Description

Technical Field

[0001] This utility model relates to a universal support for the test body of a transmissive baggage security inspection device, belonging to the technical field of security inspection equipment. Background Technology

[0002] Transmissive baggage security inspection equipment is a type of low-dose X-ray security inspection equipment used to inspect luggage and parcels. The height and width of any inspection channel entrance are less than 1.1m. The national standard GB15208.2—2018, "Low-dose X-ray Security Inspection Equipment Part 2: Transmissive Baggage Security Inspection Equipment," specifies the specifications of the test subjects used for inspecting transmissive baggage security inspection equipment, as well as the placement and orientation of the test subjects. This "placement and orientation" depends on the relative position of the X-ray generating device and the detector of the equipment. The plane of the test subject should be perpendicular to the direction of radiation emission and placed as close as possible to the X-ray generating device to obtain the best test subject image.

[0003] Chinese invention patent ZL 201310018775.7 discloses a testing device for inspecting cargo X-ray security inspection equipment. The technical solution includes a base, a lift, a first test body mounting base, a second test body mounting base, and a control unit. The lift includes a folding arm, a hydraulic rod, a pan-tilt unit, four pulleys, a pressure-reducing handle, and a pressure-increasing handle. A pair of slide rails are provided on both sides of the pan-tilt unit, and limiting blocks at the ends of the slide rails prevent the first test body mounting base from sliding off the slide rails. The first test body mounting base has an active turntable and a driven turntable. The active turntable has an active mounting block, and the driven turntable has a driven mounting block for mounting the first test body. A turntable motor is mounted on the active turntable, driving the active mounting block to rotate. An angle scale is marked on the active mounting block, which, in conjunction with the scale pointer on the active turntable, allows the current rotation angle to be read. The second test body mounting rod is located on one side of the gimbal. When in use, the two second test body mounting rods are folded out to be perpendicular to the side of the gimbal. Then, the two second test body support frames are respectively installed on the two opposite second test body mounting rods with screws to achieve the positioning of the test angle of the second test body.

[0004] Similarly, existing testing devices are too large to be used with transmissive baggage security inspection equipment. Furthermore, their structural design limits the placement of standard test subjects close to the side wall of the security checkpoint, failing to meet national standards regarding the "placement position and orientation" of test subjects. Alternatively, the metal supports and lifting components used may interfere with the imaging image. Summary of the Invention

In this embodiment of the invention, the test body described in the national standard is referred to as the standard test body.

[0036] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides a universal support for the test body of a transmissive baggage security inspection device, including a first lifting and tilting assembly 1, a second lifting and tilting assembly 2, and a guide rail 3. The first lifting and tilting assembly 1 includes a base 11, a lifting bracket 12, a connecting plate 13, a tilting tray 14, an upper slider 15, and a lower slider 16. The structure of the second lifting and tilting assembly 2 is the same as that of the first lifting and tilting assembly 1, and will not be described again.

[0037] The base 11 is made of a non-metallic high-density composite material plate, which does not affect the X-ray transmission imaging of the standard test object. The base 11 has multiple fixing holes 111, corresponding to the bottom holes of the lifting bracket 12, for connecting the lifting bracket 12 and the base 11. Preferably, the base 11 includes multiple fixing holes 111 in different positions, for connecting the lifting bracket 12 at different locations on the base 11. Optionally, the base 11 includes multiple fixing holes 111, corresponding to the conveying device of the transmission-type baggage security inspection equipment, for connecting the base 11 and the conveying device. The upper surface of the base 11 is provided with a sliding shoe 112, which is slidably connected to the guide rail 3.

[0038] The lifting support 12 includes a flange 121, multiple sleeves 122, and a quick-release clamp 123. The multiple sleeves 122 are coaxially arranged and interlocked to form a telescopic structure. Optionally, the sleeves 122 are hollow tubes made of non-metallic material, which does not affect the X-ray transmission imaging of the standard test object. The quick-release clamp 123 is located at the connection between the sleeves 122 and is designed for quick fixing and releasing of the sleeves 122. The upper end of the flange 121 contacts and connects to the lower end of the lowest sleeve 122, and is coaxially arranged with the sleeve 122. The lower end of the flange 121 is designed with a flange hole structure for connecting and fixing the lifting support 12 to the base 11. In other words, the flange hole at the lower end of the lifting support 12 corresponds to the fixing hole 111 of the base 11 for connecting the lifting support 12 and the base 11.

[0039] The connecting plate 13 includes a horizontal plate 131, a vertical plate 132, and a straight groove 133. One end of the horizontal plate 131 contacts and connects to the upper end of the vertical plate 132, forming a predetermined angle, for example, perpendicular to each other. The vertical plate 132 has a straight groove 133, which is a hollow groove structure extending along the length of the vertical plate 132. The depth direction of the straight groove 133 is perpendicular to the surface of the vertical plate 132.

[0040] The flip-over tray 14 includes a support plate 141, an indexing plate 142, an arc groove 143, and a flip-over hole 144. One end of the support plate 141 contacts and connects to the lower end of the indexing plate 142, forming a predetermined angle, for example, perpendicular to each other. The lower end of the indexing plate 142 is provided with the flip-over hole 144, which is a through-hole structure with its depth direction perpendicular to the surface of the indexing plate 142. The indexing plate 142 is provided with the arc groove 143, which is a hollow groove structure extending along an arc direction centered on the flip-over hole 144. The depth direction of the arc groove 143 is perpendicular to the surface of the indexing plate 142.

[0041] like Figure 3As shown, the included angle between the virtual leads at both ends of the flip hole 144 and the arc groove 143 is the design angle α, for example, α is 45° to 180°. In other words, the flip angle range of the flip tray 14 around the flip hole 144 is 0° to 45° to 0° to 180°. Preferably, the support plate 141 is provided with multiple through holes for passing through the binding straps.

[0042] Guide rail 3 is a sliding guide rail, and its structure corresponds to that of slide shoe 112. Slide shoe 112 can be slidably connected to guide rail 3.

[0043] The sliding shoe 112 of the first lifting and tilting assembly 1 is fixed to the base 11 and connected to one end of the guide rail 3. The sliding shoe 112 and the base 11 can slide along the guide rail 3. The sliding shoe of the second lifting and tilting assembly 2 is slidably connected to the other end of the guide rail 3. The first lifting and tilting assembly 1 and the second lifting and tilting assembly 2 form a connection structure through the guide rail 3, and their relative positions can be adjusted and fixed by the sliding shoe 112, that is, the distance between them can be adjusted. The tilting trays of the first lifting and tilting assembly 1 and the second lifting and tilting assembly 2 are arranged opposite each other in the horizontal direction.

[0044] Multiple sleeves 122 are coaxially arranged and interlocked to form a telescopic structure. A quick-press clamp 123 is located at the connection point between sleeves 122 for fixing and releasing them. The upper end of a flange 121 contacts and connects to the lower end of the lowest sleeve 122, and is coaxially arranged with it. The bottom surface of the flange 121 contacts and connects to the base 11. In other words, the lifting bracket 12 is perpendicular to the base 11, and its lower end contacts and connects to the base 11. The height of the lifting bracket 12 can be changed by adjusting the quick-press clamp 123 and the relative positions of the multiple sleeves 122.

[0045] The horizontal plate 131 contacts and connects to the upper end of the lifting bracket 12. The vertical plate 132 and the straight groove 133 extend downward parallel to the lifting bracket 12 and perpendicular to the base 11. The lower slider 16 is rotatably connected to the flip hole 144 and slidably connected to the straight groove 133, allowing the indexing plate 142 and the vertical plate 132 to be rotatably and slidably connected. The upper slider 15 is slidably connected to the arc groove 143 and the straight groove 133, allowing the indexing plate 142 and the vertical plate 132 to be fixed at their relative rotation angles and positions. In other words, the lower slider 16 allows the flip tray 14 and the connecting plate 13 to be rotatably and slidably connected, and the upper slider 15 allows the flip tray 14 and the connecting plate 13 to be fixed at their relative rotation angles and positions.

[0046] Non-metallic binding straps pass through different through holes in the support plate 141 to secure standard test pieces of different sizes to the flip tray 14. Preferably, the support plate 141 can be horizontally positioned, can rotate around the flip hole 144 with the indexing plate 142, and can move along the straight groove 133. In other words, the standard test piece can be horizontally positioned on the support plate 141 and rotate around the flip hole 144 with the flip tray 14, and move along the straight groove 133. Optionally, the angular rotation range of the indexing plate 142 and the flip tray 14 relative to the connecting plate 13 is 0° to 180°. Preferably, the angular rotation range of the indexing plate 142 and the flip tray 14 relative to the connecting plate 13 is 0° to 90°.

[0047] 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 flipping tray 14: Simultaneously loosening the upper slider 15 and the lower slider 16, sliding the flipping tray 14 along the straight groove 133 to adjust to the required height, tightening the lower slider 16, rotating it along the arc groove 143 to the required angle, and tightening the upper slider 15; ③ Adjusting Position of lifting bracket 12: When the standard test body needs to be placed close to the side wall, the position of lifting bracket 12 on base 11 needs to be adjusted. Loosen the flange 121 used to connect base 11 and lifting bracket 12, install lifting bracket 12 in the fixing hole 111 on the side of base 11 near the side wall, and tighten the connecting flange 121; ④ Adjust the spacing of base 11: When the size of the standard test body changes or the placement direction changes, loosen the slipper 112 on guide rail 3, adjust the distance between bases 11 to adapt to the placement distance of the standard test body, and tighten the slipper 112 on guide rail 3.

[0048] like Figure 4 As shown, taking the X-ray transmission baggage security inspection equipment to be inspected 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 11 in the center of the transmission mechanism; ② Install the lifting bracket 12 in the middle of the base 11; 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.

[0049] like Figure 5As shown, taking a transmission-type baggage security inspection device as an example, its X-ray incident direction is emitted at a 45° angle upward from the lower right side, 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 11 on the right side of the transmission mechanism, close to the right side wall of the security inspection machine; ② Install the lifting bracket 12 on the right side of the base 11; ③ Adjust the height of the lifting bracket 12 to the lowest position; ④ Set the angle of the flip tray 14 to 45° so that the X-rays irradiate the standard test object perpendicularly.

[0050] In summary, the universal support for test subjects in a transmissive baggage 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 guide rails. It is suitable for the testing requirements regarding the "placement position and orientation" of test subjects in GB15208.2—2018 "Micro-dose X-ray Security Inspection Equipment Part 2: Transmissive Baggage 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.
