Abstract

PURPOSE: An antenna clamp is provided to allow installation of antenna to be easily performed and reduce installation time, while allowing the antenna direction to be readily adjusted when needed. CONSTITUTION: An antenna clamp comprises the first clamp(22) inserted and assembled to a bracket(21), and which has rotation shafts(25) arranged at upper and lower surfaces of the first clamp; and the second clamp(23) assembled to the first clamp, and which has stoppers(27) formed at upper and lower surface of the second clamp and fixing holes(28) formed at the left and right sides of the second clamp. The antenna clamp is assembled to an antenna in such a manner as to be aimed both in horizontal and vertical directions. The first clamp is movable in a vertical direction along a slot(26) by utilizing a rotation shaft(24), and fixed by a screw. The second clamp is movable in a horizontal direction by utilizing the rotation shaft(25), and fixed by a screw. The maximum degree of the second clamp is restricted by the stopper formed at the second clamp.

Description

Antenna clamp device capable of tilting up, down, left and right

The present invention relates to an antenna clamping device, and more particularly, to an antenna clamping that is easy to install and that can be adjusted in up, down, left, and right directions so as to be able to tilt in the vertical direction and adjust in the left and right directions. Relates to a device. In order to install antennas used in various mobile communication systems such as personal cellular communication or cellular, outdoor poles are built with a plurality of poles at each base station, and antennas are mounted at the upper end thereof, and in the case of indoors, antennas are fixed to walls. At this time, the antennas are installed by using a clamping device.

The antenna clamping device as described above is a device for fixing an antenna to a wall or a structure, and in order to install the antenna, it is not only dangerous because it is necessary to work for a long time using both hands while standing on a high antenna structure. In order to reinstall the installed antenna in any of up, down, left and right directions, there was a problem in that the same operation as the initial installation was repeated.

The present invention has been made to solve the problems of the prior art as described above is easy to install, easy to adjust the case when the direction angle of the antenna is changed to the wind or external impact or if the angle must be changed up or down or left and right as needed. Therefore, the technical problem is to provide an antenna clamping device that can be adjusted in the up, down, left and right directions to reduce the risk of the installer by reducing the working time.

Antenna clamping device that can be adjusted in the up, down, left and right directions according to the present invention Brackets bent in the shape of a chair having a first rotating shaft and a groove, respectively; A first clamp inserted into the bracket and assembled to the bracket, the first clamp having a second rotating shaft disposed on an upper and lower surface thereof; The second clamp is assembled to the first clamp but has a locking jaw and a fixing hole on the upper and lower surfaces, respectively.

Hereinafter, the characteristics and operation principle of each part of the antenna clamping device according to the present invention will be described in detail according to the accompanying drawings. 1 is a plan view showing an antenna clamping device according to the prior art. The first clamp 12 and the second clamp 13 are coupled to each other to have a rectangular shape, one side of which is mounted with an antenna 11 and the other side thereof with an antenna pole 15 coupled thereto. The clamp cover 14 and the first clamp 12 are coupled by a polygonal bolt 18 with the antenna pole interposed therebetween, first using the bolt head 16 and the nut 17 to remove the polygonal bolt. 1 is fixed to the clamp 12, the clamp cover 14 is covered and then the nut 17 to tighten the first clamp 12, the antenna pole 15 and the bolt 13 in order to join. At this time, in order to couple the bolt 13, the bolt head 16 must be fixed with one hand and the nut 17 must be tightened with the other hand. Therefore, there was a problem that the assembly was not easy and the precision was also poor.

Figure 2a is an external perspective view of the antenna clamping device that can be adjusted in the up, down, left and right directions according to the present invention. Bracket 21 The first rotating shaft 24 and the groove 26 are each bent in the shape of a child, and the first rotating shaft 24 and the groove 26 are fitted, and the first clamp 22 having the second rotating shaft 25 is assembled on the upper and lower surfaces thereof. The second clamp 23 is assembled to the first clamp but the locking jaw 27 and the left and right fixing holes 28 are connected to the upper and lower surfaces, respectively. In this operation of FIG. 2A, the first clamp 22 is movable up and down along the groove 26 with respect to the first rotating shaft 24, and is fixed by a screw after the movement, and is provided in the first clamp. The second clamp 23 can be moved left and right about the second rotating shaft 25, which is fixed by a screw as described above, and rotates by a locking jaw 27 provided in the second clamp. The maximum possible angle is limited. In addition, the fixing holes 28 provided on the left and right sides of the second clamp are fixed to or fastened with a screw on a wall or the like, and the antenna is assembled to the bracket. FIG. 2B is a perspective view of FIG. 2A, and FIG. 3 is a mounting view showing an embodiment of an antenna clamping device which can be adjusted in up, down, left and right directions according to the present invention.

Therefore, the antenna clamping device which can be adjusted in the up, down, left, and right directions according to the present invention has an effect that the installation work is easy and the installation time is shortened, thereby reducing the risks encountered during installation. It also has the effect that it can be easily realized when the direction of is changed or the direction of the antenna needs to be changed as necessary.
