[0002] Industrial CT refers to the nuclear imaging technology applied in industry. Its basic principle is based on the weakening and absorption characteristics of radiation in the detected object. The absorption ability of matter to radiation is related to the properties of matter. Therefore, the attenuation law and distribution of X-rays or gamma rays emitted by radioactive nuclides or other radiation sources with certain energy and intensity in the detected object can obtain detailed information of the object inside by the detector array, and finally the information is processed and image reconstruction technology is used to display in the form of image.

[0003] The traditional sample fixed subassembly has many drawbacks. Some fixed subassembly structures are complex, and the disassembly and installation process is time-consuming and laborious, which greatly reduces the efficiency of detection work. For example, some fixed devices use multiple screws, and each time the sample is replaced, the screws need to be loosened and tightened one by one, which is complicated to operate. Some fixed subassembly lacks flexibility and cannot adapt to samples of different shapes and sizes, which leads to frequent replacement of fixed subassembly when detecting diversified products, increasing detection cost and time cost.

[0030] Please refer to Figures 1-5 , the sample fixing assembly convenient to detach for industrial CT scanning, including base 1, the top surface of base 1 is provided with opposite first support column 2 and second support column 3, the outer surface of first support column 2 and second support column 3 is fixedly connected with bearing 4, the outer surface of bearing 4 is fixedly connected with symmetrical support rod 5, the outer surface of first support column 2 is fixedly connected with supporting plate 6 through support rod 5, the top surface of the end of supporting plate 6 close to support rod 5 is fixedly connected with first antiskid baffle 7, the outer surface of second support column 3 is fixedly connected with pressing plate 8 through support rod 5, the bottom surface of the end of pressing plate 8 close to bearing 4 is fixedly connected with second antiskid baffle 9, the position of supporting plate 6 below pressing plate 8.

[0031] Please refer to Figure 3 And Figure 4 , the surface of supporting plate 6 and pressing plate 8 is provided with threaded hole 16, the inner wall of threaded hole 16 is threadedly connected with bolt 17, one end of bolt 17 is fixedly connected with antiskid block 19, and antiskid block 19 contacts with the sample.

[0032] After limiting the sample, the sample can be located on the surface of antiskid block 19 by rotating bolt 17, so that the two ends of the sample at supporting plate 6 and pressing plate 8 are further limited, and the small sample is directly limited by bolt 17 and antiskid block 19, and the bolt 17 is directly rotated and removed when removed.

[0033] Please refer to Figure 1 And Figure 3 , the top surface of base 1 is provided with a plurality of equidistantly distributed sliding grooves 11, the bottom end of first support column 2 and second support column 3 is provided with sliding block 10, and sliding block 10 and sliding groove 11 are both T-shaped.

[0034] The relative distance of first support column 2 and second support column 3 can be conveniently adjusted, and the stability of sliding block 10 is maintained.

[0035] Please refer to Figure 3 And Figure 5 , the top end of sliding block 10 is fixedly connected with screw rod 12, the bottom end of first support column 2 and second support column 3 is provided with threaded groove 14, and screw rod 12 is normally located in the inner wall of threaded groove 14.

[0036] The first support column 2 and the second support column 3 can be rotated directly to adjust the working height of the pallet 6 and the pressure plate 8.

[0037] Please see Figure 1 and Figure 3 The bottom outer surface of the screw 12 is threaded with a fastening nut 13, and the bottom surface of the fastening nut 13 is in contact with the top surface of the base 1.

[0038] This facilitates the positioning and fastening of the first support column 2 and the second support column 3 at their determined locations.

[0039] Please see Figure 1 and Figure 4 The top surfaces of the first support column 2 and the second support column 3 are both fixedly connected to the torsion block 15, and the end of the bolt 17 away from the anti-slip block 19 is fixedly connected to the rotating block 18.

[0040] The rotating block 18 facilitates the rotation of the entire assembly from the top of the first support column 2 and the second support column 3, and also facilitates the torsion of the bolt 17.

[0041] During operation, the relative distance between the first support column 2 and the second support column 3 is adjusted according to the sample's specifications and dimensions by moving the sliding slider 10 within the groove 11 of the base 1. This adjusts the distance to accommodate the sample's length and width. Then, the fastening nut 13 is loosened, and the first and second support columns 2 and 3 are rotated. Through the engagement of the screw 12 and the threaded groove 14, the height of the support plate 6 and the pressure plate 8 is adjusted to accommodate the sample's thickness. The sample is then placed on the support plate 6, with one end of the sample abutting against the first anti-slip baffle 7. The first and second support columns 2 and 3 are rotated, causing the pressure plate 8 to press against the sample, while simultaneously causing the other end of the sample abutting against the second anti-slip baffle. 9. This initially fixes the sample. For larger samples, the bolt 17 can be rotated further to make the anti-slip block 19 contact the sample, further limiting and fixing the sample. For smaller samples, the bolt 17 and anti-slip block 19 can be used directly for fixing. This device can adapt to samples of various specifications, shapes and sizes by adjusting the position and height of the first support column 2 and the second support column 3 as well as the bolt 17, improving the versatility of the fixing components. The cooperation of the support plate 6, the pressure plate 8 and the first anti-slip baffle 7 and the second anti-slip baffle 9 can provide a stable clamping force for the sample, ensuring that the sample does not shift during the scanning process.

[0042] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
