Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a centrifuge. Background Technology

[0002] A centrifuge is an experimental device that separates substances by generating centrifugal force through high-speed rotation. It separates components in a liquid mixture based on their density or size by utilizing the density differences of different substances in the liquid. The centrifuge rotor generates a powerful centrifugal force when rotating at high speed. If the samples are not placed asymmetrically, the rotor will become unbalanced, causing excessive vibration during centrifuge operation, which may even damage the equipment or affect the separation effect. However, some current centrifuges require careful inspection and confirmation of symmetrical placement of the solution before use. This process requires operators to spend more time checking and ensuring that each sample is placed symmetrically within the centrifuge. This means that operators need higher concentration and more precise operation, which can easily increase workload and fatigue, especially when processing large numbers of samples. It also makes the operation more cumbersome, thus prolonging the overall operation time and affecting work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problem that some centrifuges require careful inspection and confirmation of symmetrical solution placement during use. This operation demands higher concentration and precision from the operator, which not only increases workload and fatigue but also makes the process more cumbersome, extending overall operation time and affecting work efficiency. Therefore, this invention proposes a new centrifuge solution.

[0004] The technical solution of this utility model is as follows: A centrifuge includes a centrifuge body and a rotating trough opened in the centrifuge body. The rotating trough is provided with a rotating centrifuge block inside. The centrifuge also includes: a centrifuge trough fixedly connected in the centrifuge block for the centrifugation solution to be put in; a pressing mechanism set in the centrifuge block so that two symmetrical centrifuge troughs can be closed or opened simultaneously; and a locking plate mechanism installed in the centrifuge block and linked to the pressing mechanism.

[0005] Optionally, the pressing mechanism includes a first linkage U-shaped rod, a second linkage U-shaped rod, and a third linkage U-shaped rod arranged sequentially in a vertical manner. The top ends of the first linkage U-shaped rod, the second linkage U-shaped rod, and the third linkage U-shaped rod all slide through the centrifugal block and correspond to the centrifugal groove. Sliding blocks are fixedly connected to the outer walls of both ends of the first linkage U-shaped rod, the second linkage U-shaped rod, and the third linkage U-shaped rod. A return spring is fixedly connected to the upper surface of each sliding block, and the top end of the return spring is fixedly connected to the inner top wall of the centrifugal block.

[0006] Optionally, the clamping mechanism includes a sliding baffle plate slidably connected inside the centrifuge block. Each end of the sliding baffle plate near the sliding abutment is provided with an elliptical groove that engages with the corresponding first linkage U-shaped rod, second linkage U-shaped rod, and third linkage U-shaped rod. The sliding abutment abuts into the elliptical groove to drive the sliding baffle plate out of the centrifuge tank.

[0007] Optionally, the end of the sliding baffle away from the elliptical groove is provided with an arc-shaped groove for locking the solution container.

[0008] Optionally, the centrifuge body is equipped with an operation panel for controlling the switching of centrifuge blocks.

[0009] Optionally, the centrifuge body is characterized by having a rotating cover rotatably connected to its top via a hinge.

[0010] Optionally, the outer wall of the centrifuge tank is fixedly connected with a support block for supporting the horizontal sliding of the sliding baffle plate, and an elastic rope is fixedly connected to the upper surface of the sliding baffle plate. The end of the elastic rope away from the sliding baffle plate is fixedly connected to the support block.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes the coordinated structure of a centrifuge block, centrifuge tank, pressing mechanism, and clamping plate mechanism to press corresponding first, second, and third linkage U-shaped rods, forcing the operator to symmetrically place the solution containers into the centrifuge tank. This not only avoids the tedious manual judgment and adjustment but also eliminates the need for repeated checks on container symmetry, reducing the risk of operational errors and making the operation simpler and more intuitive. Furthermore, this design improves the safety of the centrifugation process, reduces equipment malfunctions caused by improper operation, and indirectly enhances operator comfort and overall work efficiency.

[0024] Example

[0025] like Figures 1 to 4 As shown, the present invention discloses a centrifuge, including a centrifuge body 1 and a rotating tank 2 formed inside the centrifuge body 1. A rotating cover 5 is rotatably connected to the top of the centrifuge body 1 via a hinge. The centrifuge body 1 is equipped with an operation screen 6 for controlling the switching of centrifuge blocks 3. The operation screen 6 uses a simplified graphical interface and an intuitive touch screen, allowing the operator to quickly set various parameters and avoid tedious adjustment processes. The rotating tank 2 contains rotating centrifuge blocks 3 and also includes: centrifuge tanks 31 fixedly connected inside the centrifuge blocks 3 for placing centrifugation solutions; support blocks 35 fixedly connected to the outer walls of the centrifuge tanks 31 to support the horizontal sliding of sliding baffle plates 4; elastic ropes 43 fixedly connected to the upper surface of the sliding baffle plates 4, with one end of the elastic rope 43 away from the sliding baffle plates 4 fixedly connected to the support blocks 35; a pressing mechanism set inside the centrifuge blocks 3 to allow the two symmetrical centrifuge tanks 31 to close or open simultaneously; and a plate mechanism installed inside the centrifuge blocks 3 that is linked to the pressing mechanism for switching.

[0026] Furthermore, the pressing mechanism includes a first linkage U-shaped rod 32, a second linkage U-shaped rod 33, and a third linkage U-shaped rod 34 arranged sequentially, one above the other. These rods can be activated manually by pressing. Simultaneously, telescopic motors are located at the ends of the first linkage U-shaped rod 32, the second linkage U-shaped rod 33, and the third linkage U-shaped rod 34. These telescopic motors are integrated with an electronic control system to achieve automated control. This control method utilizes electronic controllers and sensors to precisely adjust the motor's operation, thereby controlling the movement of the telescopic components through simple input methods (such as shortcut keys). The top ends of the first linkage U-shaped rod 32, the second linkage U-shaped rod 33, and the third linkage U-shaped rod 34 all slide through the centrifuge block 3 and correspond to the centrifuge tank 31. Sliding blocks 2341 are fixedly connected to the outer walls of both ends of the first linkage U-shaped rod 32, the second linkage U-shaped rod 33, and the third linkage U-shaped rod 34. A return spring 2342 is fixedly connected to the upper surface of each sliding block 2341. The return spring 2342 ensures that the first linkage U-shaped rod 32, the second linkage U-shaped rod 33, and the third linkage U-shaped rod 34 return to their original positions after being pressed and released. The top end of the return spring 2342 is fixedly connected to the inner top wall of the centrifuge block 3.

[0027] Furthermore, the clamping mechanism includes a sliding baffle plate 4 slidably connected within the centrifuge block 3. The end of the sliding baffle plate 4 away from the elliptical slide groove 41 has an arc-shaped clamping groove 42 for clamping the solution container. The arc-shaped clamping groove 42 is activated by releasing the first linkage U-shaped rod 32, the second linkage U-shaped rod 33, and the third linkage U-shaped rod 34. At this time, the sliding block 2341 can be restored to its original position by the elastic pull of the return spring 2342. The sliding baffle plate 4 will also slide into the centrifuge tank 31 by the elastic pull of the elastic rope 43. Finally, the arc-shaped clamping groove 42 and the centrifuge tank 31 firmly abut against the solution container. The sliding baffle plate 4 is provided with an elliptical groove 41 at one end near the sliding block 2341, which is sleeved with the corresponding first linkage U-shaped rod 32, second linkage U-shaped rod 33 and third linkage U-shaped rod 34. The sliding block 2341 is inserted into the elliptical groove 41 to drive the sliding baffle plate 4 out of the centrifugal tank 31.

[0028] In this embodiment, when a centrifuge is required, such as Figure 1 As shown, first rotate the rotating cover 5 upwards to open it, so that the centrifugal block 3 inside the rotating groove 2 is exposed to the light. Figure 2As shown, the container containing the solution to be centrifuged is placed into any centrifuge tank 31. The sliding baffle 4 within the centrifuge tank 31 prevents the container from being fully inserted. Then, one of the pair of first linkage U-shaped rods 32 can be pressed. The pressed rod moves the corresponding sliding block 2341 downwards and into the corresponding elliptical groove 41, causing the elliptical groove 41 to disengage the sliding baffle 4 from the centrifuge tank 31. Now, one of the two solution containers can be placed into the corresponding centrifuge tank 31. The corresponding first linkage U-shaped rod 32 is then held down, ensuring the other solution container can only be placed into the centrifuge tank 31 corresponding to one of the solution containers. When placed into a centrifuge tank 31 that is asymmetrical with one of the containers, the sliding baffle 4 within that tank will block it, preventing asymmetrical placement of the two solution containers within the centrifuge tank 31. The second linkage U-shaped rod 33 and the third linkage U-shaped rod 34 operate in the same way as above, and will not be described in detail here.

[0029] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
