Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, and in particular to a novel chemical test tube rack. Background Technology

[0002] In chemical experiments, test tube racks are essential experimental equipment used to hold test tubes, facilitating experimental operations and management.

[0003] Chinese Patent No. CN208356851U discloses a test tube rack for chemical experiments, including a base plate, a frame plate, and placement columns. Columns are respectively provided on the rear portions of both sides of the top surface of the base plate. Multiple hemispherical grooves are spaced apart on the top surface of the base plate between the two columns. Through holes B are provided on both sides of the frame plate, and multiple through holes A are spaced apart between two through holes B. Two through holes B are respectively fitted onto the middle sections of the two columns. Multiple through holes A correspond to multiple hemispherical grooves. Multiple screw holes are spaced apart on the front portion of the top surface of the base plate. The placement column includes a screw A, a sleeve, and a base. The screw A has external threads, and the sleeve has a cavity with internal threads on its sidewall. A downward-extending screw B is located at the center of the bottom of the base. A rubber sleeve is fitted onto the lower end of the sleeve, and the lower end of the sleeve with the rubber sleeve is fixedly connected to the upper end of the base. The lower end of the screw A extends into the cavity and is screwed into the sleeve. The screw B is screwed into the screw holes.

[0004] Existing technologies have several shortcomings: First, their fixed structure prevents flexible adjustments to the number of test tube racks based on experimental needs, potentially leading to excessive space occupation or insufficient test tube placement, resulting in low space utilization efficiency. Second, the methods for fixing test tubes are limited and cannot accommodate test tubes of varying diameters. Therefore, we propose a novel chemical test tube rack. Utility Model Content

[0005] The main purpose of this invention is to propose a novel chemical test tube rack that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel chemical test tube rack, comprising:

[0007] Base;

[0008] Two extension seats are slidably disposed within the base and are symmetrically distributed.

[0009] A plurality of mounting slot groups are disposed on the upper surface of the base and the extension base and are distributed in an equidistant array. Each mounting slot group includes two mounting slots symmetrically distributed along the transverse axis of the base.

[0010] A test tube rack is provided between two mounting slots. The bottom of the test tube rack is fixed with two pins that are compatible with the mounting slots. The test tube rack is provided with multiple placement slots.

[0011] Four spring clips are evenly and fixedly arranged on the wall of the placement groove, and the spring clips are used to fix the test tube.

[0012] As a further description of the above technical solution, the spring sheet has an inclined portion and a vertical portion.

[0013] As a further description of the above technical solution, two symmetrically distributed positioning bolts are provided on one side wall of the base, and multiple threaded grooves adapted to the positioning bolts are provided on the expansion base.

[0014] As a further description of the above technical solution, dovetail blocks are fixedly provided on both sides of the mounting groove, and dovetail grooves adapted to the dovetail blocks are opened on both sides of the pin.

[0015] As a further description of the above technical solution, a first magnet is fixedly embedded in the bottom of the mounting groove, and a second magnet that cooperates with the first magnet is fixedly embedded in the bottom wall of the pin.

[0016] As a further description of the above technical solution, a transparent label box is fixedly provided on one side wall of the test tube rack.

[0017] As a further description of the above technical solution, the base is provided with anti-slip feet at the four corners of its bottom wall.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. With the addition of expansion seats, the number of test tube racks can be flexibly increased or decreased according to actual experimental needs. When conducting large-scale experiments, more test tube racks can be added to meet the need for more test tubes, while when the scale of the experiment is small, the number of test tube racks can be reduced, effectively saving experimental table space and improving space utilization.

[0020] 2. The spring clips can adaptively clamp test tubes of different sizes, ensuring the stability of the test tubes after they are placed in the test tube rack.

[0021] 3. Each test tube rack has a separate transparent label box, which facilitates the classification and management of test tubes. Operators can place test tubes with different uses and containing different reagents on the test tube rack with the corresponding labels, which is convenient for quick identification and use and effectively avoids reagent confusion.

[0029] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0030] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-6 This utility model provides a novel chemical test tube rack, including a base 1, two expansion seats 2, several mounting slots, a test tube rack 4, and four spring clips 5. Through the above structure, the test tube rack 4 can be flexibly added or removed, improving space utilization, and can fix test tubes of different diameters, making it highly applicable.

[0033] To further explain, the two expansion seats 2 are slidably disposed within the base 1 and are symmetrically distributed. Several mounting slots are disposed on the upper surfaces of the base 1 and the expansion seats 2 and are distributed in an equidistant array. The mounting slots include two mounting slots 3 symmetrically distributed along the transverse axis of the base 1. The test tube rack 4 is disposed between the two mounting slots 3. The bottom of the test tube rack 4 is fixedly provided with two pins 41 that are adapted to the mounting slots 3. The test tube rack 4 is provided with multiple placement slots 42. Four spring pieces 5 are evenly fixedly ringed on the slot wall of the placement slot 42. The spring pieces 5 are used to fix the test tubes.

[0034] To further explain, the spring 5 has an inclined part 51 and a vertical part 52, which can adaptively clamp test tubes of different sizes and ensure the stability of the test tubes after they are placed in the test tube rack 4.

[0035] To further explain, the base 1 has anti-slip feet at the four corners of its bottom wall, which can increase the friction between the base 1 and the test bench, making it less prone to slipping and more stable. The base 1 has two symmetrically distributed positioning bolts 6 on one side wall, and the expansion seat 2 has multiple threaded grooves 21 that are compatible with the positioning bolts 6. The positioning bolts 6 are screwed into different threaded grooves 21 to position the expansion seat 2.

[0036] To further explain, dovetail blocks 31 are fixedly provided on both sides of the mounting groove 3, and dovetail grooves 411 that are compatible with the dovetail blocks 31 are provided on both sides of the plug 41, which improves the insertion effect between the plug 41 and the mounting groove 3 and prevents the test tube rack 4 from shaking.

[0037] To further explain, a first magnet 32 ​​is fixedly embedded in the bottom of the mounting groove 3, and a second magnet 412 that cooperates with the first magnet 32 ​​is fixedly embedded in the bottom wall of the plug 41. After the plug 41 is inserted into the mounting groove 3, the first magnet 32 ​​and the second magnet 412 attract each other, thus completing the installation of the test tube rack 4. When disassembling, simply pull the test tube rack 4 to overcome the magnetic attraction, and the disassembly can be completed. The disassembly and assembly are relatively convenient.

[0038] To further explain, a transparent label box 43 is fixedly installed on one side wall of the test tube rack 4. The transparent label box 43 provides convenience for the classification and management of test tubes. Operators can place test tubes with different uses and containing different reagents on the test tube rack 4 with corresponding labels, which is convenient for quick identification and use and effectively avoids reagent confusion.

[0039] It should be noted that this utility model is a novel chemical test tube rack. In use, the pins 41 of the test tube rack 4 are inserted into the mounting slot 3, so that the first magnet 32 ​​and the second magnet 412 attract each other, thus completing the installation of the test tube rack 4. Then, a label is used to indicate what type of test tube the test tube rack 4 is used to hold, and the label is inserted into the transparent label box 43. Then, the test tube is placed into the placement slot 42 on the test tube rack 4. The test tube will squeeze the inclined part 51 of the spring piece 5, causing the spring piece 5 to undergo elastic deformation. When the test tube is fully inserted, the vertical part 52 of the spring piece 5 clamps the test tube. When there are not enough test tube racks 4 on the base 1, the positioning bolts 6 can be unscrewed, and then the extension seat 2 can be pulled out of the base 1. Then, the positioning bolts 6 are screwed into the corresponding threaded groove 21 to fix the extension seat 2. The test tube rack 4 can be removed and installed in the mounting slot 3 on the extension seat 2 to complete the expansion of the test tube rack 4, which is more flexible.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
