Description

Technical Field

[0001] This utility model relates to the field of biopharmaceutical technology, and in particular to a cuvette holder for protein concentration detection. Background Technology

[0002] In the field of biopharmaceutical technology, protein concentration detection is an indispensable and important part of experimental research and production. The accurate determination of protein concentration is of great significance for drug development, quality control, and biological sample analysis. At present, protein concentration detection usually adopts spectral analysis methods, which determine the protein concentration by measuring the absorbance value of light of a specific wavelength passing through the protein solution in the cuvette.

[0003] Traditional cuvette holders often lack effective light-shielding designs during use, allowing ambient light to easily enter the cuvette and cause light scattering. This affects the accuracy and reliability of measurement results. Light scattering refers to the phenomenon where light deviates from its original propagation direction when passing through a cuvette due to factors such as unevenness on the cuvette surface, impurities in the solution, or air bubbles. This scattered light interferes with the measuring instrument's detection of specific wavelengths of light, leading to deviations in absorbance values ​​and consequently affecting the accurate determination of protein concentration. In practical applications, this deviation may result in inaccurate experimental results, affecting subsequent experimental analysis and research conclusions. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cuvette holder for protein concentration detection.

[0005] This utility model is achieved using the following technical solution: a cuvette holder for protein concentration detection, comprising a base, a cuvette holder body fixedly connected to the upper surface of the base, an mounting sleeve fixedly connected to the upper surface of the base, a pressure-bearing block slidably connected inside the mounting sleeve, a spring fixedly connected to the lower surface of the pressure-bearing block, a retrieval frame fixedly connected to the outer surface of the mounting sleeve, a spring fixedly connected to the inner wall of the retrieval frame, a movable plate fixedly connected to the surface of the spring, a locking rod fixedly connected to one side of the movable plate, a pull rod fixedly connected to the other side of the movable plate, an insert block snapped into the inside of the mounting sleeve, and a light shield fixedly connected to the surface of the insert block.

[0006] Through the above technical solutions, the light shield can not only effectively block ambient light, ensuring that only light of a specific wavelength passes through the cuvette during the measurement process, reducing the impact of light scattering on the measurement results, thereby improving the accuracy and reliability of the measurement, but also facilitate quick installation and disassembly by personnel, reducing the workload of disassembly and assembly, and improving work efficiency.

[0007] As a further improvement to the above solution, two mounting sleeves are provided, and the two mounting sleeves are respectively fixedly connected to both sides of the upper surface of the base.

[0008] As a further improvement to the above solution, the light shield is a black anodized aluminum light shield, which is fitted onto the outer surface of the cuvette holder body.

[0009] Through the above technical solution, the black anodized aluminum material has good light-shielding performance and corrosion resistance, which can effectively block external light from entering the cuvette, further reduce the impact of light scattering on the measurement results, and at the same time improve the service life of the light shield, ensuring that the cuvette holder can work stably under different environmental conditions.

[0010] As a further improvement to the above solution, the surface of the embedded block is provided with a limiting groove, and the embedded block is adapted to the locking rod.

[0011] The above technical solution restricts the mutual adaptation design of the slot and the locking rod, so that the locking rod can be accurately inserted into the embedded block, thereby locking the embedded block more firmly and ensuring that the sunshade will not easily loosen or fall off after installation.

[0012] As a further improvement to the above solution, the surface of the mounting sleeve is provided with a slot that is compatible with the locking rod, and the locking rod passes through the slot and the interior of the limiting slot.

[0013] As a further improvement to the above solution, the surface of the base is provided with a preset mounting groove, and the number of preset mounting grooves is four, which are respectively located at the four corners of the outer surface of the base.

[0014] Through the above technical solution, the design of the pre-installed mounting slot allows the cuvette holder to be installed more stably on the workbench or other suitable positions, avoiding the impact of the measurement results on the accuracy of the measurement results due to the shaking of the holder during the measurement process. At the same time, it is also convenient to flexibly adjust the installation position of the holder according to actual use needs, thereby improving the applicability and stability of the cuvette holder.

[0015] As a further improvement to the above solution, the embedded block and the pressure-bearing block are adapted to each other, and the inner wall of the mounting sleeve is provided with a sliding groove, and the pressure-bearing block is slidably connected to the inside of the sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows for quick disassembly of the light shield by pulling a lever, which retracts the movable plate and locking lever. The locking lever disengages from the embedded block, and the spring below the pressure block resets, lifting the pressure block and ejecting the embedded block. This enables the light shield to be quickly and securely installed on the cuvette holder, effectively blocking ambient light and ensuring that only light of a specific wavelength passes through the cuvette during measurement. This reduces the impact of light scattering on the measurement results, thereby improving the accuracy and reliability of the measurement. Furthermore, the quick-installation design not only facilitates operation but also reduces the workload, improving work efficiency and avoiding measurement delays or operational inconveniences caused by difficulties in installing or removing the light shield.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example: Please combine Figure 1-4This embodiment of a cuvette holder for protein concentration detection includes a base 1, a cuvette holder body 2 fixedly connected to the upper surface of the base 1, a mounting sleeve 3 fixedly connected to the upper surface of the base 1, a pressure block 4 slidably connected inside the mounting sleeve 3, a spring 5 fixedly connected to the lower surface of the pressure block 4, a retrieval frame 6 fixedly connected to the outer surface of the mounting sleeve 3, a spring 7 fixedly connected to the inner wall of the retrieval frame 6, a movable plate 8 fixedly connected to the surface of the spring 7, a locking rod 9 fixedly connected to one side of the surface of the movable plate 8, and a pull rod 10 fixedly connected to the other side of the surface of the movable plate 8. An insert block 11 is snapped into the inside of the mounting sleeve 3, and a light shield 12 is fixedly connected to the surface of the insert block 11. In use, the protein solution to be tested is first added to the cuvette, and then the cuvette containing the sample is placed into the cuvette holder body 2. When the light shield 12 is not installed, the pressure block 4 is at the top of the mounting sleeve 3, preventing the locking rod 9 from popping out, the movable plate 8 compresses the locking rod 9, and the pull rod 10... The surface of the recycling frame 6 has a certain amount of movement. When the light shield 12 is installed, the embedded block 11 on the surface of the light shield 12 is inserted into the pressure block 4 inside the mounting sleeve 3. Spring 7 presses down on the pressure block 4, compressing spring 5. As the pressure block 4 descends, the embedded block 11 gradually enters the mounting sleeve 3. When the pressure block 4 descends to a certain depth and no longer blocks the locking rod 9, spring 7 in the recycling frame 6 resets, pushing the movable plate 8 and the locking rod 9 to extend, and the pull rod 10 moves to the return position. On the surface of frame 6, locking rod 9 is inserted into the embedded block 11 to lock the embedded block 11 in the current position, completing the installation of light shield 12, which wraps around the cuvette holder body 2 to shield ambient light. After measurement, when removing light shield 12, pull rod 10 to retract movable plate 8 and locking rod 9. Locking rod 9 disengages from the embedded block 11, and spring 5 under pressure block 4 resets to lift pressure block 4, pushing out embedded block 11, thereby quickly removing light shield 12.

[0021] There are two mounting sleeves 3, which are fixedly connected to both sides of the upper surface of the base 1.

[0022] The light shield 12 is a black anodized aluminum light shield, which is fitted onto the outer surface of the cuvette holder body 2.

[0023] The surface of the embedded block 11 is provided with a limiting hole groove 13, and the embedded block 11 and the locking rod 9 are mutually compatible.

[0024] The surface of the mounting sleeve 3 has a slot that matches the locking rod 9, and the locking rod 9 passes through the slot and the interior of the limiting slot 13.

[0025] The base 1 has four preset mounting slots 14 on its surface. The four preset mounting slots 14 are located at the four corners of the outer surface of the base 1, which makes it convenient for personnel to fix the base 1 in a suitable working position with bolts.

[0026] The embedded block 11 and the pressure-bearing block 4 are adapted to each other. The inner wall of the mounting sleeve 3 is provided with a sliding groove, and the pressure-bearing block 4 is slidably connected to the inside of the sliding groove.

[0027] The implementation principle of a cuvette holder for protein concentration detection in this embodiment is as follows: First, the operator fixes the base 1 in a suitable working position with bolts. The design of the pre-set mounting groove 14 allows the cuvette holder to be installed more stably on the workbench or other suitable position. The operator adds the protein solution to be tested into the cuvette, and then places the cuvette containing the sample into the cuvette holder body 2. When the light shield 12 is not installed, the pressure block 4 is located at the top of the mounting sleeve 3, the blocking locking rod 9 pops out, the movable plate 8 compresses the locking rod 9, and the pull rod 10 and the surface of the recovery frame 6 have a certain amount of movement.

[0028] When the light shield 12 needs to be installed, insert the embedded block 11 on the surface of the light shield 12 into the pressure block 4 inside the mounting sleeve 3. At this time, the second spring 7 presses down the pressure block 4, compressing the first spring 5. As the pressure block 4 descends, the embedded block 11 gradually enters the mounting sleeve 3. When the pressure block 4 descends to a certain depth and no longer blocks the locking rod 9, the second spring 7 in the recovery frame 6 resets, pushing the movable plate 8 and the locking rod 9 to extend. The pull rod 10 moves to the surface of the recovery frame 6, and the locking rod 9 inserts into the embedded block 11, locking the embedded block 11 in the current position, thus completing the installation of the light shield 12. This allows the light shield 12 to be quickly and firmly installed on the cuvette holder body 2, effectively shielding ambient light and ensuring that only light of a specific wavelength passes through the cuvette during the measurement process, reducing the influence of light scattering on the measurement results.

[0029] Then, after the measurement is completed, when it is necessary to remove the sunshade 12, simply pull the lever 10 to retract the movable plate 8 and the locking lever 9. The locking lever 9 will disengage from the inside of the embedded block 11. At this time, the spring 5 under the pressure block 4 will reset, lifting the pressure block 4 and pushing out the embedded block 11, thereby quickly removing the sunshade 12.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
