Description

Technical Field

[0001] This utility model relates to the field of atomic absorption spectrophotometer technology, and in particular to an atomic absorption spectrophotometer. Background Technology

[0002] An atomic absorption spectrophotometer, also known as an atomic absorption spectrophotometer or atomic absorption spectrometer, is an analytical instrument based on atomic absorption spectroscopy technology. The working principle of an atomic absorption spectrophotometer is to use a light source to emit characteristic spectral radiation of the element to be measured. This radiation is absorbed by the ground-state atoms of the element to be measured in the sample vapor after passing through an atomizer. The degree of absorption is proportional to the content of the element to be measured. By measuring the amount of characteristic radiation absorbed, the content of the element to be measured can be determined.

[0003] In the use of atomic absorption spectrophotometers, the flasks used to hold samples are usually placed directly on the operating table. Due to possible collisions, vibrations, or table tilting during operation, the flasks are prone to tipping over. This not only leads to spillage of the solution and waste of experimental materials, but also may affect the experimental environment due to solution leakage, and even cause safety hazards. To address these issues, we propose an atomic absorption spectrophotometer. Utility Model Content

[0004] The purpose of this invention is to provide an atomic absorption spectrophotometer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An atomic absorption spectrophotometer includes a spectrophotometer body. A support shell is rotatably connected to the outer surface of the spectrophotometer body via a hinge. A plurality of sliding cylinders are fixedly connected to the inner bottom wall of the support shell. A sliding column is fixedly connected to the inner side wall of each sliding cylinder. A conical rubber block is fixedly connected to the outer surface of each sliding column. A bottle holder is fixedly connected to the upper surface of each conical rubber block. A first elastic element is fixedly connected to the bottom surface of each conical rubber block. The bottom surface of each first elastic element is fixedly connected to the upper surface of each sliding cylinder. A plurality of negative pressure holes are opened on the upper surface of the support shell. A plurality of annular sealing gaskets are fixedly connected to the upper surface of the support shell. A fan is fixedly connected to the bottom surface of the support shell.

[0007] In a further embodiment, a support plate is fixedly connected to the front of the photometer body, and a rubber pad is fixedly connected to the upper surface of the support plate.

[0008] In a further embodiment, a handrail is fixedly connected to the bottom surface of the holder, and multiple air inlet slots are provided on the bottom surface of each bottle holder.

[0009] In a further embodiment, two limiting frames are fixedly connected to the front of the photometer body, and two connecting frames are fixedly connected to the outer surface of the support shell.

[0010] In a further embodiment, a limiting plate is slidably connected to the inner sidewall of each connecting frame, and a push plate is fixedly connected to the bottom surface of each limiting plate.

[0011] In a further embodiment, a second elastic element is fixedly connected to the outer surface of each limiting plate, and the outer surface of each second elastic element is fixedly connected to the inner sidewall of each connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses negative pressure generated by a fan to firmly fix the flask. At the same time, the flask holder drops due to gravity, causing the conical rubber block to separate from the negative pressure hole. This, combined with the annular sealing gasket, achieves a seal, preventing the flask from tilting or falling due to collisions or vibrations. When no flask is placed above the negative pressure hole, the elastic force of the first elastic element will push the conical rubber block to block the negative pressure hole, ensuring the high efficiency of the negative pressure system and preventing insufficient overall negative pressure due to leakage from unused negative pressure holes. This ensures that the placed flask can be stably fixed. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5In this utility model, an atomic absorption spectrophotometer includes a spectrophotometer body 1. A support shell 2 is rotatably connected to the outer surface of the spectrophotometer body 1 via a hinge. Multiple sliding cylinders 3 are fixedly connected to the inner bottom wall of the support shell 2. A sliding column 4 is fixedly connected to the inner side wall of each sliding cylinder 3. A conical rubber block 5 is fixedly connected to the outer surface of each sliding column 4. A bottle holder 6 is fixedly connected to the upper surface of each conical rubber block 5. A first elastic element 7 is fixedly connected to the bottom surface of each conical rubber block 5. The bottom surface of each first elastic element 7 is fixedly connected to the upper surface of each sliding cylinder 3. The upper surface of the support shell 2 has a... Multiple negative pressure holes 8 are provided. Multiple annular sealing gaskets 9 are fixedly connected to the upper surface of the support shell 2. A blower 10 is fixedly connected to the bottom surface of the support shell 2. By placing the beaker on the bottle holder 6 and the annular sealing gaskets 9, a sealed space can be formed between the bottom surface of the beaker, the inner wall of the annular sealing gaskets 9 and the interior of the support shell 2. The negative pressure generated by the blower 10 adsorbs the bottom of the flask, thereby achieving the effect of fixing the beaker. The first elastic element 7 applies force to the conical rubber block 5 and the bottle holder 6, causing the conical rubber block 5 to block the negative pressure holes 8, thus preventing insufficient overall negative pressure due to leakage from unused negative pressure holes 8.

[0024] A support plate 11 is fixedly connected to the front of the photometer body 1, and a rubber pad 12 is fixedly connected to the upper surface of the support plate 11. A handrail 13 is fixedly connected to the bottom surface of the support shell 2. Multiple air inlet slots 14 are provided on the bottom surface of each bottle holder 6. By setting the support plate 11 and the rubber pad 12, the support shell 2 can be supported. By setting the air inlet slots 14, the bottle holder 6 is prevented from blocking the negative pressure hole 8.

[0025] Two limiting frames 15 are fixedly connected to the front of the photometer body 1, and two connecting frames 16 are fixedly connected to the outer surface of the support shell 2. A limiting plate 17 is slidably connected to the inner side wall of each connecting frame 16. A push plate 19 is fixedly connected to the bottom surface of each limiting plate 17. A second elastic member 18 is fixedly connected to the outer surface of each limiting plate 17. The outer surface of each second elastic member 18 is fixedly connected to the inner side wall of each connecting frame 16. By setting the second elastic member 18, a force can be continuously applied to the limiting plate 17 to prevent the limiting plate 17 from moving at will. Inserting the limiting plate 17 into the limiting frame 15 can limit and store the support shell 2, reducing the space occupied when not in use.

[0026] The working principle of this utility model is as follows:

[0027] When using this device, move the two push plates 19 to move the limiting plate 17 inward, so that the limiting plate 17 is separated from the limiting frame 15. Rotate the support shell 2 to place it on the support plate 11. Turn on the fan 10. The rotation of the fan 10 generates negative pressure, which puts the beaker or flask on the bottle holder 6. The bottle holder 6 will fall due to the weight of the flask and pressurize the first elastic element 7, so that the conical rubber block 5 separates from the negative pressure hole 8 and the flask contacts the annular sealing gasket 9, isolating the bottom of the flask from the outside. Thus, the negative pressure is used to fix the flask on the support shell 2 to prevent the flask from tilting or falling. If no flask is placed above the negative pressure hole 8, the elastic force of the first elastic element 7 will continuously apply force to the conical rubber block 5, so that the conical rubber block 5 blocks the negative pressure hole 8.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
