Technical Field

[0001] The utility model relates to the technical field of sample detection racks, in particular to a sample detection rack based on acid-removed samples. Background Art

[0002] In the fields of chemical analysis and materials testing, sample processing and testing often require an acid-removal step. Acid removal, a process that removes excess acid from a sample through heating or other methods, is commonly used for sample pretreatment, particularly in the chemical analysis of samples such as metals, minerals, and soil. To obtain accurate sample content, samples after acid removal often require further testing. During this process, a sample holder supports, secures, and protects the sample, facilitating subsequent testing.

[0003] However, in actual use, the traditional design has poor stability when removing or installing the tray. The tray is usually simply placed on top of the sample rack body, which is prone to sliding or displacement during operation, and the stability of the tray during transportation or use cannot be ensured.

[0027] Example 1:

[0028] A sample rack based on acid-dried sample detection, comprising a sample rack body 1, with locking mechanisms 7 provided on both sides of the sample rack body 1, the locking mechanisms 7 comprising a mounting plate 701, a locking plate 702, an adjusting rod 703, a locking groove 704, a locking block 705, a reset spring 706, a fixing plate 707 and a slot 708. A tray 3 is provided on the top of the sample rack body 1, a plurality of sample bodies 4 are inserted in the middle of the tray 3, the bottom ends of the two mounting plates 701 are fixedly connected to the fixing plates 707, the inner sides of the two fixing plates 707 are fixedly connected to the reset springs 706, the middle parts of the two mounting plates 701 are slidably connected to the locking plates 702, the middle parts of the two locking plates 702 are rotatably connected to the adjusting rod 703, the rotation connection between the adjusting rod 703 and the locking plate 702 has damping, and non-human rotation itself will not occur. Rotate, one end of the two adjusting rods 703 passes through the two mounting plates 701 respectively, and is fixedly connected with a locking block 705. The front and back of the sample rack body 1 are fixedly connected to the two limit plates 5. The front and back of the mounting frame 204 are slidably connected to the inner sides of the four limit plates 5 respectively. The tray 3 is made of stainless steel, and the limit plates 5 can provide a limit for the mounting frame 204. The two mounting plates 701 are fixedly connected to the two side walls of the sample rack body 1. The two side walls of the mounting frame 204 are provided with slots 708. One end of the two locking plates 702 is respectively inserted into the inner walls of the two slots 708. The two locking blocks 705 match the sizes of the two locking grooves 704. One end of the two return springs 706 is fixedly connected to the outer side of the mounting plate 701. The front and back of the mounting frame 204 are fixedly connected with handles 6.

[0029] During operation, when the user needs to take out all the sample bodies 4 on the tray 3, the user can pull the two adjusting rods 703, and the two adjusting rods 703 respectively drive the two locking plates 702 away from the slots 708, and the locking block 705 at one end of the adjusting rod 703 also moves away from the locking groove 704.
