Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a test tube rack that facilitates comparison. Background Technology

[0002] Test tube racks are common basic equipment used in laboratories of chemistry, biology, and medicine for placing, securing, and storing test tubes. Currently, the widely used traditional test tube racks have a relatively simple structure, typically consisting of two parallel flat plates connected by four corner supports. The upper plate has several positioning holes for inserting test tubes; after the test tubes pass through these holes, their bottoms rest directly against the lower plate, thus completing the placement.

[0003] However, this traditional structure has significant drawbacks. First, there is a gap between the limiting hole and the test tube, making it impossible to effectively clamp the test tube. Second, the bottom of the test tube makes rigid contact with the plate below, lacking cushioning. When the test tube rack is subjected to slight impacts, movement, or vibration of the work surface, the test tube will wobble within the holes and collide with surrounding test tubes, the hole walls, or the bottom plate, easily causing scratches, damage, or even breakage of the test tubes, especially glass test tubes. This not only results in the loss of experimental consumables but may also lead to safety hazards such as reagent leakage, contamination, and even personal injury. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a test tube rack that is easy to compare, so as to solve the problem that the existing test tube racks lack effective shock absorption and protection and the test tubes are easily broken due to vibration and collision.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A test tube rack for easy comparison includes: The storage box has a body and a lid; the top of the body is open and then sealed by the lid. The test tube rack unit includes a binding plate, a support column, and a pad. The binding plate has multiple holes arranged linearly and evenly in the left and right direction. The pad is fixedly connected to the bottom by the support column. After the test tube passes through the hole, the upper part is bound by the clamping and shock-absorbing structure set in the hole, and the bottom abuts against the pad. Multiple test tube rack units are arranged linearly and evenly along the front-to-back direction and then placed in a storage box. Adjacent test tube rack units can be detachably connected.

[0006] As an improvement, the clamping and shock-absorbing structure includes limiting slots, clamping rods, clamping heads, and elastic rope loops. Multiple limiting slots are evenly arranged circumferentially on the inner wall of the hole. Clamping rods are movably fitted within the limiting slots. Clamping heads are fixed to the ends of each clamping rod that are close to each other. The clamping heads are made of soft rubber. Each clamping rod has a pre-drilled hole at its close end, and the rods are then connected together by elastic rope loops. The test tube is clamped between the clamping heads, thus firmly holding the test tube.

[0007] As an improvement, the pad is made of EVA board. Combined with the aforementioned clamping and shock-absorbing structure, it can provide effective shock absorption for the test tube.

[0008] As an improvement, a dovetail groove is formed on the rear side of the binding plate. After the dovetail groove extends upward through the binding plate, dovetail inserts are formed on the front side of the binding plate corresponding to each dovetail groove. After the two test tube racks are assembled together and removed from the storage box, the control operation can be carried out more conveniently.

[0009] The advantages of this utility model compared with the prior art are as follows: 1. The core improvement of this new design lies in the inclusion of buffer structures at both the clamping and support points of the test tube. At the top of the test tube, a clamping and shock-absorbing structure composed of a soft rubber clamping head, a movable clamping rod, and an elastic rope loop adaptively grips test tubes of different diameters, effectively limiting their horizontal swaying. Simultaneously, the deformation of the elastic rope loop and soft rubber material absorbs vibration energy, preventing direct collisions between the test tube and the hard pore wall. At the bottom of the test tube, an EVA material pad is used. This material has high elasticity and cushioning properties, effectively mitigating impacts to the bottom of the test tube. This combined upper and lower buffering design provides all-around protection for the test tube, significantly reducing the risk of breakage due to vibration and collisions.

[0010] 2. This novel design utilizes multiple independently usable and combinable "test tube rack units," each capable of holding a group of related test tubes (such as all replicates of an experimental variable or a concentration gradient). The units are quickly and securely connected and separated via a clever structure of dovetail grooves and dovetail inserts, allowing researchers to clearly manage test tubes in groups, enabling intuitive control and observation, effectively preventing test tube misalignment, and greatly improving the organization and efficiency of experiments.

[0011] 3. This new design features a dedicated storage box and lid, allowing multiple connected test tube rack units to be stored together as a single, enclosed transport unit. Combined with the shoulder straps on the side of the box, the entire test tube assembly required for the experiment can be moved easily and safely. This makes it ideal for field sampling, teaching demonstrations, or transferring samples between different laboratories, avoiding the cumbersome and risky process of handling individual test tubes.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] A test tube rack for easy comparison mainly consists of a storage box and several individual test tube racks. The storage box includes a box body 1 and a box lid 2 for sealing the top opening of the box body. A shoulder strap 13 is installed on the side of the box body 1 for easy carrying or back carrying.

[0020] The test tube rack unit is a core functional component. In this embodiment, it is preferable to place five identical test tube rack units linearly arranged in the front-to-back direction within the housing 1. Each test tube rack unit includes a binding plate 3, several support columns 4, and a pad 5. The binding plate 3 is firmly connected to the pad 5 at the bottom via the vertically fixed support columns 4 below it, forming a stable frame structure. The pad 5 is preferably made of highly elastic and corrosion-resistant EVA (ethylene-vinyl acetate copolymer) foam board, providing soft support and effective cushioning for the bottom of the test tubes.

[0021] Five holes 6 are linearly and evenly distributed along the left-right direction on the binding plate 3 for inserting test tubes. Each hole 6 has a clamping and shock-absorbing structure inside.

[0022] The specific configuration of the clamping and shock-absorbing structure is as follows: Several (e.g., three or four) radial limiting slots 7 are uniformly machined along the circumferential direction on the inner wall of the hole 6. A clamping rod 8 is movably fitted into each limiting slot 7, and the clamping rod 8 can slide radially within the slot. A clamping head 9 is fixed to one end of each clamping rod 8 facing the center of the hole. This clamping head 9 is made of soft rubber (such as silicone), and is soft and elastic. A rope hole is provided at the end of each clamping rod 8 near the clamping head 9. An elastic rope loop (such as a latex ring or rubber band) 10 passes sequentially through the rope holes on all the clamping rods 8, connecting them together.

[0023] When the test tube (not shown in the figure) is inserted into the hole 6, the test tube wall pushes the clamping heads 9 outward, and the clamping rod 8 moves outward accordingly, stretching the elastic rope loop 10. At this time, the recoil force of the elastic rope loop 10 is transmitted to the clamping head 9 through the clamping rod 8, so that it evenly and gently hugs the test tube body from all sides. This structure can not only firmly clamp the test tube and prevent it from shaking, but also effectively absorb and offset the vibration and impact energy from the outside through the deformation of the elastic rope loop 10 and the soft rubber clamping head 9.

[0024] To facilitate rapid assembly and fixation of multiple test tube rack units, an upward-through dovetail groove 11 is machined on the rear side of the restraint plate 3. Correspondingly, on the front side of the restraint plate 3, at a position corresponding to the dovetail groove 11, a dovetail insert 12 is formed for precise insertion. When multiple test tube rack units need to be connected side by side, simply slide the dovetail insert 12 of one unit into the dovetail groove 11 on the rear side of the adjacent unit to achieve a secure connection, making the operation very simple. This connection method ensures that multiple units can be neatly arranged in the storage box or on the table, forming a whole, which is convenient for comparison and management.

[0025] The usage procedure of this utility model is as follows: First, according to the experimental grouping requirements, the experimenter inserts the associated test tubes into the holes 6 of the same test tube rack unit. The bottom of the test tube rests on the EVA pad 5, and the upper part is stably held by the shock-absorbing clamping structure. Then, multiple grouped test tube rack units are connected together using a dovetail groove structure to form a complete experimental group. Finally, all the connected test tube rack units are placed inside the storage box 1, and the box lid 2 is closed. The rack can then be safely carried to its destination or stored using the shoulder strap 13. Throughout the process, the test tubes remain under good shock-absorbing protection, and the grouping is clear and easy to compare.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
