[0001] The utility model relates to the technical field of dose measurement, in particular to a card for preventing colorimetric cuvette pollution in dose measurement. Background Art

[0002] When a colorimetric cuvette containing a liquid to be quantitatively detected is placed on a colorimetric cuvette inner support bracket for an irradiation dose distribution experiment, it is required that the experimenter does not touch the smooth surface of the colorimetric cuvette when taking and placing the colorimetric cuvette. However, due to the complex operation process of the experiment, problems such as misoperation (accidentally touching the smooth surface of the colorimetric cuvette) are likely to occur. Moreover, in the drainage and reflux processes during the experiment, the liquid pipeline layout is relatively irregular, which is likely to cause the problem of experimental failure. Therefore, the utility model provides a card for preventing colorimetric cuvette pollution in dose measurement to assist in dose measurement experiments. Summary of the Utility Model

[0038] Refer to Figures 1-7, A clamping component for preventing colorimetric cuvette contamination in dose measurement provided by the utility model includes: a clamping component body 1 and a clamping component 8. Among them, a rectangular through hole 3 penetrating the upper end and the lower end of the clamping component body 1 is provided at the center of the clamping component body 1 for a drainage pipe to pass through the rectangular through hole 3 and insert downward. A reflux pipe leading-out part 2 is fixedly connected to the side of the clamping component body 1 and near its top. A pipe hole 4 communicating with the rectangular through hole 3 is provided at the end of the reflux pipe leading-out part 2 for a reflux pipe to be connected to the pipe hole 4, so that the reflux liquid can pass through the reflux pipe leading-out part 2, enter the rectangular through hole 3, and then flow downward from the rectangular through hole 3. An installation cavity 6 communicating with the rectangular through hole 3 is provided at the bottom end of the clamping component body 1, and the clamping component 8 is arranged inside the installation cavity 6 for fixedly connecting the colorimetric cuvette inserted into the inner side of the rectangular through hole 3 with the clamping component body 1.

[0039] For example, the overall diameter of the rectangular through hole 3 can be set to 1 cm * 1 cm and used in cooperation with a colorimetric cuvette with an outer diameter of 1 cm * 1 cm. The top end of the colorimetric cuvette can be inserted into the bottom end of the rectangular through hole 3, or only the bottom diameter of the rectangular through hole 3 can be set to 1 cm * 1 cm, and the upper diameter of the rectangular through hole 3 is smaller than the bottom diameter of the rectangular through hole 3.

[0040] When using this device, insert the top end of the colorimetric cuvette into the bottom end of the rectangular through hole 3, and then adjust the clamping component 8 to fixedly connect the colorimetric cuvette with the clamping component body 1. When the user performs subsequent operations, the colorimetric cuvette is taken and placed by grasping the outside of the clamping component body 1, thus avoiding accidentally touching the smooth surface of the colorimetric cuvette and affecting the accuracy of the experiment.

[0041] The rectangular through hole 3 is used for a drainage pipe to pass through the rectangular through hole 3 and insert downward into the colorimetric cuvette. The reflux pipe leading-out part 2 is used for connecting the reflux pipe, which can keep the reasonable layout of each pipe and the layout is relatively standard, thus reducing the risk of experimental operation.

[0042] A plurality of inner convex parts 9 are fixedly connected to the inner side of the rectangular through hole 3 and near the top end. The inner convex parts 9 protrude inward, making the top port of the rectangular through hole 3 smaller, thereby reducing the entry of stray light into the colorimetric cuvette; moreover, the bottom end of the clamping component body 1 can be set to be the same as the bottom end of the light-shielding cover, which can be installed on the top of the colorimetric cuvette support in cooperation, thus eliminating the operation of using the light-shielding cover.

[0043] In one embodiment, a side hole 5 perpendicular to and communicating with the pipe hole 4 is provided on the side of the reflux pipe leading-out part 2. After the reflux pipe is inserted into the pipe hole 4, a long screw for fixing the reflux pipe can be threadedly connected to the side hole 5.

[0044] In one embodiment, it further includes: a positioning part 7. The positioning part 7 is fixedly connected to the clamping component body 1, and the positioning part 7 has a limiting part 702 located inside the rectangular through hole 3.

[0045] The positioning member 7 is used to limit the depth of insertion of the cuvette into the rectangular through hole 3. Specifically, when the cuvette is inserted upward, the top end of the cuvette abuts against the limiting portion 702, and then the clamping assembly 8 can be adjusted to fixedly connect the cuvette to the card body 1.

[0046] Specifically, the positioning member 7 includes a rotating column 701. A first mounting hole perpendicular to and communicating with the rectangular through hole 3 is formed in the side surface of the card body 1. The rotating column 701 is fixedly installed inside the first mounting hole, and the limiting portion 702 is fixedly installed at one end of the rotating column 701 located inside the rectangular through hole 3.

[0047] In one embodiment, there are four inner convex portions 9. The side of the inner convex portion 9 facing the center of the rectangular through hole 3 is arc-shaped, leaving a hole at the center of the rectangular through hole 3 to prevent the inner convex portion 9 from affecting the insertion of the drainage pipe into the rectangular through hole 3.

[0048] In one embodiment, the clamping assembly 8 includes a fixed shaft 801, an inverted U-shaped member 802, a connecting frame 803, a wedge block 807, and a rotating portion 805.

[0049] Among them, the fixed shaft 801 is fixedly installed inside the installation cavity 6. The inverted U-shaped member 802 is stuck on the fixed shaft 801, and both vertical segments of the inverted U-shaped member 802 are arc-shaped. Both vertical segments of the U-shaped member 802 have the ability of elastic deformation. An inner support frame is fixedly connected between the two vertical segments of the inverted U-shaped member 802 and near the top of the inverted U-shaped member 802. The two vertical segments of the inverted U-shaped member 802 at the part with the inner support frame are basically deformed synchronously. The connecting frame 803 is fixedly connected to the inner side of the installation cavity 6. The vertical segment of the inverted U-shaped member 802 far from the rectangular through hole 3 is fixedly connected to the connecting frame 803. The wedge block 807 is located obliquely above the inverted U-shaped member 802, and one side surface of the wedge block 807 is vertically slidably connected to the inner side of the installation cavity 6. A second mounting hole perpendicular to and communicating with the installation cavity 6 is formed in the side surface of the card body 1. The rotating portion 805 is rotatably connected to the second mounting hole. An eccentric portion 806 is fixedly connected to one end of the rotating portion 805 located inside the installation cavity 6, and the eccentric portion 806 is located above the wedge block 807.

[0050] The user rotates the rotating portion 805 to make the eccentric portion 806 rotate, thereby pushing the wedge block 807 downward. The wedge block 807 pushes the vertical segments of the inverted U-shaped member 802 at the part with the inner support frame downward, causing both vertical segments of the inverted U-shaped member 802 to deform. Among them, the vertical segment of the inverted U-shaped member 802 close to the rectangular through hole 3 deforms toward the rectangular through hole 3, squeezing the cuvette, and further fixedly connecting the cuvette to the card body 1.

[0051] In one embodiment, two sets of clamping assemblies 8 are symmetrically arranged to clamp and fix the cuvette from both sides.

[0052] In one embodiment, an anti-slip pad 804 is fixedly connected to the vertical section of the inverted U-shaped member 802 close to the rectangular through hole 3, so as to prevent the colorimetric cuvette after clamping from sliding on the vertical section of the inverted U-shaped member 802 close to the rectangular through hole 3, and causing the colorimetric cuvette to fall off.

[0053] Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
