Description

Technical Field

[0001] The present invention relates to an antenna clamping device, and more specifically, to an antenna clamping device configured to improve operability by simply inserting and mounting a heavy antenna device into the upper end of a support rod without a separate fixing device. Background Technology

[0002] Wireless communication technologies, such as MIMO (Multiple Input Multiple Output), are techniques that use multiple antennas to greatly increase data transmission capacity. In this technology, the transmitter sends different data through each transmitting antenna, while the receiver distinguishes the transmitted data through appropriate signal processing.

[0003] Therefore, increasing the number of transmitting and receiving antennas while simultaneously increasing channel capacity allows for the transmission of larger amounts of data. For example, increasing the number of antennas to 10 would ensure approximately 10 times the channel capacity compared to a current single-antenna system using the same frequency band.

[0004] 4G LTE-advanced uses up to eight antennas, and products with 64 or 128 antennas are currently being developed in the pre-5G stage. It is predicted that 5G will use base station equipment with an even greater number of antennas, a technology known as Massive MIMO. Current cell operation is two-dimensional, but by introducing Massive MIMO technology, 3D beamforming can be achieved, hence it is also called FD-MIMO (Full Dimension).

[0005] In Massive MIMO technology, the number of transmitters and filters increases along with the number of ANTs (antennas). Even so, the reality is that rental costs or space constraints at installation sites have led to the manufacture of RF components (Antenna / Filter / Power Amplifier / Transceiver, etc.) that are lightweight and cheaper. However, since Massive MIMO requires high power to expand coverage, the power consumption and heat generated by this high power output negatively impact weight and size reduction.

[0006] In particular, when installing MIMO antennas that combine RF and digital components in a stacked structure within a limited space, the necessity of compacting and miniaturizing the multi-layered structure that constitutes the MIMO antenna becomes apparent in order to maximize ease of installation and space utilization. This is especially relevant given the strong demand for free orientation of antenna devices mounted on a support pole. Summary of the Invention

[0007] (The problem to be solved)

[0008] The present invention is proposed to solve the technical problems described above, and its purpose is to provide an antenna clamping device that can be directly installed and set at the upper end of the opening of the support rod, and can be firmly fixed to the inner space of the upper end of the support rod without a separate fixing device.

[0009] (Solutions)

[0010] An embodiment of the antenna clamping device of the present invention includes: an antenna clamping part, on which an antenna device is mounted at a front end and configured to perform at least one of tilting rotation or rotational rotation to set the directivity of the antenna device, and a rear end inserted into and fixed to the upper inner side of an opening of a support rod; an insertion-type clamping part, disposed on the upper inner side of an opening of the support rod, mediating the insertion and fixing of the antenna clamping part, and being compressed and fixed to the inner circumferential surface of the support rod; and a support bracket part, configured to be fixed to the outer circumferential surface of the support rod, and fixing and supporting the lower end of the antenna clamping part.

[0011] Here, the insertion-type clamping part may include: a clamping body, which is inserted into and fixed to the upper inner side of the opening of the support rod, and has a hollow internal space, wherein the internal space is divided into an upper space and a lower space by a partition plate; a fixing bolt, configured to pass through the internal space of the clamping body vertically; and a pair of locking pressure plates, which are linked to the rotation of the fixing bolt to fix the clamping body by pressing the inner circumferential surface of the support rod.

[0012] In addition, the insertion clamping part may also include a fixing nut, which is inserted into the outer peripheral surface of the fixing bolt, and the fixing bolt is rotated upward or downward in the upper space and the lower space of the clamping body in a rotational direction.

[0013] In addition, the fixing nut is inserted into the outer peripheral surface of the fixing bolt located in the upper space, and can be supported and fastened to the top of the zoning plate.

[0014] Additionally, the pair of locking pressure plates are located in the lower space within the internal space of the clamping body; and a pair of through portions in the clamping body that can form openings allow the pair of locking pressure plates to move horizontally to contact the inner circumferential surface of the support rod.

[0015] In addition, the outer surfaces of the pair of locking pressure plates that contact the inner circumferential surface of the support rod are serrated to increase grip.

[0016] In addition, the insertion-type clamping part may also include a lifting plate, which intervenes in and is linked to the outer periphery of the lower end of the fixing bolt located in the lower space within the internal space of the clamping body.

[0017] In addition, the lifting plate is inserted into the lower end of the fixing bolt located in the lower space of the internal space of the clamping body, and can be clamped and supported by a bolt head with a diameter relatively larger than that of the fixing bolt.

[0018] In addition, the outer surface of the lifting plate is inclined upward; the inner surface of the pair of locking pressure plates is inclined to be parallel to the outer surface of the lifting plate; the outer surface of the pair of locking pressure plates can be formed as a curved surface parallel to the inner circumferential surface of the support rod.

[0019] In addition, the lower space in the internal space of the clamping body is enclosed by a lower plate; the lower plate may have a pair of guide ribs that guide the lifting plate, which moves up and down by moving up and down through the fixing bolts.

[0020] In addition, the pair of locking pressure plates are positioned so that their upper surfaces are tightly attached to the lower part of the partition plate, while the lower part is supported by the upper surface of the lower plate. They can be configured to move horizontally between the partition plate and the lower plate by the lifting and lowering of the lifting plates.

[0021] In addition, the upper end of the clamping body forms a locking flange that extends outward in a radial shape and has an outer diameter larger than the inner diameter of the upper end of the support rod; a lower friction ring pad that generates friction with the lower part of the rear end of the clamping part for the antenna may also be provided on the upper surface of the locking flange.

[0022] Additionally, the rear end of the antenna clamping part may have an upper friction ring pad that contacts the lower friction ring pad surface of the clamping body to generate friction.

[0023] Additionally, a mounting shaft with a downwardly recessed mounting groove is formed at the rear end of the antenna clamping part; the antenna clamping part can be inserted into the upper space within the internal space of the clamping body to fix the mounting shaft.

[0024] In addition, the upper end of the fixing bolt passes through the mounting shaft and can be threaded into the inner side of the mounting groove.

[0025] Additionally, the rear end of the antenna clamp may have a bolt fastening part that is threaded to the support bracket.

[0026] Additionally, the support bracket may include: a fastening plate extending vertically along one side of the outer periphery of the support rod; a U-bolt penetrating a U-bolt fastening hole formed in the fastening plate and engaging with the other side of the outer periphery of the support rod to surround the outer periphery of the support rod; and a clamping plate extending upward toward the fastening plate and clamping the bolt fastening portion of the antenna clamping part.

[0027] In addition, the antenna clamping part can be fixed by at least one fixing bolt that passes through the fastening plate and is fastened to the bolt fastening part.

[0028] In addition, the fastening plate and the fastening plate are positioned so that when the antenna clamping part is inserted into the internal space of the clamping body fixed to the upper end of the support rod and supported, they can be located in a position where the bolt fastening part and the fastening plate face each other.

[0029] Another embodiment of the antenna clamping device of the present invention includes: an antenna clamping part, on which an antenna device is mounted at a front end and configured to perform at least one of tilting rotation or rotational rotation to set the directivity of the antenna device, and a rear end inserted into and fixed to the upper inner side of an opening of a support rod; an insertion-type clamping part, disposed on the upper inner side of an opening of the support rod, mediating the insertion and fixing of the antenna clamping part, and being compressed and fixed to the inner circumferential surface of the support rod; wherein the insertion-type clamping part may include: a clamping body, which is inserted and fixed to the upper inner side of an opening of the support rod and has a hollow internal space, and the internal space is divided into an upper space and a lower space by a partition plate; a fixing bolt, configured to penetrate vertically through the internal space of the clamping body; and a pair of locking pressure plates, linked to the rotational action of the fixing bolt, to fix the clamping body by pressing the inner circumferential surface of the support rod.

[0030] (The effect of the invention)

[0031] An embodiment of the antenna clamping device according to the present invention can achieve the following various effects:

[0032] First, compared to existing methods, it significantly reduces the number of components used for clamping antennas, thereby saving costs.

[0033] Secondly, in order to fix the antenna clamping part, the insertion type clamping part is located in the internal space of the support rod, which has the effect of preventing it from affecting the appearance of the outside.

[0064] Hereinafter, an embodiment of the antenna clamping device of the present invention will be described in detail with reference to the accompanying drawings. When affixing reference numerals to the components in the various drawings, care should be taken to ensure that the same components have the same reference numerals as much as possible, even if they are labeled in different drawings. Furthermore, in the description of embodiments of the present invention, detailed descriptions of related known structures or functions will be omitted if it is determined that such detailed descriptions would hinder understanding of the embodiments of the present invention.

[0065] In the description of components in embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. These terms are merely used to distinguish one component from another and should not be used to limit the nature or order of the components. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, shall have meanings corresponding to those conventionally understood by one of ordinary knowledge in the art to which this invention pertains. Terms identical to those commonly used and defined in dictionaries shall be interpreted as having the same meaning as in related art texts, and shall not be defined in an ideal or overly formal sense unless expressly defined herein.

[0066] Figure 1 This is a perspective view and a partially cut perspective view of an antenna clamping device according to an embodiment of the present invention; Figure 2 yes Figure 1 An exploded 3D diagram.

[0067] like Figure 1 and Figure 2 As shown, an antenna clamping device according to an embodiment of the present invention includes: an antenna clamping part 10, an antenna device (not shown) is mounted at the front end and configured to rotate during tilting or rotation to set the directivity of the antenna device; an insertion clamping part 100, the medium antenna clamping part 10 is inserted into and fixed to the upper end of a support rod 1; and a support bracket part 50, which fixes and supports the lower end of the antenna clamping part 10.

[0068] The antenna clamping part 10 is actually used for mounting medium antenna equipment, such as... Figure 1 and Figure 2 As shown, it can be configured to tilt or rotate, thereby setting the directivity of the antenna device.

[0069] More specifically, the antenna clamping part 10 may include: a tilting unit 11, which mounts the antenna device at the front end and tilts and rotates up and down by a predetermined angle about the tilting axis (TS, Tilting Shaft) when the antenna device is mounted; a rotating unit 12, which is connected to the rear end of the tilting unit 11 and rotates the antenna device left and right by a predetermined angle about the rotating axis (RS, Rotating Shaft); and a connecting unit 13, which is connected to the rear end of the rotating unit 12 and is used for inserting and fixing the medium to the support rod 1.

[0070] That is, the antenna device installed in the antenna clamping part 10 adjusts its directivity by tilting and rotating in the vertical direction using the tilting unit 11, and simultaneously adjusts its directivity by rotating in the horizontal direction using the rotating unit 12, thereby further improving the reliability of the signal quality of the antenna device.

[0071] like Figure 1 and Figure 2 As shown, in the structure of the antenna clamping part 10, the upper part of the rear end 15 of the connecting unit 13 extends horizontally toward the upper end of the support rod 1, and a mounting shaft 17 with a mounting groove 16 extending downward is formed in the extended rear end 15 of the connecting unit 13.

[0072] The mounting shaft 17 of the connecting unit 13 is inserted into the internal space of the insertion-type clamping part 100 provided at the upper end opening of the support rod 1 and installed onto the upper space side. The upper end of the fixing bolt 140 of the insertion-type clamping part 100, which is exposed and extends through the upper side of the mounting groove 16 (not shown), can be tightened and fixed using a fastening nut. Simultaneously, the mounting shaft 17 of the connecting unit 13 is sized to match the upper space within the internal space of the insertion-type clamping part 100, preventing gaps (or movement) in the overall structure of the antenna clamping part 10 installed and fixed to the insertion-type clamping part 100.

[0073] At the same time, such as Figure 1 and Figure 2 As shown, a bolt fastening portion 18 is provided on the lower rear end of the connecting unit 13. The bolt fastening portion 18 is closely attached to the support bracket portion 50 (described later) to fasten and fix it to the support bracket portion 50. At least one bolt fastening hole 19 is formed in the bolt fastening portion 18. The bolt fastening hole 19 of the bolt fastening portion 18 can be connected to the bolt fastening portion 18 formed at the rear end of the connecting unit 13 of the antenna clamping portion 10 by the action of the fixing bolt 58 of the support bracket portion 50 passing through and fastening it.

[0074] like Figure 1 and Figure 2 As shown, in order to securely fix the antenna clamping part 10 in the form of a single tube mounted on the upper end of the support rod 1, the antenna clamping part 10 can act as a medium for this connection.

[0075] Although not shown, the antenna clamping part 10 is typically attached to the support rod 1 after a separate mounting bracket or mounting arm surrounding the outer periphery of the support rod 1 is first installed. However, this arrangement exposes the mounting bracket or mounting arm to the outside of the support rod 1, affecting the aesthetics of the outside of the support rod 1 where the antenna equipment is mounted. Furthermore, in order to support the relatively heavy antenna clamping part 10 and antenna equipment in the direction of gravity, a complex and robust structural combination is required.

[0076] An antenna clamping device according to an embodiment of the present invention can minimize the number of components that may affect the aesthetic appearance of the outer side of the support rod 1. Instead, a portion of the structure that can fix and support the antenna clamping part 10 is hidden inside the upper opening of the support rod 1, while achieving a more robust support structure.

[0077] That is, such as Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the antenna clamping device only has a support bracket 50, which is a simple structure for preventing the antenna clamping part 10 from having a gap (movement) in the left-right direction on the outer peripheral surface spaced a predetermined distance from the upper end of the support rod 1. Additionally, an insertion-type clamping part 100 is installed inside the opening at the upper end of the support rod 1 to connect and fix the medium to the antenna clamping part 10. Here, after the rear end portion 15 of the connecting unit 13 is simply installed and fixed to the upper end of the insertion-type clamping part 100, the antenna clamping part 10 can be securely fixed using the support bracket 50.

[0078] Figure 3 Is Figure 1 The structure shows a perspective view of the arrangement of the support rod for the insertion clamping part and the support bracket part; Figure 4 Is Figure 3 An exploded perspective view of the structure shows the configuration of the insertion-type clamping part; Figure 5 Is Figure 3 The structure shows an exploded perspective view of the arrangement of the support bracket.

[0079] like Figure 3 and Figure 4 As shown, in one embodiment of the antenna clamping device of the present invention, before fixing the antenna clamping part 10 to the support rod 1, the insertion type clamping part 100 is inserted and fixed in the upper opening of the support rod 1, and the support bracket part 50 can be temporarily fixed on the outer peripheral surface of the support rod 1 at a predetermined distance from the upper end of the support rod 1 downward.

[0080] Here, as Figure 5 As shown, the support bracket portion 50 may include: a fastening plate 51, which extends vertically and is disposed on one side of the outer periphery of the support rod 1; a U-bolt 53, which passes through the U-bolt fastening hole 52 formed in the fastening plate 51 and is coupled to the other side of the outer periphery of the support rod 1 to surround the outer periphery of the support rod 1; and a mating plate 56, which extends upward toward the fastening plate 51 and is mated to the bolt fastening portion 18 of the antenna clamping portion 10.

[0081] The fastening plate 51 includes a generally arc-shaped curved surface that is close to the outer periphery of the support rod 1, and U-bolt fastening holes 52 can be formed on one side and the other side, through which the front end of the U-bolt 53 passes.

[0082] With the elastic washer 55 inserted in front of the fastening plate 51, the front end of the U-bolt 53, which passes through the U-bolt fastening hole 52, is securely tightened by the U-bolt fastening nut 54. The tightening force of the U-bolt fastening nut 54 secures the U-bolt 53 to the outer circumference of the support rod 1.

[0083] The mating plate 56 extends upward toward the fastening plate 51, but it is not necessary for it to extend upward; it can also extend downward. Simultaneously, a bolt through-hole 57 extending in the rear-to-rear direction can be formed in the mating plate 56. By forming the bolt through-hole 57 in the mating plate 56, and fastening it to the bolt fastening hole 19 of the bolt fastening part 18 formed on the lower rear end of the connecting unit 13 in the structure of the antenna clamping part 10 by a fixing bolt 58 passing through the rear of the mating plate 56, the rear end of the connecting unit 13 of the antenna clamping part 10 can be securely fixed.

[0084] Here, as Figure 1 and Figure 2 As shown, when the antenna clamping part 10 is inserted into the upper space of the clamping body 110 of the insertion type clamping part 100 fixed to the upper end of the support rod 1 and is supported, the fastening plate 51 and the fastening plate 56 are preferably located at the position where the bolt fastening part 18 and the fastening plate 56 face each other.

[0085] Figure 6a and Figure 6b Is Figure 3 The structure shown is an exploded perspective view of the external and internal structures of the insertion-type clamping part. Figure 7 It is along Figure 3 A cut-out 3D image obtained from the BB line; Figure 8 As along Figure 3 The cut-out perspective view taken from the BB line is an exploded perspective view showing the exterior of the support rod;

[0086] Figure 9a and Figure 9b Is Figure 3 A cross-sectional view showing the operating mode of the locking pressure plate is shown in the structure of the insertion type clamping part.

[0087] In one embodiment of the antenna clamping device of the present invention, such as Figures 6a to 9b As shown, the insertion-type clamping part 100 may include: a clamping body 110, which is inserted into and fixed to the upper inner side of the opening of the support rod 1, and has a hollow internal space, which is divided into an upper space and a lower space by a partition plate 120; a fixing bolt 140, which is configured to pass through the internal space of the clamping body 110 vertically; and a pair of locking pressure plates 180a and 180b, which are linked to the rotation of the fixing bolt 140 to fix the clamping body 110 by pressing the inner circumferential surface of the support rod 1.

[0088] like Figures 6a to 9b As shown, the clamping body 110 is inserted into the inner circumferential surface of the upper opening 1a of the support rod 1, and is formed into a tube shape with an internal space. Moreover, the internal space can be divided into an upper space and a lower space by the partition plate 120.

[0089] The upper end of the clamping body 110 may have an outer diameter larger than the inner diameter of the upper end of the support rod 1, and may have a radially extending engagement flange 125. Thus, the clamping body 110 can be inserted into and installed inside the upper opening 1a of the support rod 1 by engaging the lower surface of the engagement flange 125 against the upper end face of the support rod 1. At this time, the outer peripheral surface of the clamping body 110 may be configured to closely adhere to or be close to the inner peripheral surface of the upper opening 1a of the support rod 1.

[0090] Meanwhile, a lower friction ring pad 200 may be provided on the upper surface of the engaging flange 125 formed on the upper end of the clamping body 110, which generates friction with the lower part of the rear end 15 of the antenna clamping part 10.

[0091] Multiple screw fastening holes 190 are formed downward on the upper end face of the engaging flange 125 of the clamping body 110, and multiple screw through holes 290 are also formed in the lower friction ring pad 200 in the vertical direction. The lower friction ring pad 200 can be fastened to the screw fastening holes 190 formed on the upper end face of the engaging flange 125 by the countersunk screw component 210 passing through the screw through holes 290 from the upper side to the lower side of the lower friction ring pad 200.

[0092] In addition, such as Figure 1 As shown, in the structure of the antenna clamping part 10, the upper friction ring pad 20, which generates frictional force by contacting the lower friction ring pad 200 surface, can be fastened and fixed under the rear end 15 of the connecting unit 13 (more specifically, under the periphery of the mounting shaft 17) by the countersunk screw part 21.

[0093] Since the upper friction ring pad 20 of the antenna clamping part 10 and the lower friction ring pad 200 of the insertion type clamping part 100 are in surface contact with each other to generate a predetermined friction force, the phenomenon of movement due to small vibrations transmitted from the outside (e.g., movement due to wind) can be prevented.

[0094] On the other hand, the internal space of the clamping body 110 can be divided into an upper space located at the top and a lower space located at the bottom by a partition plate 120 that is horizontally arranged as a whole in its middle part.

[0095] The upper space of the clamping body 110 opens upwards, while the lower space can be closed by the lower plate 130. The upper and lower spaces of the clamping body 110 can be connected to each other through a fixing bolt through hole (not shown in the figure) through which the fixing bolt 140 passes.

[0096] Here, the fixing bolt 140 is configured to pass through the fixing bolt through hole formed in the clamping body 110, and can be configured in the upper and lower spaces of the clamping body 110 as a whole.

[0097] Meanwhile, the fixing bolt 140 may also include a fixing nut 150, which is inserted into the outer peripheral surface of the fixing bolt located in the upper space of the clamping body 110, and the fixing bolt 140 is rotated and moved upward or downward in the rotational direction in the upper and lower spaces of the clamping body 110 as a whole.

[0098] More specifically, the fixing nut 150 intervenes on the outer peripheral surface of the fixing bolt located in the upper space, and can be supported and fastened to the top of the partition plate 120. At this time, a fixing washer 160 is also inserted between the fixing nut 150 and the top of the partition plate 120 to prevent the fixing bolt 140 from loosening arbitrarily. For reference, if the fixing bolt 140 is loosened arbitrarily, there is a possibility that the fixing bolt 140 may move downward. If the fixing bolt 140 moves downward, there is a concern that the fixing force of the clamping body 110 fixed to the inner peripheral surface of the upper opening 1a of the support rod 1 by the locking pressure plates 180a and 180b may be weakened.

[0099] On the other hand, a pair of through portions 115, which are cut open on the outer peripheral surface of the clamping body 110, are formed to communicate with the lower space in its internal space. The pair of through portions 115 perform the function of a pair of locking pressure plates 180a and 180b located in the lower space in the internal space of the clamping body 110, which move horizontally to contact the channel on the inner peripheral surface side of the support rod 1.

[0100] In an embodiment of the antenna clamping device of the present invention, the insertion type clamping part 100 may further include a lifting plate 170, which is inserted into and linked to the outer periphery of the lower end of the fixing bolt 140 located in the lower space of the internal space of the clamping body 110.

[0101] Here, the fixing bolt 140 has a bolt head 145 with a relatively larger diameter at its lower end. The lifting plate 170 is held and supported upward by the bolt head 145 of the fixing bolt 140 located in the lower space within the clamping body 110. Thus, when the fixing bolt 140 moves up and down within the clamping body 110 via the fixing nut 150, the lifting plate 170 can also move in the up and down direction in a coordinated manner.

[0102] The lifting plate 170 is located in the lower space of the internal space of the clamping body 110 between a pair of locking pressure plates 180a and 180b, and is configured such that one side contacts one of the locking pressure plates 180a and 180b, and the other side contacts the other of the locking pressure plates 180b. Therefore, when it moves in conjunction with the rotation of the fixing bolt 140 in the vertical direction as described above, each locking pressure plate 180a and 180b can be moved horizontally in the lower space.

[0103] Therefore, the outer surfaces of the lifting plate 170 that contact the pair of locking pressure plates 180a and 180b are inclined upwards, while the inner surfaces of the pair of locking pressure plates 180a and 180b are inclined parallel to the outer surface of the lifting plate 170. Thus, when the lifting plate 170 rises, the locking pressure plates 180a and 180b, which contact the inclined outer surfaces of the lifting plate 170, are pushed outwards against each other and pressed against the inner circumferential surface of the upper opening 1a of the support rod 1. Here, the outer surfaces of the pair of locking pressure plates 180a and 180b may be serrated to increase the adhesion force against the inner circumferential surface of the upper opening 1a of the support rod 1.

[0104] On the other hand, the outer surfaces of the pair of locking pressure plates 180a and 180b can be formed by curved surfaces parallel to the inner circumferential surface of the support rod 1. That is, the support rod 1 is configured as a circular hollow tube shape, and its inner circumferential surface forms a circular curved surface. In order to maximize the contact area through the pair of locking pressure plates 180a and 180b, the outer surfaces of the pair of locking pressure plates 180a and 180b are preferably formed in a shape corresponding to the inner circumferential surface of the support rod 1.

[0105] The lifting plate 170 is configured to move in the up-down direction in conjunction with the up-down movement of the fixing bolt 140, and can be raised and lowered by receiving guidance from a pair of guide ribs 131 formed on the lower plate 130 located below it.

[0106] A pair of guide ribs 131 may be formed at intervals to roughly correspond to the distance between the two outer sides of the lifting plate 170 that are not in contact with the pair of locking pressure plates 180a, 180b.

[0107] Refer to the attached figures (especially, Figure 9a and Figure 9b The following is a brief description of the operation process of an embodiment of the antenna clamping device of the present invention configured as described above.

[0108] First, such as Figure 9a As shown, the insertion-type clamping part 100 is inserted into and fixed to the upper opening 1a of the support rod 1.

[0109] Then, as Figure 9b As shown, if the fixing bolt 140 is rotated upward from the internal space of the clamping body 110 by rotating the fixing nut 150 in the locking direction, the lifting plate 170 inserted in the bolt head 145 of the fixing bolt 140 rises upward by the guidance of a pair of guide ribs 131. As the lifting plate 170 rises upward, a pair of locking pressure plates 180a and 180b pass through a pair of through portions 115 and are pushed outward. At the same time, the outer surfaces of the pair of locking pressure plates 180a and 180b, which are machined with serrations, are firmly attached to the inner circumferential surface of the support rod 1, thereby fixing the clamping body 110 to prevent it from being arbitrarily separated from the support rod 1.

[0110] The above description of one embodiment of the antenna clamping device of the present invention includes an antenna clamping part 10, an insertion clamping part 100, and a support bracket part 50. However, embodiments in which the support bracket part 50 is omitted are also possible. An embodiment in which the support bracket part 500 is omitted and only the antenna clamping part 10 and the insertion clamping part 100 are used can be defined as another embodiment of the antenna clamping device of the present invention.

[0111] The antenna clamping device of the present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments and other embodiments of the present invention are not limited to the one described above, but can certainly be modified and implemented by those skilled in the art. Therefore, the true scope of the present invention should be defined by the scope of the claims.
