[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a performance detection device for a fish-tail antenna, including a base 1, a panel 2 is fixedly connected to the upper surface of the base 1, a control center 3 is fixedly connected to the upper surface of the panel 2, a slide rail 4 is fixedly connected to the upper surface of the panel 2, a sliding door 5 is slidably connected to the inner surface of the slide rail 4, a handle 6 is fixedly connected to one side surface of the sliding door 5, a housing 7 is slidably connected to one side surface of the sliding door 5, a signal receiver 8 is fixedly connected to the upper surface of the panel 2, a lifting mechanism 9 is arranged on the upper surface of the panel 2, a connecting shaft 10 is arranged on one side surface of the lifting mechanism 9, and a detection mechanism 11 is arranged on the inner surface of the connecting shaft 10;

[0022] The detection mechanism 11 includes a driving motor 1101, a fixing block 1102, a fixing groove 1103, a bolt 1104, a knob 1105, a backing plate 1106, a connecting plate 1107 and a signal generator 1108. The driving motor 1101 is rotatably connected to the inner surface of the connecting shaft 10. A fixing block 1102 is fixedly connected to one side surface of the driving motor 1101. A fixing groove 1103 is formed in the inner surface of the fixing block 1102. A bolt 1104 is threadedly connected to the inner surface of the fixing groove 1103. A knob 1105 is fixedly connected to one end of the bolt 1104. The other end of the bolt 1104 is rotatably connected to a backing plate 1106. A connecting plate 1107 is fixedly connected to the lower surface of the fixing block 1102. A signal generator 1108 is fixedly connected to the lower surface of another group of fixing blocks 1102. Through the settings of the driving motor 1101, the fixing block 1102, the fixing groove 1103, the bolt 1104, the knob 1105, the backing plate 1106, the connecting plate 1107 and the signal generator 1108, when in use, the fish-tail antenna is inserted into the signal generator 1108 through the fixing block 1102. The bolt 1104 in the fixing groove 1103 can be tightened or loosened by rotating the knob 1105. When the bolt 1104 is tightened, the backing plate 1106 will press the fish-tail antenna to achieve stable connection and fixation. The driving motor 1101 is installed on the connecting shaft 10 and can rotate on the inner surface of the connecting shaft 10. Starting the driving motor 1101 drives the fixing block 1102 to rotate, thereby driving the fish-tail antenna to rotate, realizing the performance detection of the antenna in different directions.

[0023] Furthermore, an observation window is provided on the surface of the sliding door 5, and an electromagnetic wave absorbing material is coated on the inner surface of the outer shell 7. With the settings of the sliding door 5 and the outer shell 7, during use, the outer shell 7 is made of a metal material and coated with an electromagnetic wave absorbing material inside, which can effectively absorb and reflect external electromagnetic waves to reduce the influence of external electromagnetic interference on the detection results.

[0024] Furthermore, the inner wall dimensions of the fixing groove 1103 match the outer wall dimensions of the backing plate 1106. The fixing groove 1103 is symmetrically arranged with respect to the central axis of the fixing block 1102. With the settings of the fixing groove 1103 and the backing plate 1106, during use, the backing plate 1106 slides inside the fixing groove 1103, and the fixing groove 1103 limits the backing plate 1106 to make the movement of the backing plate 1106 more stable.

[0025] Furthermore, there are two groups of fixing blocks 1102, which are fixedly connected to both ends of the connecting plate 1107. With the setting of the fixing blocks 1102, during use, the fish-tail antenna can be fixed to make the detection of the fish-tail antenna more stable.

[0026] Furthermore, the lifting mechanism 9 includes a bracket 901, a limiting groove 902, a limiting block 903, a lifting plate 904, a threaded rod 905, and a servo motor 906.

The upper surface of the lifting plate 904 is threadedly connected with the threaded rod 905. One end of the threaded rod 905 is fixedly connected with the servo motor 906. One side surface of the lifting plate 904 is fixedly connected with a connecting shaft 10. With the settings of the bracket 901, the limiting groove 902, the limiting block 903, the lifting plate 904, the threaded rod 905, and the servo motor 906, during use, start the servo motor 906 to drive the threaded rod 905 fixedly connected thereto to rotate. When the threaded rod 905 rotates, it will drive the lifting plate 904 to move in the vertical direction. During the movement of the lifting plate 904, the limiting block 903 fixed on one side of it slides in the limiting groove 902 on the inner surface of the bracket 901. The cooperation between the limiting groove 902 and the limiting block 903 plays a role in guiding and restricting the moving direction of the lifting plate 904, preventing the lifting plate 904 from rotating or shifting, ensuring that it can stably lift vertically, and the connecting shaft 10 will move synchronously with the lifting and lowering of the lifting plate 904 to realize the performance detection of the fish-tail antenna at different heights.

[0027] Furthermore, there are two groups of brackets 901, and the lifting plate 904 and the servo motor 906 form a rotating structure through the threaded rod 905. With the setting of the brackets 901, during use, the two groups of brackets 901 provide a stable support and guiding framework for the entire lifting structure.

[0028] Furthermore, the inner wall dimensions of the limit groove 902 match the outer wall dimensions of the limit block 903. The limit blocks 903 are symmetrically arranged with respect to the central axis of the lifting plate 904. The arrangement of the limit groove 902 and the limit blocks 903 enables the limit blocks 903 to slide within the limit groove 902 during use, and the limit groove 902 limits the limit blocks 903, making the lifting of the lifting plate 904 more stable.

[0029] Working principle: The signal generator 1108 can generate signals with various frequencies and powers required for detection. The signals are received by the signal receiver 8 and displayed in the control center 3, and spectral analysis is performed on them to obtain performance parameters such as the frequency response, gain, and directivity of the antenna. The fish-tail antenna is inserted into the signal generator 1108 through the fixing block 1102. The bolt 1104 in the fixing groove 1103 can be tightened or loosened by rotating the knob 1105. When the bolt 1104 is tightened, the backing plate 1106 will press tightly against the fish-tail antenna to achieve firm connection and fixation. The sliding door 5 is pulled up through the slide rail 4. The outer shell 7 is made of metal material and coated with wave-absorbing material inside, which can effectively absorb and reflect external electromagnetic waves to reduce the influence of external electromagnetic interference on the detection results. The servo motor 906 is started to drive the threaded rod 905 fixedly connected thereto to rotate. When the threaded rod 905 rotates, it will drive the lifting plate 904 to move in the vertical direction. During the movement of the lifting plate 904, the limit blocks 903 fixed on one side thereof slide within the limit groove 902 on the inner surface of the bracket 901. The cooperation between the limit groove 902 and the limit blocks 903 plays a role in guiding and restricting the moving direction of the lifting plate 904, preventing the lifting plate 904 from rotating or deviating, and ensuring that it can stably lift vertically. The connecting shaft 10 will move synchronously with the lifting of the lifting plate 904 to achieve performance detection of the fish-tail antenna at different heights. The driving motor 1101 is installed on the connecting shaft 10 and can rotate on the inner surface of the connecting shaft 10. The driving motor 1101 is started to drive the fixing block 1102 to rotate, thereby driving the fish-tail antenna to rotate to achieve performance detection of the antenna in different directions, and thus can meet the detection requirements of the fish-tail antenna. The models of the servo motor 507 and the driving motor 406 are YE2-132S-4.

The scope of the present invention is defined by the appended claims and their equivalents.
