[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a high-efficiency laboratory centrifuge, including a centrifugal rotor 1 installed on a motor, a plurality of mounting grooves 2 are provided on the outer ring of the centrifugal rotor 1, a first clamping plate 3 and a second clamping plate 4 are provided in the mounting grooves 2, the first clamping plate 3 and the second clamping plate 4 are both arranged in a triangular structure, a locking mechanism for driving the second clamping plate 4 to move toward the first clamping plate 3 is installed in the opening on the outer side of the mounting groove 2, and a bottom plate 9 is provided at the bottom of the first clamping plate 3 and the second clamping plate 4.
[0021] In this embodiment, the locking mechanism includes a U-shaped plate 7, a screw 5, a handwheel 6 and a bearing. The U-shaped plate 7 is installed in the opening on the outside of the installation groove 2. The U-shaped plate 7, the first clamping plate 3 and the second clamping plate 4 are all inclined. The bearings are embedded on the outer surface of the second clamping plate 4. The U-shaped plate 7 is provided with a screw hole at the inner ring of the bearing. The screw 5 is threadedly connected to the screw hole. One end of the screw 5 is installed in the inner ring of the bearing, and the other end is fixedly connected to the handwheel 6.
[0022] Among them, the test tube can be tilted and positioned by the inclined first clamping plate and the second clamping plate. The tilted test tube can make the sample better interact with the centrifugal force of the centrifuge during the centrifugation process. Since the centrifugal force is generated along the direction of the rotation axis of the centrifuge, the tilted test tube can make the sample form a more uniform sedimentation layer during the centrifugation process, thereby improving the separation efficiency.
[0023] In this embodiment, both sides of the installation groove 2 are inclined with slide grooves 12, both sides of the second clamping plate 4 are inclined with sliders 13, the sliders 13 are slidably installed in the slide grooves 12, compression springs 14 are installed between the sliders 13 and the slide grooves 12, and both sides of the first clamping plate 3 are installed on the inner wall surface of the installation groove 2. The second clamping plate can be positioned through the slide grooves and the sliders, so that the second clamping plate can only move along the slide grooves, thereby preventing the second clamping plate from falling from the installation groove.
[0024] In this embodiment, the bottom plate 9 of the first clamping plate 3 is provided with a groove 11 , the bottom plate 9 of the second clamping plate 4 is protruded to form an insertion portion 10 , and a portion of the insertion portion 10 extends into the groove 11 .
[0025] In this embodiment, the first clamping plate 3 and the bottom plate 9 as well as the second clamping plate 4 and the bottom plate 9 are all integrally injection molded, which reduces the cost and enables the first clamping plate and the second clamping plate to be quickly produced and molded.
[0026] In this embodiment, a plurality of fixing holes 8 are provided in the middle of the centrifugal rotor 1. After the screws pass through the fixing holes, the centrifugal rotor can be smoothly fixed on the motor.
[0027] When in use, the test tube can be inserted between the first clamping plate and the second clamping plate. At this time, the hand wheel can be rotated according to the diameter of the test tube. The rotation of the hand wheel drives the screw rod to move along the screw hole. The movement of the screw rod drives the second clamping plate to move stably along the slide groove. After the second clamping plate is close to the first clamping plate, the test tube can be clamped and fixed so that the outer wall surface of the test tube can contact the inner side surfaces of the first clamping plate and the second clamping plate at different positions, thereby increasing adaptability. In the process of moving the second clamping plate, the insertion part can enter the groove, so that the bottom of the test tube can be restricted by the bottom plate, thereby preventing the test tube from falling out downwards. The bottom plates can be prevented from getting stuck through the groove and the insertion part, thereby bringing the first clamping plate and the second clamping plate closer together.
[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
