Description

Technical Field

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

[0002] Atomic absorption spectrometry, also known as atomic absorption spectrophotometry, is a method of elemental analysis based on the absorption of characteristic radiation by ground-state atomic vapors. It can sensitively and reliably determine trace or ultra-trace elements and is now widely used in various fields such as metallurgy, geology, mining, petroleum, light industry, agriculture, medicine, health, food, and environmental monitoring. Moreover, it has become a standard analytical method in many fields.

[0003] An atomic absorption spectrophotometer mainly consists of four parts: a light source, an atomizer, a monochromator, and a detector. In existing atomic absorption spectrophotometers, the height of the detector is fixed during use, and it cannot be adjusted as needed during experiments, making operation inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the height cannot be adjusted as needed during experiments, thus making operation inconvenient. This invention provides an atomic absorption spectrophotometer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design an atomic absorption spectrophotometer, including a photometer body, on which a groove is formed. A first mounting plate is slidably connected to the groove. A detection mechanism is connected to the upper end of the first mounting plate. A threaded sleeve is passed through the first mounting plate. A second mounting plate is fixedly connected inside the groove. A servo motor is fixedly connected to the bottom end of the second mounting plate. The output end of the servo motor passes through the second mounting plate and is fixedly connected to a threaded rod that drives the threaded sleeve to move vertically.

[0006] Preferably, the threaded sleeve and the first mounting plate are an integral structure.

[0007] Preferably, a lubrication mechanism for lubricating the threaded rod is connected inside the groove. The lubrication mechanism includes a support frame, which is fixedly connected to the groove. A night-storage tank is fixedly connected to the support frame. A connecting pipe is connected to one bottom side of the night-storage tank. A hollow annular tube is connected to one end of the connecting pipe. A through hole is opened on the inner wall of the hollow annular tube. An applicator ring is fixedly connected to the inner wall of the hollow annular tube. The applicator ring passes through the threaded rod. A booster pump is fixedly connected to the support frame. The outlet end of the booster pump is connected to the night-storage tank through a one-way pipe.

[0008] Preferably, the through holes are provided in a plurality of them and are evenly distributed along the axis of the hollow annular tube.

[0009] Preferably, the application ring is a sponge pad.

[0010] Preferably, a leak-proof cover is fixedly connected to the upper end of the threaded sleeve.

[0011] The atomic absorption spectrophotometer proposed in this invention has the following advantages: After the servo motor is powered on, it drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to move in the vertical direction. The threaded sleeve drives the first mounting plate to move, and the first mounting plate drives the detection mechanism to move in the vertical direction. The height of the detection mechanism can be adjusted according to the experimental needs, which facilitates operation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1: Refer to Figure 1-3An atomic absorption spectrophotometer includes a photometer body 1, a groove 2 on the photometer body 1, a first mounting plate 3 slidably connected to the groove 2, a detection mechanism 4 connected to the upper end of the first mounting plate 3, a threaded sleeve 5 penetrating the first mounting plate 3, the threaded sleeve 5 and the first mounting plate 3 being an integral structure, a second mounting plate 6 fixedly connected inside the groove 2, a servo motor 7 fixedly connected to the bottom end of the second mounting plate 6, the output end of the servo motor 7 passing through the second mounting plate 6 and fixedly connected to a threaded rod 8 that drives the threaded sleeve 5 to move in the vertical direction.

[0016] Work process: After the servo motor 7 is powered on and started, it drives the threaded rod 8 to rotate. After the threaded rod 8 rotates, the threaded sleeve 5 moves in the vertical direction. The threaded sleeve 5 drives the first mounting plate 3 to move. The first mounting plate 3 moves smoothly under the guide limit of the slide groove 2. The first mounting plate 3 drives the detection mechanism 4 to move in the vertical direction. The height of the detection mechanism 4 can be adjusted according to the experimental needs, which is convenient for operation.

[0017] Example 2: Refer to Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a lubrication mechanism 9 for lubricating the threaded rod 8 is connected inside the slide opening 2. The lubrication mechanism 9 includes a support frame 91, which is fixedly connected to the slide opening 2. A night storage tank 92 is fixedly connected to the support frame 91. A connecting pipe 93 is connected to one bottom end of the night storage tank 92. A hollow annular tube 94 is connected to one end of the connecting pipe 93. A through hole 95 is opened on the inner wall of the hollow annular tube 94. Several through holes 95 are provided and are evenly distributed along the axis of the hollow annular tube 94. A coating ring 96 is fixedly connected to the inner wall of the hollow annular tube 94. The coating ring 96 is a sponge pad. The threaded rod 8 passes through the coating ring 96. A booster pump 97 is fixedly connected to the support frame 91. The outlet end of the booster pump 97 is connected to the night storage tank 92 through a one-way pipe 98. A leak-proof cover 99 is fixedly connected to the upper end of the threaded sleeve 5. The booster pump 97 is started at set intervals. After the booster pump 97 has been working for a set time, a set amount of gas is introduced into the storage tank 92 through the one-way pipe 98. After the gas is introduced into the storage tank 92, the pressure inside the storage tank 92 is increased. The lubricant in the storage tank 92 is introduced into the hollow annular pipe 94 through the connecting pipe 93. The lubricant in the hollow annular pipe 94 passes through the through hole 95 and the coating ring 96. The coating ring 96 applies the lubricant to the threaded rod 8 to prevent jamming between the threaded rod 8 and the threaded sleeve 5. The lubricant on the threaded rod 8 flows downward under its own weight. The leak-proof cover 99 limits the upper end of the threaded sleeve 5 to prevent the lubricant from flowing out from the upper end of the threaded sleeve 5.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
