Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a test tube rack with an adjustable multi-hole insert plate. Background Technology

[0002] In routine laboratory experiments, test tube racks are core consumables, primarily responsible for storing and securing test tubes, as well as for adding materials and mixing reactions during experiments. They are widely used in fields such as chemistry, biology, and medicine. Currently, most commercially available test tube racks are one-piece molded porous support structures, commonly featuring designs with fixed aperture diameters and fixed support heights, which can only accommodate test tubes of a specific size (such as a fixed diameter or length). While some improved adjustable racks attempt to optimize adaptability, for example by incorporating detachable vertical and horizontal bars within the frame, allowing adjustment of the grid size by sliding the vertical bars along the horizontal guide grooves and the horizontal bars along the vertical guide grooves, thus accommodating test tubes of different diameters, these structures still primarily focus on meeting basic storage and simple adjustment needs, without deeply optimizing for ease of experimental operation.

[0003] Existing test tube racks of this type have significant limitations in practical applications: Firstly, it is difficult to balance adaptability and practicality. Fixed aperture models are incompatible with test tubes of various diameters and lengths in the laboratory, requiring researchers to equip themselves with multiple test tube racks of different specifications, increasing usage costs and space occupation. Adjustable test tube racks that rely on vertical and horizontal bars for adjustment have cumbersome adjustment steps and lack a stable fixing structure, making test tubes prone to loosening during shaking. Secondly, if the experiment requires sealing the test tubes, each test tube must be individually capped and capped one by one. During cleaning, the caps and test tubes must be removed one by one, making the operation process cumbersome. Utility Model Content

[0004] The present invention aims to provide a test tube rack with an adjustable multi-hole insert plate to solve the problems of existing test tube racks being unable to accommodate test tubes of various sizes, lacking convenient capping function, and having low cleaning efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a test tube rack with an adjustable multi-hole insert plate, comprising a main frame, a multi-hole insert plate, and a silicone cap. The side wall of the main frame is provided with an adjustment groove, and the upper and lower inner surfaces of the adjustment groove are provided with concave guide rails along the diagonal direction. The main frame is provided with a fixing bolt corresponding to the position of the adjustment groove. The upper and lower surfaces of the multi-hole insert plate are provided with protruding guide rails along the diagonal direction. The protruding guide rails match the concave guide rails, and the multi-hole insert plate can slide along the concave guide rails. The silicone cap is located on the top of the main frame.

[0006] The principle of this solution is as follows: When it is necessary to accommodate test tubes of different diameters, the multi-hole insert can be slid along the diagonal guide rail. By changing the relative position of the multi-hole insert and the test tube hole of the main frame, the actual hole diameter of the test tube is adjusted until the hole diameter matches the target test tube diameter. After adjustment, tighten the fixing bolt at the corresponding adjustment slot position of the main frame. The fixing bolt can limit and fix the multi-hole insert, preventing it from shifting during subsequent use and ensuring stable clamping after the test tube is placed. The silicone cap located at the top of the main frame can cover the main frame after the test tube is placed, forming a shield or seal on the test tube opening to prevent external impurities from falling into the test tube, while protecting the material inside the test tube and ensuring the stability of the material and the cleanliness of the experimental environment during the experiment.

[0007] The advantages of this design are: 1. The multi-hole insert plate, through the sliding engagement of the protruding guide rail and the concave guide rail of the main frame, can flexibly adjust the diameter of the test tube holes, achieving adaptation to test tubes of different diameters and solving the problem of poor adaptability of single-diameter test tube racks; 2. The fixing bolts of the main frame can fix the position of the multi-hole insert plate after it is adjusted to the correct position, preventing the insert plate from shifting during use, ensuring stable clamping of the test tubes, and preventing the test tubes from tipping over or shaking and affecting the experiment; 3. The silicone cap on the top of the main frame can cover the test tube opening, which can not only prevent external impurities from contaminating the material inside the test tube, but also prevent material leakage or environmental influence, ensuring the stability of the experimental materials.

[0008] Preferably, as an improvement, the side wall of the main frame is provided with multiple slots, which are located at the bottom of the adjustment groove, and a pluggable movable base plate is connected to each slot. The multiple slots on the side wall of the main frame provide different height installation positions for the pluggable movable base plate. By selecting different slots to insert the base plate, test tubes of different lengths can be accommodated, avoiding instability of the test tubes due to insufficient length and expanding the adaptability range of the test tube rack.

[0009] Preferably, as an improvement, the pluggable movable base plate is adapted to the size of the slot. This adaptation ensures a secure and stable installation after insertion, providing reliable support for the bottom of the test tube and further guaranteeing the stability of the test tube after placement.

[0010] Preferably, as an improvement, the bottom of the silicone cap is provided with multiple right-angled wedge-shaped protrusions, which correspond to the positions of the test tube holes on the main frame. The correspondence between the right-angled wedge-shaped protrusions at the bottom of the silicone cap and the test tube holes allows for precise fitting of test tube openings of different diameters, enhancing the sealing effect, preventing leakage or evaporation of liquid inside the test tube, and improving the versatility of the seal.

[0011] Preferably, as an improvement, the top of the main frame is provided with multiple fixing slots, and the bottom of the silicone cover is provided with multiple fixing feet that can be adapted to the fixing slots. The matching and cooperation between the fixing slots of the main frame and the fixing feet of the silicone cover can firmly fix the silicone cover to the main frame, preventing the silicone cover from falling off when shaken or moved, ensuring a stable sealing state, and improving operational safety.

[0012] Preferably, as an improvement, the silicone cap is the same size as the main frame, and the right-angled wedge-shaped protrusion of the silicone cap can be adapted to test tube openings of different diameters to achieve a seal. The silicone cap's consistent size with the main frame allows for full coverage, and the right-angled wedge-shaped protrusion, combined with its adaptability to test tube openings of different diameters, ensures a complete seal while eliminating the need for separately equipped caps of different specifications, thus improving operational convenience and sealing versatility.

[0015] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figure 1 -Appendix Figure 4As shown: A test tube rack with an adjustable multi-hole insert plate includes a main frame 2, a multi-hole insert plate 5, a silicone cap 1, and a pluggable movable base plate 6. The main frame 2 is made of one-piece molded plastic and has 48 test tube holes, arranged in a row of 12 holes and a column of 4 holes. The opening of each test tube hole is a square with a side length of 2.1 cm and a depth of 10 cm. The upper surface of the main frame 2 has a fixing groove 201 at each of the four corners and the middle. The side wall of the main frame 2 has an adjustment groove and three slots 4 arranged sequentially from bottom to top. The cross-sectional area of ​​the adjustment groove and the three slots 4 corresponds to the 48 test tube hole areas of the main frame 2. The pluggable movable base plate 6 is inserted into the slots 4. The upper and lower inner surfaces of the adjustment groove... A concave guide rail is provided along the diagonal direction of the main body frame 2. A fixing bolt 3 is provided at the position corresponding to the adjustment groove of the main body frame 2. The fixing bolt 3 is inclinedly threaded to the side wall of the main body frame 2. The bottom of the fixing bolt 3 is located in the adjustment groove and contacts the upper surface of the multi-hole plate 5. The upper and lower surfaces of the multi-hole plate 5 are provided with protruding guide rails along the diagonal direction. The protruding guide rails match the concave guide rails. The multi-hole plate 5 can slide along the concave guide rails. The silicone cover 1 is attached to the top of the main body frame 2. The bottom of the silicone cover 1 is provided with 5 fixing feet 101 that can be adapted to the fixing groove 201. The silicone cover 1 and the main body frame 2 are the same size. The right-angled wedge protrusion of the silicone cover 1 can be adapted to the test tube mouth of different diameters to achieve sealing.

[0016] The specific implementation process is as follows: First, according to the length of the test tube to be used, select the corresponding slot 4 at the bottom of the adjustment groove on the side wall of the main frame 2, insert the pluggable movable base plate 6 into the slot 4, and ensure that the base plate 6 is installed firmly to support the bottom of the test tube; the multi-hole plate 5 is located in the adjustment groove, and push the multi-hole plate 5 along the diagonal direction according to the diameter of the test tube until the diameter of the test tube hole matches the diameter of the test tube, and then tighten the fixing bolt 3 at the corresponding adjustment groove position of the main frame 2.
