However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0025] Unless otherwise specified or stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “a,” “an,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “comprising” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to those listed; the terms “first” and “second” are used only as illustrative marks and are not intended to limit the number, importance, or order of the objects.

[0026] The terms “connection” and “fixation” should be interpreted broadly. For example, “connection” can be a fixed connection, a movable connection, an integral connection, or a detachable connection. It can be a direct connection or an indirect connection through an intermediate medium.

[0027] The phrase "part A is located on part B" as described in this disclosure can mean that part A is directly connected to part B, or that part A is located on part C, and part C is located on part B.

[0028] Furthermore, in this application, directional terms such as "upper" and "lower" are used only to indicate relative positional relationships. For example, for convenience, they are defined based on the actual position and state of the test fixture during operation, or relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts and can change accordingly depending on the orientation of the components in the accompanying drawings. Exemplarily, in the description of this disclosure, reference is made to... Figure 1 As shown, the direction of the base plate 1 is "down" and the direction of the mounting platform 51 is "up". The first direction is the direction perpendicular to the base plate 1.

[0029] During the testing of cylindrical antennas, it is necessary to change the elevation angle of the antenna. Existing testing fixtures require manual disassembly and reassembly to change the attitude of the antenna under test, which is laborious, requires multiple people to work together, and increases the operation time.

[0030] To address the aforementioned problems, this disclosure provides a test fixture for an antenna, with reference to... Figure 1 As shown, it includes: a base plate 1, a heightening part 2, a first fixing plate 3, a rotating plate 4, and a turntable 5. The heightening part 2 is disposed between the base plate 1 and the first fixing plate 3 along a first direction; the rotating plate 4 is disposed on the side of the first fixing plate 3 away from the heightening part 2, and the rotating plate 4 and the first fixing plate 3 are rotatably connected by an axis along a second direction, which is perpendicular to the first direction; the turntable 5 is disposed on the side of the rotating plate 4 away from the first fixing plate 3, and the turntable 5 is rotatably disposed relative to the rotating plate 4 about an axis perpendicular to the rotating plate 4, and the top of the turntable 5 has a mounting platform 51 for mounting an antenna.

[0031] The antenna testing fixture disclosed herein includes a mounting platform 51 on top of a turntable 5 for mounting the antenna. A rotating plate 4 is rotatably connected to a first fixed plate 3. The rotating plate 4 can be adjusted in elevation relative to the first fixed plate 3, causing the turntable 5 on it to change its elevation angle, which in turn causes the antenna on the mounting platform 51 to change its elevation angle. The continuous elevation rotation of the rotating plate 4 relative to the first fixed plate 3 allows for testing of the elevation angle of a cylindrical antenna without disassembling the antenna or the fixture, offering the advantage of convenient operation.

[0032] For example, refer to Figure 1As shown, the heightening section 2 may include multiple parallel first columns along a first direction. For example, the heightening section 2 may include four parallel first columns, each located at one of the four corners of the square base plate 1. In an exemplary embodiment of this disclosure, the height of the first column is not less than 1.5 meters, that is, the distance between the first fixing plate 3 and the base plate 1 is not less than 1.5 meters. For some models of cylindrical antennas, due to performance requirements, no metal materials are allowed within 1.5 meters of the test range. This exemplary embodiment can ensure that the distance between the cylindrical antenna under test installed on the mounting platform 51 and the base plate 1 is not less than 1.5 meters, making it less susceptible to the influence of metal materials from below and improving the accuracy of the test data. For example, the distance between the first fixing plate 3 and the base plate 1 is 1.5 meters; or, for example, the distance between the first fixing plate 3 and the base plate 1 is 2 meters, making the cylindrical antenna less susceptible to the influence of the external environment during the test.

[0033] In particular, in order to clearly demonstrate the overall structure of the test fixture disclosed herein, Figure 1 It is not drawn to scale.

[0034] In one exemplary embodiment of this disclosure, reference is made to Figures 1 to 3 As shown, where, Figure 2 , Figure 3 This is a partial view of the test fixture disclosed herein; incomplete structural sections are marked with double-dotted lines. The first fixed plate 3 includes a first end plate 31 and a first bracket 32, and the rotating plate 4 includes a second end plate 41 and a second bracket 42. The first bracket 32 ​​is located on the side of the first end plate 31 away from the raised portion 2, and the second bracket 42 is located on the side of the second end plate 41 away from the turntable 5. The first bracket 32 ​​and the second bracket 42 are rotatably connected by a first rotating shaft 6 along a second direction. Exemplarily, the second direction is a direction parallel to the base plate 1. When the base plate 1 is parallel to the horizontal plane, the second direction can be any direction within the horizontal plane; the base plate 1 and the first end plate 31 can be parallel, and the second end plate 41 and the mounting platform 51 can be parallel. The turntable 5 is rotatably disposed relative to the rotating plate 4 about an axis perpendicular to the rotating plate 4. Specifically, the turntable 5 can be rotatably disposed relative to the second end plate 41 about an axis perpendicular to the second end plate 41.

[0035] In one exemplary embodiment of this disclosure, reference is made to Figure 3As shown, the first rotating shaft 6 passes through the first bracket 32 ​​and the second bracket 42 to achieve a rotatable connection between the first bracket 32 ​​and the second bracket 42. Exemplarily, the first rotating shaft 6 has a first limiting part 61 at the end of the second bracket 42 away from the first bracket 32, and a limiting nut 62 is fitted onto the end of the first rotating shaft 6 at the end of the first bracket 32 ​​away from the second bracket 42. The first limiting part 61 can prevent the first rotating shaft 6 from disengaging towards the first bracket 32, and the limiting nut 62 can prevent the first rotating shaft 6 from disengaging towards the second bracket 42. Specifically, the first rotating shaft 6 can be a bolt, the first limiting part 61 can be the head of a bolt, and the limiting nut 62 can be threadedly connected to the first rotating shaft 6.

[0036] For example, refer to Figure 3 As shown, the first bracket 32 ​​and the second bracket 42 are arranged in pairs along the second direction. The two first brackets 32 are located on opposite sides of the first end plate 31 in the second direction, and the two second brackets 42 are located on opposite sides of the second end plate 41. The second bracket 42 can be located outside the first bracket 32. The first rotating shaft 6 passes through the second bracket 42 and the first bracket 32 ​​sequentially from the outside to the inside. The limiting nut 62 is screwed inside the first bracket 32.

[0037] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the first bracket 32 ​​has a first limiting block 33. When the rotating plate 4 rotates relative to the first fixed plate 3 until the second end plate 41 is perpendicular to the first end plate 31, the second bracket 42 abuts against the first limiting block 33. The end of the second bracket 42 near the first end plate 31 may have a semi-circular ear. When the second bracket 42 rotates to the vertical position of the mounting platform 51, the side of the semi-circular ear of the second bracket 42 abuts against the first limiting block 33, thereby limiting the second end plate 41 to a vertical position.

[0038] In one exemplary embodiment of this disclosure, reference is made to Figure 3 As shown, the first bracket 32 ​​has a second limiting block 34. When the rotating plate 4 rotates relative to the first fixed plate 3 until the second end plate 41 is parallel to the first end plate 31, the second bracket 42 abuts against the second limiting block 34. One end of the second bracket 42 near the first end plate 31 may have a semi-circular lug. During the rotation of the second bracket 42 around the first rotating axis 6, the semi-circular lug of the second bracket 42 can slide on the second limiting block 34. When the second bracket 42 rotates to the point where the mounting platform 51 is horizontal, the other side of the semi-circular lug of the second bracket 42 abuts against the second limiting block 34, thereby limiting the second end plate 41 to a horizontal position. The first limiting block 33 and the second limiting block 34 can be disposed on one side of the first bracket 32, for example, refer to... Figure 3 As shown, the first brackets 32 can also be set in pairs on both sides.

[0039] In one exemplary embodiment of this disclosure, the turntable 5 and the rotating plate 4 are rotatably connected via a second rotating shaft 7. For example, refer to... Figure 1 , Figure 3 As shown, the turntable 5 includes a turntable base plate 52 rotatably disposed on the surface of the rotating plate 4, and the turntable base plate 52 and the rotating plate 4 are rotatably connected by a second rotating shaft 7.

[0040] For example, multiple parallel second columns are provided between the rotating plate 4 and the mounting platform 51. For instance, refer to... Figure 1 , Figure 3 As shown, four parallel second columns can be provided between the rotating plate 4 and the mounting platform 51. The second columns can be evenly distributed on the top surface of the turntable base plate 52 and the bottom surface of the mounting platform 51. In an exemplary embodiment of this disclosure, the mounting platform 51 has a through mounting hole 53 at its center, which allows for the bottom wiring of the cylindrical antenna. The second columns can surround the bottom wiring of the cylindrical antenna, protecting the wiring and preventing interference between the wiring and the testing fixture.

[0041] In one exemplary embodiment of this disclosure, the surface of the rotating plate 4 near the turntable 5 is provided with scale lines surrounding the outer periphery of the turntable 5. Specifically, the surface of the second end plate 41 near the turntable base plate 52 is provided with scale lines surrounding the outer periphery of the turntable base plate 52. The tester can read the angle of rotation of the turntable 5 relative to the second end plate 41 from the scale lines, that is, the angle of rotation of the cylindrical antenna on the mounting platform 51 about its axis can be obtained.

[0042] In one exemplary embodiment of this disclosure, the mounting platform 51 is detachably connected to the second column. For example, the mounting platform 51 and the second column are detachably connected via a threaded connector. (See reference...) Figure 4 As shown, the top surface of the mounting platform 51 may have a countersunk hole, and the top of the second column may have a blind hole. The mounting platform 51 and the second column can be fastened together with bolts. In an exemplary embodiment of this disclosure, the second column is detachably connected to the rotating plate 4. For example, the second column is detachably connected to the turntable base plate 52 via a threaded connector.

[0043] In one exemplary embodiment of this disclosure, the antenna testing fixture provided is made of non-metallic materials. Specifically, the base plate 1, the raised portion 2, the first fixing plate 3, the rotating plate 4, and the turntable 5 are all made of non-metallic materials. Testing fixtures made of non-metallic materials are lighter and easier to operate, thus increasing testing efficiency and saving equipment and labor costs. Exemplarily, the antenna testing fixture does not contain any metallic materials; that is, all components of the testing fixture, including threaded connectors, are made of non-metallic materials, which avoids the influence of metal on the antenna testing results.

[0044] For example, the first end plate 31 is provided with a hollowed-out portion that passes through the first end plate 31, and the hollowed-out portion can reduce the weight of the first end plate 31.

[0045] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
