For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0024] Example 1

[0025] As the role of power amplifiers in wireless communication systems continues to increase, the requirements for them are also increasing, so the testing of power amplifiers is also very important. Today, the testing of power amplifiers is more commonly done through test fixtures, but with the advancement of technology and the differences in actual needs, the requirements for test fixtures are also increasing.

[0026] In the conventional technology, the test fixture for the power amplifier is fixed on different sides of the power amplifier by several separate fixtures, so as to achieve stable clamping. However, in this method, the fixtures need to be operated separately. In actual operation, it is very inconvenient for the staff to operate it, which reduces the work efficiency. In addition, when the first fixture clamps the power amplifier, the fixtures on other sides have not clamped the power amplifier yet. The first fixture will inevitably cause the power amplifier to move. One fixture cannot clamp the power amplifier. Therefore, in actual operation, if the test platform 1 is large, it is difficult for the staff to operate the fixtures on different sides at the same time, so that the staff needs to move the fixtures to clamp the power amplifier multiple times before the power amplifier can be fixed for subsequent testing.

[0027] Therefore, in order to solve the above problems, in this embodiment, the clamps located on different surfaces are integrated into one, and the gear 8 rolls on the first raceway 6 and the second raceway 7. At the same time, the clamps arranged opposite to each other are operated to approach the power amplifier, so as to achieve stable clamping and simple operation, which can make it easier for the operator to fix the power amplifier and improve the test work efficiency.

[0028] Specifically, Figure 1 , Figure 2 As shown, a power amplifier testing device with a clamp comprises a testing platform 1, the upper end surface of the testing platform 1 is provided with a slide rail 2, a first clamping plate 3 and a second clamping plate 4 are slidably connected to the slide rail 2, the first clamping plate 3 and the second clamping plate 4 are arranged opposite to each other, and the power amplifier is placed between the two clamping plates, the first clamping plate 3 is provided with a first raceway 6 extending toward the second clamping plate 4, the second clamping plate 4 is provided with a second raceway 7 extending in the extension direction of the first clamping plate 3, a gear 8 is meshed between the first raceway 6 and the second raceway 7, and the rolling direction of the gear 8 on the first raceway 6 is opposite to the rolling direction on the second raceway 7.

[0029] Preferably, support columns 5 are vertically arranged on both the first clamping plate 3 and the second clamping plate 4, the height of the support columns 5 on the first clamping plate 3 is greater than the height of the support columns 5 on the second clamping plate 4, and the support columns 5 on the first clamping plate 3 are provided with a first raceway 6 parallel to the central axis of the slide rail 2, and the support columns 5 on the second clamping plate 4 are provided with a second raceway 7 parallel to the first raceway 6. The support columns 5 and the first raceway 6 or the second raceway 7 form an L-shaped column, and the L-shaped column is inverted on the corresponding clamping plate, and the first raceway 6 is arranged parallel to the slide rail 2. If the first raceway 6 extends toward the right, the second raceway 7 will also extend toward the right, because the rolling direction of the gear 8 on the first raceway 6 is opposite to the rolling direction on the second raceway 7.

[0030] Preferably, the lower end surface of the first raceway 6 is provided with a plurality of external teeth A61 arranged at equal intervals in the horizontal direction, and the external teeth A mesh with the gear 8, and the upper end surface of the second raceway 7 is provided with a plurality of external teeth B71 arranged at equal intervals in the horizontal direction, and the external teeth B71 mesh with the gear 8. The purpose is to mesh the gear 8 between the first raceway 6 and the second raceway 7, so that it rolls on the first raceway 6 and the second raceway 7 in opposite directions, and the rolling direction of the gear 8 on the raceway drives the lower clamping plate to slide on the slide rail 2 in the rolling direction. Figure 2 As shown, when the gear 8 rotates clockwise, the direction of the gear 8 on the first raceway 6 faces right, and the direction of the gear 8 on the second raceway 7 faces left, and the two rolling directions are opposite, and the two rolling directions are facing each other. It can be seen that the first clamping plate 3 and the second clamping plate 4 will slide towards each other on the slide rail 2 due to the rolling direction, so that the first clamping plate 3 and the second clamping plate 4 are approached inward at the same time, and are used to clamp the power amplifier located between the first clamping plate 3 and the second clamping plate 4. The operation is simple and can make it more convenient for the staff to perform testing work.

In order to protect the gear 8, the height of the lower end surface of the head of the first raceway 6 can be lower than the height of the external tooth A61, and the height of the upper end surface of the tail of the second raceway 7 can be higher than the height of the external tooth B71; or grooves are provided on the lower end surface of the first raceway 6 and the upper end surface of the second raceway 7, and the external tooth A61 and the external tooth B71 are located in the grooves, and the depth of the grooves can be greater than the length of the external tooth A61, so that the external tooth A61 is located in the grooves, which is used to limit the rolling of the gear 8 and prevent the gear 8 from rolling out.

[0032] Preferably, the shape and size of the external toothed member A61 is the same as that of the external toothed member B71, and the shapes include regular triangles, oblique triangles, rectangles, etc. Specifically, in this embodiment, the shapes of the external toothed member A61 and the external toothed member B71 are both oblique triangles, the oblique triangles have arc-shaped inclined surfaces, the external toothed member A61 includes an arc-shaped inclined surface, the external toothed member B71 includes an arc-shaped inclined surface, and the arc-shaped inclined surface of the external toothed member A61 is arranged opposite to the arc-shaped inclined surface of the external toothed member B71. The purpose is to ensure that the gear 8 rolls under the meshing action of the first raceway 6 and the second raceway 7.

[0033] Preferably, a handle 9 is fixedly connected to the side of the gear 8, and the gear 8 rolls on the first raceway 6 and the second raceway 7 by rotating the handle 9, and the handle 9 is arranged perpendicular to the gear 8. The purpose is to facilitate the staff to perform clamping operation through the handle 9, and the gear 8 can be rotated clockwise or counterclockwise by rotating the handle 9 forward or backward.

[0034] Preferably, the slide rail 2 includes a slide groove 21 and a guide rod 22 in the slide groove 21, the guide rod 22 extends in the slide groove 21 along the extension direction of the slide groove 21, a slider 23 is sleeved on the guide rod 22, the upper end surface of the slider 23 is connected to the lower end surface of the splint, so that the splint slides on the guide rod 22.

[0035] Preferably, a rubber pad is provided on the side of the first clamping plate 3 facing the second clamping plate 4, and a rubber pad is provided on the side of the second clamping plate 4 facing the first clamping plate 3. The purpose is to protect the side of the power amplifier from being damaged by pressure during the clamping process, and to increase friction to prevent the power amplifier from moving randomly during the clamping process.

[0036] Preferably, the length of the first raceway 6 is greater than or equal to the length of the second raceway 7 , and the length of the first raceway 6 is greater than the length of the slide rail 2 , thereby ensuring that the clamping plate can clamp the power amplifier.

[0037] Specifically, in this embodiment, the slide rail 2 is divided into two slide rails 2 arranged opposite to each other, and the platform between the two slide rails 2 can be used to place the power amplifier. The two slide rails 2 are respectively provided with a first clamping plate 3 and a second clamping plate 4, and the first clamping plate 3 and the second clamping plate 4 are arranged opposite to each other.
