Description

Technical Field

[0001] This utility model relates to the field of antenna testing equipment technology, and in particular to a 5G communication antenna test frame. Background Technology

[0002] As a key component for signal transmission and reception, the performance of antennas directly affects the efficiency and stability of the entire 5G communication system. Precise antenna testing can verify the antenna's performance parameters, such as gain, directivity, bandwidth, and reflection loss, to ensure that these parameters meet design requirements, thereby guaranteeing the coverage, signal quality, and transmission efficiency of the communication system.

[0003] Therefore, during the production of communication antennas, it is necessary to test their communication signals, especially for outdoor communication antennas. The performance requirements are higher due to the environment and installation conditions. To ensure the testing conditions closely resemble actual usage, the antenna is installed at a certain height. The antenna's installation angle determines the geographical area and range of signal coverage. An improper angle may result in ineffective signal coverage of the intended area, leading to blind spots or signal overlap. Furthermore, the antenna's directivity determines the main transmission path; proper direction setting can enhance signal strength in the target area and reduce interference. Therefore, during antenna testing, the antenna's mounting surface can be angled, typically using fasteners and bolts. However, this method makes adjusting the antenna's tilt and horizontal angles inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a 5G communication antenna test fixture, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A 5G communication antenna test frame includes a signal antenna and a mounting column. A connecting buckle and an arc-shaped frame are fixedly installed on one side of the signal antenna. A guide rod is movably installed inside the arc-shaped frame. A steering column is rotatably installed on the mounting column. An installation through groove is opened in the steering column. An adjusting rod is rotatably installed in the installation through groove. A lead screw is movably installed at the lower end of the adjusting rod. A fixing rod is also fixedly installed on the steering column located below the installation through groove. A sleeve is rotatably installed on one side of the fixing rod. A first handwheel is movably installed at the lower end of the sleeve. Two base plates are fixedly installed at the lower end of the fixing rod. A worm gear is rotatably installed between the two base plates. A sector-shaped frame is also fixedly installed on the signal antenna located below the steering column. Multiple worm gear teeth are fixedly installed on the outer side of the sector-shaped frame and mesh with the worm gear.

[0007] As a further preferred embodiment of this utility model, a guide groove is provided inside the mounting column, and two mounting brackets are axially connected to the outer side of the mounting column, and the mounting brackets are installed on an external carrier.

[0008] As a further preferred embodiment of this utility model, the lower end of the adjusting rod is fixedly installed with two fixed seats, and the upper end of the lead screw is axially connected between the two fixed seats.

[0009] As a further preferred embodiment of this utility model, a retaining ring is fixedly installed at the lower end of the sleeve.

[0010] As a further preferred embodiment of this utility model, the first handwheel also includes an adjusting block and a ring. Multiple connecting rods are fixedly connected between the rings. A rotating groove is provided on the outer side of the adjusting block. The upper end of the adjusting block is rotatably installed in the fixed ring through the rotating groove. The lower end of the lead screw passes through the sleeve and is threadedly connected to the screw hole in the middle of the adjusting block. Rotating the first handwheel on the lower end of the sleeve allows the adjusting block to control the lifting and lowering of the lead screw when it rotates on the outside of the lead screw through the internal screw hole. This, in turn, changes the tilt angle of the signal antenna by changing the angle of the adjusting rod.

[0011] As a further preferred embodiment of this utility model, bushings are fixedly installed on one side of each of the two base plates, and the two sides of the worm gear extend through the corresponding bushings to one side of the bushings. A second handwheel is also fixedly installed on one side of the worm gear. By rotating the worm gear, the worm gear rotates on the worm wheel teeth on the outside of the sector frame, which can cooperate with the base plate and the fixed rod to drive the steering column to rotate on the mounting column, thereby adjusting the orientation of the signal antenna.

[0012] As a further preferred embodiment of this utility model, a sliding groove is provided inside the arc-shaped frame. One side of the guide rod passes through the sliding groove inside the arc-shaped frame and is fixedly installed with a limit block. The other side of the guide rod passes through the guide groove and is threaded with a nut. A pad is also inserted and installed on the outer side of the guide rod near the arc-shaped frame. A compression spring is also fitted on the guide rod located between the sleeve and the pad. An arc-shaped frame is set at the lower end of the signal antenna, and one side of the guide rod inside the arc-shaped frame is inserted into the guide groove. This, together with the compression spring, provides stable support for the lower end of the signal antenna when the antenna is tilted, preventing the signal antenna from reflecting and shaking.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the signal antenna is movably mounted between the adjusting rod and the mounting column via a connecting buckle, an arc-shaped frame, and a guide rod. It can be used with a lead screw, a fixing rod, a sleeve, and a first handwheel to quickly adjust the tilt angle of the signal antenna. The fan-shaped frame and worm gear, together with the fixing rod, can drive the steering column to rotate on the mounting column, thereby coordinating with the adjusting rod to drive the signal antenna to rotate horizontally. This facilitates the adjustment of the signal antenna's orientation, thus improving the adjustment efficiency during signal antenna testing. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5As shown, the present invention provides a 5G communication antenna test frame, including a signal antenna 1 and a mounting column 2. A connecting buckle 3 and an arc-shaped frame 4 are fixedly installed on one side of the signal antenna 1. A guide rod 5 is movably installed inside the arc-shaped frame 4. A steering column 6 is rotatably installed on the mounting column 2. A mounting slot 7 is opened inside the steering column 6. An adjusting rod 8 is rotatably installed inside the mounting slot 7. A lead screw 9 is movably installed at the lower end of the adjusting rod 8. A fixing rod 10 is also fixedly installed on the steering column 6 located below the mounting slot 7. A sleeve 11 is rotatably installed on one side of the fixing rod 10. A first handwheel 12 is movably installed at the lower end of the sleeve 11. Two base plates 13 are fixedly installed at the lower end of the fixing rod 10. A worm gear 14 is rotatably installed between the two base plates 13. A sector-shaped frame 15 is also fixedly installed on the signal antenna 1 located below the steering column 6. Multiple worm gear teeth are fixedly installed on the outer side of the sector-shaped frame 15 and mesh with the worm gear 14.

[0023] like Figures 1-5 As shown, the mounting column 2 has a guide groove 16 inside, and two mounting brackets 17 are axially connected to the outside of the mounting column 2. The mounting brackets 17 are installed on the external carrier. Two fixed seats 18 are fixedly installed at the lower end of the adjusting rod 8. The upper end of the lead screw 9 is axially connected between the two fixed seats 18. A fixed ring 19 is fixedly installed at the lower end of the sleeve 11. The first handwheel 12 also includes an adjusting block 20 and a wheel ring 21. Multiple connecting rods are fixedly connected between the wheel rings 21. A rotating groove 22 is opened on the outside of the adjusting block 20. The upper end of the adjusting block 20 is rotatably installed in the fixed ring 19 through the rotating groove 22. The lower end of the lead screw 9 passes through the sleeve 11 and is threaded into the screw hole in the middle of the adjusting block 20. Rotating the first handwheel 12 to the lower end of the sleeve 11 allows the adjusting block 20 to control the lifting and lowering of the lead screw 9 when rotating outside the lead screw 9 through the internal screw hole. This changes the tilt angle of the signal antenna 1 by changing the angle of the adjusting rod 8.

[0024] like Figures 1-4As shown, bushings 23 are fixedly installed on one side of each of the two base plates 13. The worm gear 14 extends through the corresponding bushings 23 on both sides. A second handwheel 24 is also fixedly installed on one side of the worm gear 14. By rotating the worm gear 14, it rotates on the worm wheel teeth on the outside of the sector frame 15, thus cooperating with the base plate 13 and the fixed rod 10 to drive the steering column 6 to rotate on the mounting column 2, thereby adjusting the orientation of the signal antenna 1. A groove is provided inside the arc frame 4. One side of the guide rod 5 passes through the groove inside the arc frame 4 and is fixedly installed with... The limit block 25 and the guide rod 5 pass through the guide groove 16 on the other side and are threaded with a nut. A pad 26 is also installed on the outer side of the guide rod 5 near the arc frame 4. A compression spring 27 is also fitted on the guide rod 5 between the sleeve 11 and the pad 26. An arc frame 4 is set at the lower end of the signal antenna 1, and one side of the guide rod 5 in the arc frame 4 is inserted into the guide groove 16. This can work with the compression spring 27 to provide stable support for the lower end of the signal antenna 1 when the tilt angle of the signal antenna 1 is adjusted, and prevent the signal antenna 1 from reflecting and shaking.

[0025] It should be noted that this utility model is a 5G communication antenna test frame. When testing the signal antenna 1, one side of each of the two mounting brackets 17 on the outer side of the mounting column 2 can be fixedly mounted on the external carrier. Subsequently, the lower port of the signal antenna 1 can be connected to an external communication device via a connecting cable, and the signal antenna 1 can be used to receive and process signals at a distance, thereby cooperating with a remote signal detection device to test the communication quality of the signal antenna 1. When it is necessary to adjust the tilt angle and orientation of the signal antenna 1, the wheel ring 21 can be manually rotated. Therefore, the wheel ring 21 drives the adjusting block 20 to rotate through multiple connecting rods, while the upper end of the adjusting block 20 rotates within the fixed ring 19 through the outer rotating groove 22. Thus, the screw hole within the adjusting block 20 rotates outside the lead screw 9. The height adjustment of the lead screw 9 within the sleeve 11 and adjusting block 20 can be controlled by the reverse rotation of the adjusting block 20. This allows the upper end of the lead screw 9 to rotate between the two fixed seats 18, raising or lowering one end of the adjusting rod 8. Consequently, the adjusting rod 8 rotates around the shaft connected in the mounting slot 7, thereby... The other end of the adjusting rod 8 drives the signal antenna 1 to adjust its tilt angle. When the signal antenna 1 is adjusting its tilt angle, the arc-shaped frame 4 at the lower side of the signal antenna 1, together with the limiting block 25, pushes the guide rod 5 towards the signal antenna 1, and makes one side of the guide rod 5 move within the guide groove 16. At the same time, the arc-shaped frame 4 compresses the compression spring 27 towards the signal antenna 1 through the pad 26, thereby using the reaction force of the compressed spring 27 to support the lower half of the signal antenna 1, thus ensuring the stability of the tilt angle adjustment of the signal antenna 1. To adjust the horizontal direction of the signal antenna 1, simply turn the second handwheel 24. The second handwheel 24 rotates within the two bushings 23, and the worm gear 14 rotates on the worm wheel teeth on the outside of the sector frame 15. This allows the base plate 13 to move along the outer contour of the sector frame 15, thereby cooperating with the base plate 13 and the fixed rod 10 to drive the steering column 6 to rotate on the mounting column 2. In turn, the steering column 6, in conjunction with the adjusting rod 8, drives the signal antenna 1 to rotate horizontally around the mounting column 2 as the axis. Meanwhile, the arc frame 4 slides on the guide rod 5 through the internal groove.
