Description

Technical Field

[0001] This invention relates to an antenna clamping device, and more specifically, to an antenna clamping device that allows for efficient configuration of antenna equipment in densely packed spaces and easy adjustment of the orientation of the antenna equipment. Background Technology

[0002] Wireless communication technologies, such as Multiple Input Multiple Output (MIMO), are techniques that greatly increase data transmission capacity by using multiple antennas. In MIMO, the transmitter transmits different data through each transmitting antenna, and the receiver distinguishes the transmitted data through appropriate signal processing using spatial multiplexing methods.

[0003] Therefore, as the number of transmitting or receiving antennas increases simultaneously, channel capacity increases, enabling the transmission of more data. For example, increasing the number of antennas to 10 ensures approximately 10 times the channel capacity compared to an existing single-antenna system using the same frequency band.

[0004] In 4G LTE-advanced, up to eight antennas were used. Currently, in the pre-5G stage, products with 64 or 128 antennas are being developed. It is expected that 5G will use base station equipment with an even greater number of antennas, which is called Massive MIMO technology. Current cell operation is two-dimensional; by introducing Massive MIMO technology, three-dimensional beamforming can be achieved, hence it is also called Full Dimension MIMO (FD-MIMO).

[0005] In massive MIMO (Multiple-Input Multiple-Output) technology, the number of antennas (ANTs) increases, along with the number of transmitters and filters. Even so, due to rental availability or space constraints at installation sites, it is necessary to manufacture radio frequency (RF) components (antennas, filters, power amplifiers, transceivers, etc.) small and lightweight to reduce costs. The high output required for coverage expansion in massive MIMO technology leads to increased power consumption and heat generation, which negatively impacts weight and size reduction.

[0006] In particular, when a multi-input multi-output antenna is set up in a stacked structure to combine modules of radio frequency devices and digital devices within a limited space, the need for compact and miniaturized design related to the multiple layers constituting the multi-input multi-output antenna becomes prominent in order to maximize ease of setup or space utilization. There is also a strong need for free directional adjustment of the antenna device mounted on a support pole. Summary of the Invention

[0007] Technical issues

It should be noted that, in assigning reference numerals to structural elements in the various drawings, the same reference numerals are used as much as possible for the same structural elements, even if they appear in different drawings. Furthermore, in the process of describing the present invention, if it is determined that a detailed description of a related known structure or function may hinder the understanding of the embodiments of the present invention, such detailed description will be omitted.

These terms are used only to distinguish one structural element from others, and the nature, order, or sequence of the structural elements are not limited by their terminology.

[0049] Figure 1 This is a perspective view showing an example of the installation state of an antenna device according to an embodiment of the antenna clamping device of the present invention. Figure 2 A perspective view showing an embodiment of the antenna clamping device of the present invention is provided. Figure 3 for Figure 2 The settings of the exploded 3D diagram, Figure 4 To show Figure 2 An exploded perspective view of the tilting and rotating elements in the structure. Figure 5 This is a part of a horizontal cross-sectional view of the antenna clamping device of the present invention. Figure 6 This is a portion of a vertical cross-sectional view of the antenna clamping device of the present invention.

[0050] like Figures 1 to 6As shown, one embodiment of the antenna clamping device 50 of the present invention includes: an arm unit 300, which is combined with a support rod 1; a rotation unit 200, which is combined with the arm unit 300 in a manner that allows it to rotate in the left-right direction; and a tilting unit 100, which is combined with the rotation unit 200, which acts as a medium for the combination of the antenna device A, and is combined with the rotation unit 200 in a manner that allows it to tilt in the up-down direction.

[0051] The arm unit 300 acts as a medium for the connection with the mast 1 of the antenna device A. The antenna device A connected by the antenna clamping device 50 according to an embodiment of the present invention can be an antenna device A that is applicable to the massive MIMO technology described in the "Background Art" or the full-dimensional MIMO technology capable of 3D-beamforming.

[0052] In essence, the arm unit 300 described above can be formed in the following manner: it is bolted to one side and the other side of the outer peripheral surface of the mast 1 and extends a predetermined length in a direction orthogonal to the length direction of the mast 1, so that the antenna device A is separated from the mast 1 by a predetermined length.

[0053] like Figure 1 As shown, the support pole 1 may also include: a plurality of support poles 3 extending downward at an angle from the outer periphery of the support pole 1, extending radially at predetermined angles; and a support plate 5 disposed at the front end of the plurality of support poles 3, and combined with ground or wall support.

[0054] Multiple support rods 3 can be fixed to the pole 1 by welding to form a whole, and can also be manufactured separately to be combined with the pole 1 by bolting or other methods.

[0055] Furthermore, the support plate 5 may have bolt fastening holes (not shown) to allow it to be fastened to the ground or wall using bolts or other fastening components. In one embodiment of the invention, the support plate 5 is in the form of a panel, but it can also be designed, according to embodiments, to be in the form of a block with a specified weight, acting as a weight axis at three points in the installation location and providing stable support.

[0056] On the other hand, the rotating unit 200 is combined with the front end of the arm unit 300 in a manner that allows it to rotate in the left-right direction. The rotating unit 200 rotates in the left-right direction with the front end of the arm unit 300 as a reference, which essentially serves to facilitate the design of the left-right directivity of the antenna device A combined with the tilting unit 100.

[0057] Furthermore, the tilting unit 100 is combined with the front end of the rotating unit 200 in a manner that allows it to tilt and rotate in the vertical direction. The tilting unit 100 tilts and rotates in the vertical direction with the front end of the rotating unit 200 as a reference, which essentially serves to facilitate the design of the vertical directivity of the antenna device A to which it is combined.

[0058] As described above, in one embodiment of the antenna clamping device 50 of the present invention, the frequency radiation direction released from the front of the antenna device A combined with the mast 1 is rotated in the left-right direction and the angle is fixed by the rotation unit 200, and the angle is fixed by the tilting unit 100 tilting in the up-down direction. The angle-fixed state by the rotation unit 200 and the tilting unit 100 will be described in more detail below.

[0059] For ease of understanding, the direction in front of antenna device A is defined as "front", the opposite direction is defined as "rear", the left side of the front is defined as "left direction", the right side of the front is defined as "right direction", the top side of antenna device A is defined as "top direction", and the bottom side of antenna device A is defined as "bottom direction".

[0060] The following description will focus on antenna device A and begin with the adjacent structures for a more detailed explanation.

[0061] like Figures 1 to 4 As shown, antenna device A is combined with the front end of tilting unit 100. More specifically, with antenna device A combined with the front end of tilting unit 100, tilting unit 100 is combined with the front end of rotating unit 200 in a tiltable and rotatable manner. In this state, as... Figure 3 As shown, the rotating shaft 230 of the rotating unit 200 is inserted into the rotating shaft groove 331 formed at the front end of the arm unit 300, and the arm unit 300 is fixed to the support rod 1, as shown. Figure 2 As shown, the antenna device A can be set up using one embodiment of the antenna clamping device 50 of the present invention.

[0062] Among them, such as Figure 3 and Figure 4 As shown, the tilting unit 100 may include: an antenna coupling end 101, which is coupled to the antenna device A; and a tilting coupling end 103, which is coupled to one outer side or the other outer side of the rotating unit 200.

[0063] The tilting unit 100 as a whole has a generally oriented shape The antenna joint 101 and the inclined joint 103 can be integrally formed in a horizontal cross-section. The antenna joint 101 is arranged vertically in the left-right direction to be close to the back of the antenna device A, and the inclined joint 103 can be arranged to extend vertically to the rearward direction at the right end of the antenna joint 101 for a specified length.

[0064] The antenna connection end 101 is a portion that is tightly attached to the back or side of the antenna device A, and has a bolt through hole 106' that can be bolted in place by a fastening bolt (not shown). Figure 4 As shown, three bolt fastening ends 106 can be formed at the left and right ends of the antenna coupling end 101, spaced at a predetermined distance along the vertical direction. In the antenna clamping device 50 of one embodiment of the present invention, the antenna coupling end 101 is tightly attached to the back of the antenna device A and the bolt through hole 106' is through in the front-back direction. However, it is not limited to this. When the area of ​​the antenna coupling end 101 is larger than the area of ​​the back of the antenna device A, the bolt fastening end 106 can be bent and extended toward the side of the antenna device A to be tightly attached, and the bolt through hole 106' is through in the left-right direction.

[0065] Multiple reinforcing ribs 107 are provided between the inclined joint end 103 and the antenna joint end 101, which can strengthen the weight of the antenna device A or reduce mechanical fatigue caused by wind around the antenna device A, and improve durability.

[0066] A tilting guide 109 may be provided at the tilting joint end 103 to guide the tilting action of the tilting unit 100 on the outer side facing the inner side of the right side of the front end of the rotating unit 200. The tilting guide 109 may be machined in the form of a slot on a uniform circumference centered on the tilting shaft 140. Figure 5 As shown, the tilt guide portion 109 described above can be formed such that the tilt guide bolt 135, described later, is fixed to the end of the rotating unit 200 by passing through the tilt joint end 103 in the left-right direction.

[0067] At the same time, such as Figure 4 As shown, in the inclined coupling end 103, the inclined shaft 140 can extend towards the right side of the front end of the rotating unit 200, close to the inner side of the right side of the front end of the rotating unit 200, in such a way that it becomes the inclined center of the inclined unit 100. The inclined shaft 140 is inserted into a portion of the inner side of the rotating unit 200 (described later) in a shape-corresponding manner, and can become the inclined rotation operation center of the inclined unit 100. Furthermore, in relation to the rotating unit 200, it has a shape-corresponding surface in a wide area, and therefore can also indirectly guide the inclined rotation operation.

[0068] like Figure 4As shown, the tilting shaft 140 can combine the tilting unit 100 with the rotating unit 200 through the tilting coupling unit.

[0069] More specifically, the tilting unit can be formed by a tilting fixing bolt 140b, which fixes the tilting unit 100 in such a way that it is maintained after tilting and rotating at a preset angle. The tilting fixing bolt 140b can be a bolt that is fixed to the rotating unit 200 by passing through the tilting center hole 104 and the tilting shaft 140 described later in the tilting joint end 103.

[0070] However, the tilting unit does not necessarily have to be formed by the tilting fixing bolt 140b. That is, although not shown, a tactile stop structure (not shown) may be included inside the rotating unit 200. After being engaged with the tilting shaft 140, the tactile stop structure (not shown) allows the tilting unit 100 to rotate along one side or the other in the vertical direction, and stops if a specified external force is not provided at a specified angle. The tilting fixing bolt 140b can be a fastening unit for engaging the tilting unit 100 with the tactile stop structure (not shown).

[0071] More specifically, the inclined coupling unit not only functions as a fixing unit that connects the inclined shaft 140 to the rotating unit 200 via an inclined fixing bolt 140b passing through the inclined center hole 104 formed at the center of the inclined coupling end 103, but may also include: an inclined fixing bolt 140b; and a tactile stop structure (not shown), which is disposed inside the rotating unit 200 and connected to the inclined shaft 140 via the inclined fixing bolt 140b.

[0072] As described above, at least one inclined guide portion 109, machined in the form of a slot, can be formed on the same circumference with the center of the inclined connecting end 103 as a reference. The inclined guide portion 109 can be one of a plurality of slots machined on the same circumference facing the outer side of the inclined center hole 104. The inclined guide portion 109 guides the inclined rotation of the inclined unit 100, while the inclined guide bolt 135, which is connected to it, limits the amount of inclined rotation of the inclined unit 100. For example, when the inclined unit 100 rotates upward about the inclined fixing bolt 140b as the rotation center, the inclined guide bolt 135 is engaged at the lower end of the inclined guide portion 109 to limit the upward inclined rotation, but when the inclined unit 100 rotates downward about the inclined fixing bolt 140b as the rotation center, the inclined guide bolt 135 is engaged at the upper end of the inclined guide portion 109 to limit the downward inclined rotation.

[0073] The tilting dust plug 140a is detachably mounted on the outside of the tilting center hole 104 of the tilting connection end 103. In the tilting dust plug 140a, when the user needs to connect with the rotating unit 200 of the tilting unit 100 and adjust the tilt angle via the tactile stop structure described later, the tilting fixing bolt 140b can be accessed by opening the tilting center hole 104. Normally, it prevents foreign objects such as dust from flowing into the tilting center hole 104 from the outside.

[0074] On the other hand, such as Figure 4 As shown, one embodiment of the antenna clamping device 50 of the present invention may further include an inclined guide bolt 135, which is fastened to the rotating unit 200 by passing through the inclined guide portion 109 formed in the inclined joint end 103.

[0075] The tilting guide bolt 135 is fixed to the rotating unit 200. When the tilting unit 100 tilts and rotates at a specified angle in the vertical direction, it is locked against the inner sidewalls of one end and the other end of the tilting guide part 109, thereby physically limiting the tilting rotation of the tilting unit 100.

[0076] The slot of the tilt guide 109 is formed on the same circumference concentric with the tilt shaft 140, and the tilt unit 100 can be machined with a circumferential surface having a maximum upward tilt rotation of 40 degrees and a downward tilt rotation of 40 degrees. Therefore, the tilt unit 100 can tilt and rotate within a total tilt rotation angle range of 80 degrees in the vertical direction.

[0077] In the tilting unit 100 formed by the structure described above, when the antenna device A needs to tilt and rotate along the vertical direction at the antenna connection end 101, the tilting unit 100 and the rotation unit 200 are loosened by using the tilt fixing bolt 140b in the tilting connection unit. The tilting rotation amount is adjusted by applying manual force or an external force suitable for a tactile stop structure to the tilting unit 100. Then, the tilt fixing bolt 140b is used to completely fix the tilting rotation angle, thereby allowing the antenna device A to be tilted and rotated along the vertical direction.

[0078] On the other hand, such as Figure 4 and Figure 6 As shown, the rotating unit 200 may include: a tilting unit setting end 210, which is combined with the tilting unit 100 to tilt the tilting unit 100; and a rotating block 220, which forms a rotating shaft 230 that is inserted into the rotating shaft groove 331 formed in the arm unit 300.

[0079] The tilting unit setting end 210 is a portion that is set close to the tilting connection end 103 of the tilting unit 100, and is defined as the right side of the front end of the rotating block 220. In the case of the antenna clamping device 50 of one embodiment of the present invention, the tilting unit setting end 210 is provided on the right side of the rotating block 220, but when the tilting connection end 103 of the tilting unit 100 is provided in the opposite direction, the tilting unit setting end 210 may be provided on the left side of the rotating block 220.

[0080] like Figure 5 As shown, a tilting shaft mounting hole 240 is recessed in the center of the tilting unit mounting end 210 along the left-right direction, through which the tilting shaft 140 of the tilting unit 100 is inserted. The tilting shaft 140 of the tilting unit 100 can be inserted into the tilting shaft mounting hole 240. Inside the tilting shaft mounting hole 240, there may be a fixing hole (not shown) for fixing the tilting fixing bolt 140b, or a tactile stop structure (not shown) as a tilting connection unit may be provided.

[0081] On the other hand, such as Figure 5 As shown, an inclined guide bolt fixing hole 235' is formed on the outer side of the inclined shaft mounting hole 240 at the inclined unit mounting end 210, for inserting and fixing the end of the inclined guide bolt 135 of the inclined unit 100. An inclined guide bolt 135, which passes through the inclined guide portion 109 of the inclined unit 100 from the outside, is fastened to the inclined guide bolt fixing hole 235'. The operator can estimate the amount of tilt rotation based on the position of the inclined guide portion 109 relative to the tilt rotation of the inclined unit 100.

[0082] On the other hand, such as Figure 4 and Figure 6 As shown, in one embodiment of the antenna clamping device 50 of the present invention, the rotating unit 200 may further include a rotating shaft 230, which may be integrally formed with the lower side of the rear end of the rotating block 220 or the rotating shaft 230 may be manufactured separately and combined with the rotating block 220.

[0083] The rotating shaft 230 is a part that is inserted into the rotating shaft groove 331. It is a part that allows the rotating unit 200 to rotate in the left and right direction with the rotating shaft groove 331 as the center. The rotating shaft groove 331 is formed in the front end of the clamping arm 330 in the arm unit 300 in a circular hollow shape with an opening facing the upper side.

[0084] A rotation guide 209 may be provided at the rear end of the rotating block 220 to guide the rotating unit 200 to rotate in the left-right direction. The rotation guide 209 may be machined in the form of a slot on the same circumference centered on the rotating shaft 230. Figure 6 As shown, the rotation guide 209 described above can be formed such that the rotation guide bolt 235 (described later) is fixed to the arm unit 300 by passing through the rear end of the rotating block 220 in the vertical direction. The rotation guide 209 can perform the function of limiting the rotation amount of the rotating unit 200 by the rotation guide bolt 235 (described later) that passes through and is coupled to it.

[0085] Meanwhile, the rotating shaft 230 provided at the rear end of the rotating block 220 can be provided to extend downward from the lower surface of the rear end of the rotating block 220 by a predetermined length. The rotating shaft 230 is inserted into the rotating shaft groove 331 in a shape corresponding to the shape. The rotating shaft groove 331 is formed at the front end of the clamping arm 330 of the arm unit 300, which is described later, with an opening towards the upper side. It can serve as the center of rotational movement. Furthermore, in relation to the rotating shaft groove 331 of the clamping arm 330, it has a shape-corresponding surface in a wide area, thus indirectly guiding the rotational movement.

[0086] A rotation center hole 204 may be formed at the rear end of the rotating block 220. The rotation center hole 204 passes through the rear end of the rotating block 220 in the vertical direction and also passes through the center of the rotating shaft 230.

[0087] like Figure 4 As shown, the rotating shaft 230 can combine the clamping arm 330 of the arm unit 300 with the rotating unit 200 through the rotating coupling unit.

[0088] More specifically, the rotating unit can be formed by a rotating fixing bolt 230b, which fixes the rotating unit 200 in such a way that it is maintained after being rotated and adjusted at a preset angle. The rotating fixing bolt 230b can be a bolt that is fixed to the clamping arm 330 of the arm unit 300 by passing through the rotation center hole 204 and the rotating shaft 230.

[0089] Furthermore, similar to the tilting coupling unit described above, the rotary coupling unit is not necessarily formed by the rotary fixing bolt 230b, and may include a tactile stop structure (not shown). Hereinafter, the rotary coupling unit and the tilting coupling unit differ only in their installation positions. Both are structures that combine the tilting unit 100 with the rotary unit 200 and the rotary unit 200 with the arm unit 300 in the same manner. Therefore, the description of the tilting coupling unit will be used instead of its specific description.

[0090] On the other hand, such as Figure 4 As shown, one embodiment of the antenna clamping device 50 of the present invention may further include a rotation guide bolt 235 that is fastened to the front end of the clamping arm 330 of the arm unit 300 by passing through a rotation guide portion 209 formed in the rotation block 220.

[0091] When the rotating guide bolt 235 is fixed to the clamping arm 330 of the arm unit 300 to rotate the rotating unit 200 by a specified angle in the left and right direction, it is locked at one end and the inner sidewall of the other end of the rotating guide part 209, thereby performing the function of physically limiting the amount of rotation of the rotating unit 200.

[0092] The slot of the rotation guide 209 is formed on the same circumference concentric with the rotation shaft 230, and the rotation unit 200 can be machined with a circumferential surface having a maximum leftward tilt rotation of 40 degrees and a rightward tilt rotation of 40 degrees. Therefore, the rotation unit 200 can tilt and rotate in the left and right directions within a total tilt rotation angle range of 80 degrees.

[0093] On the other hand, the rotating side dust plug 230a is provided on the outside of the rotation center hole 204 of the rotating block 220 in a detachable manner. In the rotating side dust plug 230a, when the user needs to connect with and adjust the rotation angle of the arm unit 300 of the rotating unit 200 via the tactile stop structure described later, the rotating fixing bolt 230b can be accessed by opening the rotation center hole 204. Normally, it can prevent foreign objects such as dust from flowing into the interior of the rotation center hole 204 from the outside.

[0094] In the rotating unit 200 formed by the structure described above, when the antenna device A combined with the tilting unit 100 needs to be rotated in the left and right direction, the rotation amount is adjusted by applying manual force or an external force suitable for a tactile stop structure to the rotating unit 200 while the connection between the rotating unit 200 and the arm unit 300 is loosened by using the rotating fixing bolt 230b in the rotating unit. Then, the rotating unit 200 is completely fixed at the corresponding rotation angle by using the rotating fixing bolt 230b, thereby allowing the antenna device A to be rotated and adjusted in the left and right direction.

[0095] On the other hand, a rotation angle label 250 may be attached to the upper side of the rotating block 220 corresponding to the front or rear end of the rotating guide portion 209. The rotation angle label 250 indicates the position of the rotating guide bolt 235 that moves relatively within the slot from the reference point by an angle.

[0096] The reference point related to the position of the rotating guide bolt 235 is the horizontal state in which the rotating unit 200 has not rotated, and is represented by "0 degrees". For rotation in the left direction and rotation in the right direction, the rotation angle can be represented by 5-degree angle intervals or 10-degree angle intervals, respectively.

[0097] Figure 7 To show Figure 2An exploded 3D view of the arm unit in the structure.

[0098] like Figure 7 As shown, the arm unit 300 may include: an outer mounting block 310 configured to be in close contact with one side of the outer peripheral surface of the pole 1; an inner mounting block 320 configured to be in close contact with the other side of the outer peripheral surface of the pole 1 and fixed to the outer mounting block 310 by at least one fixing bolt 325; and a clamping arm 330 extending a predetermined length from the inner mounting block 320 in a direction orthogonal to the pole 1, forming a front end portion having a rotating shaft groove 331.

[0099] The outer mounting block 310 is made of stainless steel and can form a skeleton. An outer fitting groove 343 can be formed in the outer mounting block 310 as a part that substantially corresponds to the shape of one side of the outer peripheral surface of the rod 1. Although not shown, the outer fitting groove 343 is provided on a support block (not shown) made of a high-friction material, and is combined with the rod 1 in a pattern substantially disposed between the outer mounting block 310 and the rod 1, thereby preventing gaps from forming between the outer mounting block 310 and the closely attached rod 1.

[0100] At least one outer bolt through hole 311 can be formed at both ends of the outer mounting block 310 along the vertical direction to allow the fixing bolt 325 to pass through. The outer mounting block 310 is formed of a hollow hexahedral metal material, and the outer bolt through hole 311 can be formed at corresponding positions on the front and rear faces, so that the fixing bolt 325 can be completely passed through along the front-rear direction.

[0101] After the outer mounting block 310, support block 340 and inner mounting block 320 are tightened by the fixing bolt 325 passing through the inner bolt through hole 321 and the outer bolt through hole 311 in sequence from the inner mounting block 320 side, they are firmly tightened by the fastening nut 360, thereby stably supporting the antenna device A.

[0102] Among them, such as Figure 7 As shown, the fastening nut 360 can be fastened to the end of the fixing bolt 325 exposed on the rear side of the outer mounting block 310. Although not shown, it can also be concealed and fastened to the space between the front and rear sides of the outer mounting block 310, making it difficult for a third party to disassemble it at will.

[0103] The outer fitting groove 343, which is substantially in close contact with one side of the outer peripheral surface of the rod 1 in the structure of the outer mounting block 310, can be recessed in a shape corresponding to the outer peripheral surface of the rod 1, thereby increasing the contact area for the rod 1, which has a circular horizontal cross-section. At the same time, the outer fitting groove 343 can be serrated in a manner that forms multiple serrated ribs, so that it can be pressed against the outer peripheral surface of the rod 1 by the fastening force of the fixing bolt 325 and the fastening nut 360, thereby generating stronger friction.

[0104] Meanwhile, an inner groove 323 corresponding to the outer groove 343 of the outer mounting block 310 can be formed on the outer side of the inner mounting block 320, that is, the surface that is substantially in close contact with the support rod 1. For the purpose of supporting rigidity, the inner mounting block 320 is made of stainless steel. Regardless of this, multiple serrations can be formed in the inner groove 323 to prevent gaps from forming between the inner groove 323 and the support rod 1.

[0105] The inner mounting block 320 and the clamping arm 330 can be formed as one piece. In the inner mounting block 320, the area in all directions (i.e., the front area) is relatively larger than the area in all directions occupied by the clamping arm 330. Conversely, according to the embodiment, the front end of the clamping arm 330 can be formed from the gripping rod 1 at different intervals.

[0106] When the clamping arm 330 is relatively short, the load of the antenna device A can be adequately supported by the integral molding method of the connection between the inner mounting block 320 and the clamping arm 330. However, if... Figure 5 As shown, when the clamping arm 330 is relatively long, at least one reinforcing rib 380 can be formed at the connection between the inner mounting block 320 and the clamping arm 330.

[0107] Figure 8 for Figure 2 The top view is a top view showing the rotation state through the rotating unit. Figure 9 for Figure 2 The side view shows the tilted state through the tilting unit.

[0108] Reference Figure 8 and Figure 9 The rotation and tilting actions of the antenna clamping device 50 according to an embodiment of the present invention will be described in more detail below.

[0109] First, such as Figure 8As shown, regarding the rotation action, when the antenna device A is engaged with the front end of the tilting unit 100, if a specified external force is applied to the antenna device A or the rotation unit 200, the rotation can be achieved by disengaging the rotation unit and rotating in the left-right direction, thereby securing it firmly at a preset rotation angle position through the rotation unit.

[0110] In this case, a predetermined torque based on the mast 1 is applied to the rotating unit 200 including the antenna device A. The outer groove 343 and the inner groove 323 formed on the arm unit 300 can be formed by sawing and are firmly attached to the mast 1 to prevent movement during rotation.

[0111] Next, as Figure 9 As shown, for the tilting action, when the antenna device A and the front end of the tilting unit 100 are combined, if a specified external force is applied to the antenna device A or the tilting unit 100, the tilting unit 100, with the tilting shaft 140 as a reference, causes the tilting guide bolt 135 to tilt relative to each other within the slot range limited by the tilting guide part 109.

[0112] After adjusting the tilt angle of antenna device A, the tilt unit 100 can be securely fixed at a preset rotation angle position using the tilt coupling unit.

[0113] exist Figure 8 and Figure 9 The unspecified reference numerals 160 and 260 shown are fastening units for securing the ends of the inclined fixing bolt 140b and the rotating fixing bolt 230b, respectively. The fastening units 160 and 260 can be provided in the form of a fixing bushing, which has an internal thread (not shown) that is fastened to the external thread (not shown) formed on the outer peripheral surface of the end of the inclined fixing bolt 140b and the end of the rotating fixing bolt 230b.

However, the embodiments of the present invention are not limited to the embodiment described above, and modifications can be made and the invention can be implemented within the equivalent scope by those skilled in the art. Therefore, the true scope of the present invention is defined by the scope of the claims.
