Description

Technical Field

[0001] This utility model relates to the field of standing wave detection technology, specifically to an online detection device based on standing wave monitoring and control. Background Technology

[0002] The standing wave ratio (SWR) of an antenna system has a significant impact on transmission efficiency. An excessively high SWR will result in a large amount of power being reflected, causing round-trip transmission in the feed line, resulting in additional losses, abnormal voltages, or abnormal currents, which can prevent the transmitter from functioning properly or even damage it. Therefore, it is necessary to test the SWR. A standing wave tester can measure return loss or SWR, which allows us to quickly assess the condition of the transmission line and antenna system. Through specific sensors and signal processing technology, the standing wave tester can monitor various parameters of the standing wave in real time, such as SWR, return loss, and frequency.

The handheld component includes a slide base slidably connected to the VSWR tester body and a slider slidably connected to the slide base. The VSWR tester body has locking slots on both sides. A first fixing component is provided between the slide base and the VSWR tester body. A second fixing strap is provided on one side of the slide base, and a first fixing strap connected to the second fixing strap is provided on one side of the slider. This design facilitates one-handed grip and allows the position of the handheld component to be adjusted as needed, allowing the user to hold it with either their left or right hand to meet different needs.

[0004] While the aforementioned patents facilitate the use of the testing instrument, some problems remain. During use, the testing instrument is often placed on a table for easy viewing and control by staff. Therefore, it is necessary to ensure the stability of the testing instrument on the table to prevent it from tipping over and affecting its performance. To address this, this utility model provides an online testing device based on standing wave monitoring and control. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides an online detection device based on standing wave monitoring and control. Compared with the prior art, it has the following advantages:

[0016] 1. This online detection device based on standing wave monitoring and control allows for monitoring and control of standing waves when the instrument body is placed on a table. First, the support base is placed on the table, then the instrument body is rotated to a suitable angle for easy viewing. The threaded sleeve and threaded rod are then removed from their placement slots, and the threaded sleeve is rotated to extend and retract to a suitable distance on the threaded rod. Rotating the threaded sleeve then moves the rubber support block onto the anti-slip groove surface of the support plate, providing support for the instrument body. Because the support base has a rubber anti-slip pad on its bottom surface and a large contact area with the table, the stability of the instrument body on the table is increased, preventing tipping due to instability. This facilitates normal viewing and control of the instrument body by staff, avoiding any impact on performance due to tipping. Furthermore, the cooperation of the threaded sleeve and threaded rod allows for support of the instrument body at different tilt angles, thereby changing the tilt angle on the table to achieve the optimal viewing and operating angle, improving ease of use and comfort.

[0017] 2. When the online testing device based on standing wave monitoring and control needs to be used by hand, the pull rod is first pulled by the pull plate to move the insert block away from the tester body. Then, the tester body is rotated so that it fits against the surface of the support base plate. At this time, the locking housing is aligned with the insert block. Then, the pull plate is released, and the insert block is pushed into the locking housing under the action of the spring force, so that the support base plate and the tester body are fixedly connected. At this time, the tester body can be moved by hand by the handle, which makes it convenient to use the tester body by hand. Attached Figure Description

[0025] 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.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: an online detection device based on standing wave monitoring and control, including a support base plate 1, a mounting frame 2 fixedly installed on the top of the support base plate 1, a tester body 4 provided on the inner wall of the mounting frame 2, a support component 6 provided on the top of the support base plate 1, and a fixing component 8 provided on one side of the outer wall of the support base plate 1.

[0028] The support assembly 6 includes a support plate 65. The outer wall of the support plate 65 is provided with an anti-slip groove 66. The top of the support base plate 1 is provided with a placement groove 61. A rotating block 62 is rotatably installed on the inner wall of the placement groove 61. A threaded rod 63 is fixedly installed on one end of the outer wall of the rotating block 62. A threaded sleeve 64 is threadedly connected to the outer wall of the threaded rod 63. The threaded rod 63 and the threaded sleeve 64 can rotate along the rotating block 62. Rotating the threaded sleeve 64 allows the threaded sleeve 64 to move on the threaded rod 63, thereby adjusting the length between the threaded rod 63 and the threaded sleeve 64, which facilitates the support of the tester body 4.

[0029] The fixing component 8 includes a snap-fit ​​fixing shell 86 and an L-shaped plate 81. An insert 85 is provided on one side of the outer wall of the L-shaped plate 81. The insert 85 matches the inner wall of the snap-fit ​​fixing shell 86. The insert 85 can be inserted into the snap-fit ​​fixing shell 86 to fix the tester body 4 to the support base plate 1.

[0030] The inner wall of the mounting bracket 2 is equipped with a rotating rod 3, and the outer wall of the rotating rod 3 is fixedly fitted with a connecting block 5. The outer wall of the connecting block 5 is fixedly connected to the tester body 4, which allows the tester body 4 to rotate on the support base plate 1. The support plate 65 is fixedly connected to the bottom end of the tester body 4.

[0031] Two square grooves 67 are provided at the top of the support base plate 1. The two square grooves 67 are connected to the placement groove 61, which makes it convenient for personnel to remove the threaded tube sleeve 64 from the placement groove 61. A rubber support block 68 is fixedly installed on one end of the outer wall of the threaded tube sleeve 64. The rubber support block 68 can support the anti-slip groove 66 and improve the friction between the two. By changing the extension length of the rubber support block 68 on the threaded tube sleeve 64 and the angle of the threaded tube sleeve 64, the tester body 4 at different tilt angles can be supported.

[0032] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that the snap-fit ​​fixing shell 86 is fixedly connected to one side of the outer wall of the tester body 4, the L-shaped plate 81 is fixedly connected to one side of the outer wall of the support base plate 1, and two pull rods 82 slide through the outer wall of the L-shaped plate 81. The output ends of the two pull rods 82 are fixedly connected to the insert block 85, and the pull rods 82 can drive the insert block 85 to move.

[0033] Springs 84 are fitted on the outer walls of both pull rods 82. One end of each spring 84 is fixedly connected to the insert block 85, and the other end of each spring 84 is fixedly connected to the L-shaped plate 81. Pull plates 83 are fixedly installed on one end of the outer walls of both pull rods 82. Under the action of the spring force of the spring 84, the insert block 85 can be pushed into the snap-fit ​​fixing shell 86.

[0034] Handles 7 are fixedly installed on both sides of the outer wall of the tester body 4. The handles 7 facilitate the movement of the tester body 4. A rubber anti-slip pad 9 is fixedly installed at the bottom of the support base plate 1. The rubber anti-slip pad 9 improves the friction between the device and the table.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] When monitoring and controlling the standing wave by placing the tester body 4 on a table during operation, first place the support base plate 1 on the table, then rotate the tester body 4 to a suitable angle for easy viewing and monitoring. At this point, remove the threaded sleeve 64 and threaded rod 63 from the placement slot 61, then rotate the threaded sleeve 64 to extend and retract it to a suitable distance on the threaded rod 63. Rotating the threaded sleeve 64 then moves the rubber support block 68 onto the anti-slip groove 66 surface on the support plate 65, thus supporting the tester body 4. Because the bottom surface of the support base plate 1 is equipped with a rubber anti-slip pad 9, and the contact area between the support base plate 1 and the table is large, the stability of the tester body 4 on the table is increased, preventing it from tipping over due to instability. This facilitates normal viewing and control of the tester body 4 by the staff, avoiding situations such as tipping over. The screw thread sleeve 64 and screw thread rod 63 work together to support the tester body 4 at different tilt angles, thereby changing the tilt angle of the tester body 4 on the table to achieve the best viewing and operating angle, improving the convenience and comfort of use. When the tester body 4 needs to be used by hand, first pull the lever 82 through the pull plate 83 to move the insert block 85 away from the tester body 4. Then rotate the tester body 4 so that the tester body 4 is in contact with the surface of the support base plate 1. At this time, the locking and fixing shell 86 is aligned with the insert block 85. Then release the pull plate 83. At this time, the insert block 85 is pushed into the locking and fixing shell 86 under the action of the spring force of the spring 84, so that the support base plate 1 and the tester body 4 are fixedly connected. At this time, the tester body 4 can be moved by hand through the handle 7, which makes it convenient to use the tester body 4 by hand.
