Description

Technical Field

[0001] This utility model relates to the technical field of manual wavelength analyzers, specifically a manual wavelength analyzer. Background Technology

[0002] Manual wavelength analyzers can perform qualitative and quantitative analysis of samples in the ultraviolet and visible spectral regions. They can be widely used in pharmaceuticals, clinical testing, biochemistry, petrochemicals, environmental monitoring, food hygiene, and quality control. They can also be used as teaching demonstration and experimental instruments for related courses in higher education institutions. However, existing manual wavelength analyzers still have certain shortcomings in use. During use, the device is mostly sealed, so repairing or replacing an internal component requires moving the entire monochromator, making assembly, adjustment, and maintenance inconvenient. Furthermore, the overall operation is inconvenient, and displacement during operation can easily lead to reduced accuracy of the results.

[0003] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number 202222009348.X, application date 2022-07-30) provides an ultraviolet-visible spectrophotometer, comprising a first cuvette groove, a second cuvette groove, a spring, a cuvette, a cuvette positioning block, a shaft-mounted open retaining ring, a pull rod, a cuvette groove bracket, a spring positioning block, a guide rail fixing sheet metal, a guide rail, a guide rail positioning spring, a spring sheet, and a steel ball. The first cuvette groove and the cuvette groove bracket are fixed together by screws, and the cuvette groove bracket and the cuvette positioning block are fixed together by screws. The steel ball is sandwiched between the guide rail positioning spring and the spring sheet and is fixed to the spring positioning block by screws. The pull rod is fastened to the cuvette positioning block. The cuvette is clamped by a ball-limiting spring, ensuring that light passes through the center of the cuvette, while the cuvette does not shift within the cuvette groove, thus ensuring high accuracy of the results.

[0004] While existing technology can ensure device stability, during operation, the cuvette is secured by a ball bearing retainer to ensure light passes through the center of the cuvette and to limit its position within the cuvette slot. This process requires coordination of multiple components, which may lead to operational difficulties. The overall light-seeking mechanism is complex, requires a long assembly and debugging time, and demands specialized skills. Furthermore, under high-frequency use, the contact surface between the steel ball and the guide rail will gradually wear down, reducing the securing effect and consequently affecting the accurate alignment of the light and the test results. This reduces the convenience of operation and the accuracy of testing.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing manual wavelength analyzer. Therefore, we proposed that a manual wavelength analyzer can effectively solve these problems. Summary of the Invention

[0006] The purpose of this invention is to provide a manual wavelength measurement device to solve the problems mentioned in the background art. Currently, the market uses ball bearing retaining springs to clamp the cuvette, ensuring that the light passes through the center of the cuvette and limiting the cuvette within the cuvette slot. The overall operation requires coordination of multiple components, which may lead to operational difficulties. The overall light-finding mechanism is complex, the assembly and debugging time is long, and professional skills are required. Furthermore, under high-frequency use, the contact surface between the steel ball and the guide rail will gradually be damaged, thereby reducing the clamping effect and affecting the accurate alignment of the light and the test results, thus reducing the convenience of operation and the accuracy of testing.
