Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an antenna direction adjustment jig for determining the antenna direction when a mobile antenna, for example, a radio device with a parabolic antenna, is used.

2. Description of the Related Art Portable microwave wireless communication devices for short-range communication, as shown in FIG. 3, which can be used indoors or outdoors, have been used in the past. As shown in the figure, this device has a parabolic antenna 1 attached to a radio housing 2, and when in use, it is necessary to accurately point the parabolic antenna in the direction of the communication partner.

[Conventional technology]

In the conventional method of determining the direction of a parabolic antenna of a wireless communication device as described above, a small hole 3 is provided in the antenna 1 as shown in FIG. 3, and the direction of the antenna is adjusted by looking through the small hole 3 at the other party.

[Problem that the invention attempts to solve]

In the case of the above method, the problem is that it is impossible to find the pinpoint, since the target is only viewed through a small hole in the antenna, so the general direction can be determined, but it is impossible to find the pinpoint, and it cannot be applied to antennas with radomes. It was hot.

[Means for solving problems]

The present invention provides an antenna direction adjustment jig that eliminates the above-mentioned conventional problems, and its means include:
A plate that is removably attached to the housing, an aiming tube provided on the plate parallel to the directional direction of the antenna fixed to the housing and so that the field of view is not obstructed by the antenna, and This is accomplished by an antenna direction adjustment jig characterized in that the antenna direction adjustment jig is comprised of a bolt with a needle-like tip provided so that the tip is located at the center of the cylindrical cross section.

[Effect]

The above-mentioned antenna direction adjustment jig determines the general direction of the antenna by looking through the communication partner's device from a aiming tube installed parallel to the direction of the antenna, and also determines the general direction of the antenna by looking through the aiming tube installed parallel to the direction of the antenna. By aligning three points on the tip and the other device in a straight line, the precise direction can be determined.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention, in which a is a plan view, b is a side view, and c is a partially enlarged view of diagram b.

As shown in the figure, this embodiment includes a plate 10 that can be detachably attached to the housing of a wireless device, a cylinder 11 for aiming,
The bolt 12 has a needle-like tip, and the plate 10 has both ends bent at right angles in opposite directions.
Furthermore, an L-shaped metal fitting 13 is provided opposite to one of the bent portions 10a, and the L-shaped metal fitting 13 has a spring 1.
A press fitting 16 having a press plate 15 urged toward the bent portion 10a by the press member 4 is provided. Further, the cylinder 11 is fixed along the other bent portion 10a of the plate 10 near both ends thereof by bolts 12. This bolt 12 has a needle-shaped tip, and is formed so that when the cylinder 11 is fixed to the plate 10, the tip 12a is located exactly at the center of the cross section of the cylinder 11, as shown in Figure c. Note that board 1
Rubber plates 17 for anti-slip and housing protection are provided on opposing surfaces of the bent portion 10a of 0 and the pressing plate 15, respectively.
18 is affixed. Also, the bent portion 10 of the plate 10
b must be parallel to the orientation direction of the parabolic antenna of the device to be adjusted, and must be located at such a position that when looking into the cylinder 11 from behind, the field of view is not obstructed by the parabolic antenna. Also, bolt 1 of plate 10
By making the hole through which 2 passes a blank hole and using the spring washer 19, it is possible to make pinpoint adjustments in the vertical and horizontal directions in advance.

This embodiment constructed as described above is used as shown in FIG. That is, the plate 10 and the pressing plate 15
The housing 2 of the device 20 whose antenna direction is to be adjusted with
1 and is attached to the housing 21 by the force of the spring 14. In this state, look from the rear of the cylinder 11, and place the device 20 in such a way that the other party's device is within its field of view.
Adjust the direction of and then tighten the two bolts 1 inside the cylinder.
Fine adjustment is made so that the tip 12a of the device 2 and the other device are aligned in a straight line.

By adjusting in this manner, the parabolic antenna 22 is accurately directed to the other party's device.

Note that the shape of the cylinder is not limited to a circle.

[Effect of idea]

As explained above, according to the present invention, the accurate direction of the antenna can be easily determined using the cylinder and the two bolts each having a needle-like tip, which are provided parallel to the direction of antenna orientation. Furthermore, the jig of the present invention can be easily attached to and detached from the device, and can also be applied to antennas with radomes.
