Description

Technical Field

[0001] The utility model belongs to the technical field of signal testing and relates to a balancing device of a simple standing wave table. Background Art

[0002] A standing wave meter is an instrument used to measure the properties of electromagnetic waves and transmission line characteristics. It can be used to understand the propagation of signals in transmission lines and detect reflection and interference phenomena in transmission lines. The existing standing wave meters are divided into pointer type and digital type. Since digital standing wave meters need to be replaced frequently, if the battery is dead during the detection process, the standing wave meter will be powered off, resulting in reduced detection efficiency. It is very inconvenient to replace the battery and reconnect the test. Therefore, most of the old masters still use pointer type standing wave meters. However, the existing pointer type standing wave meters have the following shortcomings:

[0003] During use, the operator needs to adjust the initial position of the pointer in the standing wave meter. Since the operator's hands cannot be guaranteed not to shake, the standing wave meter must be placed on a stable horizontal surface for detection to avoid shaking that causes the pointer to shake and affect the detection effect. However, since the pointer itself has a certain weight, even if the standing wave meter can be placed on a tilted ground, the pointer will shift due to its own weight, resulting in a deviation in the detection effect. Utility Model Content

[0004] The utility model aims to solve the technical problem mentioned in the background technology that the existing pointer-type standing wave meter cannot be applied to inclined planes, resulting in reduced detection effect, by proposing a balancing device for a simple standing wave meter in view of the deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A balancing device for a simple standing wave table, comprising:

[0007] An installation frame, wherein the installation frame has two symmetrically arranged arc-shaped notches, and the installation frame has two symmetrically arranged arc-shaped sliding grooves respectively connected to the two arc-shaped notches;

[0008] A balancing frame, wherein the balancing frame is slidably disposed in the mounting frame;

[0009] Two sets of sliding groups, the two sets of sliding groups are symmetrically arranged at the lower end of the balance frame, and the two sets of sliding groups are respectively embedded in two corresponding arc-shaped sliding grooves;

[0010] An adjusting cylinder, wherein the fixed end of the adjusting cylinder is rotatably connected to the mounting frame, and the telescopic end of the adjusting cylinder is rotatably connected to the balancing frame;

[0011] Two clamping plates, the two clamping plates are slidably mounted on the top of the balancing frame and are symmetrically arranged;

[0012] The standing wave meter body is embedded between the two clamping plates.

[0013] Working principle:

[0014] First, embed the standing wave meter body between two telescopic clamping plates;

[0015] When the installation frame is placed on an inclined plane: start the adjusting cylinder to drive the telescopic rod to extend and retract, and the telescopic rod drives the balance frame to move forward or backward along the arc-shaped slide groove, so that the top of the balance frame is kept at a balanced horizontal plane, so that the standing wave meter body is in a balanced state, and then the standing wave meter body can be adjusted.

[0016] The beneficial effects of the utility model are:

[0017] The utility model can effectively adjust the placement state of the standing wave meter body by arranging the installation frame, the balance frame and the adjustment cylinder, so that the standing wave meter body can be kept in a horizontal state, avoiding the standing wave meter body from tilting, thereby improving the subsequent detection quality. The utility model can be effectively applied to inclined planes, has good practicality and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1-3 As shown, a balancing device of a simple standing wave table comprises:

[0027] An installation frame 1, wherein the installation frame 1 has two symmetrically arranged arc-shaped notches 2, and the installation frame 1 has two symmetrically arranged arc-shaped sliding grooves 3 respectively connected to the two arc-shaped notches 2;

[0028] A balancing frame 4, wherein the balancing frame 4 is slidably disposed in the mounting frame 1;

[0029] Two sets of sliding groups, the two sets of sliding groups are symmetrically arranged at the lower end of the balance frame 4, and the two sets of sliding groups are respectively embedded in two corresponding arc-shaped sliding grooves 3;

[0030] An adjusting cylinder 5, wherein the fixed end of the adjusting cylinder 5 is rotatably connected to the mounting frame 1, and the telescopic end of the adjusting cylinder 5 is rotatably connected to the balancing frame 4;

[0031] Two clamping plates 6, the two clamping plates 6 are slidably mounted on the top of the balancing frame 4 and are symmetrically arranged;

[0032] The standing wave meter body 7 is embedded between the two clamping plates 6 .

[0033] like Figure 6 As shown, the installation frame 1 includes two placement plates 8, two symmetrically arranged connecting rods 9 are fixed between the two placement plates 8, and the two arc-shaped notches 2 are respectively opened at the upper ends of the two placement plates 8.

[0034] like Figure 3 and Figure 5 As shown, the balance frame 4 includes a mounting plate 10 and four support rods 11, the four support rods 11 are rectangular and fixed at the lower end of the mounting plate 10, the sliding group includes two sliders 12, the four sliders 12 correspond to the four support rods 11 one by one and are respectively fixed at the lower ends of the four support rods 11, each of the arc-shaped slide grooves 3 is embedded with two sliders 12, the sliders 12 can slide along the arc-shaped slide grooves 3, and symmetrically arranged guide columns 13 are fixed at both ends of each slider 12, and the inner side walls of the arc-shaped slide grooves 3 are provided with limiting grooves 14 for embedding two guide columns 13, and the telescopic guide columns 13 can move along the limiting grooves 14.

[0035] like Figure 2 and Figure 4As shown, an adjusting block 15 is fixed to the fixed end of the adjusting cylinder 5, and the adjusting block 15 has a round hole for the connecting rod 9 to pass through. A rotating block 16 is fixed to the telescopic end of the adjusting cylinder 5. A connecting frame 17 is fixed to the lower end of the mounting plate 10, and a connecting shaft 18 is fixed inside the connecting frame 17. The rotating block 16 has a rotating hole for the connecting shaft 18 to pass through.

[0036] like Figure 2 and Figure 6 As shown, the two clamping plates 6 have guide blocks 19 at the bottom, and the mounting plate 10 has a guide groove 20 at the top. The two guide blocks 19 are embedded in the guide groove 20 and are symmetrically arranged. A partition plate 21 is fixed to the inner wall of the guide groove 20. Springs 22 are fixed to the inner sides of the two guide blocks 19 and to both ends of the partition plate 21. By pulling the two clamping plates 6 at the same time and moving them relatively away from each other, the clamping plates 6 drive the guide blocks 19 to move along the guide groove 20. The guide blocks 19 stretch the springs 22. The springs 22 have a certain elastic potential energy under stretching. Then, the standing wave table body 7 is placed between the two clamping plates 6, and the clamping plates 6 are released.
