The upper sliding block 15 is slidably connected to the arc slot 143 and the straight slot 133, so that the index plate 142 and the vertical plate 132 can be fixed at a relative rotation angle and position. In other words, the lower sliding block 16 rotatably and slidably connects the overturning tray 14 and the connecting plate 13, and the upper sliding block 15 fixes the relative rotation angle and position of the overturning tray 14 and the connecting plate 13.

[0045] The non-metal binding belt passes through different through holes on the bearing plate 141 to bind and fix different sizes of standard test bodies on the overturning tray 14. Preferably, the bearing plate 141 can be horizontally arranged, can be overturned with the index plate 142 around the overturning hole 144, and can move along the straight slot 133. In other words, the standard test body can be horizontally arranged on the bearing plate 141 and can rotate with the overturning tray 14 around the overturning hole 144 and move along the straight slot 133.

[0046] The universal test support provided in this embodiment of the utility model has multiple adjustment structures: ① Adjusting the height of the lifting support 12: Loosening the quick-press clamp 123 can adjust the relative position of multiple sleeves 122, that is, adjust the height of the lifting support 12; tightening the quick-press clamp 123 can increase the support strength of the lifting support 12; ② Adjusting the angle of the flip tray 14: Loosen the upper slider 15 and the lower slider 16 at the same time, slide the flip tray 14 along the straight groove 133 to adjust to the required height, tighten the lower slider 16, rotate it along the arc groove 143 to the required angle, and tighten the upper slider 15; ③ Adjusting the position of the lifting support 12: When the standard test body needs to be placed close to the side wall, it is necessary to adjust the position of the lifting support 12 on the base 3. Loosen the flange 121 used to connect the base 3 and the lifting support 12, install the lifting support 12 in the fixing hole 31 on the side of the base 3 near the side wall, and tighten the connecting flange 121.

[0047] like Figure 4 As shown, taking a transmission-type cargo security inspection device as an example, its X-ray incident direction is vertically downward, and the point to be inspected is the center point of the channel. The adjustment steps are as follows: ① Place the base 3 in the center of the transmission mechanism; ② Install the lifting bracket 12 in the middle of the base 3; ③ Adjust the height of the lifting bracket 12 so that the standard test body is placed at half the height of the security inspection machine channel; ④ Set the angle of the flip tray 14 to 0° so that the standard test body is placed horizontally.

[0048] like Figure 5 As shown, taking a transmission-type cargo security inspection device as an example, its X-ray incident direction is emitting at a 45° angle downwards from the upper left, and the point to be inspected is located close to the right side wall of the security inspection machine. The adjustment steps are as follows: ① Place the base 3 on the left side of the transmission mechanism, close to the left side wall of the security inspection machine; ② Install the lifting bracket 12 on the left side of the base 3; ③ Adjust the height of the lifting bracket 12 to the highest position; ④ Set the angle of the flipping tray 14 to 45° so that the X-rays irradiate the standard test object perpendicularly.

[0049] In summary, the universal support for test subjects in a transmissive cargo security inspection device provided by this utility model allows for height adjustment via a telescopic sleeve structure and straight groove, angle adjustment via an arc groove and flip hole, and spacing adjustment via fixed holes. It is suitable for the testing requirements regarding the "placement position and orientation" of test subjects in GB15208.3—2018 "Micro-dose X-ray Security Inspection Equipment Part 3: Transmissive Cargo Security Inspection Equipment". The operation time for a single height and angle adjustment does not exceed 5 minutes, and the time for installing and removing a standard test subject does not exceed 10 minutes, making it far more convenient to operate than existing testing devices.
