[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0014] Example 1 This utility model provides a mounting device for a deuterium lamp and a tungsten lamp in a spectrometer, such as... Figures 1 to 5 As shown, the spectrometer's deuterium lamp and tungsten lamp mounting device includes a spectrometer body 1, a flip cover 2, a deuterium lamp body 3, a tungsten lamp body 4, and mounting components. The spectrometer body 1 provides a carrier for light emission and spectral analysis; the flip cover 2 prevents dust and impurities from entering the spectrometer body 1 and damaging the light source components; the deuterium lamp body 3 and the tungsten lamp body 4 are mainly used to emit light of corresponding wavelengths for spectral analysis; the mounting components include a base 5, a movable block 6, a magnetic block 7, an elastic element 8, a positioning rod 9, and a toggle block 10. There are two sets of bases 5, which are respectively installed at the bottom of the deuterium lamp body 3 and the tungsten lamp body 4. Two movable blocks 6 are also slidably installed inside the spectrometer body 1, and a magnetic block 7 is embedded inside each movable block 6; an elastic element 8 is symmetrically connected inside each movable block 6, and the other end of the elastic element 8 is connected to a positioning rod 9. The toggle block 10 is fixedly connected to the outer surface of the positioning rod 9.

[0015] In this embodiment, the base 5 is also symmetrically provided with positioning grooves 11, and the positioning rod 9 can be inserted into the positioning grooves 11; the spectrometer body 1 is also integrally formed with a protrusion 61, and the movable block 6 is provided with a sliding groove corresponding to the outer surface of the protrusion 61.

[0016] By installing the base 5 directly above the movable block 6, the magnetic block 7 attracts the base 5, and the positioning rod 9 is symmetrically inserted into the positioning groove 11 opened on the base 5, so that the deuterium lamp body 3 and the tungsten lamp body 4 can be fixedly installed on the top of the movable block 6, which is convenient to operate.

[0017] In use, the operator places the base 5 directly above the movable block 6, then moves the two sets of actuating blocks 10 on the movable block 6, causing the two positioning rods 9 to move closer to each other and compress the elastic element 8. The base 5 is then fitted onto the outer surface of the movable block 6, causing the magnetic block 7 to firmly hold the base 5. The two sets of actuating blocks 10 are then released, and the compressed elastic element 8 releases its elastic potential energy, pushing the connected positioning rod 9 to move in the opposite direction, thereby inserting the positioning rod 9 into the positioning groove 11. This allows the deuterium lamp body 3 and the tungsten lamp body 4 to be fixedly installed on the movable block 6, achieving quick installation of the deuterium lamp body 3 and the tungsten lamp body 4. The operation is simple, and even non-professionals can easily master it. At the same time, the disassembly process is the reverse of the above steps, which also facilitates subsequent maintenance and replacement work, reducing maintenance costs and time costs.

[0018] To improve the practical performance of this device, such as Figures 1 to 5 As shown, the lifting assembly of the deuterium lamp and tungsten lamp mounting device of the spectrometer includes a drive component 12, a lead screw 13, a slider 14, and a lower sliding block 15. The drive component 12 is fixedly installed inside the spectrometer body 1, and the lead screw 13 is connected to the drive component 12. There are two sets of sliders 14 arranged symmetrically. The spectrometer body 1 also has a guide groove inside. Both sliders 14 slide against the inner wall of the guide groove. Both sliders 14 are installed on the outer surface of the lead screw 13 by threaded connection. Each slider 14 has a lower sliding block 15 fixedly connected to its top.

[0019] By energizing the drive unit 12 and causing the lead screw 13 to rotate, the lead screw 13 rotates and drives the two sliders 14 to move closer to each other through the threaded connection. This causes the two lower sliding blocks 15 to move closer to each other. When the inclined surfaces of the lower sliding blocks 15 and the movable blocks 6 come into contact with each other, the two movable blocks 6 are lifted up as the two lower sliding blocks 15 continue to move closer. This changes the position and height of the deuterium lamp body 3 and the tungsten lamp body 4, allowing users to flexibly adjust the light source height of the deuterium lamp body 3 and the tungsten lamp body 4 according to different experimental needs. This makes it suitable for various experimental scenarios and sample detection and analysis, enhancing the versatility of the spectrometer.

[0020] Support plates 16 are fixedly connected to the outer surfaces of the two movable blocks 6. Guide rods 17 are symmetrically fixedly connected to the top of the support plates 16. The top of the guide rods 17 can pass through the housing of the spectrometer body 1. An elastic element 2 18 is movably sleeved on the outer surface of each guide rod 17. The bottom end of the elastic element 2 18 is connected to the support plate 16, and the top end of the elastic element 2 18 is fixedly connected to the inner wall of the spectrometer body 1.

[0021] Under the action of the guide rod 17, the movable block 6 can move vertically. As the lower sliding block 15 pushes the movable block 6 upward, the elastic element 18 is compressed and deformed. When the two sets of lower sliding blocks 15 move away from each other... Figure 3 When the position shown is reached, the compressed elastic element 2 18 can push the movable block 6 down and return it to its original installation position. This not only raises the illumination height of the deuterium lamp body 3 and the tungsten lamp body 4, but also ensures that the movable block 6 can automatically return to its initial state by utilizing the elastic restoring force of the elastic element 2 18. This provides users with a convenient operating experience and an automatic reset effect.

[0022] Specifically, both elastic element 18 and elastic element 218 are springs; the driving element 12 is specifically a driving motor, the lead screw 13 is a bidirectional threaded rod, and the lead screw 13 is connected to the output shaft of the driving element 12 by a flat key.

[0023] Working principle: In actual use, the operator opens the flip cover 2 of the spectrometer body 1, then places the base 5 of the deuterium lamp body 3 and the tungsten lamp body 4 directly above the movable block 6. Then, the operator pushes the two actuating blocks 10 on each set of movable blocks 6, so that the two positioning rods 9 inside the movable block 6 come closer to each other and squeeze the elastic element 8. Then, the base 5 is fitted onto the outer surface of the movable block 6, so that the magnetic block 7 tightly attracts the base 5. Then, the two sets of actuating blocks 10 are released, and the compressed elastic element 8 releases its elastic potential energy to push the connected positioning rod 9 to move in the opposite direction, thereby inserting the positioning rod 9 into the positioning groove 11. This allows the deuterium lamp body 3 and the tungsten lamp body 4 to be fixedly installed on the movable block 6, realizing the quick installation of the deuterium lamp body 3 and the tungsten lamp body 4. The operation is simple and even non-professionals can easily get started. At the same time, the disassembly process is the reverse of the above steps, which also facilitates subsequent maintenance and replacement work, reducing maintenance costs and time costs. With the lifting assembly in place, staff can power the drive unit 12 to rotate the lead screw 13 according to actual experimental needs. When the lead screw 13 rotates, it drives the two lower sliding blocks 15 to move closer to each other through the threaded connection. This causes the lower sliding blocks 15 and the inclined part of the movable block 6 to come into contact with each other, thereby lifting the movable block 6 and sliding it upwards in the vertical direction. This allows users to flexibly adjust the light source height of the deuterium lamp body 3 and the tungsten lamp body 4 according to different experimental needs. It is applicable to a variety of experimental scenarios and sample detection and analysis, enhancing the versatility of the spectrometer. After the position and height of the deuterium lamp body 3 and the tungsten lamp body 4 are adjusted, the flip cover 2 can be closed, and the control button 101 on the spectrometer body 1 can be pressed to start the spectrometer body 1.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
