Description

[Detailed Description of the Invention] The present invention relates to a portable antenna installation device.

This invention provides a portable antenna installation device that can be used to check the reception status in advance in areas where satellite broadcasting is available, or to receive reception by a mobile model.It can be folded freely and transported anywhere. In addition, the antenna is extremely easy to install and set up, and in addition, a reflector for a parapolar antenna of any size can be attached.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in FIGS. 1 to 5 attached hereto. The folding tripod 1 has a central vertical column 3 fitted onto a support tube 2 from above and rotatably engaged with the support tube 2, and three extendable support legs 4 are provided on the outer periphery of the support tube 2 so as to be openable and closable.
A horizontal support shaft 29 is orthogonally fixed to the upper part of the central vertical column 3, and the adjustment body 5 is rotatably mounted thereon. The adjustment body 5 is horizontally rotatable around the central vertical column 3, and the adjustment body 5 is fixed to the central vertical column 3 by:
This is done by screwing the fixing screw handle 6 attached to the fastening flange of the support tube 2. The adjustment body 5 is rotated up and down around both ends of the support shaft 29, and is fixed by tightening fixing screw handles 9, 10 screwed onto the vertical side walls 7, 8 at both ends of the support shaft 29.
Fixed at 9.

The front side of the adjustment body 5 forms a substrate 11 at right angles to the vertical side walls 7,8. Attachment bolts 12 with knobs are screwed into the four corners of this board 11 from the back side toward the front surface, and an engagement pin 13 is provided in the center of the surface to protrude toward the front.

The mounting plate 14 is set according to the size of the reflector 15, and has mounting holes 17 in its four corners for inserting bolts 16 that are screwed into the seats on the back side of the reflector 15, and holes in the center. The mounting bolt 12 on the back side
A housing-shaped mounting piece 20 is formed which has a screw hole 18 for screwing the holder and an engaging hole 19 for inserting the engaging pin 13. This is an antenna device in which a mounting plate 14 is fixed to a reflecting mirror 15 by fitting bolts 16 into its mounting holes 17 and tightening the bolts 16. After the engagement pin 13 of the antenna installation device is engaged with the engagement hole 19, the mounting bolt 12 is screwed into the screw hole 18 to fix the reflecting mirror 15 to the tripod 1. Moreover, when removing it, it is sufficient to simply loosen the mounting bolt 12. Note that the size and the position of the mounting hole 17 of the mounting plate 14 are set according to the size of the reflector 15 and the position of the seat, but the screw hole 18 and the engagement hole 19 of the mounting piece 220 are The settings are the same to match those of No. 11.

A leveling level 21 is attached to the horizontal portion of the upper end surface of the central vertical column 3, and one vertical side wall 7 of the adjustment body 5 is provided with a swing-down measuring device 22 capable of measuring the antenna radio wave arrival angle. The swing-down measuring device 22 consists of a measuring needle 23 and a measuring plate 24, and the measuring plate 24 is fixed to the vertical side wall 7 of the adjusting body 5 in a fan shape and has an angle scale 25 engraved on its outer periphery. The measuring needle 23 is provided at the center point of the scale 25 in a swinging shape that always points in the downward direction. When the adjusting body 5, that is, the reflecting mirror 15 is raised or lowered, the measuring needle 23 sets the angle scale 25 so as to indicate its elevation angle. This angle scale 25 immediately indicates the elevation angle at which the radio waves arrive, and when the reflector 15 is an offset parabolic reflector, it is difficult to set a standard for the elevation angle direction that indicates the direction in which the radio waves arrive. Useful.

Next, the operation of the above portable antenna installation device will be described. When installing this device at an arbitrary location, open and extend the support leg 4 of the tripod 1, and then engage the mounting plate 14 provided on the reflector 15 with the engagement pin 13 of the base plate 11 through the engagement hole 19. Then, screw the mounting bolt 12 into the screw hole 18 to attach the reflecting mirror 15 to the tripod 1. Subsequently, the tripod 1 is held horizontally using the horizontal level 21 on the upper end surface of the central vertical column 3 of the tripod 1. Next, the user grasps the fixing screw handle 6 and sets the azimuth of the reflecting mirror 15 using a magnet or the like, and then tightens the fixing screw handle 6 to fix the azimuth. Subsequently, the elevation angle of the reflector 15 is set using the handle 9, and the handles 9 and 10 are tightened to fix it. At this time, the elevation angle of the reflector 15 is determined by the measuring needle 2 of the swing-down measuring device 22.
3 is the value shown on the angle scale 25 of the measuring plate 24. When removing and transporting this device, use the reflector 15.
It can be easily transported by loosening and removing the mounting bolts 12 and contracting and closing the supporting legs 4. In addition, numeral 26 is a support arm, 27 is a converter,
28 is an antenna primary radiator.

As mentioned above, the present invention is a folding structure in which a horizontal support shaft is orthogonally fixed to the upper part of the central vertical pillar, and an adjustment body can be horizontally rotated, undulated, and fixed to the central vertical pillar and the support shaft. It is a type tripod,
An engaging pin is provided protruding from the front surface of the adjustment body, and a mounting bolt is screwed therein. An engaging hole for engaging the engaging pin is bored on the back surface of the antenna reflector, and a screw hole is carved into which the mounting bolt is screwed. A mounting plate is provided, a reflector for the antenna is detachably attached to the front of the adjustment body, a leveling level is attached to the horizontal part of the upper end surface of the central vertical column, and a swing plate is installed on the vertical side wall of the adjustment body to measure the elevation angle at which the antenna radio waves arrive. This is a portable antenna installation device that is equipped with a lowering type side fixture, and can be freely folded and transported anywhere.In addition, it is extremely easy to install and set up the antenna, and it can be installed in any size. Even a reflector can be attached by aligning the screw holes of the mounting plate with the mounting bolts of the tripod. An engaging pin is provided protruding from the front surface of the adjustment body, and a mounting bolt is screwed therein. An engaging hole for engaging the engaging pin is bored on the back surface of the antenna reflector, and a screw hole is carved into which the mounting bolt is screwed. A mounting plate is provided, and the antenna reflector can be detached from the front of the adjustment body.
Even for reflectors with sharp directional characteristics such as offset parabolic antennas, the angle of the back mounting plate is constant and flat, making it easy to attach and position the reflector to the adjustment body even for large antenna reflectors. It can be done easily and reliably.
