Abstract

The present invention relates to a clamping apparatus for an antenna. Particularly, the clamping apparatus comprises: an arm unit which is coupled to a support pole and has a mounting space formed in a tip portion thereof and open in a longitudinal direction; a rotation unit which is detachably mounted in the mounting space of the arm unit and has a tip portion coupled to be rotatable predetermined angle in the left and right directions with respect to a hinge point in the mounting space; a tilting unit which is coupled to the tip portion of the rotation unit so as to be tiltable in the up and down directions and mediates the coupling of an antenna device; and a mounting guide unit which is provided in the rotation unit, and is elastically pressed and then temporarily fixed to the hinge point of the mounting space when the rotation unit is mounted in the mounting space of the arm unit. Thus, the present invention provides the advantages of removing spatial limitations for a plurality of antenna devices with respect to the support pole, and improving workability.

First claim

The invention claimed is:

1. A clamping apparatus for an antenna comprising:
an arm unit that coupled to a support pole and has a mounting space formed in a tip portion thereof so as to open in a longitudinal direction;
a rotation unit that is detachably mounted in the mounting space of the arm unit and has a tip portion coupled to be rotatable about a hinge point in the mounting space at a predetermined angle in a left-right direction;
a tilting unit which is coupled to the tip portion of the rotation unit so as to be tiltable in an up-down direction and configured to mediate coupling of an antenna device; and
a mounting guide unit that is provided to the rotation unit, and is elastically pressed, and then is temporarily fixed to the hinge point in the mounting space when the rotation unit is mounted in the mounting space of the arm unit.

2. The clamping apparatus for an antenna according to claim 1 , wherein the mounting guide unit comprises:
a guide tube that is provided such that an outer end thereof is protrudable outward from a lower hinge fastening hole, which is provided such that a part of the rotation unit which corresponds to the hinge point in the mounting space is recessed, at a predetermined length; and
an elastic body that elastically supports the guide tube in an outward direction of the rotation unit.

3. The clamping apparatus for an antenna according to claim 2 , wherein an outer end of the guide tube protrudes at a length at which the guide tube is inserted into and caught in a hinge hole formed at the hinge point in the mounting space of the arm unit.

4. The clamping apparatus for an antenna according to claim 2 , wherein a lower rotating pin passes through the hinge point at an outer side of the arm unit and is inserted into and installed in the guide tube.

5. The clamping apparatus for an antenna according to claim 2 , wherein the mounting guide unit further comprises an anti-separation nut that is screwed to an inner circumferential surface of the lower hinge fastening hole so as to prevent outward separation of the guide tube.

6. The clamping apparatus for an antenna according to claim 5 , wherein:
the anti-separation nut is located between an outer circumferential surface of the guide tube and the inner circumferential surface of the lower hinge fastening hole; and
a hanging rib hung on the anti-separation nut is formed radially outward on the outer circumferential surface of the guide tube so as to extend in a circumferential direction.

7. The clamping apparatus for an antenna according to claim 1 , wherein the arm unit comprises:
an outer mounting block that is disposed to come into close contact with one side of an outer circumferential surface of the support pole;
an inner mounting block that is disposed to come into close contact with the other side of the outer circumferential surface of the support pole and is fixed with the outer mounting block by at least one or more fixing bolts; and
a clamp arm that extends from the inner mounting block at a predetermined length in a direction orthogonal to the support pole and constitutes a tip portion to which the mounting space is provided.

8. The clamping apparatus for an antenna according to claim 7 , wherein at least one or more reinforcement ribs are formed at a connection part between the inner mounting block and the clamp arm.

9. The clamping apparatus for an antenna according to claim 7 , wherein the clamp arm is manufactured at multiple preset lengths so as to be installable in a different separation distance from the support pole depending on another antenna device, which is installed adjacent to the antenna device coupled to the tilting unit, and surrounding interference bodies.

10. The clamping apparatus for an antenna according to claim 7 , further comprises a reinforcement wire unit having a connecting wire, one end of which is fixed to a part of the support pole which corresponds to an upper portion of the arm unit, and the other end of which is fixed to the clamp arm of the arm unit.

11. The clamping apparatus for an antenna according to claim 10 , wherein the reinforcement wire unit is selectively installed in consideration of fatigue strength of a connection part between the inner mounting block and the clamp arm depending on weight of the antenna device coupled to the tilting unit and a length of the clamp arm.

12. The clamping apparatus for an antenna according to claim 7 , wherein at least one rotation guide part is formed at a tip portion of the clamp arm, to which the mounting space is provided, in a slot hole shape so as to guide a rotating motion of the rotation unit.

13. The clamping apparatus for an antenna according to claim 12 , wherein the rotation guide part comprises:
at least one rotation guide slot that is formed in a circumference having a common center with the hinge point; and
a rotation guide bolt that passes through the at least one rotation guide slot from an outside and is fixed to the rotation unit.

14. The clamping apparatus for an antenna according to claim 13 , wherein a rotating angle label, which indicates a position of the rotation guide bolt moved in the rotation guide slot from a reference point at an angle, is attached to the tip portion of the clamp arm.

15. The clamping apparatus for an antenna according to claim 1 , wherein the rotation unit comprises:
tilting unit installing stages to which the tilting unit is tiltably coupled;
a rotating block that is inserted into the mounting space of the arm unit; and
a connecting block that interconnects the tilting unit installing stages and the rotating block.

16. The clamping apparatus for an antenna according to claim 15 , wherein:
A rotating braking washer pad is interposed between the rotating block and the arm unit; and
tilting braking washer pads are interposed between the tilting unit installing stages and the tilting unit.

17. The clamping apparatus for an antenna according to claim 16 , wherein:
