The tension spring 141 has one end fixed to the first shaft 134 and the other end fixed to the other end of the rod 135. When the rod 135 is pulled out from the cylinder 131, the tension spring 141 generates a tensile force that pulls the rod 135 to adjust the speed at which the rod 135 is pulled out.

Adjusting the speed at which the rod 135 is pulled out prevents the mounting frame 110 from being suddenly bent due to the weight of the antenna 10, and allows the angle of the mounting frame 110 to be gradually adjusted, thereby causing injury to the operator. This is to prevent accidents such as back.

The tension spring 141 has a tensile force proportional to the weight of the antenna 10. In the case of a 5G antenna, the weight is considerable from 25kg to 45kg. Therefore, if one side of the angle adjustment unit 130 is configured to be stretchable by applying a tension spring 141 having a tensile force proportional to the weight of the antenna 10, it is easy to adjust the angle of the antenna, and the antenna is more than the set angle. The safety of the operator can also be secured by preventing it from being suddenly tilted.

In the embodiment, the number and spacing of the second angle adjusting holes 137 and the number and spacing of the second angle adjusting holes 137 are manufactured based on a maximum of 45°, but can be variously changed according to a desired angle. However, if too many holes are drilled in the cylinder 131 and the rod 135, the strength of the angle adjusting unit 130 is weakened, so it can be variously changed within a range that does not affect the strength of the angle adjusting unit 130. .

The fixing members 143 and 144 are fastened through the first angle adjusting hole 133 and the second angle adjusting hole 137 communicated with each other to fix the adjusted angle. The first angle adjustment hole 133 and the second angle adjustment hole 137 are formed in a manner of symmetrically drilling holes on both sides of the cylinder 131 and the rod 135 so that the fixing members 143 and 144 can pass through.

On the rod 135, a scale for checking the angle at which the mounting frame 110 is adjusted is displayed. The operator can adjust the angle of the mounting frame 110 by checking the scale marked on the rod 135 while withdrawing the rod 135 from the cylinder 131. In this way, the scale formed on the rod 135 allows the operator to visually check the angle of the mounting frame 110 and facilitate the angle adjustment operation.

In addition, after adjusting the angle of the mounting frame 110, it is possible to easily check the setting angle of the mounting frame 110 in the angle display unit 145 located below.

When the angle of the mounting frame 110 is adjusted, the mounting frame 110 includes a bump (refer to reference numeral 148 of FIG. 5) for preventing the mounting frame 110 from being bent beyond the set range. The bump 148 restricts the mounting frame 110 from bending beyond a predetermined angle.

The elastic portion 151 is formed with an incision slit 152 so that the fixing pole 210 is inserted by elastic deformation. The incision slit 152 allows the fixing pole 210 to be easily inserted into the support pole 150.

The fixing part 155 is a part extending from the elastic part 151 in the direction in which the fixing pole 210 is inserted. The fixing part 155 is a part that is press-fitted while the fixing pole 210 inserted into the elastic part 151 is further inserted. The fixing part 155 is an upper portion of the elastic part 151 in which the incision slit 152 is not formed in the support pole 150.

The fastening part 153 is formed to protrude from both ends of the elastic part 151 based on the incision slit 152 and has fastening holes. The tightening bolts 154 are fastened to the fastening holes of the two fastening parts 153 protruding from both ends of the elastic part 151 to fasten and fix the part of the fixing pole 210 positioned on the elastic part 151.

The support pole 150 further includes a pressure bolt 156 fastened through a fixing hole formed in the fixing part 155. The pressure bolt 156 serves to more firmly fix the fixing pole 210 coupled to the support pole 150 by pressing the outer surface of the fixing pole 210 positioned to correspond to the fixing hole.

When only the coupling portion of the fixing pole 210 and the support pole 150 located on the elastic part 151 is fixed, the bonding strength between the support pole 150 and the fixing pole 210 may be weak. Therefore, by fastening the pressing bolts 156 to the fixing part 155 without elastic force, the fixing pole 210 is doublely fixed to the support pole 150. This prevents the state in which the fixed pole 210 is coupled to the support pole 150 from being separated or twisted by an external force.

As shown in FIG. 11, the weight of the antenna 10 can be securely fixed to the mounting frame 110 using the branch line 170.

The method includes fixing one end of the branch line 170 to the fixing ring 11 provided at the top end of the antenna 10, and having the other end of the branch line 170 on the top surface of the mounting frame 110 ( 161 and the second guide ring 162 provided at the rear center of the mounting frame 110 may be sequentially passed and then pulled.

When the antenna 10 is raised to a position fixed to the mounting frame 110, the other end of the branch line 170 is tied and fixed to the second guide ring 162 or the third guide ring 163, and then the antenna 10 is mounted. When fixed to the frame 110, it is possible to prevent safety accidents such as the antenna 10 from falling.

The antenna 10 raised to a position that can be fixed to the mounting frame 110 is a locking bracket 112 fixed by hanging on the mounting frame 110 and a fixing bracket 115 fixed by bolting to the mounting frame 110 ) Can be fixed by additional bolts.

For the convenience of installation, in a state where the locking bracket 112 and the fixing bracket 115 are bolted to the rear surface of the antenna 10 in advance and fixed, the antenna 10 is positioned to be fixed to the mounting frame 110. When positioned, first fix the antenna 10 to the mounting frame 110 by hooking the locking bracket 112 to the locking protrusion of the mounting frame 110, and then fasten the fixing bracket 115 to the mounting frame 110 by bolts Can be fixed.

As shown in FIGS. 12 and 13, the antenna 10 may be configured by combining several antennas. In the case of configuring a combination of several antennas 10, several foundation frames 200 are installed by connecting the fixed poles 210 with a connecting rod 300, and each fixed pole 210 of the foundation frame 200 is The support pole 150 of the antenna angle adjustment device 100 may be combined.

The angle of the range covered by one antenna is about 120 degrees. Therefore, in 5G, one base station can be configured with three antennas to cover 360 degrees in front. For example, three antennas are installed on the roof of a building, and each antenna can cover 360 degrees by adjusting the angle, and 5G service can be stably provided by expanding the radio wave transmission range.

Meanwhile, in FIGS. 14 and 15, an antenna angle adjustment apparatus according to another embodiment of the present invention is shown.

14 and 15, the antenna angle adjustment apparatus 100 according to another embodiment of the present invention has a configuration of the angle adjustment unit 130a different from the embodiment, so that the difference between the angle adjustment unit 130a Only the configuration will be described in detail.

The angle adjusting part 130a of another embodiment more precisely supports the speed at which the mounting frame 110 is tilted forward due to the weight of the antenna by inserting the configuration of the rod and the tension spring of the embodiment into the interior of the mounting frame 110 To be able to do it.

The angle adjustment unit 130a includes a rotating frame 131a, a moving frame 135a, a tension spring 141a, and a fixing means.

One end of the rotating frame 131a is coupled to the support frame 120 by a first shaft 134. One end of the rotating frame 131a is rotatably coupled to the first shaft 134 installed in the support frame while being inserted into the first guide long hole 119 of the support frame 120. The other end of the rotating frame 131a is rotatably coupled to the moving frame 135a.

The moving frame 135a is disposed to be movable in the vertical direction inside the mounting frame 110 corresponding to the second guide long hole 123. The other end of the rotating frame 131a is rotatably coupled to one end of the moving frame 135a by a rotating shaft 139a. The other end of the moving frame 135a is supported by a tension spring 141a disposed inside the mounting frame 110.

One end of the tension spring 141a is fixed to the other end of the moving frame 135a, and the opposite end is fixed to the fixed shaft 110a of the mounting frame 110. The tension spring (141a) is a moving frame in a direction opposite to the direction in which the rotating frame (131a) pulls the moving frame (135a) when the rotating frame (131a) is rotated due to the weight of the antenna fixed to the front of the mounting frame (110) By generating a tensile force that pulls 135a, the speed at which the rotating frame 131a is rotated is adjusted.

That is, the tension spring (141a) is the moving frame (135a) in the upper direction opposite to the force that the rotation frame (131a) pulls the moving frame (135a) downward by the force of the mounting frame 110 to rotate forward. ) By exerting a pulling force, and by adjusting the rotation speed of the rotation frame 131a, the speed at which the mounting frame 110 rotates forward is controlled.

The fixing means fixes a state in which the moving frame 135a is moved within the mounting frame 110. The fixing means includes a first angle adjustment hole 114a, a second angle adjustment hole 137a and a fixing member 143a. The first angle adjustment hole 114a is a plurality of holes formed at predetermined intervals in the mounting frame 110. The second angle adjusting hole (137a) is two or more holes formed in the moving frame (135a) to selectively communicate with the first angle adjusting hole (114a). The fixing member (143a) is fastened through the first angle adjustment hole (114a) and the second angle adjustment hole (137a) in a state in which the first angle adjustment hole (114a) and the second angle adjustment hole (137a) are in communication. . On the outer surface of the mounting frame 110 corresponding to the first angle adjustment hole 114a, a scale for confirming the adjusted angle is written.

In the case of another embodiment, since the moving frame 135a and the tension spring 141a are disposed inside the mounting frame 110, the tension spring 141a is supported by the mounting frame 110 while being supported by the rotation frame 131a. By exerting an internal tensile force for the mounting frame 110 is adjusted to rotate the speed.

And, in the case of the embodiment, since the rod and the tension spring are connected to the cylinder, the tension spring 141a directly exerts an internal tension force with respect to the rotation of the mounting frame 110 to adjust the speed at which the mounting frame rotates. Therefore, in the case of another embodiment, the speed at which the mounting frame rotates can be more precisely controlled and supported than in the case of the embodiment.

Although not shown, the angle adjustment unit 130a adjusts the angle of the mounting frame by connecting the support frame 120 and the mounting frame 110 with the rotating frame 131a, but at one end of the rotating frame, the tension spring structure of the embodiment is The other end that is opposite to the applied may be configured to allow angle adjustment at both one end and the other end of the rotating frame by applying the tension spring structure of another embodiment.

The angle adjustment unit 130 of the present invention configures the axis for adjusting the angle in a buried type and adjusts the angle of the antenna by the internal tension force by the tension spring, so that the angle adjustment can be performed in a simple and simple design, as well as the angle adjustment. It is also easy.

Compared to the case of adopting a method of adjusting the angle by rotating both sides by using a turnbuckle to increase the length, the above-described angle adjusting unit 130 has a simple structure, low manufacturing cost, and a simple manufacturing process.
