Description

Antenna holder and supporting device using same

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an antenna supporting apparatus, and more particularly, to an antenna holder and a supporting apparatus which are designed to be fixed by arbitrarily adjusting the direction and angle of an antenna.

A so-called sector antenna having directionality and directivity, which is installed in a mobile communication base station, has components and their arrangement for maximizing the propagation distance or beam titration, and is a means for installing a directional antenna There is a need for a supporting device capable of appropriately adjusting the tilt angle of the antenna.

A number of devices having this object have been proposed, basically including upper and lower brackets, the technical features of which are primarily related to the upper bracket.

The bracket structure in this field generally includes:

First, a structure having a "V" -shaped link member whose both joints are angled as they expand and contract about an intermediate axis, such as in an antenna fixture disclosed in U.S. Utility Model Publication No. 2010-12684;

A structure having a linear link member that is angularly adjusted as one arm is rotatably connected to both shafts, as in the antenna angle adjusting device disclosed in Japanese Laid-Open Patent Publication No. 2003-69260;

.

1 shows the latter example,

Brackets 102 and 103 are provided on the upper and lower sides of the support base 101, and the antenna A:

The lower portion is only attached to the lower bracket 103 using the shaft 104;

The upper portion is connected to the upper bracket 102 via an arm 105 extending between the upper bracket 102 and the antenna A and having both ends joined by shafts 106 and 107;

Respectively.

Here, a fixing piece 108 through which the shafts 104 and 106 can penetrate is attached to the lower portion and the upper portion of the antenna A, respectively.

Specifically, the antenna A is configured such that the end of the arm 105 is vertically moved upward and downward along the elongated hole 109 of the upper bracket 102 so that the installation angle? The center of gravity of the shaft 104 is gradually increased. With this method, it becomes possible to adjust the angle with respect to the inclination of the installed antenna A. [

It is true that such an angle adjustment is quite effective for a sector antenna. However, in this bracket or supporting structure, the installed antenna itself can not be rotated, and therefore the direction of the antenna can not be changed. In fact, in a high gain polarized antenna, the polarization (rotation) variable can be an important factor for determining the efficiency or the characteristic as well as the tilt (gradient) variation above.

However, in the above example, there is no mention of polarization variation, and there is a problem that is impossible at all in terms of structure.

The present invention has been proposed to solve the problems of the above-mentioned prior arts. It is an object of the present invention to provide an antenna holder capable of changing the direction of an antenna. Another object of the present invention is to provide an antenna supporting apparatus capable of both polarization variation and tilt change of an antenna by using the holder.

The antenna holder of the present invention comprises:

An outer ring-shaped or arc-shaped frame for providing a rotating frame;

An antenna grasping unit for grasping and holding the antenna body, the antenna grasping unit being rotatably provided inside the frame;

A fixing member for fixing the grip portion in the frame;

.

The grip portion is provided inside the frame in such a manner that at least left and right outer surfaces contact the inner wall of the frame. At this time, the left or right side includes the cutout portion, thereby enabling expansion and contraction of the inside space of the gripping portion.

The fixing member includes an engaging portion formed to protrude outward from the grip portion and to be pressed onto the edge of the frame. Preferably, the fastening member further comprises a plurality of recesses formed such that the fastening portions are correspondingly seated along corners of the frame.

Preferably, the gripping portion comprises:

A first grip portion and a second grip portion disposed on both sides of the frame;

Fastening means for bringing the first gripping portion and the second gripping portion in confrontation with each other;

The fastening member may include: a fastening part which is pressed onto the edge of the frame when tightly and fixes the fastening part to the frame;

.

The antenna support apparatus of the present invention comprises:

Upper and lower brackets spaced apart from each other on the upper and lower sides of the building;

The holder being configured to grip and hold the antenna body;

A support having an arm extending between the upper bracket and the holder and having both ends connected to the rotation axis;

An antenna receiving part connected to the lower bracket via a rotation shaft;

.

Preferably, the upper bracket includes a fixing base having a vertical slot, and the one-end rotation axis of the arm is configured to slide along the slot. Meanwhile, the receiving portion includes a plurality of fixing holes formed on the same radius around the shaft hole.

The antenna holder of the present invention comprises a frame for providing a rotating frame and an antenna holding portion rotatably provided inside the frame. Therefore, even if the frame is fixed to the outside, the direction of the antenna can be adjusted. In addition, the antenna supporting device of the present invention can adjust the inclination angle of the antenna by using an arm whose both ends are connected to each other via a rotation shaft. Therefore, according to the embodiment of the present invention, both of the polarization change due to the rotation of the antenna and the tilt change due to the tilt adjustment can be achieved easily.

The features and effects of the present invention 'antenna holder and supporting device using the same' described or not described above will become more apparent from the following description of the embodiments with reference to the accompanying drawings. 2, the antenna holder according to the present invention is denoted by reference numeral 10, and the antenna supporting apparatus is denoted by reference numeral 30. In Fig.

2 to 4, an antenna holder 10 according to the present invention includes a frame 11 for providing a rotating frame, an antenna gripper 12 rotatably provided on the frame 11, And a fixing member 13 for fixing the grip portion 12 in the frame 11. [

The frame 11 is preferably ring-shaped, and in this embodiment, the gripper 12 can rotate 360 ° inside the frame 11. [ However, in another embodiment in which the rotation range of the grip portion 12 is not necessarily wide, the frame 11 may be formed in an arc shape corresponding to a limited rotation range. Reference numeral 14 denotes a flat bar integrally formed on one side of the ring portion of the frame 11. [

The grip portion 12 is rotatably provided inside the frame 11 in the form of surrounding the antenna A body. The grip portion 12 is provided inside the frame 11 in such a manner that at least left and right outer surfaces thereof contact the inner wall of the frame in a round (R) manner. At this time, the left or right side includes the cutout portion 15, thereby enabling expansion and contraction of the inner space of the grip portion 12. [

Specifically, the grip portion 12 includes a first grip portion 16 and a second grip portion 17 disposed on both sides of the frame 11, and two grip portions 16 and 17 disposed opposite to each other And a fastening member (18) which is in close contact with each other. Preferably, each gripping portion 16, 17, which is of the same shape,

The left and right side surfaces are in close contact with the inner surface of the frame 11 in a round R;

The inner space can be expanded and contracted by using the one cut-out portion 15;

So as to enclose, press and grasp the antenna (A) within the frame (11);

Consists of.

The fastening means 18 includes a shaft 19 extending between the shaft holes of the both grip portions 16 and 17 and a shaft 19 extending in the axial direction of the shaft 20, And a rotary pressing lever 20 of FIG. When the lever 18 of this type is used, there is an advantage that both the gripping portions 16 and 17 can be easily contacted and released.

Preferably, the fastening means 18 is formed selectively or simultaneously on the upper and lower surfaces of the grip portions 16 and 17, which are not in close contact with the inner surface of the frame 11. This has the advantage that the empty space between the grip portion 12 and the frame 11 can be utilized.

The fixing member 13 includes an engaging portion 22 protruded outward from the grip portion 12 and pressed against the edge 21 of the frame 11. The fixing member 13 preferably further includes a plurality of recesses 23 formed in correspondence with the engaging portions 22 along the edge 21 of the frame 11. In the present embodiment, when the two grip portions 16 and 17 are in close contact with each other, the engaging portion 16 is engaged with the corner groove 23 of the frame 11 and pressed to prevent the grip portion 12 from flowing.

According to the above structure of the holder 10, rotation and polarization adjustment of the antenna A are possible.

3, when the lever 20 of the fastening means 18 is rotated, the close contact between the fixing member 13 and the frame 11 is released. In this state, the grasping portion 12 can be rotated as much as necessary, and at the same time, the rotation of the antenna A held by the grasping portion 12 and the polarization control can be adjusted accordingly. After the polarization adjustment is completed, the lever 20 is rotated in the opposite direction again to return to the original position. The engaging portion 22 is pressed against the edge 21 or the groove 23 of the frame 11 and the grip portion 12 and the antenna A are fixed while being adjusted.

5 and 6, an antenna supporting device 30 according to the present invention includes upper and lower brackets 31 and 32 spaced apart from each other on upper and lower sides of a structure, And a support including at least one arm 33 extending between the upper bracket 31 and the holder 10 and having opposite ends connected to the rotation axis 34 and 35. The antenna bracket (36) is connected to the lower bracket (32) by a rotation shaft (37).

In this embodiment, the arm 33 is a straight arm. However, depending on the design, it may be composed of a plurality of arms that are expanded or contracted to 'V' type or 'W' type or the like. In this embodiment, the upper bracket 31 includes a fixing base 38 having a vertical slot 39, and one end rotation shaft 35 of the arm 33 is slid along the slot 39 .

As shown in the figure, the shaft 34 connecting the arm 33 and the holder 10 is provided with a rotary pressing lever 40 similar to the case of the fastening means 18, So that the facing portions of the two structures 33 and 10 are brought into close contact with each other. On the other hand, the radial tooth structures 41 corresponding to each other are formed on the facing portions.

Meanwhile, the support portion 36 includes a plurality of bolt-compatible fixing holes 42 formed on the same radius around the shaft hole 43. This configuration is effective for varying the polarization of the antenna A and fixing it. Here, the shaft hole 43 is used as a hole into which the antenna A connector is inserted.

7, when the shaft 35 on the side of the bracket 31 is downward along the slot 39 while the shaft 34 on the holder 10 side of the arm 33 is disengaged, The holder 10 holding the antenna A from the upper side is pushed out of the structure C while moving from the vertical to the almost horizontal state. At this time, since the antenna receiving portion 36 only rotates the shaft 37 at the lower bracket 32, the antenna A has a slope of a certain angle?.

In this way, the tilt adjustment and the tilt change of the antenna A are possible. When the adjustment is completed, the lever (40) connected to the shaft (34) on the holder (10) side of the arm (33) is rotated to return to the tightened state. By this tightening and thus the engagement of the tooth structure 41, the adjustment state can be maintained as it is.

Referring to FIG. 8, the polarization of the antenna A can be varied by the rotation of the holder 10, as described above. At this time, the position of the corresponding fixing hole 42 changes in the receiving portion 36 supporting the lower portion of the antenna A. Therefore, the position of the bolt and the corresponding hole 42 for fixing the antenna A before and after the adjustment may be appropriately selected from a plurality of holes 42 located at the same radius.
