Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, specifically a spectrometer element lamp control frame. Background Technology

[0002] With the development of atomic absorption analysis, the requirements for rapid and accurate sample analysis are becoming increasingly stringent. However, because the light source used in atomic absorption analysis, namely the hollow cathode lamp, needs to be preheated for a sufficient amount of time to ensure the accuracy and reliability of the analytical data, it is essential to ensure that the corresponding hollow cathode lamp is preheated before performing atomic absorption analysis. Preheating the hollow cathode lamp generally takes at least half an hour, which significantly extends the analysis time.

[0003] Currently, domestic lamp preheating methods only allow for sequential preheating of the next element lamp, which greatly limits the flexibility and breadth of analysis. Furthermore, if element lamps are not used for extended periods, they need to be turned on and run for about half an hour periodically to ensure their stability and extend their lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a spectrometer element lamp control frame to solve the problems mentioned in the background art.

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

[0006] A spectrometer element lamp control frame includes a fixed support rod, a fixed plate fixedly connected to the top of the fixed support rod, a sliding bearing fixedly connected to one side of the fixed plate, a sliding telescopic cylinder slidably connected inside the sliding bearing, an element lamp slidably mounted inside the sliding telescopic cylinder, a clamping assembly for fixing and holding the element lamp installed at one end of the sliding telescopic cylinder through the fixed plate, a stop fixedly connected to the other end of the sliding telescopic cylinder, a spring installed between the stop and the fixed plate, a sliding mounting cylinder fixedly connected to the side of the stop away from the sliding telescopic cylinder, a fixed mounting cylinder slidably connected to the outer wall of the sliding mounting cylinder, an externally threaded cylinder provided on the outer wall of the fixed mounting cylinder, a nut threaded onto the external thread, a top tube fixedly connected to the nut, the top tube cooperating with the stop, a concave lens installed inside the fixed mounting cylinder, and a convex lens installed inside the sliding mounting cylinder.

[0007] As a further embodiment of this utility model, a fixed mounting base is fixedly connected to the bottom of the fixed support rod.

[0008] As a further embodiment of this utility model: a positioning clamp tube is provided at the end of the fixed mounting cylinder away from the sliding mounting cylinder, and the positioning clamp tube is fixedly connected to the light output port of the spectrometer.

[0009] As a further embodiment of this utility model: the clamping assembly includes a set of fixed clamping seats fixedly connected to the sliding telescopic cylinder, the top of the fixed clamping seats is provided with a rotating clamping buckle, and the fixed clamping seats and one side of the rotating clamping buckle are rotatably connected by a hinge.

[0010] As a further embodiment of this utility model: a fixed seat is fixedly connected to the other side of the fixed clamping seat and the rotating clamping buckle; a clamping bolt is fixedly connected to one set of fixed seats; a slot is provided in the other set of fixed seats; and the clamping bolt passes through the slot and is threadedly connected to a clamping screw.

[0011] As a further improvement of this utility model, anti-slip friction rings are fixedly installed on the inner walls of the fixed clamping seat and the rotating clamping buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model supports the quick replacement and fixing of multiple element lamps through the adjustable clamping components and sliding telescopic cylinder design. In addition, this utility model adopts a combination design of convex lens and concave lens, and the lens spacing can be adjusted by turning the nut to achieve precise control of the beam focusing effect. The beam can be flexibly adjusted according to the characteristics of different element lamps, improving the signal stability and detection sensitivity of the spectrometer. At the same time, by focusing the energy, the time required by the traditional sequential preheating method is reduced, significantly improving the analysis efficiency.

[0013] In summary, this invention is particularly suitable for high-throughput atomic absorption spectrometry analysis in fields such as laboratories, industrial testing, and environmental monitoring. It can significantly shorten the sample testing cycle and reduce the maintenance cost of element lamps, thus possessing high practicality and economy. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] See Figures 1-4 In this embodiment of the present invention, a spectrometer element lamp control frame includes a fixed support rod 1, a fixed plate 3 fixedly connected to the top of the fixed support rod 1, a sliding bearing 4 fixedly connected to one side of the fixed plate 3, a sliding telescopic cylinder 5 slidably connected inside the sliding bearing 4, an element lamp 6 slidably installed inside the sliding telescopic cylinder 5, one end of the sliding telescopic cylinder 5 passing through the fixed plate 3 and having a clamping component for fixing and holding the element lamp 6 installed thereon, the other end of the sliding telescopic cylinder 5 fixedly connected to a stop block 14, a spring 16 installed between the stop block 14 and the fixed plate 3, a sliding mounting cylinder 15 fixedly connected to the side of the stop block 14 away from the sliding telescopic cylinder 5, a fixed mounting cylinder 17 slidably connected to the outer wall of the sliding mounting cylinder 15, an external thread 18 cylinder provided on the outer wall of the fixed mounting cylinder 17, a nut 19 threadedly connected to the external thread 18, a top tube 20 fixedly connected to the nut 19, the top tube 20 cooperating with the stop block 14, a concave lens 22 installed inside the fixed mounting cylinder 17, and a convex lens 23 installed inside the sliding mounting cylinder 15;

[0021] During installation, the clamping assembly is first opened, and the light-emitting end of the element lamp 6 is inserted into the sliding telescopic cylinder 5. Then, the tail of the element lamp 6 is fixedly clamped by the clamping assembly. When the equipment is running, the light emitted by the element lamp 6 is first refracted by the convex lens 23 and then the light beam is directed to the concave lens 22, which refracts and contracts the refracted light again, thereby converging the light beam to form a more focused light beam, thus achieving the concentration of light energy.

[0022] Then, when it is necessary to adjust the light, the nut 19 can be turned. The nut 19, through its threaded connection with the external thread 18, drives the top tube 20 to rise and fall. The top tube 20 pushes the stop block 14, thereby causing the fixed mounting cylinder 17 and the sliding mounting cylinder 15 to slide and extend, thereby adjusting the distance between the concave lens 22 and the convex lens 23, and thus adjusting the distance between the focal points of the concave lens 22 and the convex lens 23. The smaller the distance between the focal points of the concave lens 22 and the convex lens 23, the stronger the beam-gathering effect of the convex lens 23, the thinner the beam, and the stronger the energy-concentrating effect. Conversely, the larger the distance between the focal points of the concave lens 22 and the convex lens 23, the weaker the beam-gathering effect of the convex lens 23, the thicker the beam, and the weaker the energy-concentrating effect.

[0023] In one instance of this embodiment, please refer to Figures 1-4 The bottom of the fixed support rod 1 is fixedly connected to a fixed mounting base 2, and the present invention is fixedly installed into the spectrometer by the fixed mounting base 2.

[0024] In one instance of this embodiment, please refer to Figures 1-4 The fixed mounting cylinder 17 is provided with a positioning tube 21 at the end away from the sliding mounting cylinder 15. The positioning tube 21 is fixedly connected to the light output port of the spectrometer. This utility model achieves a stable connection between the fixed mounting cylinder 17 and the light output port of the spectrometer by setting the positioning tube 21.

[0025] In one instance of this embodiment, please refer to Figures 1-4 The clamping assembly includes a set of fixed clamping seats 7 fixedly connected to the sliding telescopic cylinder 5. The top of the fixed clamping seat 7 is provided with a rotating clamping buckle 8. The fixed clamping seat 7 and the rotating clamping buckle 8 are rotatably connected on one side by a hinge. The other side of the fixed clamping seat 7 and the rotating clamping buckle 8 is fixedly connected with a fixed seat 9. A clamping bolt 10 is fixedly connected to one set of fixed seats 9. A slot 11 is provided in the other set of fixed seats 9. The clamping bolt 10 passes through the slot 11 and is threadedly connected to a clamping screw cylinder 12. Anti-slip friction rings 13 are fixedly installed on the inner walls of the fixed clamping seat 7 and the rotating clamping buckle 8.

[0026] The clamping assembly first rotates to open the rotating clamping buckle 8 and places the element lamp 6 into the fixed clamping seat 7. Then, it rotates to close the rotating clamping buckle 8. At this time, the clamping bolt 10 rotates and engages in the slot 11. Then, the clamping screw 12 is tightened onto the clamping bolt 10. The clamping screw 12 then securely connects the fixed clamping seat 7 and the rotating clamping buckle 8. The element lamp 6 is then securely clamped by the fixed clamping seat 7 and the rotating clamping buckle 8. At the same time, the anti-slip friction ring 13 provides anti-slip and stable clamping between the element lamp 6 and the fixed clamping seat 7 and the rotating clamping buckle 8.
