Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube rack technology, specifically to a light-proof centrifuge tube rack. Background Technology

[0002] In flow cytometry assays, the incubation of antibodies and cells requires strict protection from light. However, most commercially available centrifuge tube racks lack caps, making effective light protection impossible. This allows light interference to the incubation process, potentially affecting the accuracy of the results.

[0003] Even more problematic is that many laboratory refrigerators have transparent glass doors. Even when centrifuge tube racks are placed in the refrigerator for low-temperature incubation, the transparent glass cannot block the penetration of external light, making it difficult to meet the experimental requirements for low-temperature, light-proof incubation and causing great inconvenience to experimental operations.

[0004] In addition, existing test tube racks have significant shortcomings in terms of test tube handling. Due to design deficiencies, operators often need to spend more time and effort handling test tubes, which not only affects the efficiency of the experiment but may also damage the test tubes or samples due to improper handling, causing unnecessary trouble for the experiment. Therefore, we propose a light-proof centrifuge tube rack. Utility Model Content

[0005] The purpose of this invention is to provide a light-proof centrifuge tube rack, which solves the problem of existing test tube racks being inconvenient for light-proof storage and retrieval through the cooperation of structures such as a light-proof cover, a retrieval component, and an adaptive component.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A light-shielding centrifuge tube rack includes a box body, and further includes: an upper tube rack installed inside the box body, the top of the upper tube rack being hinged with a light-shielding cover, an inner cover being installed on the light-shielding cover, and a lower tube rack installed at the bottom of the upper tube rack; an adaptive component installed on the upper tube rack, the adaptive component being used to adapt to test tubes of different sizes; and a retrieval component installed in the lower tube rack, the retrieval component being used to facilitate the retrieval of test tubes.

[0008] Preferably, the adaptive component includes grooves evenly spaced inside the upper tube rack, and all of the grooves are circular.

[0009] Preferably, adaptive springs are symmetrically installed inside each of the plurality of grooves, and the plurality of adaptive springs are distributed along the circumference of the grooves.

[0010] Preferably, each of the multiple adaptive springs has a retainer fixedly connected to one end away from the groove, and the multiple retainers can retract into the groove.

[0011] Preferably, the picking component includes a top rod movably installed inside the lower tube rack, and the top of the top rod is fixedly connected to a guide plate through the lower tube rack.

[0012] Preferably, a return spring is fixedly connected to the bottom of the guide plate, the other end of the return spring is fixedly connected to the bottom of the lower tube frame, and the bottom of the top rod extends through and out of the box body.

[0013] Preferably, the bottom of the box is symmetrically equipped with support legs, the box is equipped with a top cover, and a handle is fixedly connected to the top cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model has a top cover for sealing and storing test tubes, and also has a separate light-proof cover for protecting test tubes from light.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1:

[0027] Please see Figures 1-5 The light-shielding centrifuge tube rack shown in the diagram includes a box body 1, and further includes: an upper tube rack 13 installed inside the box body 1, with a light-shielding cover 9 hinged to the top of the upper tube rack 13, and an inner cover 10 installed on the light-shielding cover 9. The box body 1, the light-shielding cover 9, and the inner cover 10 are made of ABS material with excellent light-shielding performance. The inner cover 10 has a sealing gasket on the outside, and the sealing gasket is made of silicone material. Silicone has good elasticity and sealing properties, which can effectively block light from entering the interior of the box body 1, ensuring that the photosensitive reagents in the test tubes are not affected by light, and ensuring the stability of the experimental samples. A lower tube rack 12 is installed at the bottom of the upper tube rack 13. The main structure of the upper tube rack 13, the lower tube rack 12, etc., is made of high-strength polypropylene material, which not only has good chemical corrosion resistance and can resist the corrosion of common chemical reagents such as acids and alkalis in experiments, but also has excellent load-bearing capacity and can stably support multiple test tubes. Also included are: an adaptive component 5 installed on the upper tube rack 13, which is used to adapt to test tubes of different sizes; and a retrieval component 6 installed in the lower tube rack 12, which is used to facilitate the retrieval of test tubes.

[0028] Furthermore, the adaptive component 5 includes grooves 11 evenly distributed inside the upper tube rack 13. All grooves 11 are circular, and there are recessed holes above the grooves 11 to increase the available area, thereby making it easier for the user to put the test tubes into the upper tube rack 13.

[0029] Furthermore, adaptive springs 7 are symmetrically installed inside multiple grooves 11. These springs are made of high-elasticity manganese steel, which has excellent elasticity and fatigue resistance and can maintain good elasticity even after long-term use. Multiple adaptive springs 7 are distributed around the grooves 11, making the clamping force on the test tube more uniform.

[0030] Specifically, each of the multiple adaptive springs 7 has a retaining sleeve 8 fixedly connected to its end furthest from the groove 11. The retaining sleeves 8 can retract into the groove 11. Made of food-grade silicone, the retaining sleeves 8 are soft and will not scratch or damage the test tube wall. Their retractable design, combined with the adaptive springs 7, allows for flexible adaptation to test tubes of different diameters. When a test tube is placed in, the retaining sleeves 8 automatically adjust their position under the action of the adaptive springs 7, tightly wrapping the test tube and achieving stable fixation. The adaptive component 5 can accommodate test tubes of different sizes, eliminating the need for multiple tube racks for different specifications, greatly improving the equipment's versatility and reducing experimental costs.

[0031] Example 2:

[0032] This embodiment provides a further explanation of Example 1, based on... Figure 1 , Figure 4 and Figure 5 As shown, it is worth noting that the lifting component 6 includes a push rod 14 movably installed inside the lower tube rack 12, made of stainless steel. The top of the push rod 14 passes through the lower tube rack 12 and is fixedly connected to a guide plate 16, also made of stainless steel, with an internal soft pad to reduce friction with the bottom of the test tube and prevent damage. The reset spring 15 is made of high-quality carbon spring steel, with good elasticity and excellent recovery performance, ensuring that the guide plate 16 can quickly reset after lifting the test tube.

[0033] Specifically, a reset spring 15 is fixedly connected to the bottom of the guide plate 16, and the other end of the reset spring 15 is fixedly connected to the bottom of the lower tube frame 12. The bottom of the top rod 14 passes through and extends to the outside of the box 1.

[0034] Further reference Figure 1 As shown, support legs 2 are symmetrically installed at the bottom of the box 1. Support legs 2 enhance the stability of the tube rack. A top cover 3 is installed on the box 1. A handle 4 is fixedly connected to the top cover 3. The handle 4 on the top cover 3 makes it easy to carry and move, making the experimental operation more flexible and convenient.

[0035] The principle behind this solution is as follows:

[0036] First, when test tubes need to be placed, the user opens the top cover 3 and inserts the test tube through the through hole in the upper tube rack 13. After the test tube enters the groove 11, it will squeeze the retaining sleeve 8. The retaining sleeve 8 will cause the adaptive spring 7 to contract. The reaction force generated by the adaptive spring 7 will make the retaining sleeve 8 tightly hold the test tube, thereby achieving a stable fixation for test tubes of different sizes. At this time, the bottom of the test tube rests on the guide plate 16, and the return spring 15 is in a compressed state.

[0037] Secondly, when it is necessary to take out the test tube, the user presses the bottom of the top rod 14, the top rod 14 drives the guide plate 16 to move upward, the guide plate 16 lifts the test tube, so that the top of the test tube is exposed on the upper tube rack 13, making it convenient for the user to take out.

[0038] Finally, after releasing the push rod 14, the spring force of the return spring 15 returns the guide plate 16 and the push rod 14 to their original positions, ready for the next use. The cooperation between the light-proof cover 9 and the inner cover 10 can effectively block external light from entering the interior of the box 1, providing a good light-proof environment for the photosensitive reagent in the test tube.

[0039] It is understood that this utility model is described through some embodiments, and as those skilled in the art will know, various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
