[0007] In one specific embodiment, the support component includes a fixing ring sleeved on the bottom of the base rod, and the surface of the fixing ring is fixedly connected with a plurality of connecting blocks in a ring array. The surface of the connecting blocks is movably connected with a square rod, one end of the square rod is sleeved with a sleeve rod, and one end of the sleeve rod is movably connected with an irregularly shaped plate.

[0008] In a specific embodiment, a threaded hole is provided on the side of the other end of the sleeve rod, and a threaded cap for adjusting the sliding tightness of the square rod is provided inside the threaded hole. Threaded holes are provided at both ends of the irregular plate surface, and threaded nails for fixing are provided inside the threaded holes.

[0009] In one specific embodiment, a support plate is fixedly connected to the side of the base plate, and an electric push rod is fixedly connected to the top of the support plate, while a toothed plate is fixedly connected to one end of the electric push rod.

[0010] In one specific embodiment, a T-shaped plate is fixedly connected to one side of the top of the base plate, and is slidably connected to the back of the toothed plate inside the T-shaped plate.

[0011] In a specific embodiment, a gear is rotatably connected to the center of the top of the base plate, and the surface of the gear meshes with the surface of the gear plate. A connecting seat is fixedly connected to the top of the gear, and a turntable (11) for antenna test scanning is provided on the top of the connecting seat (10).

[0012] Compared with the prior art, the present invention provides a scanning gantry turntable for antenna testing, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, by utilizing the setting of the support component, during antenna testing, the sleeve rod on the side of the bottom fixing ring can be pulled out from the surface of the square rod until the bottom surface of the irregular plate at one end is in contact with the ground, and the threaded nails on both sides are driven into the ground, thereby tightening the threaded caps, so that the length of the sleeve rod pulled out is fixed, thereby ensuring the stability of the bottom of the rod, avoiding shaking during antenna testing and scanning, and thus ensuring the accuracy of the test scanning data.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 In one embodiment of this utility model, a scanning rack turntable for antenna testing includes a base rod 1, an inner rod 2 sleeved on the top of the base rod 1, a support frame 3 sleeved on the top of the inner rod 2, a base plate 4 fixedly connected to the top of the support frame 3, and a support component 5 for adjusting support performance and improving the scanning stability of antenna testing sleeved on the bottom of the base rod 1.

[0022] The specific problem addressed in this embodiment is the lack of a supporting structure at the bottom, which causes swaying during antenna testing due to the need to adjust the orientation according to test requirements. This invention utilizes the support component 5 to allow the sleeve 54 on the side of the bottom fixing ring 51 to be pulled out from the surface of the square rod 53 during antenna testing, until the bottom surface of the irregular plate 55 at one end is in contact with the ground. The threaded nails 551 on both sides are then driven into the ground, tightening the threaded caps 541. This fixes the length of the sleeve 54 pulled out, ensuring the stability of the bottom of the base rod 1 and preventing swaying during antenna testing and scanning, thus ensuring the accuracy of the test scan data.

[0023] The support component 5 includes a fixing ring 51 sleeved on the bottom of the base rod 1. The surface of the fixing ring 51 is fixedly connected with a plurality of connecting blocks 52 in a ring array. The surface of the connecting blocks 52 is movably connected with a square rod 53. One end of the square rod 53 is sleeved with a sleeve rod 54, and one end of the sleeve rod 54 is movably connected with a shaped plate 55. In this specific embodiment, a threaded hole is opened on the side of the other end of the sleeve rod 54, and a threaded cap 541 for adjusting the sliding tightness of the square rod 53 is provided inside the threaded hole. Both ends of the surface of the shaped plate 55 are provided with threaded holes, and threaded nails 551 for fixing are provided inside the threaded holes. During antenna testing, the sleeve 54 on the side of the bottom fixing ring 51 can be pulled out from the surface of the square rod 53 until the bottom surface of the irregular plate 55 at one end is in contact with the ground. The threaded nails 551 on both sides are then driven into the ground, thereby tightening the threaded caps 541. This fixes the length of the sleeve 54 pulled out, thus ensuring the stability of the bottom of the base rod 1 and preventing shaking during antenna testing and scanning, thereby ensuring the accuracy of the test scanning data.

[0024] In this specific embodiment, a support plate is fixedly connected to the side of the base plate 4, and an electric push rod 6 is fixedly connected to the top of the support plate. One end of the electric push rod 6 is fixedly connected to a toothed plate 7. A T-shaped plate 8 is fixedly connected to one side of the top of the base plate 4, and is slidably connected to the back of the toothed plate 7 inside the T-shaped plate 8. A gear 9 is rotatably connected to the middle of the top of the base plate 4, and the surface of the gear 9 meshes with the surface of the toothed plate 7. A connecting seat 10 is fixedly connected to the top of the gear 9, and a turntable 11 for antenna testing is provided on the top of the connecting seat 10.
