[0002] Test tubes are commonly used containers in the field of sample testing. They are used to hold reagents and samples, and to process the samples placed inside. They are widely used in fields such as biology and chemistry. Taking biology as an example, test tubes are typically used to hold biological samples such as bodily fluids and blood, and reagents are added to the test tubes to process the biological samples for testing.

[0003] During transportation, test tubes often collide with each other in the test tube rack, causing them to break or even shatter, which affects procedures such as sampling and testing of the samples in the test tubes.

[0004] Therefore, there is a lack of test tube racks that can stably hold test tubes in place during transportation. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of test tube breakage caused by collision between the test tube rack and the test tube during transportation, and to provide a test tube storage rack.

[0009] An auxiliary clamping member is provided, one end of which is connected to the first clamping member and the other end of which is connected to the second clamping member. The movement of the auxiliary clamping member causes the first clamping member and the second clamping member to move so that the test tube placed in the receiving space through the through hole is clamped.

[0010] Preferably, the test tube storage rack further includes a support plate, which is disposed within the accommodating space and fixedly connected to the side wall of the mounting base.

Detailed Implementation

[0038] In this utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" are generally defined based on the specific orientation or positional relationship shown in the accompanying drawings. "Inner" and "outer" refer to the enclosed area surrounded by the component's outline and the space extending beyond that outline, respectively. "Far" and "near" are generally based on the core component or functional body as a reference point; "far" refers to a position farther from the reference point, and "near" refers to an area close to the reference point.

[0039] This embodiment provides a test tube storage rack 100, such as Figures 1-8 As shown, the test tube storage rack 100 includes a mounting base 10, a first clamping member 20, a second clamping member 30, and an auxiliary clamping member. The surface of the mounting base 10 is provided with a through hole 11 for accommodating test tubes. The interior of the mounting base 10 is provided with an accommodating space 14, and the through hole 11 connects to the accommodating space 14. The first clamping member 20 and the second clamping member 30 are both disposed within the accommodating space 14 and can move within the accommodating space 14. One end of the auxiliary clamping member is connected to the first clamping member 20, and the other end of the auxiliary clamping member is connected to the second clamping member 30. The movement of the auxiliary clamping member drives the first clamping member 20 and the second clamping member 30 to move so that the test tubes placed in the accommodating space 14 through the through hole 11 are clamped.

[0040] Through the above technical solution, the first and second clamping parts 30 are connected by an auxiliary clamping part to form a linkage mechanism, realizing bidirectional synchronous movement. When the auxiliary clamping part is subjected to force, the first and second clamping parts move towards the center or separate simultaneously, ensuring that the test tube is subjected to uniform force and avoiding tilting or breakage of the test tube caused by unilateral compression. Regardless of the diameter of the test tube, the first and second clamping parts 30 can adaptively adjust the spacing during movement, so that the axis of the test tube is always aligned with the axis of the through hole 11, improving the stability of the test tube placement and preventing the test tube from colliding with the mounting base 10 during movement, which would cause the test tube to break or be damaged. In addition, the limiting function of the through hole 11 prevents the test tube from tilting during vibration. It can adapt to test tubes of different diameters (such as 8-20mm in diameter) without manual adjustment and has good compatibility.

[0041] In this embodiment, the through holes 11 are arranged in a matrix on the surface of the mounting base 10, allowing for the placement of multiple rows and columns of test tubes. Specifically, it contains 125 test tube racks.

[0042] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the test tube storage rack 100 also includes a support plate 12, which is disposed in the accommodating space 14. In this embodiment, there are two support plates, which are symmetrically disposed in the accommodating space 14 of the mounting base 10. The two support plates 12 are respectively fixedly connected to the left side wall and the right side wall located inside the mounting base 10. The height of the support plate 12 is less than the height of the mounting base 10, and the gap between the support plate 12 and the upper and lower walls of the mounting base 10 is the same. Both the upper and lower surfaces of the support plate 12 are flat. The upper and lower ends of the first clamping member 20 are respectively attached to the upper end surface of the support plate 12 and the upper wall surface of the mounting base 10. The surface of the first clamping member 20 that is attached to the end surface of the support plate 12 is also flat, and the surface that is attached to the mounting base 10 is also flat. Similarly, the upper and lower ends of the second clamping member 30 are respectively attached to the lower end surface of the support plate 12 and the lower wall surface of the mounting base 10. The surface of the second clamping member 30 that is attached to the end surface of the support plate 12 is also flat, and the surface that is attached to the mounting base 10 is also flat. When the test tube needs to be clamped, the auxiliary clamping mechanism moves, causing the first clamping element 20 and the second clamping element 30 to move along the upper and lower surfaces of the support plate 12. The direction of movement is parallel to the left and right direction of the mounting base 10. The upper and lower inner walls of the two support plates 12 and the mounting base 10 provide support and limit for the first clamping element 20 and the second clamping element 30, allowing them to move left and right to clamp and release the test tube. The layered structure of the first clamping element 20 and the second clamping element 30 ensures that the clamping elements can only move in the horizontal direction, avoiding clamping failure due to vertical displacement. The support plate 12 acts as a guide rail for the clamping elements, ensuring that the first and second clamping elements 30 always move synchronously along a preset path.

[0043] In a preferred embodiment, such as Figure 2 , Figure 3As shown, the first clamping member 20 includes a first clamping body 21 and a first rack 22, with the first clamping body 21 fixedly connected to the first rack 22. The second clamping member 30 includes a second clamping body 31 and a second rack 32, with the second clamping body 31 fixedly connected to the second rack 32. An auxiliary clamping member drives the first rack 22 and the second rack 32 to move. The first rack 22 and the second rack 32 achieve opposite synchronous movement through an auxiliary clamping member (such as a set of gears 40), ensuring a uniform distribution of clamping force on the test tube by both clamping bodies. This reduces the risk of tilting caused by eccentric force on the test tube, improving clamping stability. The rack mechanism has high mechanical rigidity, effectively suppressing clamping loosening during transport vibrations or rapid operation, and has high control precision, with the displacement error of the rack drive controlled within ±0.2mm. The rack meshing length can be adjusted by the drive stroke of the auxiliary clamping member, supporting the clamping requirements of test tubes with diameters of 6-25mm. The auxiliary clamping component can be integrated with a lever or knob-driven rack, allowing for clamping / releasing actions with a single hand press. The rack engagement structure has a self-locking characteristic, maintaining the clamping state when no external force is applied.

[0044] In a preferred embodiment, the first clamping member 20 further includes a first bracket 23, and the first rack 22 is fixedly connected to the first clamping body 21 via the first bracket 23. The upper and lower end faces of the first bracket 23 are respectively attached to the inner wall of the mounting base 10 and the upper end face of the support plate 12. The second clamping member 30 further includes a second bracket 33, and the second rack 32 is fixedly connected to the second clamping body 31 via the second bracket 33. The upper and lower end faces of the second bracket 33 are respectively attached to the inner wall of the mounting base 10 and the lower end face of the support plate 12. The upper and lower end faces of the first bracket 23 and the second bracket 33 are also planar, which reduces the resistance to rack movement. The first bracket 23 and the second bracket 33 are respectively attached to the inner wall of the mounting base 10 and the upper and lower end faces of the support plate 12, forming a three-dimensional limiting structure. This design constrains the movement of the clamping components to the horizontal direction, avoiding clamping failure caused by vertical displacement. The symmetrical design of the first bracket 23 and the second bracket 33 enables the first clamping component 20 and the second clamping component 30 to form opposite synchronous movements through rack and pinion linkage, resulting in a uniform distribution of clamping force.

[0045] Among them, such as Figure 2 , Figure 3As shown, the first clamping member 20 includes five first brackets 23, each of which is provided with 25 first clamping bodies 21; similarly, the second clamping member 30 includes five second brackets 33, each of which is provided with 25 second clamping bodies 31; when the first clamping member 20 and the second clamping member 30 are assembled into the mounting base 10, the clamping surfaces of the first clamping bodies 21 and the second clamping bodies 31 are arranged opposite to each other, and the lower part of the first clamping body 21 and the upper part of the second clamping body 31 partially overlap in height, forming two complete semi-circular arc surfaces in the overlapping area, which together clamp and fix the test tube.

[0046] In a preferred embodiment, both the first clamping body 21 and the second clamping body 31 include arc-shaped clamping surfaces; the first clamping body 21 and the second clamping body 31 are arranged opposite to each other. The arc-shaped clamping surfaces form surface contact with the cylindrical outer wall of the test tube, dispersing stress and protecting the test tube. Compared with flat clamping, this method can accommodate test tubes with larger diameter spans (e.g., 6-30mm). The arc-shaped clamping bodies can also be coated with silicone or polyurethane, increasing the coefficient of friction to 0.8-1.2, maintaining clamping stability during transportation vibrations, and providing a cushioning effect for the test tube.

[0047] In a preferred embodiment, such as Figure 6 As shown, the test tube storage rack 100 also includes a gear 40, which is fixedly connected to the mounting base 10. One end of the gear 40 is rotatably connected to a first rack 22, and the other end is rotatably connected to a second rack 32. The gear 40 rotates so that the first rack 22 and the second rack 32 move in opposite directions. The gear 40 meshes with the first rack 22 and the second rack 32, driving them to move synchronously in opposite directions. This ensures that the clamping force of the clamping bodies on both sides is evenly distributed on the test tubes, reducing the risk of tilting caused by eccentric force on the test tubes and improving clamping stability. The rack stroke of the gear 40 is adjustable, supporting the clamping requirements of test tubes with diameters of 5-30mm. The gear 40, rack, and clamping bodies are connected separately, and can be replaced individually after wear, resulting in low maintenance costs.

[0048] In a preferred embodiment, such as Figure 5 , Figure 7 As shown, the test tube storage rack 100 also includes a mounting plate 50, which is fixedly connected to the support plate 12. A rotating shaft 51 is mounted on the mounting plate 50, and the gear 40 is rotatably connected to the rotating shaft 51. The mounting plate 50, fixed to the support plate 12, forms a composite support structure, providing a stable base for the gear 40 to rotate, reducing the vibration amplitude of the gear 40 by approximately 30%, and effectively suppressing rack displacement caused by transportation vibration. The mounting plate 50, as an independent module, supports quick assembly and disassembly of the gear 40 assembly. Only a single module needs to be replaced after the gear 40 wears out, resulting in low maintenance costs.

[0049] In a preferred embodiment, the support plate 12 has a recessed portion to facilitate the mounting plate 50 being installed on it. A mounting post 122 is disposed within the recessed portion. The mounting plate 50 has a positioning hole 52, which passes through the mounting post 122. The mounting plate 50 is fixed to the mounting post 122 via the positioning hole 52, facilitating the relative fixing and disassembly of the mounting plate 50 and the support plate 12. Furthermore, the mounting plate 50 and the support plate 12 are separately connected via the positioning hole 52, allowing for individual replacement after wear, thus reducing operating costs.

[0050] In a preferred embodiment, the first clamping member 20 further includes a first mounting post 24 and a first elastic member 25. The two ends of the first elastic member 25 are respectively connected to the inner walls of the first mounting post 24 and the mounting base 10, providing an initial driving force for the first rack 22 and preventing the first rack 22 from moving beyond a predetermined position. The second clamping member 30 further includes a second mounting post 34 and a second elastic member 35. The two ends of the second elastic member 35 are respectively connected to the inner walls of the second mounting post 34 and the mounting base 10, providing an initial driving force for the movement of the second rack 32 and preventing the second rack 32 from moving to a predetermined position. The first elastic member 25 and the second elastic member 35 are diagonally arranged. The diagonal arrangement of the first elastic member 25 and the second elastic member 35 forms a symmetrical couple structure.

[0051] In a preferred embodiment, the test tube storage rack 100 further includes a dial 60. The mounting base 10 has a side hole 13 on the side opposite to the auxiliary clamping member. The dial 60 is rotatably connected to the side hole 13. The dial 60, located on the side, can integrate scale markings. Specifically, as... Figure 1 , Figure 4 , Figure 8 As shown, the side is provided with three dials 60 and a dial cover 61. The dials 60 are assembled to the side of the mounting base 10 by pins. The dial cover 61 covers part of the surface of the dials 60 and is also fixed to the side by threads, etc. By rotating the three dials 60, the function of recording and archiving can be achieved.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
