[0032] Embodiment:

[0033] As Figure 1 shown, the present utility model provides a reverse radar test stand, a base 101, and a fixing component for connecting with the ground is arranged on the base 101. The fixing component includes a plurality of support seats 102 arranged on the base 101. A fixing bolt 103 is inserted into the support seat 102, and the fixing bolt 103 is screwed with the test ground. During use, the position of the base 101 is fixed by screwing the fixing bolt 103 with the test ground to complete the installation of the device. In addition, in some embodiments, a counterweight can also be added to the base 101 so that the test stand is not easily displaced during the test and can be freely moved by the staff.

[0034] As Figure 3As shown, in this embodiment, a mounting seat 204 is provided on the base 101. The mounting seat 204 is connected to the base 101 through an adjustment component. The position of the mounting seat 204 in the two-dimensional plane is adjusted through the adjustment component. A test rod 301 is provided on the mounting seat 204. The bottom of the test rod 301 is movably connected to the mounting seat 204. The adjustment component includes a movable frame 201 slidably arranged on the base 101. The mounting seat 204 is slidably arranged on the movable frame 201, and the sliding direction of the movable frame 201 intersects with the sliding direction of the mounting seat 204. A rotatable first lead screw 104 is provided on the base 101. The movable frame 201 is screwed to the first lead screw 104. A first knob 105 is provided at the end of the first lead screw 104. A rotatable second lead screw 202 is provided on the movable frame 201. The mounting seat 204 is screwed to the second lead screw 202. A second knob 203 is provided at the end of the second lead screw 202.

[0035] During the testing process, the first knob 105 can also be rotated to drive the first lead screw 104 to rotate. During the rotation of the first lead screw 104, the movable frame 201 is driven to slide on the base 101. By rotating the second knob 203, the second lead screw 202 is driven to rotate. During the rotation of the second lead screw 202, the mounting seat 204 is driven to slide on the movable frame 201, so as to freely adjust the position of the test rod 301 in the two-dimensional plane, thereby adjusting the test position and test distance, and improving the practicability and functionality of the test stand.

[0036] As Figure 2 shown, in this embodiment, a flexible block 206 is fixedly provided on the mounting seat 204. The bottom of the test rod 301 is fixedly connected to the flexible block 206. The test stand further includes a plurality of sets of tension springs 304. The plurality of sets of tension springs 304 are circumferentially arranged on the mounting seat 204. A plurality of sets of first pull rings 205 are provided on the mounting seat 204. A plurality of sets of second pull rings 303 are circumferentially arranged on the circumferential side of the test rod 301. The two ends of the tension spring 304 are respectively connected to the first pull ring 205 and the second pull ring 303.

[0037] The setting of the flexible block 206 enables the test rod 301 to move freely on the mounting seat 204. When the plurality of sets of tension springs 304 are circumferentially arranged, due to their equal pulling forces, the test rod 301 is always perpendicular to the mounting seat 204 when not subject to external forces. When the test rod 301 is impacted and displaced, several of the tension springs 304 are stretched and the flexible block 206 is squeezed, so that the test rod 301 can automatically return under the reset ability of the tension springs 304, without the need for the staff to repeatedly adjust the position of the test rod 301, reducing the positioning process. And a protective layer 302 is wrapped around the circumferential side of the test rod 301. The protective layer 302 is made of a flexible material, and the vehicle impact is protected by the flexible protective layer 302, reducing test losses.

[0038] Specific usage mode and beneficial effects of the present utility model:

[0039] When in use, the test stand is fixed to the ground through the fixing bolt 103. After adjusting the positions of the mounting seat 204 and the test rod 301 in the two-dimensional plane by rotating the first lead screw 104 and the second lead screw 202, the reverse radar test can be carried out. During the test, if the vehicle or the staff collides with the test rod 301, the test rod 301 will be driven to tilt, and the tension spring 304 will be stretched. After the test is completed, the test rod 301 can be automatically controlled to reset under the reset ability of the tension spring 304. Therefore, there is no need to repeatedly place and position the test rod 301 during multiple tests, effectively reducing the labor intensity of the staff during the test and improving the working efficiency of the test.
