[0002] An atomic absorption spectrophotometer is an instrument that analyzes metal elements based on the absorption of characteristic radiation by a substance's ground-state atomic vapor. It can sensitively and reliably determine trace elements. During the testing process, standard element solutions of varying concentrations must be prepared, as well as sample solutions to be tested. Traditionally, this method involves engineers manually preparing solutions using handheld sample tubes. Each preparation represents a new operation, requiring high levels of attention and technical expertise. The process is cumbersome and inefficient.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a sample tube storage device for an atomic absorption spectrophotometer, comprising two vertical plates, a panel, a bottom plate and a plurality of liquid level indicator lines, wherein the two ends of the panel are connected to the tops of the two vertical plates, and the two ends of the bottom plate are connected to the bottoms of the two vertical plates, and the panel and the bottom plate are provided with multiple rows of corresponding tube clamping holes, and the multiple liquid level indicator lines are arranged in a one-to-one correspondence in front of the multiple rows of tube clamping holes, and the two ends of each of the liquid level indicator lines can be mounted on the two vertical plates in a liftable manner to adjust the indication position.

[0006] Based on the above, the liquid level indicator line includes a steel wire, a wiring block connected to both ends of the steel wire, and a locking screw threadedly connected to the outer end of each wiring block. An end cap is provided at the outer end of the locking screw, and a lifting channel is opened on the vertical plate corresponding to the locking screw. The end cap and the wiring block are clamped on both sides of the vertical plate.

[0007] Based on the above, the vertical plate is provided with a shallow guide groove on the outside of each lifting channel, and the shallow guide groove clamps the end cap to guide the lifting direction of the end cap.

[0008] Based on the above, scale lines are respectively provided on the inner side of the vertical plate next to each of the lifting channels, and pointers are provided on the wiring block corresponding to the scale lines.

[0010] The present invention has substantial features and progress over the prior art. Specifically, the present invention provides the tube clamping holes on the panel and the bottom plate, so that sample tubes can be placed thereon. The liquid level indicator line can indicate a row of sample tubes at a time, making it convenient for engineers to control the liquid level of each sample tube to be equal, thereby facilitating the preparation of solutions of different concentrations. The present invention has the advantages of assisting in the preparation of solutions of different concentrations, simplifying the liquid preparation operation, and improving the liquid preparation efficiency.

[0017] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0018] like Figure 1-4As shown, a sample tube storage device for an atomic absorption spectrophotometer includes two vertical plates 1, a panel 2, a bottom plate 3, and four groups of liquid level indicator lines. The two ends of the panel 2 are connected to the tops of the two vertical plates 1, and the two ends of the bottom plate 3 are connected to the bottoms of the two vertical plates 1. Four rows of corresponding tube clamping holes 4 are opened on the panel 2 and the bottom plate 3. An elastic rubber ring 12 is provided on the inner circle of each tube clamping hole 4. The upper and lower elastic rubber rings 12 can clamp the sample tube to keep the sample tube in an upright state; the four groups of liquid level indicator lines are arranged in a one-to-one correspondence on the front sides of the four rows of tube clamping holes 4, and the two ends of each liquid level indicator line can be lifted and lowered on the two vertical plates 1 to adjust the indication position.

[0019] Specifically, the liquid level indicator line includes a steel wire 5, a terminal block 6 connected to both ends of the steel wire 5, and a locking screw 7 threadedly connected to the outer end of each terminal block 6, an end cap 8 is provided at the outer end of the locking screw 7, and the vertical plate 1 is provided with a lifting channel 9 corresponding to the locking screw 7. The end cap 8 and the terminal block 6 are clamped on both sides of the vertical plate 1, and scale lines are respectively provided on the inner side of the vertical plate 1 next to each lifting channel 9, and a pointer 11 is provided on the terminal block 6 corresponding to the scale line; by rotating the end cap 8, the end cap 8 and the terminal block 6 can clamp or loosen the vertical plate 1, thereby facilitating the adjustment of the height of the steel wire 5 so that the steel wire 5 indicates the target liquid level.

[0020] In order to prevent the steel wire 5 from being deflected, the vertical plate 1 is provided with a shallow guide groove 10 on the outside of each lifting channel 9. The shallow guide groove 10 clamps the end cap 8 to guide the lifting direction of the end cap 8.

[0021] During specific use, multiple sample tubes are placed in the tube clamping hole 4. When preparing solutions of different concentrations for the sample tubes in the same row, the height of the liquid level indicator line is first adjusted so that the steel wire 5 indicates the required liquid level. The engineer uses a pipette to drip different amounts of sample and solvent into each sample tube so that the final liquid level of each sample tube reaches the position of the steel wire 5, completing the preparation of solutions of different concentrations.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
