Description

Technical Field

[0001] This utility model relates to the field of spectrum analyzer technology, and in particular to a spectrum analyzer for antenna testing. Background Technology

[0002] A spectrum analyzer is an electronic test instrument used to measure the frequency components and amplitude of a signal. It can convert time-domain signals into frequency-domain signals and display them intuitively. It is widely used in communications, radio frequency, audio and other fields, and can help engineers analyze key parameters such as the spectral characteristics, harmonic distortion and noise interference of signals.

[0003] When testing an antenna, staff need to read key data such as the frequency, amplitude, and bandwidth of the signal through the display panel of the spectrum analyzer, and use the buttons or knobs on the instrument to adjust parameters such as the center frequency, sweep width, and reference level to optimize the test results. This process usually requires repeated adjustments and observations to ensure that the antenna performance meets the design requirements.

[0004] In actual testing scenarios, spectrum analyzers are usually placed directly on the workbench, and the instrument's display panel and operation buttons are often located on the front of the instrument. This layout forces operators to bend over to see the screen content and adjust parameters. For frequent operations or long-term tests, this posture not only easily leads to fatigue but also affects testing efficiency. Therefore, a spectrum analyzer for antenna testing is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 One embodiment of this utility model is a spectrum analyzer for antenna testing, which includes a spectrum analyzer body 1, a display screen 3 fixedly connected to the front of the spectrum analyzer body 1, and an adjustment mechanism 5 and a protective mechanism 6 provided on the outer wall of the spectrum analyzer body 1.

[0032] Reference Figures 2-3The adjustment mechanism 5 includes a crank arm 51, which is hinged to the side wall of the spectrum analyzer body 1. A support rod 52 is fixedly connected to the end of the crank arm 51 furthest from the spectrum analyzer body 1. The support rod 52, in conjunction with the crank arm 51, supports the spectrum analyzer body 1, allowing the display screen 3 of the spectrum analyzer body 1 to tilt upwards for the operator to observe and operate. A through groove 53 is provided on the crank arm 51. A bent rod 54 is slidably connected to the side wall of the spectrum analyzer body 1. The bent rod 54, through its sliding contact with the fixed shaft 55 and the through groove 53, can push the crank arm 51. The bent rod 54 has a "U"-shaped structure when viewed from above and an "L"-shaped structure when viewed from the side. The inner surface of the bent rod 54 is in contact with the outer wall of the spectrum analyzer body 1. The bent rod 54 is close to the crank arm 51. A fixed shaft 55 is fixedly connected to one side of the arm 51. The outer wall of the fixed shaft 55 is attached to the inner wall of the through groove 53. While the bent rod 54 slides on the side wall of the spectrum analyzer body 1, it can drive the bent arm 51 to rotate on the side wall of the spectrum analyzer body 1 in conjunction with the fixed shaft 55 and the through groove 53. A threaded sleeve 56 is fixedly connected to the top of the bent rod 54. A boss 57 is fixedly connected to the top of the spectrum analyzer body 1. A threaded rod 58 is rotatably connected through the inner wall of the boss 57. The threaded rod 58 is threadedly connected to the threaded sleeve 56. The rotation of the threaded rod 58, in conjunction with the threaded sleeve 56, drives the bent rod 54 to slide on the side wall of the spectrum analyzer body 1. A handle 59 is fixedly connected to the end of the threaded rod 58 near the boss 57. The handle 59 allows the operator to easily rotate the threaded rod 58.

[0033] Reference Figures 2-3 The protective mechanism 6 includes a baffle 61, which is slidably connected to the front of the spectrum analyzer body 1. By sliding the baffle 61 upwards, the display screen 3 on the front of the spectrum analyzer body 1 can be blocked, thereby protecting the display screen 3 during the carrying of the spectrum analyzer body 1. L-plates 62 are fixedly connected to both sides of the baffle 61. The cross-section of the L-plate 62 is an "L" shape. The side of the L-plate 62 closest to the ball joint 63 is inclined from top to bottom. When the ball joint 63 presses upwards against the L-plate 62… L-plate 62 will cause baffle 61 to slide upward on the front of the spectrum analyzer body 1. A ball head rod 63 is fixedly connected to one end of the bent rod 54 near L-plate 62. During the sliding of the bent rod 54 on the side wall of the spectrum analyzer body 1, the ball head rod 63 will move synchronously. The end of the ball head rod 63 away from the bent rod 54 is a hemispherical structure. When the spherical surface of the ball head rod 63 contacts the inclined surface of L-plate 62 during the movement, the ball head rod 63 will squeeze the inclined surface of L-plate 62, thereby causing the ball head rod 63 to squeeze L-plate 62 upward.

[0034] Working principle: During use, by rotating the threaded rod 58 through the handle 59, the threaded rod 58 rotates on the inner wall of the boss 57. At the same time, the threaded rod 58, in conjunction with the threaded sleeve 56 connected to it, can drive the bent rod 54 to slide on the side wall of the spectrum analyzer body 1. As the bent rod 54 moves closer to the boss 57, it will drive the fixed shaft 55 to move against the inner wall of the through groove 53. At this time, the fixed shaft 55 will push the crank arm 51, causing the crank arm 51 to rotate on the side wall of the spectrum analyzer body 1. While the crank arm 51 is rotating, it will drive the support rod 52 to swing downward. When the support rod 52 swings to the bottom of the spectrum analyzer body 1, the support rod 52 and the crank arm 51 can support the spectrum analyzer body 1, allowing the display screen 3 of the spectrum analyzer body 1 to tilt upward. This allows the operator to simply look down to observe the display screen 3, making it convenient for the operator to operate the spectrum analyzer body 1.

[0035] When the spectrum analyzer body 1 needs to be carried, firstly, rotate the threaded rod 58 by the handle 59. The rotation of the threaded rod 58, in conjunction with the threaded sleeve 56 connected to it, causes the bent rod 54 to slide on the side wall of the spectrum analyzer body 1, and gradually moves the bent rod 54 away from the boss 57. At the same time, in conjunction with the fixed shaft 55 and the through groove 53, the crank arm 51 can be rotated on the outer wall of the spectrum analyzer body 1. Simultaneously, the crank arm 51 will cause the support rod 52 to swing upward, so that the support rod 52 can be moved to the center position directly above the spectrum analyzer body 1. At this time, the staff can lift the spectrum analyzer body 1 by holding the support rod 52, which makes it convenient for the staff to carry the spectrum analyzer body 1 for use in different work locations.

[0036] As the bent rod 54 slides along the side wall of the spectrum analyzer body 1 and gradually moves away from the boss 57, it will drive the ball head rod 63 to move synchronously. When the ball head rod 63 contacts the inclined surface of the L plate 62 during its movement, the ball head rod 63 will press against the inclined surface of the L plate 62, thereby causing the ball head rod 63 to press the L plate 62 upward. At this time, the L plate 62 will drive the baffle 61 to slide upward on the front of the spectrum analyzer body 1. By sliding the baffle 61 upward, the display screen 3 on the front of the spectrum analyzer body 1 can be blocked, thereby protecting the display screen 3 during the process of carrying the spectrum analyzer body 1 and preventing the display screen 3 from being damaged by impact during the transfer.

[0037] As the bent rod 54 gradually approaches the boss 57 and causes the ball head rod 63 to detach from the L plate 62, under the weight of the baffle 61 and the L plate 62, the baffle 61 will slide downward on the front of the spectrum analyzer body 1, thereby allowing the baffle 61 to detach from the display screen 3 on the front of the spectrum analyzer body 1 so that the staff can observe the display screen 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
