[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] This embodiment provides a digital X-ray support mechanism, including an adjustment housing 1, an adjustment groove 11 inside the adjustment housing 1, and an adjustment part 2, which is slidably installed in the adjustment groove 11. The lower end of the adjustment part 2 is slidably engaged with a mounting part 3. The sliding adjustment part 2 changes the position of the mounting part 3, and the mounting part 3 can be used to clamp tubes with different curvatures.

[0032] like Figure 1 , Figure 2As shown, a cover plate 12 is fixedly installed on the upper end of the adjusting housing 1. An adjusting screw hole is opened on the upper surface of the cover plate 12. An adjusting bolt 121 is installed in the adjusting screw hole. One end of the adjusting bolt 121 is bolted into the adjusting block 21. The position of the adjusting block 21 is adjusted by rotating the adjusting bolt 121.

[0033] like Figure 2 , Figure 4 As shown, a positioning screw hole 112 is provided through the side wall of the adjusting housing 1, and a positioning bolt 111 is installed in the internal thread of the positioning screw hole 112;

[0034] like Figure 3 As shown, the adjustment part 2 includes an adjustment block 21, which is slidably installed in the adjustment groove 11. A fixing groove 22 is provided through the side wall of the adjustment block 21. The side wall of the fixing groove 22 has a wave-shaped structure. The adjustment bolt 121 is rotated to adjust the position of the adjustment block 21, so that the adjustment block 21 slides along the adjustment groove 11 to adjust the position of the installation part 3 to suit pipes of different radii. The positioning bolt 111 in the positioning screw hole 112 is tightened. The positioning bolt 111 passes through the fixing groove 22 to fix the adjustment block 21.

[0035] like Figure 5 , Figure 9 As shown, a limiting groove 23 is provided on the lower surface of the adjusting block 21, and a slot 231 is provided on the upper surface of the limiting groove 23. The slot 231 slopes downward from the opening of the limiting groove 23 into the interior of the limiting groove 23.

[0036] like Figure 7 As shown, the mounting part 3 includes a clamping block 31, and a limiting block 311 is fixedly installed on the upper surface of the clamping block 31. The limiting block 311 is slidably installed in the limiting groove 23. The limiting block 311 is a trapezoidal structure that is adapted to the limiting groove 23.

[0037] like Figure 7 , Figure 8 As shown, the upper surface of the limiting block 311 is provided with a telescopic groove 312, and the limiting part 33 is slidably installed in the telescopic groove 312;

[0038] like Figure 8 As shown, the limiting part 33 includes a positioning block 331, which is slidably installed in the telescopic groove 312. The upper end of the positioning block 331 is provided with an oblique angle that slopes downward from the opening of the limiting groove 23 into the limiting groove 23.

[0039] like Figure 6As shown, two mounting slots 32 are symmetrically formed on the side wall of the clamping block 31. A pull shaft 333 is fixedly installed on the lower surface of the positioning block 331. One end of the pull shaft 333 passes through the telescopic groove 312 and is located in the mounting slot 32. A spring 332 is fixedly installed at the bottom of the telescopic groove 312. The other end of the spring 332 is fixedly installed on the lower surface of the positioning block 331. Pulling the pull shaft 333 downwards causes the positioning block 331 to retract into the telescopic groove 312, releasing the locking between the positioning block 331 and the groove 231. The limiting block 311 can be slid out from the limiting groove 23. Depending on the curvature of the pipe to be clamped and fixed, different mounting parts 3 can be replaced. The limiting block 311 of the new clamping block 31 is pushed into the limiting groove 23. When the positioning block 331 is aligned with the groove 231, the spring 332 pushes the positioning block 331 into the groove 231, which automatically locks the mounting part 3 to prevent it from falling off. This allows for quick replacement of the clamping block 31 to match pipes with different curvatures without replacing the entire mechanism.

[0040] like Figure 6 As shown, the lower surface of the clamping block 31 has several mounting screw holes, and several mounting bolts 321 are installed in the internal threads of the mounting screw holes. A washer 322 is fixedly installed at one end of the mounting bolt 321. The washer 322 is made of flexible material, preferably flexible rubber material, to prevent scratching the surface of the tube body during clamping.

[0041] In practical use, the adjusting block 21 is installed into the adjusting groove 11 of the adjusting housing 1, and the adjusting bolt 121 is rotated to adjust the position of the adjusting block 21 so that the adjusting block 21 slides along the adjusting groove 11 to adjust the position of the mounting part 3 to suit pipes of different radii. The positioning bolt 111 in the positioning screw hole 112 is tightened and passes through the fixing groove 22 to fix the adjusting block 21. Pulling down the shaft 333 retracts the positioning block 331 into the telescopic groove 312, releasing the lock between the positioning block 331 and the groove 231. This allows the limiting block 311 to slide out of the limiting groove 23. Depending on the required pipe curvature, different mounting parts 3 can be used. The new clamping block 31's limiting block 311 is pushed into the limiting groove 23. When the positioning block 331 aligns with the groove 231, the spring 332 pushes the positioning block 331 into the groove 231, automatically locking the mounting part 3 to prevent it from falling off. This allows for quick replacement of the clamping block 31. By replacing clamping blocks 31 with different curvatures, various pipe types can be adapted without replacing the entire support mechanism, significantly improving testing efficiency. The pipe to be tested is placed under the clamping block 31, with the gasket 322 pressed against the pipe surface. The flexible design of the gasket 322 prevents scratching the pipe.
