Description

Technical Field

[0001] This invention belongs to the field of photometer technology, and in particular relates to a spectrophotometer that is convenient for detecting gases. Background Technology

[0002] A spectrophotometer, also known as a spectrometer, is a scientific instrument that breaks down complex light into spectral lines. A spectrophotometer uses a light source that can generate multiple wavelengths. Through a series of spectroscopic devices, a light source of a specific wavelength is generated. After the light passes through the sample being tested, some of the light is absorbed. The absorbance value of the sample is calculated and thus converted into the concentration of the sample.

[0003] A spectrophotometer authorized in China (publication number CN215263116U) uses a positioning mechanism. During use, the spectrophotometer body is placed on a worktable, and the positioning mechanisms on both sides move to opposite sides of the worktable. Then, by rotating the limiting bolts, the positioning blocks are clamped onto the worktable, thus fixing the spectrophotometer body and improving its stability. This prevents the spectrophotometer from shifting due to operator error or accidental contact, facilitating practical use. However, in actual use, when the worktable is wide, the connecting rod extends beyond the connecting block and is exposed on the worktable surface. Because the connecting rod has a toothed edge, it can easily scratch the user. Furthermore, the exposed connecting rod can hinder the placement of items on the worktable. Therefore, we propose a spectrophotometer that facilitates gas detection. Utility Model Content

[0004] The purpose of this utility model is to provide a spectrophotometer that facilitates gas detection, thereby solving the existing problem: In the case of a spectrophotometer with Chinese authorized publication number CN215263116U, when the worktable is wide, the connecting rod will extend beyond the connecting block and be exposed on the worktable surface. Because there is a toothed rack on one side of the connecting rod, it is easy to scratch the user. At the same time, the connecting rod exposed on the worktable surface will prevent the staff from placing things on the worktable.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] Furthermore, a suction cup shell is fixedly connected to the bottom of the detection box, an adsorption plate is provided on the inner side of the suction cup shell, and a first telescopic rod is fixedly connected to the top of the adsorption plate. The first telescopic rod extends into the interior of the detection box and is slidably connected to the detection box.

[0008] Furthermore, a second telescopic rod is provided on the surface of the first telescopic rod, and a connecting post is provided on the surface of the second telescopic rod. The top of the connecting post is fixedly connected to the photometer body.

[0012] Furthermore, two fixed stops are provided, and the two fixed stops are positioned opposite each other.

[0027] Please see Figures 1-4 As shown, this utility model is a spectrophotometer for easy gas detection, including a detection chamber 1. A sealing cover 2 is provided on the top of the detection chamber 1, and the sealing cover 2 is snapped into the detection chamber 1. A handle 3 is provided on the surface of the detection chamber 1. A rotating block 4 is provided on one side of the detection chamber 1, and a screw 12 is fixedly connected to one side of the rotating block 4. The screw 12 extends into the interior of the detection chamber 1. A slider 10 is provided on the surface of the screw 12, and a connecting rod 9 is rotatably connected to the top of the slider 10. A photometer body 6 is provided inside the detection chamber 1, and the bottom of the photometer body 6 is movably connected to the connecting rod 9. The side walls of the detection chamber 1 are fixed. The device is connected to a fixed stop bar 8 and a sliding column 11, with the sliding column 11 slidably connected to the slider 10. Through the structural design of the detection box 1, sealing cover 2, and handle 3, this invention achieves the function of conveniently carrying the photometer body 6, improving the convenience of the patent. Simultaneously, through the structural design of the rotating block 4, screw 12, slider 10, sliding column 11, and connecting rod 9, it achieves the function of lifting and lowering the photometer body 6, thus facilitating the use of the photometer body 6 and improving the practicality of the patent. A suction cup shell 5 is fixedly connected to the bottom of the detection box 1, and an adsorption plate 16 is provided on the inner side of the suction cup shell 5. The top of the adsorption plate 16... A first telescopic rod 13 is fixedly connected to the detector 1, extending into the interior of the detector 1 and slidably connected to it. A second telescopic rod 14 is provided on the surface of the first telescopic rod 13, and a connecting post 15 is provided on the surface of the second telescopic rod 14. The top of the connecting post 15 is fixedly connected to the photometer body 6. A second adjusting plate 17 is fixedly connected to the top of the first telescopic rod 13, and both the second adjusting plate 17 and the first telescopic rod 13 are slidably connected to the second telescopic rod 14. A first adjusting plate 7 is fixedly connected to the top of the second telescopic rod 14. The first adjusting plate 7 and the second telescopic rod 14 are slidably connected to each other. All rods 14 are slidably connected to the connecting column 15. Through the structural design of suction cup shell 5, suction plate 16, first telescopic rod 13, second telescopic rod 14, connecting column 15, first adjusting plate 7 and second adjusting plate 17, this utility model realizes the function of fixing the detection box 1 by adsorbing the worktable through the suction plate 16, which improves the stability of the patent during use. The screw 12 is threadedly connected to the slider 10, and the two ends of the screw 12 have opposite thread directions. There are two fixing bars 8, and the two fixing bars 8 are positioned opposite each other. There are four suction plates 16, and all four suction plates 16 are made of elastic rubber.

[0028] A specific application of this embodiment is as follows: In actual use, first place the detection box 1 on the workbench surface, open the sealing cover 2, and then rotate the rotating block 4. The rotating block 4 drives the screw 12 to rotate, and the screw 12 drives the slider 10 to move. Because the threads at both ends of the screw 12 are opposite, the two sliders 10 move in opposite directions. By moving the two sliders 10 to both sides, the connecting rod 9 is moved. At this time, the connecting rod 9 will push the photometer body 6 to move upward. When the photometer body 6 moves upward, it will drive the connecting column 15. The connecting column 15 will drive the second telescopic rod 14. The second telescopic rod 14 will drive the first telescopic rod 13. The first telescopic rod 13 will pull the adsorption plate 16, so that the adsorption... The center of the plate 16 is raised upwards, allowing the adsorption plate 16 to adhere to the surface of the workbench, thus preventing it from moving during use. After use, the rotating block 4 is rotated in the opposite direction, causing the screw 12 to reverse and the two sliders 10 to move inwards. This causes the photometer body 6 to move downwards via the connecting rod 9. As the photometer body 6 moves downwards, the connecting column 15 moves downwards, causing the second telescopic rod 14 to retract into the connecting column 15 and the first telescopic rod 13 to retract into the second telescopic rod 14. When the bottom of the photometer body 6 moves to the top of the fixed stop bar 8, the first telescopic rod 13 pushes the adsorption plate 16, thereby releasing the adsorption plate 16 from the surface of the workbench.
