Description

Technical Field

[0001] This application relates to the field of communication antenna technology, and in particular to a detachable radome and a communication antenna. Background Technology

[0002] Communication antennas are used for signal transmission. Signals are received and then forwarded through communication antennas to expand the signal coverage area, thereby realizing the transmission between signals. It is one of the important infrastructures in modern society.

[0003] A communication antenna generally consists of an antenna body and an antenna cover. The antenna body is installed inside the antenna cover, which protects the antenna body from the effects of harsh external environments (such as strong winds, heavy rain, and blizzards) and ensures the accuracy of the antenna.

[0004] Currently, radomes mainly consist of an upper radome and a lower radome. The lower radome has a boss with threaded holes, and the upper and lower radomes are connected and fixed with bolts. During antenna use, technicians frequently test or maintain the antenna body, resulting in numerous disassemblies of the radome. This can damage the threaded holes on the boss, necessitating the replacement of the entire lower radome. Replacement is costly, and since the antenna body is mounted on the lower radome, the workload during replacement is substantial, requiring further adjustments afterward. Therefore, this application proposes a detachable radome and a communication antenna. Utility Model Content

[0005] This application provides a detachable radome and communication antenna, which can be disassembled and assembled. If the threaded hole on the boss is damaged, only the ring connecting component needs to be replaced. There is no need to replace the lower cover, disassemble the antenna body, or perform subsequent debugging. The process is simple, easy to operate, and ensures the accuracy of the entire antenna.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] The first aspect of this application provides a detachable radome, including a lower radome, an upper radome, and an annular connecting assembly. The lower radome has an upper opening and a plurality of first through holes on its circumferential wall. The upper radome has a lower opening and a plurality of second through holes on its circumferential wall, the number of which is equal to the number of the first through holes. An annular mounting plate is provided inside the upper radome, and a plurality of first threaded holes are provided on the annular mounting plate. The annular connecting assembly includes an annular horizontal plate and an annular vertical plate. The annular horizontal plate is connected to the upper end of the annular vertical plate and is located inside the annular vertical plate. The annular horizontal plate has a plurality of third through holes, the number of which is equal to the number of the first threaded holes. The annular vertical plate has a plurality of bosses, the number of which is equal to the number of the second through holes. Each boss has a second threaded hole. When the annular horizontal plate is mounted on the annular mounting plate, the second through holes and the second threaded holes are coaxial. The third through holes and the first threaded holes are connected by first bolts, and the first through holes, the second through holes, and the second threaded holes are connected by second bolts.

[0008] In use, the annular horizontal plate of the annular connecting assembly is mounted onto the annular mounting plate of the upper cover using the first bolt, making the second through hole and the second threaded hole coaxial. The lower cover, upper cover, and annular connecting assembly are then assembled together using the first bolt, completing the installation of the entire radome.

[0009] Compared to existing technologies, this detachable radome allows for easy assembly and disassembly. If the threaded hole on the boss is damaged, only the ring-shaped connecting assembly needs to be replaced, eliminating the need to replace the lower cover and reducing replacement costs. Furthermore, it eliminates the need to disassemble the antenna body and perform subsequent adjustments, making the process simple, easy to operate, and ensuring the accuracy of the entire antenna.

[0010] In one embodiment of this application, the upper cover, the lower cover, and the annular vertical plate are arranged sequentially from the outside to the inside.

[0011] In one embodiment of this application, the annular vertical plate includes an upper vertical plate and a lower vertical plate. The upper vertical plate is connected to the annular horizontal plate, and the lower vertical plate is connected to the upper vertical plate. The boss is disposed on the lower vertical plate, and the outer edge of the lower vertical plate is closer to the center of the annular horizontal plate than the outer edge of the upper vertical plate.

[0012] In one embodiment of this application, when the upper end of the lower cover abuts against the lower end of the upper vertical plate, the first through hole and the second through hole are coaxial.

[0013] In one embodiment of this application, an annular sealing gasket is provided between the lower cover and the lower vertical plate.

[0014] In one embodiment of this application, the number of the first through hole and the number of the first threaded hole are both 8.

[0015] In one embodiment of this application, the annular horizontal plate and the annular vertical plate are integrally formed.

[0016] A second aspect of this application provides a communication antenna, including an antenna body and a detachable antenna cover as described in the first aspect, wherein the antenna body is mounted on the lower cover.

[0017] Compared to existing technologies, this communication antenna includes a detachable radome. If the threaded hole on the boss is damaged, only the ring-shaped connecting assembly needs to be replaced. There is no need to replace the lower cover, disassemble the antenna body, or perform subsequent debugging. The process is simple, easy to operate, and ensures the accuracy of the entire communication antenna. Attached Figure Description

[0029] Figure 1 This is an exploded view of a detachable radome provided in one embodiment of this application. Figure 2 This is a cross-sectional view of a detachable radome provided in one embodiment of this application. Figure 3 for Figure 2 A magnified view of a portion of point A in the middle. Figure 4 This is a three-dimensional structural diagram of a communication antenna provided in an embodiment of this application, with the upper cover and lower cover separated.

[0030] An embodiment of the first aspect of this application provides a detachable radome 100, such as Figure 1 and Figure 2 As shown, it includes a lower cover 200, an upper cover 300, and an annular connecting assembly 400. The lower cover 200 is a component for mounting the antenna body, the upper cover 300 is a component for covering the antenna body, and the annular connecting assembly 400 is a component for connecting the upper cover 300 and the lower cover 200.

[0031] like Figure 1 As shown, the lower cover 200 has an opening at the upper end, and the circumferential wall of the lower cover 200 is provided with a plurality of first through holes 210, which are evenly distributed along the circumference of the lower cover 200.

[0032] like Figure 1 As shown, the lower end of the upper cover 300 is open, and the circumferential wall of the upper cover 300 is provided with a plurality of second through holes 310. The number of the plurality of second through holes 310 is equal to the number of the plurality of first through holes 210, and the plurality of second through holes 310 are evenly distributed along the circumference of the upper cover 300.

[0033] Generally, the upper cover 300 mainly consists of a hemispherical structure and a cylindrical structure, which are connected together. The configuration can be referenced from existing technologies and will not be described in detail here.

[0034] like Figure 3 As shown, the upper cover 300 has an annular mounting plate 320 inside, and the annular mounting plate 320 has multiple first threaded holes 330, which are evenly distributed along the circumference of the annular mounting plate 320. The annular mounting plate 320 is located near the lower end of the upper cover 300, which is equivalent to forming a rib near the opening of the upper cover 300, which can enhance the structural stability of the upper cover 300 and improve the stability of the entire radome.

[0035] like Figure 3 As shown, the annular connecting assembly 400 includes an annular horizontal plate 410 and an annular vertical plate 420. The annular horizontal plate 410 is connected to the upper end of the annular vertical plate 420 and is located inside the annular vertical plate 420. The cross-section of the annular connecting assembly 400 is generally L-shaped.

[0036] like Figure 3 As shown, the annular horizontal plate 410 is provided with a plurality of third through holes 430. The number of the plurality of third through holes 430 is equal to the number of the plurality of first threaded holes 330. The third through holes 430 and the first threaded holes 330 can be connected by a first bolt (not shown in the figure) so that the annular horizontal plate 410 can be installed on the annular mounting plate 320.

[0037] like Figure 3 As shown, the annular vertical plate 420 is provided with multiple bosses 440, the number of which is equal to the number of second through holes 310. Each boss 440 is provided with a second threaded hole 450. When the annular horizontal plate 410 is installed on the annular mounting plate 320, the second through hole 310 and the second threaded hole 450 are coaxial. In this way, the first through hole 210, the second through hole 310 and the second threaded hole 450 can be connected by a second bolt (not shown in the figure), thereby realizing the detachable connection between the upper cover 300 and the lower cover 200.

[0038] In use, the annular horizontal plate 410 of the annular connecting assembly 400 is installed onto the annular mounting plate 320 of the upper cover 300 using the first bolt, so that the second through hole 310 and the second threaded hole 450 are coaxial. The lower cover 200, the upper cover 300 and the annular connecting assembly 400 are then installed together using the first bolt to complete the installation of the entire radome.

[0039] Compared to existing technologies, the detachable radome 100 can be disassembled and assembled. If the threaded hole on the boss 440 is damaged, only the annular connecting component 400 needs to be replaced, without replacing the lower cover 200, reducing replacement costs. Furthermore, there is no need to disassemble the antenna body or perform subsequent debugging. The process is simple, easy to operate, and ensures the accuracy of the entire antenna.

[0040] In some implementations, such as Figure 3 As shown, the upper cover 300, the lower cover 200, and the annular vertical plate 420 are arranged sequentially from the outside to the inside, so that the upper cover 300 is outside the lower cover 200. Rainwater drips from the lower end of the upper cover 300 and will not enter the lower cover 200, thus improving the waterproof capability of the entire antenna cover.

[0041] In some embodiments, such as Figure 3 As shown, the annular vertical plate 420 includes an upper vertical plate 421 and a lower vertical plate 422. The upper vertical plate 421 is connected to the annular horizontal plate 410, and the lower vertical plate 422 is connected to the upper vertical plate 421. A boss 440 is disposed on the lower vertical plate 422, and the outer edge of the lower vertical plate 422 is closer to the center of the annular horizontal plate 410 than the outer edge of the upper vertical plate 421. In this way, when the annular horizontal plate 410 is installed on the annular mounting plate 320, a gap is formed between the lower vertical plate 422 and the upper cover 300, which allows the lower cover 200 to be inserted and installed.

[0042] In some embodiments, when the upper end of the lower cover 200 abuts against the lower end of the upper vertical plate 421, the first through hole 210 and the second through hole 310 are coaxial, so that the upper vertical plate 421 can play a positioning role, making it easy for the first through hole 210 and the second through hole 310 to be coaxially aligned.

[0043] In some embodiments, an annular sealing gasket is provided between the lower cover 200 and the lower vertical plate 422. The annular sealing gasket is sleeved on the outside of the lower vertical plate 422 to prevent moisture, dust and other substances from entering.

[0044] In some embodiments, the number of the first through hole 210 and the first threaded hole 330 are both 8, so that the annular connecting assembly 400 and the upper cover 300, as well as the upper cover 300 and the lower cover 200, are connected by 8 bolts, and the connection is firm.

[0045] In some embodiments, the annular horizontal plate 410 and the annular vertical plate 420 are integrally formed, avoiding subsequent installation processes and reducing installation steps.

[0046] An embodiment of the second aspect of this application provides a communication antenna 500, such as... Figure 4 As shown, it includes an antenna body 600 and a detachable radome 100 in the first aspect. The antenna body 600 is mounted on the lower cover 200, and the upper cover 300 covers the antenna body 600 to provide protection.

[0047] Compared to existing technologies, since the communication antenna 500 includes a detachable radome 100 in the first aspect, if the threaded hole on the boss 440 is damaged, only the annular connecting assembly 400 needs to be replaced. There is no need to replace the lower cover 200, nor to disassemble and reassemble the antenna body 600 or perform subsequent debugging. The process is simple and easy to operate, ensuring the accuracy of the entire communication antenna 500.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
