Description

Technical Field

[0001] This application relates to base station antenna technology, and more particularly to a mounting bracket for a base station antenna. Background Technology

[0002] Base station antennas are core components of modern mobile communication networks. The mechanical tilt angles of base station antennas, such as the azimuth and vertical elevation angles, directly affect the coverage quality of the antenna network and the overall system performance.

[0003] In related technologies, base station antennas are fixed to the top of signal towers using mounting brackets. In high-altitude working environments, workers disassemble and assemble the adjusting arms of the mounting brackets to adjust the mechanical tilt angle of the base station antenna. However, in high-altitude working environments, disassembling and assembling the parts corresponding to the adjusting arms can easily cause the mounting brackets to fall apart, and the disassembled parts can easily fall, posing a safety hazard, resulting in low assembly efficiency. Summary of the Invention

[0004] This application provides a mounting bracket for a base station antenna, which improves the technical problem in related technologies where mounting brackets are inconvenient for adjusting the mechanical tilt angle of the base station antenna.

[0005] This application provides a mounting bracket for a base station antenna, comprising:

[0006] The lower bracket is used to rotatably connect the lower part of the base station antenna to an external support.

[0007] The upper bracket includes a first adjusting member connected to the upper part of the base station antenna and a second adjusting member connected to the external support member. The first adjusting member and the second adjusting member are rotatably connected so that the upper part of the base station antenna is close to or away from the external support member. The first adjusting member or the second adjusting member is provided with multiple adjusting slots.

[0008] A locking assembly includes a locking member elastically connected to the first adjusting member or the second adjusting member, the locking member being configured to switch between a locked position and an unlocked position; in the locked position, the locking member is engaged with the adjusting latch by an elastic force to restrict rotation of the first adjusting member and the second adjusting member; in the unlocked position, the locking member disengages from the adjusting latch against the elastic force to allow rotation of the first adjusting member relative to the second adjusting member.

[0009] In some embodiments, the first adjusting member includes a first connecting plate and a first adjusting arm hinged to the first connecting plate, the first connecting plate being used to connect to the base station antenna; the second adjusting member includes a second connecting plate and a second adjusting arm hinged to the second connecting plate, the second connecting plate being used to connect to the external support member, the first adjusting arm and the second adjusting arm being connected by a fastener that passes through them.

[0010] In some embodiments, the first adjusting arm is provided with a plurality of adjusting slots on the side near the fastener, and the locking member is movably disposed on the second adjusting arm; the locking assembly further includes an elastic member, one end of which is connected to the fastener and the other end of which is connected to the locking member, and the elastic member has an elastic force that drives the locking member to displace toward the adjusting slot.

[0011] In some embodiments, the locking member includes a locking plate and a first limiting member passing through the locking plate, the first limiting member being slidably connected to the second adjusting arm; the first limiting member is connected to the elastic member, and the first limiting member is engaged in the adjusting position by the elastic force of the elastic member.

[0012] In some embodiments, a second limiting member is provided through the locking plate, and the second limiting member is slidably connected to the second adjusting arm; wherein the sliding paths of the second limiting member and the first limiting member on the second adjusting arm are not parallel, so that the locking plate is driven by external pressure to disengage the first limiting member from the adjusting position.

[0013] In some embodiments, the locking plate includes a plate body and a pressing portion bent relative to the plate body, the pressing portion being located on the side of the plate body away from the second adjusting arm; the two ends of the plate body are bent to form mounting portions, and the first limiting member and the second limiting member pass through the mounting portions and are connected to the second adjusting arm.

[0014] In some embodiments, the fastener is a square neck bolt, and the second adjusting arm is provided with a square hole corresponding to the square neck of the square neck bolt.

[0015] In some embodiments, the fastener is fitted with an isolation tube, and the two ends of the isolation tube abut against the second adjusting arm.

[0016] In some embodiments, the plurality of adjustment slots are evenly distributed circumferentially along the rotation axis of the first adjustment member or the second adjustment member.

[0017] In some embodiments, a clamping member is connected to the second connecting plate, and the clamping member and the second connecting plate together clamp the external support member.

[0018] The base station antenna mounting bracket provided in this application embodiment has a locking member that is elastically connected to a first adjusting member or a second adjusting member. The locking member is configured to switch between a locked position and an unlocked position. Thus, the elastically connected locking member is always connected to the upper bracket in both the locked and unlocked positions. The mechanical tilt angle of the base station antenna can be adjusted without disassembling the mounting bracket, reducing the safety hazards caused by disassembling parts and avoiding wear and tear on the bracket connection parts caused by repeated disassembly and assembly of the mounting bracket.

[0019] Furthermore, in the locked position, the locking element is engaged with the adjustment slot by an elastic force to restrict the rotation of the first and second adjustment elements; in the unlocked position, the locking element overcomes the elastic force and disengages from the adjustment slot to allow the first adjustment element to rotate relative to the second adjustment element. Thus, the operator can manually adjust the position of the locking element to change the engagement state of the locking element in different adjustment slots, enabling single-person operation without additional tools or personnel, effectively shortening the time for debugging the mechanical tilt angle of the base station antenna and improving debugging efficiency.

[0037] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application.

[0039] As mentioned in the background technology section, base station antennas are an important component of modern communication networks. With the continuous development of communication technology, the usage of base station antennas is increasing year by year. Base station antennas are installed on the top of signal towers using mounting brackets. Currently, the installation of base station antennas is mostly done manually at height. Base station antennas are heavy, and the antenna bracket installation method is relatively complex. Construction workers have low installation efficiency when working at heights, and the operation is inconvenient and adjusting the mechanical tilt angle is difficult, which poses certain dangers.

[0040] In related technologies, base station antenna mounting brackets often use dials or long strip-shaped slots to control the mechanical tilt angle of the base station antenna. However, with dial-shaped mounting brackets, construction workers standing tens of meters above the dial, more than one meter away, find it difficult to clearly identify the dense scale, making operation inconvenient and requiring repeated adjustments to approach the target angle, which seriously affects the efficiency of base station deployment. When using mounting brackets with long strip-shaped slots to adjust the mechanical tilt angle, the long strip-shaped slots need to be completely disassembled, and the disassembled parts pose a risk of falling, creating a safety hazard of falling from a height.

[0041] Based on this, one or more embodiments of this application provide a mounting bracket for a base station antenna, which is elastically connected to a locking member of a first adjusting member or a second adjusting member. The locking member is configured to switch between a locked position and an unlocked position. Thus, the elastically connected locking member is always connected to the upper bracket in both the locked and unlocked positions, allowing the mechanical tilt angle of the base station antenna to be adjusted without disassembling the mounting bracket. This reduces the safety hazards caused by disassembling parts and avoids wear and tear on the bracket connection parts caused by repeated disassembly and assembly of the mounting bracket.

[0042] The mounting bracket for the base station antenna according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown in the embodiment of this application, the mounting bracket for the base station antenna includes a lower bracket 100, an upper bracket 200, and a locking assembly 300.

[0044] The lower bracket 100 is used to rotatably connect the base station antenna 500 and the external support 400; the upper bracket 200 includes a first adjusting member 210 connected to the base station antenna 500 and a second adjusting member 220 connected to the external support 400. The first adjusting member 210 and the second adjusting member 220 are rotatably connected so that the base station antenna 500 can rotate relative to the external support 400. The first adjusting member 210 or the second adjusting member 220 is provided with a plurality of adjusting slots 213; the locking assembly 300 includes a locking member 310 elastically connected to the first adjusting member 210 or the second adjusting member 220. The locking member 310 is configured to switch between a locked position and an unlocked position.

[0045] In the locked position, the locking member 310 is engaged with the adjusting slot 213 by the elastic force to restrict the rotation of the first adjusting member 210 and the second adjusting member 220; in the unlocked position, the locking member 310 overcomes the elastic force and disengages from the adjusting slot 213 to allow the first adjusting member 210 to rotate relative to the second adjusting member 220.

[0046] As can be seen from the above description, the mounting bracket for the base station antenna provided in this application embodiment, by setting a locking component 300, the locking part 310 of the locking component 300 remains connected to the upper bracket 200 in both the locked and unlocked positions, so that the mechanical tilt angle of the base station antenna 500 can be adjusted without disassembling parts, making the operation more convenient and simple, and effectively avoiding the problem of complicated debugging caused by disassembling parts during the debugging process.

[0047] Furthermore, in the locked position, the locking member 310 is engaged with the adjustment slot 213 by the elastic force to restrict the rotation of the first adjustment member 210 and the second adjustment member 220; in the unlocked position, the locking member 310 overcomes the elastic force and disengages from the adjustment slot 213 to allow the first adjustment member 210 to rotate relative to the second adjustment member 220. Thus, the operator can manually adjust the position of the locking member 310 to change the engagement state of the locking member 310 in different adjustment slots 213, enabling single-person operation without additional tools or personnel, effectively shortening the time for debugging the 500° mechanical tilt angle of the base station antenna and improving debugging efficiency.

[0048] In this embodiment, the external support 400 is a support structure for supporting and installing the base station antenna 500. For example, the external support 400 can be a communication tower mast-like support structure, such as a communication pole, guyed tower, four-corner steel tower, or triangular steel pipe tower, etc. Alternatively, the external support 400 can be a building attachment-like support structure, such as a building exterior wall, concrete structural column, elevator shaft exterior wall, etc. This embodiment does not impose an absolute limitation on this.

[0049] like Figure 1 and Figure 3 As shown, in some embodiments, the first adjusting member 210 includes a first connecting plate 211 and a first adjusting arm 212 hinged to the first connecting plate 211. The first connecting plate 211 is used to connect to the base station antenna 500. The second adjusting member 220 includes a second connecting plate 221 and a second adjusting arm 222 hinged to the second connecting plate 221. The second connecting plate 221 is used to connect to the external support member 400. The first adjusting arm 212 and the second adjusting arm 222 are connected by a fastener 230 that passes through them.

[0050] Square neck bolts can be used to connect the first connecting plate 211 and the first adjusting arm 212, and the second connecting plate 221 and the second adjusting arm 222. During the coarse adjustment, the square neck bolts are loosened to allow the first adjusting arm 212 to rotate relative to the first connecting plate 211 and the second adjusting arm 222 to rotate relative to the second connecting plate 221. After the coarse adjustment is completed, the square neck bolts are tightened.

[0051] Specifically, the first connecting plate 211 is fixed to the back mounting surface of the base station antenna 500 by bolt fastening or welding. The first connecting plate 211 and the first adjusting arm 212 are rotatably connected by a square neck bolt that passes through both of them. The axis of the square neck bolt is parallel to the mounting surface of the base station antenna 500, so that the first adjusting arm 212 can rotate relative to the base station antenna 500 in the vertical plane.

[0052] Here, the first adjusting arm 212 is a long strip plate-like structure, and a circular through hole is provided at the hinge end away from the first connecting plate 211. This circular through hole is used to form a rotatable connection with the second adjusting arm 222.

[0053] Similarly, the second adjusting member 220 includes a second connecting plate 221 and a second adjusting arm 222 hinged to the second connecting plate 221. The second connecting plate 221 is fixedly connected to the external support member 400 by bolts or clamps 223. The second connecting plate 221 and the second adjusting arm 222 are also rotatably connected by square neck bolts. The axis of the square neck bolts is parallel to the surface of the external support member 400, allowing the second adjusting arm 222 to rotate relative to the external support member 400 in a vertical plane. The second adjusting arm 222 has a circular through hole at one end corresponding to the first adjusting arm 212. Fasteners 230 pass through the circular through holes of both the first adjusting arm 212 and the second adjusting arm 222, thus forming a rotatable connection between the first adjusting arm 212 and the second adjusting arm 222.

[0054] It should be noted that in some embodiments, such as Figure 1 As shown, when the external support 400 is a communication tower mast, in order to facilitate the installation of the second connecting plate 221 on the communication tower mast, the second connecting plate 221 is connected to a clamp 223. The clamp 223 and the second connecting plate 221 together clamp the communication tower mast, thereby forming a connection between the second adjusting member 220 and the external support 400.

[0055] Both the first connecting plate 211 and the second connecting plate 221 are provided with square holes for corresponding square neck bolts. Specifically, taking the first connecting plate 211 as an example, the two sides of the first connecting plate 211 are bent to form folded plates 2111. One folded plate 2111 is provided with a square hole, and the other folded plate 2111 is provided with a circular hole. The square neck of the square neck bolt is correspondingly engaged in the square hole, and the cylindrical rod-shaped part passes through the circular hole. This prevents the first connecting plate 211 from rotating endlessly relative to the first adjusting angle arm 212, which would affect the adjustment effect.

[0056] Of course, during the actual debugging process, the coarse adjustment of the mechanical tilt angle of the base station antenna 500 can be achieved by loosening the square neck bolt, allowing the cylindrical rod-shaped part of the square neck bolt to enter the square hole. At this time, the first connecting plate 211 can rotate freely relative to the first adjusting arm 212. After the coarse adjustment is completed, the square neck is inserted into the square hole, and the square neck bolt is tightened to fix the position of the first connecting plate 211 and the first adjusting arm 212.

[0057] The connection method and debugging process of the second connecting plate 221 and the second adjusting arm 222 can refer to the above-mentioned settings of the first connecting plate 211 and the first adjusting arm 212, which will not be repeated in this embodiment.

[0058] By setting square neck bolts on the first connecting plate 211 and the second connecting plate 221, the angle range of the first adjusting member 210 and the second adjusting member 220 can be coarsely adjusted without disassembling the square neck bolts. Compared with the traditional adjustment method that requires complete removal of bolts, this greatly reduces the steps of disassembling and assembling parts during high-altitude operations, which helps to reduce the risk of parts falling and improves the convenience and efficiency of coarse adjustment operations.

[0059] The first adjusting arm 212 and the second adjusting arm 222 are rotatably connected by a fastener 230 that passes through them. The fastener 230 is also a square neck bolt. The screw part of the square neck bolt passes through the circular through hole of the first adjusting arm 212 and the second adjusting arm 222 in sequence, and the nut is screwed onto the end of the screw.

[0060] Here, fastener 230 is kept in a pre-tightened state during assembly, not fully tightened, so that the first adjusting arm 212 and the second adjusting arm 222 remain in contact under the action of axial pre-tightening force, while being able to rotate relative to each other around the screw axis, thereby realizing the mechanical tilt angle adjustment of the base station antenna 500 relative to the external support 400. The pre-tightening state of fastener 230 is achieved by controlling the tightening torque of the nut. The specific torque value is determined according to the support load requirements and rotation flexibility requirements. Under the premise of ensuring the stability of the support structure, operators are allowed to manually adjust the antenna angle by moving it.

[0061] By setting up a first adjusting angle arm 212 and a second adjusting angle arm 222, the double-angle arm hinge structure of the first connecting plate 211 and the first adjusting angle arm 212, the second connecting plate 221 and the second adjusting angle arm 222 forms a four-bar linkage mechanism. The antenna tilt angle is adjusted by the relative rotation of the first adjusting angle arm 212 and the second adjusting angle arm 222. Compared with the traditional single-arm support structure, it has higher structural rigidity and wind resistance, which is conducive to dispersing stress concentration and improving the overall stability and service life of the mounting bracket.

[0062] like Figure 3 and Figure 4As shown, in some embodiments, the first adjusting arm 212 is provided with a plurality of adjusting slots 213 on the side near the fastener 230, and the locking member 310 is movably disposed on the second adjusting arm 222; the locking assembly 300 also includes an elastic member 320, one end of which is connected to the fastener 230 and the other end is connected to the locking member 310, and the elastic member 320 has an elastic force that drives the locking member 310 to move toward the adjusting slots 213.

[0063] In the above embodiment, multiple adjustment slots 213 are disposed on the edge side of the first adjustment arm 212 near the fastener 230, and the multiple adjustment slots 213 are evenly distributed circumferentially along the rotation axis of the first adjustment arm 212.

[0064] For example, the adjusting slot 213 is a slot-type slot. The side edge of the first adjusting arm 212 is machined with continuous or discontinuous toothed grooves. The toothed groove contour of the adjusting slot 213 can be rectangular, trapezoidal, arc-shaped, or V-shaped. The toothed groove contour matches the end shape of the locking member 310 to form a snap-fit. Here, the opening side of the adjusting slot 213 can be provided with a guide slope or rounded corner to facilitate the smooth sliding of the locking member 310 into the adjusting slot 213 under elastic force, and to prevent the locking member 310 from getting stuck with the adjusting slot 213.

[0065] In addition, the first adjustment arm 212 has different adjustment positions 213, and corresponding numerical labels can be set to set multiple adjustment positions 213 in a gradient so that operators can judge the adjustment accuracy of the mechanical tilt angle.

[0066] Here, adjustment slots 213 are provided on both opposite sides of the first adjusting arm 212. That is, both ends of the locking member 310 simultaneously engage with the adjustment slots 213 on both opposite sides of the first adjusting arm 212. The symmetrical engagement structure on both sides ensures that the force exerted by the locking member 310 on the first adjusting arm 212 is symmetrically distributed, avoiding uneven force and deflection that might occur if the locking member 310 engages with the first adjusting arm 212 on only one side. In the locked state, the relative rotation between the first adjusting arm 212 and the second adjusting arm 222 is restricted by both sides simultaneously, effectively improving the reliability and structural stability of the locking. In addition, the symmetrical engagement structure on both sides can also distribute the contact stress between the adjustment slots 213 and the locking member 310 to the contact surfaces corresponding to the two adjustment slots 213, reducing unilateral wear of the first adjusting arm 212 and helping to extend the service life of the locking assembly 300.

[0067] like Figures 3 to 5As shown, in some embodiments, the locking member 310 includes a locking plate 311 and a first limiting member 312 passing through the locking plate 311. The first limiting member 312 is slidably connected to the second adjusting arm 222. The first limiting member 312 is connected to the elastic member 320, and the first limiting member 312 is engaged into the adjusting position 213 by the elastic force of the elastic member 320.

[0068] Here, the first limiting member 312 is a rod-shaped structure. Both ends of the first limiting member 312 pass through the two sides of the locking plate 311 and protrude from the side end of the second adjusting arm 222, and are fixed to the second adjusting arm 222 by a threaded nut. Here, the second adjusting arm 222 is provided with a first guide groove 224. The first limiting member 312 slides in the first guide groove 224, thereby causing the locking plate 311 to slide and displace along the length direction of the second adjusting arm 222.

[0069] In the above embodiment, the elastic element 320 can be a spring. One end of the spring is connected to the fastener 230, and the other end is connected to the first limiting element 312. Thus, in the initial state of the elastic element 320, the first limiting element 312 is subjected to the elastic contraction force of the elastic element 320, which drives the first limiting element 312 to move toward the adjusting position 213.

[0070] As an alternative implementation, two elastic elements 320 are arranged side by side, and the two elastic elements 320 synchronously drive the first limiting member 312 into the adjusting slot 213. Here, the end of the elastic element 320 is sleeved on the fastener 230, so that the elastic element 320 can rotate relative to the fastener 230. This arrangement can prevent the elastic element 320 from being pulled away from the fastener 230 during the displacement of the first limiting member 312, thereby helping to maintain the stable connection of the elastic element 320.

[0071] Furthermore, in this embodiment of the application, a second limiting member 313 is provided on the locking plate 311, and the second limiting member 313 is slidably connected to the second adjusting arm 222; wherein, the sliding paths of the second limiting member 313 and the first limiting member 312 on the second adjusting arm 222 are not parallel, so that the locking plate 311 is driven by external pressure to disengage the first limiting member 312 from the adjusting position 213.

[0072] The first limiting member 312 and the second limiting member 313 are spaced apart on the locking plate 311. The second limiting member 313 can be installed in the same way as the first limiting member 312 on the locking plate 311. That is, the second limiting member 313 adopts a rod-shaped structure, with both ends of the second limiting member 313 passing through the two sides of the locking plate 311 and extending out of the side end of the second adjusting arm 222. It is fixed to the second adjusting arm 222 by a threaded nut. Here, the second adjusting arm 222 is provided with a second guide groove 225 corresponding to the second limiting member 313. The second limiting member 313 slides in the second guide groove 225, thereby causing the locking plate 311 to slide and displace along the length direction of the second adjusting arm 222.

[0073] The sliding paths of the second limiting member 313 and the first limiting member 312 on the second adjusting arm 222 are not parallel. That is, the second guide groove 225 and the first guide groove 224 corresponding to the first limiting member 312 are not parallel. Their extension directions intersect to form an angle, which is in the range of 30°-60°. The specific angle is determined according to the need for effortless operation and the layout of the structural space.

[0074] The non-parallel arrangement of the first guide groove 224 and the second guide groove 225 enables the locking plate 311, the first limiting member 312 and the second limiting member 313 to form a movable triangular linkage mechanism. When the operator applies external pressure to the locking plate 311, the pressure direction is perpendicular to the surface of the locking plate 311 and points towards the second adjusting arm 222. Since the first guide groove 224 and the second guide groove 225 are not parallel, the sliding action of the second limiting member 313 in the second guide groove 225 forces the locking plate 311 to make lateral displacement, so that the locking plate 311 slides towards the adjusting position 213 during the downward movement, and the first limiting member 312 extends into the adjusting position 213 along with the lateral sliding of the locking plate 311.

[0075] Compared to directly pulling the locking plate 311 to overcome the elastic force of the elastic element 320 and disengage the first limiting element 312 from the adjusting position 213, the cooperation of the second limiting element 313 and the second guide groove 225 can convert the pressing force into the lateral displacement of the locking plate 311. In high-altitude working environments, operators can operate the locking plate 311 more easily and effortlessly, making the operation simple and convenient.

[0076] In the above embodiments, for example, the locking plate 311 includes a plate body 3111 and a pressing portion 3112 bent relative to the plate body 3111. The pressing portion 3112 is located on the side of the plate body 3111 away from the second adjusting arm 222. The two ends of the plate body 3111 are bent to form mounting portions 3113. The first limiting member 312 and the second limiting member 313 pass through the mounting portion 3113 and are connected to the second adjusting arm 222.

[0077] The locking plate 311 is a metal part formed by integral stamping or sheet metal bending. The plate body 3111 of the locking plate 311 is a flat plate structure, which is set parallel to the surface of the second adjustment arm 222. There is a certain gap between the plate body 3111 and the second adjustment arm 222 to facilitate the sliding action of the locking member 310. The pressing part 3112 is formed by bending and extending from one side edge of the plate body 3111 in a direction away from the second adjustment arm 222. The surface of the pressing part 3112 can be processed with anti-slip texture so that the operator can manually press and apply force.

[0078] Both ends of the plate body 3111 are bent to form a mounting part 3113. The mounting part 3113 is bent toward the direction of the second adjusting arm 222 and is perpendicular to the plate body 3111 by 90°. Each mounting part 3113 has an opening through which the first limiting member 312 and the second limiting member 313 pass. When the operator applies external pressure to the pressing part 3112, the pressure is transmitted to the mounting part 3113 through the plate body 3111. Since the first limiting member 312 and the second limiting member 313 are slidably connected to the second adjusting arm 222, the mounting part 3113 drives the first limiting member 312 and the second limiting member 313 to slide, causing the plate body 3111 to move in the lateral direction of the second adjusting arm 222, thus disengaging the first limiting member 312 from the adjusting slot 213.

[0079] An independent pressing part 3112 is provided on the plate body 3111, which can separate the operating part and the action execution part of the locking plate 311, providing more operating space for operators and making it easier to apply force to the locking plate 311.

[0080] In some embodiments, the fastener 230 is a square neck bolt, and the second adjusting arm 222 is provided with a square hole corresponding to the square neck of the square neck bolt.

[0081] When the square neck bolt is inserted into the second adjusting arm 222, the square neck of the bolt is engaged in the square hole. Because the square hole provides circumferential constraint to the square neck, the square neck bolt cannot rotate around its own axis. The operator only needs to use a single wrench to tighten or loosen the nut, without the need for other operators to assist in fixing the bolt, nor is it necessary to use another wrench to fix the nut part of the square neck bolt on the opposite side, which simplifies the operation difficulty of high-altitude work.

[0082] Here, the fastener 230 is fitted with an isolation tube 231, and the two ends of the isolation tube 231 abut against the second adjusting arm 222 respectively.

[0083] The aforementioned isolation tube 231 is made of high-strength metal or engineering plastic. The length of the isolation tube 231 is approximately equal to the width of both ends of the second adjusting arm 222, and the inner diameter is slightly larger than the outer diameter of the square neck bolt. The two ends of the isolation tube 231 abut against the opposite side surfaces of the second adjusting arm 222.

[0084] During assembly, the isolation tube 231 is located outside the screw portion of the fastener 230. When the nut of the fastener 230 is tightened, the tightening force is transmitted to both ends of the isolation tube 231 through the nut and bolt head, rather than acting directly on the plate surface of the second adjusting arm 222. The isolation tube 231 bears the compressive load and evenly distributes the load onto the contact area of ​​the second adjusting arm 222, avoiding local deformation or crushing of the second adjusting arm 222 due to concentrated tightening pressure. At the same time, the isolation tube 231 provides rigid support for the fastener 230, preventing wear on the hole wall of the second adjusting arm 222 due to friction and compression during repeated adjustments, which helps the second adjusting arm 222 maintain hole position accuracy.

[0085] Furthermore, in the above embodiment, the adjustment slot 213 is disposed on the first adjustment arm 212 and the locking member 310 is disposed on the second adjustment arm 222. As an alternative implementation, the positions of the adjustment slot 213 and the locking member 310 can be interchanged, that is, the adjustment slot 213 is disposed on the second adjustment arm 222 and the locking member 310 is disposed on the first adjustment arm 212.

[0086] In this embodiment, the lower bracket 100 includes a clamp 110 and a connector 120 connected to the clamp 110. The clamp 110 is connected to the external support 400, and the connector 120 is connected to the lower part of the base station antenna 500. The connector 120 and the clamp 110 are connected by a square neck bolt that passes through both. The threaded portion of the square neck bolt between the connector 120 and the clamp 110 is also fitted with an isolation tube 231, which will not be described in detail in this embodiment.

[0087] Therefore, the lower bracket 100 itself only has the function of driving the base station antenna 500 to rotate relative to the external support 400 or fixing it to the external support 400, and has no function of adjusting the mechanical tilt angle of the base station antenna 500.

[0088] An exemplary installation process for the base station antenna mounting bracket of this application embodiment is as follows:

[0089] In the factory pre-assembled state, the fastener 230 of the mounting bracket is in a loose state, and the second connecting plate 221 and the clamp 223 are connected but not fully tightened.

[0090] First, install the lower bracket 100, then install and fix the clamp 110 of the lower bracket 100 to the lower part of the external support 400. Install and fix the clamp 223 of the upper bracket 200 to the upper part of the external support 400. Connect the lower part of the base station antenna 500 to the lower bracket 100, and connect and fix the upper part of the base station antenna 500 to the first connecting plate 211 of the mounting bracket. All the square neck bolts on the mounting bracket are in the pre-installed loosened state.

[0091] The mechanical tilt angle of the base station antenna 500 is roughly adjusted, the angles of the first connecting plate 211 and the first adjusting arm 212 are adjusted, and the angles of the second connecting plate 221 and the second adjusting arm 222 are adjusted. After determining the approximate angle, the square neck bolts of the first connecting plate 211 and the first adjusting arm 212 are tightened and fixed, and the square neck bolts of the second connecting plate 221 and the second adjusting arm 222 are tightened and fixed.

[0092] Next, the mechanical tilt angle of the base station antenna 500 is finely adjusted. The operator presses the pressing part 3112 of the locking plate 311, the elastic element 320 is tensioned, the first limiting element 312 slides in the first guide groove 224, and the second limiting element 313 slides in the second guide groove 225, so that the first limiting element 312 overcomes the elastic force of the elastic element 320 and disengages from the adjusting slot 213. At this time, the first adjusting arm 212 and the second adjusting arm 222 can rotate normally to adjust the mechanical tilt angle of the base station antenna 500.

[0093] After the angle adjustment is completed, release the pressing part 3112. The locking plate 311 slides in the opposite direction under the contraction force of the elastic member 320, so that the first limiting member 312 is re-engaged into the corresponding adjustment position 213. Tighten the square neck bolt corresponding to the fastener 230 to complete the installation of the base station antenna 500 and the mechanical tilt adjustment.

[0094] In subsequent maintenance, when it is necessary to change the mechanical tilt angle of the base station antenna 500, loosen the square neck bolt corresponding to the fastener 230, and repeat the pressing operation of the pressing part 3112 to adjust the mechanical tilt angle of the base station antenna 500. After adjustment, tighten the square neck bolt of the fastener 230. The entire process can be completed by a single person without the assistance of multiple people, and does not involve disassembling parts to adjust the mechanical tilt angle, making the operation more convenient and faster.
