Description

[Detailed description of the invention] The present invention is an antenna reflector that supports a reflector that constitutes the reflecting surface of a communication antenna, and allows the position of the reflector to be easily and precisely adjusted from the reflecting surface side. Relating to a support device.

The reflector support device for communications antennas is installed on the back side of the reflector to avoid diffuse reflection on the reflective surface, but since the antenna reflective surface requires high precision due to the electrical conditions, the vertical direction of the reflector is The mounting position must be adjusted precisely and stably, and since the adjustment is performed while observing, it is necessary that this adjustment work can be performed from the reflective surface side.

Conventionally, as a reflector support device that can adjust the vertical position of the reflector from the reflective surface side, for example, Utility Model Application No. 47-94473
There is a Utility Model Application No. 52-13975 that improves this.

First, the former Utility Model Application No. 47-94473 will be explained with reference to FIGS. 1A and 1S showing a plan view and a front view thereof. An upper adjustment mechanism consisting of a bolt 15, an adjustment nut 13, and a clamping nut 14, and a lower support fitting 1
6, a support bolt 15, and a lower adjustment mechanism consisting of a nut 17.The structure of the upper adjustment mechanism allows adjustment without lifting up of the reflector during adjustment, but a lid 18 for closing the hole after adjustment is provided. There is an inconvenience in that the adjustment mechanism requires adjustment, and furthermore, it is impossible to perform adjustment using the lower adjustment mechanism from the reflective surface side.

As an improvement on this drawback, Utility Application No. 52-1397
5 has been devised, and this invention will be described below with reference to FIGS.

This device includes a support fitting 22 that supports a reflector 21, an adjustment mechanism consisting of a support bolt 25, an adjustment nut 23, and a clamping nut 24, and a mechanism that is fixed to a reflector support structure 27 and integrally connects the support bolt 25. It has a base fixing part consisting of a fixed lower support metal fitting 26, and a large amount of adjustment can be obtained from the reflecting surface side, but the supporting position of the supporting metal fitting 22 is far from the reflecting surface position and there is a step, so it is necessary to This has disadvantages in that it is difficult to position the support position of the device, and in that a cover plate 28 is required to close the hole after adjustment.

The purpose of the present invention is to eliminate these drawbacks, to be able to accurately position the mounting position of the reflector before installing the reflector, and to achieve high accuracy because the reflector support position is close to the reflective surface. The object of the present invention is to provide a reflector support device that has numerous advantages such as easy adjustment and the ability to save parts because the clamping nut of the reflector support plate also serves as the lid of the above-mentioned example.

Describing the structure of the present invention, the reflector support device according to the present invention includes a lower support fitting fixed to a reflector support structure, and a riser that is screwed to the lower support fitting and positioned at the height of the reflector on the top surface. a support bolt having a reference mark for observation; an adjustment nut screwed onto the support bolt and having rotating pin holes arranged at equal circular intervals; a clamping nut having rotational through pin holes with the same diameter and the same alignment as the pin holes of the adjustment nut; and a clamping nut having a round hole in the center and clamped between the upper surface of the adjustment nut and the upper protruding shoulder of the clamping nut. The reflector support plate is tightened and has a plurality of reflector end portions fixed to the upper surface of the reflector support plate.

Hereinafter, the present invention will be explained by way of examples with reference to the drawings.

Figures 3a and 3a show a plan view and a partially sectional front view of an embodiment of the present invention, respectively.

In both figures, 31 is a reflecting plate, and 32 is shown in FIG. 4a.

As shown in the detailed diagram of the parts in Fig. 3b, it is a reflector support plate with a round hole in the center and through holes in the four corners, and as shown in Fig. The reflectors 31 are fixedly supported.

On the other hand, the reflector support structure 40 has a lower support fitting 4 having a cylindrical body with a thread groove cut on the inner upper part rising from the center part.
1 is fixed by bolting, and the central cylindrical body of the lower support fitting 41 has a support bolt 34 with a threaded groove around the periphery.
are screwed together, and the height of the support bolt 34 is adjusted by observing a reference mark for observing the height position of the reflector plate on the top surface thereof, and then is fixed with a fixing nut 42.

Next, on the upper part of the support bolt 34, there are marks shown in FIGS. 5a and 5b on the lower side.
The adjusting nut 35 is shown in detail in Figure 6, and the upper part is shown in Figure 6a.
A clamping nut 37, whose detailed diagram is shown in FIG. It looks like this.

The adjusting nut 35 and the clamping nut 37 are shown in FIG. 5, respectively.

As shown in Fig. 6, the rotating pin holes 3 are arranged at equal intervals in a circle
6 and 3B are provided with the same diameter and the same arrangement.

In the reflector support device having such a configuration, the procedure for adjusting the height position of the reflector 31 will be described. First, the reference mark 39 on the top surface of the support bolt 34 is placed at a predetermined height position by observation. After adjusting the height of the support bolt 34, the support bolt 34 is fixed to the lower support fitting 41 with a fixing nut 42.

Next, insert a wrench that is long enough to penetrate the adjusting nut 35 into the pin hole 38 of the clamping nut 37, and tighten the clamping nut 37 against the reflector support plate 32 until the tightening force is zero. Then, when the wrench is pushed down and the pin is placed on the top surface of the adjustment nut 35 and gently rotated, the pin will eventually fall into the pin hole 36 of the adjustment nut 35.

When the wrench is rotated in this state, the clamping nut 37 and the adjustment nut 35 rotate while maintaining a constant interval, and the surface of the reflector 31 fixed to the reflector support plate 32 is fixed to the support bolt 3.
The height position is made to match the height position of the reference mark 39 on the top surface of 4.

By rotating and tightening only the clamping nut 37 with a wrench at that position, the reflecting plate 31 can be fixed at that position.

As described above, according to the present invention, since the reflector support device itself has a reference point such as the above-mentioned reference mark, it is possible to accurately adjust the reflector mounting position using only the reflector support device. The reflector can be supported and adjusted close to the reflector surface, allowing for highly accurate adjustment.Furthermore, it not only requires fewer parts, but also improves work efficiency. is obtained.
