[0002] Centrifuges are devices used to separate components in a mixture of liquids and solid particles or liquids and liquids by centrifugation. They are common instruments in laboratories. Most existing centrifuges use centrifuge baskets to hold test tubes, typically 15 ml, 50 ml, and 100 ml tubes. Due to the large number of tubes, handling them is cumbersome and cannot meet the requirements for rapid centrifugation.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] To maximize the number of rotors that can be adapted to different configurations, a centrifuge cup (7) is provided for placing test tubes, such as... Figure 1-4 As shown, a multi-tube centrifuge rotor includes a centrifuge disc 1, a centrifuge basket 4, and a centrifuge cup 7. The centrifuge disc 1 is horizontally arranged inside the centrifuge body. The centrifuge disc 1 can be made of metal or other high-strength plastic. It is concentrically mounted on a drive motor in the middle so that it can rotate to perform centrifugation operations.

[0029] The centrifuge disc 1 has multiple assembly stations 2 circumferentially, each assembly station 2 having an area adapted to the centrifuge basket 4. The opposite sides of each assembly station 2 are parallel assembly surfaces, parallel to the corresponding sides of the centrifuge basket 4. The centrifuge basket 4 has an open placement cavity at the top, which is cylindrical. The two sides of the centrifuge basket 4 are hinged between the two assembly surfaces via hinge shafts 9, allowing the centrifuge basket 4 and centrifuge disc 1 to rotate. The hinge shafts 9 are located on the upper edge of the centrifuge basket 4. The assembly stations 2 are larger than the centrifuge basket 4, allowing the centrifuge basket 4 to rotate within the assembly stations 2. The centrifuge basket 4 rotates via the hinge shafts 9 under centrifugal force. The centrifuge cup 7 is adapted to the shape of the placement cavity, and has multiple arrayed placement holes 8 on it. Based on the capacity of the test tubes, the depth and diameter of the placement hole 8 are adjusted accordingly for test tube capacities of 15 ml, 50 ml, and 100 ml. The number of test tubes is also adjusted based on the volume of the centrifuge cup 7. In this embodiment, without interference, the maximum number of tubes is 15ml*24*4, 50ml*10*4, and 100ml*6*4. The test tubes come with caps. Compared to traditional round cups, this application increases the maximum number of tubes to 15ml*7*6, 50ml*3*6, and 100ml*1*6, thus increasing the number of tubes that can be placed during construction and better meeting the needs of users.

[0030] To ensure the stability of the centrifuge cup 7 during the centrifugation process, the centrifuge cup 7 and the centrifuge basket 4 are interference fit. A push rod corresponding to the centrifuge cup 7 is provided at the bottom of the centrifuge basket 4. After centrifugation is completed, the centrifuge cup 7 is pushed upward by the push rod, so that the centrifuge cup 7 overcomes the resistance and is pushed out of the centrifuge basket 4, thereby realizing quick pick-up and drop.

[0031] Furthermore, the centrifuge cup 7, which can be quickly removed and placed, enables rapid replacement. After centrifugation, there is no need to place the sediment; the centrifuge cup 7 can be removed and placed separately for the centrifugation of the next batch of materials.

[0032] In an optional embodiment, the centrifuge disc 1 is made of an elastic material, preferably rubber or silicone, which has sufficient deformation elasticity and cushioning capacity to facilitate insertion into the centrifuge basket 4. After insertion, it ensures stability through its own elasticity and friction. In addition, the placement hole 8 is adapted to the corresponding test tube (same diameter). When the centrifuge cup 7 is inserted into the centrifuge basket 4, it deforms, thereby compressing the placement hole 8 to deform. This causes the test tube and the placement hole 8 to deform and squeeze and fix the test tube. This squeezing is a flexible squeezing and will not damage the test tube.

[0033] Inside the placement cavity, there is a sliding push plate 5 that is adapted to the cavity. The push plate 5 makes the centrifuge cup 7 bear the force evenly. The push rod passes through the bottom of the centrifuge basket 4 and is rotatably connected to the middle of the push plate 5. Specifically, the push rod can be a bolt, threadedly fitted to the centrifuge basket 4, and the upper end is rotatably connected to the push plate 5 through a flange or washer.

[0034] In another alternative embodiment, the placement hole 8 can also be configured to have an interference fit with the corresponding test tube.

[0035] In one optional embodiment, the centrifuge cup 7 is square, designed to maximize the size of the rotor. Based on 15ml, 50ml, and 100ml centrifuge tubes (with caps), the centrifuge cup 7 is designed with the maximum number of holes per arrangement. The corners of the centrifuge cup 7 are smoothly transitioned by rounded arc surfaces, and the bottom of the centrifuge cup 7 has an arc transition. Correspondingly, the push plate 5 has an upper surface that matches the bottom surface of the centrifuge cup 7. The assembly station 2 is square, and its corners are smoothly transitioned by rounded arc surfaces to meet the longitudinal sliding requirements of the push plate 5.

[0036] In an optional embodiment, due to the increase in the number of test tubes, the centrifugal force on the centrifuge basket 4 during centrifugation increases significantly. Therefore, reinforcing blocks 6 corresponding to the hinge shaft 9 are provided on both sides of the centrifuge basket 4. The centrifuge basket 4 can be made of high-strength plastic, and the reinforcing blocks 6 are integrally formed with the centrifuge basket 4, thereby improving the strength of the centrifuge basket 4.

[0037] A weight-reduction notch 3 is provided between any two adjacent assembly stations 2 to reduce the weight of the centrifuge disc 1. Two parallel hinge plates corresponding to the centrifuge basket 4 are formed through the weight-reduction notch 3. The hinge plates are provided with through holes corresponding to the hinge shaft 9. The hinge shaft 9 passes through the centrifuge basket 4 from the weight-reduction notch 3 and extends into the reinforcing block 6, thereby satisfying the assembly of the hinge shaft 9 and reducing the assembly difficulty.

[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 shall be within the scope of protection of the pending claims of the present utility model.
