiving antennas have been put on the market. In particular, satellite broadcasting antennas are often installed and used outdoors, and when installing a satellite broadcasting antenna, generally both hexagonal bolts for fixing the elevation angle and azimuth angle of the satellite broadcasting antenna are fixed. After loosening it, I first set the approximate elevation angle using the elevation scale on the satellite antenna, then slightly tightened the hex bolt, and then adjusted the azimuth angle. The azimuth angle is set by rotating the satellite broadcasting antenna around the vertical axis and viewing the image or measuring the CN ratio. After making rough adjustments to the elevation angle and azimuth angle, tighten the hexagonal bolt for fixing a certain elevation angle again, then slowly change the elevation angle of the satellite broadcasting antenna and finely adjust the elevation angle. The satellite broadcast receiving antenna is fixed in a state where the ratio is maximum.

An example of the above-mentioned conventional satellite broadcast receiving antenna device will be described below with reference to the drawings.

FIG. 6 is a rear view of a conventional satellite broadcast receiving antenna device as seen from the rear, and FIG. 7 is a side view of the same. In FIGS. 6 and 7, the BS converter 15 is located on the back of the satellite broadcast antenna 14, the satellite broadcast antenna fixing link 16, the fixing hex bolt 17, the first pin 18, and the second pin. 19 and a satellite broadcast receiving antenna support 2o.

The operation of the satellite broadcast receiving antenna device configured as described above will be described below.

First, the satellite broadcasting antenna 14 is connected to the satellite broadcasting antenna support 2° by a first pin 18, so that the satellite broadcasting antenna 14 can be rotated in the elevation direction. The fixing link 16 of the satellite broadcasting antenna rotates around a second pin 19 attached to the satellite broadcasting antenna, and a fixing hexagonal bolt 17 passes through its elongated hole. After setting the elevation angle while rotating the satellite broadcast receiving antenna 14 about the first pin 18, the satellite broadcast receiving antenna can be fixed at a desired elevation angle by tightening the fixing hexagonal bolt 17.

Problems to be Solved by the Invention However, in the configuration shown in the above conventional example,
The elevation angle of the satellite broadcasting antenna is finely adjusted by changing the elevation angle of the satellite broadcasting antenna using friction with the fixing hex bolt slightly tightened, and the elevation angle is fixed at the point where the CN ratio is maximum. Setting up takes time and effort. Also, if you set it to -degrees, you can remove it and move it.
Further, when used as an indoor satellite broadcast receiving antenna, it is inconvenient to carry or store it to another location.

In view of the above-mentioned problems, the present invention attempts to solve the conventional problems, and provides a device that can perform coarse and fine adjustment of the elevation angle and can be folded and carried. The purpose is to

Means for Solving the Problems In order to solve the above problems, the satellite broadcasting antenna device of the present invention has telescopic rods of air compression dampers attached to the left and right sides of the BS converter provided on the rear surface of the satellite broadcasting antenna. Connect using. The rod of this air compression type damper is threaded and fitted with a reel and a nut. First links are connected to the left and right ends of the air compression damper on the body side so that both the left and right first links pass through one shaft. A second link is connected to the other ends of the left and right first links with pins. The second other ends on the left and right sides are pivotally connected to support ends provided at the lower part of the rear surface of the satellite broadcasting antenna with pins.

Function In the above configuration, to set the satellite broadcast receiving antenna to the receiving state from the stowed state, pull out the shaft connecting the first link, and the shaft or pin connected to the first link will be removed. The pneumatic damper and second link will be pulled out. The air compressor damper extends sufficiently and pulls the shaft until the first link and the second link are on a straight line. The second link has an edge to prevent the first link from rotating more than 180 degrees relative to the first link, so the first link and the second link are straight. Place the satellite dish on the bottom. In this state, the air compression damper is at its maximum extension, but as the air gradually escapes, the angle of elevation of the satellite broadcasting antenna slowly increases. Now, set the approximate elevation angle and turn the nut on the rod so that the satellite broadcasting antenna stops at that position. By turning the nut when the satellite dish is stopped, you can slowly decrease the angle of elevation against the weight of the satellite dish, or increase the angle of elevation according to the weight of the satellite dish. .

Embodiment Hereinafter, a satellite broadcast receiving antenna device according to an embodiment of the present invention will be described with reference to the drawings.

At this time, the rod 13 of the air compression damper 3 extends to the maximum,
As shown in Fig. 4, the elevation angle of the satellite broadcasting antenna 1 is at its minimum, so when the air gradually leaves,
As shown in FIG. 3, the rod 13 of the air compression damper 3 enters the interior, and the elevation angle of the satellite broadcast receiving antenna 1 increases. Next, as shown in FIG. 6, while looking at the elevation angle scale written on the rod 13, turn the nut 4 attached to the rod 13 to set the approximate elevation angle, and then set the satellite broadcast receiving antenna 1. to stop. Here, a part of the threaded part of the telescoping rod 13 is cut flat enough to allow the nut to rotate, and the flat surface is marked with an angle scale indicating the angle of elevation. Next, when the nut 4 is turned, the length of the rod 13 changes, so that the elevation angle of the satellite broadcasting antenna can be gradually changed. When folding the satellite broadcasting antenna device, move the nut 4 toward the first pin 7,
By returning the shaft 1o and retracting the rod 13 of the air compression damper 3, the satellite broadcasting antenna device can be folded as shown in FIG. 1 or 2.
