Description

Technical Field

[0001] The present invention relates to the technical field of base station antennas, and particularly to a dual-polarized base station antenna. Background Art

[0002] Mobile communication is one of the important systems for modern information transmission and communication. With the continuous development of cities, the coverage of mobile communication networks is constantly expanding and improving. Generally, a large number of base station antennas are built. According to the actual situations such as network coverage requirements, traffic distribution, anti-interference requirements, and network service quality, base station antennas are reasonably selected. Since the selection of antenna types is closely related to terrain, ground objects, and traffic distribution, the antenna usage environment can be roughly divided into five types: urban areas, dense urban areas, suburbs, rural areas, transportation arteries, etc. Base station antennas are usually erected at high altitudes through a support rod and tilted at a certain downward tilt angle. The change of the tilt angle directly affects the coverage effect of the base station. The dual-polarized base station antenna is a new antenna technology that combines two antennas with mutually orthogonal polarization directions of +45° and -45° and operates in a transceiver duplex mode at the same time, having the outstanding advantage of saving the number of antennas for a single directional base station. In real life, generally, the way of increasing the base station antennas is adopted to meet the requirements such as network coverage requirements, traffic distribution, anti-interference, and network service quality; therefore, using the dual-polarized base station antenna in base station antennas can improve the usage effect of base station antennas.

[0003] Chinese Patent with Publication No. CN207542384U discloses a dual-polarized base station antenna, including an antenna fixing frame, an antenna placement box, an antenna outlet, and a dual-polarized oscillator. Above the antenna fixing frame, a chuck clamping screw is installed. Above the chuck clamping screw, a serrated chuck is installed. Above the antenna placement box, a middle fixer is provided. Above the middle fixer, a placement box rotating head is installed. Above the placement box rotating head, a placement box opening cover is installed. Above the placement box opening cover, the antenna outlet is connected. Below the antenna outlet, an angle adjustment shaft is installed. Inside the antenna placement box, an antenna support foot is installed. Above the antenna support foot, a base station antenna is connected. Above the base station antenna, the dual-polarized oscillator is installed. Below the dual-polarized oscillator, a metal reflector is installed. The beneficial effects are as follows: The dual-polarized base station antenna is small in volume, compact in structure, and convenient to install, greatly reducing the installation cost.

[0004] Due to the relatively large overall size of the existing dual-polarized base station antennas, their installation is rather inconvenient. Moreover, the tilt angle of the base station antenna affects the signal radiation range. During use, it is necessary to adjust the tilt angle of the antenna to solve waveform distortion and improve the effectiveness of the base station antenna radiation. However, when adjusting the tilt angle of the antenna, it is necessary to loosen the bolts on the installed base station antenna and then adjust the overall angle, which is rather inconvenient to use. For this reason, we provide a dual-polarized base station antenna to solve the above problems. Summary of the Invention

Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] As Figures 1 - 10 shown, the present invention provides a technical solution: a dual-polarized base station antenna, including a support vertical rod 1, a mounting frame 2 and an antenna body 3. The top of the support vertical rod 1 is fixedly connected with a fixed collar 4. The top of the fixed collar 4 is fixedly connected with a connecting seat 5. The inner side of the connecting seat 5 is movably connected with a fixing mechanism 6. The rear end of the mounting frame 2 is fixedly connected with a fixing plate 7, and the fixing mechanism 6 is movably connected to the outside of the fixing plate 7. The front end of the mounting frame 2 is fixedly connected with a support plate 8, and the inner side of the support plate 8 is movably connected with an adjusting mechanism 10. The antenna body 3 is movably connected to the front end of the adjusting mechanism 10, and a coaxial connector 9 is arranged below the antenna body 3. The bottom end of the adjusting mechanism 10 is fixedly connected with a locking mechanism 11, and the locking mechanism 11 is movably connected to the inside of the support plate 8.

[0046] By inserting the mounting bracket 2 into the inner side of the connecting base 5, the fixing plate 7 is located on the inner side of the connecting base 5. Subsequently, the fixing rods 601 are rotated respectively, so that the first clamping plate 603 and the second clamping plate 604 move inward in the connecting base 5, making the first clamping plate 603 and the second clamping plate 604 approach each other until the first clamping plate 603 is in contact with the second clamping plate 604. At this time, the front ends of the first clamping plate 603 and the second clamping plate 604 are respectively inserted into the fixing slots 14 on both sides of the fixing plate 7, fixing the mounting bracket 2 to the connecting base 5, thereby fixing the antenna body 3 on the upper side of the support vertical pole 1. When disassembling the base station antenna, just rotate the fixing rod 601 outward to make the first clamping plate 603 and the second clamping plate 604 move away from the fixing plate 7, and then the base station antenna can be disassembled, which is convenient for installing and quickly disassembling the base station antenna. When it is necessary to adjust the tilt angle of the base station antenna, by simultaneously pushing the connecting side plate 1104 outward, the connecting spring 1105 is compressed, making the locking part 1103 move away from the fixing slots 20 on both sides of the adjusting strip 1102. Subsequently, pull down the fixing long plate 1101, so that the fixing long plate 1101 drives the adjusting strip 1102 to move downward, and at the same time drives the backing plate 1001 to move downward, making the connecting rod 1002 drive the linkage plate 1003 to rotate downward. At the same time, the linkage rod 1004 slides backward in the moving slots 15 on both sides of the support plate 8, making the lower side of the mounting guide plate 1005 rotate inward around the support plate 8, and at the same time driving the antenna body 3 to rotate inward. On the contrary, pushing up the fixing long plate 1101 makes the backing plate 1001 move upward, and at the same time drives the linkage plate 1003 to rotate upward, so that the lower side of the mounting guide plate 1005 can rotate outward around the support plate 8, thereby adjusting the tilt angle of the antenna body 3. When the appropriate angle is adjusted, release the connecting side plate 1104, and under the action of the connecting spring 1105, the connecting side plate 1104 moves inward simultaneously, making the locking part 1103 insert into the fixing slots 20 on both sides of the adjusting strip 1102 to fix and limit the adjusting strip 1102, thereby fixing the angle of the antenna body 3, which is convenient for adjusting the tilt angle of the antenna body 3. Without disassembling the installed base station antenna, the overall angle can be adjusted, which is convenient for use.

[0047] Such as Figure 1 , Figure 3 and Figure 8As shown in the figure, the fixing mechanism 6 includes a fixing rod 601, a sliding block 602, a first clamping plate 603 and a second clamping plate 604. There is a set of the first clamping plate 603 and the second clamping plate 604 respectively, and the first clamping plate 603 and the second clamping plate 604 are symmetrically distributed. The rear ends of the first clamping plate 603 and the second clamping plate 604 are fixedly connected with the sliding block 602, and the first clamping plate 603 and the second clamping plate 604 are in contact with each other.

Both ends of the fixing rod 601 are respectively movably connected inside the connecting seat 5, and the limiting guide posts 12 are located inside the connecting seat 5. The first clamping plate 603 and the second clamping plate 604 are located inside the connecting seat 5; a set of sliding grooves 13 are provided inside the connecting seat 5, and the first clamping plate 603 and the second clamping plate 604 are respectively movably connected inside the sliding grooves 13 through the sliding blocks 602. The fixing plate 7 is located on the opposite side of the first clamping plate 603 and the second clamping plate 604, and the first clamping plate 603 and the second clamping plate 604 are respectively movably connected to the outer side of the fixing plate 7. A set of corresponding fixing card slots 14 are respectively provided on both sides of the fixing plate 7, and the front ends of the first clamping plate 603 and the second clamping plate 604 are respectively movably connected to the inside of the fixing card slots 14.

[0048] By inserting the mounting bracket 2 into the inside of the connecting seat 5, the fixing plate 7 is located inside the connecting seat 5. Then, the fixing rod 601 is rotated respectively to make the first clamping plate 603 and the second clamping plate 604 move inward in the connecting seat 5, so that the first clamping plate 603 and the second clamping plate 604 approach each other until the first clamping plate 603 is in contact with the second clamping plate 604. At this time, the front ends of the first clamping plate 603 and the second clamping plate 604 are respectively inserted into the fixing card slots 14 on both sides of the fixing plate 7, and the mounting bracket 2 is fixed to the connecting seat 5, thereby fixing the antenna body 3 on the upper side of the support vertical rod 1. When disassembling, only need to rotate the fixing rod 601 outward to make the first clamping plate 603 and the second clamping plate 604 away from the fixing plate 7, so that the first clamping plate 603 and the second clamping plate 604 are away from the fixing card slots 14, then the base station antenna can be disassembled, which is convenient for the installation and quick disassembly of the base station antenna, and is convenient and fast.

[0049] As Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the adjusting mechanism 10 includes a backing plate 1001, a connecting rod 1002, a linkage plate 1003, a linkage rod 1004 and a mounting guide plate 1005.

A second moving groove 17 is formed on the inner side of the mounting guide plate 1005, and the front end of the linkage plate 1003 is movably connected to the inner side of the second moving groove 17. The lower side of the mounting guide plate 1005 is movably connected to the inner side of the support plate 8 through a rotating shaft, and the rear end of the antenna body 3 is fixedly connected to the front side of the mounting guide plate 1005 through a bolt.

[0050] By pulling down the backing plate 1001, the connecting rod 1002 drives the linkage plate 1003 to rotate downward. At the same time, the linkage rod 1004 slides backward in the moving grooves 15 on both sides of the support plate 8, so that the lower side of the mounting guide plate 1005 rotates inward around the support plate 8, and at the same time drives the antenna body 3 to rotate inward. On the contrary, by pushing up the backing plate 1001, the linkage plate 1003 rotates upward, so that the lower side of the mounting guide plate 1005 rotates outward around the support plate 8, thereby adjusting the tilt angle of the antenna body 3. Without disassembling the installed base station antenna, the overall angle can be adjusted, which is convenient for use.

[0051] Such as Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10As shown, the locking mechanism 11 includes a fixed long plate 1101, an adjusting strip 1102, a locking member 1103, connecting side plates 1104 and a connecting spring 1105. The adjusting strip 1102 is fixedly connected to the inner side of the fixed long plate 1101. The connecting side plates 1104 are symmetrically arranged. The adjusting strip 1102 is located on the opposite side of the connecting side plates 1104. The locking member 1103 is fixedly connected to the upper side of the connecting side plates 1104 through a rotating shaft, and the locking member 1103 is movably connected to both sides of the adjusting strip 1102. One end of the connecting spring 1105 is fixedly connected to the outer side of the connecting side plates 1104. The top end of the fixed long plate 1101 is fixedly connected to the bottom end of the backing plate 1001. The adjusting strip 1102 is located below the backing plate 1001. The bottom end of the support plate 8 is fixedly connected with a support base 18, and the support base 18 is fixedly connected to the front end of the mounting frame 2. The other end of the connecting spring 1105 is fixedly connected to the inner side of the support base 18. A straight groove 19 is formed on the upper side of the support base 18, and both ends of the connecting side plates 1104 are respectively movably connected to the inner side of the straight groove 19. A plurality of fixing grooves 20 are respectively formed on both sides of the adjusting strip 1102, and the fixing grooves 20 are arranged in a linear array. The front ends of the locking members 1103 are respectively movably connected to the inner sides of the fixing grooves 20, and the locking strips are respectively adapted to the fixing grooves 20.

[0052] By simultaneously pushing the connecting side plates 1104 outward, the connecting spring 1105 is compressed at the same time, so that the locking member 1103 is away from the fixing grooves 20 on both sides of the adjusting strip 1102. Then, the fixed long plate 1101 is pulled downward, so that the fixed long plate 1101 drives the adjusting strip 1102 to move downward, and at the same time drives the backing plate 1001 to move downward to adjust the inclination angle of the antenna body 3. When the adjustment reaches the appropriate angle, the connecting side plates 1104 are released. Under the action of the connecting spring 1105, the connecting side plates 1104 move inward at the same time, so that the locking member 1103 is inserted into the fixing grooves 20 on both sides of the adjusting strip 1102 to fix and limit the adjusting strip 1102, thereby fixing the angle of the antenna body 3.

[0053] Working principle: When in use, insert the mounting bracket 2 into the inner side of the connecting base 5 so that the fixing plate 7 is located inside the connecting base 5. Then, rotate the fixing rods 601 respectively to make the first clamping plate 603 and the second clamping plate 604 move inward in the connecting base 5, making the first clamping plate 603 and the second clamping plate 604 approach each other until the first clamping plate 603 is in contact with the second clamping plate 604. At this time, the front ends of the first clamping plate 603 and the second clamping plate 604 are respectively inserted into the fixing card slots 14 on both sides of the fixing plate 7 to fix the mounting bracket 2 to the connecting base 5, thereby fixing the antenna body 3 on the upper side of the support vertical pole 1. When disassembling the base station antenna, just rotate the fixing rods 601 outward to make the first clamping plate 603 and the second clamping plate 604 move away from the fixing plate 7, and then the base station antenna can be disassembled, which is convenient for installing and quickly disassembling the base station antenna. When it is necessary to adjust the tilt angle of the base station antenna, first push the connecting side plates 1104 outward simultaneously, and at the same time, the connecting springs 1105 are compressed, making the locking fasteners 1103 move away from the fixing slots 20 on both sides of the adjusting card strip 1102. Then, pull down the fixing long plate 1101, making the fixing long plate 1101 drive the adjusting card strip 1102 to move downward, and at the same time drive the cushion plate 1001 to move downward, making the connecting rod 1002 drive the linkage plate 1003 to rotate downward. At the same time, the linkage rod 1004 slides backward in the moving slots 15 on both sides of the support plate 8, making the lower side of the mounting guide plate 1005 rotate inward around the support plate 8, and at the same time drive the antenna body 3 to rotate inward. On the contrary, push up the fixing long plate 1101 to make the cushion plate 1001 move upward, and at the same time drive the linkage plate 1003 to rotate upward, then the lower side of the mounting guide plate 1005 can rotate outward around the support plate 8, thereby adjusting the tilt angle of the antenna body 3. When the appropriate angle is adjusted, release the connecting side plates 1104, and under the action of the connecting springs 1105, make the connecting side plates 1104 move inward simultaneously, making the locking fasteners 1103 insert into the fixing slots 20 on both sides of the adjusting card strip 1102 to fix and limit the adjusting card strip 1102, thereby fixing the angle of the antenna body 3.
