[0024] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the anti-interference satellite navigation antenna testing device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0025] Please refer to Figure 2 and Figure 3 This embodiment provides an anti-interference satellite navigation antenna test device, including: a base 1, a first side plate 2, a second side plate 3, a third side plate 4, a fourth side plate 5, a fifth side plate 6, and a sixth side plate 7; wherein, the base 1 is square, and the edge of the base 1 is provided with multiple clamping holes 10 for easy installation onto a test platform. Hexagonal holes 11 are provided on the base 1, and the edges of the hexagonal holes are provided with multiple screw holes 12 for installing the first side plate 2, the second side plate 3, the third side plate 4, the fourth side plate 5, the fifth side plate 6, and the sixth side plate 7. The first side plate 2, the second side plate 3, the third side plate 4, the fourth side plate 5, the fifth side plate 6, and the sixth side plate 7 are fixed on the base 1 at preset positions, with the inner bottom edge of each side plate coinciding with the edge of the hexagonal hole. Multiple fasteners 8 are provided on the top surface of the first side plate, the second side plate, the third side plate, the fourth side plate, the fifth side plate, and the sixth side plate to secure the product under test.

[0026] For details, please refer to Figure 3The base 1 is 730mm long and 440mm wide. The four corners of the base 1 are beveled to remove burrs and flash, resulting in a smooth and aesthetically pleasing surface. The product heading, tooling number, and name can be marked on the upper surface of the base 1. The specific marking locations can be determined according to requirements; for example, the product heading can be marked on the upper right of the base surface, and the tooling number and name can be engraved on the lower right. The font can be SimSun, with a character height of 8mm. The aspect ratio of the tooling name can be 75%, and the engraving depth is 0.3mm, with the characters engraved in black paint. Laser engraving provides longer-lasting markings compared to labeling, improving device identification.

[0027] In this embodiment, the included angle between the first side plate 2 and the second side plate 3 on the base 1 is 80°, the included angle between the second side plate 3 and the third side plate 4 is 140°, the included angle between the third side plate 4 and the fourth side plate 5 is 140°, the included angle between the fourth side plate 5 and the fifth side plate 6 is 80°, the included angle between the fifth side plate 6 and the sixth side plate 7 is 140°, and the included angle between the sixth side plate 7 and the first side plate 2 is 140°. Each side plate is fixed to the base 1 using hex socket head cap screws, and the entire hex socket head cap screw is recessed into the screw hole, ensuring that the cylindrical head does not protrude from the base and cause instability at the bottom of the base.

[0028] Please refer to Figure 4 The first side plate 2, the second side plate 3, the third side plate 4, the fourth side plate 5, the fifth side plate 6, and the sixth side plate 7 have at least three different heights, so that the surface formed after they are installed on the base is inclined.

[0029] A window 9 is opened on each of the following side panels: the first side panel 2, the second side panel 3, the third side panel 4, the fourth side panel 5, the fifth side panel 6, and the sixth side panel 7. Please refer to [the document / reference]. Figure 5 Window 9 is a rounded trapezoid with one side perpendicular to the two base sides, and the gradient of the windows on different side panels is different. In this embodiment, each side panel can be regarded as a right trapezoid shape, and the height and gradient of each side panel are different, and the windows of each side panel are also somewhat different.

[0030] The aforementioned anti-jamming satellite navigation antenna test device can be fixed as a whole on a vibration testing device. When an anti-jamming satellite navigation antenna, such as the D-TTX-609, is installed on this device, the test status and data from this device better reflect the D-TTX-609 anti-jamming satellite navigation antenna under real-world operating conditions during triaxial vibration testing. It can demonstrate the vibration data of the D-TTX-609 anti-jamming satellite navigation antenna under various conditions; the vibration magnitude is significantly improved; and the testing process is more convenient, safer, and more realistic and reliable.
