Description

Technical Field

[0001] The embodiments of this utility model belong to the field of test tube adapter technology, and more specifically, relate to an adapter for test tubes of different specifications. Background Technology

[0002] With modern residents increasingly focused on health, the number of physical examinations they participate in is also rapidly growing. A significant portion of these examinations require test tubes, and the types and specifications of test tubes used vary depending on the specific test. In particular, there are test tubes specifically designed for storing various types of capillary blood; these tubes are smaller in diameter and shorter in length than common test tubes. After sampling, these test tubes must be placed on test tube racks for storage. However, in most scenarios, due to the diverse specifications of these test tubes, there are no dedicated test tube racks available. Furthermore, during testing, it may be necessary to place test tubes from different capillary blood collection points on the same rack for simultaneous testing, and general-purpose test tube racks are incompatible with these tubes.

[0003] The commonly used method is to attach an adapter to the bottom of a small test tube, the length and diameter of which correspond to the pre-defined positions on the test tube rack. The test tube with the adapter is then placed on the rack, allowing test tubes of different sizes to be stored on the same rack for testing simultaneously. While this method solves the problem of inconsistent test tube sizes, it requires the adapter's internal cavity to accommodate different test tubes, necessitating the preparation of adapters of varying sizes, which causes considerable inconvenience.

[0004] Therefore, an adapter is needed for test tubes of different sizes to improve the versatility of the adapter. This would eliminate the need to manufacture adapters of various sizes, allowing the use of a single adapter to adapt to test tubes of different dimensions. Utility Model Content

This allows different small test tubes to be placed on the same type of test tube rack for testing, simplifies the testing process, and makes it easier for testing personnel to operate.

[0006] To achieve the above objectives, this utility model provides an adapter for test tubes of different specifications, including a fixed inner tube and a rotating outer tube;

[0007] The rotating outer tube is fitted over the fixed inner tube, and the two are rotatably connected.

[0008] The fixed inner tube is also provided with a lifting plate, and the lifting plate passes through the fixed inner tube and is connected to the rotating outer tube. When the rotating outer tube rotates, it drives the lifting plate to move axially in the fixed inner tube.

[0009] Multiple elastic plates are provided at the internal opening of the fixed inner tube.

[0010] Furthermore, the fixed inner tube has two opposing lifting grooves on its wall. These lifting grooves are arranged along the axial direction of the fixed inner tube and connect the inner cavity of the fixed inner tube with the inner cavity of the rotating outer tube.

[0011] Furthermore, the inner wall of the rotating outer tube is provided with double helical grooves with equal spacing on both sides as a lifting and pushing track, and the position of the bottom of the lifting and pushing track corresponds to the position of the bottom of the lifting groove.

[0012] Furthermore, the lifting plate includes a support plate disposed in the inner cavity of the fixed inner tube, and a bearing plate disposed on the support plate.

[0013] Furthermore, the pallet is a cylindrical thin plate with the same diameter as the inner diameter of the fixed inner tube. The bearing plates are arranged in pairs and symmetrically on the cylindrical surface of the pallet, and their width is the same as that of the lifting groove and the lifting push rail.

[0014] Furthermore, after the support plate passes through the lifting groove, its end extends into the lifting push rail, and the ends of the two support plates are respectively placed in the lifting push rail.

[0015] Furthermore, the center of the tray is provided with a groove, which is spherical and its bottom completely penetrates the tray. A buffer layer is also provided along the surface of the groove.

[0016] Furthermore, the top of the rotating outer tube is provided with a rotating head, and the top of the fixed inner tube is provided with a fixed head. The rotating outer tube and the fixed inner tube are rotatably connected through the rotating head and the fixed head.

[0017] Furthermore, the diameter of the fixed head is larger than that of the fixed inner tube, and an annular groove is provided at the junction with the fixed inner tube. The top of the rotating outer tube is provided with an annular protrusion, and the annular protrusion is embedded in the annular groove to form a structure in which they are interlocked and rotate.

[0018] Furthermore, the top of the elastic plate is fixed to the opening of the fixed inner tube, and there are at least three equidistantly arranged elastic plates. The elastic plates are inclined and their bottoms are close to the center of the fixed inner tube.

[0019] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0020] 1. This utility model is an adapter for test tubes of different specifications. It can adaptively adjust the length and diameter of the tubes to meet the specifications of different test tubes, improve the versatility of the adapter, and enable the use of one adapter to adapt to a large number of small test tubes of different specifications. Different small test tubes can be placed on the same type of test tube rack for testing at the same time, which simplifies the testing process and makes it easier for testing personnel to operate.

[0021] 2. This utility model is an adapter for test tubes of different specifications. The buffer layer on the tray protects the test tube from damage, and the bottom of the test tube is initially positioned within the tray, ensuring it is centered on the inner tube. For test tubes with a conical bottom, the bottom of the test tube passes precisely through the through hole at the bottom of the tray and is then confined within it.

[0022] 3. This utility model is an adapter for test tubes of different specifications. When the test tube to be tested is placed in the fixed inner tube, its bottom pushes the elastic plate to move away from the center of the fixed inner tube, causing deformation and allowing the test tube to smoothly enter the fixed inner tube. After the test tube is smoothly placed in the fixed inner tube, the elastic plate, due to its elasticity, always adheres to the outer wall of the test tube and exerts a pushing force on it to fix the test tube and prevent it from shaking.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1-3 As shown, this utility model embodiment provides an adapter for test tubes of different specifications, including a fixed inner tube 1 and a rotating outer tube 2. The rotating outer tube 2 is fitted over the fixed inner tube 1, and the two are rotatably connected. A lifting plate 4 is also provided inside the fixed inner tube 1, and the lifting plate 4 passes through the fixed inner tube 1 and connects to the rotating outer tube 2. When the rotating outer tube 2 rotates, it drives the lifting plate 4 to move axially within the fixed inner tube 1, changing its depth to accommodate various test tube lengths. Multiple elastic plates 8 are provided at the inner opening of the fixed inner tube 1, supporting the test tubes inside the fixed inner tube 1 to accommodate various test tube diameters. Simultaneously, adaptive adjustment of length and diameter is performed to meet the specifications of different test tubes, improving the adapter's versatility. This allows for the adaptation of a large number of small test tubes of different specifications using a single adapter, enabling the simultaneous placement of different small test tubes on the same type of test tube rack for testing, simplifying the testing process and facilitating operation for testing personnel.

[0032] The fixed inner tube 1 has two opposing lifting grooves 3 on its wall. The lifting grooves 3 are arranged along the axial direction of the fixed inner tube 1 and connect the inner cavity of the fixed inner tube 1 to the inner cavity of the rotating outer tube 2. The inner wall of the rotating outer tube 2 is provided with double helical grooves with equal spacing on both sides as lifting and pushing tracks 5. The bottom position of the lifting and pushing tracks 5 corresponds to the bottom position of the lifting grooves 3.

[0033] The lifting plate 4 includes a support plate 41 disposed within the inner cavity of the fixed inner tube 1, and a bearing plate 42 disposed on the support plate 41. The support plate 41 is a cylindrical thin plate with a diameter identical to the inner diameter of the fixed inner tube 1. The bearing plates 42 are arranged in pairs and symmetrically on the cylindrical surface of the support plate 41, and their width is the same as that of the lifting groove 3 and the lifting drive rail 5. After passing through the lifting groove 3, the bearing plates 42 extend at their ends into the lifting drive rail 5, with the ends of the two bearing plates 42 respectively positioned within the lifting drive rail 5.

[0034] As a further preferred embodiment, a small gap is left between the fixed inner tube 1 and the rotating outer tube 2 to avoid friction when they rotate.

[0035] Understandably, when it is necessary to adapt the test tube to the test tube, the outer tube 2 is rotated according to the length of the test tube, and the lifting and lowering push rail 5 on its inner wall pushes the support plate 42 to move up and down.

[0036] As a further preferred embodiment, the center of the tray 41 is provided with a groove 43, which is spherical and its bottom completely penetrates the tray 41. A buffer layer, preferably a rubber layer, is also provided along the surface of the groove 43. After the tray 41 is adjusted to a suitable height, the test tube to be tested is placed in the fixed inner tube 1, with the bottom of the test tube resting on the groove 43. The buffer layer protects the test tube from damage. The bottom of the test tube is also initially positioned within the groove 43, ensuring that its bottom is centered within the fixed inner tube 1. For test tubes with a conical bottom, the bottom of the test tube passes precisely through the through hole at the bottom of the groove 43 and is then confined within the groove 43.

[0037] The rotating outer tube 2 has a rotating head 7 at its top, and the fixed inner tube 1 has a fixed head 6 at its top. The rotating outer tube 2 and the fixed inner tube 1 are rotatably connected by the rotating head 7 and the fixed head 6. The diameter of the fixed head 6 is larger than that of the fixed inner tube 1, and an annular groove is provided at the junction with the fixed inner tube 1. The top of the rotating outer tube 2 has an annular protrusion, which is embedded in the annular groove to form a mutually interlocking and rotating structure.

[0038] As a further preferred embodiment, the top of the elastic plate 8 is fixed to the opening of the fixed inner tube 1, and at least three are equidistantly arranged. The elastic plate 8 is inclined, with its bottom close to the center of the fixed inner tube 1. When the test tube to be tested is placed into the fixed inner tube 1, its bottom pushes the elastic plate 8 to move away from the center of the fixed inner tube 1, causing deformation and allowing the test tube to smoothly enter the fixed inner tube 1. After the test tube is successfully placed into the fixed inner tube 1, the elastic plate 8, due to its elasticity, always adheres to the outer wall of the test tube and exerts a pushing force on it to fix the test tube and prevent it from shaking.

[0039] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
