Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and more specifically, to a centrifuge for pharmaceutical production. Background Technology

[0002] A pharmaceutical centrifuge is a widely used device in medical research and clinical practice. It is mainly used to separate biomedical samples, such as blood, cells, and proteins. Its working principle is to use centrifugal force to separate different substances in a mixture according to their density and mass differences, thereby achieving the purpose of separation.

[0003] In pharmaceutical centrifuges, the fixed connection between the test tube rack and the centrifuge rotor (rotor) (i.e., an integrated design, not detachable or replaceable) presents a series of significant drawbacks, especially in the context of modern laboratories prioritizing efficiency, flexibility, and cost-effectiveness. The main disadvantages include:

[0004] Incompatible with different test tube sizes: Different experiments require test tubes / containers of different capacities, diameters or heights (such as 1.5mL centrifuge tubes, 15mL conical tubes, 50mL centrifuge tubes, blood bags, PCR tubes, etc.). Fixed test tube racks can only accommodate one or a very small number of sizes. Changing the type of experiment means that the entire centrifuge or rotor needs to be replaced (if the rotor can be replaced, the cost is high).

[0005] In view of this, a centrifuge for pharmaceutical production is provided to overcome the above-mentioned defects. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a centrifuge for pharmaceutical production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A centrifuge for pharmaceutical production is applied to a medical centrifuge body. The medical centrifuge body includes a turntable, and a placement groove is annularly carved on the top of the turntable. A test tube rack is connected to the placement groove through multiple sets of positioning mechanisms. Test tube bodies are placed in the test tube rack. A base plate is fixedly connected to one side of the placement groove. A vertical rod is provided on the top of the base plate. An adjustment mechanism is provided on one side of the vertical rod. A drive mechanism is connected to one side of the adjustment mechanism. A locking mechanism is provided between the drive mechanism and the test tube rack.

[0009] Preferably, the test tube rack has multiple placement openings equidistantly cut at the top, and the test tube body is placed inside the placement openings.

Fixing blocks are symmetrically arranged on both sides of the adjustment block. Fixing ports are symmetrically excavated on both sides of the inner wall of the adjustment groove, and the fixing ports and fixing blocks are structurally matched.

[0012] Preferably, the driving mechanism includes a driving bushing, a driving rod, and a driving plate. The driving bushing is disposed on one side of the adjusting block, and the driving rod is connected to the driving bushing via a bearing.

[0029] Example 1

[0030] like Figure 1-5 As shown, a pharmaceutical centrifuge according to an embodiment of the present invention is applied to a medical centrifuge body 1. The medical centrifuge body 1 includes a turntable 2. The top of the turntable 2 is annularly carved with a placement groove 3. A test tube rack 5 is connected to the placement groove 3 through multiple sets of positioning mechanisms 4. A test tube body 6 is placed in the test tube rack 5. A base plate 7 is fixedly connected to one side of the placement groove 3. A vertical rod 8 is provided on the top of the base plate 7. An adjustment mechanism 9 is provided on one side of the vertical rod 8. A driving mechanism 10 is connected to one side of the adjustment mechanism 9. A locking mechanism 11 is provided between the driving mechanism 10 and the test tube rack 5. Multiple placement openings are equidistantly carved on the top of the test tube rack 5, and the test tube body 6 is placed in the placement opening.

[0031] In this embodiment, the test tube rack 5 is placed in the placement groove 3. The buckle of the positioning mechanism 4 automatically engages with the corresponding structure (groove) of the test tube rack 5, restricting the horizontal movement of the test tube rack 5, but not completely locked (it can be manually pulled out). The user rotates the drive mechanism 10, which drives the locking mechanism 11 to move laterally. Under rotation, the drive mechanism 10 adjusts the position of the locking mechanism 11 on one side to ensure that the engaging structure on the locking mechanism 11 corresponds. Then, under the drive of the sliding structure in the adjustment mechanism 9, the drive mechanism 10 moves the components inside the locking mechanism 11 and engages the components inside the locking mechanism 11. Under this engagement, the test tube rack 5 is stabilized in the placement groove 3. When the sliding component reaches the end of its stroke, the components inside it engage, and the engaging structure on it is locked.

[0032] Example 2

[0033] The positioning mechanism 4 includes a T-shaped block 12 and a T-shaped opening 13. The T-shaped blocks 12 are symmetrically arranged on both sides of the inner cavity of the placement groove 3, and the T-shaped openings 13 are symmetrically opened on both sides of the test tube rack 5. The T-shaped blocks 12 and T-shaped openings 13 are structurally matched. The T-shaped blocks 12 are fixed to the two side walls of the inner cavity of the placement groove 3. They are hard metal protrusions with an inverted T-shaped cross-section. The T-shaped openings 13 are opened on both sides of the test tube rack 5 and are grooves that mirror the T-shaped blocks 12. The T-shaped blocks 12 are engaged into the T-shaped openings 13, so that the test tube rack 5 is fixed in the placement groove 3 by engaging.

[0034] The adjusting mechanism 9 includes an adjusting groove 14, an adjusting block 15, a fixing block 16, and a fixing opening 17. The adjusting groove 14 is opened on one side of the vertical rod 8. The adjusting block 15 is slidably disposed in the adjusting groove 14. The fixing blocks 16 are symmetrically arranged on both sides of the adjusting block 15. The fixing openings 17 are symmetrically carved on both sides of the inner wall of the adjusting groove 14, and the fixing openings 17 and fixing blocks 16 are structurally matched. The adjusting groove 14 is fixedly opened on one side of the vertical rod 8, serving as the track and support base for the sliding of the adjusting block 15. The adjusting block 15 is slidably disposed in the adjusting groove 14 and can move longitudinally along the groove. The fixing blocks 16 are symmetrically installed on both sides of the adjusting block 15. 6. The fixing block 16 is located on both sides of the adjusting block 15, while the fixing port 17 is symmetrically carved on both sides of the inner wall of the adjusting groove 14. The two structures are matched. When the fixing block 16 is embedded in the fixing port 17, a mechanical lock is formed, which restricts the movement of the adjusting block 15. When the adjusting block 15 slides in the groove, the matching relationship between the fixing block 16 and the fixing port 17 determines the position locking point, ensuring that the mechanism remains stable after adjustment. The adjusting block 15 moves freely along the adjusting groove 14 to the target position. The movement trajectory is constrained by the geometry of the groove to ensure linear translation. After reaching the target position, the fixing block 16 is embedded in the corresponding fixing port 17, and rigid fixation is achieved through structural matching.

[0035] The drive mechanism 10 includes a drive bushing 18, a drive rod 19, and a drive plate 20. The drive bushing 18 is disposed on one side of the adjusting block 15. The drive rod 19 is connected to the drive bushing 18 through a bearing. The drive plate 20 is connected to one side of the drive rod 19. The drive bushing 18 is directly fixed to one side of the adjusting block 15, forming a support base for the mechanism. The user operates the shaft, and the drive rod 19, which is mounted in the drive bushing 18 through a bearing, transmits rotational force. The drive plate 20 is a flat plate fitted on the drive rod 19, which converts the rotational motion into horizontal displacement. The drive rod 19, which is connected to the drive bushing 18 through a bearing, adjusts the drive plate 20 fitted on the outside and the locking block 23 at its bottom when rotating, so that the locking block 23 is positioned above the locking groove 22 under adjustment.

[0036] The locking mechanism 11 includes a locking plate 21, a locking groove 22, and a locking block 23. The locking plate 21 is disposed on one side of the test tube rack 5. The locking groove 22 is opened on the top of the locking plate. The locking block 23 is fixedly disposed on the bottom of the drive plate 20, and the locking block 23 and the locking groove 22 are structurally matched. The locking plate 21 is fixedly installed on one side of the test tube rack 5, forming a static base for the locking mechanism. The locking groove 22 is opened on the top of the locking plate 21, serving as the embedding target position for the locking block 23. The locking block 23 is rigidly fixed to the bottom of the drive plate 20, and its position moves synchronously with the drive plate 20. When the drive plate 20 is pushed down by the drive mechanism (such as the drive rod 19 mentioned above), the locking block 23 moves down synchronously, and the locking block 23 is precisely embedded in the locking groove 22. Through structural matching, a mechanical interlock is formed, restricting the displacement freedom of the test tube rack 5.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, firstly, the T-shaped block 12 engages with the T-shaped opening 13, so that the test tube rack 5 is fixed in the placement groove 3 by engaging. Then, the drive rod 19, which is connected to the drive shaft sleeve 18 by a bearing, is rotated. Under rotation, the drive rod 19 adjusts the drive plate 20 sleeved on the outside and the locking block 23 at its bottom, so that the locking block 23 is positioned above the locking groove 22 under adjustment. Then, the adjusting block 15 slides vertically downward in the adjusting groove 14, so that the components on the adjusting block 15 move down. Under this sliding downward movement, the locking block 23 engages with the locking groove 22. Under this engagement, the test tube rack 5 is stabilized in the placement groove 3. When the adjusting block 15 slides vertically to one side in the adjusting groove 14, the fixing block 16 on it engages with the fixing opening 17, so that the engaging structure on it is locked.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
