Description

Technical Field

[0001] The utility model relates to the technical field of broadband active array antenna test tooling, and specifically relates to a test tooling with adjustable angle under polarization state. Background Technique

[0002] Antenna polarization test refers to testing the polarization direction of an antenna to determine the operating state and performance of the antenna. When conducting an antenna polarization test, equipment such as an antenna test instrument or an antenna analyzer is usually used. By measuring the received and transmitted signals of the antenna, it is determined whether its polarization direction (such as horizontal polarization, vertical polarization, etc.) is correct, and parameters such as the gain and beam width of the antenna are evaluated. Therefore, a test tooling is required to fix the antenna on the turntable.

[0003] When the existing antenna test tooling is in use, since the antenna test usually requires test tooling requirements in the vertical state and the horizontal state, and the existing test tooling can only meet one test state, it is necessary to prepare two toolings to meet the use, and the operation is cumbersome and troublesome. Summary of the Invention

[0004] The purpose of the utility model is to provide a test tooling with adjustable angle under polarization state to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A test tooling with adjustable angle under polarization state, the test tooling arranged on the turntable is used for installing and fixing the antenna, including:

[0007] A connection bracket, the connection bracket includes a middle transfer bracket arranged on the turntable, a left support plate and a right support plate symmetrically arranged on the middle transfer bracket, and a rotatable shaft seat arranged between the left support plate and the right support plate; and

[0008] A rotary mounting seat, the rotary mounting seat includes a transfer bracket bottom plate arranged on the rotatable shaft seat, an upper transfer bracket and a lower transfer bracket symmetrically arranged on both sides of the transfer bracket bottom plate, and a transfer base arranged between the upper transfer bracket and the lower transfer bracket. The transfer base is used for installing the antenna. By removing the transfer bracket bottom plate from the rotatable shaft seat, rotating it and reinstalling it, the antenna can be switched between the vertical state and the horizontal state.

[0009] Preferably, a top transfer plate for enhancing the structural strength is further arranged between the left support plate and the right support plate.

[0010] Preferably, the transfer bracket, left support plate, right support plate, rotatable axle seat, transfer bracket bottom plate, upper transfer bracket, lower transfer bracket, transfer base, and top transfer plate are all made of ABS material.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model includes a connection bracket and a rotary mounting seat. The rotary mounting seat includes a transfer bracket bottom plate arranged on a rotatable axle seat and a transfer base arranged between an upper transfer bracket and a lower transfer bracket. The present utility model fixes and connects an antenna through the transfer base and cooperates with the transfer bracket bottom plate. After rotating the transfer bracket bottom plate and reconnecting it to the rotatable axle seat, a tooling can meet the testing tooling requirements in both vertical and horizontal states. At the same time, because non-metallic materials are used and the left support plate and the right support plate have a certain height and are far from the turntable, the interference with electromagnetic waves is very small. The present utility model is simple to operate and will be more convenient in the conversion and assembly process. Description of the Drawings
