Description

Technical Field

[0001] This invention relates to the field of spectrum analyzer technology, specifically to a spectrum analyzer for radio frequency power supply repair. Background Technology

[0002] A spectrum analyzer used in radio frequency (RF) power supply repair is an electronic measuring instrument specifically designed to measure and analyze the energy distribution of radio frequency (RF) signals in the frequency domain. Its core function is to diagnose and analyze the output signal of the RF power supply during repair. It can convert the complex time-domain signal output by the RF power supply into a frequency-domain signal and intuitively display the amplitude of each frequency component in the signal in the form of a spectrum diagram. This allows repair personnel to clearly see key parameters such as carrier frequency, harmonics, spurious emissions, and noise floor. By analyzing the spectrum diagram, repair personnel can identify common fault signs of the RF power supply.

[0003] Application CN119575229A discloses a radio frequency power supply testing device and testing method. The protective cover rotates on the front end face of the testing body; the pressing suction cup is fixedly connected to the lower end face of the testing body; the carrying and protective mechanism is set inside the testing body; and the placement and stabilizing mechanism is set inside the testing body. By adopting the carrying and protective mechanism, it is convenient for staff to use the testing device. By adopting the placement and stabilizing mechanism, the stability of the testing device on the table is ensured, solving the problem that the spectrum analyzer is affected by bumps and knocks.

[0004] Application CN208367088U discloses a spectrum analyzer. A start button is located on one outer surface of the main body of the spectrum analyzer near the bottom of the button, and an emergency stop button is located next to the start button. A voice player is located on one outer surface of the main body of the spectrum analyzer near the bottom, and a handle is fixedly installed on one outer surface of the main body of the spectrum analyzer near the top of the voice player. The handle, drop protection pad, and voice player allow for better carrying of the spectrum analyzer to the workplace, prevent damage from drops, and effectively analyze equipment problems.

[0005] However, the spectrum analyzers disclosed above for RF power analysis still have the following problems in actual use: protective components installed on the outside of the spectrum analyzer are used to cover and protect the spectrum analyzer during maintenance operations. However, these protective components are mostly separate or integrated. Integrated protective components cover the outside of the spectrum analyzer, but have low adaptability and need to be specially molded and manufactured for different specifications of spectrum analyzers. Separate protective components cannot effectively connect the spectrum analyzer, thus still affecting the protection effect of the spectrum analyzer during use.

[0006] Therefore, we propose a spectrum analyzer for RF power supply repair to address the aforementioned problems. Summary of the Invention

[0007] The purpose of this invention is to provide a spectrum analyzer for radio frequency power supply repair. This invention addresses the problem that existing protective components installed on the outside of the spectrum analyzer provide coverage protection during repair work. However, these protective components are mostly either separate or integrated. Integrated protective components cover the outside of the spectrum analyzer but have low adaptability, requiring special mold manufacturing for different specifications of spectrum analyzers. Separate protective components cannot effectively connect to the spectrum analyzer, thus still affecting the protection effect of the spectrum analyzer during use.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a spectrum analyzer for radio frequency power supply repair, comprising an analyzer body for radio frequency power supply repair, wherein a power interface is provided on the back of the analyzer body and a spectrum display screen is provided on the front of the analyzer body, thereby enabling radio frequency power supply repair operations. The analyzer body is provided with a protective mechanism, which includes a protective housing and a protective top cover at the top of the protective housing. The protective mechanism includes a positioning shaft, which is rotatably mounted on the lower end of the analyzer body via a bearing, and the positioning shaft and the analyzer body are connected to each other by a torsion spring. The protective housing is equipped with a linkage mechanism, which includes a transmission shaft. The left and right ends of the transmission shaft are connected to the rear end of the guide screw through a bevel gear set.

[0009] Preferably, the protective mechanism includes a protective groove, which is located inside the protective housing. Guide grooves are provided on both the left and right sides at the rear of the protective housing, and guide rods are fixedly installed inside the guide grooves.

[0010] Preferably, the protective housing included in the protective mechanism is used to install the analyzer body through the internal protective groove. In the initial state, the analyzer body inside the protective housing is distributed horizontally with the spectrum display screen facing downwards, and the outer end of the positioning shaft at the bottom of the analyzer body is slidably installed inside the guide groove.

[0011] Preferably, the outer end of the positioning rotating shaft included in the protective mechanism is slidably sleeved on the outside of the guide slide rod, and the front end of the guide slide rod and the positioning rotating shaft are connected to each other by a return spring. The positioning rotating shaft drives the analyzer body to slide forward along the guide slide rod, and the torsion spring drives the analyzer body to flip upward so that the spectrum display screen is tilted in front.

[0012] Preferably, the protective mechanism includes a protective top cover whose rear end is fixedly connected to a flip bracket, and the lower end of the flip bracket is fixedly connected to the middle of the transmission shaft. The outer end of the transmission shaft is rotatably mounted on the upper part of the rear outer wall of the protective box through a bearing. Furthermore, a closable power supply slot is provided at the rear of the protective box, through which the power cord is connected to the power interface on the back of the analyzer body.

[0013] Preferably, the linkage mechanism includes an unlocking slide groove, which is located on the left and right sides of the upper part of the protective box. The interior of the unlocking slide groove is rotatably connected to the front end of the guide screw via a bearing, and the inner end of the unlocking slide groove communicates with the protective groove inside the protective box.

[0014] Preferably, the linkage mechanism includes a sliding brush plate, which is slidably installed inside the lower part of the protective groove, and the top surface of the sliding brush plate is attached to the spectrum display screen on the bottom surface of the analyzer body, and the left and right ends of the outer end of the sliding brush plate are fixedly connected to the lower end of the transmission brush plate.

[0015] Preferably, the linkage mechanism includes transmission brushes distributed in an inverted "L" shape, with the upper ends of the left and right transmission brushes slidably installed inside the protective groove inside the protective housing, and heat dissipation brush blocks fixedly installed on the upper inner walls of the left and right transmission brushes, and the heat dissipation brush blocks sliding against the heat dissipation slots on the left and right sides of the analyzer body.

[0016] Preferably, the upper end of the transmission brush plate included in the linkage mechanism is threadedly connected to the front outer wall of the guide screw, and the maximum sliding length of the transmission brush plate is greater than the length of the analyzer body from back to front. Furthermore, a limit contact plate is fixedly installed at the upper end of the transmission brush plate, and the upper end of the limit contact plate slides against the upper surface of the transverse state analyzer body.

[0017] Preferably, the analyzer body included in the linkage mechanism is limited by the limiting contact plate at the upper end of the transmission brush plate. The transmission brush plate drives the sliding brush plate and the heat dissipation brush block to slide from back to front, cleaning the spectrum display screen and heat dissipation slots of the analyzer body in the horizontal state. After the limiting contact plate is moved to the front of the analyzer body, the analyzer body is flipped upward to perform maintenance work.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The spectrum analyzer for RF power supply repair is protected by a protective housing. Before operation, the analyzer body is cleaned and unlocked by a sliding brush and a limiting contact plate, thereby allowing the analyzer body to flip into a vertically tilted state. The tilted state facilitates observation of the spectrum display screen and connection to the power interface, improving the ergonomic comfort and efficiency of the repair operation. The specific details are as follows: 1. The protective top cover is fixedly connected to the upper part of the protective box via a flip bracket. When closed, it forms a sealed space, effectively isolating dust, moisture and physical impact. The size of the protective slot is precisely matched to the outline of the analyzer body, ensuring that the equipment is stably fixed during transportation or when idle, and avoiding shaking that could damage the internal precision components. The power supply slot at the rear of the protective box is designed to be enclosed, allowing the power cord to be connected to the power interface on the back of the analyzer body when the equipment is in use, while maintaining the overall protective integrity of the box.

[0019] 2. The flip bracket is connected to the rear end of the protective top cover. When opened, it drives the transmission shaft to rotate. The transmission shaft drives the left and right guide screws to rotate through the meshing of the bevel gear group, so that the threaded transmission brush plate slides forward along the unlocking slide groove. The upper end of the transmission brush plate is fixed with a limit contact plate, which releases the lock on the analyzer body when it moves.

[0020] Furthermore, the transmission brush plate drives the inner sliding brush plate and the heat dissipation brush block to move forward synchronously. The sliding brush plate adheres to the surface of the spectrum display screen to remove accumulated dust, and the heat dissipation brush block penetrates into the heat dissipation slots on the side of the analyzer body to clean the dirt. The cleaning operation is only performed when the analyzer body is in a horizontal position.

[0021] 3. The sliding brush plate is installed at the bottom of the protective slot, and its top surface is in close contact with the spectrum display screen at the bottom of the analyzer body. When the drive brush plate moves, the sliding brush plate slides along the surface of the spectrum display screen, and physical friction removes oil and dust to ensure display clarity. The heat dissipation brush block is fixed to the inner wall of the drive brush plate and is inserted into the heat dissipation slots on both sides of the analyzer body to scrape off internal dirt and maintain heat dissipation efficiency.

[0022] 4. The lower end of the analyzer body is connected to the positioning shaft via a torsion spring. After unlocking, the torsion spring releases stress and drives the analyzer body to flip upward. The outer end of the positioning shaft is slidably sleeved on the outside of the guide slide rod. The guide slide rod is fixed in the guide groove. The front end is buffered by a reset spring. During the flipping process, the analyzer body moves forward along the guide slide rod and tilts to position itself, so that the spectrum display screen is at an angle facing the user.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problems existing in the use of the existing spectrum analyzer body 1, this example discloses the following technical solution: a spectrum analyzer for RF power supply repair, comprising an analyzer body 1 for RF power supply repair, the analyzer body 1 having an external protective mechanism, the protective mechanism including a protective housing 4, and a protective top cover 5 at the upper end of the protective housing 4; a linkage mechanism being provided inside the protective housing 4, the linkage mechanism including a transmission shaft 8, and the left and right ends of the transmission shaft 8 being meshed with the rear end of the guide screw 10 through a bevel gear set 9; a flip bracket 15 being fixedly connected to the rear end of the protective top cover 5 included in the protective mechanism, the lower end of the flip bracket 15 being fixedly connected to the middle of the transmission shaft 8, and the outer end of the transmission shaft 8 being rotatably mounted on the upper part of the rear outer wall of the protective housing 4 through a bearing.

[0027] The linkage mechanism includes an unlocking slide 17, which is located on the left and right sides of the upper part of the protective housing 4. The interior of the unlocking slide 17 is rotatably connected to the front end of the guide screw 10 via a bearing. The inner end of the unlocking slide 17 is in communication with the protective groove 11 inside the protective housing 4. The upper end of the transmission brush plate 19 included in the linkage mechanism is threadedly connected to the outer wall of the front end of the guide screw 10. The maximum sliding length of the transmission brush plate 19 is greater than the length of the analyzer body 1 from back to front.

[0028] like Figures 7-8 As shown, when the analyzer body 1 is needed to perform maintenance work on the RF power supply, the protective top cover 5 on the top of the protective housing 4 is unlocked, causing the flip-top protective top cover 5 to rotate upwards. This allows the protective top cover 5 to drive the flip-top bracket 15 and the transmission shaft 8, which are fixedly connected at the rear end, to rotate. During the rotation, the transmission shaft 8 drives the guide screw 10, which is meshed with the bevel gear group 9 on the left and right sides, to rotate. Then, the transmission brush plate 19, which is threadedly connected to the guide screw 10, is limited by the unlocking groove 17. This allows the rotating guide screw 10 to drive the threaded transmission brush plate 19 to slide from back to front. The transmission brush plate 19 then drives the upper fixedly connected limit contact plate 21 to slide on the top surface of the analyzer body 1. After moving to the front of the protective groove 11, it separates from the analyzer body 1, thereby unlocking the analyzer body 1 and allowing it to rotate during subsequent maintenance of the RF power supply.

[0029] Example 2: To solve the problems existing in the use of the existing spectrum analyzer body 1, this example discloses the following technical solution: The linkage mechanism includes a sliding brush plate 18, which is slidably installed inside the lower part of the protective groove 11. The top surface of the sliding brush plate 18 is attached to the spectrum display screen 3 on the bottom surface of the analyzer body 1, and the left and right ends of the outer end of the sliding brush plate 18 are fixedly connected to the lower end of the transmission brush plate 19. The transmission brush plate 19 included in the linkage mechanism is distributed in an inverted "L" shape. The upper ends of the left and right transmission brush plates 19 are slidably installed inside the protective groove 11 inside the protective housing 4. Heat dissipation brush blocks 20 are fixedly installed on the upper part of the inner wall of the left and right transmission brush plates 19, and the heat dissipation brush blocks 20 are attached to and slidably installed in the heat dissipation slots on the left and right sides of the analyzer body 1.

[0030] A limiting contact plate 21 is fixedly installed on the upper end of the transmission brush plate 19, and the upper end of the limiting contact plate 21 slides against the upper surface of the transverse state analyzer body 1. The analyzer body 1 included in the linkage mechanism is limited by the limiting contact plate 21 at the upper end of the transmission brush plate 19. The transmission brush plate 19 drives the sliding brush plate 18 and the heat dissipation brush block 20 to slide from back to front, cleaning the spectrum display screen 3 and heat dissipation slots of the transverse state analyzer body 1. After the limiting contact plate 21 is moved to the front of the analyzer body 1, the analyzer body 1 is flipped upward to perform maintenance work.

[0031] like Figures 4-5 , Figures 9-10 As shown, when the transmission brush plate 19 slides from back to front, it drives the heat dissipation brush block 20 fixedly connected to the inner side to move synchronously with the sliding brush plate 18, so that the inner wall of the heat dissipation brush block 20 slides against the heat dissipation slots on the left and right sides of the analyzer body 1. At the same time, the sliding brush plate 18 adheres to the spectrum display screen 3 on the bottom surface of the analyzer body 1 to clean the spectrum display screen 3 and improve the performance of the analyzer body 1.

[0032] Example 3: To address the problems existing in the use of the existing spectrum analyzer body 1, this example discloses the following technical solution: A power interface 2 is provided on the back of the analyzer body 1, and a spectrum display screen 3 is provided on the front of the analyzer body 1 to enable maintenance of the RF power supply; A closable power supply transverse groove 16 is provided at the rear of the protective housing 4, through which the power cord is connected to the power interface 2 on the back of the analyzer body 1; The protective mechanism includes a positioning shaft 6, which is rotatably mounted on the lower end of the analyzer body 1 via a bearing, and the positioning shaft 6 and the analyzer body 1 are connected to each other via a torsion spring 7; The protective mechanism includes a protective groove 11, which is opened inside the protective housing 4, and guide grooves 12 are provided on both the left and right sides at the rear of the protective housing 4, and guide rods 13 are fixedly installed inside the guide grooves 12.

[0033] The protective housing 4 of the protective mechanism is used to install the analyzer body 1 through the internal protective groove 11. In the initial state, the analyzer body 1 inside the protective housing 4 is distributed horizontally with the spectrum display screen 3 facing downwards, and the outer end of the positioning shaft 6 at the bottom of the analyzer body 1 is slidably installed inside the guide groove 12. The outer end of the positioning shaft 6 of the protective mechanism is slidably sleeved on the outside of the guide slide rod 13, and the front end of the guide slide rod 13 and the positioning shaft 6 are connected to each other through the return spring 14. The positioning shaft 6 drives the analyzer body 1 to slide forward along the guide slide rod 13, and the torsion spring 7 drives the analyzer body 1 to flip upwards so that the spectrum display screen 3 is tilted in front.

[0034] like Figures 1-3As shown, after the analyzer body 1 inside the protective housing 4 separates from the limiting contact plate 21, its lower end is connected to the positioning shaft 6 via the torsion spring 7 to release stress, thereby causing the analyzer body 1 to flip upward, so that the analyzer body 1 flips from a horizontal state to a vertical tilted state. At the same time, the analyzer body 1 abuts against the rear end of the protective housing 4 and squeezes its lower end, causing the positioning shaft 6 to slide forward along the guide slide rod 13, so that the analyzer body 1 is tilted with the upper end facing backward and the lower end facing forward, which facilitates spectrum display and power supply maintenance through the spectrum display screen 3.

[0035] Furthermore, the analyzer body 1 is arranged in a vertically inclined state inside the protective housing 4. By opening the power supply slot 16 at the rear of the protective housing 4, the power cord can be installed from the opened power supply slot 16 into the interior of the protective housing 4 and connected to the power interface 2 on the back of the analyzer body 1, so as to enable the analyzer body 1 to perform radio frequency power analysis and maintenance.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
