Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable portable satellite broadcast receiving antenna device provided with a mechanism for finely adjusting an elevation angle.

2. Description of the Related Art In recent years, satellite broadcasting has been implemented, and various satellite broadcasting receiving antennas have been released. In particular, satellite broadcast receiving antennas are often installed outdoors and used, and in order to install the satellite broadcast receiving antenna, generally, both hexagon bolts for fixing the elevation angle and azimuth angle of the satellite broadcast receiving antenna are used. After loosening, first set the approximate elevation angle with the elevation scale attached to the satellite broadcast receiving antenna, then tighten the hex bolt slightly, and then adjust the azimuth angle. The azimuth is set while viewing the video or measuring the CN ratio while rotating the satellite broadcast receiving antenna around the vertical axis. After coarse adjustment of elevation and azimuth, tighten a little, then loosen the fixing hex bolt at a certain elevation again, slowly change the elevation of the satellite dish and fine-adjust the elevation to maximize the CN ratio. In such a state, the satellite broadcast receiving antenna is fixed.

Hereinafter, an example of the above-described conventional satellite broadcast receiving antenna device will be described with reference to the drawings. FIG. 6 is a rear view of the conventional satellite broadcast receiving antenna device as viewed from the rear, and FIG. 7 is a side view of the same. 6 and 7, a BS converter 15 is provided on the back of the satellite broadcast receiving antenna 14, and a fixing link 16, a fixing hexagon bolt 17, a first pin 18, and a second pin of the satellite broadcast receiving antenna are provided. It is attached with 19 and satellite broadcast receiving antenna support 20 and the like.

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

First, the satellite dish 14 is coupled to the satellite dish support 20 by a first pin 18;
Rotation in the elevation direction is possible. The fixing link 16 of the satellite broadcasting receiving antenna rotates around a second pin 19 attached to the satellite broadcasting receiving antenna, and a hexagonal fixing bolt 17 passes through its long hole. After setting the elevation angle while rotating the satellite broadcast receiving antenna 14 around the first pin 18, the satellite broadcast receiving antenna can be fixed at a desired elevation angle by tightening the fixing hexagonal bolt 17.

However, in the configuration shown in the above-described conventional example, the elevation angle of the satellite broadcast receiving antenna is increased while the hex bolt for fixing is slightly tightened, and the elevation angle of the satellite broadcast receiving antenna is increased by utilizing friction. Fine adjustment is made by changing the angle, and it is fixed at the point where the CN ratio becomes the maximum, so that it takes time and effort to set the elevation angle. Also, once set, it is inconvenient to remove and move it, or to use it as a satellite receiver for indoor use, carry it to another place or store it.

The present invention has been made in view of the above problems, and has been made to solve such a conventional problem, and provides a device that can perform coarse adjustment and fine adjustment of an elevation angle and that can be folded and carried. It is the purpose.

Means for Solving the Problems In order to solve the above problems, the satellite broadcast receiving antenna device of the present invention is provided with pinned telescopic rods of air compression dampers on the left and right sides of a BS converter provided on the rear surface of the satellite broadcast receiving antenna. Use with to connect. The rod of this pneumatic damper is threaded and a nut is fitted. A first link is connected to the left and right ends of the body side of the air compression damper with a single shaft so that both the left and right first links pass therethrough. A second link is connected to the other end of the left and right first links by pins. The other left and right other ends are pivotally connected to support ends provided on the lower portion of the rear surface of the satellite broadcast receiving antenna with pins.

In order to set the satellite broadcast receiving antenna from the housed state to the reception state in the above configuration, when the shaft connecting the first link is pulled out, the shaft is connected to the first link by a shaft or a pin. The pneumatic damper and the second link come out. Pull out the shaft until the air compression damper is fully extended and the first and second links are straight. The second link is the first
Are provided with anti-rotation edges so that relative rotation of 180 ° or more does not occur, so that the first and second links, which are linear, are at the bottom and the satellite broadcast receiving antenna Put. In this state, the air-compression damper is in the state of maximum extension, but since the air gradually escapes, the elevation angle of the satellite broadcast receiving antenna gradually increases. Here, the elevation angle is set to an approximate value, and the nut on the rod is turned so that the satellite broadcast receiving antenna stops at that position. When the nut is turned from the state where the satellite broadcast receiving antenna is stopped, the elevation angle can be slowly reduced against the weight of the satellite broadcast reception antenna, or the elevation angle can be increased according to the weight of the satellite broadcast reception antenna.

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