Description

Technical Field

[0001] The utility model relates to the technical field of spectrum analyzers, in particular to a spectrum analyzer for antenna testing. Background Art

[0002] Antenna testing is an important task in the field of wireless communications. As a key component of wireless communication systems, the performance of antennas directly affects the signal transmission quality and the overall performance of communication systems. Therefore, accurate and comprehensive testing of antennas is essential. Spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation, spectral purity, frequency stability and intermodulation distortion. It can be used to measure certain parameters of circuit systems such as amplifiers and filters. It is a multi-purpose electronic measuring instrument.

[0004] Although the above scheme is equipped with a handle and an anti-drop pad to prevent the spectrum analyzer from being damaged, during the antenna test, in order to ensure that the signal can be accurately and effectively transmitted from the antenna to the spectrum analyzer, the two will be connected through a data cable. If the operator walks carelessly during the detection process, the connection may fall off. The device lacks the function of clamping and fixing the interface cable, and it is difficult to perform normal detection in the event of an accident. Therefore, it does not meet the existing needs. In this regard, we propose a spectrum analyzer for antenna testing. Utility Model Content

[0005] The utility model aims to provide a spectrum analyzer for antenna testing, so as to solve the problem in the background art that the spectrum analyzer interface lacks a fixing function and is difficult to fix when a cable falls off, affecting normal detection.

[0006] To achieve the above object, the utility model provides the following technical solution: a spectrum analyzer for antenna testing, comprising a spectrum analyzer body, wherein a fixing block is fixedly bonded to and fixed to the upper and lower parts of the rear end of the spectrum analyzer body;

[0007] It also includes a double-threaded transmission rod, which is arranged between the fixed blocks and is rotatably connected to the fixed blocks, and the upper and lower sides of the double-threaded transmission rod are both threadedly connected to the lifting blocks;

[0008] It also includes an extrusion cavity, which is opened inside the lifting block, and a number of extrusion cavities are evenly distributed. A connecting plate is arranged inside the extrusion cavity, and a clamping block is adhesively fixed to one end of the connecting plate, and one end of the clamping block is exposed to the outside of the user's extrusion cavity.

[0009] Preferably, a transmission cavity is opened on one side of one of the fixed blocks, a second rotating shaft is rotatably arranged on the upper end of the transmission cavity, and the second rotating shaft is connected to the double-threaded transmission rod through a coupling, a first rotating shaft is arranged on one side of the second rotating shaft, one end of the first rotating shaft extends to the outside of the transmission cavity, and the first rotating shaft rotates in cooperation with the transmission cavity, bevel gears are arranged on one end of the first rotating shaft located inside the transmission cavity and on the outer wall of the second rotating shaft, and the bevel gears are meshedly connected, and a knob is installed on one end of the first rotating shaft located outside the transmission cavity.

[0010] Preferably, second guide rods are bonded and fixed on both sides of the extrusion cavity, the second guide rods pass through the connecting plate, and the second guide rods are slidably matched with the connecting plate, and the outside of the second guide rods is sleeved with a return spring, one end of the return spring is connected to the extrusion cavity, and the other end of the return spring is connected to the connecting plate.

[0011] Preferably, four equally spaced suction cups are provided on both sides of the lower end of the spectrum analyzer body.

[0012] Preferably, an anti-slip pad is adhered and fixed at the middle position of the lower end of the spectrum analyzer body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model has a double-threaded transmission rod that is rotatably arranged between the fixed blocks. When the data cable is connected to the interface, the operator can turn the knob, and the knob will rotate the double-threaded transmission rod under the meshing transmission of the bevel gear. The double-threaded transmission rod will drive the two lifting blocks to move toward each other, and the lifting blocks will drive the clamping blocks to move synchronously, and then the data cable can be clamped and fixed by the two clamping blocks that move toward each other. When there is an external force pulling, the data cable will not fall off easily, thereby ensuring the continuity and stability of the antenna test.

[0017] 2. The utility model opens an extrusion cavity inside the lifting block. Since the wire diameters of data cables of different models are also different, when the clamping blocks move toward each other to clamp and fix the data cables, the clamping blocks will drive the connecting plates to squeeze the reset springs. The elastic action of the reset springs enables the clamping blocks to make small-range autonomous adjustments according to the wire diameters of the data cables when clamping the data cables, thereby adapting to the clamping requirements of different wire diameters and improving practicality.

[0018] 3. The utility model provides a suction cup, a moisture-absorbing pad and an anti-skid pad at the lower end of the spectrum analyzer body. The setting of the suction cup can enhance the adsorption force between the spectrum analyzer body and the placement surface, ensuring that it is not easily displaced due to external interference during the test process, thereby improving the accuracy and stability of the test. The setting of the moisture-absorbing pad can effectively isolate the moisture on the ground or the table and prevent moisture from invading the interior of the spectrum analyzer body. The setting of the anti-skid pad further enhances the stability of the spectrum analyzer body, providing a strong guarantee for the antenna test work. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 4 , second guide rods 13 are bonded and fixed on both sides of the extrusion cavity 11, the second guide rods 13 pass through the connecting plate 12, and the second guide rods 13 are slidably matched with the connecting plate 12, and the outer part of the second guide rods 13 is sleeved with a return spring 14, one end of the return spring 14 is connected to the extrusion cavity 11, and the other end of the return spring 14 is connected to the connecting plate 12. The elastic action of the return spring 14 can make the clamping block 15 self-adjust in a small range according to the wire diameter of the data line, so as to adapt to the clamping requirements of different wire diameters and improve practicality;

[0032] See also Figure 1 , Figure 2 and Figure 3 , four equally spaced suction cups 16 are provided on both sides of the lower end of the spectrum analyzer body 1, and the suction cups 16 are adsorbed on the placement surface to ensure that the spectrum analyzer body 1 is not easily displaced due to external force interference during the test process;

[0033] See also Figure 1 and Figure 3 A non-slip pad 18 is adhered and fixed at the middle position of the lower end of the spectrum analyzer body 1. The provision of the non-slip pad 18 can further enhance the stability of the spectrum analyzer body 1;

[0035] See also Figure 1 A first guide rod 5 is welded on one side between the fixed blocks 2, and the first guide rod 5 passes through the lifting block 4, and the first guide rod 5 slides with the lifting block 4. The setting of the first guide rod 5 realizes the axial limit of the lifting block 4, so that the rotation of the lifting block 4 can be converted into up and down vertical movement, thereby driving the clamping block 15 to clamp and fix the data line.

[0036] Working principle: When in use, place the spectrum analyzer body 1 and press it gently, so that the suction cup 16 can be adsorbed on the placement surface, ensuring that the spectrum analyzer body 1 is not easily displaced due to external interference during the test, avoiding the risk of the data line being disconnected, and by providing a moisture-absorbing pad 17, moisture can be prevented from invading the interior of the spectrum analyzer body 1. In an environment with high humidity, the service life of the spectrum analyzer body 1 can be effectively extended to ensure the reliable performance of the antenna test. The provision of the anti-slip pad 18 can further enhance the stability of the spectrum analyzer body 1, providing a strong guarantee for the antenna test work. After fixing the spectrum analyzer body 1, the data line can be inserted. After the data line is connected, the knob 6 is turned, and the knob 6 will drive the first shaft 7 to rotate, and the first shaft 7 will drive one of the bevel gears 9 to rotate synchronously. Since the two bevel gears 9 are meshed and connected, the other bevel gear 9 will be driven to make the second shaft 10 rotate synchronously. When the first guide rod 5 is moved, the second rotating shaft 10 will drive the double-threaded transmission rod 3 to rotate synchronously, and the double-threaded transmission rod 3 will drive the two lifting blocks 4 to rotate synchronously. The two lifting blocks 4 are both slidably matched with the first guide rod 5, so they are both limited in the axial direction. The rotation of the two lifting blocks 4 will be converted into opposite or opposite vertical movements up and down. When the two lifting blocks 4 move towards each other, they will drive the clamping block 15 to move synchronously, so that the data line in the middle can be clamped and fixed, so that the data line will not fall off easily, thereby ensuring the continuity and stability of the antenna test. When the clamping block 15 clamps and fixes the data line, it will drive the connecting plate 12 to squeeze the reset spring 14. When the diameter of the data line is small, the elastic force of the reset spring 14 will push the clamping block 15 to fit the data line more closely to ensure the stability of the clamping. When the diameter of the data line is large, the reset spring 14 can allow the clamping block 15 to move slightly outward to adapt to the clamping requirements of different line diameters, thereby increasing practicality.
