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, as the number of antennas (ANTs) increases, the number of transmitters and filters also increases accordingly. 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, and to reduce costs. MIMO requires high output for coverage expansion, and the power consumption and heat generated by this high output become negative factors for reducing weight and size.

[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] The purpose of this invention is to provide an antenna clamping device that increases the degree of freedom in setting up a mast, which is subject to many space constraints, thereby improving operability.

[0019] Furthermore, the aforementioned steel reinforcement unit can be selectively set by considering factors such as the weight of the antenna device combined with the aforementioned tilting unit and the fatigue strength of the connection between the aforementioned inner mounting block and the aforementioned clamping arm based on the length of the aforementioned clamping arm.

[0020] Furthermore, at the front end of the clamping arm where the aforementioned mounting space is formed, at least one rotation guide portion can be machined in the form of a slot to guide the rotation of the aforementioned rotating unit.

[0021] Furthermore, the aforementioned rotary guide portion may include: at least one rotary guide groove machined on a circumference concentric with the aforementioned hinge point; and a rotary guide bolt extending from the outside through at least one of the aforementioned rotary guide grooves to fix it to the aforementioned rotary unit.

[0022] Furthermore, a rotation angle label may be attached to the front end of the clamping arm, the rotation angle label indicating the position of the rotary guide bolt moving within the rotary guide groove from the reference point by an angle.

[0023] Furthermore, the aforementioned rotating unit may include: a tilting unit mounting end, which is combined with the tilting unit to tilt the tilting unit; a rotating block, which is inserted into the mounting space of the arm unit; and a connecting block, which is used to connect the tilting unit mounting end with the rotating block.

[0024] Furthermore, a rotation brake pad can be formed between the rotating block and the arm unit, and an tilt brake pad can be formed between the tilt unit mounting end and the tilt unit.

[0025] Furthermore, a rotating side pad mounting groove can be formed on the top of the rotating block, and the rotating side pad mounting groove is combined with the rotating brake pad in a shape-corresponding manner. An inclined side pad mounting groove can be formed on the inner side of the inclined unit mounting end, and the inclined side pad mounting groove is combined with the inclined brake pad in a shape-corresponding manner.

[0026] Furthermore, multiple brake protrusions can be machined in a protruding manner on the top of the aforementioned rotary brake pad and on the inner side of the aforementioned inclined brake pad.

[0027] Furthermore, the two inclined unit mounting ends are spaced apart from each other so that they extend from the left and right ends of the connecting block toward the inclined unit respectively.

[0030] Furthermore, an angle label may be attached to the outer surface of the aforementioned tilt block, the angle label indicating the position of the tilt guide bolt moving within the aforementioned tilt guide groove from the reference point.

[0031] Furthermore, the aforementioned tilting unit may also include an extended connection portion, which is used to extend the connection between the antenna connection end and the tilting block in the left-right direction.

[0032] Furthermore, the aforementioned antenna connection end is in close contact with multiple locations on the back and side of the aforementioned antenna device in a surface-contact manner, and can be fastened and fixed by fastening holes formed at multiple locations on the back and side of the aforementioned antenna device using fastening units as a medium.

[0092] Hereinafter, an embodiment of the antenna clamping device of the present invention will be described in detail with reference to the accompanying drawings. 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.

[0093] In describing the structural elements of embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. 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. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Terms whose meanings are defined in commonly used dictionaries are consistent with their meanings within the context of the relevant art and should not be construed as having an ideal or overly formal meaning unless explicitly defined herein.

[0094] 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 3D view of the inclined unit in the structure. Figure 5 To show Figure 2 An exploded 3D view of the rotating unit in the structure. Figure 6 To show Figure 2 An exploded 3D view of the arm unit in the structure.

[0095] like Figures 1 to 6 As shown, one embodiment of the antenna clamping device 50 of the present invention includes: an arm unit 300, which is horizontally coupled to a support rod 1, the support rod 1 being vertically fixed to the ground in the up-down direction; a rotation unit 200, which is coupled to the arm unit 300 and is coupled to the arm unit 300 in a manner that allows it to rotate along a pivot in the left-right direction; and a tilting unit 100, which is coupled to the rotation unit 200, acts as a medium for the coupling of the antenna device A, and is coupled to the rotation unit 200 in a manner that allows it to tilt and rotate in the up-down direction.

[0096] like Figure 1 As shown, in one embodiment of the present invention, the pole 1 is vertically fixed to the ground along the vertical direction by means of multiple support rods 3 and support plates 5, and the arm unit 300 is combined with the pole along the horizontal direction to be orthogonal to the pole.

[0097] However, the support pole 1 does not necessarily have to be vertically fixed to the ground in the vertical direction; it can be combined with the vertical wall of the building through multiple support poles 3 and support plates 5. In this case, the support pole 1 is set in the horizontal direction, and the arm unit 300 is orthogonal to the support pole 1. In fact, various embodiments with horizontal or vertical settings can also be expected.

[0098] The following, such as Figure 1 As shown, to ensure consistency in directional terminology, the description assumes that the pole 1 is vertically fixed to the ground in a horizontal position via multiple support rods 3 and support plates 5, and that the arm unit 300 extends in a horizontal direction orthogonal to the pole 1. However, it should be noted beforehand that this embodiment of the invention is not intended to limit its directionality.

[0099] The arm unit 300 acts as a medium for the connection between the arm unit 300 and the mast 1 of the antenna device A. In other words, it can also be understood that the arm unit 300 acts as a medium for the connection between the arm unit 300 and the mast 1 of the antenna clamping device 50 connected to the antenna device A.

[0100] The antenna device A, which is combined with 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 three-dimensional beamforming.

[0101] 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.

[0102] 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 along a pivot 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.

[0103] 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.

[0104] As described above, in one embodiment of the antenna clamping device 50 of the present invention, the radiation direction of the electromagnetic wave released from the front of the antenna device A combined with the mast 1 is fixed at an angle by means of a rotation unit 200 along a left-right rotation pivot, and the angle can be fixed by means of a tilting unit 100 along a vertical rotation. The angle-fixed state by means of the rotation unit 200 and the tilting unit 100 will be described in more detail below.

[0105] 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".

[0106] The following description will focus on antenna device A and begin with the adjacent structures for a more detailed explanation.

[0107] like Figures 1 to 6 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 unit 200 is mounted on the front end of the arm unit 300 to form a mounting space 331. The arm unit 300 is fixed to the support rod 1, as shown. Figure 2As shown, the antenna device A can be set up using one embodiment of the antenna clamping device 50 of the present invention.

[0108] Among them, such as Figure 4 As shown, the tilting unit 100 may include: an antenna coupling end 101, which is coupled to the antenna device A; and tilting blocks 103, which extend toward the rear of the rotating unit 200 and are coupled to one outer side or the other outer side of the rotating unit 200.

[0109] The antenna connection end 101 is a portion that is tightly attached to the back of the antenna device A, and has a bolt through hole 110a formed therein, which can be bolted together by the fastening bolt 110. Figure 4 As shown, the two bolt through holes 110a can be set at a specified distance along the vertical direction.

[0110] like Figure 4 As shown, the tilting block 103 is a part with a surface orthogonal to the mating surface of the antenna mating end 101, which is essentially a part that is mated to the left or right side of the front end of the rotating unit 200.

[0111] Multiple reinforcing ribs 107 are provided between the tilting block 103 and the antenna connection 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.

[0112] The tilting block 103 may be attached with a tilting guide 130 to guide the tilting action of the tilting unit 100 on an outer side facing the inner side of the left or right side of the front end of the rotating unit 200. The tilting guide 130 is machined into a plate shape with a slot. At the same time, the tilting block 103 may be provided with a tilting pivot pin 140, which serves as the tilting center of the tilting unit 100, on the inner side of the left or right side of the front end of the rotating unit 200.

[0113] The tilt guide 130 may include: a tilt guide groove 133, machined on a circumference centered on the tilt pivot pin 140; and a tilt guide bolt 135, which passes through the tilt guide groove 133 from the outside to fix it to the rotating unit 200.

[0114] The tilting guide portion 130 is formed in a plate shape corresponding to the shape of the guide groove mounting groove 102, which is recessed to the same depth along the inner side of the outer side of the tilting block 103, allowing the tilting guide groove 133 to pass through in the left-right direction. A fixing hole 102', which is a fastening screw 132 in the form of a flat-head screw, passes through the fastening hole 131 formed in the tilting guide portion 130 for fastening.

[0115] The inclined guide groove 133 formed in the inclined guide portion 130 is formed on the same circumference with the inclined pivot pin 140 as the center, and the inclined unit 100 can be processed in such a way that it has a circumferential surface with a maximum upward tilt rotation of 40 degrees and a downward tilt rotation of 40 degrees with respect to the horizontal.

[0116] like Figure 3 As shown, an angle label 150 may be attached to the outer side corresponding to one side of the angle guide portion 130 in the outer side of the angle block 103. The angle label 150 indicates the position of the angle guide bolt 135 moving in the angle guide groove 133 from the reference point by an angle.

[0117] The reference point related to the position of the tilt guide bolt 135 is a horizontal state where the tilting block 103 cannot tilt, represented by "0 degrees". For tilting in the upper direction and tilting in the lower direction, the tilt angle can be represented in 5-degree or 10-degree angle intervals, respectively. Therefore, after the operator installs the antenna device A on the tilting unit 100, the tilting unit 100 can be tilted and fixed in the accurate position by using the tilt angle label 150, thereby improving the reliability of the antenna device A installation operation.

[0118] The tilting pivot pin 140 is a bolt that extends from the outside to the inside of the tilting block 103. It is hinged to the outer side of the rotating unit 200 and becomes the tilting rotation center of the tilting unit 100.

[0119] The tilting units 100 described above can be combined with the tilting unit mounting ends 210 of the rotating unit 200, which are respectively arranged in pairs on the left and right sides. Therefore, unless otherwise defined, the various structures of the tilting units 100 described above and the various structures of the tilting units 100 described below are described on the premise that they are arranged in pairs on the left and right sides symmetrically.

[0120] On the other hand, a tilting brake pad 120 may be formed between the inner side of the tilting block 103 and the outer side of the rotating unit 200 (preferably, the outer side of the tilting unit mounting end 210). In the tilting brake pad 120, a fastening screw 122, which is provided in the form of a flat-head screw corresponding to the shape of the tilting pad mounting groove 104 recessed in the inner side of the tilting block 103, can be fastened to the tilting pad mounting groove 104 by means of a fastening hole 121 extending in the left-right direction and a fixing hole 108 formed in the inner side of the tilting block 103.

[0121] On the inner surface of the tilting brake pad 120, multiple brake protrusions 125 are machined to protrude inward. When the tilting unit 100 tilts, a predetermined frictional force is formed between the tilting brake pad 120 and the outer surface of the rotating unit 200, which prevents the antenna device A from being tilted arbitrarily by external forces such as the weight of the antenna device A and wind blowing around the antenna device A. As will be described later, a friction pad 212 is provided on the outer surface of the tilting unit setting end 210 of the rotating unit 200, which forms friction with the tilting brake pad 120.

[0122] A through groove 123 is formed in the tilting brake pad 120 to allow the tilting guide bolt 135 to pass through and be fastened. The through groove 123 has a shape corresponding to the tilting guide groove 133. Simultaneously, a tilting through groove 109 is machined into the tilting block 103, and the tilting through groove 109 has a shape corresponding to the tilting guide groove 133. The tilting guide bolt 135 is a bolt that is fastened to the left or right side of the front end of the rotating unit 200. It can sequentially pass through the tilting guide groove 133, the tilting through groove 109, and the through groove 123 to be fastened to the left or right side of the front end of the rotating unit 200.

[0123] In the tilting block 103 formed by the structure described above, when the antenna device A, which is combined with the front end of the tilting block 103, needs to tilt and rotate in the vertical direction, if a specified tilting external force is provided, when an external force greater than the frictional force of the tilting brake pad 120 is provided, it can be fixed after tilting in the upper or lower direction within the tilting angle range of the tilting guide groove 133.

[0124] On the other hand, such as Figure 5 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; a rotating block 220, which is inserted into the mounting space 331 of the arm unit 300; and a connecting block 230, which is used to connect the tilting unit setting end 210 and the rotating block 220.

[0125] Among them, a pair of tilting unit setting ends 210 are spaced apart from each other, and one side extends from the left end and the right end of the connecting block 230 toward the tilting unit 100 respectively. As described above, on the outer side of the tilting unit setting end 210, the tilting pivot pin 140, which serves as the tilting center of the tilting unit 100, can be connected to the tilting unit 100.

[0126] That is, as described above, the tilting blocks 103 of the tilting unit 100 are respectively disposed on the outer side of the tilting unit setting end 210 of the rotating unit 200, and a pair can be disposed in the same manner as the tilting unit setting end 210.

[0127] As described above, a rotating pin fastening hole 217 can be formed on the outer side of the tilting unit setting end 210 so that the tilting guide bolt 135 passes through the tilting block 103, the tilting guide portion 130 and the tilting brake pad 120 of the tilting unit 100 and is fixed, and the tilting pivot pin 140 passes through the tilting block 103 of the tilting unit 100 and is fastened.

[0128] Meanwhile, on the outer surface of the tilting unit mounting end 210, a friction pad 212 can be mounted in the pad mounting groove 211 via a flat-head screw 215. The friction pad 212 provides a friction surface for the braking protrusion 125 of the tilting brake pad 120 to rub against. The flat-head screw 215 can secure the friction pad 212 to the friction pad mounting hole 219 of the tilting unit mounting end 210 by passing through the friction pad mounting hole 213 formed in the friction pad 212. Therefore, the friction pad 212 can be easily replaced when it wears down due to continuous tilting action.

[0129] On the other hand, in the structure of the rotating unit 200, the rotating block 220 is a part that is inserted into the mounting space 331 formed in a hollow form at the front end of the arm unit 300, and is a part that allows the rotating unit 200 to rotate in the mounting space 331 in the left and right direction.

[0130] like Figure 5 As shown, the rotating block 220 may include: a lower block 220a, which is attached to the underside of the mounting space 331 of the arm unit 300; an upper block 220b, which is disposed above the lower block 220a at a predetermined distance and is attached to the top of the mounting space 331; and a center block 220c, which connects the lower block 220a and the upper block 220b.

[0131] On the other hand, such as Figure 5 As shown, a rotary brake pad 240 that performs the same function as the tilt brake pad 120 described above can be formed between the rotary block 220 and the arm unit 300.

[0132] More specifically, when the tilting brake pad 120 is disposed between the tilting unit setting end 210 and the tilting unit 100 to perform a tilting action, as long as a specified frictional force can be generated, the rotating brake pad 240 can generate a specified frictional force when rotating between the rotating block 220 and the arm unit 300 in the left and right direction, so as to perform the function of preventing the antenna device A from being moved in the left and right direction by an external force.

[0133] The rotary brake pad 240 can be installed in a shape corresponding to the rotary brake pad mounting groove 221 on the upper part of the upper block 220b recessed in the structure of the rotary block 220. In the rotary brake pad 240, the fastening hole 243 through which the flat-head screw 245 passes is formed in a vertical direction, and the fixing hole 225 for fastening the flat-head screw 245 is formed at the position corresponding to the rotary brake pad mounting groove 221. The rotary brake pad 240 is fixed to the rotary brake pad mounting groove 221 by the action of the flat-head screw 245 being fastened to the fastening hole 243 and the fixing hole 225 in sequence.

[0134] Multiple brake protrusions 241 are provided on the top of the rotary brake pad 240 to generate the frictional force described above between the rotary brake pad 240 and the top of the hollow mounting space 331.

[0135] On the other hand, such as Figure 5 As shown, in the structure of the rotating block 220, the upper block 220b forms an upper hinge fastening hole 222a, which forms an upper rotation pivot pin (see reference). Figure 6 The hinge point (reference numeral 335) is fastened. As a structure of the rotation guide of the arm unit 300 (described later), it can have a front-end rotation guide bolt 336a for guiding the rotation of the rotating unit 200 in the left-right direction, and front-end guide bolt fastening holes 222b and rear-end guide bolt fastening holes 222c for fastening the rear-end rotation guide bolt 336b. Simultaneously, the upper rotation pivot pin 335, the front-end rotation guide bolt 336a, and the rear-end rotation guide bolt 336b are also fastened through the rotation brake pad 240. Therefore, upper hinge through hole 242a, front-end guide bolt through hole 242b, and rear-end guide bolt through hole 242b can be formed respectively.

[0136] In the structure of the rotating block 220, the lower block 220a may be formed with a lower hinge fastening hole for mounting the installation guide unit described later (see reference). Figure 10 (See attached figure 251).

[0137] On the other hand, the antenna clamping device 50 of one embodiment of the present invention may further include a mounting guide unit for the lower block 220a disposed in the structure of the rotating block 220 (see reference). Figure 10 (See attached figure 250).

[0138] The mounting guide unit 250 is disposed in the rotating unit 200. When the rotating unit 200 is installed in the mounting space 331 of the arm unit 300, it will be elastically pressed and temporarily fixed to the lower hinge fastening hole 251, which forms a hinge point on the mounting space 331. Therefore, when the antenna device A, which serves as a designated counterweight, is combined with the front end of the tilting unit 100, the rotating unit 200 can be more easily fixed to the arm unit 300 together with the tilting unit 100. The arm unit 300 will be described first, followed by a detailed description of the mounting guide unit 250 as described above.

[0139] On the other hand, such as Figure 6 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 to form a front end portion having a mounting space 331.

[0140] The outer mounting block 310 is made of stainless steel and can form a skeleton. An outer fitting groove 343 is formed on the outer mounting block 310, which corresponds to the shape of one side of the outer peripheral surface of the rod 1. This allows the support block 340, which is made of a high-friction elastic material, to be placed between the outer mounting block 310 and the rod 1, thereby creating a gap between the outer mounting block 310 and the rod 1 that is in close contact with the ground.

[0141] At the left and right ends of the outer mounting block 310, at least one outer bolt through hole 311 is formed along the vertical direction for the fixing bolt 325 to pass through. At the position of the support block 340 corresponding to the outer bolt through hole 311, a support bolt through hole 341 is also formed. At the position of the inner mounting block 320 corresponding to the outer bolt through hole 311 and the support bolt through hole 341, inner bolt through holes 321 (not shown in the figure) can also be formed respectively.

[0142] 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, support bolt through hole 341 and 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.

[0143] The fastening nut 360 is concealed and fixed in the nut fastening part 313 formed in the space between the outer bolt through hole 311 and the support bolt through hole 341 of the outer mounting block 310, making it difficult for a third party to disassemble it at will.

[0144] The outer shaped groove 343, which is substantially in close contact with one side of the outer peripheral surface of the support block 340, can be recessed in a shape corresponding to the outer peripheral surface of the support block 1, thereby increasing the contact area for the support block 1, which has a circular horizontal cross-section. At the same time, the outer shaped 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 support block 1 by the fastening force of the fixing bolt 325 and the fastening nut 360, thereby generating stronger friction.

[0145] On the other hand, an inner groove 323 corresponding to the outer groove 343 of the support block 340 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. In addition, multiple serrated ribs can be formed in the inner groove 323 to prevent gaps from forming between the inner groove 323 and the support rod 1.

[0146] The inner mounting block 320 and the clamping arm 330 can be integrally formed. Specifically, the area of ​​the inner mounting block 320 (i.e., the front area) is relatively larger than the area occupied by the clamping arm 330. Conversely, according to an embodiment, the front end of the clamping arm 330 is formed from the retaining rod 1 at different intervals (see below). Figure 15 ).

[0147] 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, when the clamping arm 330 is relatively long, at least one reinforcing rib can be formed at the connection between the inner mounting block 320 and the clamping arm 330 (see reference). Figure 12 (See attached figure numeral "380").

[0148] Furthermore, in the antenna clamping device 50 of one embodiment of the present invention, in the case where the clamping arm 330 is relatively long, and the weight of the antenna device combined with the tilting unit 100 and the fatigue strength of the connection between the inner mounting block 320 and the clamping arm 330 based on the length of the clamping arm 330 cannot be met by simply forming at least one reinforcing rib 380 as described above, a steel reinforcement unit (refer to the reference numerals described later) may also be included to reinforce it. Figure 12 , Figure 13 and Figure 15 (See attached figure 400).

[0149] The reinforcing bar unit 400 may be equipped with a connecting wire 420. One end of the connecting wire 420 is fixed to the upper part of the arm unit 300 corresponding to the support rod 1, and the other end of the connecting wire 420 is fixed to the clamping arm 330 in the arm unit 300. The support rod 1 is provided with a mounting bracket 410 for connecting one end of the connecting wire 420 and a connecting ring 411 on one side. The front end of the clamping arm 330 in the arm unit 300 is provided with a connecting ring 412 on the other side for connecting the other end of the connecting wire 420.

[0150] As described above, the steel reinforcement unit 400 can be selectively configured by considering factors such as the length of the clamping arm 330 manufactured in a manner with different lengths, the weight of the antenna device combined with the tilting unit 100, and the fatigue strength of the connection between the inner mounting block 320 and the clamping arm 330.

[0151] An embodiment of the antenna clamping device 50 of the present invention provides the following advantages: by having clamping arms 330, which are part of the arm unit 300, have different lengths, the space constraints of multiple antenna devices (regardless of whether they are antenna devices from the same communication company) installed on a single mast 1 are eliminated, and the installation operation can be completed more easily.

[0152] On the other hand, such as Figure 6 As shown, a mounting space 331 is formed at the front end of the clamping arm 330, which allows the rotating block 220 of the rotating unit 200 to be rotatably inserted into the mounting space 331. The clamping arm 330 has a generally rectangular vertical cross section and is formed in the form of a tube with an internal empty space, which can be defined as the mounting space 331.

[0153] On the lower side of the mounting space 331, a lower hinge hole 334a, which is formed in the form of a fastening hole, can be formed through in the vertical direction, so that after the lower rotating pivot pin 337 (described later) is inserted, it is inserted and fixed into the lower hinge fastening hole 251 formed in the lower block 220a of the rotating block 220.

[0154] Furthermore, on the upper side of the mounting space 331, an upper hinge hole 334b ​​formed in the form of a fastening hole can be formed through in the vertical direction, so that after the upper rotating pivot pin 335 (described later) is inserted, it is inserted into and fixed to the upper hinge fastening hole 222a formed in the upper block 220b of the rotating block 220.

[0155] Meanwhile, at least one rotation guide 333 can be formed in the form of a slot on the upper side of the mounting space 331. The at least one rotation guide 333 is separated from the front side and the rear side formed in the upper hinge hole 334b ​​to guide the rotation of the rotating unit 200.

[0156] The rotation guide 333 may include: at least one rotation guide groove 333a, 333b, which are machined on the same circumference concentric with the upper hinge hole 334b ​​forming the hinge point as described above; and rotation guide bolts 336a, 336b, which pass through at least one rotation guide groove 333a, 333b from the outside to fix it to the rotation unit 200.

[0157] As described above, the rotation guide grooves 333a and 333b may include: a front guide groove 333a, formed on the front side with reference to the upper hinge hole 334b; and a rear guide groove 333b, formed on the rear side with reference to the upper hinge hole 334b.

[0158] Furthermore, the rotating guide bolts 336a and 336b may include: a front rotating guide bolt 336a, which passes through the front guide groove 333a and is inserted into the front guide bolt fastening hole 242b of the upper block 220b in the structure of the rotating unit 200; and a rear rotating guide bolt 336b, which passes through the rear guide groove 333b and is inserted into the rear guide bolt fastening hole 242c of the upper block 220b in the structure of the rotating unit 200.

[0159] Therefore, when an operator applies an external force to the antenna device A, which is combined with the tilting unit 100, to rotate it to one side in the left or right direction, the rotating unit 200 can rotate around the lower rotating pivot pin 337 and the lower hinge holes 334a and upper hinge holes 334b ​​that form the hinge points that engage with the upper rotating pivot pin 335, guided and restricted by the front guide groove 333a on the front side and the rear guide groove 333b on the rear side. In this case, the friction of the rotating brake pad 240 provided between the rotating block 220 and the arm unit 300 is used to prevent any rotational movement caused by external forces other than those applied by the operator.

[0160] On the other hand, a rotation angle label 350 may be attached to the front end of the clamping arm 330. The rotation angle label 350 indicates the position of the rotation guide bolts 336a and 336b moving within the rotation guide grooves 333a and 333b from a reference point by an angle. The rotation angle label 350 is provided in the same form as the tilt angle label 150 to be provided on the tilting unit 100, and a detailed description will be omitted.

[0161] Figure 7 for Figure 2 The top view is a top view showing the rotation state through the rotation unit 200. Figure 8 for Figure 2The side view is a side view showing the tilted state through the tilting unit 100. Figure 9 For along Figure 8 A sectional view taken along line AA.

[0162] Reference Figures 7 to 9 The rotation and tilting actions of an antenna clamping device 50 according to an embodiment of the present invention will be described in more detail below.

[0163] First, such as Figure 7 and Figure 9 As shown, according to the rotational movement, 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 rotating unit 200, the rotating unit 200 will be positioned within the mounting space 331 of the clamping arm 330 of the arm unit 300, at the hinge point (referring to the...). Figure 7 Using the reference numeral 335 (indicated by the upper rotating pivot pin) as a reference, the front rotating guide bolt 336a and the rear rotating guide bolt 336b rotate within the range of the front guide groove 333a and the rear guide groove 333b.

[0164] 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 shaped groove 343 and the inner shaped groove 323 formed on the arm unit 300 are respectively machined by sawing and are firmly and tightly combined with the mast 1, thereby preventing arbitrary movement during rotation.

[0165] After adjusting the rotation angle of antenna device A, a rotation brake pad 240 is installed between arm unit 300 and rotation unit 200 to prevent arbitrary rotation, thereby improving the reliability of operation.

[0166] Next, as Figure 8 and Figure 9 As shown, based on the tilting rotation 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 pivot pin 140 as a reference, causes the tilting guide bolt 135 to tilt relative to each other within the tilting guide groove 133 of the tilting guide portion 130. It should be noted that the tilting guide bolt 135 is fixed to the rotating unit 200 and does not actually move; however, it tilts relative to the tilting unit 100 through the tilting rotation action.

[0167] After adjusting the tilt angle of antenna device A, the tilt braking pad 120, which is set between the rotating unit 200 and the tilting unit 100, prevents arbitrary tilting movements, thereby improving the reliability of operation.

[0168] Figure 10 To show Figure 2 The diagram shows a cutaway perspective view and enlarged view of the installation guide unit in the structure. Figures 11a to 11c To show Figure 10 A side sectional view of the installation guide unit in operation.

[0169] like Figures 10 to 11c As shown, the antenna clamping device 50 of one embodiment of the present invention may further include an installation guide unit 250 disposed on the rotating unit 200.

[0170] like Figure 10 As shown, the installation guide unit 250 may include: a guide tube 260, which, in the rotating unit 200, has an outer end that protrudes outward by a predetermined length in a lower hinge fastening hole 251 formed such that the portion corresponding to the hinge point on the mounting space 331 is recessed upward; and an elastic body 280 that elastically supports the guide tube 260 along the outer direction of the rotating unit 200.

[0171] The mounting guide unit 250 can be disposed in the lower hinge fastening hole 251, which is formed in the lower block 220a of the rotating unit 200. Meanwhile, the elastic body 280 can be formed by a spring formed between the outer peripheral surface of the guide tube 260 and the inner peripheral surface of the lower hinge fastening hole 251.

[0172] An internal thread 252 is formed on the lower inner circumferential surface (i.e., the inner circumferential surface adjacent to the outside) of the lower hinge fastening hole 251. The mounting guide unit 250 may also include an anti-disengagement nut 270 that is threadedly engaged with the internal thread 252 to prevent the guide tube 260 from disengaging to the outside. The aforementioned internal thread 252 is formed on the inner circumferential surface of the lower hinge fastening hole 251.

[0173] As described above, the anti-disengagement nut 270 is located between the outer peripheral surface of the guide tube 260 and the inner peripheral surface of the lower hinge fastening hole 251. On the outer peripheral surface of the guide tube 260, the locking rib 261, which is locked by the anti-disengagement nut 270, extends protrudingly along the circumferential direction. On the upper side of the locking rib 261, one end of the elastic body 280 formed between the outer peripheral surface of the guide tube 260 and the inner peripheral surface of the lower hinge fastening hole 251 can be supported and fixed.

[0174] The outer end of the guide tube 260 can protrude to a length that allows it to be inserted into and locked into the hinge hole (lower hinge hole 334a) formed at the hinge point on the mounting space 331 of the arm unit 300.

[0175] like Figure 11aAs shown, in the installation guide unit 250 arranged as described above, before the tilting unit 100 and the rotating unit 200, which are combined with the antenna device A, are installed on the arm unit 300, the guide tube 260 is maintained in a state where it protrudes a predetermined length toward the outside of the lower hinge fastening hole 251.

[0176] After that, as Figure 11b As shown, in the installation guide unit 250, in order to insert the rotating block 220 of the rotating unit 200 into the installation space 331, the operator pushes the guide tube 260 into the lower hinge fastening hole 251 and inserts it into the lower surface of the work space.

[0177] Finally, if the workers continue to insert the tilting unit 100 and the rotating unit 200, which are combined with the antenna device A, into the installation space 331, the guide tube 260 will be inserted into the lower hinge hole 334a by the elastic force of the elastic body 280, thereby completing the temporary fixation. The assembly operation can be completed by the action of the lower rotating pivot pin 337 passing through the lower hinge hole 334a from the outside to fasten it to the lower hinge fastening hole 251.

[0178] As described above, in the antenna clamping device 50 of one embodiment of the present invention, the antenna device A with a large counterweight, the tilting unit 100 and the rotating unit 200 combined with the antenna device A and the arm unit 300 can be combined in a one-click manner by installing the guide unit 250, thereby greatly improving the on-site operation performance.

[0179] Figure 12 This is a modified example of the arm unit and tilting unit in the structure of an embodiment of the antenna clamping device 50 of the present invention, and is a perspective view showing an example of the installation state of the antenna device. Figure 13 for Figure 12 Decomposed 3D diagram, Figure 14a and Figure 14b To show with Figure 12 Three-dimensional and exploded three-dimensional views of the setup status of the antenna equipment of the tilting unit.

[0180] Reference Figures 12 to 14b The tilting unit 100, which is actually equipped with antenna device A, may also include an extension connection part 105, which is used to extend the connection between the antenna connection end 101 and the tilting block 103 in the left-right direction.

[0181] The extended connection portion 105 is an additional structure used to improve the bonding force with the antenna device A when the vertical length of the antenna device A is relatively large. That is, as a connection with... Figures 1 to 1 The differences of the tilting unit 100 shown in Figure 1, Figures 12 to 14bThe tilting unit 100 shown may have the additional advantage of forming fastening points at multiple locations of the antenna device A, which has a relatively long vertical length.

[0182] The extended connection portion 105 is bent in such a way that it has surfaces that are orthogonal to the antenna connection end 101 and the tilt block 103 respectively. In order to enhance the mechanical fatigue strength related to the weight of the antenna device A, a plurality of reinforcing ribs 107 may also be formed in front.

[0183] On the other hand, such as Figures 13 to 14b As shown, the antenna connection end 101 may form at least two connecting flanges 106, so that the fixing bolts 110' that have been temporarily fixed to the side of the antenna device A at multiple locations 21 are locked downward and threaded. The at least two connecting flanges 106 form U-shaped groove fastening holes 106' with upper openings.

[0184] A variation of the inclined unit 100 is shown in the example. Figure 13 In the antenna connection end 101, connecting flanges 106 are provided at the upper and lower ends on the left and the upper and lower ends on the right respectively. Connecting flanges (not marked in the attached figure) without U-groove fastening holes 106' and with conventional fastening holes 101' are formed at the middle part on the left and the middle part on the right respectively, so that they can be connected to the antenna device A at a total of 6 positions.

[0185] Among them, such as Figure 14b As shown, after the fixing bolt 110' is locked into the U-groove fastening hole 106' of the antenna coupling end 101, the fixing bolt 110' can be rotated to secure it. The fixing bolt 110' is fixed by moving the lower part of the fixing bolt 110', which is already fastened in a temporary fixed form to the threaded fastening hole 22 formed at multiple locations 21 on the side of the antenna device A, towards the antenna coupling end 101 of the tilting unit 100.

[0186] As described above, the extended connection 105 provides the advantage of being able to provide an antenna device A with a balanced and stable horizontal width or vertical length by fixing it to the threaded fastening holes 22 provided adjacent to the end side of the antenna device A.

[0187] On the other hand, such as Figure 1 and Figure 12 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 intervals of a predetermined angle; and a support plate 5 disposed at the front end of the plurality of support poles 3, and combined with ground or wall support.

[0188] 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.

[0189] Furthermore, the support plate 5 may have bolt fastening holes (not shown) to allow it to be connected to the ground or wall surface using fastening components such as bolts.

[0190] Figure 15 To show Figure 2 Three-dimensional views of various embodiments of the arm unit in the structure.

[0191] like Figure 15 As shown, in one embodiment of the antenna clamping device 50 of the present invention, the lengths of the manufactured arm units 300 can be different to make the spacing distance between the mast 1 and the antenna device A different.

[0192] In this case, if the length of the arm unit 300 is relatively longer, the weight of the antenna device A combined with the front end of the tilt unit 100 and the fatigue strength based on the length of the arm unit 300 itself can be taken into account, and the reinforcing rib 380 and the steel reinforcement unit 400 can be selectively provided in the manner described above.

[0193] More in detail, such as Figure 15 As shown, in an embodiment of the antenna clamping device 50 of the present invention, when the length of the clamping arm 330 is relatively long, if forming at least one reinforcing rib 380 alone cannot meet the weight of the antenna device A combined with the tilting unit 100 and the fatigue strength of the connection between the inner mounting block 320 and the clamping arm 330 based on the length of the clamping arm 330, a steel bar unit 400 for reinforcing it may also be included.

[0194] The reinforcing bar unit 400 may be equipped with a connecting wire 420. One end of the connecting wire 420 is fixed to the support rod 1 corresponding to the upper part of the arm unit 300, and the other end of the connecting wire 420 is fixed to the clamping arm 330 in the arm unit 300. The support rod 1 is provided with a mounting bracket 410 for connecting one end of the connecting wire 420 and a connecting ring 411 on one side. The front end of the clamping arm 330 in the arm unit 300 is provided with a connecting ring 412 on the other side for connecting the other end of the connecting wire 420.

[0195] As described above, the steel reinforcement unit 400 can be selectively configured by taking into account factors such as the length of the clamping arm 330 manufactured in a manner with different lengths, the weight of the antenna device A combined with the tilting unit 100, and the fatigue strength of the connection between the inner mounting block 320 and the clamping arm 330.

[0196] An embodiment of the antenna clamping device 50 of the present invention provides the following advantages: by having clamping arms 330, which are part of the arm unit 300, have different lengths, the space constraints of multiple antenna devices A (regardless of whether they are antenna devices from the same communication company) installed on a single mast 1 are eliminated, and the installation operation can be completed more easily.

[0197] An embodiment of the antenna clamping device of the present invention has been described in detail above with reference to the accompanying drawings. 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.
