Abstract

The present invention fixes a satellite dish receiving dish antenna for receiving satellite broadcast, and the satellite broadcasting receiving antenna which can be installed by adjusting the fixed angle to the upper and lower (angle), right and left (Azimuth), rotation angle freely It is about a bracket.

In the conventional dish antenna fixing bracket structure, it is possible to adjust the installation angle (angle angle and horizontal angle) by twisting the dish antenna vertically and horizontally, but adjusting the installation angle by rotating the dish antenna relative to the center of the antenna ( Rotation angle adjustment was an impossible constraint.

Therefore, it is difficult to fix the antenna at an angle having the highest reception sensitivity, and it has to be satisfied to secure the elevation angle and the horizontal angle at an appropriate reception sensitivity.

The present invention, as shown in Figure 1, the first bracket body 4 and the second bracket body (5) fastened to the support (1) by a fixing band (2) guide pin bolt (7) and elevation angle adjusting groove And the third bracket body 10 to which the antenna 9 is fixed is rotatably configured using the guide pin bolt 12 and the rotation angle adjusting groove 13. In order to overcome the conventional problems of the satellite broadcasting reception dish antenna and the horizontal angle, as well as the angle of rotation can be easily adjusted in one bracket, it is possible to install the dish antenna in the direction having the highest reception sensitivity.

Description

Omni-directional adjustable dish antenna fixing bracket for microwave transmission and reception

The present invention is designed to fix a dish antenna for receiving microwave broadcasting and satellite broadcasting, and to fix and adjust the fixed angles up, down, left and right (Azimuth) and rotation angle freely. An antenna bracket for wave transmission and reception and satellite broadcasting reception.

Conventionally, a bracket for fixing a satellite dish receiving antenna to a building (a rooftop or an outer wall surface of a building) includes a support, a first bracket fixed to the support, and an article fixed to the first bracket to fix the dish antenna. And a second bracket and axially fix the second bracket to the first bracket with a pin, thereby allowing the dish antenna to be adjusted in the vertical direction along with the second bracket so as to adjust the elevation angle, on the other hand, the first bracket The bracket was twisted to adjust the Azimuth in the left and right directions.

The conventional dish antenna fixing bracket structure can adjust the installation angle (height and horizontal angle) by twisting the dish antenna in the vertical and horizontal directions, but adjusting the installation angle by rotating the dish antenna relative to the antenna center. One (adjustment of rotation angle) was impossible constraint.

Therefore, it is difficult to fix the antenna at an angle having the highest reception sensitivity, and it has to be satisfied to secure the elevation angle and the horizontal angle at an appropriate reception sensitivity.

The present invention overcomes these problems, so that the angle of elevation and horizontal angle of the dish antenna for satellite broadcasting, as well as the rotation angle can be easily adjusted in one bracket, so that the dish antenna can be installed in the direction having the highest reception sensitivity. do.

3 is a second operating state diagram of the present invention

The present invention, as shown in Figure 1, a fixing band (2) and fastening bolt (3) for fixing the bracket to the support (1) fixed to the building,

A first bracket body 4 fastened to the support 1 by the fixing band 2 and the fastening bolt 3;

A second bracket body 5 rotatably supported by the first bracket body 4, and

An axial bolt 6 rotatably bearing the second bracket body 5 to the first bracket body 4;

An elevation angle adjusting groove 8 formed in the guide pin bolt 7 and the second bracket body 5 for fixing the second bracket body 5 by a predetermined angle in the vertical direction about the shaft bolt 6. and,

One side is rotatably fixed to the second bracket body 5 and the other side of the third bracket body 10 is fixed to the antenna 9,

An axial bolt 11 rotatably bearing the third bracket body 10 to the second bracket body 5;

Rotation angle adjustment groove 13 formed in the guide pin bolt 12 and the second bracket body 5 for fixing the third bracket body 10 is rotated by a predetermined angle around the shaft bolt (11). It is configured by.

Referring to FIGS. 2 and 3, the operation of the dish antenna fixing bracket for omnidirectional adjustment of the present invention configured as described above will be described as follows.

First, Figure 2 is a view showing the action of rotating the antenna 9 in the horizontal direction around the support (1), or adjust the angle (angle) in the vertical direction using the bracket of the subject innovation.

In the installation of the antenna 9, the installation angle is an angle toward the satellite, corresponding to the longitude and latitude of the point where the antenna is installed, and the horizontal direction (longitude) and the vertical direction (angular angle) must be aligned. 1) Loosen the fastening bolt (3) of the fixing band (2) secured to 1) to loosen the band between the bracket and the support, and the bracket (4, 5, 10) with the antenna (9) in the 'a' direction. Rotate the bolts 3 in place and tighten them.

In this way, while the first bracket body 4 is firmly fastened by using the fastening band 2 and the bolt 3 to the support 1, the second bracket body 5 is predetermined with respect to the shaft bolt 6. Rotate in the 'b' direction to adjust the elevation angle.

That is, when the second bracket body 5 is rotated in the 'b' direction, the elevation bracket 8 is guided to the guide pin bolt 7 while the second bracket body 5 rotates about the shaft bolt 6. When the proper elevation angle is achieved, the elevation angle is adjusted by tightening the guide pin bolt 7.

When the angle of the antenna 9 in the horizontal and vertical directions is adjusted as above, the final installation angle is adjusted by rotating the antenna 9 in the 'c' direction about the center of the dish as shown in FIG. do.

This is made possible by the third bracket body 10 being rotated about the shaft bolt 11.

That is, while the rotation angle adjusting groove 13 is guided to the guide pin bolt 12, the third bracket body 10 is rotated at an appropriate angle about the shaft bolt 11, and the guide pin bolt 12 at an appropriate angle. ), The antenna 9 is firmly fixed to the third bracket body 10.

As described above, the fixing band 2 adjusts the installation angle Azimuth of the horizontal direction (a direction) of the antenna 9 fixed to the support 1, and the antenna (with the second bracket body 5) It is possible to adjust the angle of the vertical direction (b direction = elevation angle) of 9), the angle of the rotation direction (c direction) to the center of the dish of the antenna 9 with the third bracket body (10).

As described above, according to the dish antenna fixing bracket for omnidirectional transmission and reception and satellite broadcasting of the present invention, the mounting angle of the dish antenna can be freely adjusted not only up, down, left, and right but also the rotation angle of the antenna itself. There is an effect that the antenna can be installed in the direction and angle having the highest reception sensitivity.
