[0022] AsFigure 1 As shown in the figure, the present utility model provides a colorimetric tube fixing component for fixing a colorimetric tube in a jack of a sample tray, including:

[0023] A plugging part 1 and a clamping part. One end of the plugging part 1 is integrally connected to the clamping part. The plugging part 1 is used to be inserted into the jack. The inner circumference of the plugging part 1 can accommodate the colorimetric tube to pass through. The clamping part includes a plurality of clamping claws 2. One end of the plurality of clamping claws 2 away from the plugging part 1 inclines towards the direction of approaching each other, and a clamping space is formed inside the plurality of clamping claws 2. The clamping space is used to clamp the colorimetric tube.

[0024] Specifically, to solve the problem that when a colorimetric tube is inserted into a jack on a sample tray in the prior art, it is difficult to truly fix the colorimetric tube. As the sample tray drives the colorimetric tube to rotate, the colorimetric tube will vibrate, which will have an adverse impact on the absorbance detection of the test liquid. The colorimetric tube fixing component provided by the present utility model has a plugging part 1 and a clamping part. Through the plugging part 1, the plugging with the jack of the sample tray can be realized, and the fixing of the colorimetric tube fixing component on the sample tray can be realized. Through the plurality of clamping claws 2 of the clamping part, the colorimetric tube inserted into it can be clamped. Thus, even when there are tolerances in the outer diameter size of the colorimetric tube, it can be ensured that the colorimetric tube is fixed on the sample tray and will not vibrate with the rotation of the sample tray, avoiding affecting the repeatability of the detection result when detecting the absorbance of the test liquid in the colorimetric tube and improving the reproducibility of the absorbance detection.

[0025] Optionally, the colorimetric tube fixing component is an elastomer. When the colorimetric tube is inserted into the clamping space, the plurality of clamping claws 2 can undergo elastic deformation.

[0026] Specifically, the colorimetric tube fixing component is integrally made of a material with a certain elasticity to form an elastomer. When the colorimetric tube is inserted into the clamping space surrounded by the plurality of clamping claws 2, the clamping claws 2 clamp the colorimetric tube through elastic deformation, thereby fixing the colorimetric tube on the sample tray.

[0027] Optionally, the material of the colorimetric tube fixing component is plastic or rubber.

[0028] Specifically, the colorimetric tube fixing component can be made of plastic or rubber material, which can ensure its structural strength while meeting the requirements of elastic deformation.

[0029] Optionally, the plugging part 1 is cylindrical, and the outer circumference of the plugging part 1 can be bonded to the jack.

[0030] Specifically, the outer circumference of the plugging part 1 can be connected to the inner circumference of the jack by gluing. The cylindrical plugging part 1 can ensure a sufficient bonding area.

[0031] Optionally, the inner diameter of the plugging part 1 is 0.05 - 0.15 mm larger than the outer diameter of the colorimetric tube.

[0032] Specifically, the insertion part 1 is not used for positioning the colorimetric tube, so its inner diameter is larger than the outer diameter of the colorimetric tube to ensure that the colorimetric tube can pass through the insertion part 1 smoothly.

[0033] Optionally, the clamping part includes a conical body part. A plurality of through slots 3 are formed in the outer wall of the end of the body part far from the insertion part 1 to form a plurality of clamping claws 2.

[0034] Specifically, the plurality of clamping claws 2 are formed by opening a plurality of through slots 3 in the body part.

[0035] In this embodiment, there are 6 through slots 3, and the 6 through slots 3 are evenly distributed in the circumferential direction on the body part. The 6 clamping claws 2 are in the shape of 6 petals, which can be regarded as dividing the body part into 6 units along the circumferential direction. 1 / 3 of each unit is the through slot 3, and 2 / 3 retains the side wall to form the clamping claw 2.

[0036] Optionally, the outer diameter of the end of the body part close to the insertion part 1 is larger than the outer diameter of the insertion part 1.

[0037] Specifically, the outer diameter of the end of the body part close to the insertion part 1 is larger than the outer diameter of the insertion part 1 to form a limiting step, which can form a limit when the insertion part 1 is inserted into the jack and keep the axis of the colorimetric tube fixing part collinear with the axis of the jack.

[0038] Optionally, the inner diameter of the end of the body part far from the insertion part 1 is 0.5 - 1.5 mm smaller than the outer diameter of the colorimetric tube.

[0041] Specifically, the wall thickness of the body part is smaller than that of the insertion part 1, which is beneficial to its elastic deformation to realize the clamping of the colorimetric tube.

[0042] In this embodiment, the wall thickness of the insertion part 1 is 1.5 mm, and the wall thickness of the body part is 1 mm.

[0043] Optionally, a chamfer is provided on the inner circumference of the end of the body part far from the insertion part 1.

[0044] Specifically, the setting of the chamfer forms a guiding function, making it easier for the semi-circular colorimetric tube at the bottom to be inserted into the clamping space surrounded by the plurality of clamping claws 2.

[0045] In this embodiment, the height of the insertion part 1 is 10 mm, and the height of the clamping part is 20 mm.

[0046] In summary, taking the first use of the colorimetric tube fixing component provided by the present utility model as an example: Apply glue to the insertion part 1 of the colorimetric tube fixing component and insert it into the jack of the sample tray to bond with the sample tray. Multiple jacks are provided on the sample tray, and multiple colorimetric tubes can be inserted. As the sample tray rotates, multiple colorimetric tubes can pass through the detection optical path in sequence, and then the absorbance of the test solution in the colorimetric tube can be detected by the detector; after the colorimetric tube fixing component is fixed on the sample tray, insert the colorimetric tube into the colorimetric tube fixing component. When the digestion colorimetric tube is inserted, the six petal-shaped clamping jaws 2 play a role in clamping and fastening the colorimetric tube, and the colorimetric tube containing the digested test solution will not undergo obvious displacement due to loosening or vibration when the sample tray rotates, improving the reproducibility of the absorbance detection of the test solution.
