Abstract

This utility model relates to the field of centrifuge tube adapters, specifically a microcentrifuge tube adapter and capping machine. The adapter has a front groove, a rear groove, and an outwardly expanding hole on its surface, and an inner through hole in its inner cavity. The width of the front groove is 2.8~6.8mm, and the depth of the front groove is 3~7mm. This utility model secures the microcentrifuge tubes by placing them inside the inner through hole at the top of the adapter. The adapter is then placed inside a placement box, which is pushed to the bottom of the pressure plate. The rotating pressure rod is then held, causing the connecting rod and gear to rotate together. The gear then drives the first connecting block of the gear column to move the pressure plate downwards, squeezing and simultaneously closing the caps of multiple microcentrifuge tubes inside the adapter. This eliminates the need for operators to individually cap the microcentrifuge tubes, reducing finger damage, and allows for more efficient capping of multiple tubes at once.

Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube adapters, specifically to microcentrifuge tube adapters and capping machines. Background Technology

[0002] Centrifuge tubes are tubular sample containers used for centrifugation operations, usually with a sealing cap or a compression cap, while microcentrifuge tubes are small centrifuge tubes, also known as EP (Eppendorf) tubes, used with microcentrifuges for the separation and centrifugation of trace reagents. In the existing technology, microcentrifuge tubes are a common tool for centrifugation operations in the laboratory, used to separate, precipitate or concentrate different components in samples. In order to secure the cap of the microcentrifuge tube during the experimental operation, the cap is usually pressed with a finger. However, this method is not only easy to damage the fingers, but also inefficient, as only one microcentrifuge tube can be pressed at a time. Moreover, the microcentrifuge tubes are small and inconvenient to fix. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, microcentrifuge tubes are usually capped securely during experimental operations by pressing them with fingers. However, this method is not only prone to causing finger injuries, but also inefficient, as only one microcentrifuge tube can be capped at a time. Furthermore, the small size of the microcentrifuge tubes makes them difficult to secure. This invention proposes a microcentrifuge tube adapter and capping machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a microcentrifuge tube adapter, including an adapter, wherein the surface of the adapter is provided with a front groove, a rear groove and an outer expansion hole, and the inner cavity of the adapter is provided with an inner through hole.

[0005] Preferably, the width of the front groove is 2.8~6.8mm, the depth of the front groove is 3~7mm, and the length of the front groove is 4~8mm.

[0006] Preferably, the width of the front groove is 4.8 mm, the depth of the front groove is 5 mm, the length of the front groove is 6 mm, and the radius of the front groove is 1.25.

[0007] Preferably, the depth of the rear groove is 0.5~4.5mm, the diameter of the rear groove is 11~15mm, the diameter of the outer expansion hole is 11~15mm, and the height of the outer expansion hole is 0.5~4.5mm.

[0008] Preferably, the depth of the rear groove is 2.5 mm, the diameter of the rear groove is 13 mm, the diameter of the outer expansion hole is 13 mm, the height of the outer expansion hole is 2.5 mm, and the diameter of the inner through hole is 11 mm.

[0009] Preferably, the adapter has a fifth hollow groove on its surface, and a rubber block is fixedly connected to the inner cavity of the fifth hollow groove.

[0010] This utility model also provides a micro-centrifuge tube capping machine, including a base plate located at the bottom of an adapter. A placement box is slidably connected to the top of the base plate, and the adapter is located inside the placement box. A support column is fixedly connected to the top of the base plate, and a fixing block is fixedly connected to the top of the support column. A first hollow groove is formed on the surface of the fixing block, and a toothed column is slidably connected to the inner cavity of the first hollow groove. A first connecting block is fixedly connected to the bottom of the toothed column, and a pressure plate is fixedly connected to the bottom of the first connecting block. A second hollow groove is formed in the inner cavity of the fixing block, and a gear is rotatably connected to the inner cavity of the second hollow groove. The teeth of the gear mesh with the teeth of the toothed column. A third hollow groove is formed on the surface of the fixing block, and a connecting rod is rotatably connected to the inner cavity of the third hollow groove. One side of the connecting rod is fixedly connected to one side of the gear, and a pressure rod is fixedly connected to the surface of the connecting rod.

[0011] Preferably, the inner cavity of the fixing block is provided with a fourth hollow groove, and a second connecting block is slidably connected to the inner cavity of the fourth hollow groove. One side of the second connecting block is fixedly connected to the surface of the tooth column, and a spring is fixedly connected to the bottom of the second connecting block. The bottom of the spring is fixedly connected to the inner cavity of the fourth hollow groove.

[0012] Preferably, the surface of the base plate is provided with a guide groove, and a guide rod is slidably connected to the inner cavity of the guide groove. The top of the guide rod is fixedly connected to the bottom of the placement box.

[0013] The advantages of this utility model are: This invention secures the microcentrifuge tubes by placing them inside the through-hole at the top of the adapter. The adapter is then placed inside a storage box, which is pushed to the bottom of the pressure plate. The rotating lever is then held, causing the connecting rod and gear to rotate together. The gear drives the first connecting block of the gear column, which in turn moves the pressure plate downwards, pressing down on the caps of multiple microcentrifuge tubes inside the adapter and closing them simultaneously. This eliminates the need for operators to individually press the caps on each microcentrifuge tube, reducing finger injury. Furthermore, pressing multiple tubes at once is more efficient. It solves the problem that in experimental operations, microcentrifuge tubes are typically capped by pressing with fingers, which is not only prone to finger injury but also inefficient, allowing only one tube to be pressed at a time, and the small size of the tubes makes them difficult to secure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail. This application discloses a microcentrifuge tube adapter. (Refer to...) Figure 1-2A microcentrifuge tube adapter includes an adapter 3. The adapter 3 has a front groove 20 on its surface to hold the connecting plastic between the microcentrifuge tube and the tube cap, a rear groove 21 to accommodate the flange of the cap head and to allow the cap to be opened with the assistance of a bottle opener, an outer expansion hole 22 to hold the neck of the microcentrifuge tube, and an inner through hole 23 in the inner cavity of the adapter 3 to accommodate and fix the microcentrifuge tube body. The front groove 20, rear groove 21, outer expansion hole 22 and inner through hole 23 are all provided on the top of the adapter 3, and each can hold one microcentrifuge tube. This allows multiple microcentrifuge tubes to be placed on the upper side of the adapter 3. When in use, the adapter 3 is placed inside the placement box 2 for easy movement. The adapter 3 can be placed inside the capping machine, allowing multiple microcentrifuge tubes to be capped at once. This is not only more convenient and efficient, but also eliminates the need for manual capping, preventing finger injuries. Furthermore, the spacing between each adjacent front groove 20, rear groove 21, outer expansion hole 22, and inner through hole 23 is designed according to a laboratory eight-row pipette, ensuring compatibility and improved pipetting efficiency. The front groove 20, rear groove 21, outer expansion hole 22, and inner through hole 23 can be made into different sizes and shapes to accommodate microcentrifuge tubes of varying sizes. The centrifuge tubes are compatible with most brands of microcentrifuge tubes, such as 0.2ml, 0.5ml, 0.6ml, 0.65ml, and 1.5ml microcentrifuge tubes. The front groove 20 has a width of 4.8mm, a depth of 5mm, a length of 6mm, and a corner radius of 1.25. The rear groove 21 has a depth of 2.5mm and a diameter of 13mm. The outer expansion hole 22 has a diameter of 13mm and a height of 2.5mm. The inner through hole 23 has a diameter of 11mm.

[0019] Reference Figure 2 The width of the front groove 20 is 2.8~6.8mm, the depth of the front groove 20 is 3~7mm, and the length of the front groove 20 is 4~8mm.

[0020] Reference Figure 2 The width of the front groove 20 is 4.8mm, the depth of the front groove 20 is 5mm, the length of the front groove 20 is 6mm, and the radius of the front groove 20 is 1.25.

[0021] Reference Figure 2 The depth of the rear groove 21 is 0.5~4.5mm, the diameter of the rear groove 21 is 11~15mm, the diameter of the outer expansion hole 22 is 11~15mm, and the height of the outer expansion hole 22 is 0.5~4.5mm.

[0022] Reference Figure 2The depth of the rear groove 21 is 2.5mm, the diameter of the rear groove 21 is 13mm, the diameter of the outer expansion hole 22 is 13mm, the height of the outer expansion hole 22 is 2.5mm, and the diameter of the inner through hole 23 is 11mm.

[0023] Reference Figure 1 The surface of the adapter 3 is provided with a fifth hollow groove 24. A rubber block 25 is fixedly connected to the inner cavity of the fifth hollow groove 24. The interior of the fifth hollow groove 24 can be used to place the rubber block 25, so that the bottom of the adapter 3 can be connected to the rubber block 25. The rubber block 25 has a large friction force, so that the adapter 3 can be more stable and less prone to movement when placed inside the placement box 2.

[0024] Reference Figures 3-5 This application also provides a microcentrifuge tube capping machine, including a base plate 1, which is located at the bottom of an adapter 3. A placement box 2 is slidably connected to the top of the base plate 1, and the adapter 3 is located in the inner cavity of the placement box 2. A support column 4 is fixedly connected to the top of the base plate 1, and a fixing block 5 is fixedly connected to the top of the support column 4. A first hollow groove 7 is opened on the surface of the fixing block 5. A toothed column 8 is slidably connected to the inner cavity of the first hollow groove 7. A first connecting block 9 is fixedly connected to the bottom of the toothed column 8. A pressure plate 6 is fixedly connected to the bottom of the first connecting block 9. A second hollow groove 10 is opened in the inner cavity of the fixing block 5. A gear 11 is rotatably connected to the inner cavity of the second hollow groove 10. The teeth of the gear 11 mesh with the teeth of the toothed column 8. A third hollow groove 12 is opened on the surface of the fixing block 5. A connecting rod 13 is rotatably connected to the inner cavity of the third hollow groove 12. One side of the connecting rod 13 is fixedly connected to one side of the gear 11. A pressure rod 14 is fixedly connected to the surface of the connecting rod 13. The upper side of the base plate 1 can be used to place the placement box 2, allowing the placement box 2 to slide. The interior of the placement box 2 can be used to place the adapter 3, and the interior of the adapter 3 can be used to place multiple microcentrifuge tubes. The support column 4 can be used to support the fixing block 5, and the second hollow groove 10 inside the fixing block 5 can be used to place the gear 11. The interior of the first hollow groove 7 can be used to place the gear 8, and the gear 8 meshes with the gear 11, so that when the gear 11 rotates, it can drive the gear 8 to move up and down. The first connecting block 9 can be used to connect the gear 8 and the pressure plate 6, so that when the gear 8 moves, it can drive the pressure plate 6 to move down together. The pressure plate 6 is located on the upper side of the adapter 3, and the downward pressure of the pressure plate 6 can simultaneously close the tube caps of multiple microcentrifuge tubes inside the adapter 3. The pressing mechanism eliminates the need for researchers to individually press the caps on the microcentrifuge tubes, reducing finger damage. Pressing multiple tubes at once is also more efficient. The adapter 3 can be removed from the placement box 2 to accommodate microcentrifuge tubes of different sizes, allowing for greater compatibility. The third hollow slot 12 can house the connecting rod 13, enabling it to connect to the gear 11. The pressure rod 14 is attached to the surface of the connecting rod 13 and forms an L-shape with it, facilitating rotation to drive the gear 11. This makes the rotation of the gear 11 and the downward movement of the gear column 8 more convenient.

[0025] Reference Figure 4 The inner cavity of the fixing block 5 is provided with a fourth hollow groove 15. The inner cavity of the fourth hollow groove 15 is slidably connected to a second connecting block 16. One side of the second connecting block 16 is fixedly connected to the surface of the gear column 8. The bottom of the second connecting block 16 is fixedly connected to a spring 17. The bottom of the spring 17 is fixedly connected to the inner cavity of the fourth hollow groove 15. The interior of the fourth hollow groove 15 can be used to place the second connecting block 16. The second connecting block 16 can limit the gear column 8, making it difficult for the gear column 8 to rotate inside the first hollow groove 7, thereby ensuring meshing with the gear 11. The spring 17 can be compressed by the moving gear column 8 and the second connecting block 16. When the gear column 8 drives the pressure plate 6 to press, the spring 17 can bounce the gear column 8 upward and reset it through elastic force.

[0026] Reference Figure 3 The surface of the base plate 1 is provided with a guide groove 18. A guide rod 19 is slidably connected to the inner cavity of the guide groove 18. The top of the guide rod 19 is fixedly connected to the bottom of the placement box 2. The inside of the guide groove 18 can be used to place the guide rod 19 and guide the placement box 2 through the guide rod 19, so that the placement box 2 is not easy to shift on the upper side of the base plate 1, and can be stabilized on the lower side of the pressure plate 6.

[0027] Working Principle: When using this device, first place the microcentrifuge tube inside the inner through hole 23 on the top of the adapter 3, ensuring the tube body is inside the inner through hole 23. Then, place the neck of the microcentrifuge tube inside the outer expansion hole 22. The tube body and cap are connected by a flexible plastic connector, which is secured in the front groove 20 to prevent the tube body from rotating or moving, while the cap is in an upright position. Place the front groove 20 towards the capping machine's pushing direction on the placement box 2, then push the placement box 2 to move it above the base plate 1 and to the bottom of the pressure plate 6. The distance between the bottom surface of the pressure plate 6 and the upper surface of the adapter 3 is designed to be slightly higher than the tube opening but lower than the height of the upright cap. During the movement of the placement box 2, the pressure plate 6 pushes the cap towards the top of the microcentrifuge tube opening. After pushing the placement box 2 completely under the pressure plate 6, grasp the pressure rod 14 and rotate it. The pressure rod 14 will drive the connecting rod 13 and the gear 11 to rotate together. Then, the gear 11 will drive the gear column 8 to move downwards. At the same time, the gear column 8 will drive the second connecting block 16 to move together. The second connecting block 16 will compress the spring 17 to retract. As the gear column 8 moves, it will also drive the pressure plate 6 to move downwards through the first connecting block 9. Then, the pressure plate 6 will press and close the caps of the multiple microcentrifuge tubes inside the adapter 3 simultaneously, eliminating the need for the experimenter to manually close each microcentrifuge tube individually. The capping of the microcentrifuge tubes is pressed down, reducing damage to the fingers and increasing efficiency by pressing multiple tubes at once. The internal compartment of the housing 2 can also hold adapters 3 with slots of different sizes, allowing for the placement and pressing of microcentrifuge tubes of varying sizes, thus broadening compatibility. This solves the problem that in experimental operations, microcentrifuge tubes are typically capped by pressing down with fingers, which is not only prone to finger injury but also inefficient, allowing only one tube to be capped at a time, and the small size of the tubes makes them difficult to secure. To prevent deformation of the microcentrifuge tubes due to pressure on the cap, a rear groove 21 is provided at the position of the outer expansion hole 22 opposite the front groove 20. When capping, the flange of the cap head is pressed into this rear groove 21. To open the cap, a bottle opener is inserted into the rear groove 21 to pry open the cap flange.

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.
