Description

Technical Field

[0001] The utility model belongs to the field of optical analysis instruments, and in particular relates to an adjustable fluorescence receiving frame applied to a multifunctional optical analyzer. Background Art

[0002] Fluorescence detection is widely used in life sciences, chemistry, materials science and other fields due to its high sensitivity, fast detection speed and accurate analysis results. By using a multifunctional optical analyzer with fluorescence intensity detection mode, a special wavelength is used to excite the fluorescent group of the target substance, and the fluorescence detection unit receives it, so as to obtain relevant information of the target substance.

[0003] At present, the fluorescence receiving frame of the existing multifunctional optical analyzer can only detect liquid samples. The shape of the fluorescence receiving frame cannot fix solid samples. If you want to detect solid samples, you need to replace the special fluorescence sample frame, which is very inconvenient.

[0004] Therefore, in order to address the problem that the fluorescence receiving frame of the above-mentioned existing multifunctional optical analyzer can only perform fluorescence detection on liquid samples but cannot detect solid samples, the existing fluorescence receiving frame is improved and a clamping component is designed to fix solid samples so that the fluorescence receiving frame has the function of detecting solid samples.

[0007] Preferably, a clamping assembly for fixing solid samples is added to the fluorescent sample rack, and the solid samples are fixed by the clamping assembly, thereby increasing the versatility of the fluorescence receiving rack of the multifunctional optical analyzer. The clamping assembly is moved out of the detection box by the No. 1 sliding assembly to facilitate the fixation of the solid samples. The No. 2 sliding assembly is used to move the fluorescence detector.

[0008] Preferably, a mounting column is fixedly connected to the fluorescent sample rack, and a storage groove matching the test tube is provided on the fluorescent sample rack. The storage groove matches the shape of the test tube, and the test tube containing the liquid sample can be inserted into the storage groove to limit the position of the sample and ensure that the fluorescent detector is aligned with the sample, thereby facilitating fluorescence detection.

[0009] Preferably, the clamping assembly includes a column, a support frame, and a fixed block; two columns opposite to each other on the left and right are fixedly connected to the fluorescence receiving frame, a support frame with a movable groove on the surface is fixedly connected to the column, a T-shaped fixed block is slidably connected in the movable groove, a glass slide for clamping the solid sample is installed between the fixed block and the support frame, and the glass slide is fixed by the fixed block and the support frame from four directions of up, down, left and right to tightly fix the glass slide for fixing the solid sample.

[0010] Preferably, the clamping assembly also includes a positioning column and a spring; the positioning column is fixedly connected in the movable groove, the fixed block is sleeved on the positioning column, and the spring is sleeved on the outside of the positioning column, one end of the spring is connected to the inner wall of the movable groove, and the other end of the spring is connected to the fixed block. The positioning column can play a guiding role to prevent the spring from deflecting during extension and contraction, and the spring can be used to fix glass slides of different lengths.

[0012] Preferably, a moving block is provided on the box cover, and the fluorescence detector is arranged at the bottom end of the moving block. A piston rod is installed on the moving block and connected to a cylinder on the fluorescence detector. After the cylinder is started, the piston rod pushes the fluorescence detector downward to make it close to the surface of the test tube or glass slide, thereby ensuring the accuracy of fluorescence detection.

[0028] See also Figure 3 , 6In this embodiment, the No. 1 sliding assembly includes a No. 1 slide groove 801 and a drawer 802; the No. 1 slide groove 801 is provided on the detection box 1, and the drawer 802 is slidably connected in the No. 1 slide groove 801, and the fluorescent sample rack 2 is installed in the drawer 802. A moving block 9 is provided on the box cover 3, and the fluorescent detector 4 is provided at the bottom of the moving block 9. The moving block 9 is equipped with a cylinder 10 connected to the fluorescent detector 4 by a piston rod, and the No. 2 sliding assembly includes a No. 2 slide groove 1101 and a slider 1102; the box cover 3 is provided with two No. 2 slide grooves 1101 opposite to each other on the left and right, and the slider 1102 is slidably connected in the No. 2 slide groove 1101, The moving block 9 is fixedly connected between the two sliders 1102. The drawer 802 is moved in the slide groove to change the position of the fluorescent sample rack 2 and the clamping assembly in the detection box 1. The setting of the drawer 802 allows the installation of the sample to be carried out on the outside of the detection box 1 to prevent the narrow space in the detection box 1 from affecting the installation and fixation of the sample.

After releasing the hand, the fixed block 703 loses the external force squeezing, and the spring 705 pops out the fixed block 703, so that the fixed block 703 is close to the glass slide, and cooperates with the support frame 702 to fix the solid sample;

[0031] The fluorescence detector 4 emits light that is adjusted to a certain specific wavelength through a filter. The light irradiates the surface of the sample and excites the fluorescent groups of the sample.
