Description

[Detailed explanation of the invention] The second invention, for example, receives SHF radio waves and converts them into UHF.
This invention relates to a device for attaching a converter with an antenna to a pole, which converts the radio waves into radio waves and supplies them to the television.

Conventional such devices include those shown in FIGS. 1 and 2.

That is, 2 is an angle adjuster, which has a side wall 4 and an upper wall 6 and a lower wall 8 protruding from the center of the upper edge and lower edge of this side wall.

This side wall 4 has a center 9 of this side wall as shown in FIG.
1 symmetrically along a circle with a given diameter drawn as the center of the circle
A pair of arc-shaped elongated holes 10, 10 are bored.

Furthermore, inside the long holes 10, 10 of this side wall 4,
A pair of U-bolt insertion holes 12, 12 are bored so as to be located on a horizontal line passing through the center of this side wall 4.

Recessed portions 14 and 14 are formed at the side edges of the earthen wall 6 and the lower wall 8, respectively.

This recess 14.14 abuts against the column 15.

16 is a U-bolt, and its curved portion 18 is shown in FIG.
The leg portion 20 is positioned on the opposite side of the upper wall 6 and the lower wall 8.
．． 20 are inserted into the U bolt insertion holes 12, 12.

The leg portion 20.20 has a pressing member 22 and a nut 24°24.
are inserted therethrough, and the angle adjuster 4 is pressed and fixed to the support column 15 by these.

26 is a coupling part, which is connected to 1 of the outer shell 27 of the converter with antenna.
They are protruded from the side wall portion at a distance equal to the diameter of the circle mentioned above.

The coupling portions 26, 26 are short cylindrical, and are each provided with a threaded hole.

Bolts 28 and 28 are screwed into the screw holes through the long holes 10, 10 of the angle adjuster 4, so that the converter is attached to the support column 15 via the angle adjuster 4.

The converter has a parabolic antenna (not shown) mechanically attached to a flange-like mounting portion 30, converts SHF radio waves received by the antenna into UHF radio waves, and supplies the UHF radio waves to a television receiver.

Note that 32 is a connector for connecting an output cable, 34 is a gain adjustment knob, and 35 is a protrusion formed by an internal structure.

In this type of converter with an antenna, it is necessary to adjust the angle at which the antenna is attached to the support column 15 in order to direct the antenna toward the transmitting side.

The mounting angle was adjusted by sliding the converter shell along the elongated holes 10, with the converter shell 27 attached to the support column 15 via this mounting device.

However, in this angle adjustment, one position of 28.28 becomes the initial center of rotation, and then the other position becomes the center of rotation, so it is important to adjust the angle smoothly. could not.

One of the bolts 28.28 becomes the center of rotation, and then when trying to prevent the other from becoming the center of rotation, the bolt 2
8.28 needs to be loosened considerably.

In this case, the length (Llo) is longer than the diameter of 28.28.
, it is common to increase the width of 10, so Pol)
28. When 28 was loosened, the outer shell 27 slipped down and got wedged in the curved parts of the elongated holes 10, 10, making it impossible to smoothly adjust the angle.

In order to smoothly adjust the angle, it is desirable to rotate around the center of the circle through which the elongated holes 10, 10 pass (point 9 in FIG. 2).

Conventionally, as such, there was a
There is something disclosed in the issue.

However, this is a rectangular frame with the antenna mounting rod inserted,
The long side surfaces of the rectangular frame through which the support rod is inserted are brought into surface contact with each other, and both long side surfaces are pivoted with rivets, and this is used as the center of rotation.

Therefore, if this is applied to the converter shown in FIGS. 1 and 2, the side wall 4 and the outer shell 27 are always connected with rivets, and the U bolts 16 protrude to the side of the converter, causing There was a problem with getting in the way.

Also, the angle adjuster 2 and the outer shell 2 are not connected by using rivets.
Moreover, the distance between the angle adjuster 2 and the outer shell 27 is quite narrow, and a special tool is required to make this connection.

The object of this invention is to provide a device for attaching a converter with an antenna to a support column, which allows the angle to be adjusted easily and smoothly without interfering with packaging.

This invention will be explained below based on an embodiment shown in FIG.

This mounting device is the same as the conventional mounting device shown in FIGS. 1 and 2, with new protrusions 36 and 36 added thereto.

Therefore, the same reference numerals are given to the same parts as in the prior art, and the description thereof will be omitted.

The protrusion 36.36 protrudes from the intermediate portion of the two joint parts 26.26 so as to rotatably sandwich the center of the curved part 18 of the U-bolt 16 when the angle adjuster 4 is attached to the joint part 26.26. has been done.

When the angle is adjusted using the mounting device configured in this way, the outer shell 27 of the converter comes into contact with the center of the curved portion 18 of the U-bolt 16 and one of the protrusions 36, 36, and rotates around this. It rotates smoothly and allows smooth angle adjustment.

This is particularly effective when finely adjusting the angle.

According to this invention, the curved portion 18 of the U-bolt 16 is sandwiched by the protrusions 36, 36 near the center 9 of the circle through which the elongated holes 10, 10 pass, and this is used as the center of rotation.

Therefore, the angle adjuster 2 and the outer shell 27 of the converter are
The angle adjuster 2 and the outer shell 27 can be separated by removing the pin 28.28 and can be packed separately.

Further, the protrusions 36 and 36 can be integrally molded with the outer shell 27, and it is only necessary to sandwich the curved part 18 of the U-bolt 16, which is originally used for attaching the angle adjuster 2 to the column, between the protrusions 36 and 36. This eliminates the need for troublesome work.

Furthermore, even if you loosen the pole 28.28 in order to adjust the angle, the curved part 18 of the U bolt 16 will not fit into the protrusion 36.3.
6, the outer shell 27 will not slip downward.
