Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1 to 2 As shown, a depth profile target box suitable for laser ablation technology includes a box body 1, multiple sample placement cavities 2 arranged regularly on the box body 1, a cover 3 that can be engaged and disengaged on the sample placement cavity 2 via a hinge assembly and opens and closes to the side of the box body 1, and a loading assembly 4 disposed in the sample placement cavity 2.

[0021] The box body 1 is the main structure of the entire target box, providing a mounting base for other components. Box body 1 can be divided into an inner box body 1 and an outer box body 1, forming a double-layer structure. Multiple regularly arranged sample placement cavities 2 can conveniently and orderly place multiple sample resin targets, providing space for accommodating and fixing the sample resin targets, facilitating sample placement and fixation, and simplifying subsequent laser ablation operations. The size and shape of each sample placement cavity 2 can be customized according to the type and size of the sample to ensure stable sample placement. The top of the sample placement cavity 2 has a circular opening, preferably designed as two rows and four columns. A rotating cover 3 extends from halfway through the circular opening towards the outer wall of box body 1 to halfway through the box body. The diameter of the circular opening is smaller than the diameter of the sample, allowing sample retrieval via the side opening and closing of the cover 3. The side opening mechanism of the cover 3 makes opening and closing more flexible, facilitating sample placement and removal. The loading assembly 4 is located inside the sample placement cavity 2 to fix the sample and ensure its stability during the laser ablation process.

[0022] Among them, such as Figure 3 As shown, the hinge assembly includes a first hinge rod 5 disposed on the housing 1 and having a hinge hole, a second hinge rod 6 disposed on the cover 3 and having a hinge hole, and a hinge hub 7 passing through the hinge holes of the first hinge rod 5 and the second hinge rod 6, thereby achieving the hinge connection between the cover 3 and the housing 1, allowing the cover 3 to open and close flexibly. Preferably, the hinge hub 7 is a rod-shaped structure that mates with the hinge hole.

[0023] The top of the lid 3 is equipped with a first magnetic clasp 30, and the top of the sample placement cavity 2 is equipped with a second magnetic clasp 31 that magnetically engages with the first magnetic clasp 30. The first magnetic clasp 30 is located on the top of the lid 3, and its position can be determined according to actual needs, such as being located at the center of the top of the lid 3 or near the edge. The first magnetic clasp 30 can be made of permanent magnet material and has strong magnetism. The position of the second magnetic clasp 31 should correspond to the first magnetic clasp 30 to ensure accurate engagement. The second magnetic clasp 31 can also be made of permanent magnet material, attracting the first magnetic clasp 30 to achieve a tight seal between the lid 3 and the sample placement cavity 2, preventing the lid 3 from accidentally opening during transportation and daily storage, which could cause the resin target to slip or even affect sample fixation. Simultaneously, the magnetic clasp design makes opening and closing the lid 3 more convenient and quick; operators only need to apply slight force to open and close the lid 3.

[0024] like Figure 4 As shown, the sample carrier assembly 4 includes a base 40 disposed at the bottom of the sample placement cavity 2, an elastic element 41 disposed on the base 40, and a stage 42 disposed on top of the elastic element 41. The elastic element 41 and the stage 42 are located inside the sample placement cavity 2. The base 40, as the basic component of the sample carrier assembly 4, is fixed to the bottom of the sample placement cavity 2. The base 40 can be made of the same material as the box body 1 to ensure the consistency and stability of the overall structure. The shape of the base 40 can be designed as circular, square, etc., to match the shape of the sample placement cavity 2. The elastic element 41 is disposed on the base 40 and has a certain degree of elasticity and cushioning performance. The elastic element 41 can be a spring, which can provide stable support force and cushioning effect. The stage 42 is used to place the sample. The surface of the stage 42 is flat and smooth, and can be made of metal or ceramic materials to ensure the stability of sample placement. The size of the stage 42 can be customized according to the size of the sample, and some positioning grooves or positioning holes can be set on the stage 42 to better fix the sample.

[0025] like Figure 5 As shown, the box body 1 is covered with a lid 10, and the inner wall of the lid 10 is provided with a sponge pad 11 to ensure that the resin target is fixed in the target box when it is closed, preventing it from being accidentally slipped and damaged during movement. In addition, a label strip 12 is affixed to the surface of the box body 1, through which basic information of the sample can be marked for easy identification.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
