[0002] X-ray fluorescence is mainly used to analyze and detect the elemental composition in samples. It identifies and quantitatively analyzes various elements in samples by emitting fluorescent X-rays of specific energy after the samples are excited. It is often used in geology, environmental monitoring, materials science, biomedicine and other fields. When using an X-ray fluorescence instrument, it is usually necessary to place the sample to be tested in a sample box or sample table for testing. The purpose of this is to ensure the stability and accuracy of the sample while avoiding potential radiation risks to the operator. By placing the sample in the sample box, it can be ensured that the X-rays can be accurately irradiated to the sample surface and the fluorescent signal emitted by the sample can be collected for analysis. Therefore, when using an X-ray fluorescence instrument, it is very important to place the sample correctly.

[0004] The prior art makes it very important to place the sample correctly when using an X-ray fluorescence spectrometer. However, the X-ray fluorescence spectrometer does not have a component to prevent the sample box from moving when in use. Therefore, after the sample box is placed on the top of the sample stage, the sample stage needs to be pushed to a suitable position. At this time, the moving force may cause the sample box to move. Therefore, an X-ray fluorescence spectrometer with a protective structure is proposed to solve the above problem. Utility Model Content

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0028] By adopting the above solution, by setting the travel groove 8 and the travel plate 9, when the movable plate 21 needs to be moved, the travel groove 8 and the travel plate 9 can control the moving position of the movable plate 21, so that the movable plate 21 will not move randomly when moving.

[0029] refer to Figure 3 The clamping assembly 6 includes a positioning block 61, the bottom of the positioning block 61 is rotatably connected to the top of the placement plate 23 through a rotating shaft, a rotating plate 62 is fixedly connected to the side of the positioning block 61 close to the matching hole 5, and a clamping block 63 is fixedly connected to the side of the rotating plate 62 away from the positioning block 61.

[0030] The above scheme is adopted: by setting the clamping assembly 6, when it is necessary to position the sample box on the top of the placement plate 23, the four rotating plates 62 move, and the rotating plates 62 rotate around the positioning block 61, and then the rotating plates 62 rotate to drive the clamping block 63 to clamp the sample box.

[0031] refer to Figure 3 An extrusion hole 10 is provided at the top of the rotating plate 62 , and an L-shaped extrusion rod 11 is movably connected to the inner cavity of the extrusion hole 10 . The L-shaped extrusion rod 11 is fixedly connected to the rotating block 3 at one side thereof close to the rotating block 3 .

[0032] The above scheme is adopted: by setting the extrusion hole 10 and the L-shaped extrusion rod 11, when it is necessary to control the rotation of the four rotating plates 62 at the same time, the rotation of the rotating block 3 will drive the four L-shaped extrusion rods 11 to move in the matching hole 5 and the extrusion hole 10, and the L-shaped extrusion rod 11 will squeeze the inner wall of the extrusion hole 10 to drive the four rotating plates 62 to move.

[0034] The above solution is adopted: by setting the limiting ring 12 and the limiting groove 13, when the rotating block 3 rotates, the limiting ring 12 and the limiting groove 13 can limit the rotation position of the rotating block 3, so that the rotating block 3 will not be separated from the placement plate 23.

[0035] refer to Figure 4 A polygonal groove 14 is provided at the bottom of the placement plate 23 , and the inner cavity of the polygonal groove 14 is plugged and connected to a polygonal block 15 .

[0036] By adopting the above scheme: by setting the polygonal groove 14 and the polygonal block 15, after the rotating block 3 is rotated to different positions, the polygonal block 15 is inserted into the polygonal groove 14, the rotating block 3 can be fixed at different positions, which is convenient for clamping sample boxes of different sizes.

[0037] refer to Figure 4 The positioning assembly 7 includes a pulling member 71, which is movably connected to the inner cavity of the mounting groove 4.

The top of the tension spring 72 is fixedly connected to the inner wall of the mounting groove 4. The left and right sides of the top of the pulling member 71 are fixedly connected with connecting blocks 73. The top of the connecting block 73 passes through the mounting groove 4 and is fixedly connected to the polygonal block 15.

[0038] The above scheme is adopted: by setting the positioning component 7, after the polygonal block 15 is inserted into the polygonal groove 14, the pulling force on the pulling member 71 is exerted by the tension spring 72, so that the pulling member 71 will not move, and the polygonal block 15 fixed on the top will not drive the polygonal block 15 to leave the polygonal groove 14.

[0039] The working principle of this utility model:

[0040] When in use, place the material to be tested in the box, then hold the pull rod 22 tightly to drive the moving plate 21 to move inside the fluorescent device 1, the movement of the moving plate 21 will drive the travel plate 9 to move in the travel groove 8, and then the moving plate 21 drives the placement plate 23 to move to a suitable position, and then place the sample box on the top of the placement plate 23, and then pull the pulling member 71 to pull the tension spring 72 in the installation groove 4, the connecting block 73 on the top of the pulling member 71 will drive the polygonal block 15 to descend, and after the polygonal block 15 descends and leaves the polygonal groove 14 and moves to a suitable position, the rotating pulling member 71 is rotated to drive the rotating block 3 to rotate, and the rotating block 3 rotates. The four L-shaped extrusion rods 11 are driven to move in the matching holes 5 and the extrusion holes 10. The L-shaped extrusion rods 11 squeeze the inner wall of the extrusion holes 10 to drive the four rotating plates 62 to move. The rotating plates 62 rotate around the positioning block 61. When the rotating plates 62 rotate to drive the clamping blocks 63 to clamp the sample box, the pulling piece 71 is released, and the tension spring 72 undergoes elastic deformation to drive the pulling piece 71 back to its original position. The movement of the pulling piece 71 will drive the polygonal block 15 on the top of the connecting block 73 to be inserted into the polygonal groove 14. At this time, the position of the rotating block 3 can be fixed, and then the rotating block 3 and the L-shaped extrusion rods 11 can position the position of the rotating plate 62.

[0041] In summary: the X-ray fluorescence instrument with a protective structure is used in conjunction with the placement component 2, the movable plate 21, the pull rod 22, the placement plate 23, the rotating block 3, the mounting groove 4, the matching hole 5 and the clamping component 6, and the positioning component 7. The rotation of the rotating block 3 will drive the four L-shaped extrusion rods 11 to move in the matching hole 5 and the extrusion hole 10. The L-shaped extrusion rods 11 squeeze the inner wall of the extrusion hole 10 to drive the four rotating plates 62 to move. The rotating plate 62 rotates around the positioning block 61. When the rotating plate 62 rotates, it drives the clamping block 63 to clamp the sample box, which solves the problem that the X-ray fluorescence instrument has no component to prevent the sample box from moving when in use. In this way, after the sample box is placed on the top of the sample stage, it is necessary to push the sample stage to a suitable position. At this time, the moving force may cause the sample box to move.
