[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figures 1-8 This utility model provides a technical solution:

[0031] Example:

[0032] like Figures 1-8As shown, a sampling and storage device for a liquid chromatography-mass spectrometry analyzer includes a storage box 1. The storage box 1 has mounting plates 2 on its two opposite inner sidewalls. The mounting plates 2 are provided with vertical slide rails 6. The crossbars 3 are provided with sliders 7 that are slidably connected to the slide rails 6. The mounting plates 2 are slidably connected to multiple crossbars 3 through the sliders 7 and the slide rails 6. The crossbars 3 can slide vertically to adjust the spacing between them.

[0033] The crossbar 3 is fixed to the mounting plate 2 by a locking assembly 4. A horizontal shelf 5 is detachably connected between the two crossbars 3. The crossbar 3 has a horizontal connecting groove 8. Both ends of the shelf 5 have connecting parts 9 that are adapted to the connecting groove 8. The shelf 5 is connected to the crossbar 3 through the connecting parts 9 and the connecting groove 8. The shelf 5 has multiple test tube holes. The connecting groove 8 can be, but is not limited to, a C-shaped structure; it can also be a dovetail groove or a T-shaped groove. Relatively speaking, the C-shaped groove in this embodiment is easier to process.

[0034] like Figures 4-7 As shown, the locking assembly 4 includes a mounting rod 10, a top block 11, and a connecting plate 12. The mounting rod 10 is vertically (fixed) mounted on the mounting plate 2. The mounting rod 10 is a rectangular steel rod. The mounting rod 10 has multiple mounting holes along its vertical direction. A spring 13 is provided in the mounting hole and is coaxial with it. One end of the spring 13 is connected to a locking block 14. The locking block 14 is located in the mounting hole and its surface is flush with the opening of the mounting hole.

[0035] The connecting plate 12 (fixed) is disposed on the top surface of the crossbar 3. The connecting plate 12 is provided with a threaded hole coaxial with the mounting hole. The connecting plate 12 is connected to the screw 15 through the threaded hole. The top block 11 is disposed at one end of the screw 15 near the mounting rod 10. The top block 11 (size and shape) is adapted to the mounting hole.

[0036] 1. The mounting rod 10 and slide rail 6 are flush with the top of the mounting plate 2. A gap is provided between the top of the mounting plate 2 and the inner top of the storage box 1. The gap size is larger than the height of the crossbar 3 to facilitate the addition or removal of the crossbar 3 through the gap. 2. The mounting hole is a cylindrical hole. The top block 11 and the locking block 14 are both cylindrical structures. 3. To facilitate observation of whether the top block 11 is in place, the top block 11 is designed as a structure of two cylinders with different diameters. The diameter of the smaller end of the top block 11 is adapted to the diameter of the mounting hole. When the top block 11 is in place, the larger end of the top block 11 is in close contact with the surface of the mounting rod 10.

[0037] Working principle: The shelf 5 is horizontally installed between two crossbars 3. The number of shelf 5 can be increased or decreased by adjusting the gap between the mounting plate 2 and the top of the storage box 1, thereby improving the space utilization of the storage box 1. Simultaneously, the spacing between the shelf 5 is adjustable to accommodate test tubes of different lengths. The adjustment process for the spacing between the shelf 5 is as follows:

[0038] The shelf 5 is vertically positioned by rotating the screw 15, which causes the top block 11 to press against the locking block 14 (compressing the spring 13 during this process). This allows the top block 11 to enter the mounting hole, thus limiting the vertical movement of the crossbar 3. The horizontal movement of the crossbar 3 is limited by the slider 7 of the slide rail 6. Therefore, the crossbar 3 is locked onto the mounting plate 2 by the locking assembly 4. When the position of the shelf 5 needs adjustment, the screw 15 is rotated in the opposite direction, causing the top block 11 at the end of the screw 15 to exit the mounting hole. When both top blocks 11 on both sides of the shelf 5 have exited the mounting holes, the shelf 5 regains its vertical freedom and can then slide vertically along the slide rail 6. After sliding, the screw 15 is turned back into its corresponding mounting hole, thus re-fixing the shelf 5.

[0039] This utility model allows for adjustment of the number of storage layers inside the storage box 1 by adding or removing storage boards 5. At the same time, the spacing between the storage boards 5 is adjustable to accommodate test tubes of different lengths. The storage boards 5 can be added or removed according to actual usage to improve space utilization.

[0040] Furthermore, such as Figure 1 As shown, a mounting cavity communicating with the storage box 1 is provided on one side of the storage box 1, and a cooling module 16 for cooling the interior of the storage box 1 is provided in the mounting cavity. The cooling module 16 is prior art, and its working principle and specific structure will not be described in detail here.

[0041] Furthermore, such as Figure 8 As shown, the storage box 1 has a support plate 17 at its bottom, and casters 18 are provided at the four corners of the support plate 17. The casters 18 facilitate the movement of the storage box 1.

[0042] Furthermore, such as Figure 8 As shown, a connecting shaft 21 is rotatably connected to the bottom of the support plate 17, and a driven gear 19 is fixedly connected to the connecting shaft 21. The bottom of the support plate 17 is also provided with a rotating shaft, and a driving gear 20 is provided on the rotating shaft (here, the rotating shaft can be fixed to the support plate 17, in which case the driving gear 20 is rotatably connected to the rotating shaft through a bearing; the rotating shaft can also be rotatably connected to the support plate 17 through a bearing and a bearing seat, in which case the driving gear 20 is fixed to the rotating shaft). The driving gear 20 is connected to the driven gear 19 through a toothed belt.

[0043] The connecting shaft 21 is provided with an external thread, and a connecting sleeve 22 is connected to the connecting shaft 21 via the external thread. A cross-shaped support frame 23 is fixedly connected to the connecting sleeve 22. Support feet 24 are respectively provided on the lower sides of the four ends of the support frame 23. The upper side of the support frame 23 is connected to the support plate 17 via a telescopic limiting member 26. The telescopic limiting member 26 includes a sleeve and a connecting rod, wherein the top end of the sleeve is connected to the support rod, and the bottom end of the connecting rod is connected to the support frame 23.

[0044] One side of the storage box 1 is rotatably connected to an openable and closable door 25 via a pivot.

[0045] In use, the support frame 23 raises and lowers, driving the support legs 24 to rise and fall, thus supporting the storage box 1 at a right angle and preventing it from moving during use and transportation. The raising and lowering process of the support frame 23 is as follows: the drive gear 20 rotates, driving the driven gear 19 to rotate via a toothed belt. When the driven gear 19 rotates, it drives the connecting shaft 21 to rotate. When the connecting shaft 21 rotates, it cannot rotate due to the limiting telescopic component on the support frame 23. Furthermore, the telescopic frame is threadedly connected to the connecting shaft 21 via the connecting sleeve 22. Therefore, when the connecting shaft 21 rotates, it drives the telescopic frame to rise and fall.

[0046] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
